NoteBox.jpg

This template (and its associated code templates) has been deprecated, and is now replaced by the RTF Text Control template.

The CanUndoRTF code template checks the RTF control to see if there is data in the undo buffer. A TRUE value is returned if an undo can be done. A FALSE value is returned if there is no undo data in the buffer. This template calls the Undo method.

Prototype:

CanUndo

Return Data Type: BYTE

 Example method calls:

loc:undo = oRTF_RTFTextBox.CanUndo() !Check for data in the Undo buffer

Template Prompts:

Associated RTF control

Select the RTF control from the drop-down list. All controls on the Window are included in the list. This field in required.

Variable to receive Undo Status

Press the ellipsis button (') to choose a variable to receive the return value from the method.
