From: winapi on 20 Apr 2010 10:48 Hello, I have this "simple" example of a rebar control. I originally tried it in later versions of Microsoft Visual Studio C++, and for some reason the control is "not" displaying. I thought I would go back and try it in an earlier version of the Visual Studio, so I tried it in version 6, which is quite old now. The control "displayed" fine. I was wondering if someone might be kind enough to download the example from the link below, and maybe be able to tell me why it is not diplaying in later versions of visual stuido, 2008, and 2008 express editions. http://www.filedropper.com/rebarcontrol Thanks!

I located this file in the includes folder, and then replaced the "rebar section", with the one from visual studio 6. This seems to have fixed the problem, that is, it now displays.
From: Timo Kunze on 20 Apr 2010 12:53 Some struct definitions (I think REBARINFO was one of them) have been extended for Windows XP and Vista, so sizeof(<such a struct>) now returns something different than it did with the old definition. Depending on the version of Windows that you run the program on, this might be a problem. Commctrl.h contains some constants that can be used instead of sizeof() to keep compatibility.

I did think about the point you made, "after" I had changed that data in the "commctrl.h" header. I was wondering if you might be able to tell me some of the problems that could possible appear with updates for "sizeof(REBARINFO)"? I have been trying to follow the MSDN rebar example currently, and it does not seem to look like the one in their picture. The toolbar seems to sit over the combo box obscuring it from view. Also I can't seem to size the rebar control, it just assumes the "width" of the window on creation, or something of that manner. Maybe this is something to do with the "sizeof(REBARINFO)"? Do you know of any "simple" working examples? Thanks.

This is fixed now. It seems I was missing a few required styles for the "toolbar". |
