<p>Any channel already around that people are using?</p>

288,441 | <p>I long thought that in C, all variables had to be declared at the beginning of the function. I know that in C99, the rules are the same as in C++, but what are the variable declaration placement rules for C89/ANSI C?</p>
<p>The following code compiles successfully with <code>gcc -std=c89</code> and <code>gcc -ansi</code>:</p>
<pre><code>#include <stdio.h>
int main() {
int i;
for (i = 0; i < 10; i++) {
char c = (i % 95) + 32;
printf("%i: %c\n", i, c);
char *s;
s = "some string";
puts(s);
}
return 0;
}
</code></pre>
<p>Shouldn't the declarations of <code>c</code> and <code>s</code> cause an error in C89/ANSI mode?</p>

288,465 | <p>I'm building an XML DOM document in C++. My problem is this: I execute an XPATH query from an Element in my Document, which I know will return another Element. The elementPtr->selectSingleNode call returns an IXMLDOMNode. How can I gain access to the attributes of this node?</p>
<p>Part of me wants to downcast the Node to an Element, but I couldn't get the cast to work.</p>
<p>I tried</p>
<pre><code>MSXML2::IXMLDOMElementPtr pParentElement;
pParentNode->QueryInterface(__uuidof(MSXML2::IXMLDOMElement),
(void**) &pParentElement);
</code></pre>
<p>Which results in the following runtime error: </p>
<pre><code>0x0057cc58 _com_error::`scalar deleting destructor'(unsigned int)
</code></pre>
<p>The other route I tried was to just use nodes:</p>
<pre><code>MSXML2::IXMLDOMNodePtr pParentNode =
pParameterElement->selectSingleNode("parent");
MSXML2::IXMLDOMNamedNodeMap* pParentAttributes;
pParentNode->get_attributes(&pParentAttributes);
MSXML2::IXMLDOMNodePtr pCategoryNameNode =
pParentAttributes->getNamedItem("Category");
VARIANT value;
pCategoryNameNode->get_nodeValue(&value);
CString categoryName = value;
</code></pre>
<p>This fails at "parentNode->get_attributes()".</p>
<p>It seems like I'm missing something; the API should not be this hard to use.</p>
<p>--edit--</p>
<p>What I was missing was that the selectSingleNode call was failing, leaving me with a NULL pointer. You can't call QueryInterface on that, neither can you call get_attributes on it :P</p>
<p>I've selected the answer that fits the question that I asked, not the answer that helped me to realise that I asked the wrong question.</p>

288,500 | <p>I am having an issue with SSH hanging on my Mac Book Pro. This only happens to me once I get home from work after I have used SSH while at work. The three factors I have narrowed the issue down to are SSH, our work AFS network drive and the method of network connectivity.</p>
<p>At work we use an AFS drive with Kerberos Authentication to do all of our software development work on. I authenticate with Kerberos in order to gain access to the AFS drive where all my source code lives, but I open a local editor (Eclipse) which references the files on the AFS drive. Whenever I need to compile my code, I SSH in to my development server (which is also authenticated to the AFS drive) and compile from there. (Sanity Note: I know that it is a super wacky setup, but I promise I had NOTHING to do with it. I'm just making do with what I've got.)</p>
<p>For my Network Preferences, I use the Automatic location all the time. For that configuration I have Built-in Ethernet en1 configured to use DHCP and our company's DNS server for when I'm at work (there is no wireless available). When I go home I connect to my home network via wireless, again using DHCP.</p>
<p>I have a hunch that the AFS connection/Ethernet configuration is somehow the culprit here. Restarting the SSH daemon doesn't correct the problem. The only way I have found to correct the issue is by restarting the computer each time I want to use SSH. Keep in mind that I have no other (known) networking issues while at home after I've had the laptop at work. </p>
<p>I have a co-worker who has reported to me the same issue on his MBP.</p>
<p>I'm truly stumped on this one. Please provide some guidance. Thanks! </p>

288,513 | <p>Here is what I am trying to do:
Given a date, a day of the week, and an integer <code>n</code>, determine whether the date is the <code>n</code>th day of the month.</p>
<p>For example:</p>
<ul>
<li><p>input of <code>1/1/2009,Monday,2</code>
would be false because <code>1/1/2009</code> is not the second Monday</p></li>
<li><p>input of
<code>11/13/2008,Thursday,2</code>
would return true because it is the second Thursday</p></li>
</ul>
<p>How can I improve this implementation?</p>
<pre><code>private bool NthDayOfMonth(DateTime date, DayOfWeek dow, int n)
{
int d = date.Day;
return date.DayOfWeek == dow && (d/ 7 == n || (d/ 7 == (n - 1) && d % 7 > 0));
}
</code></pre>

288,546 | <p>I need to connect to an Exchange mailbox in a Python script, without using any profile setup on the local machine (including using Outlook). If I use win32com to create a MAPI.Session I could logon (with the Logon() method) with an existing profile, but I want to just provide a username & password.</p>
<p>Is this possible? If so, could someone provide example code? I would prefer if it only used the standard library and the pywin32 package. Unfortunately, enabling IMAP access for the Exchange server (and then using imaplib) is not possible.</p>
<p>In case it is necessary: all the script will be doing is connecting to the mailbox, and running through the messages in the Inbox, retrieving the contents. I can handle writing the code for that, if I can get a connection in the first place!</p>
<p>To clarify regarding Outlook: Outlook will be installed on the local machine, but it does not have any accounts setup (i.e. all the appropriate libraries will be available, but I need to operate independently from anything setup inside of Outlook).</p>

288,550 | <p>How can I create a Sidebar form in delphi.</p>
<p>I try the <code>ScreenSnap</code> and <code>Align</code> properties but I need that the form stay visible even if the user maximize other forms, without been on top. Just like the windows sidebar do.</p>
<p><strong>Update</strong>: From the comments: if a window is maximized, it maximizes next to the window, not in front of or behind.</p>

288,559 | <p>Even though error_reporting is set to 0, database errors are still being printed to screen. Is there a setting somewhere I can change to disable database error reporting? This is for CodeIgniter v1.6.x</p>
<p><strong>EDIT</strong>: Re: Fixing errors - Um, yes. I want to fix the errors. I get error notices from my error log, not from what my visitors see printed to their screen. That helps no one, and hurts my system's security.</p>
<p><strong>EDIT 2</strong>: Setting error_reporting to 0 does not affect CodeIgniter's built-in error logging class from writing to the error log.</p>

288,575 | <p>I inherited a project that uses SQL Server 200x, wherein a column that stores a value that is always considered as a percentage in the problem domain is stored as its greater than 1 decimal equivalent. For example, <em>70%</em> (0.7, literally) is stored as <em>70</em>, <em>100%</em> as <em>100</em>, etc. Aside from the need to remember to * 0.01 on retrieved values and * 100 before persisting values, it doesn't seem to be a problem in and of itself. <strike>It does make my head explode though</strike>... so is there a good reason for it that I'm missing? Are there compelling reasons to fix it, given that there is a fair amount of code written to work with the pseudo-percentages?</p>
<p>There are a few cases where greater than 100% occurs, but I don't see why the value wouldn't just be stored as 1.05, for example, in those cases.</p>
<p>EDIT: Head feeling better, and slightly smarter. Thanks for all the insights.</p>

