Switch branches/tags

Name already in use

A tag already exists with the provided branch name. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. Are you sure you want to create this branch?

ANSICON Latest release

ANSICON provides ANSI escape sequences for Windows console programs. It provides much the same functionality as ANSI.SYS does for MS-DOS.


  • 32-bit: Windows 2000 Professional and later (it won't work with NT or 9X).
  • 64-bit: AMD64 (it won't work with IA64).

How it Works

ANSICON injects a DLL into a process, hooking its functions.


One of three methods is used to inject the DLL.

  • LoadLibrary via CreateRemoteThread for a running process.

  • LdrLoadDll via CreateRemoteThread for a 64-bit .NET AnyCPU process.

  • Adding the DLL directly to the import table, otherwise.


Hooking is achieved by modifying import addresses, or the return value of GetProcAddress.
