• .NET Development BinaryReader.PeekChar fails when checking for end of file

  VB.NET 2005 - Beta 2 I create a new filestream and then a binaryreader from that filestream.  I then loop doing a ReadByte until PeekChar = -1.  On one file in particular that I am reading, somewhere while reading the file (it may be at the end of file, but I am not sure) I get the exception message: The output char buffer is too small to contain the decoded characters, encoding 'Unicode (UTF-8)' fallback 'System.Text.DecoderRepla ...Show All

• .NET Development Just two true

  I noticed that true.ToString() Convert.ToString(true) Both return "True" rather than "true". Seems wrong to me somehow.....

• Game Technologies: DirectX, XNA, XACT, etc. Ways of Rendering mouse cursor in directx9

  I'm trying to build a GUI using directx 9. I find that rendering mouse cursor is something different from the main rendering process. It needs to have higher priority to make cursor looks "smooth" even when main rendering process's frame rate is low. Others give me some advice, but I'm not sure which is better. The following are the ways I figure out. 1. Using windows mouse cursor.  It's fast but in full screen mode it failed. 2. Draw ...Show All
