Urgent: C# version of WinInet API

Hi, Can anybody please provide me with the C# versions of the wininet api functions for Compact framework like "InternetAutodial" etc. I am very much confused with the data types given in the original function definitions. For example, when i try to use the function: HINTERNET WINAPI InternetOpen( LPCTSTR lpszAgent, DWORD dwAccessType, LPCTSTR lpszProxy, LPCTSTR lpszProxyBypass, DWORD dwFlags ); I am confused about how to declare this function in C# and also how to call them. Or is there any other way to use these functions directly from C#. This is very urgent and hope I get an early reply. thanks very much in advance and regards mrc
