If you want to send a windows message to all instances of an application
(for example the WM_CLOSE message)
you can use this callback function

BOOL CALLBACK CloseAllWindowsByClassName(HWND Handle, LPARAM lParam)
{
    char WindowClassName[256] = {0};

    if (GetClassName(Handle, WindowClassName, 255))
        if (stricmp(WindowClassName, (char*)lParam) == 0)
            PostMessage(Handle, WM_CLOSE, 0, 0);

    return TRUE;
}



void __fastcall TForm1::Button1Click(TObject *Sender)
{
    // Select your Application
    //String WindowClassName = "Notepad";
    //String WindowClassName = "IEFrame";
    String WindowClassName   = "ExploreWClass";

    EnumWindows((WNDENUMPROC)CloseAllWindowsByClassName,
(LPARAM)WindowClassName.c_str());
}
