Problem with ShellExecute. 2

[delphiman]

I have happily been using the code below .... but suddenly (having made some changes to my software) instead of producing my HelpFile I merely end up with the folder containing the Help File.

Can someone throw some light on this please?

(By the way I do have ShellAPI in the uses clause. :- )


procedure TfrmMainForm.btbtnHelpClick(Sender: TObject);
begin
ShellExecute(hInstance, 'OPEN', PChar(Application.HelpFile), nil, nil, sw_Normal);
end;

Make sure that

Application.HelpFile

has the help file name, not just the directory. It is just a string (i.e. not validation) and can get garbled.

Hey fellllaaaaaaaaaaaaasss!!

It helps to go to Projects->Options->Application and
tell poor old Delphi in "Äpplication Settïngs" that
one has deemed it appropriate to call up a Help File
now and then.

Why didn't you lads remind me that I had re-installed Delphi (not to mention W2K) in between??

Geeeeeee!! You could have been more helpful!!

Nevertheless you both merit a star - for pointing me in the right direction.

I feel such and ass!! :-(

The only reason we knew the probable cause is because we have made this mistake (and so, so many more).
