Windows 10: VS 2019 Form Design Environment won't display controls when a tab is selected

I'm a C# developer and just brought a product back out of retirement after many moons. At the time I mothballed the thing the entire IDE for VS2019 Community Version was working properly. During the down time I upgraded to Windows 11. I didn't immediately check to see if the project was still working hindsight being what it is. Once I opened the project and double clicked on a form WinForms was what I was using at the time, compiled it and ran it all seemed well. Then I dropped into the form designer and to my horror, I could no longer select tabs on a tab control and have the controls on

4870x2 won't display at 1680x1050 at all!

OK. Now I know what ur problem is. Step by step:
1. Go to Catalyst Control Center
2. Click on the word "Graphic" right on top left corner. It will display drop down menu
3. Click on Display monitor and will see the list of monitor at near bottom
4. Right Click the monitor and select "Configure". It will show up the window
5. There will be 3 option to select. Select the middle one and then click on the tab which show the bar with 15%.
6. Drag the bar to max, and the screen will stretch to the native resolution 1680x1050.
7. Also click the tab with showing RGB drop down list and select the last one (it will change to image quality for pc).
That's it. Good Luck.

 

How do you view the GUI of the form in Visual Studio 2019?

I am trying to create a Windows Form Application in Visual Studio 2019 but when I create the project the form code shows up but no tab for the actual form is there. I need the form to place the controls and design the GUI but for some reason I can't edit
the GUI of the form.

 

System environment variable won't stick

Running Win10 Home on an Acer Spin 3, 64bit, i7cpu. I try to add a path to the system environment variables by:

1. Control Panel > System > Advanced system settings > Advanced tab > Environment variables

2. The "Environment Variables" window opens.
3. In the "System Variables" pane I select "Path" and click the EDIT button.
4. A list of the current system paths is displayed.
5. I click the NEW button, browse to the path I want to add which is "C:\Python36-32" and click OK. The path "C:\Python36-32" is added to the list of current system paths.
6. I click OK and am returned to the "Environment Variables" window.
7. I click the "X" at the top right to close the "Environment Variables" window.

Now if I click the "Environment Variables" button again (end of step-1) and repeat steps 2-4, the new path I added in step-5 is gone. IOW, adding a new path won't stick.

What am I doing wrong?
