nkasseinov posted a topic in For BeginnersI am a beginner to Direct3d and I was playing around with some of the tutorials on the link below: https://code.msdn.microsoft.com/windowsdesktop/Direct3D-Tutorial-Win32-829979ef For about week, I have been working with these tutorials and everything seemed to be running ok. Yesterday, however, all of the programs stopped working, even the ones I didn't touch. What happened was that the window created by the program to display the image would immediately close upon opening. I eventually deleted these files and re-downloaded them from the same link, but the problem persisted. I was wondering if anybody has any ideas as to what is going on here?