288,582 | <p>Here's the scenario - a client uploads a Sybase dump file to (gzipped) to our local FTP server. We have an automated process which picks these up and then moves them to different server within the network where the database server resides. Unfortunately, this transfer is over a WAN, which for large files takes a long time, and sometimes our clients forget to FTP in binary mode, which results in 10GB of transfer over our WAN all for nothing as the dump file can't be loaded at the other end. What I'd like to do, is verify the integrity of the dump file on the local server before sending it out over the WAN, but I can't just try and "load" the dump file, as we don't have Sybase installed (and can't install it). Are there any tools or bits of code that I can use to do this?</p>

288,584 | <p>I want to use <a href="http://code.google.com/apis/visualization/documentation/gallery/annotatedtimeline.html" rel="nofollow noreferrer">Google's Annotated Time Line Visualization</a>. It is very easy to make this work by manually adding the lines for column & row data. This is all done through attributes of google.visualization.DataTable(). I would like to update this data table dynamically, but I do not know how. The data is on a server running MS SQL Server 2005. </p>
<p>I found a <a href="http://groups.google.com/group/google-visualization-api/browse_thread/thread/4dc84221fbd3ade5/d57109c9b45fd741?lnk=raot&pli=1" rel="nofollow noreferrer">post</a> to accomplish this with PHP and MySQL, but I do not know how to translate this to VB .NET or C# (either is fine).</p>
<p>Does anyone know how to make this use MS SQL Server data in .NET or of a better way to have the code dynamically generated so new data does not have to have the lines manually added every day?</p>
<p>Thanks!</p>

288,603 | <p>I am getting </p>
<pre><code>Warning: mysql_fetch_assoc(): supplied argument is not a valid MySQL result
resource in *filename* on line 81
</code></pre>
<p>While running a query to build a chart. The query gets data from the mysql db and uses it to build the chart.</p>
<p>Usually, I get this error and go to the code and find where I've screwed up, fix it, and move on. The tricky part about this problem is that the query is actually running and the chart is being built and displayed accurately. Why is my server (localhost on xampp) telling me that the query result is bad when it can utilize the resource just fine?</p>
<p>Here is the full query:</p>
<pre><code>$chart=array();
$roll=array();
//select used terms
$rosh=mysql_query("select distinct term from search_terms");
while($roshrow=mysql_fetch_assoc($rosh)){
extract($roshrow);
$roll[]=$term;
}
//select term_number for each term
foreach($roll as $sterm){
$termarray=array();
**//following is line 81**
$bashq="select term_number from search_terms where term ='$sterm'";
$bash=mysql_query($bashq);
while($brow=mysql_fetch_assoc($bash)){
extract($brow);
//put results into array to sum
$termarray[]=$term_number;
}
$termsum=array_sum($termarray);
//put term=>number array for chart script
$chart[$sterm]=$termsum;
}
//sort array so high numbers at beginning
arsort($chart);
//slice top 10 terms
$chart=array_slice($chart,0,10);

288,619 | <p>Say I have a sql query </p>
<pre><code>SELECT fname, lname, dob, ssn, address1, address2, zip, phone,state from users
</code></pre>
<p>Now say the records are now either in dictionary base or a strongly typed collection.</p>
<p>I have a grid view control and i want to bind it to my collection but I only want to display fname, lname, dob and ssn and not the other columns.</p>
<p>Is there an easy way to extract the columns and then bind to the extracted item? Not sure if LINQ would be helpful here.</p>
<p>This is a test project as I am getting familiar with the web world wqith VS-2008</p>

288,637 | <p>I need to construct some rather simple SQL, I suppose, but as it's a rare event that I work with DBs these days I can't figure out the details.</p>
<p>I have a table 'posts' with the following columns:</p>
<blockquote>
<p>id, caption, text</p>
</blockquote>
<p>and a table 'comments' with the following columns:</p>
<blockquote>
<p>id, name, text, post_id</p>
</blockquote>
<p>What would the (single) SQL statement look like which retrieves the captions of all posts which have one or more comments associated with it through the 'post_id' key? The DBMS is MySQL if it has any relevance for the SQL query.</p>

288,687 | <p>I've written a cheap & cheerful sound board in for my Mac, and I play the various sounds with NSSound like this:</p>
<pre><code>-(void)play:(NSSound *)soundEffect:(BOOL)stopIfPlaying {

if([nowPlaying isPlaying]) {
[nowPlaying stop];

288,695 | <p>I want to parse an Apache <strong>access.log</strong> file with a python program in a certain way, and though I am completely new to object-oriented programming, I want to start doing it now.</p>
<p>I am going to create a class <strong>ApacheAccessLog</strong>, and the only thing I can imagine now, it will be doing is '<strong>readline</strong>' method. Is it conventionally correct to inherit from the builtin <strong>file</strong> class in this case, so the class will behave just like an instance of the <strong>file</strong> class itself, or not? What is the best way of doing that?</p>

288,699 | <p>Can someone show me how to get the <code>top</code> & <code>left</code> position of a <code>div</code> or <code>span</code> element when one is not specified?</p>
<p>ie:</p>
<pre><code><span id='11a' style='top:55px;' onmouseover="GetPos(this);">stuff</span>
<span id='12a' onmouseover="GetPos(this);">stuff</span>
</code></pre>
<p>In the above, if I do:</p>
<pre><code>document.getElementById('11a').style.top
</code></pre>
<p>The value of <code>55px</code> is returned. However, if I try that for <code>span</code> '12a', then nothing gets returned.</p>
<p>I have a bunch of <code>div</code>/<code>span</code>s on a page that I cannot specify the <code>top</code>/<code>left</code> properties for, but I need to display a <code>div</code> directly under that element.</p>

288,707 | <p>I'm working with large numbers that I can't have rounded off. Using Lua's standard math library, there seem to be no convenient way to preserve precision past some internal limit. I also see there are several libraries that can be loaded to work with big numbers:</p>
<ol>
<li><a href="http://oss.digirati.com.br/luabignum/" rel="noreferrer">http://oss.digirati.com.br/luabignum/</a></li>
<li><a href="http://www.tc.umn.edu/~ringx004/mapm-main.html" rel="noreferrer">http://www.tc.umn.edu/~ringx004/mapm-main.html</a></li>

<li><a href="http://www.gammon.com.au/scripts/doc.php?general=lua_bc" rel="noreferrer">http://www.gammon.com.au/scripts/doc.php?general=lua_bc</a> (but I can't find any source)</li>
</ol>
<p>Further, there are <a href="http://en.wikipedia.org/wiki/Arbitrary-precision_arithmetic#Arbitrary-precision_software" rel="noreferrer">many libraries</a> in C that could be called from Lua, if the bindings where established.</p>
<p>Have you had any experience with one or more of these libraries?</p>

