  • Could you share your emacs dot-files for web development

    - by Gok Demir
    Hi, could you kindly share your emacs dot-files for web development that works with CSS, HTML, JavaScript, PHP and if possible with Python Django. I really need complete setup. I looked nXhtml and its good on some parts (html code completion works but sucks on indentation and CSS code completion does not work and says tag table is empty most cases. I really need something that works: code completion works out of the box, git integration and pretty indentation and supports multi-mode for mixed HTML, CSS, JavaScript, PHP code.

  • Jenkins swarm-plugin jar file, won't run in background

    - by JeanMertz
    We're working on an automation script for our Jenkins slaves on a local Unix server. To connect the slaves to the Jenkins master, we use the swarm plugin. Setting up the master was easy, and connecting clients is also easy with a single command. However, I am trying to get the slave command (a java application) to run in the background without stalling the current process, this doesn't seem to work. I've created an init.d file and added it to update-rc.d but that doesn't work. #!/bin/bash /usr/bin/java -jar /root/swarm-client-1.7-jar-with-dependencies.jar -executors 4 I've also tried to run it with an ampersand & to start the process in the background, but that doesn't work either because - from looking at the source - the jar file actually boots another process that is then started in the foreground. Any ideas on how to make this jar file start without stopping the bootstrap script?

  • Setting Background of a Jbutton

    - by mithun1538
    Hello there, I have 5 JButtons: b1, b2, b3, b4, b5. By default, their color is gray. When I click on any button, the background of that button changes to white. When I click another button, I want that previous clicked button to change its background to gray, and this newly clicked button to change its background to white. Here is the code that I wrote: int liveButton = 0; //holds the value of the button that is last clicked. //0 indicates no button clicked (in the beginning) private void ChangeInUsersList(int clickedButton) { switch(liveButton) { case 1 : b1.setBackground(Color.GRAY); break; case 2 : b2.setBackground(Color.GRAY); break; case 3 : b3.setBackground(Color.GRAY); break; case 4 : b4.setBackground(Color.GRAY); break; case 5 : b5.setBackground(Color.GRAY); break; default: System.out.println("No button to change"); } liveButton = clickedButton;// store the clicked button to change its //background later } private void b1ActionPerformed(java.awt.event.ActionEvent evt) { ChangeInUsersList(1); b1.setBackground(new java.awt.Color(255,255,255)); } private void b2ActionPerformed(java.awt.event.ActionEvent evt) { ChangeInUsersList(2); b2.setBackground(new java.awt.Color(255,255,255)); } private void b3ActionPerformed(java.awt.event.ActionEvent evt) { ChangeInUsersList(3); b3.setBackground(new java.awt.Color(255,255,255)); } private void b4ActionPerformed(java.awt.event.ActionEvent evt) { ChangeInUsersList(4); b4.setBackground(new java.awt.Color(255,255,255)); } private void b5ButtonActionPerformed(java.awt.event.ActionEvent evt) { ChangeInUsersList(5); b5.setBackground(new java.awt.Color(255,255,255)); } However, its not working as expected. When i click on a button, its background does change to white. However, if i click on some other button after that, the former button's background doesnt change to grey. I tried replacing Color.GREY with new java.awt.Color(236,233,216) - the rgb for grey but it still doesnt work.

  • How do you make a CSS-defined table-cell scroll?

    - by Giffyguy
    I want to be able to set the height of the table, and force the cells to scroll individually if they are larger than the table. Consider the following code: (see it in action here) <div style="display: table; position: absolute; width: 25%; height: 80%; min-height: 80%; max-height: 80%; left: 0%; top: 10%; right: 75%; bottom: 10%; border: solid 1px black;"> <div style="display: table-row;"> <div style="display: table-cell; border: solid 1px blue;"> {Some dynamic text content}<br/> This cell should shrink to fit it's contents. </div> </div> <div style="display: table-row;"> <div style="display: table-cell; border: solid 1px red; overflow: scroll;"> This should only take up the remainder of the table's vertical space. This should only take up the remainder of the table's vertical space. This should only take up the remainder of the table's vertical space. This should only take up the remainder of the table's vertical space. This should only take up the remainder of the table's vertical space. This should only take up the remainder of the table's vertical space. This should only take up the remainder of the table's vertical space. This should only take up the remainder of the table's vertical space. </div> </div> </div> If you open this code (in IE8, in my case) you'll notice that the second cell fits in the table nicely when the browser is maximized. In theory, when you shrink the browser (forcing the table to shrink as well), a vertical scrollbar should appear INSIDE the second cell when the table becomes too small to fit all of the content. But in reality, the table just grows vertically, beyond the bounds set by the CSS height attribute(s). Hopefully I've explained this scenario adequately... Does anyone know how I can get this to work?

