I am new to visual studio 2013 vb.net
I am getting this error message when I open any class in my project.
Can anyone explain what this means and maybe a possible fix?
Thanks!
Microsoft Visual Studio

Reinstall Visual Studio. Keep the projects and start fresh.
I want to open a program (written in Visual basic 6) to be open in Visual Studio.net. Please guide, how could I do that?
While trying to open VB6 (.vbp file) program directly from the OPEN project option in visual studion.net, I was getting this error,
"Visual Basic 6 (.vbp) files cannot be opened in Visual Studio"
I am trying to open in VS 2010.
Visual Studio 2010 does not support VB6 projects. See the link here
From the msdn documentation:
Visual Studio 2010 does not provide tools for upgrading applications and projects from Visual Basic 6.0. If you want to upgrade your project from Visual Basic 6.0 to Visual Basic 2010, you can use the upgrade tools provided with earlier versions of Visual Studio and then upgrade the project again in Visual Studio 2010.
Visual Basic Tools for Visual Studio
There's a plugin called Visual Basic Tools for Visual Studio that provides the following features:
load classic VB workspace- and project-files and offers quick access to the extension´s options
integrates with the solution explorer and the code editor having support for syntax highlighting, basic outlining (allows to expand/collapse methods, properties and types) as well as navigation bar support.
Classes, Types, Modules, Forms and Controls can be inspected using the Object Browser and Class View.
From the reading, it's unclear if you can actually build the project, though it does say:
The import tool creates a new solution and MSBuild compatible projects.

RAD Basic
There is also an independent IDE called RAD Basic that claims the following features:
New and modern IDE (Integrated Development Environment) with form designer supporting drag and drop, code completion, refactoring tools, etc.
RAD Basic Compiler: Compiler 100% compatible with your VB6 project (vbp, frm, bas and cls files). Generate native executables (exe and ocx) in both 32-bit and 64-bit.
RAD Basic Forms: Reimplementation of common VB6 controls and components supporting 32-bit and 64-bit.
etc.
Speaking from my experience, it's not easy to open a Visual Basic 6.0 project in any versions of Visual Studio above 2008.
Although 2008 and below versions do provide an automatic function to convert Vb6 code to the VB.net framework. But, the problem starts after the conversion - it can skip some code, add functions/variables on its own, or modify the functional behavior on its own, and with that the VB.proj will be created with errors and you will not be able to open it anywhere as a solution file. The same with any 3rd party tools.
If you want to open the VB6 code try Visual Basic 6.0 Portable edition.
But headache will still follow you there, please refer this link
Installation of VB6 on Windows 7 / 8 / 10
Make sure you are clicking on the project file itself... Right click on the file and select "Open With" and select your visual studio program. It may need to be converted and if so, it will prompt you to convert the project.
Thanks!

I know that there are millions of posts about this already but I cant seem to find one that mirrors my issue.
I am using VS2010 and want to automate excel and I'm trying to work through the example here.
MS Tutorial
The problem is when I go to add the reference as mentioned
3.Add a reference to the Microsoft Excel Object Library. To do this, follow these steps: •On the Project menu, click Add Reference.
•On the COM tab, locate Microsoft Excel Object Library, and click Select.
There is no such reference available.
Could someone please let me know if this is the right way to automate excel with VS2010.
If it is could someone please let me know why I dont have the COM option for excel.
Im wanting to write in VB.net but if someone has an example in C# that would be fine.
Kind Regards
Ash
I have tried implementing automation using the Microsoft.Office.Interop.Excel.Application dll but i get the following exception when I try to create the excel application.
This line generates the error.
EXL = New Microsoft.Office.Interop.Excel.Application()
This is the exception
Retrieving the COM class factory for component with CLSID {00024500-0000-0000-C000-000000000046} failed due to the following error: 80040154 Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG))
If you have Office 2010 installed on your machine but still don't see it in the COM tab then there are reasonable odds that you have the 64-bit version of Office installed. Visual Studio is a 32-bit program, it cannot see the registry entries for 64-bit COM servers.
Workarounds are to use the primary interop assembly, it ought to be installed on your machine. Use the .NET tab and select Microsoft.Office.Interop.Excel. Next option is to import the type library directly. Use the Browse tab and navigate to c:\program files\microsoft office\office14 and select excel.exe. Set the Copy Local property of the added references to True to avoid having to deploy the PIA to the target machine.
Also be sure that your app can run as a 64-bit process. In vb.net that's selected with Project + Properties, Compile tab, scroll down, Advanced Compile Options, set Target CPU to "AnyCPU".
I am trying to use the OneNote interop from visual studio 2010. I have OneNote 2010 installed, I am building a .net 2.0 win forms app. I add a reference, Select the COM tab, and choose either Microsoft OneNote 12.0 Object Library or Microsoft OneNote 14.0 Object Library. Regardless of what I choose, when I click ok my references list in my project shows Microsoft.Office.Interop.OneNote with a yellow warning icon next to it. If I try to compile I get an error:
The input file 'C:\Program Files\Microsoft Office\Office14\ONENOTE.EXE' is not a valid type library. D:\Develop\2.0\Projects\Office\OneNote\File Import\OneNote File Import\TlbImp OneNote File Import
I've done this before in earlier version of Visual Studio, is there something else I need to do?
No. I just tried and it works fine for me. Have you tried a project from scratch? Does it work if you target 4.0?
Can anyone help me on how can I import "System.Data.MySqlClient" in visual basic.net?
When I'm typing that code it produce an underline to the code and having an error of undefined namespace. How will I do?
Download and install the lastest .NET-Connector from www.mysql.com.
Add the MySQL.Data in Visual Studio to your project references (Menu: project, Properties, References).
Code!
