Efficient roguelike grid FOV / shadowcasting / line of sight in a single C function inspired by https://docs.microsoft.com/en-us/archive/blogs/ericlippert/shadowcasting-in-c-part-one
// Copyright (c) 2021 Stoiko Todorov

// For a copy, see https://opensource.org/licenses/MIT.
// What this function does:
// Rasterizes a single Field Of View octant on a grid, similar to the way
// field of view / line of sight / shadowcasting is implemented in some
// roguelikes.
// Uses rays to define visible volumes instead of tracing lines from origin
// to pixels.

Currency Format Input Field

Currency Format Input Field

Auto format currency input field with commas and decimals if needed. This is how I would personally expect one to work. Works left to right without forcing user to enter 00 cents if there is none. Text is automatically formatted with commas and cursor is placed back where user left off after formatting vs cursor moving to the end of the input. Validation is on KeyUp and a final validation is done on blur.

Enable LDAP over SSL (LDAPS) for Microsoft Active Directory servers.

Enable LDAP over SSL (LDAPS) for Microsoft Active Directory servers

Microsoft active directory servers will default to offer LDAP connections over unencrypted connections (boo!).

The steps below will create a new self signed certificate appropriate for use with and thus enabling LDAPS for an AD server. Of course the "self-signed" portion of this guide can be swapped out with a real vendor purchased certificate if required.

Steps have been tested successfully with Windows Server 2012R2, but should work with Windows Server 2008 without modification. Requires a working OpenSSL install (ideally Linux/OSX) and (obviously) a Windows Active Directory server.
