Creating TCP/IP Port programatically

[sairam.madem]

Hi, I am trying to create a TCP/IP port programatically in win32.

Here is my code.


HANDLE hXcv;PRINTER_DEFAULTS pd = {NULL, NULL, SERVER_ACCESS_ADMINISTER};TCHAR szBuf[MAX_PATH] ={0};TCHAR szMsg[512];DWORD dwLastError;::lstrcpy(szBuf, TEXT(",XcvMonitor Standard TCP/IP Port"));if(OpenPrinter(szBuf, &hXcv, &pd) != FALSE ){ OutputDebugString(TEXT("Hello. It worked....!"));}else{ dwLastError = GetLastError(); wsprintf(szMsg, TEXT("OpenPrinter return error:%d\n"), dwLastError); OutputDebugString(szMsg);}> But the problem is OpenPrinter API failing and returning
error code as 5 (ERROR_ACCESS_DENIED).

> But when I try to create the port manually (print properties), port is created.
> I have logged in as an administrator and I have all permissions.

I am working on Windows Server 2008 R2 Statndard (64 bit OS)

Note: OpenPrinter API working fine if I turn-OFF User Account Settings (UAC). Failing if UAC is ON

Please tell me what's wrong with my code.

Thank you in advance.

I have no idea what that code says but try right clicking your app and selecting 'Run as Administrator'.

Hi this is the code....


HANDLE hXcv;

PRINTER_DEFAULTS pd = {NULL, NULL, SERVER_ACCESS_ADMINISTER};

TCHAR szBuf[MAX_PATH] ={0};

TCHAR szMsg[512];

DWORD dwLastError;

::lstrcpy(szBuf, TEXT(",XcvMonitor Standard TCP/IP Port"));

if(OpenPrinter(szBuf, &hXcv, &pd) != FALSE )
{
OutputDebugString(TEXT("Hello. It worked....!"));
}
else
{
dwLastError = GetLastError();
wsprintf(szMsg, TEXT("OpenPrinter return error:%d\n"), dwLastError);
OutputDebugString(szMsg);
}

According to MSDN article OpenPrinter Function:

If a user does not have permission to open a specified printer or print server with the desired access, the OpenPrinter call will fail with a return value of zero and GetLastError will return the value ERROR_ACCESS_DENIED.
