if (string = null) //Doesn't this assign null to string?
if (string == null) //This is what you want, to check if string is null

I used the code as follows as it worked.
Note, c# is case-sensitive
if (child == null)
{
strError = "Some Error";
return false;
}

Yup, still trying to juggle Delphi and C# ) Would you believe, I used to

Delphi programs and I'm slowly migrating to C#.
