I'm not sure if this is your problem, but deploying your Crystal Reports Viewer in a Web environment requires you to have licenses...

I never understood how exactly the license thing worked (in web environment or windows forms environment, ...), but you can read about it on the internet.

hope this helps...

Coulda, woulda, shoulda doesn't matter if you don't.

Validation for Drop Down list

Hi,

I am trying to validate a drop down list using CustomValidator and even wrote a ClientValidationFunction

 <br />
<asp:CustomValidator id ="ValidateModule1" ControlToValidate = "ddlModule"<br />
ClientValidationFunction = "ValidateModule" text = "Select Module" runat= "server"><br />
  </asp:CustomValidator> <br />
Sub ValidateAuthor(ByVal source As Object, ByVal args As ServerValidateEventArgs)<br />
       If (ddlAuthor.SelectedIndex = 0) Then // means default value<br />
           args.IsValid = False<br />
       Else<br />
             args.IsValid = True<br />
       End If<br />
End Sub<br />

but error message is thrown even when a value other than default value is selected.

I am not able to proceed beyond this

Thanks in advance
Suma

How do you want to validate the dropdownlist? Do you want the user to have to select a new value other than the default one? If this is what you want, then you simply set the value for the default item to empty and simply use the RequiredFieldValidator to validate the dropdownlist.

You might want to double check the schema of the data table before setting the column value for the new row.

I am using external tool for creating menu.
But It allows me to open a URL only on click of that menu.

I want to make visible a table on click of that menu.

How to Do This ?

Can you not just set a javascript call to a function instead of a url?

Something like:

javascript:ShowTable();

and then in that function set the visibility of the table.

Hi,
I have a page that calls a sql procedure and it runs for 20 - 40 min. I use usual threading for this page.

Thread objthread = new Thread(new ThreadStart(ticketingThread));<br />
objthread.Start();

As i dont know when it will end. i never abort the thread. what happens is when user uses the page for 1 weeek, the page starts hanging. I dont know what happens. When i tried debugging it works fine.

I also saw creating thread in threadpools

ThreadPool.QueueUserWorkItem(new WaitCallback(ticketingThread));

Please advise which one i have to follow and what is the difference between the two.

Thanks

Venky

Hi Venky.

I have nothing to hand here, but i remember that you can use a delegate to run the thread, and then a callback function which will terminate it.

Im not sure how often this thread is getting created, but even if it is only once, it is good practice to terminate the thread when it has completed its job.

Cheers

Mark.

I have asp.net page for user login, after login they can sign out before exit page, but if they not click logout, the machine will remember his/her ID?

At the LOGIN save the user id in session e.g Session["UserId"] = userid.Text and on button click of logout clear the Session value. What will happen is if he doesnt press the logout button the value stays stored otherwise it will be cleared.

So u can use this value the next time he/she logs in.

Hope I helped

If only they could see what I see in my mind
