Basically because my code could return either an image or an error, assigning it to an image property when the method is called will not work. Is the approach I'm using wrong in the method declaration of the class, or should I be calling the method differently to anticipate potentially differing results? Thanks public class UtilitiesService: NSObject { public class func loadImage(urlString:String) { var imgURL: NSURL = NSURL

I'm writing a function that quickly draws an image of a menu for a game I'm making. I'm able to draw the background and text blocks just fine but I'm having trouble creating a bitmap image on the screen bool menu::drawMenu(PAINTSTRUCT ps) { HWND hWnd = GetActiveWindow(); HDC hdc = GetDC(hWnd), hdcMem; //Draw a new background HPEN blackPen = CreatePen(PS_SOLID, 1, RGB(0, 0, 0)); HBRUSH blackBrush = CreateSolidBrush(RGB(0, 0, 0)); SelectObject(hdc, blackPen); SelectObject(hdc, blackBrush); Rectangle(hdc, 0, 0, 1080, 720); //insert selection text TextOut(hdc, 30, 0, L"New Game", 8); TextOut(hdc,

I need to display 16x16 pixel icons for error/warning/information. Unfortunately both LoadIcon(0, IDI_*) and LoadImage(0, OIC_*, IMAGE_ICON, 16, 16, LR_SHARED) always give me the 32x32 version of the icon. I read about ShGetStockIconInfo but that is only available from Vista onwards and I still need to support XP. Any ideas? I'm using Delphi 2010 with a TImage component if that matters. The problem is that when you do it this way you get a cached version of the icon, the first one that the system loaded. That will be the large sized icon, typically 32x32. It matters not what size you specify.

I am trying to create a "map of a city" using pygame. I want to be able to put images of buildings in specific grid coords rather than just filling them in with a color. This is how I am creating this map grid: def clear(): for r in range(rows): for c in range(rows): if r%3 == 1 and c%3 == 1: color = brown; grid[r][c] = 1; else: color = white; grid[r][c] = 0; pygame.draw.rect(screen, color, [(margin+width)*c+margin, (margin+height)*r+margin, width, height]) pygame.display.flip(); Now how do I put images of buildings in those brown colored grids at those specific locations? I've tried some of

I want to load 4 images from background showing a load bar to the client and when the images will be downloaded i want to set them as background images to 4 div blocks. I am looking for something like this. var myImages = new Array(); for(var i = 0; i < 4; i++) myImages[i] = new Image(); //load images using the src attribute //and execute an on load event function where to do something like this. var div0 = document.getElementById('theDivId'); div0.style.backgroundImage = myImage[index]; Is there any way to set a background image using an Image javascript object? You can do something close to

I want to load an image into a PictureBox . This is the image I want to load: http://www.gravatar.com/avatar/6810d91caff032b202c50701dd3af745?d=identicon&r=PG How do I do this? The inbuilt PictureBox.Load(string URL) Method "sets the ImageLocation to the specified URL and displays the image indicated." (Since .NetFramework 2) Try this: var request = WebRequest.Create("http://www.gravatar.com/avatar/6810d91caff032b202c50701dd3af745?d=identicon&r=PG"); using (var response = request.GetResponse()) using (var stream = response.GetResponseStream()) { pictureBox1.Image = Bitmap.FromStream(stream); }

I have an activity, which has a button. When I click on the button it redirects me to the image gallery. I want to show the selected image in the next activity using an image view. But it is not displaying the image. The view is off screen when the image is set. My code for selecting image and moving on next is given below. I am using no history true in my activities. @Override protected void onActivityResult(int requestCode, int resultCode, Intent data) { super.onActivityResult(requestCode, resultCode, data); if (requestCode == RESULT_LOAD_IMAGE && resultCode == RESULT_OK && null != data) {
