"Object reference not set to an instance of an object" when opening designer

I have a Windows Forms project which was originally developed in Visual Studio 2010. I migrated the project to VS2013, and now every time I open the project's main form, the designer complains of a null reference. If I hit "Ignore and Continue",
the code compiles just fine. The error in question appears in the "Windows Form Designer generated code" region. Even more curious, the line in question is not the first reference to the object. It's as if the first few times it needs to interact
with the object, it's fine, then at a certain point it becomes null.
Here is the call stack for the error:
at System.ComponentModel.ReflectPropertyDescriptor.SetValue(Object component,
Object value)at
Microsoft.VisualStudio.Shell.Design.VsTargetFrameworkPropertyDescriptor.SetValue(Object
component, Object value)at
System.ComponentModel.Design.Serialization.CodeDomSerializerBase.DeserializePropertyAssignStatement(IDesignerSerializationManager
manager, CodeAssignStatement statement, CodePropertyReferenceExpression
propertyReferenceEx, Boolean reportError)at
System.ComponentModel.Design.Serialization.CodeDomSerializerBase.DeserializeAssignStatement(IDesignerSerializationManager
manager, CodeAssignStatement statement)at
System.ComponentModel.Design.Serialization.CodeDomSerializerBase.DeserializeStatement(IDesignerSerializationManager
manager, CodeStatement statement) 
And here is the code in question:
this.optionsControl.Anchor = ((System.Windows.Forms.AnchorStyles)((((System.Windows.Forms.AnchorStyles.Top | System.Windows.Forms.AnchorStyles.Bottom) | System.Windows.Forms.AnchorStyles.Left) | System.Windows.Forms.AnchorStyles.Right))); 
this.optionsControl.IsAsciiMode = false;           
this.optionsControl.Location = new System.Drawing.Point(3, 3);
this.optionsControl.LogControl = null;           
this.optionsControl.Name = "optionsControl";           
this.optionsControl.PlugInManager = null;           
this.optionsControl.PortFacade = null;           
this.optionsControl.Size = new System.Drawing.Size(613, 259);
this.optionsControl.TabIndex = 0;
The problem is reported at the third line, "this.optionsControl.Location = new System.Drawing.Point(3, 3);".

Hi Eric,
I have made a research about your issue, and I found it might be caused by the usercontrol in the project. Was “this.optionsControl” a UserControl? It seems that this issue was difficult to handle.
If possible, I would recommend you recreate this control in a new project.
In addition, I think you could turn to the links below, they may be useful to you:

  • "cacheHostInfo is null" and Add-SPDistributedCacheServiceInstance : Object reference not set to an instance of an object.

    I am working on a standalone install Sharepoint 2013 (no Active Directory). I found newsfeed feature is not available and checked Distributed Cache service is stopped. When start it “cacheHostInfo is null” is returned.
    I checked the Windows service “AppFabric caching service” is stopped because the default identity “Network Service” not work. Then I change the AppFabric service identity to use “.\administrator” (which is also the sp farm administrator) and the service can
    be started.
    However the “cacheHostInfo is null” when try to start Distributed Cache service in central admin.
    I searched on web and found this blog: http://rakatechblog.wordpress.com/2013/02/04/sharepoint-2013-spdistributedcacheserviceinstance-cachehostinfo-is-null/

  • "An error has occurred:Object reference not set to an instance of an object."

    This error message comes up with a user in InfoView.  The user schedules a report, updates parameters, and the report kicks off successfully.  But then a few minutes later, this error is received.    This occurs sporadically, regardless of the length of time of report or amount of data being retrieved.  Sometimes the report runs to completion.  Other times this error message occurs.
    Has anyone seen this before and have any thoughts?
    Thank you.
    “An error has occurred:Object reference not set to an instance of an object.”

    Are you able to replicate the issue both in Java and .NET InfoView?
    For .NET InfoView, sometimes the "An error has occurred: Object reference not set to an instance of an object" error shows up after the .NET Framework is upgraded to 2.0

  • "object reference not set to an instance of an object" error while running ssrs report locally

    Hi Folks,
    I am a bit new to SSRS.
    I am using ssrs 2012 and trying to use a method from a dll file. I am loaded the assembly file in reference of the report.
    Now I am trying to use a static method from the Dll. e.g. applicationName.classname.MethodName()
    But while running the report I am getting "object reference not set to an instance of an object" error.
    For a note I am trying execute the report locally.
    Any help would be highly appreciable.
    sarat chandra sahoo

    Sorry for late reply Sinaloe..
    I have added a dll file in my report reference. And in a textbox trying to execute this below.
    =Recall.Common.LocalizationEx.Localization.GetString(Parameters!Culture.Value, "RFID", "BICustomerPortal")
    where Getstring() is a static method in the dll.
    I guess some configuration setting I am missing here.
    1. I have copied these dlls in "C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE\PrivateAssemblies" and "C:\Windows\Assembly".

  • "Object reference not set to an instance of an object" when I try to deploy my Azure Cloud Service via CLI

    I have added my certificate and verified it with Get-AzureSubscription.
    Can anyone help?

    When I run Get-AzureSubscription, the subscription already seems to be set. I assume this happened when I imported my publish settings. I tried your suggestion to do it manually, but this didn't fix my problem.
    I've started implementing the deployment script linked in the blog post, but I'm running into all sorts of problems as I try to do so. First, this seems to assume I have a service package and publish settings. I'm guessing the package is going to need to
    be generated for each deployment, but the script doesn't handle this. How can I also have the script generate the new package so that the service can be deployed? I've currently hard-coded the path of cspack into the script, but this seems like a bad way to
    do it.
    Since the publish settings have the certificate, I imagine I don't want to commit those to version control. Can I also generate this as part of the script? I want the script to be as hands-off as possible.
    Thank you for your help!

