Hello,

Can you help me with a CustomMarshaler?
I would be apreciated.

I need to create a CustomMarshaler for the type MPR_SERVER_HANDLE.

The function I’m using:

public static extern HandledEventArgs MprAdminServerConnect
(
[In][MarshalAs(UnmanagedType.LPWStr)] string lpwsServerName,
[Out][MarshalAs(UnmanagedType.CustomMarshaler)] string phMprServer
);

The CustomMarshaler is for the parameter phMprServer, and the type I need is MPR_SERVER_HANDLE.
I’m quite new to c#, thats why even with your examples i’m not able do it. Can you help me with this ?

Many thanks

Hi Aaron

Thanks for the post. I have a question and a comment.

Question: How do you make this work for a returned struct?

Comment: The link to part 1 of this post seems to be broken. I would love to see it.
