Radio Button Problem

[KimiSue]

Myy roomate and I have a problem that in driving us INASANE! We have a search screen that comes up, has a text entry box for the search criteria, and 2 radio buttons - by name or by i.d. We have tried all we can find in books or think of to get the code written to distinguish between the 2 radio buttons. Does anyone have any ideas, please? Thanks!

Well.... It depends on what compiler you are using, and how your radio buttons are created.<br>
If you are using a Resource compiler, you would assign an ID to each radio button and simply check for that ID against the "wParam" variable of the "WM_COMMAND" message for the window that owns the radio buttons.<br>
Kind of like this:<br>
In your RESOURCE file (This is a paste from some of my working code of a dialog box with radio button controls. Borland C++ 3.1):<br>
<br>
MyPortSetup DIALOG 25, 16, 174, 179<br>

I hope this helps.

Thank you so much - it was just one little detail piece that I couldn't seem to find. I REALLY appreciate your help!
