CB_GETLBTEXT notification to a program

Question

I'm trying to modify the selection of a particular combobox. I have already retrieved the handle successfully. However, when I call the function as below, I cannot modify the combobox selection properly:

r = SendMessage(cbox, CBN_SELCHANGE, 2, 0);

What would be the easiest method to accomplish what I want to do? Thanks in advance.

Answer 1

CBN_SELCHANGE is just a notification, it is sent via a WM_COMMAND message to the parent window when selection changes by the user.

CB_SETCURSEL is the message you need to use.

SendMessage(cbox, CB_SETCURSEL, 2, 0);

Should work.
