How to compile legacy VB6 code
Where can I find an IDE for VB6? I'm guessing I need to get a copy of Visual Studio 6, but I've been googling for hours and I can't find anything.
I need to do some simple maintenance on an old VB6 application. Upgrading it to .NET would cause lots of work on the deployment and testing side of things so I would prefer to avoid that. And I would rather not resort to notepad and command line compiler either.
Is there any better solution to my problem?
Legal options:
There are many copies of visual studio 6.0 on eBay that look legit.
Find someone that has VB6 and have them fix it.
Get an MSDN subscription (unsure which level is needed - Hans says Universal includes VB6)
If converting to VB.NET is an option, you could check out Microsofts upgrade assement tool at:

I can't believe VB6 is still alive, not too long ago I had to write an ActiveX control for use with VB6.

What are the differences between Visual Studio Code and Visual Studio?
(14 answers)
Closed 12 days ago.
Apologies if this doesn't belong here. I tried Reddit, but got trolled. I'm just at a loss and am struggling to follow tutorials, etc because of it.
I'm coming from an exclusively Python background and have always used Pycharm. I'm now attempting to learn Java & the React fw and would like to use MS Visual, but am confused on why my interface is completely different from every other one I am seeing.
I realize this is a basic question, but I think if I can just figure it out, I'll be able to resolve a few other issues I'm having as well.
This is what their interface looks like
This is what mine looks like
I've tried researching the issue but have not had any success.
You're using the incorrect software. Your first screenshot is using Visual Studio Code which is a code editor (not an IDE) that is completely separate from the Visual Studio IDE.
Trying to do this on Windows 10.
I have a VB6 folder and I'm trying to make a solution out of it.
Visual Studio succeeds in making a project, but when trying to compile it gives millions of errors (see image).
I've read conflicting info about VB6 support in Visual Studio.
On one hand it's written that Visual Basic is supported, but not VB6?
There also used to be a VB6 IDE, but I can not find a download for it.
Should I use Visual Studio 2008 or something?
What are my options?
Thank you.
When Microsoft today uses the abbreviation "VB", they usually mean "VB.NET", the successor of classic VB published by Microsoft in 2002. According to this source, the latest version of VB, called VB6, appeared in 1998, and 10 years later Microsoft dropped any support for VB6 and its IDE.
Unfortunately, VB.Net is not backwards compatible to VB6, it is a different programming language (though it has some properties which arguably make it easier to port VB6 to VB.Net than to other .Net languages like C#). You cannot compile VB6 programs directly with Visual Studio 2002 or later, you usually need the original VB6 IDE. That leaves you basically with two options:
Try to find a copy of the old VB6 IDE and compile the program with it (if you cannot get it from where you got the source code, according to the comments, you may have luck at Microsoft, when you have the right developer subscription level).
Port the VB6 application to VB.Net. For this, however, you should have some not-too-basic knowledge of both languages, know the differences and ideally have an environment where you can test the original application against the ported one. I did this by myself in the past for some applications, so I know it can be less effort than recreating an application completely from scratch. However, this depends a lot on the specific application, how large and complex it is, how large the UI parts are and which kind of 3rd party components were involved. To be honest, if the application is not trivial, you should have a VB6 IDE for this approach, too.
Note also when your old VB6 code uses 32-bit third party OCX/ActiveX components, for porting it to VB.Net I would recommend to use VS2019 or an earlier version, not VS2022. The current Winforms Designer of VS2022 is not compatible with 32 bit OCX components any more, and it is unclear if MS will ever publish a version which will be.
i have a vb 6 prroject itried to open it on vs 2013 by installing extension name as vb 6 for visual studio from console manager now i the error is that extension is not compatible so i google that its mean vb 6 project cannot be upgraded so instead of wasting time i am asking is there any tool to run vb 6 win form gui app so that i can open my source code , can you give me that downloading link of tool too
i have extension frm , with my forms in vb 6 so please
as vb 6 is not a part of .net technology so it will never run on visual studio
Simple answer: VB6 is long past end of life from Microsoft.
None of Microsoft's existing tools will even read VB6 sensibly. VB.net is NOT VB6 in any way or form.
If you want to develop/enhance/extend a VB6 program, you need a VB6 development environment. Some say this is available via MSDN. Otherwise it is pretty hard to find.
As a practical matter, if you want to move this VB6 program to a modern language, you'll need to find a migration tool/vendor/service that understands VB6 to do this for you, or do it yourself (which usually fails unless the project is really small). And yes, converting the forms is hard.
Even if you fork over the cash for an MSDN subscription to get access to the necessary tools it takes time to develop proficiency in a new language and those tools for using it. Many companies take the smarter path and hire a contractor with both the tools and the experience to handle maintenance of their legacy VB6 portfolio.
This saves the expense of porting such applications to another language and limits the risk of such a port having data-destroying flaws.
You could use VS2008, but you'll probably still have a lot of work to do.
Depending on what you need this VB6 code for, you might be able to copy it into the VBA (Visual Basic for Applications) section of a Microsoft Office document. As I understand it, VBA is nearly identical to VB6 from a programming-language and capability point of view.
Note that this would not allow you to compile code to a standalone EXE or DLL, but if you don't need to do that it might be an acceptable workaround for not having the VB6 development tools.
Here is a link to Microsoft's primer on VBA: MSDN VBA Primer.
Also, be aware that most VB6 source code files (excepting FRX files) are plain text so if you just need to read them, you can use any text editor.

