GetSystemMetrics(SM_CMOUSEBUTTONS) Fails Under Win32s

Last reviewed: February 24, 1995
Article ID: Q124836

The information in this article applies to:

Microsoft Win32s versions 1.15, 1.15a, and 1.20

Under Win32s, the Win32 API GetSystemMetrics() is implemented as a direct thunk to Windows version 3.1. Therefore, the call will return whatever Windows version 3.1 would return for a similar call to the Windows API GetSystemMetrics().

GetSystemMetrics() returns zero for all unrecognized parameters. Under Windows, this includes the new flag SM_CMOUSEBUTTONS, which was introduced in the Win32 API. Therefore, avoid using the SM_CMOUSEBUTTONS flag when your Win32-based application is running under Win32s.
