Hello,
i use follow source code:

OpenImageEnDialog.InitialDir := load_dir;
OpenImageEnDialog.FileName := ofn;
OpenImageEnDialog.FilterIndex := open_filterindex;
if OpenImageEnDialog.execute then
begin
load_dir := extractfiledir(OpenImageEnDialog.FileName);
ofn := OpenImageEnDialog.FileName;
open_filterindex := OpenImageEnDialog.FilterIndex;
.....

when i open the first Image, the view is korrekt wit the last saved Filetype 'PSD'.
See here:


Now i wants open the next image, but the Filetype is no more 'PSD' ??

It's Image Files (*.jpeg;*.png;*.bmp;*.tif;*.gif...)


I select 'PNG' and load a PNG-File, this is OK


Now i wants open a new PNG_Image, but the Filetype is how befor
All Image Files (*.jpeg;*.png;*.bmp;*.tif;*.gif...) ????


Why it' not posible to preselect the last Filetype per set from
OpenImageEnDialog.FilterIndex := open_filterindex
With the laste file type.
What i doing wrong ?
Can anyone help me, with a little source for this.

Hi Klaus

You are better to use FilterDefault rather than FilterIndex:

Hi Nigel,

Thanks, I have that too already tried.
This is the Code:

OpenImageEnDialog.InitialDir := load_dir;
OpenImageEnDialog.FileName := ofn;
OpenImageEnDialog.FilterDefault := open_filterindex;
if OpenImageEnDialog.execute then
begin
load_dir := extractfiledir(OpenImageEnDialog.FileName);
ofn := OpenImageEnDialog.FileName;
open_filterindex := OpenImageEnDialog.FilterDefault;
.....

The result is the same.

I have now found an emergency solution.
If I set the OpenImageEnDialog.FileName := '',
then it works as it should.

Hi Klaus

Sorry, I should have mentioned that setting filename will override FilterDefault (it will default to the extension of the passed filename).

Also, FilterDefault will override FilterIndex.
