Hopefully this is a simple question: How do I change the size of an undocked window (programmatically)? I have a window that is sub-classed from CExtResizableDialog. When the user undocks the window, it comes up with the correct size. However, when the user hits a button on the window, I would like the dialog to expand to twice it’s size (showing advanced options) (if the window is undocked).

I’ve tried the standard SetWindowPos and it doesn’t seem to work. Is there a method for doing this?

Any help is greatly appreciated.

Thanks for the code. The issue is still that I want to resize the dialog when it is not docked. The code shows the resizing when it is docked.

Excellent.. I read through the code (still didn’t work), but did notice something. The floating window that you change the size for is subclassed from CExtNCSB. We have version 2.80, rather than 2.84. From reading the help documentation, that class doesn’t seem to exist in our version. Is it possible to do it without the CExtNCSB, or do we have to upgrade?

The CExtNCSB template class replaces scroll bars of other window with the CExtScrollBar based themed Prof-UIS scroll bars. If you don’t need themed scroll bars, you don’t need the CExtNCSB template class. If you need themed scroll bars, then you need a newer Prof-UIS version because the CExtNCSB template class requires the newer CExtScrollBar class which requires the newer paint manager classes. The last classes require newer versions of mostly all the other classes. This template class is not related to the programmatic control bar resizing task. You can simply remove it if you have old Prof-UIS version. The sample application we improved for you does programmatic control bar resizing and it must work even with oldest Prof-UIS versions. Please describe us what you did after running the latest version of the test project referred in our previous answer.

Well, I figured out a solution. Not the most optimum, but works enough for me. It seems if I do:

            CSize szDialog(iWidth, iHeight);
            bar->SetInitDesiredSizeFloating(szDialog);
            bar->m_pDockSite->ShowControlBar(bar,false, false);
            bar->m_pDockSite->ShowControlBar(bar,true, false);

The dynamic change of the window works. I’m using version 2.80. If I just set the desired size for floating and called the recalclayout on the mainframe, nothing happened. In this situation, I get a flicker, but the user isn’t doing the auto-resizing all that often, so, it’s okay.

Please take a look at the following sample project:
