PRB: Dialog Box and Parent Window Disabled (11337)
The information in this article applies to:
- Microsoft Platform Software Development Kit (SDK) 1.0
This article was previously published under Q11337 SYMPTOMS
When an application uses one of the DialogBox family of functions
to create a modal dialog box, both the parent window and the dialog
box are disabled (unable to accept keyboard or mouse input).
CAUSE
In the application's resource file, the dialog box resource has the
WS_CHILD style.
RESOLUTION
To avoid this problem, use the WS_POPUP style instead of the
WS_CHILD style.
MORE INFORMATION
When an application creates a modal dialog box using one of the
DialogBox family of functions, Windows disables the dialog box's
parent window. If the parent window has any child windows, the child
windows are also disabled.
An application can use the WS_CHILD style for dialog boxes created by
one of the CreateDialog family of functions. However, problems and
inconsistencies arise if the application uses the IsDialogMessage
function to process dialog box input for either the parent or the
child.
