Re: problem in updating custom field on publishing event of Projec   

Several things:

1.       You need to use the SSP address in Impersonated applications, 
not the PSI Proxy.

a.       For example, this means that you should be setting 
ws_Project.Url to http://ruh-003-cr-001:56737/<SSPName>/PSI/Project.asmx 
<http://ruh-003-cr-001:56737/%3cSSPName%3e/PSI/Project.asmx> , where 
<SSPName> is the name of the SSP where your PWA site resides (e.g. 
SharedServices1).

2.       Why you are converting all your Guids to byte[]s before you 
store then in Guid variables? This is unnecessary. Guid() has a 
constructor that will take an existing Guid.

3.       Why have you derived LoginWindows in here? You cannot 
impersonate using LoginWindows. Futhermore, since ContextInfo contains 
all the information for the already authenticated user, such an exercise 
would be pointless anyway.

4.       Final point (and this may be where the exception is coming 
from) is that you're causing an infinite recursion through your use of 
the CheckIn event. You have a CheckIn event handler, which updates a 
project and checks it in, an act which will fire the CheckIn event, 
which will call your CheckIn event handler, which updates a project... 
ad infinitum. You need to have some sort of test in your code to cancel 
execution somehow (e.g. by throwing an exception) so that your code does 
not infinitely loop. This mistake is very common in event handlers, and 
is something that you really, really need to be careful of. Exceptions, 
in addition to being the proper way to handle errors, are useful when 
writing custom event handlers because they will automatically cancel the 
event handler.



HTH!
