EnumJobs
The EnumJobs function initializes an array of either JOB_INFO_1 or JOB_INFO_2 structures with data describing the specified print jobs for the specified
printer.
BOOL EnumJobs(
HANDLE hPrinter,
| // handle to printer object
| DWORD FirstJob,
| // location of first job in print queue to enumerate
| DWORD NoJobs,
| // number of jobs to enumerate
| DWORD Level,
| // structure level
| LPBYTE pJob,
| // pointer to structure array
| DWORD cbBuf,
| // size of array, in bytes
| LPDWORD pcbNeeded,
| // addr. of variable with no. of bytes copied (or required)
| LPDWORD pcReturned
| // addr. of variable with no. of job info. structures copied
| );
|
|
Parameters
hPrinter
Handle to the printer object whose print jobs the function will enumerate.
FirstJob
Specifies the zero-based position within the print queue of the first print
job to enumerate. For example, a value of 0 specifies that enumeration should
begin at the first print job in the print queue; a value of 9 specifies that
enumeration should begin at the tenth print job in the print queue.
NoJobs
Specifies the total number of print jobs to enumerate.
Level
Specifies whether the function should use JOB_INFO_1 or JOB_INFO_2 structures to store data for the enumerated jobs. A value of 1 specifies that
the JOB_INFO_1 structure should be used; a value of 2 specifies that the JOB_INFO_2 structure should be used.
pJob
Points to an array of either JOB_INFO_1 or JOB_INFO_2 structures.
cbBuf
Specifies the size, in bytes, of the array pJob.
pcbNeeded
Points to a variable that receives the number of bytes copied if the function
succeeds. If the function fails, the variable receives the number of bytes
required.
pcReturned
Points to a variable that receives the number of JOB_INFO_1 or JOB_INFO_2 structures that were initialized.
Return Values
If the function succeeds, the return value is nonzero.
If the function fails, the return value is zero. To get extended error
information, call GetLastError.
Remarks
The handle hPrinter is obtained by calling the OpenPrinter function.
The JOB_INFO_1 structure contains general print-job information; the JOB_INFO_2 structure has much more detailed information.

Nostalgia .Net |
|
.Net is powerful, but not all-powerful, so sometimes we need to use Win32 API for our .Net applications. It's simple enough with Platform Invoke if you have Win32 skill, but we do not always have time to dig the ancient documentation, declare the special types that are compatible with Win32, find the values of the Win32's constants and so on. Nostalgia .Net offers several simple-to-use classes, and components that will allow you to forget about the headache of Win32 and just use the power of Win32 in your application the same way as you use the native. Net classes. More » |
