Update code uploaded

Just update the code on the first post.

What's new:

' Mar 22, 2009 - Version 0.05 by Marc Giao
' Added some error checking
' Added printing (with input from Hans Rietveld)
' Added window resizing

If you compile the code, you'll need an unlock code and the PowerBASIC include file. You can get one by downloading the trial demo from here:

http://www.quickpdflibrary.com/produ...kpdf/trial.php

To run the compiled program, your own or the one include, you'll also need the "Quick PDF Library DLL" included with the trial demo above.

Code and comments welcome

Hi Marc.

A small add-on to make "Set Up" working.

Code:

GLOBAL LibInstance  AS LONG
GLOBAL DocId        AS LONG
GLOBAL PrintSel     AS STRING ' Printer to use for printout

And:

Code:

XPRINT ATTACH DEFAULT
PrintSel = XPRINT$
DIALOG SHOW MODAL MainHndl&, CALL OnEvent_MainDlg

Replace XPRINT$ with PrintSel (4 times)

And:

Code:

       CASE %PrintSetup
            XPRINT ATTACH CHOOSE
            PrintSel = XPRINT$
            IF TRIM$(PrintSel) = "" THEN
                XPRINT ATTACH DEFAULT
                PrintSel = XPRINT$
            END IF
        CASE %PrintPDF

Hi Marc.

You wrote

Code and comments welcome

The code is already in the posting above.

Here is some comment.

If you want to continue with the PDF Viewer, and I think that would be
a good idea, I have the following suggestion.

Why not change the library version for the activex version.
The new compiler, PbWin9 has everything we always want to use those dll's.
The library version that you are using now, depends on the includefile with is
produced by Rowan.
If he got to few response from the PBasic users, he might stop with producing
this file. And this includefile could have some errors, as we have seen before.
If you want to see how it is done, take a look at my earlier posting about this subject.
If you want to change and need some help, just ask.

The second comment is about my add on for printing.
In this case I use the PBasic printerfunctions. I think this is the fastest and
easiest way to do this job.
On the other hand there is a build in function in QuickPDF to render the page
to a device. It is the same function used to make the preview on the screen.
In that case it is possible to use scaling for the printout, but is this usefull ?
And then there is one small issue to solve, the DPI from the screen is much
lower than the DPI from the printer.
Some calculation must be done to keep the same size.

I have done this already and the results are good, not better.
So if you want to know more, ask again.

Keep on going with the PDF Viewer.

Hans Rietveld.

Add selected printer to the info window.

Add to the 4th case statement in: CALLBACK FUNCTION OnEvent_Print( ) AS LONG

Code:

                PrintSel = XPRINT$
            END IF
            CONTROL SET TEXT CB.HNDL, %StateLog, GetDocumentInfo( ) ' Update infoscreen
        CASE %PrintPDF

Add to function: FUNCTION GetDocumentInfo( ) AS STRING

Code:

    Info$ + = "  Height = " + STR$( QuickPDFPageHeight( LibInstance& ) ) + $CRLF
    Info$ + = $CRLF + "Printer:" + $CRLF
    Info$ + = "  " + PrintSel + $CRLF
    FUNCTION = Info$

You're doing some really awesome work here Marc, good work. Building a PDF viewer using PowerBASIC that eveyone can use is going to benefit heaps of people.

Conflict found and fixed in sample code

Hi, I downloaded this program so I could play with the Debenu PDF Library and found the sample code provided caused the DISPLAY OPENFILE command to crash.

I found the global variable DocID in the sample program needed to be changed to avoid the crash. I changed mine to gDocId1 and that seemed to work.

Evidently there must be a conflict with that variable when calling DISPLAY OPENFILE.

The crash occurred sometimes when calling DISPLAY OPENFILE but mostly as soon as the open file dialog closed and the PDFView program started to execute.

I'm running PBWin10.

Hope this saves someone else some time.

Ken

Some highly relevant info ..

If you compile the code, you'll need an unlock code and the PowerBASIC include file. You can get one by downloading the trial demo from here:

From the linked page:

The evaluation version is fully functional for 30 days after the date of first installation.

You can hit the "Purchase Now" link and from that learn the a full license will cost you $499.00
