An error was encountered during code generation visual studio

First off, I wish I had more information to give you but I am kinda puzzled with this error from Microsoft Visual Studio 2015:

An error was encountered during code generation. The changes you have
made in the designer have not been committed to the source code. It is
recommended that you close and re-open the source file. The error
message follows: Value does not fall within expected range.

A bit of additional information I hope will be useful… This has been my first time encountering this nagging and persistent error. Right after my day job, I sat right down on my computer and started working happily away on my lil programming project. Everything was good, VS2015 Community started up like usual, but AS SOON AS I PLACED ONE BUTTON (literally, one button… dragged and dropped… didn’t change anything else…) from my toolbox onto my winform, this agitating error pops up screaming nonsense. I worked for hours on my little project yesterday, debugged and tested everything before I went to bed and it all worked perfectly fine. I was happy.

I did some online research, and tried everything from repairs/reinstall to VS2015 as well as other things, like making sure all my columns in my SQLSERVER Express DB are set Visible = True. They were. I tried closing and reopening my project, VS 2015 and even restarting my desktop. This awful error is persistently following me for dragging and dropping a button on my winform, and I hope I don’t lose my project. The backup save I tried to load is doing the same thing as well. I also read this was supposed to be an issue fixed with SP1 for VS? Just in case, I made double sure I’m currently up to date with fixes and downloads from Microsoft for VS.

Has anyone run into this error?! If so, please advise on how to fix and save my behavioral statistics calculator!! Thanks Overflowers!

I got this message after creating a TableLayoutPanel and moving some controls into it. At that point, I couldn’t save the source file, the Designer file, our either from the [Design] view.

I was able to undo the last changes by selecting everything in the Designer.vb file, cutting it to the clipboard, and saving. No error message. Then I pasted everything back, saved again, and there was no error message. I checked the [Design] and the TableLayoutPanel was gone, but my controls were where they were prior to adding them to it.

After that I repeated the same steps to add the TableLayoutPanel and put the controls in it and I got no error message. It was relatively inexpensive in terms of wasted time to deal with this message. I’m not sure what would have happened if I had closed the solution according to the messages suggestion but I didn’t need to find out.

This may not be the answer, but may lead to a solution to you or somebody else.

I came to this question because I’ve got the same message

«An error was encountered during code generation. The changes you have
made in the designer have not been committed to the source code…»

In my case, I created an UserControl with a Boolean property called Vertical. I added this UserControl to a Form. Everything worked, I could see the programmed behavior on the Form designer flipping Vertical property from True to False and viceversa.

Days later, I decided it would make more sense to rename the Vertical property to Show_Vertically. And few minutes later the message was there.

It turns out that whenever I added the UserControl to a Form, the designer automatically generates code inside its InitializeComponent() routine with the initial UserControl1.Vertical = True

The solution is either to change the statement inside the hidden InitializeComponent() routine or to remove and add the UserControl to the Form again.

From your comments above, I assume your error was in your SearchInventButton. I would get inside the InitilizeComponent() routine and look for any property assigned to SearchInventButton. If the button is not the problem, it may be any non-standard control that got updated like I did with mine. (You were talking about some SQL columns, did you removed some columns or changed their name? It may be that the designer assigned some format to those ones and now the designer can’t find the column) But without further details, these are my 2 cents to the community.

Follow this steps:

1.Create a new project.

2.Copy your code and all controller to new project (step 1).

3.Exit from old project(Will not be saved) without saving.

4.Re open old project(step 3).

5.copy your all source and all controller(from step 2) to your project.

6.Save your Project.

I received the same error and all I did was open up the code page and delete everything on the page. I was then able to save all. Once I did that I closed and reopened Visual Studio and then reopened my project.

I hope this helps.

open your source code page
cut every thing
then start the project
you will receive an error
edit then past your code agine

and start your project it worked for me

If there is anybody new to C# also, like me, I encountered it months ago, and the problem «solved itself». At that time I was still like early new to C#, with a bit of Pyhton knowledge.
And today I encountered this error again, also on a personal project I’m working on…

And I accidently came across the solution, I was struggling heavily to fix it, becasue I made BIG changes to my form, and stressed because of all the changes I had to redo after restarting VS..

Well, you have the «mainpage(or whatever you named your form)».cs(design) tab and then the script/C# file for it, namely «mainpage.designer.cs» which has a lot of «this.whatever = new System….» in it.
Your error lays there, litterally change anything, even adding a letter anywehere randomly, and try to save, then just undo the changed, and save again.

It worked for me, though.

If I ever come across the same error in the future, I will test this method again, and reply to this message as an update.

And great day furtheron programming!!

Question

I’m trying to make a Windows form application in Visual Studio 2015 Express (Visual Basic) with a datagridview not bounded to data. I add some columns and make one off them not visible. Save the solution, OK.

With the designer I change the column property to visible. When I try to save the solution the following error appears:

“An error was encountered during code generation. The changes you have made in the designer have not been committed to the source code. It is recommended that you close and re-open the source file. The error message follows:
Value does not fall within the expected range.”

Using VS2013 I found after some research that the problema was that in the source code the property remains as «Not visible» and I only can save the solution editing manually the code and changing the value to «True» or removing the line.

But if I define the column as «Visible» and then change is value to «Not visible» with the designer, the change appears in the source file. It looks like only the value «Visible» is not save.

I already tried to reapir the instalation of VS2015 but everything remains the same, and this problema does not exist in VS2013.

