Chapter Nine — Dialog Functions (continued)
Overview
The ControlUpdate function forces a control to update its status and paint.
Syntax/Parameters
Syntax
int = ControlUpdate ( int id, [boolean erase] );
Parameters
id
An int that identifies the dialog control to update.
erase
An optional boolean parameter that tells Windows to erase the background and start over with painting. This will remove any painting errors or artifacts but may also cause flicker when repeatedly called. In addition, repainting is an expensive operation with respect to processing.
Return Value
An int specifying ERROR_NONE (0) on success, ERROR_RANGE on bad control ID, or ERROR_INVALID_HANDLE.
Remarks
When performing long sequences of processing within a dialog, the action of setting control data may not update in a timely manner. This function forces an update.
This function can only be used within a dialog procedure. If a dialog page is not active, the function will fail.
