Description

Limits the amount of text a user can enter into the RichEdit control.

Syntax

void LimitText( long nChars = 0 )

Parameters

nChars: Specifies the length (in bytes) of the text that the user can enter.; If this parameter is 0, the text length is set to UINT_MAX bytes. This is the default behavior.; Remarks; Call this function to limit the length of the text that the user can enter into an edit control.; Changing the text limit restricts only the text the user can enter. It has no effect on any; text already in the edit control, nor does it affect the length of the text copied to the edit; control by the Text member function in Window. If an application uses the Text; function to place more text into an edit control than is specified in the call to LimitText,; the user can delete any of the text within the edit control. However, the text limit will; prevent the user from replacing the existing text with new text, unless deleting the; current selection causes the text to fall below the text limit.

Return

None.
