Everybody is good, ask a technical question
I use WinDDK inside bitmap source compiled a printer driver, how to get to the current name of the print job?

CodePudding user response:

After the OpenPrinter EnumJobs or GetJob
Refer to the MSDN examples

 
BOOL ListJobsForPrinter (LPTSTR szPrinterName) 
{
HANDLE hPrinter; 
DWORD dwNeeded dwReturned, I; 
JOB_INFO_1 * pJobInfo; 

//You need a printer handle and open the printer 
if( ! OpenPrinter (szPrinterName, & amp; HPrinter, NULL)) 
Return FALSE; 

//First you call EnumJobs () to find out how much memory you need 
if( ! EnumJobs (hPrinter, 0, 0 XFFFFFFFF, 1, NULL, 0, & amp; DwNeeded, 
& DwReturned)) 
{
//It should have failed, but if It failed for any reason other 
//than "not enough memory", you should bail out 
If (GetLastError ()!=ERROR_INSUFFICIENT_BUFFER) 
{
ClosePrinter (hPrinter); 
Return FALSE; 
} 
} 
//the Allocate enough memory for the JOB_INFO_1 structures plus 
//the extra data - dwNeeded from the previous call tells you 
//the total size men 
If ((pJobInfo=(JOB_INFO_1 *) malloc (dwNeeded))==NULL) 
{
ClosePrinter (hPrinter); 
Return FALSE; 
} 
//Call EnumJobs (again) and let it fill out our structures 
if( ! EnumJobs (hPrinter, 0, 0 XFFFFFFFF, 1, (LPBYTE) pJobInfo, 
DwNeeded, & amp; DwNeeded, & amp; DwReturned)) 
{
ClosePrinter (hPrinter); 
Free (pJobInfo); 
Return FALSE; 
} 
//You 'r e done with the printer handle, close it 
ClosePrinter (hPrinter); 

//dwReturned tells how many jobs there are 
//Here, you 'l l simple display the number of jobs found 
Printf (" % d jobs \ n ", dwReturned); 
//It 's easy to loop through the jobs and access each one 
for(i=0; i{
//pJobInfo [I] is a JOB_INFO_1 struct for that job 
//so here you could do whatever you want for each job 
Printf (" % [d]] [% s \ n ", pJobInfo [I] JobId, pJobInfo [I] pDocument); 
} 

//Clean up 
Free (pJobInfo); 
Return TRUE; 
}
