Why can't I open pdf files from Delphi

[petertickler]

I am having trouble opening a pdf file via my Delphi application, even though I am using the same
approach as I have used sucessfully to open Powerpoint, Word and Excel files.

I have set up a new form, put a Tpdf component on it, declared a private Tpdf called
NewPDFapp, and created as public open procedure which reads thus:

procedure TfmAcrobat.Open(pdfFile: OleVariant);
begin
NewPDFapp := TPdf.Create(Self);
NewPDFapp.src := pdfFile;
NewPDFapp.Visible := True;
end;

However this does not work. When I try to open a pdf file, Acrobat appears
to open, but then it disappears and the system locks up.

Any bright ideas as to why this might be happening?

Is this some 3rd party component? just I don't remember seeing a Tpdf component in Delphi. Robertio

It comes with Delphi Enterprise. All you have to do is indstall the type library for Acrobat to access it. And I put

PdfLib_TLB

in the

uses

clause.

Do Adobe know about this?.
Or is it why Delphi is getting so pricey these days?
