i want to convert sql data to Text.txt Format , How it Posible?

First, this question is not related to asp.net.

If you want to convert SQL Server data into text format, you can use export/import feature available in the SQL Server Management Studio.

Hi all!!!
I have a problem wich conversion format DateTime.
I create AjaxCalendar UserControl, an use it in my page, and I have a conversion format DateTime:

<br />
protected void AjaxCalendar_DataBinding(object sender, EventArgs e) {<br />
        try {<br />
            DateTime time = DateTime.Parse(TextDate.Text, new CultureInfo("en-GB"));<br />
        }<br />
        catch (Exception) {<br />
            TextDate.Text = string.Empty;<br />
            return;<br />
        }<br />
}<br />

and asp code of User Control:

<asp:TextBox ID="TextDate" runat="server" Width="70px" />
<Ajax:CalendarExtender ID="AjaxCalendar" runat="server" TargetControlID="TextDate" Format="dd/MM/yyyy" OnLoad="AjaxCalendar_DataBinding"/>

I load from database and add to database datatime from this control. When I use Visual Studio (I use Visual Studio 2008) this conversion work fine, but when i put my project page on IIS or on Server this conversion not work, and i obtain "String.Empty".
If I block this code I obtain data in format MM/dd/yyyy. In Regional Options i have selected format English and stat United Kingdom.
I write implicit conversion in this Mode ...ToString("dd/MM/yyyy") looks fine, but when i wont to add data in database with datetime i obtain error on dateTime.

Help me, PLEASE to create a conversion function or else, for work in IIS, or on Server.

A DATAPOST COMPUTER CENTRE
(K.V Prajapati)

I have a gridview with autogeneratecolumn false.I have bind it with a data table dt.In dt there is a column named as "status" whose data type i bit.that means status can take either 0 or1.in gridview this column shows true or false.
I want to show "Read" and "Unread" for 0,1 respectively.
How can I do???
plz..help...

In GridView1_RowDataBound(),

try this,

if (e.Row.Cells[1].Text == "0")
{
e.Row.Cells[1].Text = "Read";
}

Use the GridView RowDataBound Event Delegate to change the value of one cell.

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)<br />
{<br />
    e.Row.Cells[0].Text = e.Row.Cells[0].Text == "0" ? "Unread" : "Read";<br />
}

Happy Coding...

You can also use case in query at time of retrieving data from database :-
For Example:-
case status when '0' then 'Unread' else 'Read' end as status

Hi all,
i have deployed a site where a i am reading the username using User.Identity.Name.Remove(0, User.Identity.Name.IndexOf("\") + 1) and then validate this username in active directory. if exist proceed. Locally it is working well however when iam deploying iam disabling anonymous and checking only windows integrated security the first time i input the url a username and password is popping.
What i need is not to pop up this message and directly enter the site if validated.
Any sugesstions, thanks

i need use that with my .net project

Can we show the big size[200 MB] Video in the Web Site?. if it , can we show in the embeded control or is there any other control or easy technic for this.

Ofcourse you can! I don't know the length of the video, visitors of your website have to download the 200 MB of video to view the entire video. If the video is long enough to download the 200 Mb while playing you're fine, else the video will stop playing when the buffer is empty and start buffering the next part of the video. You may consider if this is actually what you want, you're going to use loads of bandwith when your website has a lot of visitors.

For embedding, try silverlight! I even managed to create my own video player with silverlight. If I can do it... You can Wink | ;)

.: I love it when a plan comes together :.

This is an around one hour video. what is silverlight, can i get some sample codes or helping links?

Can anybody help me