  • Adding image to RichTextBox programatically does not show in Xaml property

    - by rotary_engine
    Trying to add an image to a RichTextBox progamatically from a Stream. The image displays in the text box, however when reading the Xaml property there is no markup for the image. private void richTextBox3_Drop(object sender, DragEventArgs e) { if (e.Data.GetDataPresent(DataFormats.FileDrop)) { FileInfo[] files = (FileInfo[])e.Data.GetData(DataFormats.FileDrop); using (Stream s = files[0].OpenRead()) { InlineUIContainer container = new InlineUIContainer(); BitmapImage bmp = new BitmapImage(); bmp.SetSource(s); Image img = new Image(); img.SetValue(Image.SourceProperty, bmp); container.Child = img; richTextBox3.Selection.Insert(container); } } } private void Button_Click_1(object sender, RoutedEventArgs e) { // this doesn't have the markup from the inserted image System.Windows.MessageBox.Show(richTextBox3.Xaml); } What is the correct way to insert an image into the RichTextBox at runtime so that it can be persisted to a data store? In the Xaml property.

  • Change UIButton Background Image more than once per second

    - by beta.services
    I am currently working with the iPhone SDK. I have a NSTimer that changes the background image of a UIButton. Once this is complete, it will trigger the same action again (reset the NSTimer) for a predetermined number of times. My problem is that if my NSTimer is set to execute more than once per second. (0.75, say) The background image wont change. I am using NSLog to check that the event fires. But the button image will just remain in its original state. Is there any way to change the background image more often than once per second? This is my timer : [NSTimer scheduledTimerWithTimeInterval: tmpLvlSpeed target: self selector: @selector(simPressRed:) userInfo: nil repeats: NO]; And the code to change the image: [btnRed setImage:[UIImage imageNamed:@"btn_red.png"] forState:UIControlStateNormal]; if tmpLvlSpeed is less than 1.0, the button image will never change. Even though the simPressRed function will still fire. Any clues? Is there an update cycle I can modify?

  • jquery ui-tabs widget , changing the color of the background with css causes problem with display

    - by Ronedog
    I'm using the jquery tabs plugin and want to have the background a light grey color. In the css section for tabs, I found this line of code where I manually added the background-color part: .ui-tabs .ui-tabs-panel { padding: 1em 1em; display: block; border-width: 0; background-color:#EEEEEE;} The problem comes as seen in the picture below, where the grey background is only extending down part of the way. I initially thought I could update the div container with the same background color, but it didn't work. It looks like that white portion below might be some kind of padding, so I looked for that in the css but everything I tried had the same effect. Anyone got some ideas? This is what the HTML looks like (Theoretically): <div id="tabs_here"> <ul> <li><a href="#" onclick="$('#T_1').html('Display the data');" >Item Groups</a> </li> </ul> <div id="T_1"></div> </div>

