if (bFound)
{
if (it's a popup window)
SetForegroundWindow(handle to the popup window);

if (it's an icon)
    ShowWindow(handle to the popup window, SW\_RESTORE);

return FALSE;

}

oh sorry, i didn't understood your *code* at first time. DavidCrow wrote: SetForegroundWindow(handle to the popup window); ShowWindow(handle to the popup window, SW_RESTORE); hum well, how do you get handle to the popup window ?

This is how I limit my apps to a single instance and activate the first instance if another is run. HANDLE hm = CreateMutex(NULL, TRUE, "Mutex Name"); DWORD dw = GetLastError(); if(dw == ERROR_ALREADY_EXISTS) { SetForegroundWindow(FindWindow("ClassName", "WindowName")); return(0); } There are probably better ways but this is the simplest I know and has always worked just fine.

interesting code. but what do ClassName and WindowName represent exactly in your above line code ?

SetForegroundWindow(FindWindow("ClassName", "WindowName"));

thanks in advance.

ClassName is the name of the type of class of the window you are looking for. Such as the name you used when you called RegisterClass. WindowName is the name of the window you wish to find. This is the window title. Such as "The Code Project - Free Source Code and Tutorials - Internet Explorer". Read the MSDN entry for FindWindow, that should explain it better than me. Hope this is helpful.