288,732 | <p>I'm working on a program that searches entire drives for a given file. At the moment, I calculate an MD5 hash for the known file and then scan all files recursively, looking for a match.</p>
<p>The only problem is that MD5 is painfully slow on large files. Is there a faster alternative that I can use while retaining a very small probablity of false positives?</p>
<p>All code is in C#.</p>
<p>Thank you.</p>
<p><strong>Update</strong></p>
<p>I've read that even MD5 can be pretty quick and that disk I/O should be the limiting factor. That leads me to believe that my code might not be optimal. Are there any problems with this approach?</p>
<pre><code> MD5 md5 = MD5.Create();
StringBuilder sb = new StringBuilder();
try
{
using (FileStream fs = File.Open(fileName, FileMode.Open, FileAccess.Read))
{
foreach (byte b in md5.ComputeHash(fs))
sb.Append(b.ToString("X2"));
}
return sb.ToString();
}
catch (Exception)
{
return "";
}
</code></pre>

288,739 | <p>I need to generate random numbers within a specified interval, [max;min].</p>
<p>Also, the random numbers should be uniformly distributed over the interval, not located to a particular point.</p>
<p>Currenly I am generating as:</p>
<pre><code>for(int i=0; i<6; i++)
{
DWORD random = rand()%(max-min+1) + min;
}
</code></pre>
<p>From my tests, random numbers are generated around one point only.</p>
<pre><code>Example
min = 3604607;
max = 7654607;
</code></pre>
<p>Random numbers generated:</p>
<pre><code>3631594
3609293
3630000
3628441
3636376
3621404
</code></pre>
<p>From answers below: OK, RAND_MAX is 32767. I am on C++ Windows platform. Is there any other method to generate random numbers with a uniform distribution?</p>

288,752 | <p>I have this strange issue with my web app. You see, I'm using jQuery with the Forms API and doing $('#MyForm').ajaxSubmit(api parms and callback function goes here).</p>
<p>Randomly when I do this, however, and only on Firefox, the page load icon starts spinning, the page load progress bar runs in the status bar, and the stop button goes red -- but it has already posted the form and brought back a result. If I refresh the page and keep trying to do this, it randomly exhibits the problem, but not consistently.</p>
<p>This problem occurred on FF2 on Windows 2008 Server and FF3 on Ubuntu 8.04. The problem is not seen with IE6, IE7, Opera (latest stable, Nov 2008), or Safari (latest stable, Nov 2008).</p>
<p>Is this just a known bug in FF with AJAX, or is there something I can do with jQuery to stop the page load issue?</p>
<p>EDIT: This <em>might</em> have something to do with TinyMCE. I cannot confirm this 100%, but when I use jQuery to bring back a form with a TinyMCE control on it, the problem seems to exhibit itself more often. I tried doing it with a form that does not have a TinyMCE control on it, several times, and couldn't get the problem to occur. Again, that's nothing conclusive, but might be a factor.</p>
<p>EDIT: Okay, I just commented out the TinyMCE stuff and I can confirm that the problem goes away then. If I bring the TinyMCE control back, the problem randomly occurs.</p>

288,775 | <p>Say I have a method that needs to pull 8 values from a map with 100 elements in it. Which do you think would be preferable:</p>
<p>Walk in a for loop from begin to end once, pulling the elements out by switching on the key?</p>
<p>Or using find 8 times to get those values?</p>

288,779 | <p>In asp.net mvc, I want to create a action for login.</p>
<p>So this is how I am doing it:</p>
<ol>
<li><p>create a action/view named login that simply displays the view.</p></li>
<li><p>create another action, named login2 that will be the page that handles the form post and checks the database if the username/password are correct. If it is, redirect to somepage, if not, redirect back to the login page with the appropriate error message.</p></li>
</ol>
<p>Is this the best way to do this?</p>

288,794 | <p>For instance, does the compiler know to translate</p>
<pre><code>string s = "test " + "this " + "function";
</code></pre>
<p>to</p>
<pre><code>string s = "test this function";

<p>and thus avoid the performance hit with the string concatenation?</p>

288,800 | <p>I have this naive regex "<([\s]|[^<])+?>" (excluding the quotation marks). It seems so
straightforward but it is indeed evil when it works against the below HTML text. It sends the Java regular expression engine to an infinite loop. </p>
<p>I have another regex ("<.+?>"), which does somewhat the same thing, but it doesn't kill anything. Do you know why this happens?</p>
<pre><code><script language="JavaScript" type="text/javascript">
var numDivs, layerName;
layerName = "lnavLayer";
catLinkName = "category";
numDivs = 2;
function toggleLayer(layerID){
if (!(navigator.appName == "Netscape" && navigator.appVersion.substr(0, 1) < 5)){
thisLayer = document.getElementById(layerName + layerID);
categoryLink = document.getElementById(catLinkName + layerID);
closeThem();
if (thisLayer.className == 'subnavDefault'){
thisLayer.className = 'subnavToggled';
categoryLink.className = 'leftnavLinkSelectedSection';
}
}
}
function closeThem(){
for(x = 0; x < numDivs; x++){
theLayer = document.getElementById(layerName + (x
+ 1));
thecategoryLink = document.getElementById(catLinkName + (x + 1));
theLayer.className = 'subnavDefault';
thecategoryLink.className = 'leftnavLink';
}
} var flag = 0; var lastClicked = 0
//-->
</script>
</code></pre>
<p>it even keeps looping with an online Java regex tool (such as <a href="http://www.fileformat.info/tool/regex.htm" rel="noreferrer">www.fileformat.info/tool/regex.htm</a>) or a utility like <a href="http://www.regexbuddy.com/" rel="noreferrer">RegexBuddy</a>.</p>

288,810 | <p>Getting the subdomain from a URL sounds easy at first.</p>
<pre><code>http://www.domain.example

<p>Scan for the first period then return whatever came after the "http://" ...</p>
<p>Then you remember</p>

<p>And you're back to square one. Anyone have any great ideas besides storing a list of all TLDs?</p>

288,813 | <p>In Delphi 2006, I am showing a modal form. User input in that form can change data that might be displayed currently on the parent form which is the mainform. To reflect those changes I need to force a repaint of some ownerdrawn components on the mainform. I tried to do that like this from the modal form:</p>
<pre><code>MainForm := Application.MainForm;
MainForm.Invalidate;
MainForm.Update;
</code></pre>
<p>That did not change a bit. I always thought an "update" on the form would always repaint it right away - apparently not so. The painting code itself should be ok since I can move the modal form over those ownerdraw components to force a manual repaint. </p>
<p>But how can I force the repaint programmatically when the data changes?</p>
<p><b>Edit:</b> I will try Application.ProcessMessages and Refresh next week, thanks for the suggestions.</p>
<p>Sorry for taking so long to answer and thanks to all who responded. Calling Refresh() was part of the solution but it had to be done on the custom draw components, not on the form they were on... Now I would like to accept more than one answer ;-)</p>

<pre><code><a href="javascript:void(0);" onclick=<% Print(); %> title="Print listings">Print</a>
</code></pre>
<p>which presents a link to print a listings to a pdf when the user clicks on it; as you can note the script calls a function from the behind code.</p>
<p>The problem is that when I coded this it happens that when I go this page it prints to pdf when is loading, I thought it would wait for a click but instead it performs the printing.</p>
<p>What is the problem? thanks in advance.</p>
<p>PD. I'm working with VS2005 and for the pdf creation I use iTextSharp.</p>

288,828 | <p>I need to test a JDBC connection to a database. The java code to do that should be as simple as:</p>
<pre><code>DriverManager.getConnection("jdbc connection URL", "username", "password");
</code></pre>
<p>The driver manager will lookup the appropriate the driver for the given connection URL. However I need to be able to load the JDBC driver (jar) at runtime. I.e I don't have the JDBC driver on the classpath of the java application that runs the snippet of code above.</p>
<p>So I can load the driver using this code, for example:</p>
<pre><code>URLClassLoader classLoader = new URLClassLoader(new URL[]{"jar URL"}, this.getClass().getClassLoader());
Driver driver = (Driver) Class.forName("jdbc driver class name", true, classLoader).newInstance();
</code></pre>
<p>But then the driver manager still won't pick it up as I can't tell it which classloader to use. I tried setting the current thread's context classloader and it still doesn't work.</p>
<p>Anyone has any idea on the best way to achieve that?</p>

288,850 | <p>I am using .Net framework 2.0 / jQuery to make an Ajax call to a 2.0 web service. No matter what I set the contentType to in the ajax call, the service always returns XML. I want it to return Json!</p>
<p>Here is the call:</p>
<pre><code> $(document).ready(function() {
$.ajax({
type: "POST",
url: "DonationsService.asmx/GetDate",
data: "{}",
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function(msg) {
// Hide the fake progress indicator graphic.
$('#RSSContent').removeClass('loading');
// Insert the returned HTML into the <div>.
$('#RSSContent').html(msg.d);
}
});
});
</code></pre>
<p>Here is what the request header looks like in Fiddler:</p>
<pre><code>POST /DonationsService.asmx/GetDate HTTP/1.1
x-requested-with: XMLHttpRequest
Accept-Language: en-us
Referer: http://localhost:1238/text.htm
Accept: application/json, text/javascript, */*
Content-Type: application/json; charset=utf-8
Accept-Encoding: gzip, deflate
User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 1.1.4322; eMusic DLM/4; .NET CLR 2.0.50727)
Host: localhost:1238
Content-Length: 2
Connection: Keep-Alive
Pragma: no-cache
</code></pre>
<p>I have tried setting the contentType to 'text/json' and get the same results.</p>
<p>Here is the web service method:</p>
<pre><code><WebMethod()> _
Public Function GetDate() As String
'just playing around with Newtonsoft.Json
Dim sb As New StringBuilder
Dim sw As New IO.StringWriter(sb)
Dim strOut As String = String.Empty
Using jw As New JsonTextWriter(sw)
With jw
.WriteStartObject()
.WritePropertyName("DateTime")
.WriteValue(DateTime.Now.ToString)
.WriteEndObject()
End With
strOut = sw.ToString
End Using
Return strOut
End Function
</code></pre>
<p>and here is what it returns:</p>
<pre><code><?xml version="1.0" encoding="utf-8"?>
<string xmlns="http://DMS.Webservices.org/">{"DateTime":"11/13/2008 6:04:22 PM"}</string>
</code></pre>
<p>Does anyone know how to force the web service to return Json when I ask for Json?</p>
<p>Please don't tell me to upgrade to .Net Framework 3.5 or anything like that (I'm not that stupid). I need a 2.0 solution.</p>

We use this as a simple context sensitive help type popup. I did a quick browse but didn't see quite what I was looking for.

<pre><code>class TestClass {

Logger::logEntry();
Logger::info('Parameter $arg => ' . $arg);

288,893 | <p>I'm using a PropertyGrid in a tool app to show a window to monitor an object in a remote app. Every second or so I get an update from the app with the state of any members that have changed, and I update the grid. I call Refresh() to make the changes take. This all works pretty well except one thing.</p>
<p>Say the object is too tall to fit in the grid so there's a scrollbar. The user has selected a grid item but has also scrolled up above it so that the selected item is below the bottom of the control.</p>
<p>The problem is that on Refresh() the control automatically scrolls the grid item into view (strangely it doesn't do this when the item is above the top of the control).</p>
<p>I'm looking for a way to either prevent this, or to save state, do the Refresh(), and then set it back. I tried getting the underlying VScrollBar in the PropertyGridView inside the PropertyGrid, and messing with "Value", but it doesn't stay permanently set. Always pops back so the item is in view.</p>
<p>Deselecting the item during scrolling is my fallback (the auto scroll-into-view doesn't happen with no selected grid item) but it hurts the usability a little so I'm looking for another way.</p>
<p>Anyone run into something similar?</p>

288,894 | <p>I have a master / detail table and want to update some summary values in the master table against the detail table. I know I can update them like this:</p>
<pre><code>update MasterTbl set TotalX = (select sum(X) from DetailTbl where DetailTbl.MasterID = MasterTbl.ID)
update MasterTbl set TotalY = (select sum(Y) from DetailTbl where DetailTbl.MasterID = MasterTbl.ID)
update MasterTbl set TotalZ = (select sum(Z) from DetailTbl where DetailTbl.MasterID = MasterTbl.ID)
</code></pre>
<p>But, I'd like to do it in a single statement, something like this:</p>
<pre><code>update MasterTbl set TotalX = sum(DetailTbl.X), TotalY = sum(DetailTbl.Y), TotalZ = sum(DetailTbl.Z)
from DetailTbl
where DetailTbl.MasterID = MasterTbl.ID group by MasterID
</code></pre>
<p>but that doesn't work. I've also tried versions that omit the "group by" clause.
I'm not sure whether I'm bumping up against the limits of my particular database (Advantage), or the limits of my SQL. Probably the latter. Can anyone help?</p>

288,900 | <p>I have a string which holds a decimal value in it and I need to convert that string into a floating point variable. So an example of the string I have is "5.45" and I want a floating point equivalent so I can add .1 to it. I have searched around the internet, but I only see how to convert a string to an integer.</p>

288,942 | <p>How to convert last 3 digits of number into 0</p>
<p>example 3444678 to 3444000</p>
<p>I can do like </p>
<p>(int)(3444678/1000) * 1000= 3444000</p>
<p>But division and multiplication could be costly...</p>
<p>Any other solution????</p>

