The Visual Studio Debugger Helped Me Bring an old MS-DOS Command Back From The Dead.

I previously showed how to display the output from DOS commands in a C# WinForms program. But I hit a snag with the Tree command. This displays directories and subdirectories on the branches of a tree-like structure where the branches are drawn using ASCII box-drawing characters. But my WinForms application doesn’t show the correct characters. That’s because it interprets them as Unicode characters. But ASCII and Unicode character codes are different - so the wrong characters are shown!
Fixing it is easy - I just need to substitute the Unicode characters for the ASCII characters. But finding which characters are causing the problems is a bit more difficult. For that, I need to use the Visual Studio Debugger and, in particular, the Immediate Window. If you’ve never used the Immediate Window, you are making your debugging life harder than it needs to be. In this video, I explain why.

Actualy it is a Windows command.
