Question

I’m trying to write a windows service. It installs fine, but fails when I run it with the following exception. I’ve searched for the string “MyNewProgramService”, but I can’t find any conversions that would throw this error. I’ve also added try/catch blocks to a bunch of code with custom exception handling without finding where this exception is occuring. I’m thinking it’s somewhere in the auto-generated configuartion/setup code. Any ideas?

Answer 1

it falls in method MyNewProgramService.OnStart, there Conversions.ToInteger is called somewhere. Just search for it in method. Then check parameter. It might come from config or something, thats why you don’t see string in text.