Is this a bug of VS2015 or something else is wrong?

Catastrophic failure (Exception from HRESULT: 0x80000FFFF (E_UNEXPECTED)

and it gives me a blank document. If I click the button to Save All open documents, the whole damn program just crashes!! I’ve submitted the error reports, but that’s not going to help me fix the problem. what is going on. this has never happened before!! I just barely installed visual studio so how in the heck could there be something wrong. I can’t do ANYTHING now!

It is difficult to exactly find out what is going wrong here so I recommand that you do the following:

Make sure that you install the latest updates + Service Packs for Visual Studio 2005 and .NET Framework to make sure that the issue you are experiencing hasn’t been resolved yet
Start Visual Studio 2005 (instance A)
Start Visual Studio 2005 (instance B)
In instance B select menu Debug => Attach to Process and then choose instance A
Select «Native» and «Managed» code
In instance A perform all the steps you described to make Visual Studio crash
In instance B you can then create a dump file from menu Debug => Save Dump as.
Also make sure that you send the report
Create a new report on the following web site:
http://connect.microsoft.com/feedback/default.aspx?SiteID=210
In this report attach the generated dump file
Also copy + paste the entry in the event log to the bug report. This event log entry contains the report ID that you send before to Microsoft. They will use this number to look up the report send by Watson.

You could also try to analyze the dump file yourself using WinDbg but this is easier said than done.

Failed to view the validation code because of the following error:

Error HRESULT E_FAIL has been returned from a call to a COM component

The only thing in my solution is the dataset. I am quickly going insane.

I know how it feels. Here are some more things you can try:

Have you tried a different installation media for the Visual Studio environment. I mean did you burn an img file to a DVD or is it a DVD with scratches on or something?
Do you use Registry Cleaners?
Have you tried installing Visual Studio without SQL Server 2005?
What is the version number of the c:windowssystem32mscoree.dll file?
Enable Visual Studio logging by launching devenv.exe /log. This will create a xml based log file in the following folder:
%USERPROFILE%Application DataMicrosoftVisualStudio8.0ActivityLog.xml

Here is how I always install my machine:

Install Windows XP Pro or Windows Vista
Retrieve all the latest updates from the Microsoft Update site (this includes the .NET Framework versions)
Install Visual Studio .NET 2003
Install Visual Studio 2005
Install SQL Server 2005 Developer Edition

What I recommend you do is download Microsoft Virtual PC and try it there instead of reinstalling your machine everytime:

You can work with a master disk where you install only Windows XP without all the updates. Then you create a new Virtual Machine that uses this master disk as it’s base. In this 2nd VM you install all the updates and Visual Studio et al.

It’s a technology of which you will hear more and more of. It’s a technology of the near future. It is called Virtualization:

When you use Virtual PC you can create Virtual Machines that simulate a computer environment in which you can install a platform and try out software.

Catastrophic failure (Exception from HRESULT: 0x80000FFFF (E_UNEXPECTED)

i exited, reopened the project and this time the first thing I did was build the program (the dataset was still there as I had saved it) and THIS time, I didn’t get the error. then I added a column to the dataset, and tried to save.

Microsoft Visual Basic Compiler has encountered a problem and needs to close. We are sorry for the inconvenience.

WHAT THE . is going on?!

Can you please specify exactly what you install in which order including Data Access Components if any. Also do you get this error everytime? Or is just this one project?

We need to know the correct order of your actions before the crash, as I have understand it:

Create a new project (Class Library, Windows Forms, Web Application ?)
Add a dataset to the project
Add a datatable
Add some columns
Save
Crash

Or did I miss any steps?

I just started getting the same problem (slightly different context though). and its making my hair fall out.

My installation is VS2005 and it has been fine for a couple of months.

I just posted a message in microsoft.public.dotnet.general

Reads as follows:

Yesterday I changed one of my forms by removing a listview and a couple of
buttons (contained in a tab page). These were recreated in a user control
within the project and then added back into the form as a single object.

The problem then appeared three times where I had made minor alterations to
the form and then hit «Save» (fortunately I’d made frequent backups :@).

Basically the save failed and the entire contents of the form were erase and
it was no longer possible to look at the code behind the form.

I have just recreated the problem by opening the form for edit, resizing a
rich text box and then clicking save. This time not all the objects
dissapeared and I am still able to view the code window — though its pretty
much empty.

First error displayed said «An error was encountered during code
generation. Catestrophic failure (Exception from HRESULT: 0x8000FFF
(E_UNEXPECTED))», then another error just popped up saying «An error was
encountered during code generation. Value does not fall within the
expected range». Note that the second error message popped up before I’d
OK’d the first and repeated itself 3 times.

All code has been stripped from the form with the exception of
«#Region. #End region» There are still a couple of bits of «Windows Form
Designer Generated Code» but all the work is lost and the errors keep
popping up.

I have been able to make changes and «build» this project a few times since
I started getting the error and it does not seem to happen consistently.
Anyone have any ideas what I might have done wrong?

Создаешь класс,наследник от TypeConverter,например MyButtonConverter.
Переопределяешь его методы,достаточно только CanConvertFrom,CanConvertTo,ConvertTo,GetPropertie s.
Создаешь еще один класс,наследник от Button,например MyButton. Приписываешь этому классу аттрибут [TypeConverter(typeof(MyButtonConverter))].

В своем компоненте делаешь открытое свойство типа MyButton.

После этого в дизайнере должны быть видны свойства кнопки
