When I pressed built button I found this message “The application or DLL C:\Visual C++\MSDev98\MyProjects\mophong\Debug\glut32.dll is not valid Windows image. Please check this against your installation diskette”.
My operator system is Windows XP Professional. What can I do ?.
Thanks for help

Which version of glut do u have? Earlier glut versions have conflicts with XP. I am not sure if this conflict has been resolved. The version of the dll might be your problem.
