Solution 1

Firstly
Although Today.Date works, I think it is more normal to get Date.Today
secondly, you are trying to pass a VB.net Date object into the DB, which i don't know what type of db etc, you are using, so you will need to look at the suitable methods to convert to db DateTime.

The easiest thing to do is may just to pass in a string representation of the date to the db, and let it take care of things, also unless you need the variable else where, just bin it and work directly;

VB

drNewRowMCQsAns.item("DTE") = Date.Today.ToShortDateString

Depending also on the type of DB you are using, you may have to append a set of #'s to the string e.g.

VB

drNewRowMCQsAns.item("DTE") = "#" & Date.Today.ToShortDateString & "#"

Give that a go and see how you get on.

The proper way would be to use parameter based queries as per the example in this post;

Thanks for the answers but nothing worked!
I tried it by changing the type of filed in database, from DateTime to nvchar
this worked..... But I want to save it as date not as string.
Any suggestions?

Don't change the database, thats the type you are wanting. Think you need to update your original question with the code snippet you are using and tell type of db you are using etc.

I am using SSCE database. The code is what I already entered.
One thing I noticed, If if save the value of a datetimepicker, there is no error.
That means that is compatible type of data. But when I try today.date, then I get problem.

DaveAuld 14-Aug-11 15:03pm

DateTimePicker.Value returns a DateTime, hence the reason it probably works. Have you tried to drNewRowMCQsAns.item("DTE") = ctype(Date.today, System.DateTime), although there is no reason why the string method with the #'s shouldn't work.
