You'd need to automatically open up the scanner's TWAIN interface, fire off a scan automatically and save it on the webserver somewhere automatically (off the top of my head). How do you do that? Probably with a lot of nasty C code!?

Hi
I’m converting a project from visual studio 2003 to visual studio 2005. The problem is:
In the 2003 project I got a folder (called businessLayer) containing all the .cs business classes and one of these classes is referencing a user control in another folder after converting the businessLayer folder became under app_code folder so it can’t see the folder containing the user control so I put the cs files in a folder (also called businessLayer) out of the app_code folder but the all the controls can’t access the new folder out of app_code while they can see another folder containing another user controls.
So what can I do to overcome this problem, any idea

Why is your business layer using a UserControl? You would be better to look at changing that, ideally the business logic doesn't need to have access to anything on the view.

Hi
Am having a web page with many textboxes and 3 buttons(button1,button2,button3).
Since there are many textboxes,the user can enter value in them with no tab order,according to his convenience.
My requirement is that -- Wherever the cursor is focussing(any of the textboxes),when the user clicks 'Enter' key,it should activate the Button1's Click event.
Can anyone help me how to do this?
Thanks!

Thanks Deepak
I tried like this...
<br />
function buttonClick()<br />
{<br />
if ((window.event.which == 13) || (window.event.keyCode == 13)) <br />
{<br />
document.getElementById('btnDisplay').click();<br />
return true;<br />
} <br />
else <br />
return false;<br />
}<br />
And in Code behind, i tried as
<br />
HtmlForm form1 = (HtmlForm)Page.FindControl("Form1");<br />
form1.Attributes.Add("onkeydown","javascript:buttonClick()");<br />
Is this correct ?
In which event actually i need to call the Javascript?
Please help me!

You can check by sending a validation email to which the user has to click and confirm. Then you can change the state to 'Active'.
There are some email validation components like ones from Hexillion however not all email servers support the commands used by it.

u can validate the email by regular expession validation
|

|
|
ok sir.. but i want to check the id is in that mailserver database..

You can't do that. If you could, we'd all get a lot more spam

True. That is why VRFY and EXPN commands are disabled by most of the SMTP implementations now.

You can pages not to be cached or expiring.

sir if i work and logout my mail.. and go.. if any one use back button means the pages which i seen are not visible to them...
thank you..

You might not be able to control the visibility of the pages since it is client web browser which has absolute control. However, the following can be taken as workarounds:
1) Page Expiry
2) Application in PopWindow so that you can close the PopWindow after logout.

"An error has occurred writing to the exception log. The permissions are not set properly on the log file or directory, or the log file has been marked as READ-ONLY." why i am getting this and how can I solve this?
