Hi,

I'm having trouble calling the function CryptRetrieveObjectByUrl (found in
Wincrypt.h). I posted to this forum earlier and I got an answer which I now
have tried without success.

The declaration looks like this:
[DllImport("cryptnet.dll", SetLastError=true)]
protected static extern bool CryptRetrieveObjectByUrl(

[MarshalAs(UmanagedType.LPStr)] string pszUrl,
                                                    IntPtr pszObjectOid,
                                                    uint dwRetrievalFlags,
                                                    uint dwTimeout,
                                                    out IntPtr ppvObject,
                                                    IntPtr hAsyncRetrieve,
                                                    IntPtr pCredentials,
                                                    IntPtr pvVerify,
                                                    IntPtr pAuxInfo);

As I stated in my earlier post it?s the second and fifth parameter which I?m
unsure of. However when I call the function it fails immediately and
Marshal.GetLastWin32Error() returns the value 2 ( = "The system cannot find
the file specified"). I've checked and cryptnet.dll is located in my
System32-folder (The call succeeds if I make the call via a c++-dll)

Any suggestions? Thanks in advance.