288,954 | <p>I'm fairly new to WPF and I've come across a problem that seems a bit tricky to solve. Basically I want a 4x4 grid thats scalable but keeps a square (or any other arbitrary) aspect ratio. This actually seems quite tricky to do, which surprises me because I would imagine its a reasonably common requirement.</p>
<p>I start with a Grid definition like this:</p>
<pre><code><Grid>
<Grid.RowDefinitions>
<Grid.RowDefinition Height="*"/>
<Grid.RowDefinition Height="*"/>
<Grid.RowDefinition Height="*"/>
<Grid.RowDefinition Height="*"/>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<Grid.ColumnDefinition Width="*"/>
<Grid.ColumnDefinition Width="*"/>
<Grid.ColumnDefinition Width="*"/>
<Grid.ColumnDefinition Width="*"/>
</Grid.ColumnDefinition>
...
</Grid>
</code></pre>
<p>Now if you set that to stretch, it can fill the Window or whatever container you put it in. The rows and column are uniform but the aspect ratio isn't fixed.</p>
<p>Then I tried putting it in a StackPanel to use the available space. Didn't help. What did get me most of the way there was when I remembered Viewboxes.</p>
<pre><code><StackPanel Orientation="Horizontal">
<Viewbox>
<Grid Height="1000" Width="1000"> <!-- this locks aspect ratio -->
<Grid.RowDefinitions>
<Grid.RowDefinition Height="*"/>
<Grid.RowDefinition Height="*"/>
<Grid.RowDefinition Height="*"/>
<Grid.RowDefinition Height="*"/>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<Grid.ColumnDefinition Width="*"/>
<Grid.ColumnDefinition Width="*"/>
<Grid.ColumnDefinition Width="*"/>
<Grid.ColumnDefinition Width="*"/>
</Grid.ColumnDefinition>
...
</Grid>
</viewbox>
<Label HorizontalAlignment="Stretch">Extra Space</Label>
</StackPanel>
</code></pre>
<p>Now my content scales and keeps aspect ratio. The problem is that if the window isn't wide enough some of my grid is off the screen. I'd like to be able to scroll to it if that were the case. Likewise, I might need a minimum size, which might lead to vertical scrolling too.</p>
<p>Now I've tried putting my StackPanel and Grid (separately) in an appropriate ScrollViewer container but then the content no longer scales to fit the window. It goes to full size, which is no good.</p>
<p>So how do I go about doing this? Am I barking up the wrong tree? Is there a better/easier way of doing this?</p>

288,966 | <p>How would you describe the running time of this sort, given a function <code>sorted</code> which returns True if the list is sorted that runs in O(n):</p>
<pre><code>def sort(l):
while not sorted(l): random.shuffle(l)
</code></pre>
<p>Assume shuffling is perfectly random. </p>
<p>Would this be written in big-O notation? Or is there some other way of categorizing algorithms with random components?</p>

288,968 | <p>Is it possible to perform a named-group match in Perl's regex syntax as with Python's? I always bind the <code>$n</code> values to proper names after matching, so I'd find it more convenient to do it in the regex itself if it's possible.</p>
<p>Python does it like so:</p>
<pre><code>>>> import re
>>> regex = re.compile(r'(?P<count>\d+)')
>>> match = regex.match('42')
>>> print match.groupdict()
{'count': '42'}
</code></pre>
<p>I know the <code>?P</code> indicates that it's a Python-specific regex feature, but I'm hoping it's in Perl in a different way or was added later on. Is there any way to get a result hash in a similar manner in Perl?</p>

288,988 | <p>I was trying to follow some instructions today, and it starts with the comment </p>
<pre><code>
REM In SQLPlus I manually copy in each line and execute it.
</code></pre>
<p>That's nice, I don't have SQLPlus, I have SQLDeveloper. The lines that were pasted in were of the type:</p>
<pre><code>
@\\server\dir\dir\dir\commandfile1.txt;
COMMIT;
</code></pre>
<p>...etc.</p>
<p>It didn't like it when I tried that in a SQL window. I opened up and pasted in the commands by hand, and it wasn't happy with that either. (Did I mention that I'm not so good with this application nor Oracle, but that everyone else was out today?) The files there started with code like:</p>
<pre><code>
rem
set echo on
rem
execute procedure_name ('parameter1', 'parameter2');
</code></pre>
<p>A co-worker did have SQLPlus, and together we got it resolved. But, is there a way for me to do this with SQLDeveloper, so I'm not stuck if he's out too?</p>

288,998 | <p>I was wondering if anyone can help me get started with creating a room in Sandy 3D. I know I can generate the planes, but I am unsure as to how to implement simple physics (i.e. the player cannot walk through a wall). Is there a simple way to do this, or should I look into something like WOW (3D physics engine for Flash)?</p>
<p>Thanks,
Cameron</p>

289,001 | <p>I have a MySQL table where an indexed <code>INT</code> column is going to be 0 for 90% of the rows. If I change those rows to use <code>NULL</code> instead of 0, will they be left out of the index, making the index about 90% smaller?</p>

289,002 | <p>I have a static class that I would like to raise an event as part of a try catch block within a static method of that class.</p>
<p>For example in this method I would like to raise a custom event in the catch. </p>
<pre><code>public static void saveMyMessage(String message)
{
try
{
//Do Database stuff
}
catch (Exception e)
{
//Raise custom event here
}
}
</code></pre>

289,003 | <p>I have an Asp.Net 1.1 application that uses the following code to write out an image file to a pop up web page.</p>
<pre><code> Response.ContentType="image/tiff" 'Only for Tif files

objStream = Server.CreateObject("ADODB.Stream")
objStream.open()
objStream.type = 1
objStream.loadfromfile(localfile)
Response.BinaryWrite(objStream.read)

<p>I'm testing this out with TIF files. The files are being displayed correctly in IE6 and Safari but in IE7 they are not displaying and nothing seems to be returning to the web page. Files with jpg, gif extensions are being displayed properly. What might be the problem here?</p>

289,010 | <p>Similar to <a href="https://stackoverflow.com/questions/188141/c-list-orderby-alphabetical-order">List<> OrderBy Alphabetical Order</a>, we want to sort by one element, then another. we want to achieve the functional equivalent of </p>
<pre><code>SELECT * from Table ORDER BY x, y
</code></pre>
<p>We have a class that contains a number of sorting functions, and we have no issues sorting by one element.<br>
For example: </p>
<pre><code>public class MyClass {
public int x;
public int y;
}
List<MyClass> MyList;
public void SortList() {
MyList.Sort( MySortingFunction );
}
</code></pre>
<p>And we have the following in the list: </p>
<pre><code>Unsorted Sorted(x) Desired
--------- --------- ---------
ID x y ID x y ID x y
[0] 0 1 [2] 0 2 [0] 0 1
[1] 1 1 [0] 0 1 [2] 0 2
[2] 0 2 [1] 1 1 [1] 1 1
[3] 1 2 [3] 1 2 [3] 1 2
</code></pre>
<p>Stable sort would be preferable, but not required. Solution that works for .Net 2.0 is welcome.</p>

289,029 | <p>It seems like the classical way to handle transactions with JDBC is to set auto-commit to false. This creates a new transaction, and each call to commit marks the beginning the next transactions.
On multithreading app, I understand that it is common practice to open a new connection for each thread.</p>
<p>I am writing a RMI based multi-client server application, so that basically my server is seamlessly spawning one thread for each new connection.
To handle transactions correctly should I go and create a new connection for each of those thread ?
Isn't the cost of such an architecture prohibitive?</p>

