I am working on the application (Compact Framework 2.0, Windows CE 5.0) that needs to access file share. I came across this post on this web site:

Now, the problem I am encountering with this is that the call to Marshal2.StringToHGlobalUni() ends up appending the letter B to the network resource string.

Is this a bug? How can it be avoided?

Thanks! 

What version of the Smart Device Framework is your project referencing? 

version 2, community edition

 any thoughts?
 

I have bypassed a problem when I was getting random letters appended by  StringToHGlobalUni by appending "\0" to the parameters passed. Mapping works!!!!

Now, the only question I have left is how do I pass the domain to the network login?

After trying out this example, I still get the network logon prompt. (Which is what I am trying to get rid of by mapping programmatically).

You're probably going to have to convert this mess to managed code.  It's been on my "list of things to do" for a long time, but obviously hasn't happend so far (and no idea when I might actually get around to it). 

As for the initial problem, I looked at the code and it appears we make the assumption that Marshal.AllocHGlobal initializes its memory after allocation, but the behavior you're seeing suggests otherwise (the extra character was garbage in memory that simply didn't get cleared).  I've updated the SDF source so if you have purchased the Extensions you can send an email to support@opennetcf.com and request the code patch (it's really simple). 

^^ Yes, I saw this link. Someone has referred me to it on the MSDN forums (you are popular):)

A co-worker has recently come across this: (Credential Manager class)

I haven't tried these yet, but everyone I talk to, refers me to your C code. Have you had any exposure to this class (Credentials Manager) ?
