Sorry, but this has "homework assignment" written all over it. We're not going to write your code for you. You wouldn't learn anything that way. Everything you need has already been covered in your class.

A word of advice, the verb to Want is too abrasive to use when you are the one making a request from a position of weakness. It's better to use the subjective, i.e. "would like". Same principal I know applies in Spanish and German and I would expect to be fairly universal. Put simply it's the polite way to make a request of somebody you have no authority over. Not that it'll help you here, mind. Also, for the love of God, use a decent naming system!

sorry, I would be really grateful to you if you could help me. Please don't mind. Help me out, please!
MidwestLimey was correct and you're still not quite getting it. It's not polite to ask for help and then in the same request demand it with an exclamation mark. So lets practice as if you were going to ask for help from Dave, you could try kissing his a$$ a little like: "Dave the almighty who rules next to Xerxes - could you find it in your gracious heart to feel pity upon my disgraced soul and help me with my problem? I am nothing without your assistance and bow before your presence." Or...........you could simply ask for help without it demanding, caps, or !s. Your problem does kind of look like a homework assignment.
Any suggestions, ideas, or 'constructive criticism' are always welcome. "There's no such thing as a stupid question, only stupid people." - Mr. Garrison

If you want help, you have to give more information. What isn't working? What error message are you getting? Show us what code you have so far. We're not going to do your work for you, but if you have a specific problem we can try to point you in the right direction to get help.

objAdapter1.SelectCommand = objCmdSelect
objAdapter1.Fill(objDataSet, "test")
DataGridView1.DataSource = objDataSet.Tables(0).DefaultView
objConn.Close()
End IfI have this and now to replace the data in existing database with that in datagridview I am using:
objAdapter1.Update(Me.dataset.filename)
But its not making any change in dataset table.rest is ok.

If I can not get my work done at my job, then I'll have to face the reality. Shouldn't you?
Yusuf Oh didn't you notice, analogous to square roots, they recently introduced rectangular, circular, and diamond roots to determine the size of the corresponding shapes when given the area. Luc Pattyn[^]

+5 for the wit, -5 for not wanting a little lipstick on the ass.

objAdapter1.Fill(objDataSet, "test")
DataGridView1.DataSource = objDataSet.Tables(0).DefaultView
objConn.Close()After this I wrote:
objAdapter1.Update(Me.Db1DataSet.Sheet1("test"))
Because the dataset that I want to update is in by DB1DataSet.Sheet1. I dont want to update the datagridview itself. I want to update an existing database called DB1DataSet.Sheet1 from the datagridview. when I wrote above line its says following error:
Error 1 Overload resolution failed because no accessible 'Update' can be called with these arguments:
'Public Function Update(dataTable As System.Data.DataTable) As Integer': Value of type 'WindowsApplication1.db1DataSet.Sheet1Row' cannot be converted to 'System.Data.DataTable'.
