SAMPLE: Code Demonstrates Changing Dialog Box Size

• Microsoft Windows Software Development Kit (SDK) for Windows versions 3.1 and 3.0

The Color dialog box provided by the COMMDLG dynamic-link library (DLL) expands to show additional controls when the user chooses the Define Custom Colors button. The XPANDDLG sample application in the Microsoft Software Library demonstrates how an application can implement similar behavior.

Download XPANDDLG.EXE, a self-extracting file, from the Microsoft Software Library (MSL) on the following services:

• Microsoft Download Service (MSDL)

        Dial (206) 936-6735 to connect to MSDL
        Download XPANDDLG.EXE (size: 24114 bytes) 
  

• Internet (anonymous FTP)

        ftp ftp.microsoft.com
        Change to the \SOFTLIB\MSLFILES directory
        Get XPANDDLG.EXE (size: 24114 bytes) 
  

1. Create the dialog box at its large size.

2. Call the MoveWindow() function to size the window to the smaller size when the dialog box procedure receives a WM_INITDIALOG message.

3. To show the remainder of the dialog box on the screen, call MoveWindow() again.
