The error is: Object reference not set to an instance of an object up vote 0 down vote favorite When running my VB.Net code (below), I get the following error: An unhandled exception of type 'System.InvalidOperationException' occurred in CropModel.exe An error occurred creating the form. See Exception.InnerException for details. The error is: Object reference not set to an instance of an object. Private Class Frm_Main Private Sub Form_MainControl_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Me.Reinsurance_YearTableAdapter.Fill(Me.CUNACropModelDataSet.Reinsurance_Year) Me.Ref_CropTableAdapter.Fill(Me.CUNACropModelDataSet.ref_Crop) Me.MdiParent = MDIParent1 End Sub Private Sub Button_ModelLoss_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button_ModelLoss.Click Frm_LossModel_Select.MdiParent = MDIParent1 Frm_LossModel_Select.Show() Frm_LossModel_Select.Activate() 'Me.Close() End Sub End Class The debug points the issue in the following line: Frm_LossModel_Select.MdiParent = MDIParent1 Seems this error is very general. Is it possible to know where the actual error is being caused in Frm_LossModel_Select (if it is even being caused there)? The only things changed in that form were DataSet names and table names from SQL and I made sure those were all being referenced properly. If additional code is needed for this issue, I'd be more than willing to provide. Thanks! vb.net share|improve this question edited Mar 5 '15 at 21:34 Plutonix 29.4k112548 asked Mar 5 '15 at 21:25 Kri

Posted 11 March 2010 - 09:52 AM Hello, I'm posting here about this general problem because I've been struggling on this for well over 24 hours now and I'm completely lost as to what I need to an error do to fix this. Here's my situation. I have created a class which creates a system timer and execute code when it ticks. Public Class Timer Friend WithEvents Action As New System.Timers.Timer Public lviAction As ListViewItem Private Sub Action_Tick(ByVal sender As Object, ByVal e As EventArgs) Handles Action.Elapsed frmMain.ncMain.BalloonTipTitle = lviAction.Group.Header frmMain.ncMain.BalloonTipText = lviAction.Text & " > an error occurred " & lviAction.SubItems.Item(0).Text frmMain.lvActions.Items.Item(lviAction.Index).Remove() End Sub Public Sub StartTimer(ByVal lInterval As Long) Action.Interval = lInterval Action.AutoReset = False Action.Start() End Sub End Class In my main form, I have the following code to that creates the timer: Private Sub Level1ToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Level1ToolStripMenuItem.Click If DialogInterval.ShowDialog = Windows.Forms.DialogResult.OK Then 'Add a new item in the listview for the new action Dim NewAction As New ListViewItem NewAction.Text = "Bank Management" NewAction.Group = lvActions.Groups(0) NewAction.SubItems.Add("Level 1") NewAction.SubItems.Add(ActionDateTime) lvActions.Items.Add(NewAction) 'Create a new timer for the new action Dim Action As New Timer '(My class timer) Action.lviAction = NewAction Action.StartTimer(TimerInterval) End If End Sub I'm getting the following error when the timer tick: System.InvalidOperationException was unhandled by user code Message="An error occurred creating the form. See Exception.InnerException for details.

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!
