Visual C++ and MFC Programming 2nd Edition

Chapter 12: Dialog-Based Windows Visual C++ and MFC Fundamentals

12.1.4..Dialog Box Dimensions.....................................................................

The dimensions of a dialog box are its width and its height. At design time, to set the

desired width, position the mouse to its right border until the mouse pointer appears as a

horizontal double arrow Then click and drag left or right.

To set the desired height, position the mouse to the bottom border until the mouse cursor

appears as a vertical double arrow. Then click and drag up or down.

To set both the width and the height in one operation, position the mouse in the bottom-

right corner until the mouse pointer becomes a North-West – South-East diagonal double

arrow. Then click and drag up, down, left, or right as necessary.

While dragging in any of these operations, you can refer to the right section of the status

bar to get the current width and height. In the resource file, the width and the height of

the dialog box follow the location values. Here is an example:

IDD_SCHOOL_SURVEY DIALOGEX 0, 0, 340 , 268

There are other items that can be entered on this first line but the identifier, the

DIALOGEX statement, the location, and the dimensions are required.
