Debugging Windows Service — ReVisit (Windows 7)

Question

Hi there have been lot of discussion on this topic(Debugging Windiows service) Earlier as well https://stackoverflow.com/search?q=debug+windows+service

But am having few problems implementing the same.

• I Tried adding attach process from VS 2008 but the particular .Exe is disabled so am not able to attach

• Also Tried the below code using debugger

   #if DEBUG Debugger.Launch(); #endif 

Am getting Error when debugger is called "UnHandled Exception Occured--JIT compiler was launched without any security permissions.To debug run as administrator"

I have Admin rights for this PC and am using Windows 7 how can i debug it ?

PS: I can debug making this an Console application. But want to know why the above method fails..Is there a way i can debug as a service ?

Answer 1

Possibly- start the JIT with proper privileges. ie start the service as administrator. You can set username and password for the service to use when starting.

Answer 2

When you attach the process the process should be running. These are the two ways I've used to debug services

1) Add a sleep timer in the beginning of your windows service, run the service, then in vs- Debug->attach to a process

2) Creating and Reading DUMP files (google DebugDiag [v1.2 is the newest?]) It can allow you to look for crashes in threads, memory leaks, cpu usage fluxs. Use WinDbg to read the dump files.