289,076 | <p>Example C API signature:</p>
<p><code>void Func(unsigned char* bytes);</code></p>

289,106 | <p><a href="https://stackoverflow.com/questions/286584/can-i-specify-interfaces-when-i-declare-a-member#287669">Can I specify interfaces when I declare a member?</a></p>
<p>After thinking about this question for a while, it occurred to me that a static-duck-typed language might actually work. Why can't predefined classes be bound to an interface at compile time? Example:</p>
<pre><code>public interface IMyInterface
{
public void MyMethod();
}
public class MyClass //Does not explicitly implement IMyInterface
{
public void MyMethod() //But contains a compatible method definition
{
Console.WriteLine("Hello, world!");
}
}
...
public void CallMyMethod(IMyInterface m)
{
m.MyMethod();
}
...
MyClass obj = new MyClass();
CallMyMethod(obj); // Automatically recognize that MyClass "fits"
// MyInterface, and force a type-cast.
</code></pre>
<p>Do you know of any languages that support such a feature? Would it be helpful in Java or C#? Is it fundamentally flawed in some way? I understand you could subclass MyClass and implement the interface or use the Adapter design pattern to accomplish the same thing, but those approaches just seem like unnecessary boilerplate code.</p>

289,108 | <p>I prefer to use jQuery with my ASP.NET MVC apps than the Microsoft Ajax library. I have been adding a parameter called "mode" to my actions, which I set in my ajax calls. If it is provided, I return a JsonViewResult. If it isn't supplied, I assume it was a standard Http post and I return a ViewResult.</p>
<p>I'd like to be able to use something similar to the IsMvcAjaxRequest in my controllers when using jQuery so I could eliminate the extra parameter in my Actions.</p>
<p>Is there anything out there that would provide this capability within my controllers or some simple way to accomplish it? I don't want to go crazy writing code since adding a single parameter works, it just isn't ideal.</p>

289,138 | <p>I was really looking at the differences between pass by value and how Java allocates objects and what java does to put objects on the stack.</p>
<p>Is there anyway to access objects allocated on the heap? What mechanisms does java enforce to guarantee that the right method can access the right data off the heap?</p>
<p>It seems like if you were crafty and maybe even manipulate the java bytecode during runtime, that you might be able to manipulate data off the heap when you aren't supposed to?</p>

289,176 | <p>I keep seeing the phrase "duck typing" bandied about, and even ran across a code example or two. I am way too <strike>lazy</strike> busy to do my own research, can someone tell me, briefly:</p>
<ul>
<li>the difference between a 'duck type' and an old-skool 'variant type', and </li>
<li>provide an example of where I might prefer duck typing over variant typing, and</li>
<li>provide an example of something that i would <em>have</em> to use duck typing to accomplish?</li>
</ul>
<p><img src="https://regmedia.co.uk/2007/05/03/cartoon_duck.jpg" alt="duck typing illustration courtesy of The Register"></p>
<p>I don't mean to seem fowl by doubting the power of this 'new' construct, and I'm not ducking the issue by refusing to do the research, but I am quacking up at all the flocking hype i've been seeing about it lately. It looks like <em>no</em> typing (aka dynamic typing) to me, so I'm not seeing the advantages right away.</p>
<p>ADDENDUM: Thanks for the examples so far. It seems to me that using something like 'O->can(Blah)' is equivalent to doing a reflection lookup (which is probably not cheap), and/or is about the same as saying (O is IBlah) which the compiler might be able to check for you, but the latter has the advantage of distinguishing my IBlah interface from your IBlah interface while the other two do not. Granted, having a lot of tiny interfaces floating around for every method would get messy, but then again so can checking for a lot of individual methods...</p>
<p>...so again i'm just not getting it. Is it a fantastic time-saver, or the same old thing in a brand new sack? Where is the example that <em>requires</em> duck typing?</p>

289,187 | <p>I have an Excel macro that deletes a sheet, copies another sheet and renames it to the same name of the deleted sheet. This works fine when run from Excel, but when I run it by calling the macro from Python I get the following error message:</p>
<blockquote>
<p>Run-time error '1004' - Cannot rename a sheet to the same name as
another sheet, a referenced object library or a workbook referenced by
VisualBasic.</p>
</blockquote>
<p>The macro has code like the following:</p>
<pre><code>Sheets("CC").Delete
ActiveWindow.View = xlPageBreakPreview
Sheets("FY").Copy After:=Sheets(Sheets.Count)
Sheets(Sheets.Count).Name = "CC"
</code></pre>
<p>and the debugger highlights the error on the last line where the sheet is renamed. I've also tried putting these calls directly in python but get the same error message.</p>
<p>Any suggestions are much appreciated!</p>
<p>Thanks.</p>

289,208 | <p>Since upgrading to 2008 I and many people here have noticed that randomly VS will no longer step in to code or jump over breakpoints. Its got to the stage where debugging is becoming a real chore. We are running SP1 but noticed problem on 2008 basic too.</p>
<p>In ref to Robert's question: We host WCF and Remoting services inside windows services. Essentially the calls from the clients (generally windows exe) will end up in a thread on the service itself and in our code (as opposed to remoting or WCF infrastructure). Once in our code the break points have this behaviour.</p>
<p>Much of the debugging we do here is in service code so ATTACH to process to invaluable and sometimes is impossible to get to the state needed except by attaching to processes after they have started. It happens to developers both with extensions such as resharper and to those who run a vanilla VS.</p>
<p>Looking on google doesn't give much help.</p>
<h2>Anyone else experience this?</h2>

289,220 | <p>Below is my (simplified) schema (in MySQL ver. 5.0.51b) and my strategy for updating it. There has got to be a better way. Inserting a new item requires 4 trips to the database and editing/updating an item takes up to <strong>7</strong>!</p>
<p><strong>items</strong>: itemId, itemName
<br /><strong>categories</strong>: catId, catName
<br /><strong>map</strong>: mapId*, itemId, catId
<br />* mapId (varchar) is concat of itemId + | + catId</p>
<p>1) If inserting: insert item. Get itemId via MySQL API.
<br />Else updating: just update the item table. We already have the itemId.</p>
<p>2) Conditionally batch insert into <code>categories</code>.</p>
<pre><code>INSERT IGNORE INTO categories (catName)
VALUES ('each'), ('category'), ('name');
</code></pre>
<p>3) Select IDs from <code>categories</code>.</p>
<pre><code>SELECT catId FROM categories
WHERE catName = 'each' OR catName = 'category' OR catName = 'name';
</code></pre>
<p>4) Conditionally batch insert into <code>map</code>.</p>
<pre><code>INSERT IGNORE INTO map (mapId, itemId, catId)
VALUES ('1|1', 1, 1), ('1|2', 1, 2), ('1|3', 1, 3);
</code></pre>
<p>If inserting: we're done. Else updating: continue.</p>
<p>5) It's possible that we no longer associate a category with this item that we did prior to the update. Delete old categories for this itemId.</p>
<pre><code>DELETE FROM MAP WHERE itemId = 2
AND catID <> 2 AND catID <> 3 AND catID <> 5;
</code></pre>
<p>6) If we have disassociated ourselves from a category, it's possible that we left it orphaned. We do not want categories with no items. Therefore, if <code>affected rows > 0</code>, kill orphaned categories. I haven't found a way to combine these in MySQL, so this is #6 & #7.</p>
<pre><code>SELECT categories.catId
FROM categories
LEFT JOIN map USING (catId)
GROUP BY categories.catId
HAVING COUNT(map.catId) < 1;
</code></pre>
<p>7) Delete IDs found in step 6.</p>
<pre><code>DELETE FROM categories
WHERE catId = 9
AND catId = 10;
</code></pre>
<p>Please tell me there's a better way that I'm not seeing.</p>

