MFC and Tab controls
Author
Hi
I want to build a dialog with a tab control in it.
I''we derived my own classes from CPropertySheet and CPropertyPage and got it to work. The problem is that now when I''m going to update and/or store data in the pages things grow more and more complex.
Therefore I want to use a simple CTabCtrl since I think it would fit better with what I want to do.
Can I add pages as resources into my tab control in a similar way as with the property control or do I have to build all the pages on top of the tabcontrol and activate/show the different things that shall be on that page?
The last thing feels like a big no-no...
Any sugestions?
Thanks

I build my own tab pages in resource editor and activate ie. show/hide them in code. I tried using the property sheet but that''s only for dialog boxes, my tabs are embeded inside my control panel in an editor. You need to shrink the dlg boxes that make up your pages when you add more tabs otherwise the dlg boxes get pushed down and some text/controls might not be visible. I resize them in resource editor, though I think you can do it in code as well, but then you need to resize controls in code as well. In MFC, you need to pass in parent dlg box pointer that houses the tabs and pages to each child page, I think to get the ownership working.

Hmmm... so you are using a new dialog for each page in your tab control? Did I got that correct?
My tabctrl is in a dialog, but I think it''s best if I build it by my own anyway and not using a property sheet.
Do you have to build your own handler that changes the pages? (I guess I have).
Thanks

Yes, I build new dlg resource for each tab. I have written my own handler that switches between the pages. Here''s the code:
CtrlPanel
One page in ctrlpanel:
