System.DirectoryServices

Having connected to a domain object, I want to read the minPwdAge and
maxPwdAge properties. These, however, are of type "Large Integer/Interval"
and there doesn't seem to be marsalling support for these. They come across
as System.__ComObject, and I can't do much with that.

Any ideas how I can get the data?

Something like:

public static long FromLargeInteger (DirectoryEntry Entry, string
LargeAttribName)
{
ActiveDs.LargeInteger Work = (ActiveDs.LargeInteger)
Entry.Properties[LargeAttribName].Value ;
return (((long) Work.HighPart) << 32) | (Work.LowPart & 0xFFFFFFFF) ;
}

Hi Trevor,

A good place to go look for answers for these kind of questions is the
System.DirectoryServices portal on MSDN:

http://msdn.microsoft.com/library/default.asp?url=/library/en-us/sds/sds/portal.asp

There's a Quick List for C# Code Examples under the "Using
System.DirectoryServices" node, which contains lots of code snippets
for common operations.

One of them is called "Large Integer Property Type" and gives you an
explanation and code sample as to how to access (read) and set (write)
a Large Integer property in AD.

Thanks. Works fine.

(I was close. Was fiddling with ActiveDS._LARGE_INTEGER.Quadpart but that
didn't get me there.)
