HOWTO: Switch Between Single and Multiple List Boxes

• Microsoft Windows Software Development Kit (SDK)
• Microsoft Win32 Software Development Kit (SDK)

SUMMARY

After you create a list box with the CreateWindow() API, you can change the list box from a single selection to a multiple selection by doing the following:

1. Create two hidden list boxes in the .RC file.



2. During the WM_INITDIALOG routine, display one of the boxes.



3. Change between the two by making one hidden and the other one visible using the ShowWindow function.
