the author of this app says:
GeometryManager allows you to easily turn your fixed sized dialogs into resizable dialogs. It handles all the grunt work of resizing and moving the child controls in the dialog so you can focus on the functionality of your program. It also works in frame windows. It features a simple and powerful straight C API for the best compatibility. GeometryManager supports all versions of 32 bit windows, even Windows CE. Source code is available for purchase.
