Please remove all the irrelevant code from your question. –Konrad Rudolph May 19 '10 at 15:19 1 As soon as I debug, the whole point in this question was to see where the error was, so it could be anywhere - hence posting it all. –Ben May 19 '10 at 15:22 No … the error cannot be in any of the Buttonx_Click events, now can it? –Konrad Rudolph May 19 '10 at 15:24 add a comment| 3 Answers 3 active oldest votes up vote 3 down vote accepted The error is here: Dim textz As String = TextBox1.Text and here: Dim NewArray() As String = TextBox1.Text.Split(vbNewLine) and possibly here: Dim sections() As String = Text.Split(sep, StringSplitOptions.None) You cannot initialize a member like this because this code is basically executed in the constructor, before TextBox1 (or any other control

The error is: Object reference not set to an instance of an error occurred 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 an error occurred 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 29.5k112548 asked Mar 5 '15 at 21:25 Kristina 11 I doubt that is the correct line - button click event do not normally happen while creating the form. You could compile for AnyCPU and run it in the IDE and likely get a better idea where it is –Plutonix Mar 5 '15 at 21:37 @Plutonix That's the line the debug pointed me to with Any CPU setting –Kristina Mar 5 '15 at 23:00 Well the error says something bad happened while creating the form; the line you indicate exists in a button click event. So the question is how did that ev
