Hello,

Brother ADS-2700W (at a client's site)

In my app the scan (Acquire) function seems to do nothing with the twain scan button.
As a debugging test, I tried AllAquire and got the same result.
I added the log file to my version of AllAquire and posted the results here below.

I tested the twain driver with the scanner's included paperport software and it works 100%. I also tested the Preview button on the twain screen in AllAquire and it works. I have to use Delphi 2007 (with ImageEn 5.x) for this project.

Thanks, Craig

AllAquire code with log file line added:
procedure TfrmMain.btnAcquireClick(Sender: TObject);
begin
ImageEnMView1.MIO.TwainParams.LogFile := 'ietwainlog.txt';

if ImageEnMView1.MIO.AcquireParams.SelectedSource.API = ieaNone then
begin
messagedlg('You have not specified an acquisition source', mtInformation, [mbOK], 0);
exit;
end;

SaveProperties;
ImageEnMView1.MIO.Acquire; // nothing seems to happen in twain scan!
ProgressBar1.Position := 0;
end;

Hi Craig

A log item reports: "IETW_DS : Source is connected to maximum supported number of applications." Is it possible that another app has locked the device?

Also, can you try inserting a call to FreeResources() in TfrmMain.btnAcquireClick() of the AllAcquire demo:

...
SaveProperties;
ImageEnMView1.MIO.TwainParams.FreeResources();
ImageEnMView1.MIO.Acquire;
...


Finally, please also try the Twain demo, and let us know if that gives the same result.
