I was trying to use win API

as below but I am getting error. Can someone help me.

#include
#include
#include
typedef enum {
NameUnknown,
NameFullyQualifiedDN,
NameSamCompatible,
NameDisplay,
NameUniqueId,
NameCanonical,
NameUserPrincipal,
NameCanonicalEx,
NameServicePrincipal,
NameDnsDomain,
NameGivenName,
NameSurname
} EXTENDED_NAME_FORMAT, *PEXTENDED_NAME_FORMAT;

int main()
{
EXTENDED_NAME_FORMAT enf = NameFullyQualifiedDN;
LPWSTR pwszComputerName;
DWORD dwLen;

    dwLen = 0;
    GetComputerObjectNameW(enf, NULL, &dwLen);

    pwszComputerName = new WCHAR\[dwLen + 1\];
    if(NULL == pwszComputerName)
    {
        return 0;
    }
    if(!GetComputerObjectNameW(NameSamCompatible, pwszComputerName, &dwLen))
    {
        delete pwszComputerName;
        return 0;
    }

    sbstrTrustee = pwszComputerName;
    wprintf(L"GetComputerObjectName: %s\\n", pwszComputerName);
    delete pwszComputerName;

}

Some of Error message is as below.

Why do you redefine the EXTENDED_NAME_FORMAT enumeration? :confused:

I first try without defining enum after that try with enum. In both case I am getting compilation error.

Good morning, You are including the wrong header. Remove secext.h and add:

#include

The error message is telling you that it doesn't know the definition of SEC_ENTRY.

Victor Nijegorodov

Add these definition: #define _WIN32_WINNT 0x0500 #define SECURITY_WIN32 Remove the redefinition of enum. Define the sbstrTrustee variable. // edited: also don't forget to include the Secur32.lib library.

Hi Victor, I have modified program according to your suggestion but I am not getting expected result. I want to use NameFullyQualifiedDN enum value and get the fully qualified distinguished name (for example, CN=Jeff Smith,OU=Users,DC=Engineering,DC=Microsoft,DC=Com). Regards, Rajnesh

Sorry, I don't know what is wrong/correct in your test. I've just tested your code and got the result in the form: [my_domain_name].[my_computer_name]$ wich is in my case 100% correct.

Hi Victor, There was configuration issue with my windows laptop, so I was facing issue. Thanks for your feedback.
