From: Nemo on 24 Apr 2008 12:03 Joe, Thanks for all the replies. My earlier question (as to why I am not able to find another instance to this problem) put me on the right track. It turned out that I wasn't configuring the control correctly in the resource file. For a multitude of reasons, the resource file is hand-edited for this project I am working on - and well, I obviously mucked my entry. Ajay, The reason I need the interface is that I wanted to insert an image in the control. The code is in KB I talked about in my first post.

This may create problems if you use resource editor. --- Ajay

From: Joseph M. Newcomer on 30 Apr 2008 09:04 For example, if you add a new radio button to a group, you have no choice but to hand-edit resource.h. If you rename an ID of a control, hand-editing the .rc file is often the most effective way. But note that all these hand-edits remain compatible with the resource editor. Doing hand-edits that are NOT compatible with the resource editor (such that if you ever edit the resources in the resource editor your application stops compiling) would be a Really Bad Idea. That's what the .rc2 file is for. joe On Wed, 30 Apr 2008 04:30:22 -0700, "David Ching" <dc(a)remove-this.dcsoft.com> wrote: >"Ajay Kalra" <ajaykalra(a)yahoo.com> wrote in message >news:7cd04a49-fb97-456b-b9f1-ba9aed760863(a)56g2000hsm.googlegroups.com... >> Hand editing of resource file doesnt sound good at all.
