The program works in compatibility mode

Question

Is there a C ++. NET function that I can call that will detect if my program is running in compatibility mode? If not, can someone show me the code for one? Thank.

For instance:

Download programs Check compatibility mode if true, then exit else run

Answer 1

From another forum

After several Google searches in vain, I decided to experiment myself. I found that compatibility for each executable is stored - as I thought it would be - in the Windows registry.

The key in which the settings are stored is
HKEY_CURRENT_USER \ Software \ Microsoft \ Windows NT \ CurrentVersion \ AppCompatFlags \ Layers

, , - , - .

, : WIN95 WIN98 NT4SP5
WIN2000 256COLOR 640X480
DISABLETHEMES DISABLECICERO
