425,125 | <p>I'm working with XML that was designed by somebody who got paid by the level of nesting. The different xml files always looks something like this:</p>
<pre><code><Car>
<Color>
<Paint>
<AnotherUselessTag>
<SomeSemanticBs>
<TheImportantData>
</code></pre>
<p>With LINQ its easy to get what I want: ( not exactly, but you get the point )</p>
<pre><code>from x in car.Descendants("x")
from y in x.Descendants("y")
from z in y.Descendants("z")
select z.WhatIWant();
</code></pre>
<p>I'm asking if there is a better way to do this? Some way of navigating the DOM with Linq?</p>

425,130 | <p>One of our clients has an application (FoxPro 9) running on top of a SQL Server 2005 backend. Intermittently, they are losing their ODBC connection with the SQL Server database. Below is the initial error information:</p>
<blockquote>
<p>Err Msg: Connectivity error: [Microsoft][ODBC SQL Server Driver][DBNETLIB]ConnectionRead (recv()). </p>
<p>ODBC Err Msg: [Microsoft][ODBC SQL Server Driver][DBNETLIB]ConnectionRead (recv()). </p>
<p>SQL State: 01000 </p>
<p>ODBC Err No: 10054 </p>
<p>ODBC Handle: 1 </p>
<p>FoxPro Error No: 1526 </p>
</blockquote>
<p>We cannot duplicate this error on command. We have tried any number of solutions to no avail. One such hardware base solution which we found was described in: <a href="http://support.microsoft.com/kb/942861/en-us" rel="nofollow noreferrer">http://support.microsoft.com/kb/942861/en-us</a> </p>
<p>I mention this because it almost perfectly matches what we have been seeing. However, we have implemented all the workarounds listed in that posting (and in this one <a href="http://support.microsoft.com/kb/948496" rel="nofollow noreferrer">http://support.microsoft.com/kb/948496</a> ) - and the problem still continues. </p>
<p>This issue seems to show itself after the execution of long running queries, but we are not receiving any timeout errors, either from the application, or from SQL Server. I do not believe that this is the result of an idle timeout, because it sometimes occurs in the middle of an executing program.</p>
<p>I am not a hardware guy, but both the network, and the server (Windows Server 2003), appear to be fast and well designed. There are times however, when the database server is under significant stress.</p>
<p>If anyone has any suggestions on things we could try...please let us know!</p>

425,158 | <p>Is there a way to restrict certain tables from the mysqldump command?</p>
<p>For example, I'd use the following syntax to dump <em>only</em> <code>table1</code> and <code>table2</code>:</p>
<pre><code>mysqldump -u username -p database table1 table2 > database.sql
</code></pre>
<p>But is there a similar way to dump all the tables <em>except</em> table1 and table2? I haven't found anything in the mysqldump documentation, so is brute-force (specifying all the table names) the only way to go?</p>

425,189 | <p>I'm creating a small code plugin which allows you to do some things with arrays. I do not wish to add the functions to the array object using a prototype construction, what I want is that people can do something like:</p>
<pre><code>arrayFunction( [1, 2, 3] ).someSpecialArrayFunction();
</code></pre>
<p>Thus leaving the normal array object unaltered.<br>
So I came up with the following construction (which was inspired on the jQuery source code) :</p>
<pre><code>var arrayFunction = window.arrayFunction = function(array) {
return new arrayFunction.fn.init(array);
}
arrayFunction.fn = arrayFunction.prototype = {
init: function(array){
this.a = array;
//should I return something here?
},
someSpecialArrayFunction: function(){
//Super cool custom stuff here.
}
}
</code></pre>
<p>However this does not work (obviously). What should happen in the init function()?</p>
<p>The error right now is that when I try:</p>
<pre><code> arrayFunction(array).someSpecialArrayFunction();
</code></pre>
<p>it says that someSpecialArrayFunction() is not a function?</p>
<p>How should one do this?</p>
<p><B>edit</b><br>
Yes, this is indeed a simpliefied example. The actual thing has way more methods.</p>
<p>Also, I just though of how awesome it would be if it also supported chaning, how would you do that?</p>

425,191 | <p>I want to make a horizontal list in my application, which will display images. While this is quite trivial, I want the image to open a flex alert box (the built in one) and display some text. For example, I will have an image of the .NET logo and I will enter some text somewhere (like in a collection), and this text will be displayed in the alert box.</p>
<p>How could I do this? There doesn't seem to be an event handler for clicking an item member in a flex horizontal list?</p>
<p>Thanks</p>

425,226 | <p>I have a ProgressBar that uses the marquee style when a report is being generated. The reason I am doing this is because the ReportViewer control I use takes some time to generate the report thus making the form unresponsive. I generate the report using a thread so the ProgressBar can show that the program is working. However, when I start the thread the ProgressBar freezes. I have already tried the BackgroundWorker but that didn't work so I used my own threading.</p>
<p>The reason I use the Invoke() method is because I can't make changes to the ReportViewer control on the thread I created because it was created on the UI thread.</p>
<p>The method that takes the most time processing is the RefreshReport() method of the ReportViewer control which is why I'm trying to do that on its own thread instead of the UI thread.</p>
<p>Any help would be appreciated. Thanks.</p>
<p>Here is the code for my thread variable:</p>
<pre><code>Private t As New Thread(New ParameterizedThreadStart(AddressOf GenerateReport))
</code></pre>
<p>Here is the code for the button that generates the report:</p>
<pre><code>Private Sub btnGenerateReport_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnGenerateReport.Click
pbReports.Style = ProgressBarStyle.Marquee
If t.ThreadState = ThreadState.Unstarted Then
t.IsBackground = True
t.Start(ReportType.Roads)
ElseIf t.ThreadState = ThreadState.Stopped Then
t = Nothing
t = New Thread(New ParameterizedThreadStart(AddressOf GenerateReport))
t.IsBackground = True
t.Start(ReportType.Roads)
End If
End Sub
</code></pre>
<p>Here is the code that generates the report:</p>
<pre><code>Public Sub GenerateReport(ByVal rt As ReportType)
If rvReport.InvokeRequired Then
Dim d As New GenerateReportCallBack(AddressOf GenerateReport)
Me.Invoke(d, New Object() {rt})
Else
rvReport.ProcessingMode = ProcessingMode.Remote
rvReport.ShowParameterPrompts = False
rvReport.ServerReport.ReportServerUrl = New Uri("My_Report_Server_URL")
rvReport.ServerReport.ReportPath = "My_Report_Path"
rvReport.BackColor = Color.White
rvReport.RefreshReport()
End If
If pbReports.InvokeRequired Then
Dim d As New StopProgressBarCallBack(AddressOf StopProgressBar)
Me.Invoke(d)
Else
StopProgressBar()

