scan task

[ccnguyen]

Hi all,

I used a perl script to trigger a scanner to create a pdf file and store it a specific loaction (predefined in the script). This process seemed to be working OK if I ran the script from window command line. However, when I try to run this script from a browser, nothing is happening at all. Please help....

post your code or a link to it if it's too long. Could be a path or permissions problem.

Here is the code that I used :

#!perl
use Win32::Scanner::EZTWAIN;
my $scanner = new Win32::Scanner::EZTWAIN();
$scanner->select_image_source();
$scanner->acquire_to_file("C:\\ScanTest\\test2.pdf");

exit;

I used IIS service to run perl.

Thanks

I suggest you read the module documentation and check the return value of the acquire_to_file() method. The module document lists the return values you can use to help determine whats happening:

The problem does not lie on the 'acquire_to_file()' method but the ' select_image_source(); '. When the whole script is ran from the command line, the return value is 1, which mean that a pop window will show up for user to choose which image source installed on their PC. However, when I ran the script from the browser, the process will be stop at this select method and will not continue and no popup window for user to choose the image source. I really appreciate for any kind of help...
Thanks

Hi.
This might seem dumb.
But is your sacnner connected to your web server computer? When running on the browser, the server will be running the code, hence search the image source from its ports, not from the client's.
