help Printer papernames and papersizes

[TheCurrent 0]

AM trying to convert this code that retrieves printer papernames ans sizes from vb6 to autoit

Dim paperNumbers()      As Integer, paperSizes() As POINTAPI

lPaperCount = DeviceCapabilities(Printer.DeviceName, Printer.Port, DC_PAPERNAMES, ByVal vbNullString, 0)
    ReDim numPaper(1 To lPaperCount)
    sPaperNamesList = String(64 * lPaperCount, 0)
    ' Get paper names
    lPaperCount = DeviceCapabilities(Printer.DeviceName, Printer.Port, DC_PAPERNAMES, ByVal sPaperNamesList, 0)
    ' Get matching paper numbers
    ReDim paperNumbers(1 To lPaperCount)
    lPaperCount = DeviceCapabilities(Printer.DeviceName, Printer.Port, DC_PAPERS, paperNumbers(1), 0)
    ReDim paperSizes(1 To lPaperCount)
    lPaperCount = DeviceCapabilities(Printer.DeviceName, Printer.Port, DC_PAPERSIZE, paperSizes(1), 0)
    For lCounter = 1 To lPaperCount
        sNextString = Mid(sPaperNamesList, 64 * (lCounter - 1) + 1, 64)
        sNextString = Left(sNextString, InStr(1, sNextString, Chr(0)) - 1)
        List2.AddItem paperNumbers(lCounter) & vbTab _
            & Format(paperSizes(lCounter).x / 254, "0.00") & " x " _
            & Format(paperSizes(lCounter).y / 254, "0.00") _
            & " inch" & vbTab & sNextString
    Next lCounter

The auto it version

Dim $numPaper[$lPaperCount[0]]
 $lPaperCount = DllCall("winspool.drv", "long", "DeviceCapabilitiesA", "str", $objPrinter.Name, "str", $objPrinter.PortName, "int", $DC_PAPERSIZE, "str", DllStructGetPtr($paperSizes), "ptr", 0)
    
    Dim $OutPut
    For $lCounter = 1 To $lPaperCount-1
        $sNextString = StringMid($sPaperNamesList, 64 * ($lCounter - 1) + 1, 64)
        $sNextString = stringLeft($sNextString, StringInStr($sNextString, Chr(0),1,1,1) - 1)
        $OutPut &= $paperNumbers($lCounter) & @Tab 
        $OutPut &= StringFormat("%10.2f",$paperSizes($lCounter).x / 254) & " x "
        $OutPut &= StringFormat("%10.2f",$paperSizes($lCounter).y / 254)  & " inch" & @tab & $sNextString @CRLF
    Next

I don't het anything in my output.

$paperSizes is suppose to be and array of points (x,y) retrieved from the dllcall

If your printers are network printers managed by a spool server you can get a lot of information about the print queues using my AD UDF, function _AD_ListPrintQueues and _AD_GetObjectProperties.

I tried this, but it dosen't return the actual paper sizes. it returns series of 1s. the paper sizes is suppose to be Xmm x Ymm

#include <Array.au3>

$objWMIService = ObjGet("winmgmts:{impersonationLevel=impersonate}!\\.\root\cimv2")
$colInstalledPrinters = $objWMIService.ExecQuery ("Select * from Win32_Printer",Default,48)
For $objPrinter In $colInstalledPrinters
    $arr = $objPrinter.PaperSizesSupported 
    _ArrayDisplay($arr, $objPrinter.Name)
Next

help me get the names & sizes here, but am left with the papernumbers, please help me with the struct, thats where i get confused

in vb6 i can do this

Dim paperNumbers()  As Integer

and pass it to the api like this

' Get paper names
    lPaperCount = DeviceCapabilities(Printer.DeviceName, Printer.Port, DC_PAPERNAMES, ByVal sPaperNamesList, 0)
    ' Get matching paper numbers
    ReDim paperNumbers(1 To lPaperCount)
    lPaperCount = DeviceCapabilities(Printer.DeviceName, Printer.Port, DC_PAPERS, paperNumbers(1), 0)

in autoit i did this

but get the result posted at the buttom of that post

Yes, you need to translate the numbers yourself which is quite a simple job. Paper sizes is described on the page I linked you at: http://msdn.microsoft.com/en-us/library/aa394363(v=vs.85).aspx

For example I see my printer supports 8 which is A3. I know that it is 297x420 so I would make this code:

Switch $paperSizeType
   Case 8
      Return "A3 (297mm x 420mm)"
EndSwitch

The solution is not as good as the one MrMitchell gave you in the other thread, but when you say you "have been doing this for four days now by myself" doing this would mean that you were done 3 days ago.

what i meant by "have been doing this for four days now by myself" is that i have been trying to do it myself without success

By the way, how do i pass an array or int to dllcall and retrieve the result?

i tried this

$result = DllCall("winspool.drv", "long", "DeviceCapabilitiesA", "str", $objPrinter.Name, "str", $objPrinter.PortName, "int", $DC_PAPERNAMES, "str", Chr(0), "long", 0)
;Create all the structures to retrieve the necessary values
$NumberStruct = ""
For $i = 1 To $result[0]
$NumberStruct &="int;"
Next
$NumberStruct = StringTrimRight($NumberStruct, 1)
$pNumberStruct = DllStructCreate($NumberStruct)
;Get paper Numbers
$result1 = DllCall("winspool.drv", "long", "DeviceCapabilitiesA", "str", $objPrinter.Name, "str", $objPrinter.PortName, "int", $DC_PAPERS, "ptr", DllStructGetPtr($pNumberStruct), "long", 0)
For $i = 1 To $result[0]
ConsoleWrite(DllStructGetData($pNumberStruct, $i) & @CRLF)
Next

i got this
