Hello

I'm writing an application for a PDA;

    * OS: Microsoft Windows Mobile 5.0
    * lang: C# .Net 2.0
    * IDE: Microsoft Visual Studio 2005

I wanted to override the green "call" button of the PDA. So the cprog.exe (default phone application does not launches. This succeeded using this code:


long res = SendMessage(SHFindMenuBar(this.Handle), SHCMBM_OVERRIDEKEY, VK_TTALK,
                (SHMBOF_NODEFAULT | SHMBOF_NOTIFY) | (SHMBOF_NODEFAULT | SHMBOF_NOTIFY) << 16);


and

...
 if (m.Msg == WM_HOTKEY)
                {
                    int key = m.LParam.ToInt32() >> 16;
                    switch(key)
                    {
                        case VK_TTALK:
                            MessageBox.Show("CLICK");
                            break;
                    }
                }
...

But once my application is minimized (thus still running on the background), the function of the "call" button hotkey is no longer triggerd and overridden by my application...

Is there a solution for this problem?

Kind regards and thanks for your effort
