PDF Editor 6.0.318 - Programatically print a PDF silently without print UI. SOLVED

[docu-track99]

I have a PDF already loaded via code and the below code stopped working and it used to with build 318. Can you help guide me in the right direction to fixing this, please and thanks?
The line "op = pdfCtrl.Inst.CreateOp(2553)" produces Nothing and fails when it is called at Dim input As "PDFXEdit.ICabNode = op.Params.Root("Input")"

Private Sub PerformSilentPrint()

Try
Dim op As PDFXEdit.IOperation = Nothing
op = pdfCtrl.Inst.CreateOp(2553)

Dim doc As PDFXEdit.IPXV_Document = pdfCtrl.Doc
Dim input As PDFXEdit.ICabNode = op.Params.Root("Input")
input.Add().v = doc

Dim opExecFlags As Integer = 0
pdfCtrl.Inst.AsyncDoAndWaitForFinish(op, CUInt(opExecFlags))

Catch ex As Exception
End Try

End Sub

Hello docu-track99,

You had posted in the end user forums - and those are not as actively monitored by our devs as the SDK section.
I've now moved your topic to the correct place and will ask a colleague to take a look!

Cheers,

Hello docu-track99,

The reply I got was that you should not use number ID values as those will differ from build to build.

Ok, I need help with changing my code then. If I can't use the number then what should be the proper process or how can I get the ID to use?

Thanks,
Steve.

Hello Steve,

The proper way would be to use the same method as you used to get the 2553 number - Str2ID method.

Cheers,

Thanks for your response. I have used the Str2ID before but I need the string to pass into it. The code I have shared with you came from you so I never new what the ID represented as a string. Please let me know.

Thanks.

Hello Steve,

I could not have passed the number value like that as a parameter. It probably might of been a numerical variable that was converted from the string representation of the ID. Though there still was an ID that it was converted from. Anyways, what operation are you using here?

Cheers,
Alex

Hi,

The code was given to me by this forum to use about a year ago but since we upgraded to 318 it stopped working. I really don't know what 2553 is supposed to represent that is why I am asking you to for your assistance so I can get it working again. The code provided allowed our program to print an opened PDF silently without the print dialogue appearing.

Does this make sense now?

Hello Steve,

Then it seems that it is the op.document.printPages.

Cheers,
Alex

It works: Here is my working code.


Private Sub PerformSilentPrint()

Try
Dim op As PDFXEdit.IOperation = Nothing
op = pdfCtrl.Inst.CreateOp(pdfCtrl.Inst.Str2ID("op.document.printPages"))

Dim doc As PDFXEdit.IPXV_Document = pdfCtrl.Doc
Dim input As PDFXEdit.ICabNode = op.Params.Root("Input")
input.Add().v = doc

Dim opExecFlags As Integer = 0
pdfCtrl.Inst.AsyncDoAndWaitForFinish(op, CUInt(opExecFlags))

Catch ex As Exception
End Try

End Sub
