I'm looking for the most efficient way to bind to these images on a Canvas control. These images are displayed side-by-side from a collection capped at 20 images. My current method does work ...
We are doing a simple service that changes the wallpaper when the phone (an SE xperia x10 mini) is tilted. So basically the code "almost" works - the problem is that the system does not appear to know that the system wallpaper have been changed or does not do anything about it. Starting and closing another app manually appears to enforce...

Background: I've created an online circuit design application where .draggable() div tags are containers that contain smaller div containers and so forth. Question: For any particular div tag I need to quickly identify if it contains other div tags (that may in turn contain other div tags). --> Since the div tags are draggable, in the ...

I am making a small game as sort of a test project, nothing major. I just started and am working on the graphics piece, but I'm not sure the best way to draw the graphics to the screen. It is going to be sort of like the old Zelda, so pretty simple using bitmaps and such. I started thinking that I could just paint to a Picture Box contr...

I want to start learning OpenGL but I don't really want to have to learn another language to do it. I already am pretty proficient in python and enjoy the language. I just want to know how close it is to the regular api? Will I be able to pretty easily follow tutorials and books without too much trouble? I know C++ gives better performa...
Some advice, please. I'm just starting out in C#. I've managed to get some shapes created on a Windows form, and now I'd like to fill them with color.

How would you go about mapping mouse coordinates to world coordinates in a 2d context? For example, you have an image which you can drag. Next, you apply a rotation to that image and redraw it. Now when you drag the image it does not get translated correctly. For example after rotating 90 degrees, dragging up would cause the image to t...
Which parts of pipelines are done using CPU and which are done using GPU? Reading Wikipedia on Graphics Pipeline, maybe my question does not precisely represent what I am asking. Referring to this question, which "steps" are done in CPU and which are done in GPU? Edit: My question is more into which parts of logical high level steps n...
