Well the original content of this message was why ActiveX Forms.ScrollBar do not react to when I resize the form width but when both height and width it resize and even I put a code in a resize so that It will react to the resizing but still no response.

Resize Methods: (DO NOT WORK)
Local cNams, oObject

cName = "This.Parent.V" + This.Name
If Type(cName) == "O"
oObject = &cName
oObject.Left = This.Left + This.Width
EndIf

Resize Method: (WORK FOR ME)
Local cNams, oObject

cName = "This.Parent.V" + This.Name
If Type(cName) == "O"
oObject = &cName
oObject.Visible = .F.
oObject.Left = This.Left + This.Width
oObject.Visible = .T.
EndIf
