Hello,i want to stop the scan in the ImageEnMView's OnAcquireBitmap,but it can not stop.
For example, I scan 100 sheets of paper. If an error is detected when scanning to the second sheet, I want to stop scanning, but the following code cannot prevent the scanner from continuing to scan. How can I stop scanning the scanner?
procedure TFrmScan.ImageEnMViewAcquireBitmap(Sender: TObject; ABitmap: TIEBitmap; DpiX, DpiY: Integer; var Handled: Boolean);
begin
if CheckError then
ImageEnMView.MIO.Aborting := True;
end;

I uploaded the demo and made comments in the relevant code.

OK, I'll make a simple demo and upload it here. |

Yes, if you want to create a very simple demo that shows the problem, we can test that here.

Hmm, I cannot reproduce that here. We'll need to investigate.

Hello:
I used the Twain driver. |

Hi
Is this using a Twain or WIA driver?

Hello:
my code:
procedure TFrmScan.ImageEnMViewAcquireBitmap(Sender: TObject; ABitmap: TIEBitmap; DpiX, DpiY: Integer; var Handled: Boolean);
begin
if CheckError then
begin
ImageEnMView.MIO.AcquireParams.Aborting := True;
Handled := True;
ShowMessage('there are errors !');
end;
end;
When running this code, a dialogue window will pop up, and the scanner will not stop scanning until all the papers have been scanned. Why? I want to stop scanning when encountering errors and pop up a prompt dialog window. |

If Aborting is set in OnAcquireBitmap it will still add the current image to the MView. To avoid this set:
Handled := True;

but the scanner will scan all the paper! |

Hi
To cancel scanning:
ImageEnMView1.MIO.AcquireParams.Aborting := True;
