Printing using Martin's UDF & DLL; _PrintSetPrinter()

[MikahS]

I am just starting to use this UDF and I'm not sure if it's my sheer ignorance with this UDF or something that's missing, but I'm getting an error with _PrintSetPrinter(), which will not even bring up the dialog box to select the printer. Here's my code (tested):

#include <printMGv2.au3>
#include <GUIConstants.au3>

Opt("GUIOnEventMode", 1)

Local $hwnd, $hButton, $msg, $hp, $mmssgg

$hwnd = GUICreate("Example")
$hButton = GUICtrlCreateButton("click me to print", 20, 20)
GUISetOnEvent($GUI_EVENT_CLOSE, "Quit")
GUISetOnEvent($GUI_EVENT_PRIMARYDOWN, "Print")
GUISetState()

$hp = _PrintDLLStart($mmssgg) ; open the print dll

While 1
WEnd

Func Print()
    Local $selected
    If $hp = 0 Then ; if we couldn't open the dll
        MsgBox(0, "", "Error from dllstart = " & $mmssgg & @CRLF) ; tell us
        Return ; get out
    EndIf
    $selected = _PrintSetPrinter($hp) ; set the printer
    MsgBox(0, "", $selected)
    _PrintDLLClose($hp) ; close the dll
EndFunc   ;==>Print

Func Quit()
    Exit
EndFunc   ;==>Quit

It works just fine for me. You're declaring variable $mmssgg, and you use it in your _PrintDLLStart function, but you never define it. You need to point it to the dll.

[MikahS]

$mmssgg = "C:\Windows\System32\printMG.dll"

 

Doesn't work, am I just stupid or what? hah

Also, this is from Martin's example.

#include 'printMGv2.au3'
Global $hp
Local $mmssgg,$marginx,$marginy
$hp = _PrintDllStart($mmssgg);this must always be called first
if $hp = 0 then
    consolewrite("Error from dllstart = " & $mmssgg & @CRLF)
    Exit
endif
MsgBox(0,'version of dll',_PrintVersion($hp,1))
;MsgBox(0,'result from set printer = ',_PrintGetPrinter($hp));choose the printer if you don't want the default printer
;Exit
;$newselect = _PrintSelectPrinter($hp,"\\MOSAIC1\EPSON Stylus Photo 895")
$newselect = _PrintSetPrinter($hp)
MsgBox(0,'result from set printer = ',_PrintGetPrinter($hp));choose the printer if you don't want the default printer

EDIT: This example works, which confuses me, as I took this almost word for word.

Don't put the DLL in the system32 folder, you would probably need to use #RequireAdmin if you do. Also, the first parameter for _PrintDLLStart is not the path to the file, it's the variable used to hold any error message, the second parameter of that function is where you'd need to put the file name and path to the DLL. By default, that function looks for the DLL in the script's folder.

Thank you BrewMan! I moved the .dll and changed the params around to let $mmssgg catch errors and a var $pathDLL to specify the path to the .dll. After that, it brought the dialog box up just as it is suppose to.
