  • How to add a cross-browser mouse wheel function to a div in javascript?

    - by Shaunwithanau
    I am trying to stop the default mouse wheel event that is called on the window and on a div and call my own function instead on the div. I need this to be cross-browser (without the use of a library. I know I need to use an eventListener and I think have to use both onmousewheel and DOMMouseScroll (for FF) but I think am getting caught up in the implementation somewhere. I appreciate any and all help.

  • QUiLoader and ignored dynamic properties

    - by Googie
    I'm loading the .ui file, where one of the widgets (QComboBox) has a dynamic property (http://qt-project.org/doc/qt-5/properties.html#dynamic-properties). The UI file looks like this: <?xml version="1.0" encoding="UTF-8"?> <ui version="4.0"> <class>PopulateScriptConfig</class> <widget class="QWidget" name="PopulateScriptConfig"> <property name="geometry"> <rect> <x>0</x> <y>0</y> <width>400</width> <height>300</height> </rect> </property> <property name="windowTitle"> <string>Form</string> </property> <layout class="QVBoxLayout" name="verticalLayout"> <item> <widget class="QGroupBox" name="langGroup"> <property name="title"> <string>Language</string> </property> <layout class="QVBoxLayout" name="verticalLayout_3"> <item> <widget class="QComboBox" name="langCombo"> <property name="ScriptingLangCombo" stdset="0"> <bool>true</bool> </property> </widget> </item> </layout> </widget> </item> <item> <widget class="QGroupBox" name="codeGroup"> <property name="title"> <string>Implementation</string> </property> <layout class="QVBoxLayout" name="verticalLayout_2"> <item> <widget class="QPlainTextEdit" name="codeEdit"/> </item> </layout> </widget> </item> </layout> </widget> <resources/> <connections/> </ui> The important part is: <widget class="QComboBox" name="langCombo"> <property name="ScriptingLangCombo" stdset="0"> <bool>true</bool> </property> </widget> I'm loading the file with QUiLoader::load(). Note, that I have extended the QUiLoader class, but only to access createWidget() method, where I can query each widget like this: QWidget* UiLoader::createWidget(const QString& className, QWidget* parent, const QString& name) { QWidget* w = QUiLoader::createWidget(className, parent, name); qDebug() << w->dynamicPropertyNames(); return w; } As a result I see empty list displayed, so it seems like the dynamic property is completly ignored. Any ideas? P.S. I've made sure that I load correct file. 3 times.

  • tomcat startup.sh trouble finding JAVA_HOME

    - by peter
    I am a bit puzzled by this strange behavior on CentOs 5.4 when starting Tomcat 6.0 as a service I've added a script at /etc/init.d/tomcat that can start/stop/restart Apache Tomcat 6.0 with user 'tomcat', and registered it as service. The problem with the service is that I am getting a 'Neither the JAVA_HOME nor the JRE_HOME environment variable is defined'. But when type 'sudo -u tomcat echo $JAVA_HOME' I get '/usr/java/jdk1.5.0_22' which is correct since I am using that JDK. What can I do about this?

  • .htaccess or PHP protection code against multiple speedy requests

    - by Phil Jackson
    Hi, I am looking for ideas for how I can stop external scripts connecting with my site. I'm looking for the same kind of idea behind Google. As in if a certain amount of requests are made per a certain amount of time then block the IP address or something. I thought there maybe a htaccess solution if not, I will write a PHP one. Any ideas or links to existing methods or scripts is much appreciated. Regards Phil

  • Default profile for large

    - by user63434
    Hi I am setting up a master image to clone to all same machine type Windows 7 client, I login as administrastor and installed all the programs and changed the desktop settings etc, but my local administrator profile is 244megs in size, which will become the default profile of the local machine when sysprep, we have a 2003 server that I want to use mandatory profile for all login users which means I need to copy this profile to the server so when any users login to the domain they are using this profile, loading a 244megs profile is going to be very slow since it will be removed from the client when they logoff. So next time they login it will take a long time again. Is there anything I can do, can I just copy just the bare minimum files from the default profile to the server, as I am not sure what parts I need, I read that I must copy my documents, my documents/pictures so the folder redirection will work. What else do I need to copy to the server? I have firefox xmark sync also and MS words etc. THanks

  • website lookup extremely slow in ubuntu

    - by ubuntulover
    Hi I have a wireless broadband connection through a router and wireless modem. Everything works fine in Windows. However, in ubuntu on the same machine, websites seem to take longer to start loading. I think the dns lookup is slow. I think https sites may be slower, as Ijust can't log in to gmail. I am also using a mercurial repo with remote origin, and it takes forever (like 5 minutes) to push one small change. I think it is because it has to communicate through https multiple times. Should I change my dns server? I've seen that I don't have these problems at my work network (they have another dns server). This happens with the IPv4 settings being automatic (dhcp). When I change it to automatic (dhcp) addresses only, and add google's 8.8.8.8 in the dns servers, it still takes forever. Why is this happening?

