I have a VB.NET program that needs to programmatically use FTP to send files from one machine to another. WININET.DLL has functions which appear to be suited to this. I am having trouble getting it to work. On the call to function ConnectServer in the DLL, even though it returns non zero handle, the Err variable is non zero. Before posting some sample code, I would like to ask if anyone has done what I am trying, or is WININET.DLL only a VB6 product that is not usable on .NET. Thanks in advance.

Wininet.dll is not the VB6 file it is used by the OS and other application so that you can use the Wininet.dll under the .NET environment

Hi Rob!

I have used Wininet.dll for FTP files from one location to another and it never gave me any problem...Although I did it in VB6...but I can say with confidence that it should work with .NET too. When u set reference to the DLL in .NET, .NET creates an interop...so it should be able to call all the functions inside the DLL like FTPPut, FTPGet etc...We have used COM DLLs in our project and they work fine as they would in VB6...Just check whether u have set the reference properly and whether the Interop is made for the DLL in bin\debug directory...

cheers,

or you could re-write the wininet API Calls for FTP in .NET. I did them for one of my projects.
