  • SetScrollPos: scroll bar moving, but control content not updating

    - by sniperX
    [DllImport("user32.dll")] public static extern int SetScrollPos(IntPtr hWnd, int nBar, int nPos, bool bRedraw); [DllImport("user32.dll", CharSet = System.Runtime.InteropServices.CharSet.Auto)] public static extern int GetScrollPos(int hWnd, int nBar); So those are the externs im using to move the scroll position, what im doing, is i get the current position, and add or substract an exact amount of pixels, and the scroll bar on my form moves perfectly how i want it, but the content in the control stays stationary. What is the problem here?

  • segemented control in iphone not appearing as in interface builder

    - by zecougar
    here is what i see in IB and here is what appears in the simulator i've used a segmented control with style = "Bezelled". When i change the style to "Bar", IB and simulator are consistent in the display. the style is set in interface builder and not in code, if that matters Also - the edges look rather ugly in the simulator. not what i expected even when it rendered incorrectly. Thanks in advance

  • CF - How to "lose" focus from a control

    - by no9
    Hello. I have a control with two buttons (zoom in, zoom out). Both buttons have onClick event that handle the zoom. When any of the button is pressed, the button gets focus and bolds its border and text. Is there a way to disable/remove focus? Actually the solution im looking for would be that on mouseDown the button would receive focus and would lose it on mouseUp. thanx !

  • How to load image in correct pixel depth

    - by extropy
    I have a bunch of monochrome (1bpp) PNG images I want to load, and pass to pdfSharp. Using Image.FromFile loads images fine, but it alawys uses 32BPP, regardless of the pixel depth of the file. That results in very large PDF files generated. Is there a way to load images in their native pixel depth?

    - by I'm Dario
    I'm working with a shell account in a shared system and I would like to use some version control software for my bash scripts and config files. It must works on Linux with no dependencies, just unpack it in my home dir. I don't need remote checkout, branching or other fancy tricks. I want to be able to commit my changes and restore them if needed.

  • Missing part of the image when taking screenshot while supporting Retina Display

    - by Spaft
    I'm currently working on enabling support for retina display for my game. In the game, we have a feature that the user can take screenshot. We are using these part of code we found online a while ago and it's working fine when we are not supporting retina display: CCDirector* director = [CCDirector sharedDirector]; CGSize size = [director winSizeInPixels]; //Create buffer for pixels GLuint bufferLength = size.width * size.height * 4; GLubyte* buffer = (GLubyte*)malloc(bufferLength); //Read Pixels from OpenGL glReadPixels(0, 100, size.width, size.height, GL_RGBA, GL_UNSIGNED_BYTE, buffer); //Make data provider with data. CGDataProviderRef provider = CGDataProviderCreateWithData(NULL, buffer, bufferLength, NULL); //Configure image int bitsPerComponent = 8; int bitsPerPixel = 32; int bytesPerRow = 4 * size.width; CGColorSpaceRef colorSpaceRef = CGColorSpaceCreateDeviceRGB(); CGBitmapInfo bitmapInfo = kCGBitmapByteOrderDefault; CGColorRenderingIntent renderingIntent = kCGRenderingIntentDefault; CGImageRef iref = CGImageCreate(size.width, size.height, bitsPerComponent, bitsPerPixel, bytesPerRow, colorSpaceRef, bitmapInfo, provider, NULL, NO, renderingIntent); uint32_t* pixels = (uint32_t*)malloc(bufferLength); CGContextRef context = CGBitmapContextCreate(pixels, size.width, size.height, 8, size.width * 4, CGImageGetColorSpace(iref), kCGImageAlphaPremultipliedLast | kCGBitmapByteOrder32Big); CGContextTranslateCTM(context, 0, size.height); CGContextScaleCTM(context, 1.0f, -1.0f); switch (director.deviceOrientation) { case CCDeviceOrientationPortrait: break; case CCDeviceOrientationPortraitUpsideDown: CGContextRotateCTM(context, CC_DEGREES_TO_RADIANS(180)); CGContextTranslateCTM(context, -size.width, -size.height); break; case CCDeviceOrientationLandscapeLeft: CGContextRotateCTM(context, CC_DEGREES_TO_RADIANS(-90)); CGContextTranslateCTM(context, -size.width, 0); break; case CCDeviceOrientationLandscapeRight: CGContextRotateCTM(context, CC_DEGREES_TO_RADIANS(90)); CGContextTranslateCTM(context, size.width * 0.5f, -size.height); break; } CGContextDrawImage(context, CGRectMake(0.0f, 0.0f, size.width, size.height), iref); UIImage *outputImage = [UIImage imageWithCGImage:CGBitmapContextCreateImage(context)]; //Dealloc CGDataProviderRelease(provider); CGImageRelease(iref); CGContextRelease(context); free(buffer); free(pixels); return outputImage; But when we enabled retina display in cocos 0.99.5. This functionality is a little messed up since it will miss a little left part of the image while the high is still correct. So I'm wondering if there is anything wrong with the code or am I doing anything wrong here? Thank you in advance for any reply!

  • open source custom tooltip (callout) control/code for asp.net

    - by dotnetcoder
    Looking for a custom tooltip (typical yellow baloon callout) on click of an anchor tag. The tooltip should appear and remain in view until the cross button on the tooltip is clicked. Just looking for a tried and tested open source solution. Tried googling this but most of the tooltip [...missing info?...] Ajax control toolkit has the calloutvalidator which seems like a good choice but is tied up to be used for validation tooltips.

  • Build a custom drawn control for .net compact framework

    - by Hinek
    I just started on the .net compact framework. I want to draw a Sudoku field on the screen. So I put down a PictureBox and defined a method for the Paint event: private void pictureBoxPlayfield_Paint(object sender, PaintEventArgs e) { // use e.Graphics to draw the grid, numbers and cursor } This works, but you can see as the grid is drawn. So my question is, what is the right/better way to create such a custom control? Is there maybe a way to enable double buffering?
