RobotStudio event

Problems with FlexPendant SDK and Visual studio!!!

I'm going to develop an application for flexpendant. I have installed the flexpendant SDK program correctly. When I go to open a new project and click to SmartDevices, the flexpendant no appears. I have tried with some different versions of visual studio  (2005,2008,2010) and all the versions of flexpendant SDK. I don't have installed RobotStudio , I only have installed SDK Flexpendant. Can someone help me? I need a solution. It's too important.

 

Thank you.
