Using VB.NET to insert Solidworks Part

Hey Everyone, I have a question regarding the code used in VB.NET to insert a part into Solidworks. I've been able to setup the basic dialog boxes in Visual Studio that are triggered when someone clicks the Launch button on the task pane in the Solidworks main program. But actually getting Solidworks to insert a part has got me stumped so far. Any help on this would be awesome. Thanks again.
