Hello All,

I have a simple MFC app that takes in a URL for a CAB file and tries
to download all the files from the URL codebase.
It downloads the files specified( I have TRACE messages in the
OnProgress() call of the BindStatusCallback interface )completely. But
then it fails to register any of the OCX files contained within them.
In fact I changed the INF file so that it would now download to a
subdirectory under %system32% and I have included this whole path into
the %PATH% environment variable, no luck with that either.

THis is how I am calling the CoGetClassObjectFromURL():

               CString strMIMEType = "appication/x-cabinet-Win32-x86";

        hr = CoGetClassObjectFromURL(CLSID_NULL, T2OLE(strcodebase),
                                 0xFFFFFFFF, 0xFFFFFFFF,
                                                 T2OLE(strMIMEType), m_pBindContext,
                                 CLSCTX_INPROC_SERVER | CLSCTX_INPROC_HANDLER,
                                 0, IID_IClassFactory, (void **)&pClassFactory
                                );

Since the CLSID is being passed as NULL, it's doing an asynchronous
download.
I am passing NULL for the CLSID as I am downloading a CAB file. I am
guessing this is the right way.

Any inputs are greatly appreciated.

Thanks in advance.

BTW, strMimeType = "application/x-cabinet-Win32-x86" ( I missed an 'l'
in my original post )

This is the ouput that I am writing out from the OnProgress() call:
