hey guys thanks for all your replies
i use MsSql 2008 express..and i tried something like that
try
{
dr[j] = xnl.Item(i).ChildNodes[j].InnerText;
}
catch(SqlException ex)
{
Console.WriteLine("This Record is already exist");
}
but still on the screen it shows the same error which is shown in Sql screen
and sometimes it gives error like object reference not set to an instance of an object in that line
dr[j] = xnl.Item(i).ChildNodes[j].InnerText;
what is wrong here.i read a Xml file over website and put it in a datatable is it because it cannot connect that site ?

In this case, I'd suspect that xml.Item(i) doesn't have any child nodes, so attempting to do anything with it would cause a problem.

I think exception try..catch.. can only save you from this trouble.
Just use Try and Catch SqlException.
And check the detail in SqlException,If it Contains word 'UNIQUE' then you'll get sure that the exception is regarding UNIQUE Key Constrain and further more you can notify to users with a formatted message.
That's not a big deal.

And what do you do when you deploy it onto a localised version of SQL Server, say the Japanese version?

Hi,
how to change (override) selected (highlighted)listviewitem background color in listview control.
|
|
|
|

Subclass the control and handle the OnPaint method. Or use WPF and apply a template.

You could use THIS[^] for complete information about parsing PDF file.
Underneath that page you will find one link which will redirect to our own Codeproject article and that is THIS[^].
Hope this will make you clear about your doubt regarding PDF parsing.

Dear Friends,
I need to add a customized DateTime picker control onto my webpage. As in my database table; the data is being stored in the following format:- "yyyy-mm-dd hh:mm:ss.mmm" so the user needs to select the date and time in the following format only in order to get the correct data from the database.
But I am not able to make such control. Could anyone help me out, how should i proceed with making this control?

As far as I understand your question, You don't need to make such a custom control to display value in format you want. there's inbuilt property in DateTime Picker control of Custom format you can set custom format as you want accordingly.
See this MSDN[^] Article for more detail.
Regards,
Hiren.

You should never store a date, a time or a datetime as a string if there are alternatives. Most databases do have some kind of date or datetime field type, so use it. A database cares about storing data, not formatting it; your app must deal with formatting data when presented to the user.
This[^] little article may tell you more about datetime type.

I have two pieces of advice for you:
1.
I would suggest you select, buy and study an introductory book on C#. You have been asking a number of pretty elementary questions lately, reading a book would teach you much more in a shorter time. Visit a book store (if none around, look at Amazon), and get to it.
2.
Learn to help yourself, use Google and MSDN. Operations on files are most likely handled by the File class. Maybe WriteAllText() is your friend. Look them up, read about it, and try.

Good advice.

The formats supported by the Image class are listed here[^].
Simply change your OpenFileDialog Filter to include those you are interested in.

i tried changing.i have a index error. can you give me a particular sytax

You currently have:
openFileDialog1.Filter = "All Image Files|*.bmp;*.ico;*.cur|All files (*.*)|*.*";
To add a filter for PNG files (for example) simply add the filename template between 'cur' and the '|' before 'All Files', not forgetting to separate it by a semi-colon.
openFileDialog1.Filter = "All Image Files|*.bmp;*.ico;*.cur<sup><big>;*.png</big></sup>|All files (*.*)|*.*";
I have tried to make my additions stand out by superscripting it.
Have a go with the others yourself.
