Hey PMS , thanks for that prompt post...

That really worked fine......
However , on WIN NT machine it is returning empty Value....
I read that it picks up from win.ini File and since the mentioned
section and key name were absent in my win.ini file on WIN NT
machine it is displaying Emty String....

Would you be able to give me any further inputs on this , Pls ...

Also , I would need to find , if the Printer status is ready ....
would appreciate your help on this issue too , if I am not demanding too much......

Ok no probs.Try the below method.Hope this will solve.

char *GetPrinterName()
{
DWORD dwValues;
DWORD idw;
LONG lReturn;
HKEY hQKey = NULL;
TCHAR szStr[200];
DWORD dwValueNameLen,dwValueLength;
DWORD dwType;
BOOL Ok;

unsigned char *szValue=new unsigned char[255];
char *szErrorValue=new char[255];
strcpy(szErrorValue,"No printers");


lReturn = RegOpenKeyEx (HKEY_CURRENT_USER,"Printers",0L,KEY_ALL_ACCESS, &hQKey);
Ok = (lReturn == ERROR_SUCCESS);
if (Ok)
{

lReturn = RegQueryInfoKey( hQKey, NULL, NULL, NULL
, NULL, NULL, NULL, &dwValues, NULL, NULL, NULL, NULL );

Ok = (lReturn == ERROR_SUCCESS);
}
if(Ok)
{
for ( idw=0; ((idw<dwValues) && Ok); idw++) {
dwValueNameLen = 200;
dwValueLength=255;
lReturn = RegEnumValue(
hQKey
, idw
, szStr
, &dwValueNameLen
, NULL
, &dwType
, szValue
, &dwValueLength
);
if(strcmp(szStr,"DeviceOld")==0)
{
for(unsigned int index=0;index < strlen((char *)szValue);index++)
{
if(szValue[index]==',')
{
szValue[index]='\0';
break;
}
}
return (char *)szValue;
}
}
}

if (hQKey != NULL)
{
RegCloseKey (hQKey);
hQKey = NULL;
}
return szErrorValue;
}


You can get the status of the printer from PRINTER_INFO_2 and
JOB_INFO_2 structures.... Any further queries you can feel free to ask.
