Error LNK2001: unresolved external symbol "__declspec(dllimport) public: class CString __thiscall

Hi, I am trying to use 3rd party API interface in VC++ module. Below is all that I got in the package.

 < xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />

CdCore.dll

CdCore.lib

CdCored.dll

CdCored.lib

CdDefs.h

CdSdk.h

 

This is my program

 

#include <cstdio>

#include <conio.h>

#include <sys\types.h>

#include <string>                                 

#include <iostream>                            

 

#include <AFXWIN.H>

#include "cdsdk.h"  // Standard CDSDK header file

 

 

using std::cout;                         

 

 

CWinApp theApp;     // Keep MFC library happy (console app)

 

/* Submit a process file, wait for completion and then */

/* display the statistic records for the prccess       */

int  main(int argc, char *argv[], char *envp[])

{

            // Make sure that MFC has a valid resource handle (console app)

            AfxSetResourceHandle(::GetModuleHandle(NULL));

 

            try

            {

                        // Connect to the node and issue the 'SELECT PROCESS' command

                        CDNode node("MYNODE", "MYUSER", "MYPASSWORD");

                        CDProcIterator it = node.SelectProc();

                        while (it.HasMore())

                        {

                                    CDProcess proc = it.GetNext();

    I have set my General->Microsoft Foundataion Classes option to "use shared dll" and also set use of runtime libary to multithreaded dll. I still get this error. Please help.

  • Ozbravo

    But this error has nothing to do with the previous ones.
    Simply this function is not implemented in any of the modules!
    Did you added all lib's to the linker options

  • tphsu

    I do have cdcore.lib added to linker object/modules option.

    Thanks



  • Kerdany

    Sorry than you have to ask the creator of the lib files were you have to find
    CDMsgException::GetMsg(int)const
    if its a class that is implemented by the lib creator.

    Read the docs may be this is a function you have to implement!

  • peter gardiner

    Set the MFC usage to "Shared DLL"!
