Help required to send keys for Windows mobile

I'm Rajashekhar and newfor the Python CE on the windows mobile environment.
I have HTC mobile and i have installed the PythonCE 2.5 uisng the PythonCE.WM.CAB from http://ftp.heanet.ie/disk1/sourceforge/p/py/pythonce/.

I'm writing some scripts on python to invoke particular applications from idle screen and send keys to do action related to those keys.
for e.g When i execute the Python scripit it should open the calendar by sending Left Soft Key(LSK) and it has to open Menu if i send Right Soft Key(RSK).
Here, I'm facing one problem related sending the keystrokes, how can i send the keystokes from pyton scripts ?

Any modules which are there for windows mobile, if it is there please mention where can i get it.

And also I have few source files written in C language to do the above functionality, how can I build these to .pyd for windows mobile environment.
Any ideas or suggestion please let me know.
