I want to write a small app for windows 98, 95, and NT, that will automatically change the screen resolution.
Probably in Visual c++
Requirements:
- no restarts
- no prompts
- just changes the resolution when run
Can anyone help please?

Give this a try.

BOOL EnumDisplaySettings(LPCTSTR pszDeviceName, DWORD iModeNum, PDEVMODE lpDevMode);

Sorry, use

EnumDisplaySettings(LPCTSTR pszDeviceName, DWORD iModeNum, PDEVMODE lpDevMode);

to get the current and supported settings, then use

 LONG ChangeDisplaySettings(LPDEVMODE lpDevMode, DWORD dwflags);

To change the setting.

You can simple change resolution
and launch Apps:
To get current resolution:

int cx = GetSystemMetrics(SM_CXSCREEN),
cy = GetSystemMetrics(SM_CYSCREEN));

To change resolution:
  DEVMODE dm; dm.dmPelsWidth=cx; dm.dmPelsHeight=cy;
  dm.dmSize = sizeof(dm);
  dm.dmFields = DM_PELSWIDTH | DM_PELSHEIGHT;
  ChangeDisplaySettings(&dm, 0);
