Ctrl+C Enabler for PowerShell

Summary

This is a .NET class library that allows you to enable Ctrl+C break on PowerShell console, always.

Why should be use this?

In some case, a PowerShell console, which is launched from Visual Studio IDE external tools menu, doesn’t accept Ctrl+C.

This class library can fix it :)

How to install in your PowerShell?

1. Download “CtrlCEnabler.dll” from release page, and save it into “%HOME%\Documents\WindowsPowerShell” folder.
2. Open the PowerShell console and enter the following command:

   PS> notepad $PROFILE

3. Then, the file “Microsoft.PowerShell_profile.ps1” is opened in a text editor.
4. Append lines as follows at the bottom of “Microsoft.PowerShell_profile.ps1”, and save it.

   # Enable Ctrl+C force.
   Add-Type -Path "$env:HOME\Documents\WindowsPowerShell\CtrlCEnabler.dll"
   [CtrlCEnabler]::EnableCtrlC() > $null

After this instruction, the PowerShell console always enables Ctrl + C break, even when launched from Visual Studio’s external tools menu.

How does it work?

This class library just calls the SetConsoleCtrlHandler Win32 API.

public static bool EnableCtrlC()
{
    return SetConsoleCtrlHandler(null, false);
}
