>BTW, what is in oProcess. at the moment of the error? Could you have wrong data (not string format)?

The line was cut. It should have been oProcess.oApp.cCr. This is a carriage return which is added after each line I add in my string builder in regards to that particular section. So, I have dozen of lines before that one and they all have the same oProcess.oApp.cCr at the end. I also tried to remove it. It didn't help.
