Lock problem during the "exporting" of a PDF file list

[Stemonte]

Hi,

I have used and modified your API Demo to export a pdf file list into PDF/A files, but the first iteration stops because Adobe start itself but not close itself. The iteration continues to the next step only when I close manually Adobe, with the same problem of the prior step.

How solve it?

Thanks.

Hello Stefano,

Try setting RunApp to False, as the default Value of True, will launch your default application for Viewing PDF files after the printing of the current document is complete, and Adobe's Acrobat on your machine is most probably locking the file.

Stefan

Hi,

RunApp is already set to False.

this the Delphi code from ApiDemo App:
[...]
PDFPrinter.Option['Save.RunApp']:=False;//cb_RunViewer.checked;
//
PDFPrinter.Option['Save.File'] := ed_Dest.Text;
PDFPrinter.Option['Save.SaveType'] := 'Save';
PDFPrinter.Option['Save.ShowSaveDialog'] := 'No';
PDFPrinter.Option['Save.WhenExists'] := 'Overwrite';
//
if cb_Compression.Checked then
begin
PDFPrinter.Option['Compression.Graphics'] := 'Yes';
PDFPrinter.Option['Compression.Text'] := 'Yes';
PDFPrinter.Option['Compression.ASCII'] := 'No';
PDFPrinter.Option['Compression.Color.Enabled'] := 'Yes';
PDFPrinter.Option['Compression.Color.Method'] := 'Auto';
PDFPrinter.Option['Compression.Indexed.Enabled'] := 'Yes';
PDFPrinter.Option['Compression.Indexed.Method'] := 'Auto';
PDFPrinter.Option['Compression.Mono.Enabled'] := 'Yes';
PDFPrinter.Option['Compression.Mono.Method'] := 'Auto';
end
else //cb_Compression.Checked
begin
PDFPrinter.Option['Compression.Graphics'] := 'No';
PDFPrinter.Option['Compression.Text'] := 'No';
end; //not cb_Compression.Checked
//
PDFPrinter.Option['Fonts.EmbedAll'] := cb_embFonts.Checked;

Hi Stefano,

I asked for help some the guys that are more into it in Delphi programming and they should reply shortly.

Hi Stefano,

Actually when you set "Save.RunApp" to false any of PDF viewers should not be opened. Can you send us your sample project so we can check it here?

[Stemonte]

As asked me, I've just sent You a pm containing my DriverAPI example modified.

Hi Stefano,

As I can see, you are trying to print PDF file using Acrobat Reader. But the problem is that after executing "printto" command Adobe Acrobat Reader remains opened and there is nothing we can do with it. You may try to close it automatically by sending WM_CLOSE command. Also you may use our PDF-XChange Viewer for printing PDF files which doesn't have such problem.

meaning? ...using same DriverApi example...

Meaning the file is locked and unavailable to other applications as it is still open in another and not fully released.

If you will try to print MS Word document using ShellExecute with "printto" command, you will see that Word will close itself right after printing and this is normal behavior for most programs. Anyway we cannot change this fact, that Acrobat still stays opened after printing.

Sorry, this is ok.

but I was referring to

...you may use our PDF-XChange Viewer for printing PDF files

using DriverApi example.

[Corwin - Tracker Sup]

Well, you may set PDF-XChange Viewer as default viewer for PDF files and use ShellExecute method, or you may use Viewer command line arguments, which has this arguments:
"...\PDFXCview.exe" /printto[:[default=yes|no][&showui=yes|no][&pages=<pagesrange>]] <printername> <filename1> [<filename2> ... <filenameN>]
