It is not really easy to tell that what questions will be asked in the interview. This completely depends on the person who is taking the interview. You can get some idea if you know that what kind applications that organization is building. Normally you can expect questions on the basic concepts of oops and their implementation and other stuffs. Besides they also give you some scenario and ask you to give your opinion on it. This is just to know your approach on the problem.

Don't use outdated terms like DTS. The current tool would be SSIS. If you don't plan on using entity framework in your sample or something else other than straight ADO.Net in the page, make sure you let them know that a real application would probably use some framework like nHibernate in a real data access layer and not just simple ADO.Net directly in the pages themselves.
Unless of course you personally would normally use ADO.Net directly in the pages. If so, slap yourself with a trout hourly until you learn all about separation of concerns and proper object oriented design.

Hi guys,
Iam trying to update a nullable datetime field in my database using linq-sql.
What ever casting method i have tried i keep getting an error:
"Specified cast is not valid."
Does anyone know how to update a nullable DateTime? field using Linq-Sql? please help me.
I have tried:
myVar.dateredeemed = DateTime.Parse("2010-12-03");
myVar.dateredeemed = (DateTime?)dateTime;
myVar.dateredeemed = DateTime.Now;
I don't really what else i can try because all of the above won't work.
Please help me...

None of this screams LINQ-to-SQL. Your code should work is myVar.dateredeemed is of type DateTime? if not, that is the source of your problem.
This code works:
DateTime? foo;
foo = DateTime.Now;
However, you should be wary of this:
myVar.dateredeemed = DateTime.Parse("2010-12-03")
For two reasons:
- If the string really comes from user input, they can enter an incorrect value you need to decide whether this should be null or whether the user *must* enter a valid date. Whichever is the correct strategy, incorrect input will throw an error.
- Can the user enter no date, (i.e. "")? If so you code will not result in null
Finally, I'd say one more thing: If you have luxury of changing the database, avoid nulls (especially in databases) like the plague. You end up with problems similar to the one you have here, potential null reference exceptions, and they make coding SQL harder too. That's not to say don't ever use nulls, but you should think several times before using nullable columns. Personally, I'd use one of the SQL min/max dates in place of null to register "unknown", (a bit like replacing and unknown [null] string with "") but others will disagree. A null date (to represent a date not set yet) is one of the few places I think a null column might be pukka. </rant> - Sorry I didn't mean to go on like this .

Hai all,
I need to upload file to server and i am using input file to upload the file, my problem is postedfile.filename is always null.
I have tried using updatepanel and had same problem. Can anyone help me.

File upload doesn't work under UpdatePanel ByDefault. you need to set PostBackTrigger in <Triggers> Section of UpdatePanel by which you can force a complete PostBack .

Make sure you are using it under !Page.IsPostBack Condition.

Actually in my form i had a ultrawebgrid and a template column as button,
when click the button by client side the value ll be assign to the fileupload control and
when i click the upload button the file should be uploaded .
My ultrawebgrid and upload button is inside refresh panel and fileupload is outside the refreshpanel.

You can't assign the filename in an upload control with javascript. That is a security feature. Otherwise a web site could tell the browser to upload things like password files and steal data.

He's probably not asking of assigning values rather He wants value inside.

You might want to take a look at what exactly you are doing in your Page_Load event...you could be reseting the values
of your controls...
Put the code above in a method e.g.:
protected void Page_Load(object sender, EventArgs e)
{
if(!IsPostBack)
{
UploadFile();
}
}
protected void UploadFile()
{
}

Hi! I recomend you to use Uploadify control of jQuery! Is the easy and best upload control! for multiple or single, max capacity, type of files, queue files in progress, multi browser, etc! Here[^]

please help me.
in javascript, how will I get the total if i have quantity * price.
example:
var quantiy =2
var price = 5,000
var total =parseInt(quantity.value) * parseFloat(price.value)
why is it above total returns 10 not 10,000.
and if I will remove the parseInt and parseFloat it returns NaN.

Your code contains couple of errors. Probably you should start JavaScript from beginning. Check the working code.
<SCRIPT language="JavaScript">
<!--
function tot()
{
var quantity =2;
var price = 5000;
var total = parseInt(quantity) * parseFloat(price);
alert(total);
}
</SCRIPT>
Please use appropriate forums to post questions. You should have posted this in Javascript forum.
