How To Display Image directly using ImageEnView component from a TRzFileListBox
I tried using this code but couldn't display the image
ImageEnView1.IO.LoadFromFileJpeg(RzFileListBox1.Items.Strings[i]);
note: *LoadFromFileJpeg just using this because I am selecting jpeg files
thanks

My guess: you need to provide a path to your file.

I'm using TRzFileListBox component which is directly connected to the RzDirectory Tree.
I also tried this ExtractFileName(RzFileListBox1.Items.Strings[i])
but still didn't work

Try this
var
iFilename: string;
begin
iFilename := RzFileListBox1.Items.Strings[i];
if not FileExists(iFilename) then
ShowMessage('The file ' + iFilename + ' does not exist.')
else
begin
ShowMessage('The file ' + iFilename + ' exists. Select Ok to load the file.');
ImageEnView1.IO.LoadFromFileAuto(iFilename);
if ImageEnView1.IO.Aborting = True then
begin
ShowMessage('ImageEn can not open the picture. The picture may be defective.');
end;
end;

Martin,
of course there is an alternative: use a simple TWebBrowser to load the PDF.

Hi Uwe
Yes, this is true, but you need to ensure that Acrobat has been installed on the client.

You're right, Nigel - I forgot to mention that the Acrobat Reader has to be installed on the target system. Although that shouldn't be an issue since most users have the software installed anyway these days. An error check is of course necessary.

Hi Uwe
Yes, it is rarely a problem. I used this technique to display PDF files in an application in my pre-ImageEn days, and it worked well.
In this case however, he is looking to display thumbnails, which means a third party library such as Ghostscript.
There is also another way, but it would require some work and a paid license from a third party. Email me, Rizal, if you want more info.
