Hello
I use this code:
if OpenImageEnDialog1.Execute then ImageEnView1.IO.LoadFromFile(OpenImageEnDialog1.FileName) else exit;
Problem:
No matter what I do to the filter settings, the dialog opens with jpg only.

This method opens with the common graphics as a filter and is therefore good:
with ImageEnView1.IO do LoadFromFile(ExecuteOpenDialog('','',true,0,'') );
Problem:
I cannot, or do not know how to apply the "if..then..else exit;

Any help on forcing the filter or applying the i-then statement?
Thanks
Piet

Hi Piet

Is TOpenImageEnDialog.AutoSetFilter set to true?

If you click the down button on the file type box, what is exactly is listed?

Hello Nigel,
I had it true, then false. I have have set the DefaultFilter to 0, to 1, to -1. Nothing changes.
I have set the FilterIndex to 0, 1, and -1. Nothing changes.

If I click the dropbox, the filters are listed exactly as they are in the filter edit edit feature.

Sorry I may have misunderstood you, are you saying that you have a complete filter (File of Type has all the various types), but it defaults to JPEG?

To have it default to all common image types set FilterDefault to -1 (= no selected type) and FilterIndex to 1 (first item is selected).

You can also use TImageEnIO.ExecuteOpenDialog as follows:

sFilename := ImageEnView1.IO.ExecuteOpenDialog('', '', false);
if sFilename <> '' then
  ImageEnView1.IO.LoadFromFile(sFilename);

Thanks Nigel,
the combination AutoSetfilter=false, Filterdefault=-1 and FilterIndex=1 did the trick.
