There appears to be a difference in physically clicking a button with the mouse, and doing it programmatically, as in thisform.thatbutton.click. Can anyone please explain this to me?

I have a textbox that a search string is typed into. To make it more convenient for the user, so they don't have to actually use the mouse, I have the following in the KeyPress method:

IF nKeyCode=13 &&the 'enter' key
	thisform._searchcmd.Click
ENDIF

The code in thisform._searchcmd.click is accessed, and run, but the cursor holding the SQL Select(ed) data is empty. Physically click the _searchcmd button, and the data is there...

Thanks.
