hello friends,
i am using excel report in asp.net. my excel report is working fine when run within cs file. when publish the project to run on iis the show error. object refrance not set.

That means something you assumed would never be null, is null. Perhaps because Excel is not on the server ? I am obviously guessing, no-one could actually pinpoint the error without seeing the code that is throwing the exception.

Server Error in '/WebSetup4' Application.
Runtime Error
Description: An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine.
Details: To enable the details of this specific error message to be viewable on remote machines, please create a <customErrors> tag within a "web.config" configuration file located in the root directory of the current web application. This <customErrors> tag should then have its "mode" attribute set to "Off".
<configuration>
<system.web>
<customErrors mode="Off"/>
</system.web>
</configuration>
Notes: The current error page you are seeing can be replaced by a custom error page by modifying the "defaultRedirect" attribute of the application's <customErrors> configuration tag to point to a custom error page URL.
<configuration>
<system.web>
<customErrors mode="RemoteOnly" defaultRedirect="mycustompage.htm"/>
</system.web>
</configuration>
Anyone having any idea ???

As the error messsage is saying there is error in the application
to see the specific error make the custom Error mode off in web.config
<customErrors mode="Off"/>
Thanks and Regards

You should write a javascript function which will control the scrolling of the content![Rose | [Rose]](https://codeproject.global.ssl.fastly.net/script/Forums/Images/rose.gif)

From the documentation of the SmtpClient class:
If there is an e-mail transmission in progress and you call SendAsync or Send again, you will receive an InvalidOperationException.
Does that mean users can't send mail (from different threads) at the same time?
Also is there any way to get notified 'programmatically' when the mail is delivered?
Thanks

SendAsyc has an event that fires when it has sent. It's not very reliable, you can't know it was delivered, only that it was sent.

Thanks a lot for your reply, actually I know about this event but I was hoping there's a more reliable way, basically what I'm trying to do is automate the whole process, this is why I don't want to use DeliveryOptions because I don't want to keep checking my email every now and then to make sure every message was sent, doesn't seem a very reliable way in a production environment. It seems that there's no way to communicate with the SMTP server, I wonder how all those websites with high traffic handle mail issues ..

No, there is literally no way to know if a mail got sent correctly, your best bet is to write a program that checks mail on the return address to see if you get a failure notice, but even that won't really work.

Hi
I have used the following tutorial to create an autocomplete extender.
The problem is, it is not working. When I type text in the box nothing happens.
Is there something missing from the exampl code I have used.
I'm not sure where the string value gets filled which is shown in the tuturial.
Any help would be great
thanks!

I think problem is in webservice.I had case like you and when I added third line (of lines down below) it worked.
Try this:
[WebService(Namespace = "http://tempuri.org/")]<br />
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]<br />
[System.Web.Script.Services.ScriptService]

Thanks for the reply, but that didnt work.
Below is my code for extender control
<asp:textbox id="tb_description" runat="server" xmlns:asp="#unknown">
<atlas:autocompleteextender id="AutoCompleteExtender1" minimumprefixlength="1" runat="server" xmlns:atlas="#unknown">
<atlas:autocompleteproperties targetcontrolid="tb_description" servicemethod="GetactdescInfo" servicepath="~/autocomplete.asmx" enabled="True">
Is there anything wrong with that?

this work for me and I am using in VS.NET 2005
<asp:ScriptManager id="ScriptManager1" runat="server"><br />
</asp:ScriptManager><br />
<cc1:AutoCompleteExtender ID="AutoCompleteExtender1" runat="server" TargetControlID="txtTo"<br />
ServicePath="WebService.asmx" Enabled="true" MinimumPrefixLength="1" ServiceMethod="MethodNameFromWebService"><br />
</cc1:AutoCompleteExtender>

string sql = " SELECT description" +

//string description_condition = " AND description LIKE '%" + prefixText + "%'";
//sql += description_condition;
SqlDataAdapter dataAdapter1 = new SqlDataAdapter(sql, connectionString);
dataAdapter1.SelectCommand.Parameters.Add("@prefixText", SqlDbType.NVarChar, 2000).Value = prefixText + "%";
DataTable datatable1 = new DataTable();
dataAdapter1.Fill(datatable1);
string[] items = new string[datatable1.Rows.Count];
int i = 0;
