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

6 posts in this topic

#1 ·  Posted (edited)

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.

$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.


If I posted any code, assume that code was written using the latest release version unless stated otherwise. Also, if it doesn't work on XP I can't help with that because I don't have access to XP, and I'm not going to.

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. :D

      Most print preview solutions use the MFC Doc/View architecture which limits it usefulness outside of c++. I found an article where a Delphi programmer used Enhanced Meta Files wrapped in a custom header and packaged together to create a print preview control. After a little more searching, It looks like using EMFs is a solution that would work.
      Some people suggest to create the document in Word or HTML and use Word or a browser to view it. Indeed, I have rendered documents to HTML and used the IE UDF to display the contents and/or print them. Not quite as ideal as one would like.
      Using GRS's printwin.au3 as a start, I came up with a print preview solution which others may be able to expand upon

      This baby can do almost any language! I found Gleany on this site and set it up on a fresh win10 install. all i would need to do to make it build an exe of the search files app we discovered is the .NET Target Framework download to build 100 % but the exe works and generates! You also need to add the path the the version of csc.exe that you want to run. MSBuild is part of .NET and can read your .csproj file.
      YOU can develop .NET OR C/C++ on this baby!
      Super lightweight (fit for crappy laptops), and you can use any dev compilers you wish, Ming, MS, etc, whatever.
      To use the build, you need to open the csproj file, else, to check your syntax it can compile individual files as well. The warning are because I do not have the .NET 4.6 Targeting Pack installed... LOL, and I could get rid of the Core warning, yes, I did not want to build a .NET Core.dll I wanted a live x64 exe! Told you MSBUILD could handle .CSPROJ, .VBPROJ, and all others Microsoft. Don't let Visual Code or Visual Studio slow you down, although, this works with Visual Code as well but there is only debugging in CORE.DLL projects

      Hello all!
      I use Autoit for a while, already made some automation for a TV station's master control room with it. I made a UDF to easily work with PAL timecode and time with milliseconds, convert, add or subtract them. Feel free to use it if you want something like this

      Howdy, this is my first post, massive fan of autoit. 
      I've searched and tried and I would just like people who are better at this than me to let me know if this is even a thing.

      I'd like to perform just a variable. For example, it would be. *see inserted code*
      So what i'm wanting is, create the constant $test, and that variable would be what is followed after the = . Then perform the _FileCreate. Then perform the variable.  Logically or in my head rather.. That variable is declared and is equal to what it is set to above, therefore just placing the variable plainly in the script, it should be equal to what it was declared as.  So what am I doing wrong, and or how can I have autoit just perform the variable.  

       
      #include <File.au3> Const $test = FileWriteLine(@DesktopDir & "\Log.txt", @CRLF ) _FileCreate(@DesktopDir & "\Log.txt") $test
