I write some very rudimentary data collection using VB 6.0. I use ibrd ibwrt and ibclr. I am wanting to move to VB .Net but I can't figure out how to make the dll calls. Many people have mentioned it but I can't figure it out. Also, I don't want to spend $500 + for the Measurement Studio when I don't need all the extra stuff. Could someone please post some code on how to do an ibrd and ibwrt in VB .Net?
