Windows Service Fails on Launch
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 conversi开发者_高级运维ons 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?

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.
Check your configuration file.
You might also check the account the service is running as. Just as a test go to the login tab in the services list and have it login under your own account. If the problem vanishes it's a permissions problem.
