   worked in 2000, crashes in XP
  Sorry, this is very general, but I develop in Windows 2000 and everything tests fine.  But then I run the program in XP and it crashes with not much info.Does anyone have a sugestion of what could be wrong here?Any basic rules for developing for XP??thanks for any help.  
  Are you using XP home? because i have heard that that version has some bugs when it comes to directx and programming   ;  Run it in the debugger and show us the section of code where it crashes.  There''s really no other way to tell.  ;  hmm, ok, yeah I don''t have an XP dev box, it was on a friends XP box, so I can''t debug it on his machine.  oh well.If anyone else has a sugestion, I''m all ears.Thanks for the replies.  ;  What crashes? The program? The whole machine?What does the program do, what libraries, APIs etc. does it use?When does it crash? What''s it trying to do when it crashes?Can''t really say why something crashes without at least some of those answers.  ;  At what point does it crash? Does it at least start up?Does it crash when something in particular happens?Is it a large program or something little?What does the program do?Are you using DirectX or OpenGL?Do you assume that the DC will be created correctly?Are there files missing which you are assuming have been opened correctly?etc.etc.etc.etc.This is what people are paid lots of money to do.You''ll have to be far more exact and do the hard work for us.
