any one can help me....

Show the full error message.

What database are you using?

For debugging, create your query in a variable so you can output it to check for errors.

the error like this

Syntax error in INSERT INTO statement.

I'm using MsAcess datbase

Put your query in a variable so you can display it, and then post it here. Without the query there's no telling what the error is.

i'm a beginer i dont'know how to do that can u help me?

Here is my full coding...

Try this :

Dim com1 As New OleDb.OleDbCommand
com1 = con1.CreateCommand
com1.CommandText = "insert into Department(DNo,DName,Manager,AddressL1,AddressL2,City,Telephone,E-mail)values('" + TextBox1.Text + "','" + TextBox2.Text + "','" + TextBox3.Text + "','" + TextBox4.Text + "','" + TextBox5.Text + "','" + TextBox6.Text + "','" + TextBox7.Text + "','" + TextBox8.Text + "' )"

what about the
com1.ExecuteNonQuery() is it want?

i tryed that but again same result

Dim qry As String = "insert into Department(DNo,DName,Manager,AddressL1,AddressL2,City,Telephone,E-mail)values('" + TextBox1.Text + "','" + TextBox2.Text + "','" + TextBox3.Text + "','" + TextBox4.Text + "','" + TextBox5.Text + "','" + TextBox6.Text + "','" + TextBox7.Text + "','" + TextBox8.Text + "' )"
Debug.WriteLine(qry)

Then copy the output and post it here. In any case, you should be using parameterized queries. See examples here

I tried the code with SQL Server and it worked fine. I think that there is a different way to connect it with MSAccess.
