Hi,
with AttachedImageEnView set, ImageEnView.PdfViewer.ImportPages correctly adds thumbnails in ImageEnMView. But meanwhile the selected thumbnail remains unaltered, the value of ImageEnMView.SelectedImage changes to the last idx.
Example:
Before ImportPages:
ImageEnView.PdfViewer.PageCount = 2
ImageEnMView.SelectedImage = 0
ImageEnMView highlighted thumbnail = 0
Atfer ImportPages:
ImageEnView.PdfViewer.PageCount = 7
ImageEnMView.SelectedImage = 6
ImageEnMView highlighted thumbnail = 0

Yes, this is resolved in 10.0.2. You can email me for it.

Hi Tiago
This works fine for me:
// Import all pages from a stream
fs := TFileStream.Create('d:\test.pdf', fmOpenRead);
try
fs.Seek(0, soEnd);
fs.Position := 0;
ImageEnView1.PdfViewer.ImportPages( fs, '', ImageEnView1.PdfViewer.PageCount );
finally
fs.Free;
end;

this does not work for me, I have the same error already reported, here is a print of my code.
try
ImageEnView1.PdfViewer.SaveToFile('c:\xerife\certtmp.pdf');
fs := TFileStream.Create('c:\xerife\certtmp.pdf', fmOpenRead);
fs.Seek (0, soEnd);
fs.Position := 0;
ImageEnView3.PdfViewer.Enabled := true;
ImageEnView3.PdfViewer.ImportPages(fs, '', ImageEnView1.PdfViewer.PageCount);
stream := TMemoryStream.Create;
ImageEnView3.PdfViewer.SaveToStream(stream);
stream.Position := 0;
ImageEnView2.IO.LoadFromStreamPDF(stream);
ImageEnView2.Update;
ImageEnView2.BringToFront;
finally
fs.Free;
end; |

Hi
Does it work if you don't call SaveToFile directly before creating the stream (may be a file locking issue)?

Hi Tiago
Are you sure that PDFViewer is enabled for all of your ImageEnViews? This works fine for me (new project with two TImageEnView components):
ImageEnView1.PdfViewer.Enabled := True;
ImageEnView2.PdfViewer.Enabled := True;
ImageEnView1.IO.LoadFromFilePDF( 'D:\file1.pdf' );
ImageEnView2.IO.LoadFromFilePDF( 'D:\file2.pdf' );
ImageEnView1.PdfViewer.ImportPages(ImageEnView2.PdfViewer.Document, '', ImageEnView2.PdfViewer.PageCount);

I'll try to be more clear, I believe you don't understand me.
I need to copy a SINGLE SPECIFIC PAGE from one TImageEN to another TImageEN
I DON'T WANT to copy the entire document just a single page, in this case the last page.

DeletePages does not work either, listIndex occurs when deleting in some indexes, for example: in a page with 45 pages "listIndex error" on page 25....

Hi Tiago
To copy a single page you need to pass the page index, e.g.
// Import fifth page (zero-based index)
ImageEnView1.PdfViewer.ImportPages(ImageEnView2.PdfViewer.Document, [4], ImageEnView1.PdfViewer.PageCount );
// Import fifth page (text string - 1 based)
ImageEnView1.PdfViewer.ImportPages(ImageEnView2.PdfViewer.Document, '5', ImageEnView1.PdfViewer.PageCount );
If the second PdfViewer has not been used, it needs to be initialized using NewDocument. I will make this automatic for the next update, e.g.
// Assign fifth page of PDF to ImageEnView1
ImageEnView1.PdfViewer.Enabled := True;
ImageEnView2.PdfViewer.Enabled := True;
ImageEnView2.IO.LoadFromFilePDF( 'd:\file.pdf' );
ImageEnView1.PdfViewer.Document.NewDocument();
ImageEnView1.PdfViewer.ImportPages(ImageEnView2.PdfViewer.Document, [4], ImageEnView1.PdfViewer.PageCount );

Also, I cannot reproduce the list index error. Are you using 10.2.0? What steps should i take to reproduce?