No IntelliSense for c++/cli in visual studio 2010?
As the title already states, nothing gets popped up or syntax checked. In the status bar, the following message is displayed.
Intellisense 'Unavailable for C++/CLI'
Usually I am using native C++ in Visual C++ 2010 Express.
In Visual C++ 2008, Intellisense was working correctly for C++/CLI, so I guess it should be working in this version too.
The IntelliSense parser in the C++ IDE was due for an overhaul, it had chronic problems that didn't get better with each release. Random corruption of the .ncb file, the IS database was rampant. For VS2010, it was completely rewritten, a new parser and a new way to store the results. Now an .sdf file, a SQL Compact database. The parser was written by the Edison Design Group, they are famous for being the only ones that ever wrote a C++ parser that completely implements the standard.
Sadly, they didn't have the resources to give C++/CLI the same treatment. The work is deferred, it definitely won't make it for SP1. The connect feedback report is here, only 24 votes. Cast your vote.
EDIT: this was taken care of in VS2012, it again supports IntelliSense for C++/CLI. And C++/CX, a language extension to support WinRT that has a syntax that is very similar to C++/CLI, the likely inspiration to get this work done.
From http://connect.microsoft.com/VisualStudio/feedback/details/459187/intellisense-unavailable-for-c-cli :
Hi,
As the team that invented C++/CLI, we are firm believers that it's one of the best ways to interact with managed code (whether it's to expose native objects or consume managed ones).
I want to make it clear that while we can't address this issue, we reduced support for C++/CLI only due to time and resource constraints. This is NOT an indication that we are distancing ourselves from the technology. You can still see managed classes in Class View, search for symbols, get definitions/declarations and the Winforms designer and Unit Testing functionality continue to work.
Unfortunately, it would have taken a long time to add full support for C++/CLI semantics to our new Intellisense parser and we wanted to get this into the hands of native developers in the meantime. We are sorry we couldn't do it all in one release and we eventually intend to bring this support into the Intellisense engine.
Thanks,

When I try to start my visual basic to open a project it doesnt seem to be working and keep prompting a error 'VB6EXT.OLB' could not be register. What does that mean? Need helps on this matter, thanks
Just Right Click on VB6.exe and CLick On Run As Administrator..
Hope It works
VBE6EXT.OLB is the Visual Basic for Applications Extensibility Library. That filename seems to indicate that you're dealing with version 5.3, which apparently shipped with Microsoft Office 2000. It would seem your VB6 project is an Office Automation project then?
Google turns up the following links, which may be helpful:
BUG: Interface methods in the VBA Extensibility Library (VBE) are changed
PRB: Visual Studio Setup program may include Office OLB files in setup list
Neither seems to directly answer your question, but they seem like a good place to start.
Since Visual Basic 6 (and Microsoft Office 2000 as well) hit end-of-life well before Windows Vista was released, there may be a fundamental conflict between them. You might be better off trying to develop your application on an older version of Windows.
This just happened to me (literally seconds ago) and I came HERE first stop.
I was looking for THE answer. As it happened, MS-Office 2010 offered to repair the problem...
... and, skeptically, I accepted.
To my astonishment I was soon greeted by my FAVOURITE splash screen in the world - I've got my Rubberduck
Anyway, I'm relieved the Auto Fix worked...
