Failure to link to a DLL

[mlockwood]

I would be grateful if someone can help a poor Delphi programmer. I need to use a DLL provided by someone else to carry out a simple fire-and-forget action.
I have been provided with two files :
aiqsdkif.lib
aiqsdkif.dll

which I know contain the three routines I need namely :

InstallAIQ();
UninstallAIQ();
RebuildMasterTickerList();

There are two files that I have cloned fromthose provided to me :
AIQSDK.h :
---------------------------------------------------------------------
#ifndef __AIQSDK_H
#define __AIQSDK_H

#ifdef _WIN32
# ifndef _AIQSDK_
# define AIQSDKAPI __declspec( dllimport )
# else
# define AIQSDKAPI __declspec( dllexport )
# endif
#else
# define AIQSDKAPI
#endif

#ifdef __cplusplus
extern "C" {
#endif

AIQSDKAPI void FAR PASCAL InstallAIQ();
AIQSDKAPI void FAR PASCAL UninstallAIQ();
AIQSDKAPI BOOL FAR PASCAL RebuildMasterTickerList();

#ifdef __cplusplus
};
#endif

#endif //__AIQSDK_H
---------------------------------------------------------------------

SDKTest.cpp
---------------------------------------------------------------------
#include "windows.h"
#include <stdio.h>
#include <conio.h>
#include &quot;aiqsdk.h&quot;

int main(int argc, char* argv[])
{
InstallAIQ();
RebuildMasterTickerList();
UninstallAIQ();
return 0;

}

---------------------------------------------------------------------
The program compiles but fails to link with the messages :

Linking...
SDKtest.obj : error LNK2001: unresolved external symbol __imp__UninstallAIQ@0
SDKtest.obj : error LNK2001: unresolved external symbol __imp__RebuildMasterTickerList@0
SDKtest.obj : error LNK2001: unresolved external symbol __imp__InstallAIQ@0
Debug/Test1.exe : fatal error LNK1120: 3 unresolved externals

I guess there must be some way of linking in the .lib or dll files
But I am afraid I use Visual C++ (6) so little I do not know what to do.

put aiqsdkif.lib in Project->Settings->Link-> aditional libraries. Ion Filipski

add this line in stdafx:
#pragma comment(lib,aiqsdk);

Or you can add the line as the first line in your main .h or .cpp file.

Sorry, my mistake. Put the quotes like this. I hope this answer is still of some use.

#pragma comment( lib, &quot;aiqsdk&quot; );

where aiqsdk is the name of your .lib file.
