I work with visual studio 2012 I mean visual basic

Okay, I am asking again: what exactly do you mean by "VB", or "Visual Basic"? However, 2012 tells me that this is VB.NET. Do you know the difference? :-)

Solution 1 explains you: you can use P/Invoke. Also, you can use mixed/mode (managed+unmanaged C++/CLI + native C++) assembly to wrap native code from that DLL and expose as managed CLI ("ref") classes. Which way would be more convenient for you?

Solution 1

WinFax.DLL cannot be added as a reference because it is not a .NET executable, so it does not contain .NET assemblies or code.

You could use it via P/Invoke, but it might be easier for you to use Google to find a .NET fax solution instead - I know they exist, but I've never used any, so I can't recommend one to you.

You mean that I can not use winfax.dll in my project?but I need it for receiving fax in vb application?

OriginalGriff 5-Jan-14 5:08am

You can ... probably (I haven't tried because noone I know uses fax any more), but it won't be simple: It's not .NET code it's native so it doesn't integrate well. You can use it if you google for "VB P/Invoke C++" but it will probably require a fair amount of work on your part.
It would probably be simpler to find a .NET compatible fax solution.
