After adding a tab control and copying and pasting the text fields + buttons into a tab my windows form no longer works

I'm a C# noobie and have recently made a CRUD app with windows forms and decided to upgrade it a little by adding a tab function to add new functionalities to it but after copying and pasting the design of my windows form into the TabControl field, the design shows up but the CRUD system itself no long works.
I feel like I might need to call the TabControl in the form design code but have no idea how I'd do that. All of my CRUD code was made directly on the WinForm design class.
As #Idle_Mind mentioned in the comments, after pasting controls into the new tab all the events wired to them were wiped. After rewiring them the problem was solved!

Within the WPF Designer, what does Enabling/Disabling Project Code do?

I have no clue how long this feature/option has been around but my mouse happened to pause over this button within the WPF designer early and now I'm curious what it's purpose is.
Hovering over the button, Visual Studio pops up a tooltip that says Enable project code. When I click on it, the designer seems to reload the xaml contents but I can't tell what's changed.
What does this feature do?
2020 EDIT
It's been years since I've had to work in XAML, but I've received a new project where I need to work in XAML. This feature/button seems to have disappeared. Where has it migrated?
What does this feature do?
It enables or prevents the designer from running your code in the background.
Disabling project code can lead to a loss of design time data and enabling it can lead to unhandled exceptions in the XAML designer.
These exceptions are usually caused by code that attempts to access properties or methods which work differently when your application is running in the designer compared to when it runs as a built executable.

How to get button default style under windows 10?

Looking to my first steps with WPF on Windows 7 I was very pleased. Seeing it on Windows 10 I was very surprised. The buttons didn`t looks like expected. Trying it with WinForms results in the expected look an feel.
Here my problem:
So my question:
How can I get the "normal" style of the default button (OK has IsDefault=true) with the expanded blue border for the button even when it has focus, without defining the button-style myself?
This is very important in case of setting the focus to the Cancel-button programmatically, because in this case the dotted border will not be displayed, so on Win 10 the user can not know witch button will be pressed by enter.
You can get similar button styles using Windows UWP.
In WPF, you can check out the Modern UI(MUI) in MSDN site.
It can produce similar results. I have been working with mui for a couple of months and it really helped me to satisfy my client who wanted to have a Windows 10 like UI experience. I had to create tiles like in start menu also. MUI did a great job for me.
Get the MUI from Github. Modern UI for WPF
Also I had tried devexpress and telerik controls. Have a look at them too.

A window with no taskbar icon, no appearance in Alt-Tab and *without* using the ToolWindow extended style

I have a problem that appears to be new to Windows 10.
I want to create a form that is visible to the user, but with no task bar icon and that does not appear in Alt+Tab.
This is perfectly doable if one is happy to sacrifice the normal styling of a window by following the accepted solutions here for either WPF or Windows Forms.
The general advice for both WPF and Windows Forms is:
Set ShowInTaskbar to false
Enable the ToolWindow styling (either through setting the border style in WinForms or the WindowStyle in WPF)
However, this has a new, practical problem in Windows 10 when using Virtual Desktops: the moment you do the above, the WPF or WinForms window will appear in every virtual desktop. See my example application with a red background:
This affects both the Task View switching screen and the actual desktop itself. No matter where you go, the form is there!
Is there any way to show a form - or even just a bitmap - on Windows without anything appearing in the taskbar, without anything appearing in Alt+Tab and without duplicating the window on every virtual desktop?
I have spent two days researching every possible option, trying every example online, reading MSDN documentation on window styles etc. but all resort to the same method, either through P/Invoke calls or directly, but either way the result is the same.

How to solve Visual C++ window form disappearance?

I have a visual c++ program which has a few window forms. It does not have any error and can be built successfully.
