All as I want to do is break when the value of Err.LastDLLError changes.
In VB6 I would just use a conditional watch with a global scope and I could see exactly the line that the change occurs but I don't see that ability in VB.net. Using conditional watches to see when a value changes was a great tool in VB6, I hope it's not something MS has taken away.
I do see that the breakpoints are very cool now but breakpoints are limited to the line they are on (as far as I know.)
I am using Visual Studio 2005.
