IsPartialStringValidProposedSelectedRangeOriginalStringOriginalSelectedRangeErrorDescription Method (partialStringPtr, proposedSelRangePtr, origString, origSelRange, error)

This method should be implemented in subclasses that want to validate user changes to a string in a field, where the user changes are not necessarily at the end of the string, and preserve the selection (or set a different one, such as selecting the erroneous part of the string the user has typed).

Original signature is '- (BOOL)isPartialStringValid:(NSString **)partialStringPtr proposedSelectedRange:(NSRangePointer)proposedSelRangePtr originalString:(NSString *)origString originalSelectedRange:(NSRange)origSelRange errorDescription:(NSString **)error'

Available in Mac OS X v10.0 and later.

Declaration Syntax

Visual Basic

Visual C++

public virtual bool IsPartialStringValidProposedSelectedRangeOriginalStringOriginalSelectedRangeErrorDescription(
	out NSString partialStringPtr,
	ref NSRange proposedSelRangePtr,
	NSString origString,
	NSRange origSelRange,
	out NSString error
)

Public Overridable Function IsPartialStringValidProposedSelectedRangeOriginalStringOriginalSelectedRangeErrorDescription ( _
	<OutAttribute> ByRef partialStringPtr As NSString, _
	ByRef proposedSelRangePtr As NSRange, _
	origString As NSString, _
	origSelRange As NSRange, _
	<OutAttribute> ByRef error As NSString _
) As Boolean

public:
virtual bool IsPartialStringValidProposedSelectedRangeOriginalStringOriginalSelectedRangeErrorDescription(
	[OutAttribute] NSString^% partialStringPtr, 
	NSRange% proposedSelRangePtr, 
	NSString^ origString, 
	NSRange origSelRange, 
	[OutAttribute] NSString^% error
)

Parameters

partialStringPtr (NSString%): The new string to validate.

proposedSelRangePtr (NSRange%): The selection range that will be used if the string is accepted or replaced.

origString (NSString): The original string, before the proposed change.

origSelRange (NSRange): The selection range over which the change is to take place.

error (NSString%): If non-nil, if validation fails contains an NSString object that describes the problem.

Return Value

YES if partialStringPtr is acceptable, otherwise NO.
