Can I help to convert the next C++/CLI code to Visual Studio 2002 Managed C++?

bool IsPrinterOk(String ^printerName)
{
bool bResult=false;
HANDLE hPrinter;

IntPtr pPrinterName=Marshal::StringToHGlobalUni(printerName);
WCHAR \*pChar=(WCHAR \*)pPrinterName.ToPointer();

if(::OpenPrinter(pChar,&hPrinter,NULL)==0)
    return false;

DWORD bytesNeeded;
::GetPrinter(hPrinter,2,0,0,&bytesNeeded);
PRINTER\_INFO\_2 \*pf=(PRINTER\_INFO\_2 \*)GlobalAlloc(GPTR,bytesNeeded);

if(::GetPrinter(hPrinter,2,(LPBYTE)pf,bytesNeeded,&bytesNeeded)!=0)
    if(pf->cJobs==0 && pf->Status==0)
        bResult=true;

GlobalFree(pf);

ClosePrinter(hPrinter);

return bResult;

}

What changes must be made in the code? Thanks.