  • AVFoundation buffer comparison to a saved image

    - by user577552
    Hi, I am a long time reader, first time poster on StackOverflow, and must say it has been a great source of knowledge for me. I am trying to get to know the AVFoundation framework. What I want to do is save what the camera sees and then detect when something changes. Here is the part where I save the image to a UIImage : if (shouldSetBackgroundImage) { CGColorSpaceRef colorSpace = CGColorSpaceCreateDeviceRGB(); // Create a bitmap graphics context with the sample buffer data CGContextRef context = CGBitmapContextCreate(rowBase, bufferWidth, bufferHeight, 8, bytesPerRow, colorSpace, kCGBitmapByteOrder32Little | kCGImageAlphaPremultipliedFirst); // Create a Quartz image from the pixel data in the bitmap graphics context CGImageRef quartzImage = CGBitmapContextCreateImage(context); // Free up the context and color space CGContextRelease(context); CGColorSpaceRelease(colorSpace); // Create an image object from the Quartz image UIImage * image = [UIImage imageWithCGImage:quartzImage]; [self setBackgroundImage:image]; NSLog(@"reference image actually set"); // Release the Quartz image CGImageRelease(quartzImage); //Signal that the image has been saved shouldSetBackgroundImage = NO; } and here is the part where I check if there is any change in the image seen by the camera : else { CGImageRef cgImage = [backgroundImage CGImage]; CGDataProviderRef provider = CGImageGetDataProvider(cgImage); CFDataRef bitmapData = CGDataProviderCopyData(provider); char* data = CFDataGetBytePtr(bitmapData); if (data != NULL) { int64_t numDiffer = 0, pixelCount = 0; NSMutableArray * pointsMutable = [NSMutableArray array]; for( int row = 0; row < bufferHeight; row += 8 ) { for( int column = 0; column < bufferWidth; column += 8 ) { //we get one pixel from each source (buffer and saved image) unsigned char *pixel = rowBase + (row * bytesPerRow) + (column * BYTES_PER_PIXEL); unsigned char *referencePixel = data + (row * bytesPerRow) + (column * BYTES_PER_PIXEL); pixelCount++; if ( !match(pixel, referencePixel, matchThreshold) ) { numDiffer++; [pointsMutable addObject:[NSValue valueWithCGPoint:CGPointMake(SCREEN_WIDTH - (column/ (float) bufferHeight)* SCREEN_WIDTH - 4.0, (row/ (float) bufferWidth)* SCREEN_HEIGHT- 4.0)]]; } } } numberOfPixelsThatDiffer = numDiffer; points = [pointsMutable copy]; } For some reason, this doesn't work, meaning that the iPhone detects almost everything as being different from the saved image, even though I set a very low threshold for detection in the match function... Do you have any idea of what I am doing wrong?

  • Change Win7 desktop background via Win2k3 Group Policy

  • display wait gif until image is fully loaded

    - by Dimitris Baltas
    Most popular browsers, while rendering an image, they display it line-by-line top-to-bottom as it loads. I have a requirement that a wait gif should be displayed while the image is loading. When the image is fully loaded then it should be displayed instead of the wait gif. If it helps, the site is http://farros.gr, main image: /images/bg.jpg and the div containing the image is named #main-content-image.

  • Best way to pass image to server?

    - by Chris
    I have an SL3 application that needs to be able to pass an image to the server, and then the server will generate a PDF file with the image in it, and display it to the user. What I already have in place are the following: (1) Code to convert image to byte array (2) Code to generate PDF file with image The main problem that I am running into is the following: In order to bypass the pop-up blocker, which is a requirement for my application, I am using the following code: var button = new NavigationButton(); button.NavigateUri = new Uri("http://localhost:3616/PrintReport.aspx?ReportIndex=11&ActionType=Get&ReportIdentifier=" + reportIdentifier.ToString() + ""); button.TargetName = "_blank"; button.PerformClick(); Initially, I would pass the image to a WCF web service (as a byte array), and then "navigate" to the ASP.NET page that would display the report. However, if I do this, then I can not use my custom HyperlinkButton class, and, certain browsers, including Safari, will block a new window from opening up. Therefore, it appears that the only option is to use the HyperlinkButton class. What I need to be able to do is to somehow pass the image, as a byte array or some other data type, to the server, such that it can temporarily store the image, even if it is in a server variable, and then immediately retrieve it when I navigate to the PrintReport.aspx page. If I upload the image to an ASP.NET form and then use the HyperlinkButton class to navigate to the PrintReport page, it doesn't work, as the app navigates to the PrintReport page before the system has finished uploading the image. I can't pass it to a web service, as that would require that I navigate to the PrintReport.aspx page in the callback code of the web method that I would be passing the image to, and the HyperlinkButton will not allow that, based on security rules. Any help or ideas would be appreciated. Thanks. Chris

  • Why is button background defaulting to grey when IsPressed is true

    - by Dave Colwell
    Hey all, I have a simple problem. Using the IsPressed trigger i want to be able to set the background color of a button to something other than the default grey. Here is what the button looks like when it is not pressed and here is what it looks like when it is clicked Here is the trigger for the button. I know the trigger is firing correctly because of the glow effect around the edge of the button when it is clicked. I also know that the brush is correct because i tried it out as a background brush to see what it looked like. <Style.Triggers> <Trigger Property="IsMouseOver" Value="True"> <Setter Property="Background" Value="{DynamicResource ButtonHoverBrush}"/> <Setter Property="BitmapEffect" Value="{DynamicResource ButtonHoverGlow}"/> </Trigger> <!-- This is the trigger which is working but the background color wont change --> <Trigger Property="IsPressed" Value="True"> <Setter Property="BitmapEffect" Value="{DynamicResource ButtonHoverGlow}"/> <Setter Property="Background" Value="{DynamicResource ButtonPressedBrush}" /> </Trigger> </Style.Triggers>

