• Windows Forms Image display form....some questions

  I've written a very simple form that loads an x number of images from a local directory and displays each bitmap in picture boxes. The result is that each image is displayed one row at a time. I don't like the way the images are currently being displayed. Is there some kind of formula I can use to display them in rows of 5 at a time There could be anywhere from 50 images to 500 images being loaded at a time. I don't want the images to be displayed one row at a time like it is right now, but i can't quite figure out how to come up with the correct row and column offset numbers when setting the location for each picture box. thanks in advance!

• Game Technologies: DirectX, XNA, XACT, etc. memory leak

  My game slows down to a creep and eventually its using 100% of resources for a simple 2d game. ...I'm thinking it must be a memory leak. Being relatively new to C# and XNA, what is the best way to find and kill the leak C# is all about garbage collection, some of C# is built on COM and win32 etc, this can leak. However components built on these thing usually implement the dispose pattern. Components that use this pattern have a Dispose() method you should call, this will do a proper release of these resources. The gabarge collector will release those resources also it will dispose also, but you cannot guarentee when garbage collection will happen. C# has the handy using keyword (not the same as t ...Show All

When the advanced options button is clicked you can show a PopUp which contains a StackPanel of other actions as buttons. HTH, Drew ...Show All
