Post by joher1988 » Mon Jul 26, 2010 07:33 AM

Hello, I have a litle problem. When i try scan documents paeges one by one, first page scan normal, but next pages don't scan and Twain ErrorCode=DSIsNotOpen.

 
              _twain.SourceIndex = TwainHelper.FindSourceIndex(_twain, options.dataSource);
                _twain.OpenDataSource();
                if (_twain.FeederPresent)
                {
                    if (options.autoFeed)
                    {
                        if (_twain.XferCount != -1)
                            _twain.XferCount = -1;
                        if (!_twain.FeederEnabled)
                            _twain.FeederEnabled = true;
                        if (_twain.AutoFeed != options.autoFeed)
                            _twain.AutoFeed = options.autoFeed;
                    }
                    else
                    {
                        if (_twain.XferCount != 1)
                            _twain.XferCount = 1;
                        if (_twain.AutoFeed != options.autoFeed)
                            _twain.AutoFeed = false;
                    }
                }
                
                _twain.ShowUI = true;
                _twain.DisableAfterAcquire = false;
                while (_twain.AcquireModal()) ;
                twainScanFinished(null, null);
            }
            finally
            {
                _twain.CloseDataSource();
            }
