Description
Validates a specified string against the current mask.
The ValidateEdit method calls Validate to perform the actual validation of the current text against the edit mask. It returns True if the string specified by Value
is consistent with the edit mask, and False if it detects an invalid character. If ValidateEdit returns False, it returns the position of the invalid character as the Pos
parameter.
