Launch installed executable and set it to foreground window.

[Jiaquan Ma]

Greeting:

I have a function in my MSI custom action DLL that launches the installed
executable using ShellExecuteEx(). It launched the application
successfully, but the application window is on the background of the
Installer window. Is there a way to make it foreground instead?

Thanks a bunch.

Hi Jiaquan,

To bring a window to the front of other windows, we could call the Win32
API function 'SetWindowPos'.

The syntax of the function 'SetWindowPos' is like below:
BOOL SetWindowPos(HWND hWnd, HWND hWndInsertAfter, int X, int Y, int cx,
int cy, UINT uFlags);

To bring the window to the front of other windows, pass 'HWND_TOPMOST' to
the second parameter hWndInsertAfter.

For more information on the function 'SetWindowPos', you may visit the
following link.

Hope this helps.

If my suggestion is not propriate to your scenario, please feel free to let
me know.

Sincerely,

I am using:

SetWindowPos(ShExecInfo.hwnd, HWND_TOP, 0, 0, 0, 0, SWP_SHOWWINDOW);

At least it works on my development box. I will let you if it doesn't.
Meanwhile, please let me know if I am not using the correct switch for
hWndInsertAfter or uFlags. Otherwise, this problem should be addressed.

Thanks.

Hi Jiaquan,

Thank you for your response.

I notice that you pass 4 zeros to the SetWindowPos function. If you don't
want to change the current position and size of the window, you may pass 4
zeros as the third to sixth paramaters and specify
SWP_NOMOVE|SWP_NOSIZE|SWP_SHOWWINDOW as the last parameter.

Hope this helps.
