You recreate the radiobuttons in the onclick event of the button.
after that event has ended your radiobuttons do not exist anymore.

You should state in the beginning of the class (not the event)
RadioButton rb_1;

Then all methods and events refer to the same radiobuttons.

The updates are according to UTC timing.

If you will compare :

It is saying 11:00 in place of 4:30. Means there is exact difference of
5:30 Hrs. This is still accurate if you are doing updates according to IST (UTC + 5:30). UTC was formerly known as Greenwich mean time (GMT).

I Hope I answered your question. Smile | :)

Thanks

Hi Ashu

I got this thing,but i m not asking about why this difference,I m asking about how this difference is there.

My database is on same server where my application code reside,if that server is using GMT+5:30 then why its save in database in UTC.its save that date automatically so is there any way to update this date format for database.

N!dh! Smile | :)

So you need to look at what the default for the column is. Assuming SQL Server, getdate() will give you the local date and time.

Have you return any special code for handling the Login operation? I believe the control itself doing that. It uses its one provider which stores the data in UTC timing. You just use CultureInfo to convert to the local timing.

I'm trying to get data bound to a dropdownlist, however, when the page is displayed System.Data.DataRowView is being displayed within the drop downlist rather than the result of the SQL query.

Any ideas?

<td>
                <asp:DropDownList ID="lstPriority" runat="server" Enabled="False" DataSourceID="SqlDataSource2">
                    <asp:ListItem>Low</asp:ListItem>
                    <asp:ListItem>Medium</asp:ListItem>
                    <asp:ListItem>High</asp:ListItem>
                </asp:DropDownList><asp:SqlDataSource ID="SqlDataSource2" runat="server" ConnectionString="<%$ ConnectionStrings:connString %>"
                    SelectCommand="SELECT [priority]&#13;&#10;  FROM [teamwiki].[dbo].[task_priority_L]"></asp:SqlDataSource>

I want to download one folder containing files from remote server to local computer. i am using vb.net. how should i do it? i have two possible ideas
1. Make zip file, down load to local machine and unzip
2. download files one by one using binary stream.
which one is perfect. if there is any other way?
Please Help

2nd idea will work perfectly, Since for implementing 1st one you need to create zip file on server. That itself is quite tedious. If you are having long haul of time then think about 1st one, other wise implement 2nd approach with the help of starter tutorial from : Downloading Files with the WebRequest and WebResponse Classes[^]

We faced the similar scenario.

The problem was solved as:

1. We created a server application that open a Socket on a particular port of Sever.
2. When client machine need to send data to sever, it converts file to stream, connect to remote socket and transfer data. Finally closes socket connection.

3. Server side control, when receive data from client, it converts stream back to file and save it on disk.

Our transfer was of single file type, so we do not require and special tokens to be passed to identify file type.

Your Requirement :

Functional requirement is to upload a file from remote machine(Client Machine) Without using fileupload control.

It is quite clear that you want to get the file from remote machine (Client Machine). But where do you want to upload the file.

Please correct me I am wrong Smile | :)
