Add Library to Visual Studio 2008 C++ Project

Question

I'm completely new to Visual Studio and I'm having some trouble getting a project started with Visual Studio 2008. I'm experimenting with MAPI, and I'm getting error messages like this when I go to build the project:

"unresolved external symbol _MAPIUninitialize@0 referenced in function _main"

I know I need to link to MAPI32.lib, but the guides I have found thus far have indicated going to the "Visual Studio settings link tab" and adding it there (which was - apparently - from an older version of Visual Studio). I can't find anything like that in the project properties linker or C/C++ sections of VS 2008.

Where do I need to tell Visual Studio to use that library?

Thanks

Answer 1

It's under Project Properties / Configuration Properties / Linker / Input / Additional Dependencies.

The help tip at the bottom of the screen says "Specifies additional items add to the line line (ex: kernel32.lib)".

Answer 2

Project Properties->Linker->Input->Additional Dependencies

You can also use #pragma comment( lib, "mapi32" ) in one of your source files. As noted MSDN here is a similar library addition using the pragma technique MSDN - Creating a Basic Winsock Application

#include <winsock2.h>
#include <ws2tcpip.h>
#include <stdio.h>

#pragma comment(lib, "Ws2_32.lib")

int main() {
  return 0;
}

Three simple steps:

1. Project Properties->Linker->General->Additional Library Directories choose the folder which contains your .lib file

2.Project Properties->Linker->Input->Additional Dependencies Just enter the name of your .lib files

3.Project Properties->C/C++->General->Additional Include Directories choose the folder where your .h files locate

It is also possible to just drag'n'drop library file to project in Solution Explorer.

Do not statically link to any MAPI dlls. You must always dynamically load the MAPI system - look at the MFCMAPI source code to see how it is done: http://mfcmapi.codeplex.com/
