Linker Error using NetMon API in Visual Studio 2013

Question

I have problems compiling/linking the NetmonAPI in VS 2013. The API comes with installing MS Networkmonitor. Networkmonitor even has a explanation in the help how you can get it to work in VS. I followed the instructions how to set it up, tried an example from the help and failed. I always get the "LNK2019" Error for seven symbols.

The example code i'm using:

#include "Stdafx.h"
#include "windows.h"
#include "stdio.h"
#include "stdlib.h"
#include "objbase.h"
#include "ntddndis.h"
#include "NMApi.h"

void __stdcall 
MyFrameIndication(HANDLE hCapEng, ULONG ulAdaptIdx, PVOID pContext, HANDLE hRawFrame)
{
    HANDLE capFile = (HANDLE)pContext;
    NmAddFrame(capFile, hRawFrame);
}

int __cdecl wmain(int argc, WCHAR* argv[])
{
    ULONG ret;
    ULONG adapterIndex = 0;

    if(2 == argc)
        adapterIndex = _wtol(argv[1]);

    // Open a capture file for saving frames.
    HANDLE myCapFile;
    ULONG CapSize;
    ret = NmCreateCaptureFile(L"20sec.cap", 20000000, NmCaptureFileWrapAround, &myCapFile, &CapSize);
    if(ret != ERROR_SUCCESS)
    {
        wprintf(L"Error opening capture file, 0x%X\n", ret);
        return ret;
    }

    // Open the capture engine.
    HANDLE myCaptureEngine;
    ret = NmOpenCaptureEngine(&myCaptureEngine);
    if(ret != ERROR_SUCCESS)
    {
        wprintf(L"Error opening capture engine, 0x%X\n", ret);
        NmCloseHandle(myCapFile);
        return ret;
    }

    //Configure the adapter.
    ret = NmConfigAdapter(myCaptureEngine, adapterIndex, MyFrameIndication, myCapFile);
    if(ret != ERROR_SUCCESS)
    {
        wprintf(L"Error configuration adapter, 0x%X\n", ret);
        NmCloseHandle(myCaptureEngine);
        NmCloseHandle(myCapFile);
        return ret;
    }

    //Start capturing frames.
    wprintf(L"Capturing for 20 seconds\n");
    NmStartCapture(myCaptureEngine, adapterIndex, NmLocalOnly);

    Sleep(20000);

    wprintf(L"Stopping capture\n");
    NmStopCapture(myCaptureEngine, adapterIndex);

    NmCloseHandle(myCaptureEngine);
    NmCloseHandle(myCapFile);

    return 0;
}

One of the errors i get:

error LNK2019: unresolved external symbol "_NmCloseHandle@4" in Funktion "_wmain".

Here my steps:

Installation of the Windows Driver Kit (WDK)
I set up a new Console-Project in VS 2013
Adding following directorys in the project-properties under VC++- Directorys --> Include-Dir: "C:\Program Files\Microsoft Network Monitor 3\API", "C:\WinDDK\7600.16385.1\inc\api", "C:\WinDDK\7600.16385.1\inc\ddk"
Adding following directorys in the project-properties under VC++- Directorys --> Library-Dir: "C:\Program Files\Microsoft Network Monitor 3\API"
Adding "nmapi.lib" to Linker-->Input-->Additional Dependencies

I dont know if i maybe have a compability problem, cause the instructions are for VS 2005 and 2008..

Thanks in advance!

It's not able to find or link to the nmapi.lib library. Try adding this line to the top of the file, just as a test to determine if it makes any difference: "#pragma comment(lib, "nmapi.lib")" without the quotes. Then make sure you also set the "Library Include Directories" to the path where the lib is stored. HTH. — kvr, Feb 29 '16 at 17:30
I added the line and get the same failure... I'm getting now 108 additional failures like syntax-failures in "stdio.h". But when i copy the required headers from the WDK to my project, i'm just getting the 7 old failures again. There is also a "NMAPI.ddl" in the installation directory of NetworkMonitor. Do i have to copy it to a certain directory? — kyi, Mar 01 '16 at 06:24

I think it's a 32/64 bit problem.

In my case, I have a desktop machine with windows 7 64 bit OS.

I have a eclipse with windows sdk 7 toolchain.

I've got the same errors with yours but different environment.

I also have the 64 bit Microsoft Network Monitor 3.4 install.

It is a 64 bit one as you see.

Well, I have successfully compiled my test program with '/machine:x64' as a linker option.

This problem could be a 64-bit monitor library without 32-bit support.

So, I think you need one more linker option same with me.

Here is my compilation log with a windows sdk 7.

x64 env + linker option

x86 env + linker option

x86 env + no linker option

Refer to the microsoft site here.

Too late answer, maybe..