289,241 | <p>Forgive me for a potentially silly question here, but in other programming languages (scripting ones like PHP or Perl) it is often easy to dump everything contained within a variable.</p>
<p>For instance, in PHP there are the <code>var_dump()</code> or <code>print_r()</code> functions. Perl has the <code>Data::Dumper</code> CPAN class, etc etc.</p>
<p>Is there something like this for Objective-C? It would be very convenient in a few cases to be able to dump everything like that, instead of using gdb to inspect each variable.</p>

289,255 | <p>Title says it mostly. I want to add a simple extension method to the base Dictionary class in C#. At first I was going to name it Pop(TKey key), kind of like the Stack method, but it accepts a key to use for lookup.</p>
<p>Then I was going to do Take(TKey key), but it coincides with the LINQ method of the same name...and although C# 3.0 lets you do it, I don't like it.</p>
<p>So, what do you think, just stick with Pop or is there a better term for "find and remove an element"?</p>
<p>(I feel kind of embarrassed to ask this question, it seems like such a trivial matter... but I like to use standards and I don't have wide experience with many languages/environments.)</p>
<p>EDIT: Sorry, should have explained more.... In this instance I can't use the term Remove since it's already defined by the class that I'm extending with a new method.</p>
<p>EDIT 2: Okay, here's what I have so far, inspired by the wisdom of the crowd as it were:</p>
<pre><code>public static TValue Extract<TKey, TValue>
(
this Dictionary<TKey, TValue> dict,
TKey key
)
{
TValue value = dict[key];
dict.Remove(key);
return value;
}
public static bool TryExtract<TKey, TValue>
(
this Dictionary<TKey, TValue> dict,
TKey key,
out TValue value
)
{
if( !dict.TryGetValue(key, out value) )
{
return false;
}
dict.Remove(key);
return true;
}
</code></pre>

289,274 | <p>I have included <code><zlib.h></code> in my iphone application and the source code I was mocking up the sample code of Molecules provided by Brad Larson, however, when I build the project, it returns the error as below.

289,276 | <p>Here's my code (note that this was given by a friend):</p>
<pre><code>Private Sub Browse_Click()
Dim textfile As String
textfile = Space(255)
GetFileNameFromBrowseW Me.hWnd, StrPtr(sSave), 255, StrPtr("c:\"),
StrPtr("txt"), StrPtr("Apps (*.txt)" + Chr$(0) + "*.txt" + Chr$(0) +
"All files (*.*)" + Chr$(0) + "*.*" + Chr$(0)), StrPtr("Select File")
Text1 = Left$(textfile, lstrlen(textfile))
End Sub
</code></pre>
<p>Basically later on I edit the text file selected so later I call it just by using textfile in my function. However I get a path not found so I feel like I'm doing something wrong.
Thanks in advance.</p>
<p>Edit: All I want to do is select a text file, then later be able to call it and use it.</p>

289,307 | <p>Say I have two lists:</p>
<pre><code>var list1 = new int[] {1, 2, 3};
var list2 = new string[] {"a", "b", "c"};
</code></pre>
<p>Is it possible to write a LINQ statement that will generate the following list:</p>
<pre><code>var result = new []{
new {i = 1, s = "a"},
new {i = 1, s = "b"},
new {i = 1, s = "c"},
new {i = 2, s = "a"},
new {i = 2, s = "b"},
new {i = 2, s = "c"},
new {i = 3, s = "a"},
new {i = 3, s = "b"},
new {i = 3, s = "c"}
};
</code></pre>
<p>?</p>
<p>Edit: I forgot to mention I didn't want it in query syntax. Anyway, based on preetsangha's answer I've got the following:</p>
<pre><code>var result = list1.SelectMany(i => list2.Select(s => new {i = i, s = s}));

289,311 | <p>I want to output a timestamp with a PST offset (e.g., 2008-11-13T13:23:30-08:00). <code>java.util.SimpleDateFormat</code> does not seem to output timezone offsets in the <em>hour:minute</em> format, it excludes the colon. Is there a simple way to get that timestamp in Java?</p>
<pre><code>// I want 2008-11-13T12:23:30-08:00
String timestamp = new SimpleDateFormat("yyyy-MM-dd'T'h:m:ssZ").format(new Date());
System.out.println(timestamp);
// prints "2008-11-13T12:23:30-0800" See the difference?
</code></pre>
<p>Also, <code>SimpleDateFormat</code> cannot properly parse the example above. It throws a <code>ParseException</code>.</p>
<pre><code>// Throws a ParseException
new SimpleDateFormat("yyyy-MM-dd'T'h:m:ssZ").parse("2008-11-13T13:23:30-08:00")

<p>However, those results are practically meaningless- I have 100% coverage according to rcov (as it only covers C0 analysis) and I've barely written half the test cases for the functionality that exists thus far.</p>
<p>I'm used to the useful results from the code coverage in Visual Studio 2008 Team, which has C1 coverage. Are there any tools that provide similar coverage for ruby?</p>

289,324 | <p>I was remote debugging a stack overflow from a recursive function. The Visual Studio IDE only showed the first 1,000 frames (all the same function), but I needed to go up further too see what the cause was.</p>
<p>Does anybody know how to get VS to 'move up' in a stack listing?</p>
<p>Thanks. </p>

289,329 | <p>I was trying to create a pseudo super struct to print array of structs. My basic
structures are as follows.</p>
<pre><code>/* Type 10 Count */
typedef struct _T10CNT
{
int _cnt[20];
} T10CNT;
...
/* Type 20 Count */
typedef struct _T20CNT
{
long _cnt[20];
} T20CNT;
...
</code></pre>
<p>I created the below struct to print the array of above mentioned structures. I got dereferencing void pointer error while compiling the below code snippet.</p>
<pre><code>typedef struct _CMNCNT
{
long _cnt[3];
} CMNCNT;
static int printCommonStatistics(void *cmncntin, int cmncnt_nelem, int cmncnt_elmsize)
{
int ii;
for(ii=0; ii<cmncnt_nelem; ii++)
{
CMNCNT *cmncnt = (CMNCNT *)&cmncntin[ii*cmncnt_elmsize];
fprintf(stout,"STATISTICS_INP: %d\n",cmncnt->_cnt[0]);
fprintf(stout,"STATISTICS_OUT: %d\n",cmncnt->_cnt[1]);
fprintf(stout,"STATISTICS_ERR: %d\n",cmncnt->_cnt[2]);
}
return SUCCESS;
}
T10CNT struct_array[10];
...
printCommonStatistics(struct_array, NELEM(struct_array), sizeof(struct_array[0]);
...
</code></pre>
<p>My intention is to have a common function to print all the arrays. Please let me know the correct way of using it.</p>
<p>Appreciate the help in advance.</p>
<p>Edit: The parameter name is changed to cmncntin from cmncnt. Sorry it was typo error.</p>
<p>Thanks,
Mathew Liju</p>

