Printer enumeration problem

Hello.
I have a problem with printer enumeration...The following code works ok on XP, but not on Win2k.
On Win2k network printers don't show up in the dropdown list, even though they are installed on the local machine. Printers that are physically connected to a port on the local machine, however, show up..!

Code:

---

if(EnumPrinters(PRINTER_ENUM_LOCAL|PRINTER_ENUM_CONNECTIONS, "", 5, (UCHAR*)pI1, sizeof(PRINTER_INFO_2)*MAX_PRINTERS, &lSize, &lRet)){
  for(int i=0;i<(int)lRet && i<MAX_PRINTERS;i++){
    SendMessage(GetDlgItem(hwThis, CBO_PRT), CB_ADDSTRING, 0, (long)pI1[i].pPrinterName);
    strcpy(achPorts[i], pI1[i].pPortName);
    if(!strcmp(pI1[i].pPrinterName, sil->achPrinter))
      chIx=i;
  }
}else
  GetErr("EnumPrinters");

Try add an extra flag to the first param...probably PRINTER_ENUM_NETWORK

I've tried all different flag versions.
The function call returns successfully, but does not return printers connected through the network...

Hmm...

Try this...I havent checked it on Win2000 but see if it works

Code:

---

#include <windows.h>
#include <iostream>

int main()
{
        DWORD Needed = 0,Found = 0;
        union PRINT_INFO_ENUM
        {
                PRINT_INFO_ENUM():AsBytes(0){}
                LPBYTE AsBytes;
        PRINTER_INFO_1 *AsInfo;
        }PrinterInfo;

        //Get size of array
        EnumPrinters( PRINTER_ENUM_LOCAL | PRINTER_ENUM_CONNECTIONS ,0,1,0,1,&Needed,&Found);
       
        try
        {
                PrinterInfo.AsBytes = new BYTE[Needed];
        }
        catch(...)
        {
                std::cout << "Memory Error";
                return -1;
        }
       
        //Enum
        if(!EnumPrinters(PRINTER_ENUM_LOCAL | PRINTER_ENUM_CONNECTIONS ,0,1,
                PrinterInfo.AsBytes,Needed,&Needed,&Found))
        {
                std::cout << "Unable to enumerate " << GetLastError();
                return -1;
        }

        for(DWORD i = 0;i < Found;++i)
                std::cout << PrinterInfo.AsInfo[i].pName << std::endl;

        delete [] PrinterInfo.AsBytes;
}

I use PRINTER_ENUM_FAVORITE

Now i have tried all of what you have suggested, with the same results...
The OS is win2k server, i wonder if this is the problem..?

I use a print info 2 on NT based OS and print info 5 on 9X.

EnumPrinters (PRINTER_ENUM_FAVORITE | PRINTER_ENUM_LOCAL, NULL, 2, (PBYTE) pinfo2, dwNeeded, &dwNeeded, &dwReturned) ;

I have also found the name returned in the Devinfo can be truncated. (if you are trying to match them exactly)

Still returns nothing...I'm fetching the printers directly from the registry instead.
Thank you for your time anyway... :)
