fVisualBasic Application I RS

I am learning to use Visual Basic to write some RS applications and I am quite a new bee. I have gone through the course material. but there are only few simple eksamples for eksemple "how to open and close a griper" and " how to make object reappear in the same place after robot have picked it up in the pickup position". is there any one knows where I can find more VB eksemples for RS application?image
