Dynamsoft TWAIN Products

Hi Robert/Catherine,
We're using the Dynamic Web TWAIN 4.2 for our ASP/SQL web application.
Our solution's based on your ASP example, using the files clsupload.asp, scan.asp, and imageupload.asp.

When a user hits the scan button, the control pops up a progress bar for the scanner. If the user hits cancel, the scanning operation is terminated.
However, if the user clicks the scan button again on the page, nothing happens.
Refreshing the page is the only way to make the Scan button work again.

Here's the javascript function for the Scan button:

function btnScan_onclick()
{
frmScan.DynamicWebTwain1.IfShowUI=0;
frmScan.DynamicWebTwain1.AcquireImage();
}

We're using the HP ScanJet 4850.

Any ideas?

Thanks.

You need to close the current data source before acquiring images again.



Thanks.