425,235 | <p>What is the correct way to close or reset a TcpClient connection?
We have software that communicates with hardware but sometimes something
goes wrong and we are no longer to communicate with it, until we restart the software.</p>
<p>I have tried forcing TcpClient.Close() and even setting it to null but that doesn't work.
Only a complete restart of the software works.</p>
<p>Suggestions?</p>
<hr>
<p>I can't use the using keyword because TpcClient is only defined in one location, but used throughout the library. (And there is only one connection at any given time)</p>
<p>It's a library that handles communication. The software itself can call the ResetConnection() method of the Controller class (which represents the hardware).</p>
<p>It currently looks like</p>
<pre><code>if (tcpClient != null)
{
tcpClient.Close();
tcpClient = null;
}
</code></pre>
<p>Now from what I've read here I should use tcpClient.Dispose() instead of " = null"</p>
<p>I'll give that a try and see if it makes a difference.</p>

425,281 | <p>I keep getting stuck conceptually on deciding an Exception-handling structure for my project.</p>
<p>Suppose you have, as an example:</p>
<pre><code>public abstract class Data {
public abstract String read();
}
</code></pre>
<p>And two subclasses FileData, which reads your data from some specified file, and StaticData, which just returns some pre-defined constant data.</p>
<p>Now, upon reading the file, an IOException may be thrown in FileData, but StaticData will never throw. Most style guides recommend propagating an Exception up the call stack until a sufficient amount of context is available to effectively deal with it.</p>
<p>But I don't really want to add a throws clause to the abstract read() method. Why? Because Data and the complicated machinery using it knows nothing about files, it just knows about Data. Moreover, there may be other Data subclasses (and more of them) that never throw exceptions and deliver data flawlessly.</p>
<p>On the other hand, the IOException is necessary, for if the disk is unreadable (or some such) an error <em>must</em> be thrown. So the only way out that I see is catching the IOException and throwing some RuntimeException in its place.</p>
<p>Is this the correct philosophy?</p>

425,294 | <p>Does anybody know what is the best approach to accessing a sql view through Grails (or if this is even possible)? It seems an obvious way of doing this would be to use executeQuery against the view to select a collection of rows from the view which we would not treat as a list of domain objects. However, even in this case it is not obvious which domain class to run executeQuery against, since really we are just using that domain class in order to run the query against a completely unrelated entity (the view).</p>
<p>Would it be preferred to create a domain class representing the view and we could then just use list() against that domain class? It seems like there would be problems with this as Grails probably expects to be able to insert, update, delete, and modify the table schema of any domain class.</p>

425,306 | <p>update: I know there is no one best way to do everything. Sorry for not saying that right off. In the context of the data-access tutorials, if you had to do the project he did in that tutorial, would you do what he did or would use use MVC, if you had to choose one of them?</p>
<p><strong>Update:</strong> Is MVC the more appropriate way to program asp.net applications, instead of the tutorials found here:</p>
<p><a href="http://www.asp.net/Learn/data-access/" rel="nofollow noreferrer">http://www.asp.net/Learn/data-access/</a></p>
<p><strong>Original:</strong></p>
<p>I ask, because I initially learned about MVC with Java applications, then things like RoR, and Django. These other projects and companies spoke as if MVC had been around for a very long time, and from what I found out it had. Then Microsoft started putting MVC into the .net framework.</p>
<p>I ask because I don't know how to design things very well and thought I was doing well to emulate what's on the asp.net site with Scott Mitchell's tutorial. I thought that creating abstract layers in a BLL was the way to go until I found out about MVC and now asp.net's MVC.</p>
<p>I honestly don't know what the "right" way is to do things. I just create what I need, but I can't help feel like I am missing something.</p>
<p>Is MVC the correct way to start doing things in large projects, specifically I mean MVC and ASP.NET, but could just as well mean PHP and one of their MVC frameworks.</p>
<p>I'd like to settle on a standard way of doing things...for now anyway.</p>
<p>And, out of curiosity, why did Microsoft only now start doing MVC?</p>
<p><strong>UPDATE:</strong> Is MVC better than the current tutorial set on asp.net?</p>
<p>I'm referring to the Scott Mitchell tutorials where he creates the BLL for abstraction. Or is that a linq question as well. I should have said that I understand the need for keeping logic and presentation separate but unsure the best way to do it. I was using the asp.net tutorials. It worked fine. Then I found out the rest of the world, as I saw it anyway, was using MVC. Then Microsoft started developing MVC, so to me the other method seems obsolete and the wrong way to do things.</p>

425,308 | <p>I'm writing a javascript based photo gallery with a horizontally scrollable thumbnail bar.</p>
<p><a href="http://www.sharehost.co.uk/gallerytest/" rel="nofollow noreferrer">>> My current work-in-progress is here <<</a></p>
<p>I would like the thumbnail bar to stop scrolling when it gets to the last thumbnail. To do this I need to find the total width of the contents of the div - preferably without adding up the widths of all the thumbnail images and margins.</p>
<p>I've put an alert in my window.onload function so I can test the various element dimension functions in different browsers. currently it's showing the value of scrollWidth, which is reported as 1540px by IE and 920px by FireFox, Safari, Opera, etc.</p>
<p>The value 1540 is the correct one for my purposes, Can anyone tell me how to obtain this value in FireFox, etc.</p>

425,350 | <p>An upcoming project of mine is considering a design that involves (what I'm calling) "abstract entity references". It's quite a departure from a more common data model design, but it may be necessary to achieve the flexibility we want. I'm wondering if other architects have experience with systems like this and where the caveats are.</p>
<p>The project has a requirement for a to control access to various entities (logically: business objects; physically: database rows) by various people. For example, we might want to create rules like:</p>
<ul>
<li>User Alice is a member of Company Z</li>
<li>User Bob is the manager of Group Y, which has users Charlie, Dave, and Eve.</li>
<li>User Frank may enter data for [critical business object] X, and also the [critical business objects] in [critical business object group] U.</li>
<li>User George is not a member of Company T but may view the reports for Company T.</li>
</ul>
<p>The idea is that we have a lot of different securable objects, roles, groups, and permissions, and we want a system to handle this. Ideally this system would require little to no coding for new situations once it's launched; it should be very flexible.</p>
<p>In a "traditional" data design, we might have entities/tables like this:</p>
<ul>
<li>User</li>
<li>Company</li>
<li>User/Company Cross-Reference</li>
<li>UserGroup</li>
<li>User/UserGroup Cross-Reference</li>
<li>CBO ("Critical Business Object")</li>
<li>User/CBO Cross-Reference</li>
<li>CBOGroup</li>
<li>User/CBOGroup Cross-Reference</li>
<li>CBO/CBOGroup Cross-Reference</li>
<li>ReportAccess, which is a cross-reference between User and Company specifically for access to reports</li>
</ul>
<p>Note the big number of cross-reference tables. This system isn't terribly flexible as any time we want to add a new means of access we'd need to introduce a new cross-reference table; that, in turn, means additional coding.</p>
<p>The proposed system has all of the major entities (User, Company, CBO) reference a value in a new table called Entity. (In the code we'd probably make all of these entities subclasses of an Entity superclass). Then there's two additional tables that reference Entity
* Group, which is also an Entity "subclass".
* EntityRelation, which is a relation between two entities of any type (including Group). This will probably also have some sort of "Relationship Type" field to explain/qualify the relationship.</p>
<p>This system, at least at first glance, looks like it would meet a lot of our requirements. We might introduce new Entities down the road, but we'd never need to do additional tables to handle the grouping and relationships between these entities, because Group and EntityRelation can already handle that.</p>
<p>I'm concerned, however, whether this might not work very well in practice. The relationships between entities would become very complex and might be very hard for people (users and developers alike) to understand them. Also, they'd be very recursive; this would make things more difficult for our SQL-dependent report writing staff.</p>
<p>Does anyone have experiences with a similar system?</p>

