Add Application.EnableVisualStyles()

[rowo360]

Describe the bug
I propose that we add the Application.EnableVisualStyles() statement to our application.
It's an innocent-looking one-line statement and the Microsoft documentation is more a black-box than a detailed description about the individual features (link). So I cannot provide a list of expected changes.

However I missed certain functionality, which will be solved by the Application.EnableVisualStyles() statement:

• Pressing Ctrl+A in the text filter Textbox doesn't select all content. However, I regularly use it (in all other applications) to select the entire text and then press delete. Application.EnableVisualStyles() will solve it - although I don't have an idea why this is related to 'VisualStyles'. But I'm glad that I got a hint in this direction by a google search.
• The icon in the MessageBox is somehow pixelated. I guess that's related to my 4k display.

Again, Application.EnableVisualStyles() will solve this.

Please have also close look to the buttons in the two screenshots: the corners are now rounded and there's a visual hover effect when moving the mouse over a button. Not only in this MessageBox dialog, but for all buttons - for example the TestParameter dialog.

However, that's only one example - in general I understand it that with the EnableVisualStyles() statement the built-in Windows theming to style controls is used instead of the "classic Windows" look and feel. If the computer is running without a style, then you wouldn't notice any difference.

So overall, I've the impression that we should use this statement.
Or has this already been discussed and decided in the past?

BTW: If creating a new Windows Forms application from scratch, the Application.EnableVisualStyles() is already included now.

Environment (please complete the following information):

• TestCentric Version:2.0.0-beta6
