Why EnumPrinter can't enum all printers in my "Printers and Fax" in WinXP?

[Hiu Sing Ngai]

Hello,
I've got a local printer attached in LTP1 and another shared printer
attached in another computer in the same workgroup. I've added that network
printer in my "Printers and Fax". However, I've tried to enum all printers
but can't enum that network printer but only the local printer. I use the
function like this:

DWORD dwNeeded = 0;
DWORD dwReturned = 0;
EnumPrinters(PRINTER_ENUM_LOCAL, NULL, 5, NULL, 0, &dwNeeded,
&dwReturned);
if (dwNeeded) {
LPPRINTER_INFO_5 ppi = (LPPRINTER_INFO_5)malloc(dwNeeded);
EnumPrinters(PRINTER_ENUM_LOCAL, NULL, 5, (LPBYTE)ppi, dwNeeded,
&dwNeeded, &dwReturned);
free(dwNeeded);
}

dwReturn = 1
I've also tried different PRINTER_ENUM_XXX flags but still same. Enum
network even return no printer at all.

Do you have any idea?

Thanks,

That whole printer stuff is a bit tricky... no, It's helluva
tricky. PRINTER_ENUM_CONNECTIONS is your friend, but I'm not
sure that it works with level 5. Here's a snippet of my code
which works correctly (I think so):

VERSIONINFO VI;
LPBYTE pPIBuffer;
PRINTER_INFO_4* lpPI4;
PRINTER_INFO_5* lpPI5;
...
GetVersionEx(&VI);
if (VI%dwPlatformId == VER_PLATFORM_WIN32_NT)
{
iFlags = PRINTER_ENUM_CONNECTIONS | PRINTER_ENUM_LOCAL;
iLevel = 4;
iSize = sizeof(PRINTER_INFO_4);
}
else
{
iFlags = PRINTER_ENUM_LOCAL;
iLevel = 5;
iSize = sizeof(PRINTER_INFO_5);
}
nB = 0;
nPrinters = 0;
EnumPrinters(iFlags, NULL, iLevel, NULL, 0, &nB, &nPrinters);

pPIBuffer = new char[nB];
lpPI4 = (PRINTER_INFO_4*)pPIBuffer;
lpPI5 = (PRINTER_INFO_5*)pPIBuffer;

if (EnumPrinters(iFlags, NULL_CHAR, iLevel, pPIBuffer, nB, &nB, &nPrinters)
...

Hello Jugoslav,
Thank you so much! PRINTER_ENUM_CONNECTIONS is what I want and works
for me.
