You can get this version from Util - Windows Handles Viewer (Simple GUI with REPL) v1.0.exe
And this is what the default GUI looks like:
To try out the C# REPL , drag the Target Icon into the TextBox below (shown in red below)
Then un-comment the line below Task #1 and click on Execute (note how the TextBox value was changed)
To see how you can also change the text of a Handle whose value you discovered, use the Handle value (in this case 657236) in the code (replacing 12345 as mentioned in the Task #2 instructions) and click execute:
And as shown in Util - Windows Handles Viewer (Simple Gui) v1.0.exe , this will work on other windows and processes :)
