Resizable Dialog Box

CResizingDialog is a CDialog derived class that allows the dialog controls to be reordered
and resized with the Dialog Box.

To use CResizingDialog :

1. Replace the base class of your dialog box to CResizingDialog (instead of CDialog)
2. Change the dialog template to allow resizing border.
3. From the dialog constructor call SetConrolInfo() to set the behavior of
   each of your dialog controls on resize.

SetConrolInfo() determines how each control behaves when the user resize the dialog box.
The "Windows default" is ANCHORE_TOP | ANCHORE_LEFT) e.g.

For a right aligned OK button you’ll probably call:
SetControlInfo(IDOK, ANCHORE_RIGHT)
For a text control that needs to resize with the dialog you may do:
SetControlInfo(IDD_MYEDITOR, RESIZE_BOTH)