425,372 | <p>So, I've been writing a bunch of ruby gems recently, and one thing I would find convenient is to include the current version (as specified in the gemspec) in the <code>rdoc</code>-generated documentation for my libraries, and in the <code>OptionParser</code>-generated <code>--help</code> sections used by my scripts (which I'm distributing via gem). Any way I can make it easy for my users to figure out which version of library/script they're currently using.</p>
<p>Is there any way I can access the version I specify in my gemspec from the ruby files in my <code>lib/</code> or <code>bin/</code> directories? That way, I don't have to update it multiple places at once - just in my gemspec.</p>
<p>Currently I generate my gemspecs by hand, I haven't jumped on the Rake train yet. If I can't do what I want directly with only what rubygems gives me, would rake or another tool allow me to do this?</p>

425,382 | <p>I am running a query against a providex database that we use in MAS 90. The query has three tables joined together, and has been slow but not unbearably, taking about 8 minutes per run. The query has a fair number of conditions in the where clause:</p>
<p>I'm going to omit the select part of the query as its long and simple, just a list of fields from the three tables that are to be used in the results.</p>
<p>But the tables and the where clauses in the 8 minute run time version are:</p>
<p>(The first parameter is the lower bound of the user-selected date range, the second is the upper bound.)</p>
<pre><code>FROM "AR_InvoiceHistoryDetail" "AR_InvoiceHistoryDetail",
"AR_InvoiceHistoryHeader" "AR_InvoiceHistoryHeader", "IM1_InventoryMasterfile"
"IM1_InventoryMasterfile"
WHERE "AR_InvoiceHistoryDetail"."InvoiceNo" = "AR_InvoiceHistoryHeader"."InvoiceNo"
AND "AR_InvoiceHistoryDetail"."ItemCode" = "IM1_InventoryMasterfile"."ItemNumber"
AND "AR_InvoiceHistoryHeader"."SalespersonNo" = 'SMC'
AND "AR_InvoiceHistoryHeader"."OrderDate" >= @p_dr
AND "AR_InvoiceHistoryHeader"."OrderDate" <= @p_d2
</code></pre>
<p>However, it turns out that another date field in the same table needs to be the one that the Date Range is compared with. So I changed the Order Dates at the end of the WHERE clause to InvoiceDate. I haven't had the query run successfully at all yet. And I've waited over 40 minutes. I have no control over indexing because this is a MAS 90 database which I don't believe I can directly change the database characteristics of.</p>
<p>What could cause such a large (at least 5 fold) difference in performance. Is it that OrderDate might have been indexed while InvoiceDate was not? I have tried BETWEEN clauses but it doesn't seem to work in the providex dialect. I am using the ODBC interface through .NET in my custom report engine. I have been debugging the report and it is running at the database execution point when I asked VS to Break All, at the same spot where the 8 minute report was waiting, so it is almost certainly either something in my query or something in the database that is screwed up.</p>
<p>If its just the case that InvoiceDates aren't indexed, what else can I do in the providex dialect of SQL to optimize the performance of these queries? Should I change the order of my criteria? This report gets results for a specific salesperson which is why the SMC clause exists. The prior clauses are for the inner joins, and the last clause is for the date range.</p>
<p>I used an identical date range in both the OrderDate and InvoiceDate versions and have ran them all mulitiple times and got the same results.</p>

425,400 | <p>How can I "hide" parts of a class so that whoever is using the libary does not have to include headers for all the types used in my class. Ie take the MainWindow class below, ho can I have it so when compiled in a static/dynamic libary, whoever is useing the libary does NOT have to include windows.h, ie HWND, CRITICAL_SECTION, LRESULT, etc do not have to be defined.</p>
<p>I know I could split it into two classes, an abstract class with just the public interface, and an implementation class which is hidden that contains the members that require windows.h.</p>
<p>The problem here is that the visible class can no longer be created itsself, and an additional create function (eg CreateMainWindow) is required. That is fine in this case since it is most likly that just a single instance created on the heap is wanted but for other classes this is not.</p>
<pre><code>class MainWindow
{
HWND hwnd;
int width, height;
std::string caption;
bool started,exited;
bool closeRequest;
unsigned loopThread;
CRITICAL_SECTION inputLock;
Input *input;
public:
static void init_type();
Py::Object getattr(const char *name);
MainWindow(int width, int height, std::string caption);
~MainWindow();
bool CloseRequest(const Py::Tuple &args);
bool CloseRequestReset(const Py::Tuple &args);
HWND GetHwnd();
int GetWidth();
int GetHeight();
Input* GetInput();

Let's say I want to display a splash-screen or something in an OpenGL context (or DirectX for that matter, it's more of a conceptual thing), now, I could either just load a 2048x2048 texture and hope that the graphics card will cope with it (most will nowadays I suppose), but growing with old-school graphics card I have this bad conscience leaning over me and telling me I shouldn't use textures that large.</p>
<p>What is the preferred way nowadays? Is it to just cram that thing into video memory, tile it, or let the CPU do the work and glDrawPixels? Or something more elaborate?</p>

425,407 | <p>I have a javascript function (class) that takes a function reference as one paremter.</p>
<pre><code>function MyClass ( callBack ) {
if (typeof callBack !== 'function')
throw "You didn't pass me a function!"
}
</code></pre>
<p>For reasons I won't go in to here, I need to append something to the function by enclosing it in an anonymous function, but the only way I've been able to figure out how to do it is by adding a public function to <strong>MyClass</strong> that takes the callBack function as a parameter and returns the modified version.</p>
<pre><code>function MyClass () {
this.modifyCallBack = function ( callBack ) {
var oldCallBack = callBack;
callBack = function () {
oldCallBack(); // call the original functionality
/* new code goes here */
}
return callBack;
}
}
/* elsewhere on the page, after the class is instantiated and the callback function defined */
myCallBackFunction = MyClassInstance.modifyCallBack( myCallBackFunction );
</code></pre>
<p>Is it possible to make this work when passing the callBack function as a parameter to the class? Attempting to modify the function in this manner when passign it as a parameter seems to only affect the instance of it in within the class, but that doesn't seem like it's a valid assumption since functions are Objects in javascript, and are hence passed by reference.</p>
<p><strong>Update:</strong> as crescentfresh pointed out (and I failed to explain well), I want to modify the callBack function in-place. I'd rather not call a second function if it's possible to do all of this when the class is instantiated.</p>

425,424 | <p>Suppose I have a datatable like this:</p>
<pre><code> DataTable dt = new DataTable("Woot");
dt.Columns.AddRange(new DataColumn[]{
new DataColumn("ID",typeof(System.Guid)),
new DataColumn("Name",typeof(String))
});
</code></pre>
<p>When I try to bind a control to it:</p>
<pre><code> this.txtName.DataBindings.Add("Text", _dtRow, "Name");
</code></pre>
<p>I get this exception:</p>
<blockquote>
<p>Cannot bind to the property or column
Name on the DataSource. Parameter
name: dataMember</p>
</blockquote>
<p>Any idea why this works on a datatable created by a dataAdapter, but not on a programmaticly created one?</p>

425,429 | <p>I've a problem which is most likely some ugly CSS mistake, but I just can't spot the solution (and a few changes I tried did not help).</p>
<p>Some of in-text hyperlinks (not all!) are shown by Internet Explorer without the following space.</p>
<p><a href="http://blog.mekk.waw.pl/archives/28-Picking-the-games-to-watch.html" rel="nofollow noreferrer">here is the example</a></p>
<p>See the link <em>WatchBot</em> just below the <em>Rationale</em> title (and a few similar links deeper in the article). Firefox, Opera, Chrome, Konqueror - all display it properly: <strong>WatchBot</strong> <em>can</em>. IE (6.0 but IIRC also 7.0) displays it as **WatchBot***can*. </p>
<p>I am using Yui-reset and yui-base. Is it possible that those libraries cause the problem?</p>

425,430 | <p>I'm trying to return an iterator for a vector in a templated class (I'm not sure if that makes a difference, but I've read that may, so I thought I'd mention it). The problem is that I get an error about C++ not supporting default-int when I try this. I've looked online and from what I can see in forums and explanaions, I don't think I'm <em>that</em> far off, it just won't compile.</p>
<pre><code>template<class T>
class Table
{
public:
...
vector<shared_ptr<vector<T>>>::iterator GetRowIterator();
//vector<shared_ptr<vector<CellValueType> > >::const_iterator GetRowIterator();
...
protected:
vector<shared_ptr<vector<CellValueType> > > data; //outside vector is rows, inside vector is columns
...
};
vector<shared_ptr<vector<T> > >::const_iterator Table<T>::GetRowIterator()
{
return data.begin();
}
</code></pre>
<p>The errors that I get are: </p>
<pre><code>error C2146: syntax error : missing ';' before identifier 'GetRowIterator'
error C4430: missing type specifier - int assumed. Note: C++ does not support default-int
</code></pre>
<p><em>Edit:</em><br/>
Changed the end angle brackets so they are not as close together - same error.<br/><br/>
Any thoughts as to why this is occurring?<br/>
As always, thanks for advice/help in advance!</p>

425,439 | <p>I have a partially nfilled array of objects, and when I iterate through them I tried to check to see whether the selected object is <code>null</code> before I do other stuff with it. However, even the act of checking if it is <code>null</code> seem to through a <code>NullPointerException</code>. <code>array.length</code> will include all <code>null</code> elements as well. How do you go about checking for <code>null</code> elements in an array? For example in the following code will throw an NPE for me.</p>
<pre><code>Object[][] someArray = new Object[5][];
for (int i=0; i<=someArray.length-1; i++) {
if (someArray[i]!=null) { //do something
}
}

425,457 | <p>Let's say we have a class, MyParent:</p>
<pre><code>class MyParent
{
public:
template<namespace T>
MyParent()
{
T* Something;
}
};
</code></pre>
<p>And a derived class, which uses this constructor:</p>
<pre><code>class MyDerived : public MyParent
{
public:
MyDerived()
: MyParent<int>()
{
}
};
</code></pre>
<p>Then I get a compiling error, because there's ambiguity. The compiler thinks that the <strong><em>int</em></strong> is a template argument to the class, not the constructor.</p>
<p>How do I specify that I want the <strong><em>int</em></strong> to be an argument to the constructor?</p>

425,512 | <p>I am building a fairly simple CMS. I need to intercept requests for the majority of .aspx pages in my web application, in order to gain complete control over the output. In most cases, the output will be pulled from cache and will just be plain HTML.</p>
<p>However, there still are a couple of pages that I am going to need to use asp: controls on. I assume the best way for me to bypass a few particular requests would be to inherit System.Web.UI.PageHandlerFactory and just call the MyBase implementation when I need to (please correct me if I am wrong here). But how do I transfer all other requests to my custom handler?</p>

425,604 | <p>This is a generalization of the "string contains substring" problem to (more) arbitrary types.</p>
<p>Given an sequence (such as a list or tuple), what's the best way of determining whether another sequence is inside it? As a bonus, it should return the index of the element where the subsequence starts:</p>
<p>Example usage (Sequence in Sequence):</p>
<pre><code>>>> seq_in_seq([5,6], [4,'a',3,5,6])
3
>>> seq_in_seq([5,7], [4,'a',3,5,6])
-1 # or None, or whatever
</code></pre>
<p>So far, I just rely on brute force and it seems slow, ugly, and clumsy.</p>

425,618 | <p>There are essentially 2 places to define JavaScript functions in Grails, directly in a element on the GSP, and within a separate javascript source file under /web-app/js (for example, application.js). We have defined a commonly reused javascript function within application.js, but we also need to be able to generate parts of the function dynamically using groovy code. Unfortunately, ${some groovy code} does not appear to be processed within separate javascript source files.</p>
<p>Is the only way to do this by defining the javascript function within a script tag on a GSP page, or is there a more general solution? Obviously we could define the javascript function in a script tag within a template GSP file which would be reused, but there is a lot of push to keep our javascript functions defined all together in one place (i.e. the external javascript source file). This has performance benefits as well (the javascript source files are usually just downloaded once by each client's browser, instead of reloading the same javascript functions within the source of every html page they visit). I have toyed around with the idea of breaking the function up into static and dynamic pieces, putting the static ones in the external source and putting the dynamic ones in the template GSP, then gluing them together, but this seems like an unnecessary hack.</p>
<p>Any ideas?</p>
<p>(edit: It may sound like the idea of dynamically generating parts of a JavaScript function, which is then downloaded once and used over and over again by the client, would be a bad idea. However, the piece which is "dynamic" only changes perhaps once a week or month, and then only very slightly. Mostly we just want this piece generated off the database, even if only once, instead of hard coded.)</p>

425,634 | <p>(I still feel like a complete newbie in MS Visual environments... so please bear with!)</p>
<p>I'm using Microsoft Visual C# 2008 Express Edition.</p>
<p>I have a project and in that project are two different forms. The .cs file for each form starts out:</p>
<pre><code>using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Data.Common;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
namespace MyNameSpace
{
public partial class MyFormName : Form
{
...
</code></pre>
<p>(...and the second is "MyFormName2" but no differences besides that)</p>
<p>I want to write a function that I know both forms are going to need to access. I right-clicked on my project, selected "Add", selected "New Item" then selected "Code File" and named my file "Common.cs" and it gave me a completely blank file that's in my project.</p>
<p>How do I set this up...? I thought I should do the following...</p>
<pre><code>using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Data.Common;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
namespace MyNameSpace
{
}
</code></pre>
<p>...but then when I try to add a function like:</p>
<p>public void mytestfunc() {
}
within that namespace I get the following error: </p>
<p>"Expected class, delegate, enum, interface, or struct"</p>
<p>How do I set things up so I can have "mytestfunc" be available to both MyFormName and MyFormName2?</p>
<p>Thanks!</p>
<p>-Adeena</p>
<p>UPDATE:
Understand (now) that everything must be in a class, but then I don't understand how to really use it. Does that mean I have to create an object? This common function happens to just be some math... </p>
<p>so now if I have this:</p>
<pre><code>namespace MyNameSpace
{
public class MyCommonClass
{
public void testFunc()
{
MessageBox.Show("Hee hee!");
return;
}
}
}
</code></pre>
<p>...how do I call testFunc from my Form? Must I do the following:</p>
<pre><code>MyCommonClass temp = new MyCommonClass;
temp.testFunc();
</code></pre>
<p>or is there another way to call testFunc?</p>

425,661 | <p>In the modern era of CSS, how would I create a pair of panels (for example, a preview window like in Outlook, or for master/detail views)? Ideally where the top (master) pane would get scrollbars, etc.?</p>
<p>The intended use-case is so that a user can scroll in the top window while always being able to see the preview / detail window (I intend to load data for the selected row into the bottom panel via jQuery).</p>
<p>In the old world (table layouts), I might have something like:</p>
<pre><code><html>
<body>
<table height="100%" border="1" width="100%">
<tr height="*"><td>master</td></tr>
<tr height="100"><td>detail</td></tr>
</body>
</html>
</code></pre>
<p>So how does this translate to CSS? (and in particular, getting the scrollbars on the two windows).</p>

425,680 | <p>Is there a pattern where in WPF, I can build a simple UI form from an XML like definition file pulled from a database? </p>
<p>It would allow the user to enter data into this form, and submit it back. The data would be sent back in an XML structure that would closely/exactly mimic the UI definition. </p>
<p>The definition should include the data-type, and if it was a required value or not. I would then like to map these data-types and required values to Data Validation Rules, so the form could not be submitted unless it passes the check. </p>
<p>It should also handle the ability to have lists of repeating data.</p>
<p>I am in the planning stages of this project and have fairly good flexibility in the design at this point, though I am pretty sure I need to stick to the desktop, not web since I may be doing some Office Inter-op stuff as well.</p>
<p>What technology stack would you recommend? I think XMAL and WPF may be close to the answer. </p>
<p>I have also looked at <a href="http://www.mozilla.org/projects/xul" rel="nofollow noreferrer">XUL</a>, but it doesn't seem ready or useful for C#. (Found this <a href="http://msdn.microsoft.com/en-us/magazine/cc188912.aspx" rel="nofollow noreferrer">article</a> from MSDN in 2002)</p>

425,692 | <p>I'm beginning a new project in PHP and I'd love to get some feedback from other developers on their preferred strategy for PHP deployment. I'd love to automate things a bit so that once changes are committed they can be quickly migrated to a development or production server.</p>
<p>I have experience with deployments using Capistrano with Ruby as well as some basic shell scripting.</p>
<p>Before I dive head first on my own it would be great to hear how others have approached this in their projects.</p>
<h2>Further information</h2>
<p>Currently developers work on local installations of the site and commit changes to a subversion repository. Initial deployments are made by exporting a tagged release from svn and uploading that to the server.</p>
<p>Additional changes are typically made piecemeal by manually uploading changed files.</p>

425,709 | <p>Lots of developers think that testing private methods is a bad idea. However, all examples I've found were based on the idea that private methods are private because calling them could break internal object's state. But that's not only reason to hide methods.</p>
<p>Let's consider Facade pattern. My class users need the 2 public methods. They would be too large. In my example, they need to load some complex structure from the database's BLOB, parse it, fill some temporary COM objects, run user's macro to validate and modify these objects, and serialize modified objects to XML. Quite large functionality for the single metod :-) Most of these actions are required for both public methods. So, I've created about 10 private methods, and 2 public methods do call them. Actually, my private methods should not necessarily be private; they'll not break the internal state of instance. But, when I don't wont to test private methods, I have the following problems:</p>
<ol>
<li>Publishing them means complexity for users (they have a choice they don't need) </li>
<li>I cannot imagine TDD style for such a large public methods, when you're to write 500+ lines of code just to return something (even not real result). </li>
<li>Data for these methods is retrieved from database, and testing DB-related functionality is much more difficult.</li>
</ol>
<p>When I'm testing private methods:</p>
<ol>
<li>I don't publish details that would confuse users. Public interface includes 2 methods.</li>
<li>I can work in TDD style (write small methods step-by-step). </li>
<li>I can cover most of class's functionality using test data, without database connection.</li>
</ol>
<p>Could somebody describe, what am I doing wrong? What design should I use to obtain the same bonuses and do not test private methods?</p>
<p>UPDATE: It seems to me I've extracted everything I was able to another classes. So, I cannot imagine what could I extract additionally. Loading from database is performed by ORM layer, parsing stream, serializing to XML, running macro - everything is done by standalone classes. This class contains quite complex data structure, routines to search and conversion, and calls for all mentioned utilities. So, I don't think something else could be extracted; otherwise, its responsibility (knowledge about the data structure) would be divided between classes.</p>
<p>So, the best method to solve I see now is dividing into 2 objects (Facade itself and real object, with private methods become public) and move real object to somewhere nobody would try to find it. In my case (Delphi) it would be a standalone unit, in other languages it could be a separate name space. Other similar option is 2 interfaces, thanks for idea.</p>

