  • WPF - attached behavior to capture MouseEnter on Image in TreeviewITem

    - by pileggi
    Hi! Could I have, please, a little code-sample of WPF "attached behavior"? I explain my problem: I've done my TreeView all with XAML but now I'd like to manage an event with code-behind. The HierarchicalDataTemplate contains an Image. I need to capture the events MouseEnter / MouseLeave on the Image. I'd like to do this with "attached behavior", but I don't know how. Thank you!

  • PySide Qt4 widget exchange in a hboxlayout

    - by viraptor
    I'd like to exchange a widget inside a QHBoxLayout. This code seems to work, but as soon as I do the actual app._exec(), the code crashes with terminate called after throwing an instance of 'boost::python::error_already_set'. Is there any way to get the actual error message? (or to resolve this problem) gaParent = gameArea.parent().layout() gaParent.removeWidget(gameArea) gameArea = DrawingScreen() gameArea.setObjectName("gameArea") gaParent.insertWidget(0, gameArea)

  • Does a wrapper class for a COM interop IStream already exist?

    - by AnthonyWJones
    I'm about to write a Wrapper for a COM interop IStream so that code that expects a standard .NET Stream can use it. However it occurs to me that this sort of thing may already have been done before (although I haven't been able to find it myself with web searching). So I'm just putting this out here in case I'm about to re-invent the wheel. Note I've come across code implementing IStream wrapping a .NET stream but I need the reverse.

  • Corliss Expert Group Home Security: How to Secure Your Home without Spending Too Much?

    - by Mika Esmond
    HOME SECURITY: HOW TO SECURE YOUR HOME WITHOUT SPENDING TOO MUCH Imagine if there were no burglar or criminals who threaten the safety of our homes; we will be surprised how much savings we would have on several things we do to secure ourselves and our loved ones. We would not need fences, gates with locks, doors locks, window grills, CCTV cams, perimeter lighting, shotguns and baseball bats. The cost of maintaining these things can run up to the entire cost of building another room or, in some cases, a whole new house. The rationale for home security is the same for national security. A nation maintains an army whether it has enemies or not; so, whether burglars will come or not, we have to prepare for the eventuality. Hence, we end up spending for something we might never put into the actual use it was intended for. You buy a pistol and when a burglar breaks in you fire the gun either to scare or disable the intruder. We hope we will never have to use these things; but we still buy them for the peace of mind that comes from knowing we can secure or protect our family and home.

  • How to Pass a JS Variable to a PHP Variable

    - by dmullins
    Hello: I am working on a web application that currently provides a list of documents in a MySql database. Each document in the list has an onclick event that is suppose to open the specific document, however I am unable to do this. My list gets popluated using Ajax. Here is the code excerpt (JS): function stateChanged() { if (xmlhttp.readyState==4) { //All documents// document.getElementById("screenRef").innerHTML="<font id='maintxt'; name='title'; onclick='fileopen()'; color='#666666';>" + xmlhttp.responseText + "</font>"; } } } The onclick=fileopen event above triggers the next code excerpt, which downloads the file (JS): function stateChanged() { if (xmlhttp.readyState==4) { //Open file var elemIF = document.createElement("iframe"); elemIF.src = url; elemIF.style.display = "none"; document.body.appendChild(elemIF); } } } Lastly, the openfile onclick event triggers the following php code to find the file for downloading (php): $con = mysql_connect("localhost", "root", "password"); if (!$con) { die('Could not connect: ' . mysql_error()); } mysql_select_db("Documents", $con); $query = mysql_query("SELECT name, type, size, content FROM upload WHERE name = NEED JS VARIABLE HERE"); $row = mysql_fetch_array($query); header ("Content-type: ". $row['type']); header ("Content-length: ". $row['size']); header ("Content-Disposition: attachement; filename=". $row['name']); echo $row['content']; This code works well, for downloading a file. If I omit the WHERE portion of the Sql query, the onclick event will download the first file. Somehow, I need to get the screenRef element text and change it into a variable that my php file can read. Does anyone know how to do this? Also, without any page refreshes. I really appreciate everyone's feedback and thank you in advance. DFM

