Hello A GUI application I wrote with VB.Net 2008 Express works fine on the XPSP3 host I use to develop, but fails starting on a fresh Windows 7 host with the following error: Description: Stopped working Problem signature: Problem Event Name: CLR20r3 Problem Signature net runtime error 01: myapp.exe Problem Signature 02: 1.0.0.0 Problem Signature 03: 4eb2a385 Problem Signature 04: myapp Problem Signature 05: 1.0.0.0 Problem Signature 06: 4eb2a385 Problem Signature 07: f Problem Signature 08: c6 Problem Signature 09: System.InvalidOperationException OS Version: 6.1.7600.2.0.0.256.1 Locale ID: 1033 The Windows 7 has .Net framework 4 by default, so figured maybe the framework isn't downward-compatible, but when I run the .Net 2.0 framework installer (dotnetfx.exe), it says it's already installed. Weird :-/ I also tried running the app as Admin, with no change. Next, I found this thread here, that says to "Try handling the UnhandledException event of your application, which all VB.NET WinForms apps should do. Hopefully it should be able to tell you exactly what's happened.". So following this article, I added a "Private Sub OnThreadException()" and a "Public Sub New" to Form1 thusly: Code: Public Class Form1 Inherits System.Windows.Forms.Form Public Sub New() AddHandler Application.ThreadException, AddressOf OnThreadException InitializeComponent() End Sub Private Sub OnThreadException(ByVal sender As Object, _ ByVal e As ThreadExceptionEventArgs) ' This is where you handle the exception MessageBox.Show(e.Exception.Message) End Sub Next, after a successful build, I downloaded the app on the

After the reset, I installed all of my programmes, including Visual Studio 2013 (I had 2012 on my last build). I then dumped my projects into the projects folder of 2013 and...I COULDN'T RUN MY PROJECT!!! I can view the code and the designer but I can't run it. The error is from Application.Designer.vb and it is a "System.InvalidOperationException" error. Under additional information, it says "An error occured creating the form. See Exception.InnerException for details. The error is: Object reference not set to an instance of an object. Highlighted is Me.MainForm = Global.MyApplicationName.Form1 I have checked msdn for answers about System.InvalidOperationException but haven't found any fixes that work. I really don't know what to do and don't want to lose my application as I've spent a fair bit of time on it. vb.net error-handling runtime-error invalidoperationexception share|improve this question edited Oct 24 '13 at 17:17 Plutonix 29.6k112548 asked Oct 24 '13 at 17:03 Josh-Mason 100215 1 Very obscure, impossible to diagnose from just the exception message. Just restore the last working version of your project from source control. If you don't have any then you've just learned a very valuable lesson. –Hans Passant Oct 24 '13 at 17:30 add a comment| 1 Answer 1 active oldest votes up vote 1 down vote I have 2 suggestions to try Open Application.Designer.vb and just delete the word Global. Exclude (not delete) the mainform (Form1, apparently) from the project. Save it. Then include it again and go to Project Properties and make it the startup form again. I've had similar issues (without the exception) when reorganizing pieces of large solutions into other namespaces. Often, I need to drill into the designers to change a ref to get it to run and it is usually removing 'Global' and/or adding the new Namespace ref. In your case, it sounds like a similar reference in the project did not get updated from 2012. If that is the case, the second way should get VS to write back all