425,711 | <p>I have medium sized MySQL database with a primary "persons" table which contains basic contact information about every human being connected to the theatre and theatre school for which I am responsible for maintaining and developing a number of web applications.</p>
<p>Some persons are just contacts - that is, their "persons" table record is all the information we need to store about them. Many others though have to be able to assume different roles for a variety of systems. Of these, most start out as students. Some start as employees. People who are students can become interns or performers; employees can become students; all teachers are employees and performers, etc.</p>
<p>In essence, their are a variety of different "hats" that any individual person may have to wear in order to access and interact with different parts of the system, as well as have information about them made available on public pages on our site.</p>
<p>My choice for implementing this model is to have several other tables which represent these "hats" - tables which contain meta-information to supplement the basic "person" info, all of which use the "persons" id as their primary key. For example, a person who is a teacher has a record in a teachers table containing his or her short biographical information and pay rate. All teachers are also employees (but not all employees are teachers), meaning they have a record in the employees table which allows them to submit their hours into our payroll system.</p>
<p>My question is, what are the drawbacks to implementing the model as such? The only other option I can think of is to inflate the persons table with fields that will be empty and useless for most entries and then have a cumbersome table of "groups" to which persons can belong, and then to have almost every table for every system have a person <code>person_id</code> foreign key and then depend on business logic to verify that the person_id referenced belongs to the appropriate group; But that's stupid, isn't it?</p>
<p>A few example table declarations follow below, which hopefully should demonstrate how I'm currently putting all this together, and hopefully show why I think it is a more sensible way to model the reality of the various situations the systems have to deal with.</p>
<p>Any and all suggestions and comments are welcome. I appreciate your time.</p>
<p><strong>EDIT</strong> A few respondents have mentioned using ACLs for security - I did not mention in my original question that I am in fact using a separate ACL package for fine-grained access control for actual users of the different systems. My question is more about the best practices for storing metadata about people in the database schema. </p>

425,805 | <p>One of the things I'm doing includes several links on the <strong>show</strong> view. For instance, I have a link (or button) for "Accepting", and another one for "Rejecting". Click on Accept, and the model updates the is_accepted field as true, click on Reject, and the is_accepted field is false.</p>
<p>Now, how best do I handle this? In ASP.NET, I would have simply created a LinkButton and written a handler, but Rails doesn't work that way, so I'm trying to figure out how to essentially replicate what a LinkButton would do. </p>
<p>Right now, I'm coding two forms on the same view, nearly identical, that look like this:</p>
<pre><code><%= form_for @thing do |f| %>
<%= hidden_field_tag 'thing[is_accepted]', '1' %>
<%= f.submit "Accept" %>
<% end %>
<%= form_for @thing do |f| %>
<%= hidden_field_tag 'thing[is_accepted]', '0' %>
<%= f.submit "Reject" %>
<% end %>
</code></pre>
<p>This feels weird to me, but I can't seem to find anything that says this is the wrong way to do it.</p>
<p>I could, I assume, dry things up by using a partial and/or a helper method, but I wanted to make sure I'm on the right track and not doing something totally wrongly.</p>

425,809 | <p>We are having trouble with a Java web application running within Tomcat 6 that uses JDBC to connect to a SQL Server database.</p>
<p>After a few requests, the application server dies and the in the log files we find exceptions related to database connection failures.</p>
<p>We are not using any connection pooling right now and we are using the standard JDBC/ODBC/ADO driver bridge to connect to SQL Server.</p>
<p>Should we consider using connection pooling to eliminate the problem?</p>
<p>Also, should we change our driver to something like jTDS?</p>

425,814 | <p>In my C# application, I use a regular expression to validate the basic format of a US phone number to make sure that the user isn't just entering bogus data. Then, I strip out everything except numbers, so this:</p>
<blockquote>
<p>(123) 456-7890 x1234</p>
</blockquote>
<p>becomes</p>
<blockquote>
<p>12345678901234</p>
</blockquote>
<p>in the database. In various parts of my application, however, I would like to convert this normalized phone number back to</p>
<blockquote>
<p>(123) 456-7890 x1234</p>
</blockquote>
<p>What's the best way to do such a thing? (Don't worry about accounting for international phone number formats, by the way.)</p>

425,864 | <p>I have a bat file that I should use to delete a part of one file and save into another one. I need to delete all the symbols between text "[aaa bbb]" and "[ccc ddd]". That is if I have the text:</p>

1
2
3
[ccc ddd]
</code></pre>
<p>I should have as output:</p>
<pre><code>[aaa bbb]
[ccc ddd]
</code></pre>
<p>Thank you</p>
<p><strong>EDIT:</strong> I would like to clarify the question. I should delete all the symbols between marker1 and marker2. Marker1 and marker2 are just some words or parts of text but not obligatory lines. For example I would have:</p>
<pre><code>[aaa bbb] [ccc]
1
2
3
4
5
[www yyy]
</code></pre>
<p>If I want to delete the text between [aaa bbb] and [www yyy] I should have as output:</p>
<pre><code>[aaa bbb]
[www yyy]

425,867 | <p>I'm having trouble using the flowlayoutPanel in a C# winform application. What I basically have is a flow layout panel that has 3 sections.</p>
<p>Section #1 is a set of 2 controls .. two dropdown controls, they are always in the same order, always visible in all instances</p>
<p>Section #2 is a set of 5 different controls ... based on a series of factors, 1 of the 5 controls is made visible, all others have the Visible propert set to false</p>
<p>Section #3 is a set of 3 controls .. like Section #1 they are always in the same order and always visible.</p>
<p>So what this boils down to is that Section #2 is variable, the others are static.</p>
<p>The problem comes with Section #2 ... when I change the visibility of any of the controls they appear just fine (I.E. ... Section 1 then Section 2 then Section 3) ... EXCEPT when I set the combobox control to be Visible .... in that case, and ONLY in that case .. the order becomes (Section 1 then Section 3 then Section 2) ... I can't figure out what would cause the ordering to be out of sync in just that case.</p>
<p>What I basically do at the beginning of my method is set ALL controls to Visible = false ... then I set Section 1 Visible = true ... then loop through the conditions of Section 2 and set the appropriate controls Visible = true and finally set Section 3 controls Visible = true.</p>
<p>Does anyone have any experience with the flow layout panel control ordering? I can't figure out what is happening for the ComboBox.</p>