  • JBossMQ - Clustered Queues/NameNotFoundException: QueueConnectionFactory error

    - by mfarver
    I am trying to get an application working on a JBoss Cluster. It uses Queues internally, and the developer claims that it should work correctly in a clustered environment. I have jbossmq setup as a ha-singleton on the cluster. The application works correctly on whichever node currently is running the queue, but fails on the other nodes with a: "javax.naming.NameNotFoundException: QueueConnectionFactory not bound" error. I can look at JNDIview from the jmx-console and see that indeed the QueueConnectionFactory class only appears on the primary node in the Global context. Is there a way to see the Cluster's JNDI listing instead of each server? The steps I took from a default Jboss 4.2.3.GA installation were to use the "all" configuration. Then removed /server/all/deploy/hsqldb-ds.xml and /deploy-hasingleton/jms/hsqldb-jdbc2-service.xml, copying the example/jms/mysq-jdbc2-service.xml file into its place (editing that file to use DefaultDS instead of MySqlDS). Finally I created a mysql-ds.xml file in the deploy directory pointing "DefaultDS" at an empty database. I created a -services.xml file in the deploy directory with the queue definition. like the one below: <server> <mbean code="org.jboss.mq.server.jmx.Queue" name="jboss.mq.destination:service=Queue,name=myfirstqueue"> <depends optional-attribute-name="DestinationManager"> jboss.mq:service=DestinationManager </depends> </mbean> </server> All of the other cluster features of working, the servers list each other in the view, and sessions are replicating back and forth. The JBoss documentation is somewhat light in this area, is there another setting I might have missed? Or is this likely to be a code issue (is there different code to do a JNDI lookup in a clusted environment?) Thanks

  • How do I rewrite a plist if its data types are immutable?

    - by dugla
    I am getting comfortable with using plists for initializing my app. I now want to save app state back to the plist used to initialize the app and I find myself stuck. At application startup I ingest the plist into an NSDictionary which is immutable. I now want to update the NSDictionary by replacing old values with new values for existing keys and write to the plist via [NSDictionary writeToFile:atomically]. How do I get around the immutability of NSDictionary? Thanks, Doug

  • Is there a limit on number of OLE objects that can be embedded in an excel sheet?

    - by Varun Mahajan
    I am adding OLE objects to an excel sheet through .net interop. However, after some calls, excel is not allowing adding more objects through code. Is there a limit? or am I doing something wrong. Dim Htmlshape As Microsoft.Office.Interop.Excel.Shape Htmlshape = xlWorkSheet.Shapes.AddOLEObject(, tmpFile, , True, strExplorerPath, 1, "") Running this code gives an error after say 1000 calls. So, am I crossing some limit here?

  • Why do static Create methods exist?

    - by GeReV
    I was wondering, why do static Create methods exist? For instance, why use this code: System.Xml.XmlReader reader = System.Xml.XmlReader.Create(inputUri); over this code: System.Xml.XmlReader reader = new System.Xml.XmlReader(inputUri); I cannot find the rationale for using one over the other, and can't find any relation between classes who use this construct over the other. Can anyone shed some light on this?

  • Is Java assert broken?

    - by BlairHippo
    While poking around the questions, I recently discovered the assert keyword in Java. At first, I was excited. Something useful I didn't already know! A more efficient way for me to check the validity of input parameters! Yay learning! But then I took a closer look, and my enthusiasm was not so much "tempered" as "snuffed-out completely" by one simple fact: you can turn assertions off.* This sounds like a nightmare. If I'm asserting that I don't want the code to keep going if the input listOfStuff is null, why on earth would I want that assertion ignored? It sounds like if I'm debugging a piece of production code and suspect that listOfStuff may have been erroneously passed a null but don't see any logfile evidence of that assertion being triggered, I can't trust that listOfStuff actually got sent a valid value; I also have to account for the possibility that assertions may have been turned off entirely. And this assumes that I'm the one debugging the code. Somebody unfamiliar with assertions might see that and assume (quite reasonably) that if the assertion message doesn't appear in the log, listOfStuff couldn't be the problem. If your first encounter with assert was in the wild, would it even occur to you that it could be turned-off entirely? It's not like there's a command-line option that lets you disable try/catch blocks, after all. All of which brings me to my question (and this is a question, not an excuse for a rant! I promise!): What am I missing? Is there some nuance that renders Java's implementation of assert far more useful than I'm giving it credit for? Is the ability to enable/disable it from the command line actually incredibly valuable in some contexts? Am I misconceptualizing it somehow when I envision using it in production code in lieu of statements like if (listOfStuff == null) barf();? I just feel like there's something important here that I'm not getting. *Okay, technically speaking, they're actually off by default; you have to go out of your way to turn them on. But still, you can knock them out entirely.

  • Need to optimize this PHP script for "recent posts". Fatal error when post count is high...

