Direct X Basic Window Help

[Zvjezdan23]

This is code for building a white window in direct X. The problem is, when I debug, I get this error.

'Chapter1_DirectXWindow.exe': Loaded 'C:\WINDOWS\System32\uxtheme.dll', Cannot find or open the PDB file

The program '[2536] Chapter1_DirectXWindow.exe: Native' has exited with code -1 (0xffffffff).