  • UITableViewCell color issues with custom table view background

    - by Macatomy
    I have a UITableView with a custom background image set like this: self.tableView.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"mybg.png"]]; The background appears fine, but my UITableViewCells (default cells, not custom) have some sort of weird tint to them, and the UILabel containing the "New Project" text also seems to have some sort of background behind it. How can I remove this? I've already tried: cell.backgroundColor = [UIColor clearColor]; cell.textLabel.backgroundColor = [UIColor clearColor]; Thanks

  • Background worker not working right

    - by vbNewbie
    I have created a background worker to go and run a pretty long task that includes creating more threads which will read from a file of urls and crawl each. I tried following it through debugging and found that the background process ends prematurely for no apparent reason. Is there something wrong in the logic of my code that is causing this. I will try and paste as much as possible to make sense. While Not myreader.EndOfData Try currentRow = myreader.ReadFields() Dim currentField As String For Each currentField In currentRow itemCount = itemCount + 1 searchItem = currentField generateSearchFromFile(currentField) processQuerySearch() Next Catch ex As Microsoft.VisualBasic.FileIO.MalformedLineException Console.WriteLine(ex.Message.ToString) End Try End While This first bit of code is the loop to input from file and this is what the background worker does. The next bit of code is where the background worker creates threads to work all the 'landingPages'. After about 10 threads are created the background worker exits this sub and skips the file input loop and exits the program. Try For Each landingPage As String In landingPages pgbar.Timer1.Stop() If VisitedPages.Contains(landingPage) Then Continue For Else Dim thread = New Thread(AddressOf processQuery) count = count + 1 thread.Name = "Worm" & count thread.Start(landingPage) If numThread >= 10 Then For Each thread In ThreadList thread.Join() Next numThread = 0 Continue For Else numThread = numThread + 1 SyncLock ThreadList ThreadList.Add(thread) End SyncLock End If End If Next

  • How to get Firefox Greasemonkey script to use a local cascading stylesheet?

    - by Umber Ferrule
    What's the correct syntax to link to a CSS file in the same directory as a Greasemonkey JavaScript? I've tried the following but it doesn't work: var cssNode = document.createElement('link'); cssNode.type = 'text/css'; cssNode.rel = 'stylesheet'; cssNode.href = 'example.css'; cssNode.media = 'screen'; cssNode.title = 'dynamicLoadedSheet'; document.getElementsByTagName("head")[0].appendChild(cssNode); If I can get this to work, it would be a lot easier than encasing CSS changes in JavaScript.

    What i would like to do is to read an css file from a GET request on the client side, and then i would like to parse it to check all the classes. The problem is that I need to implement CSSOMParser for that, and here are the imports import org.w3c.dom.css.CSSRule; import org.w3c.dom.css.CSSRuleList; import org.w3c.dom.css.CSSStyleRule; import org.w3c.dom.css.CSSStyleSheet; import com.steadystate.css.parser.CSSOMParser; the problem is that none of those classes ale probably javascript compilant, so they don't want to compile if they're on the client side. Is there a way to get it done ?

  • Audio recording background noise

    - by Sergey
    For a long time time I've been trying to get rid of the background noise that appears in every audio recording I make with my computer. Tried different microphones, different sound setting, drivers. Interesting fact - the volume of this sound is equal whether I use and internal notebook microphone or an external one. I tried really good mics, so I'm sure the problem is not in it. Laptop on which this problem appears in HP Probook 4720. OS - Windows 7. P.S. Read an answer to a similar question: Annoying sound from microphone in headphone. Tried everything that was mentioned there. Only I don't have a "DC Offset Cancellation option". And when I disable "Noise Suppression" and "Acoustic Echo Cancellation", noise only becomes more noticeable. What should I do? EDIT: Example of the background noise I'm describing: http://eos-soft.com/files/noise.wma.

  • Change table view ( style grouped ) background color ?

