I'm new to both InfoPath and C#. I've used the following URL as a primer to
get going:

http://msdn.microsoft.com/office/default.aspx?pull=/library/en-us/odc_ip2003_tr/
html/odc_INF_Lab_15.asp

What I'm trying to do is retrieve the current username which in my
environment would look like "doejo" for the name "John Doe". It's the
lastname plus the first two characters of the users firstname. I then need to
match that username in Active directory by searching the field
"SAMAccountName" which would match the current username (doejo).

The code comppiles correctly but when the InfoPath form is published nothing
happens at startup.

What am I missing?

What' the value of your "strUserName" ? I think you have a null string.
I've got the same problem when i launch my form by Sharepoint. I always
return a null string.I don't understand why.

Hello,

instead of Environment.Username, try
System.Security.Principal.WindowsIdentity.GetCurrent().Name
