It's as simple as that. I don't know what else you've got in place that is causing this linker error. If I omit the Sensapi.lib, I get an LNK2001 error.
I was unable to find LNK2019. Is this a .NET project?

Can you show me how (few lines) including how to create some LPQOCINFO ?
This is my source part that generate this error.
if ( IsDestinationReachable("www.google.com", NULL) == TRUE)
AfxMessageBox("Google ok !");

QOCINFO oci;
oci.dwSize = sizeof(QOCINFO);
IsDestinationReachable("www.google.com", &oci);

Still doesn't working...thank you for your effort, but please help me one more time .. I'm gona crazy wit this...
This is part of my code. As you may see that I include Sensapi.h, and in properties of application I include library SensAPI.Lib (/IMPLIB:"SensAPI.Lib").
Do you have any earthly Idea what might be wrong with this ?
#include "stdafx.h"
#include "MYPRG.h"
#include "MYPRGDlg.h"
#include "Sensapi.h"
#ifdef _DEBUG
#define new DEBUG_NEW
#endif
......
BOOL MYPRGApp::InitInstance()
{
...
QOCINFO oci;
oci.dwSize = sizeof(QOCINFO);
IsDestinationReachable("www.google.com", &oci);
....

So you have "sensapi.lib" in the Object/library modules: box on the Link tab of the Project Settings dialog?

So where is the /IMPLIB operative being used?

Sorry...misunderstanding
From options you may see that /IMPLIB:"Sensapi.lib" is there.
/OUT:"Debug/MYPRG.exe" /INCREMENTAL /NOLOGO /DEBUG /PDB:"Debug/MYPRG.pdb" /SUBSYSTEM:WINDOWS
/IMPLIB:"Sensapi.lib" /MACHINE:IX86
I also try to include Sensapi.DLL file in this .cpp source, but still get same error.
Do you think that I have to configure, or setup, or.... I don't know what else should I and where to...
Should I put #include "Sensapi.h" directive on some particula place, should I include this library somwhere else except this (MYPROG Property Pages --> Configuration Properties --> Linker --> Advanced --> Import Library --> Sensapi.lib) ?
I try to find some source code (or project file) that use this function on Internet, but it wasn't successfully.
Do you have any other idea what might be wrong ?

/IMPLIB is for telling the linker to generate an import library with that name, based on the exports from your binary.
To use an import library, you include it in the list of files to link. In the Visual Studio .NET IDE, this is found under Configuration Properties > Linker > Input > Additional Dependencies.
If you've already been using /IMPLIB, your output directory will likely contain a file sensapi.lib, which could cause the linker to pick that file. If so, delete it.

Thank you !!!!!!!!!!!!!!!!!!!!!!!
It's working !!!
I can't believe it !!!!
Thank you !!!

Interesting thing is that, if I omit the Sensapi.lib, I get the same error as I get it with included library ?!

According to the documentation[^], the import library for IsDestinationReachable is sensapi.lib.
Have you perhaps changed configurations (e.g. from Debug to Release) and only included that library in the Link tab for one of them?

I want to change the internet option by my program, but I don't know which file the option is saved in. I didn't find it in registry file.
Does anyone have any good idea to solve this problem? I'll appreciate anyone know it reply my question.

I want to change the option in Secruit->ActiveX control and Plug-ins

First place to look would be in HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings\SO\ACTIVE_CONTENT. After that, you might need to employ Internet Explorer automation.

I was ebla to open the file, but I have trouble getting data.
My file looks like this:
account amount pendamount
123456 231.00 78.00
I need to read the data into variable account and amount then use get() again with no argument in order to through away the new line character at the end of the line .
Thanks

Show us the code you are using.

char c;
while (inpf.get(c)) {
cout.put(c);
}
the second version:
inpf.seekg(ios::beg);
static char read_array[10]; inpf.read(read_array,15);
|
|
|
|
|
char c;
while (inpf.get(c)) {
cout.put(c);
}

Are you sure this is what you are using? Your original request was to "read the data into variable account and amount then use get() again with no argument in order to through away the new line character at the end of the line." What you have here is not even close. It simply reads and displays one character at a time of the file.
See if this is any closer:
string account, amount, pendamount;
while (...)
{
inpf.getline(account, 15, ' ');
inpf.getline(amount, 15, ' ');
inpf.getline(pendamount, 15, ' ');
}
