Question : How to implement Exited eventhandler of System.Diagnostics.Process?

hi,

I have the below code to invoke a process and it works fine as long as there is no exception from P_Exited().

The method "StartUploadProcess" will return true or false. Even if there is an exception from P_Exited(), "StartUploadProcess" is always returning "true".
I need to make it return false if there is an exception from P_Exited().

Thanks for any help.
