OK, this seems to fix it.

Change

Why did you use StrP for the third parameter of DocumentProperties? Msdn says

msdn DocumentProperties wrote:

pDeviceName [in]

A pointer to a null-terminated string that specifies the name of the device for which the printer-configuration property sheet is displayed.

So it should be ptr.

Anyway congrats, the script run with the 64bit build printed out a red circle. The library seems to be very nice.

I have a question, is this library able to print out a text file and save it as a specified image format? Let's say, I want to create a print view of FileA.txt and save it as FileA.jpg.

Wow, this is great. Many thanks!

Well because

ahk-help wrote:

* or P
(suffix)Append an asterisk (with optional preceding space) to any of the above types to cause the address of the argument to be passed rather than the value itself

so i thought, AHK-Vars are null-terminated strings, so StrP (and Str*) therefore are pointers to "a null-terminated string". And for all i could test (32bit) it worked. Seems 64bit is a bit more demanding.

well for the second part, yes saving as image.files should be doable, as the print is based on a GDI-Device Context. I'm just not shure if there is function for that in the gdip-lib already,
i'll look that up tomorrow, it's late here.
for the first part, i plan to write a wrapper for either the GDI or the GDI+ text-function, but that is future for now. But if you just want to print a text-file to an image-file, you won't need my lib, the gdip.ahk-lib should be enough there is a Gdip_TextToGraphics and a Gdip_SaveBitmapToFile in there.

So thanks again and good night, i'll report again on that topic tomorrow, if you are interested.

No, pPrinterName is containing a string, so it must be

Code:

"Str", pPrinterName
; or 
"Ptr", &pPrinterName

Code:

VarSetCapacity(pDevModeOutput , A_PtrSize, 0)

No, pDevModeOutput isn't a pointer-sized variable, e.g. its size is 1638 for my printer. So you must set the capacity to sizeDevMode.

i'm in the land of confusion now.

i'm totally unsure about the pPrinterName issue.

my opinion about the capacity of sizeDevMode was the same as just me,
but guests version seems to work on both 32&64bit, oposed to mine.

So anyway, i need another test on 64bit, to see if the new proposal works.
Please test this on 64bit and report back:

Moin Zed,

Code:

;   just me proposal   
   sizeDevMode := DllCall("Winspool.drv\DocumentProperties", "Ptr", MainhWnd, "Ptr", pPrinter, "Ptr", &pPrinterName, "Ptr", 0, "Ptr", 0, "UInt", 0, "Int")
   MsgBox, 0, sizeDevMode, %sizeDevMode% ; for testing only
   VarSetCapacity(pDevModeOutput , sizeDevMode, 0)
   out2 := DllCall("Winspool.drv\DocumentProperties", "Ptr", MainhWnd, "Ptr", pPrinter, "Ptr", &pPrinterName, "Ptr", &pDevModeOutput, "Ptr", 0, "UInt", 2, "Int")

      
   if ((dmOrientation = 1)||(dmOrientation = 2))
      NumPut(dmOrientation, pDevModeOutput, 44, "Short")
   if dmCopies is integer
   {   
      if (dmCopies > 0)
         NumPut(dmCopies, pDevModeOutput, 54, "Short")
   }
   if ((dmColor = 1)||(dmColor = 2))
      NumPut(dmColor, pDevModeOutput, 60, "Short")
;;;64 possible error abouve POINTL struct, is it a pointer?   
   out3 := DllCall("Winspool.drv\DocumentProperties", "Ptr", MainhWnd, "Ptr", pPrinter, "Ptr", &pPrinterName, "Ptr", &pDevModeOutput, "Ptr", &pDevModeOutput, "UInt", 10, "Int")

is working on Vista 32 with AHK 1.1.05 U32 and Win7 64 with AHK 1.1.05 U64

I just chenged it to avoid to pass -1. So if sizeDevMode works, it should be it.

I'd like to here an opinion or correct infomation from an expert whether it should be UintP or PtrP mentioned in this post.

That would be great to see. We would be able to create a web page screen short from it.

interesting, confusing, but
everything seems OK now.
so thank you all for your help.
this is very probably the final version:
SGDIPrint.ahk

Code:

code removed due to protest.
http://www.autohotkey.com/forum/viewtopic.php?t=81795

so i'm going to work on the aditional functions.
i'll start with getting a bitmap-copy of the printer-dc for previews and saveouts. then i'll do a text- and bitmap-put function.
Feel free to post more ideas, but don't expect to much.

btw:

Hi Zed,

there's still (at least) one 64-bit issue in your script:

Code:

   ; Get the newly created printer device context.
   if !(hDC := NumGet(PRINTDIALOG_STRUCT,16))
      return

should be

Code:

   ; Get the newly created printer device context.
   if !(hDC := NumGet(PRINTDIALOG_STRUCT,A_PtrSize * 4))
      return

hi, i'm back with an extended version of the lib
the new (and more resource-demanding)functions allow to
draw on a GDI+ Bitmap first, so you can preview the print or save it to image-file,
and then copy it to the printer DC.

Again i need some Tester,
could you please test the lib with the new test-script (which saves the print as test.jpg prior to printing).

SGDIPrint.ahk

It's working here on Windows 7 Ultimate 64 bit, AutoHotkey 1.1.05.06 64 bit.

Thanks for all your help.
The SGDIPrint Library seems stable now and is therefore published.
You'll find it here: http://www.autohotkey.com/forum/viewtopic.php?t=81679