    Hi all, I am developing an iPad application in which I need a table view ( style grouped ) having background color as clearColor. My problem is [self.tableView setBackgroundColor:[UIColor clearColor]]; works well if the table view style is plain but when I switch to group table view the background color does not changes it stays gray in color. FYI: the contentview background color of tableviewcell also does not change. Is this a bug in iPhone-sdk or I am doing something wrong. Thanks, Madhup

  • Gmail firing background tasks in Chrome and Firefox

    - by Keith Bloom
    I am experiencing a strange problem with Gmail running on Vista and it started when WindowsUpdate last patched my computer. Since then when Gmail is open in either Chrome or Safari the pointer changes to the Working in Background state every couple of seconds. You can imagine how distracting this is. I have never used Gmail in IE before so I loaded it up, Gmail wanted to load the GoogleTalk ActiveX control which I declined. Now Gmail in IE, I'm using version 8, didn't fire these background processes so I'm thinking it has something to do with GoogleTalk. Has anyone experienced this problem? Also does anyone know how to disable GoogleTalk in FireFox of Chrome.

  • Problem exporting NSOpenGLView pixel data to some image file formats using ImageKit & CGImageDestina

    - by walkytalky
    I am developing an application to visualise some experimental data. One of its functions is to render the data in an NSOpenGLView subclass, and allow the resulting image to be exported to a file or copied to the clipboard. The view exports the data as an NSImage, generated like this: - (NSImage*) image { NSBitmapImageRep* imageRep; NSImage* image; NSSize viewSize = [self bounds].size; int width = viewSize.width; int height = viewSize.height; [self lockFocus]; [self drawRect:[self bounds]]; [self unlockFocus]; imageRep=[[[NSBitmapImageRep alloc] initWithBitmapDataPlanes:NULL pixelsWide:width pixelsHigh:height bitsPerSample:8 samplesPerPixel:4 hasAlpha:YES isPlanar:NO colorSpaceName:NSDeviceRGBColorSpace bytesPerRow:width*4 bitsPerPixel:32] autorelease]; [[self openGLContext] makeCurrentContext]; glReadPixels(0,0,width,height,GL_RGBA,GL_UNSIGNED_BYTE,[imageRep bitmapData]); image=[[[NSImage alloc] initWithSize:NSMakeSize(width,height)] autorelease]; [image addRepresentation:imageRep]; [image setFlipped:YES]; // this is deprecated in 10.6 [image lockFocusOnRepresentation:imageRep]; // this will flip the rep [image unlockFocus]; return image; } Copying uses this image very simply, like this: - (IBAction) copy:(id) sender { NSImage* img = [self image]; NSPasteboard* pb = [NSPasteboard generalPasteboard]; [pb clearContents]; NSArray* copied = [NSArray arrayWithObject:img]; [pb writeObjects:copied]; } For file writing, I use the ImageKit IKSaveOptions accessory panel to set the output file type and associated options, then use the following code to do the writing: NSImage* glImage = [glView image]; NSRect rect = [glView bounds]; rect.origin.x = rect.origin.y = 0; img = [glImage CGImageForProposedRect:&rect context:[NSGraphicsContext currentContext] hints:nil]; if (img) { NSURL* url = [NSURL fileURLWithPath: path]; CGImageDestinationRef dest = CGImageDestinationCreateWithURL((CFURLRef)url, (CFStringRef)newUTType, 1, NULL); if (dest) { CGImageDestinationAddImage(dest, img, (CFDictionaryRef)[imgSaveOptions imageProperties]); CGImageDestinationFinalize(dest); CFRelease(dest); } } (I've trimmed a bit of extraneous code here, but nothing that would affect the outcome as far as I can see. The newUTType comes from the IKSaveOptions panel.) This works fine when the file is exported as GIF, JPEG, PNG, PSD or TIFF, but exporting to PDF, BMP, TGA, ICNS and JPEG-2000 produces a red colour artefact on part of the image. Example images are below, the first exported as JPG, the second as PDF. Copy to clipboard does not exhibit this red stripe with the current implementation of image, but it did with the original implementation, which generated the imageRep using NSCalibratedRGBColorSpace rather than NSDeviceRGBColorSpace. So I'm guessing there's some issue with the colour representation in the pixels I get from OpenGL that doesn't get through the subsequent conversions properly, but I'm at a loss as to what to do about it. So, can anyone tell me (i) what is causing this, and (ii) how can I make it go away? I don't care so much about all of the formats but I'd really like at least PDF to work.
