PRB: ShellExecute() Succeeds But App Window Doesn't Appear (124133)
The information in this article applies to:
- Microsoft Win32s 1.15
- Microsoft Win32s 1.2
This article was previously published under Q124133 SYMPTOMS
The following call to ShellExecute() succeeds and the file association
is set in File Manager, but the application does not appear to execute
(the window is not shown):
hShell = ShellExecute( hWnd,
NULL,
lpszFile,
NULL,
lpszDir,
SW_SHOWDEFAULT );
CAUSE
ShellExecute() is directly thunked to 16-bit Windows. Windows-based
applications do not support the SW_SHOWDEFAULT flag.
RESOLUTION
Under Win32s, use SW_NORMAL instead of SW_SHOWDEFAULT when using
ShellExecute() with a 16-bit Windows-based application. You can use
SW_SHOWDEFAULT if the application specified is a Win32-based application.
STATUS
This behavior is by design.
