press start bot programmaticaly

[zzzar 13]

Hello, i make own lightweight lame logger/relogger and stuck at press "Start" button of bot.

at first SetForegroundWindow(p.MainWindowHandle); // focus bot window

then i try various ways

1) SendKeys.SendWait("%(c)");

2)         keybd_event(0x12, 0, 0x02, UIntPtr.Zero); // press alt
            Thread.Sleep(1000);
            keybd_event(0x43, 0, 0x02, UIntPtr.Zero);  // press c
            Thread.Sleep(400);
            keybd_event(0x12, 0, 0x00, UIntPtr.Zero); // unpress alt
            keybd_event(0x43, 0, 0x00, UIntPtr.Zero);  // unpress c

3) even try to tab between bot window elements

but none work, like keys not send to window, but tested on notepad and it works . Is there way to press start button?
