Send key strokes to control

I have a WinForm laid out as a keyboard.  This form gets shown as a dialog when I Enter certain controls on a another form.

I pass references to both the parent form, and the actual control to the keyboard form, with the intention of programatically send key stroke to the control.

I tried using the contro.SelectedText = "x" approach, and that works great for the text or pure integer controls, but it doesn't work on decimal or currency type fields.  

So recently I have been looking at SendKeys.Send(), and even PostMessage(), but in both cases, whilst the code appears to run, nothing appears in the control.

Now I would have thought it would be pretty easy to send keystrokes to a control, when you already have a reference to that control, but this problem eludes me.

Can anyone suggest a simple foolproof way to do this.

Thanks

I have found the solution, turns out, as I half expected, to be really easy.  The controls have the Handle parameter, I just used this handle with the PostMessage method.