  • "Object reference not set to an instance of an object" after view selection

    Hello,
    I have a Visual Studio LightSwitch project where I connect to a Oracle server and select a view as a new data source.
    I get a error message "Object reference not set to an instance of an object" after selecting the Oracle view as a data source.
    The Visual Studio Log shows me following details in the ActivityLog:
    362 End package load [Visual Studio Explorers and Designers Package] {8D8529D3-625D-4496-8354-3DAD630ECC1B} VisualStudio 2011/09/05 12:17:58.258

    But this error ORA-12560 does not make any sense, because I have got a working connection to the Oracle server and can see tables and views.
    Any ideas?
    Environment:
    Visual Studio 2010 SP 1
    Windows Server 2008 R2
    ODAC 11.2.0.2.40 Beta 2 for Entity Framework and LINQ to Entities

    Hi, did you ever resolve this? I have the same problem.

  • Object reference not set to an instance of an object in treeView

    Hello
    I wrote this code. I have this Error "Object reference not set to an instance of an object" on  " MessageBox.Show(tn.Text);"
    in " MaintreeView_BeforeSelect ".
    #region Remove BackColor of all treeview nodes
    private void ClearBackColor()
    TreeNodeCollection nodes = MaintreeView.Nodes;
    foreach (TreeNode tn in nodes)
    ClearRecursive(tn);
    private void ClearRecursive(TreeNode treeNode)
    foreach (TreeNode tn in treeNode.Nodes)
    tn.BackColor = Color.Empty;
    if(tn.IsSelected == true)
    tn.TreeView.SelectedNode = null;
    ClearRecursive(tn);
    #endregion
    private void MaintreeView_BeforeSelect(object sender, TreeViewCancelEventArgs e)
    ClearBackColor();
    TreeNode tn = MaintreeView.SelectedNode;
    if (tn != null)
    MessageBox.Show(tn.Text);
    if (tn.Level == 7)

    Hi ARZARE,
    I tested your code, it can show the tn.Text when in the rootnode.
    I suggest you putting the ClearBackColor() at the last of the BeforeSelect Event. Or this method will clear the selectNode.
    private void treeView1_BeforeSelect(object sender, TreeViewCancelEventArgs e)
    //ClearBackColor();
    TreeNode tn = this.treeView1.SelectedNode;
    if (tn != null)
    MessageBox.Show(tn.Text);
    ClearBackColor();
    If you have any other concern regarding this issue, please feel free to let me know.
    Best regards,

    Hi,
    This is a general error message. I would ask the following questions to verify the issue:
    1. Are these charts  inside the table?
    2. Does the table display fine? What’s the size of the report and charts?
    Please try download the latest cumulative update package for SQL Server 2008 R2 Service Pack 2 from the following link and see if it address the issue:
    http://support.microsoft.com/kb/2730301/en-us
    You can also capture the screenshots regarding the issue so that I can understand
    problem in more details.
    Thanks.

  • Object reference not set to an instance of an object. Unable to finish the SQL 2012 installation on a VM Machine

    Hi, My name is Leonard and I am studying SQL. I have downloaded the newest MS SQL 2012 and also MS 2012 Hyper-V. I have set a MS 2012 Hyper-V on a laptop with AMD Turion 64 X2 and 3G of RAM (Planing
    to add more to max at 8G).
    Following the instructions in the free online
    Administering Microsoft SQL Server 2012 Databases” Training Kit, I have set 6 virtual machines as instructed in the Training Kit. While the installation of the MS Server Core 2008 R2 SP1 completed with no
    problem, the same cannot be said for the SQL Server 2012 installation. I have encountered an error that I have not seen anyone address in any of the SQL web forums.
    After running the unattended setup instruction (Setup.exe /qs /ACTION=Install /FEATURES=SQLEngine /INSTANCENAME=MSSQLSERVER
    /SQLSVCACCOUNT="Njowa\Pa$$worD>" /SQLSVCPASSWORD=" Pa$$worD” /SQLSYSADMINACCOUNTS="Njowa\lenny#[email protected]" /AGTSVCACCOUNT="NT AUTHORITY\Network Service"
     /IACCEPTSQLSERVERLICENSETERMS) this is what I get after a series SQL setup
     initiation windows popups then disappears.
    The following error occurred:
    Object reference not set to an instance of an object.
    Error result: -2147467261
    Result facility Code: 0
    Result error Code: 16387
    Please review the summary.txt log for further details
    My question is: What instance of an object is not properly initialize in the Setup instructions

    Hello,
    Please note that SQL Server requires at least 1 GB of RAM. The operating system (Windows Server) requires 2 GB of RAM (recommended) or 512 MB (minimum). This means any virtual machine that will receive the installation of a SQL Server instance requires 1.5
    or 2 GB at least.
    The behavior of SQL Server setup tells me that the virtual machine does not have enough memory assigned or .NET Framework 3.5 was not enable on Control Panel->Program
    and Features before trying to install SQL Server.
    The following thread is about another possible cause of this error:
    http://social.msdn.microsoft.com/Forums/mr-IN/sqlsetupandupgrade/thread/575d3025-69f5-4152-a473-44496b008811
    Hope this helps.
