Hi,

Can someone help please? I’m new to all this so please bear with me if I’m doing something daft. I’m running Windows 7 64 bit.

I downloaded the trial version and registered the ActiveX dll file called “QuickPDFAX0816.dll” without any problems.

I then opened Microsoft Access and entered the following VBA code (which is based on the code given on http://www.quickpdflibrary.com/help/getting-started-activex.php - ) and, to my delight, it all ran perfectly and I created my first pdf. The VBA code is:

Public Sub TestQpdf()

Set PDFLibrary = CreateObject("QuickPDFAX0816.PDFLibrary")

If PDFLibrary.UnlockKey("insert_license_key_here") = 1 Then

Call PDFLibrary.DrawText(100, 500, "Test Text")

Call PDFLibrary.SaveToFile("C:\users\DAN\DeskTop\Test.pdf")

End If

Set PDFLibrary = Nothing

End Sub

I then tried the code below (which is based on the code given on http://www.quickpdflibrary.com/tutorials/merge-pdf.php) but it crashes at the line PDFLibrary.LoadFromFile (Doc1) and the VBA error message is run-time error’450’: Wrong number of arguments or invalid property assignment.

Public Sub TestQpdfMerge()

Set PDFLibrary = CreateObject("QuickPDFAX0816.PDFLibrary")

If PDFLibrary.UnlockKey("insert_license_key_here") = 1 Then

Doc1 = "C:\users\DAN\DeskTop\PDF1.pdf"

Doc2 = "C:\users\DAN\DeskTop\PDF2.pdf"

Doc3 = "C:\users\DAN\DeskTop\PDF3.pdf"

PDFLibrary.LoadFromFile (Doc1)

MainDocID = PDFLibrary.SelectedDocument()

PDFLibrary.LoadFromFile (Doc2)

AppendID = PDFLibrary.SelectedDocument()

PDFLibrary.SelectDocument (MainDocID)

PDFLibrary.MergeDocument (AppendID)

PDFLibrary.SaveToFile (Doc3)

End If

End Sub

I suspect I’m missing the point somewhere and should be grateful if someone could point me in the right direction, ideally with a few lines of VBA that will work.

Thank you.

The "wrong number of arguments" error message is a clue - the LoadFromFile documentation mentions that a second argument is required (password). If your PDF file doesn't have a password, then use pass "" as the second parameter (e.g. PDFLibrary.LoadFromFile(Doc1, ""))

The LoadFromFile method changed to include the password parameter when 8.x was released, so the sample code that you have is out of date. There may be other changes too, so it is a good idea to review the documentation for any methods that you are calling.

Thanks. I've tried what you suggested, i.e. PDFLibrary.LoadFromFile(Doc1, ""), but the line immediately turns red indicating a syntax error. I've read through the documentation but can't see anything to help.

Hi Supertension,

Just in case you're wondering -- I made a small edit to your post to remove the license key from the sample code.

Cheers,

- Rowan.

Rowan, Noted. I'll make sure I don't include it in any future posts.

Can you help me solve my problem? Thanks

Maybe you could try

Password = ""

PDFLibrary.LoadFromFile(Doc1, Password);

PDFLibrary.LoadFromFile(Doc1, NullString);

This is a VBA problem but I don't have any experience in VBA.

Andrew, Thanks but no joy. I still get the syntax error.

It seems that you need to store the return value. The VBA error message didn't help much. What a strange language.

Andrew.

Sub Help()

Set PDFLibrary = CreateObject("QuickPDFAX0816.PDFLibrary")

If PDFLibrary.UnlockKey("put your key here") = 1 Then

Doc1 = "f:\downloads\1.pdf"

Doc2 = "f:\downloads\2.pdf"

Doc3 = "f:\downloads\vba.pdf"

ret = PDFLibrary.LoadFromFile(Doc1, NullString) // Works

MainDocID = PDFLibrary.SelectedDocument()

ret = PDFLibrary.LoadFromFile(Doc2, "") // Works

AppendID = PDFLibrary.SelectedDocument()

PDFLibrary.SelectDocument (MainDocID) // strange it doesn't need the return value here.

PDFLibrary.MergeDocument (AppendID)

PDFLibrary.SaveToFile (Doc3)

End If

End Sub

Andrew, Perfect. Many thanks for your help. I would never have worked that one out for myself.

Hi Rowan,

Been reading and testing most of your Delphi Sample how to merge Multiple PDF files into one. I am now using a trial version of the Quick PDF Library. Regarding your PDF Merging via Stream, i cannot make it work.

uses ***QuickPDF0816;

function MergeStreamsViaMergeDocument(FirstStream, SecondStream,

OutputStream: TMemoryStream): Integer;

var

doc1, doc2: Integer;

begin

with TQuickPDF.Create do

try

FirstStream.Seek(0, soFromBeginning);

LoadFromStream(FirstStream);

doc1 := SelectedDocument;

SecondStream.Seek(0, soFromBeginning);

LoadFromStream(SecondStream);

doc2 := SelectedDocument;

SelectDocument(doc1);

MergeDocument(doc2);

OutputStream.Seek(0, soFromBeginning);

SaveToStream(OutputStream);

finally

Free;

end;

ERROR MESSAGE APPEARED ON: " LoadFromStream(FirstStream);"

ERROR MESSAGE: "NOT ENOUGH ACTUAL PARAMETERS."

Please help. Thank you in advance.

Vid, MULTISYSCORP

A quick read of the "Quick PDF Library 8.16 Reference Guide.pdf" will reveal that LoadFromStream also requires a password parameter as of QPL 8.xx. The PDF file can be found in the Quick PDF installation directory.

http://www.quickpdflibrary.com/help/quickpdf/LoadFromStream.php - http://www.quickpdflibrary.com/help/quickpdf/LoadFromStream.php

LoadFromStream(FirstStream, Password); // add the password parameter - can be blank ie. ""

It would also be helpful to know what development system you are using.

Andrew.

Hi Andrew, thank for your help. It runs without error now. I want to put the merge command to a BUTTON? Thanks again...

..."to a BUTTON"...

You'll find it here:

"to a BUTTON" is a Delphi problem and not a Quick PDF Library. This is one of the very first things that is taught in any Delphi Basics 101 course. ie http://www.delphibasics.co.uk/Article.asp?Name=FirstPgm - http://www.delphibasics.co.uk/Article.asp?Name=FirstPgm

1. Add a button to your form

2. Double click the button and the following code is shown

procedure TForm1.Button1Click(Sender: TObject);

begin

end;

3. Paste the Quick PDF Library code we have given you between the 'begin' and 'end' statements.

Andrew.
