First, need to find the handle of the Control by using some API like EnumWindows and enumerrating all windows and checking for the text of the window by GetWindowTExt.
Once, handle of the target control has been identified, SendMessage can be used to send appropriate message to the control. like WM_SETTEXT can be sent to change text of window, etc...

Answer / bhaskaraiah

To get/set the data of edit control of another running
application you need to get the control ID of the edit
control.This can be obtained by using the "spy++" tool of
visula studio tools.Then use PostMessage to send WM_SETTEXT
meesage to it.