  • Visual Studio 2008 - Assemblies are not loaded into Modules after relocating the website and project

    - by user296861

  • EC2 Windows 2008 VM import Not Working

    - by remack
    I am trying to upload a Windows 2008 SP2 server image to Amazon EC2, but once the process is complete, I can't connect to it. I had ops export a VMDK from our datacenter. The image appeared to have a fixed IP, so I loaded it in VMWare player and enabled DHCP. I uploaded it following amazon's instructions: http://aws.amazon.com/ec2/vmimport/ I start the new instance and try to RDP to the public DNS; connection fails. My two thoughts are: Loading it in VMWare player messed it up somehow, since the instructions say use an ESX image. The image they made me had the wrong network adapter type. The image has an Intel(R) PRO/1000 MT adapter using the E1G60I32.sys driver.

  • Can I use IP addresses to limit API access

    - by ed209
    I have a mini API that is only for an app I have built. The API service is on a separate domain to my app. I make jsonp calls to it and receive json in return. Therefore I only want my app to be able to access it. Can I just list a series of IP addresses for my app and allow them? Is there a better way to stop requests from anyone else to my API?

  • .htaccess rules not working, but the file seems to be loaded

    - by user221877
    I am trying to remove .php at the end of the URL from any page thats loaded. RewriteEngine on RewriteCond %{REQUEST_FILENAME} !-d RewriteCond %{REQUEST_FILENAME}.php -f RewriteRule ^(.*)$ $1.php Its running on my own server, which has WHM/cPanel, so I can change settings at the server level, I'm just not really sure what I'm looking for. I found the httpd.conf file, but it said it was auto generated by whm, so I tried looking in whm for the correct settings but it had barely any settings related to htaccess. If I fill htaccess with gibberish it stops the site from loading, which I assume means that the .htaccess file is being loaded, so I'm not sure what the issue is.

  • Find out when all processes in (void) is done?

    - by Emil
    Hey. I need to know how you can find out when all processes (loaded) from a - (void) are done, if it's possible. Why? I'm loading in data for a UITableView, and I need to know when a Loading... view can be replaced with the UITableView, and when I can start creating the cells. This is my code: - (void) reloadData { NSAutoreleasePool *releasePool = [[NSAutoreleasePool alloc] init]; NSLog(@"Reloading data."); NSURL *urlPosts = [NSURL URLWithString:[NSString stringWithFormat:@"%@", URL]]; NSError *lookupError = nil; NSString *data = [[NSString alloc] initWithContentsOfURL:urlPosts encoding:NSUTF8StringEncoding error:&lookupError]; postsData = [data componentsSeparatedByString:@"~"]; [data release], data = nil; urlPosts = nil; self.numberOfPosts = [[postsData objectAtIndex:0] intValue]; self.postsArrayID = [[postsData objectAtIndex:1] componentsSeparatedByString:@"#"]; self.postsArrayDate = [[postsData objectAtIndex:2] componentsSeparatedByString:@"#"]; self.postsArrayTitle = [[postsData objectAtIndex:3] componentsSeparatedByString:@"#"]; self.postsArrayComments = [[postsData objectAtIndex:4] componentsSeparatedByString:@"#"]; self.postsArrayImgSrc = [[postsData objectAtIndex:5] componentsSeparatedByString:@"#"]; NSMutableArray *writeToPlist = [NSMutableArray array]; NSMutableArray *writeToNoImagePlist = [NSMutableArray array]; NSMutableArray *imagesStored = [NSMutableArray arrayWithContentsOfFile:[rootPath stringByAppendingPathComponent:@"imagesStored.plist"]]; int loop = 0; for (NSString *postID in postsArrayID) { if ([imagesStored containsObject:[NSString stringWithFormat:@"%@.png", postID]]){ NSLog(@"Allready stored, jump to next.

If image is empty, try one more time or use noImage.png, set in IB if (imageData == nil){ NSLog(@"imageData is empty before trying .jpeg"); // If image == nil, try to replace .jpg with .jpeg, and if that worked, set cellImage to that image.

What is happening here? And how do I stop it?
