Form.Desiginer.vb files are new to net 2.0 (VS 2005) they contain the auto generated code caused by draging things onto the designer and manipulating their properties. it's the equivilant to to the "Windows Generated Code" region of a VS 2002 or 2003 Form. Typically only changes made to the designer get written to this file. you may have botched a property. try importing the lib desire. copy local = false is fine for system namespaces, since they are part of the core framework (%windir%\Microsoft .Net\Framework\-VerNum-\). you only need copy local when your referencing a custom or third-party lib. Good luck hey...slang is the vernacular for the vernacular...wow

In the tab control use the tabs collection like tabl(0) to enable or disable any tab on appropriate time/action you want to perform. you can even set the visibility as well and any other action. Regards, Asim
