Dear Techies,

I am a newbie to MFC,and I've have similar kind of requirement related to Combo box.

1.The Objective is : The selected item(s) from 'X' Combo Box, then its corresponding Items must get on the 'Y' Combo Box.

(Assume that 'X' has internally some a,b,c,d..)if 'X' Combo box is dropped and 'a' is selected , the items under 'a' should be reflected to 'Y',I hope you've understood the objective.

2. And another one is from Transfering Items from One Combo Box to other List Box using the '>>' and '<<' buttons(ie from Right to Left and vice versa).

Pls guide me to accomplish this.

Regards,

MFC Techie.

Yes, both the Combo Box Controls are in a single Dialog Box. And I just need to associate two combo boxes.

Well, most controls in MFC are CWnd derived, that means that you can SendMessage() or PostMessage() between them if they have one another's handles. Alternatively, if you have a parent CDialog, he can act as the middle man and receive/each other's messages to/from controls.