289,347 | <p>I have a string that I would like to tokenize.
But the C <code>strtok()</code> function requires my string to be a <code>char*</code>.
How can I do this simply?</p>
<p>I tried:</p>
<pre><code>token = strtok(str.c_str(), " ");
</code></pre>
<p>which fails because it turns it into a <code>const char*</code>, not a <code>char*</code></p>

289,360 | <p>I have a large UIScrollView into which I'm placing 3-4 rather large (320x1500 pixels or so) UIImageView image tiles. I'm adding these UIImageViews to the scroll view inside of my NIB files. I have one outlet on my controller, and that is to the UIScrollView. I'm using a property (nonatomic, retain) for this, and sythesizing it.</p>
<p>My question is this: When I observe this in Memory Monitor, I can see that the memory used goes up quite a bit when the view with all these images is loaded (as expected). But when I leave the view, it and its controller are dealloc'd, but do not seem to give up anywhere near the memory they had taken up. When I cut one of these views (there are several in my app) down to just 1-3 images that were 320x460 and left everything else the same, it recaptures the memory just fine.</p>
<p>Is there some issue with using images this large? Am I doing something wrong in this code (pasted below)?</p>
<p>This is a snippet from the viewController that is causing problems.</p>
<pre><code>- (CGFloat)findHeight
{
UIImageView *imageView = nil;
NSArray *subviews = [self.scrollView subviews];
CGFloat maxYLoc = 0;
for (imageView in subviews)
{
if ([imageView isKindOfClass:[UIImageView class]])
{
CGRect frame = imageView.frame;
if ((frame.origin.y + frame.size.height) > maxYLoc) {
maxYLoc = frame.origin.y;
maxYLoc += frame.size.height;
}
}
}
return maxYLoc;
}
- (void)viewDidLoad {
[super viewDidLoad];
[self.scrollView setContentSize:CGSizeMake(320, [self findHeight])];
[self.scrollView setCanCancelContentTouches:NO];
self.scrollView.indicatorStyle = UIScrollViewIndicatorStyleWhite;
self.scrollView.clipsToBounds = YES;
self.scrollView.scrollEnabled = YES;
self.scrollView.pagingEnabled = NO;
}
- (void)dealloc {
NSLog(@"DAY Controller Dealloc'd");
self.scrollView = nil;
[super dealloc];
}
</code></pre>
<p>UPDATE: I've noticed another weird phenomenon. If I don't use the scroll on the view, it seems to be hanging on to the memory. But if I scroll around a bunch and ensure that all of the UIImageViews became visible at one point, it will free up and regain most of the memory it lost.</p>
<p>UPDATE2: The reason I'm asking this is my app is actually crashing due to low memory. I wouldn't mind if it were just caching and using up extra memory, but it doesn't seem to ever release it - even in didReceiveMmoryWarning conditions</p>

289,362 | <p>I'm using the MySQL Query Browser (part of the <a href="http://dev.mysql.com/downloads/gui-tools/" rel="noreferrer">MySQL GUI Tools</a>) and need to change a field to NULL, but I can't figure out how to do it - if I delete the value it tries to update it to <code>''</code>. Typing "NULL" makes it try to update to <code>'NULL'</code> (a string).</p>
<p>I know I could just write a query to do it, but that defeats the entire purpose of the tool, no?</p>

289,405 | <p>When I'm writing some tight loop that needs to work fast I am often bothered by thoughts about how the processor branch prediction is going to behave. For instance I try my best to avoid having an if statement in the most inner loop, especially one with a result which is not somewhat uniform (say evaluates to true or false randomly). </p>
<p>I tend to do that because of the somewhat common knowledge that the processor pre-fetches instructions and if it turned out that it mis-predicted a branch then the pre-fetch is useless.</p>
<p>My question is - Is this really an issue with modern processors? How good can branch prediction expected to be?<br>
What coding patterns can be used to make it better?</p>
<p>(For the sake of the discussion, assume that I am beyond the "early-optimization is the root of all evil" phase)</p>

289,409 | <p>I have a layout that is working, but it has one very annoying problem.. when the content is taller than the screen, the background stops.</p>
<p>This is the desired layout in bad-ASCII-art format:</p>
<pre><code>_____________________ _
| | long |logo| |
| | content | | |
| | | | |
| | | | |
|grad| |grad| | Viewport
| | | | |
| | | | |
| | | | _|
| | | |
| | | |
_____________________
|2em| <-20em->| 2em|
</code></pre>
<p>..or with short content..</p>
<pre><code>_____________________ _
| | short |logo| |
| | content | | |
| | | | |
| | | | |
|grad| |grad| | Viewport
| | | | |
| | | | |
| | | | |
| | | | |
_____________________ _|
</code></pre>
<p>Basically it looks like a single column, with a glow as a column either side. Over the left-glow is a logo. When the content is short, it is still the full-height.</p>
<p>I have tried using the <a href="http://www.dustindiaz.com/min-height-fast-hack/" rel="nofollow noreferrer">CSS min-height hack</a>, which fixes the middle column, but then the gradients only extend as far as the content (in the left column, a single <code>&nbsp;</code>, in the right column the logo)</p>
<hr>
<p>Here is what the layout looks like:</p>
<p><img src="https://i.stack.imgur.com/CVm4I.png" alt="Layout"></p>
<p>And the problem (when the browser window is shrunk vertically):</p>
<p><img src="https://i.stack.imgur.com/CVhOL.png" alt="Problem"></p>
<p>Finally, the problem HTML/CSS, <a href="http://data.dbrweb.co.uk/tmp/fifestock_layout_problem/" rel="nofollow noreferrer">http://data.dbrweb.co.uk/tmp/fifestock_layout_problem/</a></p>

289,432 | <p>Basically, I'm trying to write the following (pseudocode) in an ASP.NET HttpModule:</p>
<pre><code>*pre-code*
try { handler.ProcessRequest(...) }
catch (Exception) { *error-code* }
finally { *post-code* }
</code></pre>
<p>I've found that I can hook into HttpModule.PreExecuteHandler for "pre-code" and .Error for "error-code". But PostExecuteHandler doesn't seem to be running reliably.</p>
<p>BeginRequest and EndRequest run reliably but are too early for the code I need to write, which requires inspection of the handler that was chosen to execute. The handler isn't chosen until after BeginRequest.</p>
<p>Is there a best practice for writing this kind of wrapper?</p>
<p>Thanks!</p>