425,870 | <p>I'm trying to call a stored procedure (on a SQL 2005 server) from C#, .NET 2.0 using <code>DateTime</code> as a value to a <code>SqlParameter</code>. The SQL type in the stored procedure is 'datetime'.</p>
<p>Executing the sproc from SQL Management Studio works fine. But everytime I call it from C# I get an error about the date format. </p>
<p>When I run SQL Profiler to watch the calls, I then copy paste the <code>exec</code> call to see what's going on. These are my observations and notes about what I've attempted:</p>
<p>1) If I pass the <code>DateTime</code> in directly as a <code>DateTime</code> or converted to <code>SqlDateTime</code>, the field is surrounding by a PAIR of single quotes, such as</p>
<pre><code>@Date_Of_Birth=N''1/8/2009 8:06:17 PM''
</code></pre>
<p>2) If I pass the <code>DateTime</code> in as a string, I only get the single quotes</p>
<p>3) Using <code>SqlDateTime.ToSqlString()</code> does not result in a UTC formatted datetime string (even after converting to universal time)</p>
<p>4) Using <code>DateTime.ToString()</code> does not result in a UTC formatted datetime string.</p>
<p>5) Manually setting the <code>DbType</code> for the <code>SqlParameter</code> to <code>DateTime</code> does not change the above observations.</p>
<p>So, my questions then, is how on earth do I get C# to pass the properly formatted time in the <code>SqlParameter</code>? Surely this is a common use case, why is it so difficult to get working? I can't seem to convert <code>DateTime</code> to a string that is SQL compatable (e.g. '2009-01-08T08:22:45')</p>
<p><strong>EDIT</strong></p>
<p>RE: BFree, the code to actually execute the sproc is as follows:</p>
<pre><code>using (SqlCommand sprocCommand = new SqlCommand(sprocName))
{
sprocCommand.Connection = transaction.Connection;
sprocCommand.Transaction = transaction;
sprocCommand.CommandType = System.Data.CommandType.StoredProcedure;
sprocCommand.Parameters.AddRange(parameters.ToArray());
sprocCommand.ExecuteNonQuery();
}
</code></pre>
<p>To go into more detail about what I have tried:</p>
<pre><code>parameters.Add(new SqlParameter("@Date_Of_Birth", DOB));
parameters.Add(new SqlParameter("@Date_Of_Birth", DOB.ToUniversalTime()));
parameters.Add(new SqlParameter("@Date_Of_Birth",
DOB.ToUniversalTime().ToString()));
SqlParameter param = new SqlParameter("@Date_Of_Birth",
System.Data.SqlDbType.DateTime);
param.Value = DOB.ToUniversalTime();
parameters.Add(param);
SqlParameter param = new SqlParameter("@Date_Of_Birth",
SqlDbType.DateTime);
param.Value = new SqlDateTime(DOB.ToUniversalTime());
parameters.Add(param);
parameters.Add(new SqlParameter("@Date_Of_Birth",
new SqlDateTime(DOB.ToUniversalTime()).ToSqlString()));
</code></pre>
<p><strong>Additional EDIT</strong></p>
<p>The one I thought most likely to work:</p>
<pre><code>SqlParameter param = new SqlParameter("@Date_Of_Birth",
System.Data.SqlDbType.DateTime);
param.Value = DOB;
</code></pre>
<p>Results in this value in the exec call as seen in the SQL Profiler</p>
<pre><code>@Date_Of_Birth=''2009-01-08 15:08:21:813''
</code></pre>
<p>If I modify this to be:</p>
<pre><code>@Date_Of_Birth='2009-01-08T15:08:21'
</code></pre>
<p>It works, but it won't parse with pair of single quotes, and it wont convert to a <code>DateTime</code> correctly with the space between the date and time and with the milliseconds on the end.</p>
<p><strong>Update and Success</strong></p>
<p>I had copy/pasted the code above after the request from below. I trimmed things here and there to be concise. Turns out my problem was in the code I left out, which I'm sure any one of you would have spotted in an instant. I had wrapped my sproc calls inside a transaction. Turns out that I was simply not doing <code>transaction.Commit()</code>!!!!! I'm ashamed to say it, but there you have it.</p>
<p>I still don't know what's going on with the syntax I get back from the profiler. A coworker watched with his own instance of the profiler from his computer, and it returned proper syntax. Watching the very SAME executions from my profiler showed the incorrect syntax. It acted as a red-herring, making me believe there was a query syntax problem instead of the much more simple and true answer, which was that I need to commit the transaction! </p>
<p>I marked an answer below as correct, and threw in some up-votes on others because they did, after all, answer the question, even if they didn't fix my specific (brain lapse) issue.</p>

425,902 | <p>I have a sprite that I do some custom drawing in, but I would like the container to know where to position the sprite properly.

<p><strong>Edit:</strong> I'm doing the drawing in Event.ENTER_FRAME, and it's animated, so I can't tell ahead of time how big it's going to be. The UIComponent has a measure function and I'd like to create something similar.</p>

425,975 | <p>Our I.T. dept doesn't allow connections to the SVN server from outside the physical office. (They're just kind of like that.) I need to work on projects when I'm not at the office.</p>
<p>I could just check out the project and wait until I come in to do a check-in. Maybe that would be best. But I like to check in frequently. I'm wondering if there's some way I can keep a project in two repositories and keep them both up to date. That way I'd always be able to check in somewhere in case my HD dies. I have my own repository on a VPS server that I use for personal projects.</p>
<p>I investigated the <code>svn switch</code> command. With my current project in both repos I tried switching my working copy from personal to work SVN servers...</p>
<pre><code>$ svn switch --relocate svn+ssh://personalvps.com/svn/project/trunk svn://worksvn/project/trunk
svn: The repository at 'svn://worksvn/project/trunk' has uuid '2baef97e-42ce-488c-bbba-c2625158c643', but the WC has 'f13e1f32-dc92-4c4a-b84d-34a59fe32063'
</code></pre>
<p>Then I tried adding the <code>--username</code> and <code>--password</code> params but got an error saying "no entry found."</p>
<p>Is this even possible or is it totally impractical?</p>

<p>Thanks for the answers. Unfortunately, any solution that involves action from I.T. (slight policy change, change a setting somewhere, install something) is not on the table. I have to find a solution within the current setup, which is no connections from outside except our Web servers.</p>
<p>I'll take a look at distributed version control.</p>

425,987 | <p>Currently i am working on a desktop application which consists mathematical analysiss.I am using qt for GUI and project written in c++.
When user starts an analysis, i open a worker thread and start a progress bar.Everything is ok up to now, problem starts when user cancels operation.Operation is complex, i am using several functions and objects, i allocate/deallocate memory at several times.I want to learn what should i do for recovering in cancel operation.Because there can be memory leaks.Which pattern or method i should use to be robust and safe for cancelling operation?</p>
<p>My idea is throwing an exception, but operation is really complex so should i put try-catch to all of my functions or is there a more generic way, pattern..</p>
<p>Edit: Problem is my objects are transfered between scopes, so shared_ptr or auto_ptr doesnt solve my problem,
Flag idea can be, but i think it requires so much code and there should be an easy way.</p>

