Dear Sir,
I have copied the code from MSDN in order to use IADsWinNTSystemInfo to get the machine name and PDC. The code is listed as follows.
#include <activeds.h>
#include <stdio.h>
int main()
{
HRESULT hr;
hr = CoInitialize(NULL);
IADsWinNTSystemInfo *pNtSys;
hr = CoCreateInstance(CLSID_WinNTSystemInfo,
NULL,
CLSCTX_INPROC_SERVER,
IID_IADsWinNTSystemInfo,
(void**) &pNtSys);
BSTR bstr;
hr = pNtSys->get_UserName(&bstr);
if (SUCCEEDED(hr)) {
printf("User: %S\n", bstr);
SysFreeString(bstr);
}
hr = pNtSys->get_ComputerName(&bstr);
if (SUCCEEDED(hr)) {
printf("Computer: %S\n", bstr);
SysFreeString(bstr);
}
hr = pNtSys->get_DomainName(&bstr);
if (SUCCEEDED(hr)) {
printf("Domain: %S\n", bstr);
SysFreeString(bstr);
}
hr = pNtSys->get_PDC(&bstr);
if (SUCCEEDED(hr)) {
printf("PDC: %S\n", bstr);
SysFreeString(bstr);
}
if(pNtSys) {
pNtSys->Release();
}
CoUninitialize();
return 0;
}
However, VC reported the following error when compiling

Thanks
Cannot compile the sample from MSDN IADsWinNTSystemInfo

You need to add the libraries for the Win32 APIs you're calling to the linker settings. To find out the names of libraries, search up the corresponding API in MSDN.
krv5, you should open a new thread if you need assistance. Unfortunately, changing to a static library does not solve the problem of compiling and linking an executable.

Sir,
Yes. I have installed Platform SDK.

Did you installed the Platform SDK

I am having a similar problem, but strangely, it goes away when I change the configuration type from Application to Static Library.
