|Free/Simple VFP Report To PDF - Print2PDF|
Tuesday, July 23rd, 2002 at 00h24
Here is a free/fast/simple way to create PDF files directly from VFP. This is "black box" code/class that will run a VFP report and output it to a PDF. It will even automatically install any needed components for the user! It's easy to setup and to use! It is very flexible for programmers, easy for end-users, and well documented.
Print2PDF automatically selects the free Adobe Postcript printer driver to create a Postscript file (a temporary file in the VFP temporary path). It then calls the free DLL of Ghostscript to turn that Postscript file into a true PDF file. You can pass in the report name and the output name/path.
This is an fast, free, and elegant solution to PDF generation from VFP.
*** Version 1.1 ***
This update adds the functionality of automatically locating the Ghostscript files. Also, the download now includes Ed Rauh's clsheap.prg.

Added logic to allow the user to install Ghostscript on-the-fly.

Added the ability to read most setting from the .INI file.
Put logic in the Install() method and .INI file that will allow you to install any other program also.
*** Version 1.3 ***
Added support for printing "color" in pdf.
You can change printer resolution on-the-fly.

Complete Demo program (including dbf and report).

++Please be aware that version 1.3 has CHANGED some .ini settings!

|4.||Klaus Hentschel||25/07/2002 09:39||Another question.
Is it possible to create colored PDF? When I print to a PDF everything goes Gray.|
|5.||Mike Albert||08/08/2002 10:14||Sweet code, Paul. It is possible to get color text or shapes but I can't seem to get color images. In foxpro, you can set the color of each item on the form. The key (I think) is using a color printer's PS driver. I'm using the HP Color LaserJet PS (with port FILE under the DETAILS tab) that is included in windows. The only thing I couldn't get color was the image. If anyone figures that out, email me at email@example.com with subject "universal thread" otherwise I won't see it with all the junk mail I get. Thanks again, Paul, this was just what I needed.|
|6.||Paul James||12/08/2002 10:37||Please check out the newest version (1.3). Color printing is now enabled, also several fixes, updates, etc. Thanks - Paul|

|8.||Zlatin Zlatev||15/08/2002 13:37||"Is it possible to create colored PDF?..."
Klaus, use the HP Color LaserJet 8500 PS printer driver for producing the PS output and you will be able to produce colorful PDFs. We use this driver together with ghostscript in our PDF reporting engine.|
|9.||Trish Middleton||10/10/2002 20:17||This was very simple! I was having memory problems with FRX2WORD. This was free and it really works great! It comes out exactly like your report.|
|10.||Michael Brennan-White||06/11/2002 13:39||Wonderful Product. Works much faster than Acrobat for creating pages but is there a way to convert more than the first seven pages of the report to a PDF.
I can send a copy of the report if that would be helpful to diagnose the problem.|
|11.||Claude Fuchs||08/11/2002 08:19||Completely free and it's better than the Acrobat Writer/Distiller! Especially good for web reports...|
|12.||Paul James||08/11/2002 10:39||Debugging Tip:
Most problems are a result of a problem in your VFP report or your printer driver. If you will set the flag in the class so that "Report2PDF" does NOT delete the postscript file (.ps file), you can open the (.ps) file with Notepad and look for error messages. Also, look at my notes about manually creating and converting, because you can manually send your report to the Adobe printer driver (to create a .ps file), then via command-line you can call ghostscript to convert it.
Thanks - Paul James|

|14.||Mike Albert||14/11/2002 14:56||Hey VFP people. Here's the question. If given just a PDF file, how can you print it out without opening the pdf? I'm asking here because I want to be able to print out multiple PDF files programmatically without opening them (hundreds of these bad boys). This may not involve FoxPro or not, but I thought you may know how to do this. Is this a matter of converting the pdf to a .ps file? If so, can I convert a pdf file to something that isn't postscript like PCL5e (postscript is bigger and slower when printing)? Any help is appreciated. Thanks again.
|15.||Paul James||14/11/2002 21:30||One option would be to retain the Postscript file (.ps) when creating the PDF. This class has a property to tell it whether to delete it or not. Then, as you pointed out, the postscript file could simply be "redirected" to a printer port even using something as low-tech as a batch file.
Thanks - Paul James
|16.||Jonathan Finch||02/12/2002 12:35||For printing a .PDF without opening it, calling the Windows API seems to do the trick, assuming acrobat reader is installed. The Foxpro Foundation Classes have an _environ.vcx class library containing a _shellexecute class. Subclassing it with "open" changed to "print" in its Shellexecute method worked for me.|
|17.||Claude Fuchs||16/02/2005 04:34||I've got it working great from activevfp now! Color and everything!! I did modify it slightly to accomodate a vfp web/COM mtdll environment along with reverting back to using the ghostscript dll (along with Ed Rauh's heap class) for scalability reasons...|

Have you ever needed an "on-the-fly" way to "tone down" your color palette to suit the needs of a particular client running 256 colors.