425,988 | <p>Does anyone happen to know what the maximum length of a method name is in your programming language of choice? I was going to make this a C# specific question, but I think it would be nice to know across the spectrum.</p>
<p>What are the factors involved as well:</p>
<ul>
<li>Does the language specification limit this?</li>
<li>What does the compiler limit it to?
<ul>
<li>Is it different on 32bit vs 64bit machines?</li>

426,041 | <p>I've been following Miguel Castro's excellent article on WCF <a href="http://www.devx.com/codemag/Article/39837" rel="noreferrer">here</a> and it's all working nicely, except that I have the following code</p>
<pre><code>public AdminClient()
{
ChannelFactory<IProductAdmin> factory = new ChannelFactory<IProductAdmin>();
productAdminChannel = factory.CreateChannel();
}
</code></pre>
<p>In my app.config file, I have the following configuration:</p>
<pre><code><system.serviceModel>
<client>
<endpoint address="net.tcp://localhost:8002/ProductBrowser"
binding="netTcpBinding"
contract="Contracts.IProductAdmin" />
</client>
</system.serviceModel>
</code></pre>
<p>But, when I run the constructor for AdminClient I get an exception saying that the endpoint isn't defined. However, if I change my configuration to give the endpoint a name, and then create the factory as follows, it works. </p>
<pre><code>public AdminClient()
{
var fac = new ChannelFactory<IProductAdmin>("admin");
productAdminChannel = fac.CreateChannel();
}
</code></pre>
<hr>
<pre><code><system.serviceModel>
<client>
<endpoint name="admin"
address="net.tcp://localhost:8002/ProductBrowser"
binding="netTcpBinding"
contract="Contracts.IProductAdmin" />
</client>
</system.serviceModel>
</code></pre>
<p>I'd love an explanation for this. The documentation in MSDN isn't much help...</p>

426,071 | <p>I have several servers hosted with GoGrid, and every time I reboot one of my cloud servers, the system clock is incorrect. The server isn't a member of a domain, so I just have the OS set to sync with an Internet time server. This only happens once a day, and I don't see an option to make this happen automatically upon reboot. So I'm left with writing some code to do it for me.</p>
<p>I created a batch file with the "w32tm /resync" command, and scheduled it to run on system startup, but it doesn't work because the network connection isn't available when the batch file is run. How can I cause the time sync to start after the OS is fully loaded and the network connection is available? I need the time to be correct ASAP after the computer boots so timestamps in my database will be correct.</p>

426,081 | <p>When viewing (or editing) a .gz file, vim knows to locate gunzip and display the file properly.<br>
In such cases, getfsize(expand("%")) would be the size of the gzipped file. </p>
<p>Is there a way to get the size of the expanded file?</p>
<p>[EDIT]<br>
Another way to solve this might be getting the size of current buffer, but there seems to be no such function in vim. Am I missing something?</p>

426,110 | <p>As described in <a href="http://www.asp.net/Learn/mvc/tutorial-13-cs.aspx" rel="nofollow noreferrer">this post</a>, I created an abstract base controller class in order to be able to pass data from a controller to master.page. In this case, I want to lookup a user in my db, querying for User.Identity.Name (only if he is logged in).</p>
<p>However, I noticed that in this abstract base class the <code>User</code> property is always <code>null</code>. What do I have to do to get this working?</p>

426,128 | <p>I'm pulling a list of items from one table, on the basis of their being included in another table, like this:</p>
<pre><code>select fruit.id, fruit.name from fruit, fruit_rating where fruit_rating.fruit_id=fruit.id group by fruit.name;
</code></pre>
<p>That works fine -- it basically produces a list of all the fruit that has been rated by someone. But now, I want to exclude all fruit that has been rated by one specific user, so I tried this:</p>
<pre><code>select fruit.id, fruit.name from fruit, fruit_rating where fruit_rating.fruit_id=fruit.id and fruit_rating.user_id != 10 group by fruit.name;
</code></pre>
<p>That's ok, but not quite right. It shows all the fruit that have been rated by people other than 10, but if users 1 and 10 have both rated the same fruit, it still shows that one. Can anyone tell me how to construct a query that shows only the fruit that have NOT Been rated by user 10, regardless of who else has rated them?</p>

426,162 | <p>I'm writing a simplistic game to learn get some more C++ experience, and I have an idea where I feel polymorphism <em>almost</em> works, but doesn't. In this game, the <code>Party</code> moves fairly linearly through a <code>Map</code>, but can occasionally encounter a <code>Fork</code> in the road. A fork is (basically) an <code>std::vector<location*></code>.Originally I was going to code something like the following into the a <code>Party</code> member function:</p>
<pre><code>if(!CurrLocation->fork_.empty())
// Loop through forks and show options to the player, go where s/he wants
else
(CurrLocation++)
</code></pre>
<p>But I was wondering if some variant of the following might be better:</p>
<pre><code>CurrLocation = CurrLocation->getNext();
</code></pre>
<p>With Fork actually being derived from Location, and overloading some new function <code>getNext()</code>. But in the latter case, the <code>location</code> (a low level structure) would have to be the one to present the message to the user instead of "passing this back up", which I don't feel is elegant as it couples <code>location</code> to <code>UserInterface::*</code>.</p>
<p>Your opinions?</p>

426,173 | <p>Here is my problem. Imagine I am buying 3 different items, and I have up to 5 coupons. The coupons are interchangeable, but worth different amounts when used on different items.</p>
<p>Here is the matrix which gives the result of spending different numbers of coupons on different items:</p>
<pre><code>coupons: 1 2 3 4 5
item 1 $10 off $15 off
item 2 $5 off $15 off $25 off $35 off
item 3 $2 off
</code></pre>
<p>I have manually worked out the best actions for this example:</p>
<ul>
<li>If I have 1 coupon, item 1 gets it for $10 off</li>
<li>If I have 2 coupons, item 1 gets them for $15 off</li>
<li>If I have 3 coupons, item 1 gets 2, and item 3 gets 1, for $17 off</li>
<li>If I have 4 coupons, then <strong>either</strong>:
<ul>
<li>Item 1 gets 1 and item 2 gets 3 for a total of $25 off, or</li>
<li>Item 2 gets all 4 for $25 off.</li>
</ul></li>
<li>If I have 5 coupons, then item 2 gets all 5 for $35 off.</li>
</ul>
<p>However, I need to develop a general algorithm which will handle different matrices and any number of items and coupons.</p>
<p>I suspect I will need to iterate through every possible combination to find the best price for <em>n</em> coupons. Does anyone here have any ideas?</p>

<p>I would like to push this file to be downloaded through the browser onto the client, and opened using whatever application is default for this file type. I really don't want to save the blob as a file on the server; that will leave a terrible housekeeping mess that I just don't want to think about.</p>
