GetDefaultPrinterA' undeclared

[karang]

Hi

I am using this code to set the default Orientation of the printer
[Code]
int SetDefaultPrinterOrientation(short dmOrientation)
{
HANDLE hPrinter = NULL;
DWORD dwNeeded = 0;
PRINTER_INFO_2 *pi2 = NULL;
DEVMODE *pDevMode = NULL;
PRINTER_DEFAULTS pd;
BOOL bFlag;
LONG lFlag;
LPTSTR pPrinterName = NULL;
DWORD size;
GetDefaultPrinter(NULL, &size);
TCHAR* buffer = new TCHAR[size];

if(GetDefaultPrinter(buffer, &size))
pPrinterName = buffer;
else
{
if(buffer != NULL)
delete buffer;
return 0;
}

// Open printer handle (on Windows NT, you need full-access because you

// will eventually use SetPrinter)...

ZeroMemory(&pd, sizeof(pd));
pd.DesiredAccess = PRINTER_ALL_ACCESS;
bFlag = OpenPrinter(pPrinterName, &hPrinter, &pd);
if (!bFlag || (hPrinter == NULL))
{
if(buffer != NULL)
delete buffer;
return 0;
}
// The first GetPrinter tells you how big the buffer should be in

// order to hold all of PRINTER_INFO_2. Note that this should fail with

// ERROR_INSUFFICIENT_BUFFER. If GetPrinter fails for any other reason

// or dwNeeded isn't set for some reason, then there is a problem...

SetLastError(0);
bFlag = GetPrinter(hPrinter, 2, 0, 0, &dwNeeded);
if ((!bFlag) && (GetLastError() !=
ERROR_INSUFFICIENT_BUFFER) || (dwNeeded == 0))

[\code]

But while executing the code I am getting the compile time error

35 C:\C++ Examples\GeneralPrinterOperations.cpp `GetDefaultPrinterA' undeclared (first use this function)

But GetDefaultPrinter is windows API function

Why I am getting this error.

Kindly advice

That is a lot of code, and I would have difficulty going through it under normal circumstances.. but i'd be more willing to try if you would just do me a quick favor. Please edit the above post and put code tags around the code itself. Thanks.

If GetDefaultPrinter is a WindowsAPI function. Have you included the windows header file?
