keybd_event not firing OnKeyPress callback method

I have a form that overrides the OnKeyPress() / OnKeyUp() / OnKeyDown() methods.

When I do a P/Invoke call to keybd_event() it does not make it into these methods. Here is my P/Invoke:

public const int KEYEVENTF_KEYUP = 2;
public const int VK_RETURN = 0x0D;

public void pressEnterKey()
{
//press the enter key
keybd_event(VK_RETURN, 0, 0, 0);
//releasethe enter key
keybd_event(VK_RETURN, 0, KEYEVENTF_KEYUP, 0);
}

Is this a threading issue

Thanks,

What platform are you seeing this issue on

Try to see if you get the same issue with another Key e.g. Shift Key, or the arrow Keys.

I'm in Windows Mobile 5. I've tried many keys. None of them work. I'm invoking this in a unit test helper class that is running outside the GUI thread, so I believe that it's not firing the event correctly back to the form. Someone told me that I should use a BeginInvoke() to resolve this, but I'm not sure how to do that in the proper way.

Any ideas

Thanks,