    - by Scott B
    The code below is resulting in an error on a site in which there are ~ 1500 posts. It performs fine when post count is nominal, however, this heavy load is exposing the weakness of the code and I'd like to optimize it. Interestingly, when I disable this menu and instead use the "Recent Posts" widget, the posts are drawn fine. So I'd probably do good to borrow from that code if I knew where to find it, or better yet, If I could call the widget directly in my theme, passing it a post count variable. Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 16384 bytes) in /home1/est/public_html/mysite/wp-includes/post.php on line 3462 The code is below. Its purpose is to list "recent posts". global $post; $cat=get_cat_ID('myMenu'); $cathidePost=get_cat_ID('hidePost'); $myrecentposts = get_posts(array('post_not_in' => get_option('sticky_posts'), 'cat' => "-$cat,-$cathidePost",'showposts' => $count-of-posts)); $myrecentposts2 = get_posts(array('post_not_in' => get_option('sticky_posts'), 'cat' => "-$cat,-$cathidePost",'showposts' => -1)); $myrecentpostscount = count($myrecentposts2); if ($myrecentpostscount > 0) { ?> <div class="recentPosts"><h4><?php if ($myHeading !=="") { echo $myHeading; } else { echo "Recent Posts";} ?></h4><ul> <?php $current_page_recent = get_post( $current_page ); foreach($myrecentposts as $idxrecent=>$post) { if($post->ID == $current_page_recent->ID) { $home_menu_recent = ' class="current_page_item'; } else { $home_menu_recent = ' class="page_item'; } $myclassrecent = ($idxrecent == count($myrecentposts) - 1 ? $home_menu_recent.' last"' : $home_menu_recent.'"'); ?> <li<?php echo $myclassrecent ?>><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></li> <?php } ; if (($myrecentpostscount > $count-of-posts) && $count-of-posts > -1){ ?><li><a href="<?php bloginfo('url'); ?>/recent">View All Posts</a></li><?php } ?></ul></div>

  • Visual Studio soft-crashing when encountering XAML Errors in initialize.

    - by Aren
    I've been having some serious issues with Visual Studio 2010 as of late. It's been crashing in a peculiar way when I encounter certain types of XAML errors during the InitializeComponent() of a control/window. The program breaks and visual studio gears up like it's catching an exception (because it is) and then stops midway displaying a broken highlight in my XAML file with no details as to what is wrong. Example: There is not pop outs, or details Anywhere about what is wrong, only a callstack that points to my InitializeComponent() call. Now normally I'd just do some trial and error to fix this problem, and find out where i messed up, but the real problem isn't my code. Visual Studio is rendered completely useless at this point. It reports my application still in "Running" mode. The Stop/Break/Restart buttons on the toolbar or in the menus don't do anything (but grey out). Closing the application does not stop this behaviour, closing visual studio gets it stuck in a massive loop where it yells at me complaining every file open is not in the debug project, then repeats this process when i have exausted every open file. I have to force-close devenv.exe, and after this happening 3-4 times in a row it's a lot of wasted time (as my projects are usually pretty big and studio can be quite slow @ loading). To the point Has anyone else experienced this? How can I stop studio from locking up. Can I at LEAST get information out of this beast another way so i can fix my XAML error sooner rather than after 3-4 trial-and-error compiles yielding the same crash? Any & All help would be appreciated. Visual Studio 2010 version: 10.0.30319.1RTM Edit & Update FWIW, mostly the errors that cause this are XamlParseExceptions (I figured this out after i found what was wrong with my XAML). I think I need to be clearer though, Im not looking for the solution to my code problem, as these are usually typos / small things, I'm looking for a solution to VStudio getting all buggered up as a result. The particular error in the above image that 100% for sure caused this was a XamlParseException caused by forgetting a Value attribute on a data trigger. I've fixed that part but it still doesn't tell my why my studio becomes a lump of neutered program when a perfectly normal exception is thrown in the parsing of the XAML. Code that will cause this issue (at least for me) This is the base template WPF Application, with the following Window.xaml code. The problem is a missing Value="True" on the <DataTrigger ...> in the template. It generates a XamlParseException and Visual Studio Crashes as described above when debugging it. Final Notes The following solutions did not help me: Restarting Visual Studio Rebooting Reinstalling Visual Studio

  • Downloading file with Python results in only 4.1kB

    I'm using simple code: import urllib2 response = urllib2.urlopen("http://www.mysite.com/getfile/4355") output = open('myfile.zip','wb') output.write(response.read()) output.close() The web-server is IIS + ASP.NET MVC 4 It returns FileResult wrapping a zip-file with "application/octet-stream" content-type. The problem is that downloaded zip file is broken - only 4.1kB size, where it must be 24kB. When I type the url adress in web-browser directly - it downloads and opens fine. Could you please, suggest, what's wrong with my Python code?

  • SSE SIMD Optimization For Loop
