 Posted: Tue Jan 11, 2005 3:59 pm Post subject: Opening PDF files in Delphi 6 |
 |
|
I am trying to open PDF files from within my delphi 6 application. I have done similar things for other types of file (Word, Excel, etc), but the same approach won't work for PDF files.
So I have put a Tpdf component on my form, then two lines of code thus:
type
TfmAcrobat = class(TForm)
Pdf1: TPdf;
private
{ Private declarations }
NewPDFapp: Tpdf;
public
procedure Open (pdfFile: OleVariant);
{ Public declarations }
end;
var
fmAcrobat: TfmAcrobat;
implementation
{$R *.dfm}
{ TfmAcrobat }
procedure TfmAcrobat.Open(pdfFile: OleVariant);
begin
NewPDFapp := TPdf.Create(Self);
NewPDFapp.src := pdfFile;
end;
When the open code runs, Acrobat Readers appears to start loading, then it disappears and the file is not opened (the application just hangs). I have a feeling this is a known problem. Does anyone out there know the solution?!
Thanks.

SNIP wrong code

You are doing it WRONG.
Since you imported the Type Lib, just drop the TPDF on your form and set
it's src property to the filename you want to open.

I have tried that and it still doesn't work.
I have also tried opening the files with ShellExecute, thus:
ShellExecute(0, 'Open', PChar(pdfFile), PChar(''), PChar(''), SW_SHOWNORMAL);
This doesn't work either. That is to say, it doesn't show the file - however Acrobat appears to open, and then disappears, and the file I am trying to open never appears. I also test for success, and it says it has been successful.
I can open a pdf file via Windows Explorer by double clicking on it.
This leads me to think there is something odd in the way Delphi and Acrobat reader interact, and I wondered if this was a known problem, and if so what was the solution.

does the Acrobat Reader work in other ActiveX containers like Visual
Studio.net?
it might be an OLE Control, not supporting the ActiveX stuff so try dropping
it inside a TOleContainer component

No, try reinstalling the reader, first.
