C# DLL's

[xarzu]

I thought that my problem was how I was declaring a manifest file.
But now I think I can safely rule this out.

I think the probem lies in the way I am loading the DLL/COM object
that the manifest file references.

The program runs -- sort of. After I embed the manifest file into
the executable. I just cannot step through the code in debug mode.

So I put the manifest file into the list of files that the IDE had
to reference. And then I noticed a big change. Then the executable
that I produced had an error message (that I could ignore and continue
running the program, if I choose to) that said the probem was
with the way I was loading the COM object.

How do I load a DLL into a GUI front-end written in C#. Where
should I look for possible problems?

Add it as a reference. It should appear in your list once you do.

Add it as a reference. It should appear in your list once you do.

I have added it as a reference. It still has a problem running a method declared in the DLL.

Maybe there is a problem with the way I am using the DLL. How do I simply add a DLL to a project and expose its methods? All I am doing is this so far. I have added the DLL to the Solutions Explorer as a Reference. Then, in the C Sharp file where I make the function call, I list the DLL at the top of the file as one of the "using" types. That seems to be all that is done in the code. What more do I need?

Is the DLL for unmanaged code, you will have to set up the links for the function calls manually

[DllImport("wpcap.dll", CharSet=CharSet.Ansi)]
internal extern static int pcap_compile (IntPtr /* pcap_t* */ adaptHandle, IntPtr /*bpf_program **/fp, string /*char * */str, int optimize, UInt32 netmask);
