This stuff is a bit horrid in C#. What you are doing here is declaring a jagged array of type int. That is to say an array of arrays of int.
Now I'm not quite sure why you are getting that particular error - something to do with it assuming you are using an indexer rather than dereferencing an array I guess, but the code is flawed. Having newed up the outer array, you will need to create an inner array for each and every item in the outer array. Confusing stuff, especially if you're from a C++ background. I'd expect you to get null reference exceptions instead. Arrays are references types (of type System.Array) in .NET and must be newed up before use.

Hi
I want to know how it s possible to hide a column in a gridview that s filled by a dataset. I know the property Gridview.Columns[index].Visible but when i put it to "false" i got an exception: ArgumentOutOfRange.
Can someone help me?
THx

Looks like the index value is out the range of the valid values, you might want to double check this value. Another option is to make all the cells of the specified column invisible. You can do that in the RowDataBound/RowCreated events of the GridView control.

Hi,
Actually I want the Data to be displayed in my DataGrid Control in Vertical Form. But i m unalble to. and also i want the Headings of the Columns to be displayed according to my Requirements(user defined) but it is always bounding data with the names of fields i.e. suppose if the field name is: Emp_ID, DataGride is showing the field name but i want Employee ID to be shown.
Is there any way to do this!!!

regarding column header yes..
Atleast 2 ways to do this :
a. You can use an alias name while fetching from the database, like select abc as 'abc efg' from tablename.
2. You can make use of Column mapping

Your sample code tells me that you only add 1 column to the Columns collection of the datagrid. Don't be confused between two columns with two controls in a single column.

I currently hosted a site, and at the time of member registration we get the following 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".

The error is "Could not Access CDO.Message Object".
On each exception I am seding mail to the admin.
This error comes every time when I am trying to send email through code.
I have wrriten code as following.
catch(Exception ex)
{
string MessageBody = "Exception " + ex.GetType.ToString() + " occured on page " + this.ID + " on " + DateTime.Now.ToString();
MailMessage mail = new MailMessage();
SmtpMail.SmtpServer.Insert(0,"66.36.242.151");
mail.From = "chetan@innovault.com";
mail.To = "admin@innovault.com";
mail.Subject = "Error Occured in the system.";
mail.Body = MessageBody;
SmtpMail.Send(mail);
}
Error comes When the Last Line of code executes.
Can u tell me if anything is wrong in my code?
Thank you.

Chetan Ranpariya.

Hi Chetan,
Looking at the error "Could not Access CDO.Message Object", I think there is a problem related to the permissions to relay through the IIS SMTP Service.
To allow access, open up the IIS Admin MMC. Locate the SMTP Virtual Server, and right-click, then select Properties. On the Access tab, click the Relay button. In the Relay Restrictions dialog, grant your IP address
(e.g 127.0.0.1) to the Computers listbox. Close down all dialogs, and restart the SMTP Service.
I got the same problem some time back and used the above procedure. Hope it helps u..
For more details u can check this link

Hi Vaibhav.
Thanks for the reply.
You are right vaibhav.
I have tried that. That works on my system very well.
But when I uploaded my site on the server and tried to test it, it gives me error.
For example you open www.innovault.com and try to make your login there.
Your login will be created successfully but you will get error page with error "Could not Access CDO.Message Object" as well.
This error comes when system tries to send u a mail informing that your account has been created including your username and password.
Is there any thing to setup from my mailserver or something else?
Plz reply me soont its very urgent.
Thank you very much.
Regards,
Chetan

Have you copied the web.config file? If not please copy that and try again. This error may also occur when a required file is missing.

Hi,
I have a form with the following format:
a the the top there are two buttons, followed by a text field, followed by a submit button. When I load the page, and press enter, nothing happens. When i select the text box and type stuff and press enter, the first button gets selected. The problem is this is a logout button. By default I want the submit button to be selected. I tried tabindex=1 on it but that didnt work. Any ideas? Thanks in advance,

Hi,
I would like to use .net passport with an asp.net application. I have installed the passport SDK.
I came across a website that said that after installing the SDK, the developer has to create an application in the .NET Services Manager.
In other words, the developer must submit the application information to Microsoft using the Microsoft .NET Services Manager. This allows the ASP.NET application to access the Microsoft Passport servers. Particulars about the application has to be entered.
Is it possible to have .net passport functionality done locally, instead of using Microsoft's Passport servers?
All I need is just a .net passport user account which can access 2 different websites.
The page explaining passport can be found here:
http://www.builderau.com.au/program/windows/soa/Integrate_Passport_into_ASP_NET_apps/0,39024644,20273635-1,00.htm
