COM

your problem is that MIDL doesn't support the BOOL data type. In your .idl or .odl file (depending on what you're using) change the BOOL to boolean and then in the actual class implementation change it from BOOL to unsigned char. Try to find a table somewhere of data type mapping from MIDL to C++. O'Reilly's DCOM book has good examples of this. Hope this helps.

Hi If you have the fully qualified PIDL to that folder you can use the BindToObject method. Use Desktop IShellFolder interface to do this (get it with SHGetDesktopFolder).

Hi Liam Use SHGetDataFromIDList instead, and specify SHGDFIL_DESCRIPTIONID in nFormat parameter. Network items are SHDID_NET_*.

Hi, You have an option of passing all the parameters as SafeArray of bytes or you can use the wrapper COM object for the parameters. The second approach is much easier to use but it cost time to create/destroy extra object. As for me if I don't call the function too often I prefer to use a special object for passing parameters. There is an article in MSDN "OLE Q&A" by Don BOX which has more details on the topic... Regards, Alex Gorev, Dundas Software.

First of all Thanks for your help. I have found at MSDN site that for MFC application it is necessary to declare a callback function as a static, so I did and now it works fine. Dimitri.

Yap, let's write snapins using visual basic. C001!

1. It is needed in Interface to add DECLARE_CLASSFACTORY_SINGLETON(). 2. Instead of mount you may to register server on the client-machine in the manner: \\server-computer-name\drive\server.exe - regserver It is not good also, but you must not make mount.
