May i know what is the code to automatically send the current time or date to database once i click the button? Since i'm using:
Label11.Text = System.DateTime.Today
Label12.Text = TimeString

Basically at first Data From DB comes to page then after that Textbox data should get appended to the Gridview but Db should not get updated. i tried to do it by keeping DataView in ViewState or Session variable but later i came to know am going in a wrong way and that this won't work since Dataview can't be Serialized. i just need an idea or right path to do this, is this possible what am doing?

I am a high school student and i am teaching myself VB, C# and C++... it is a slow process containing mainly trial and error, looking up things online, and when the time is right asking assistance from people who know more then I.
I am currently creating a VB program that creates a database of questions, and the same or separate database. using them questions it can initiate a quiz that will save results in a different database for each student. I am having difficulties getting the code right for reading the databases, and getting it to move to the next portion of the database for each question... a little more info:
Question # = Primary key (there will not be more then 1 of the same # problem)
Question Type = i am using different integers right now to specify if the question is a T/F, Multiple Choice, Open info Et Cetra.... Question Answer = Correct answer Alt answer (x3) = option to add other answers for multiple choice problems...
I don't know exactly how to get it to read a problem and when clicking a next button on a form to have it go to the next question in the database..
Is it possible to have a quick and easy way of retrieving the last 10 records from a table?

I am using this code at the last line of my form load. I want the position 5,5 to have the cursor set at it. It works when then datagrid is already open:[code]However, when I use it on the form load, you can see that it was selected on the datagrid, but the cursor is set at textbox1...which happens to have the first tab order on the form, even though I have acceptstabs off. Can anyone tell me why this would happen? Basically, it is setting the cursor at the cell I want, but after the form loads, it jumps to textbox1 and highlights the text.
