Hi ,
I am trying to insert records into database. I am trying
to write the following code.
On button1 click event i am inserting five records and
after that i am calling the update method of dataadapter
to update the records in database.
Records are inserting but all the five records have the
same value and that too of that last ones..
More over i tried to use the acceptchanges methods for
datatable and dataset but of no use
ihave used the following code
Dim da As New OleDb.OleDbData Adapter("select * from
test", "Provider=SQLOL EDB;Data Source=192.168. 16.4;Initial
Catalog=Northwi nd;user id=sa;password= ;")
Dim myConnection As New OleDb.OleDbConn ection
("Provider=SQLO LEDB;Data Source=192.168. 16.4;Initial
Catalog=Northwi nd;user id=sa;password= ;")
Dim dt As DataTable
Dim dr As DataRow
Dim ds As New DataSet()
Private Sub Form1_Load(ByVa l sender As System.Object,
ByVal e As System.EventArg s) Handles MyBase.Load
da.Fill(ds, "test")
End Sub
Private Sub Button1_Click(B yVal sender As
System.Object, ByVal e As System.EventArg s) Handles
Button1.Click
dt = ds.Tables("test ")
da.InsertComman d = New OleDb.OleDbComm and("insert
test values('" + TextBox1.Text + "','" + TextBox2.Text
+ "')", myConnection)
Dim i As Integer
dr = dt.NewRow()
dr("name") = TextBox1.Text
dr("address") = TextBox2.Text
dt.Rows.Add(dr)
MsgBox(dt.Rows. Count())
End Sub
Private Sub Button2_Click(B yVal sender As
System.Object, ByVal e As System.EventArg s) Handles
Button2.Click
Try
da.Update(ds, "test")
MsgBox("Record saved")
Catch er As Exception
MsgBox(er.ToStr ing)
End Try
End Sub

"Hi Pushpendra Vats
I deleted some things and added some things, that commandbuilder is not the
nicest however that insert command you was using also not.
Give it a try?
It is just changed in the text so watch typos or other errors.

Dear Cor,
Thanks a lot fro the solution but i really could not
understand why the same is not working with the
insertcommand.
One more thing if i use the acceptchanges method with
datatablenad dataset still it was not working....
Thanks a lot....again... .

Hi Pushpendra,
Maybe the insert does work also, however why do more work than needed.
The acceptchanges is to prevent updating.
It stands for Accept the changes as if you did the updating.

In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
