Hi,

I am using 13.1.0 version of your fantastic tool.

While using TIEDBMultiBitmap, when I have a new query proviging a nex set of records, I have many time a message indicating that IDX in info := fIEMBitmap.GetImageInfo( idx ); is of limits while charging the images.

Project xxx.exe raised exception class EIEException with message 'Index out of bounds (0)'.

Then all images loaded are with a default icon and not the expected thumbnail.

Can you please help ?

My initilisation :

ImageEnView1.SetModernStyling;
fDBMBitmap := TIEDBMultiBitmap.create( udm1.DS_fi_Img , '', 'CHEMIN_CPL', dmAllRecords );
//The file name is complete in field CHEMIN_CPL

fDBMBitmap.ImagePath := '';
fDBMBitmap.FollowDBCursor := True;
fDBMBitmap.AutoLoad := true;
fDBMBitmap.mode := dmAllRecords ;

ImageEnView1.SetExternalMBitmap( fDBMBitmap );
imageEnView1.DefaultTopText := iedtCustom;


Best regards.

Hi Nigel,
I think that's what I did in the begining.
That was the way I had all the error messages that I don't have with the deprecated component.

Best regards

Hi

You probably should not use TImageEnDBView as it is a deprecated component, instead use a TImageEnView and sets its external bitmap to a TIEDBBitmap:

Regarding the page index, you would set:

https://www.imageen.com/help/TIOParams.ImageIndex.html

But I don't know that it will be honored for database loading.

New question with this enviroment, how do I display a specific page in the TImageEnDBView, if in my TIEDBMultiBitmap I have a multi pages PDF file ?
When I had a linked TImageEnMview it was automatic, but now I do not know how to do it.

OK that was it.

So what I did, I removed the link in the TImageEnMview in AttachedImageenView.
I replaced the TImageenView that was originaly linked and replace it with a TImageEnDBView.
The TImageEnDBView is linked (Data source and Field name) the same as in my declarations :

ImageEnView1.SetModernStyling;
fDBMBitmap := TIEDBMultiBitmap.create( udm1.DS_fi_Img , '', 'CHEMIN_CPL', dmAllRecords );
//The file name is complete in field CHEMIN_CPL

fDBMBitmap.ImagePath := '';
fDBMBitmap.FollowDBCursor := True;
fDBMBitmap.AutoLoad := true;
fDBMBitmap.mode := dmAllRecords ;

ImageEnView1.SetExternalMBitmap( fDBMBitmap );
imageEnView1.DefaultTopText := iedtCustom;


and It works like a charm.
No ore messages. :-) YaY !!

It seems to be the same problem as Mr ioster.
