I wish to write an MDI application which upon starting up, a workspace window will appear on the left of the main frame. I tried to use  CDialogBar class to implement. It works well except I could not resize it.

Will anyone tell me how to around this problem ?

Thank you all

To resize the dialogbar, obtain a pointer to it and then use the MoveWindow() function.

Because CDialogBar is a window, you can use SetWindowPos to rsposition or move.

You can add splitter window. Your DialogBar is inserted left one. When drag split border,
you should resize DialogBar height. Thus you can imitate resizing function.

Have tried to use MoveWindow and SetWindowPos but they did not work as expected.

Note that MoveWindow has a strang way of passing params:
The first two are coordinates, while the following are not! they specify widh and hight.
Check if you passed params correctly, i hope this helps.

Here is some information that might help.
To make a dialog bar resizable:

1.Use the new CBRS_SIZE_DYNAMIC style when creating the dialog bar.

2.Add code to an override of the new CalcDynamicLayout() function.

Control bars support the new CBRS_SIZE_DYNAMIC style. CBRS_SIZE_DYNAMIC allows a floating control bar to be dynamically resized when the user drags the control bar's border. The virtual function
CControlBar::CalcDynamicLayout() has been added to determine the size that a control bar should be resized to.

CalcDynamicLayout() is called for CBRS_SIZE_DYNAMIC control bars when the border of a floating control bar is dragged and when the control bar is docked or floated. The default CControlBar implementation simply calls CalcFixedLayout(), which prevents control bar objects from resizing unless CalcDynamicLayout() is overridden. CDialogBar does not override CalcDynamicLayout(), so by default, dialog bars are not resizable.

To make a resizable dialog bar:

1.Create a new class derived from CDialogBar and override the CalcDynamicLayout() function. Depending on the behavior you
want, it may be necessary to add a member variable to the class.

2.Create an instance of this class using the CBRS_SIZE_DYNAMIC style bit. Dialog bars are typically created in
         CMainFrame::OnCreate():
         if (!m_wndDialogBar.Create(this, IDD_DIALOGBAR,
         CBRS_TOP | CBRS_SIZE_DYNAMIC, 777)) {
            TRACE0("Failed to create dialogbar\n");
               return -1;
      }
      m_wndDialogBar.EnableDocking(CBRS_ALIGN_ANY);
        DockControlBar(&m_wndDialogBar);

Hope this helps
thanks
