Code stops executing when a user clicks on the console window

Question

I\'ve got a console application that executes my code without user interaction. If the user clicks within the console window, on purpose or on accident, all execution stops. <

I just saw that this answer linked in the comments of OP's question contained what I found by myself. I will keep my answer because people might not see it, just like me, and it would spare them a lot of time.

Jim's answer did not work for me, I couldn't figure out why. I dug around and found a solution that works, so I'll share my findings, hopefully helping someone in the same situation.

The problem was with the handle that I got from GetConsoleWindow(), it gave a Win32 error (0x6) where the handle is invalid when I tried to use it. The call to SetConsoleMode() did nothing.

To get a working handle, I used GetStdHandle() to get the Input handle for the console. Add this to Jim's code :

public const int STD_INPUT_HANDLE = -10;

[DllImport("Kernel32.dll", SetLastError = true)]
public static extern IntPtr GetStdHandle(int nStdHandle);

Then replace GetConsoleWindow() by GetStdHandle(STD_INPUT_HANDLE) in DisableQuickEdit() and EnableQuickEdit() in Jim's code.

After calling DisableQuickEdit(), the selection is disabled in the console.

Thanks Jim !
