The error is "An error occurred creating the form. See Exception.InnerException for details. The error is: Object reference not set to an instance of an object." The code is: Private Sub btneditstudent_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btneditstudent.Click Dim sqlx As OleDbCommand = New OleDbCommand Dim con As New OleDbConnection("Provider = Microsoft.Jet.OLEDB.4.0;" & "Data Source = Decisionmaths.mdb") Dim xyz As String xyz = Mid(lstboxstudents.SelectedItem, 1, 8) sqlx.CommandText = ("SELECT * FROM Student WHERE StudentNumber = " & xyz) sqlx.Connection = con con.Open() Dim rdr As OleDbDataReader = sqlx.ExecuteReader() If rdr.Read = True Then frmviewsdets.txtsnumber.Text = rdr("StudentNumber") frmviewsdets.txtfname.Text = rdr("SFirstName") frmviewsdets.txtsname.Text = rdr("SSurname") frmviewsdets.txttgroup.Text = rdr("TutorGroup") frmviewsdets.txtascore.Text = rdr("ALISScore") frmviewsdets.txtgcsemath.Text = rdr("GCSEMathsGrade") frmviewsdets.txtattend.Text = rdr("Attendance") frmviewsdets.txtclassid.Text = rdr("ClassID") frmviewsdets.txtpword.Text = rdr("SPassword") End If con.Close() frmviewsdets.btndeletesdets.Hide() frmviewsdets.btnaddsdets.Hide() frmviewsdets.btnviewsdets.Hide() frmviewsdets.Show() Me.Hide() End Sub EXTRA INFO IF NEEDED: I am trying to get information to be pulled out of a database and show in text boxes on another form (frmviewsdets). The error occurs when it gets to the line frmviewsdets.txtsnumber.Text = rdr("StudentNumber") and even when a breakpoint is applied there it just moves on to the next and so on. I have tried to show frmviewsdets before I pull the data out of the database beut I get the same message. Any help would be appreciated, thank you!
