ich habe im projekt quellcodes folgendes stehen:

WINAPI WinMain(HINSTANCE, HINSTANCE, LPSTR, int)
{
        Application->Title = "";
        HWND hPrevApp = ::FindWindow(NULL, "Mein Title");

        if(hPrevApp)
        {
           PostMessage(hPrevApp, WM_SYSCOMMAND, SC_RESTORE, 0);
           return 0;
        }
        // else: other instance not found, restore the title and continue
        else
           Application->Title = "Mein Title";

        try
        {
                 Application->Initialize();
                 Application->Title = "Mein Title";
                 Application->CreateForm(__classid(TForm1), &Form1);
                 Application->Run();
        }
        catch (Exception &exception)
        {
                 Application->ShowException(&exception);
        }
        return 0;
}

Meine Anwendung nutzt das Tray Icon und nun möchte gerne, sofern die Anwendung schon geöffnet ist, einfach TrayIcon1->Restore() aufrufen, da mein jetziger code dies nicht macht.

Oder hat jemand ne andere Idee?

			SetForegroundWindow(hPrevApp); // kein schöner Stil, aber bringt das Fenster in den Vordergrund...
