[RESOLVED] print que

[RonR]

how can I display the "print que" ??

[jmcilhinney]

I don't claim to know how but I'm fairly sure it would involve unmanaged code. There may be a Windows API function or two, or maybe you could use WMI.

Edit: Just had a quick look at the API Guide and there's an EnumJobs function in the Windows API. That would be worth a look.

By the way, it's "queue", not "que".

I have seen "q" spelled 3-4 different ways.

There is an API call "EnumJobs" that lists the jobs in a given print queue:

    ' JobInfoLevels - The level (JOB_LEVEL_n) structure to read from the spooler
    Public Enum JobInfoLevels
        ' JobInfoLevel1 - Read a JOB_INFO_1 structure
        JobInfoLevel1 = &H1
        ' JobInfoLevel2 - Read a JOB_INFO_2 structure
        JobInfoLevel2 = &H2
        ' JobInfoLevel3 - Read a JOB_INFO_3 structure
        JobInfoLevel3 = &H3
    End Enum

    <DllImport("winspool.drv", EntryPoint:="EnumJobs", _
 SetLastError:=True, CharSet:=CharSet.Ansi, _
 ExactSpelling:=False, _
 CallingConvention:=CallingConvention.StdCall)> _
Public Function EnumJobs _
                (<InAttribute()> ByVal hPrinter As IntPtr, _
                 <InAttribute()> ByVal FirstJob As Int32, _
                 <InAttribute()> ByVal NumberOfJobs As Int32, _
 <InAttribute(), MarshalAs(UnmanagedType.U4)> ByVal Level As JobInfoLevels, _
 <OutAttribute()> ByVal pbOut As IntPtr, _
 <InAttribute()> ByVal cbIn As Int32, _
 <OutAttribute()> ByRef pcbNeeded As Int32, _
 <OutAttribute()> ByRef pcReturned As Int32 _
  ) As Boolean


    End Function

The source code for the printer usage monitoring application uses this and the related API calls - I'd suggest you download that as a reference...

ok and thanks!!!

There is also the QueryInformationJobObject for getting details that you may need to also display about print jobs in the "Q"

Then you've seen it spelled wrongly 2-3 different ways. The word is "queue".
