C# 클래스 ZForge.Controls.TreeViewAdv.NumericTextBox

Restricts the entry of characters to digits, the negative sign, the decimal point, and editing keystrokes (backspace). It does not handle the AltGr key so any keys that can be created in any combination with AltGr these are not filtered

WndProc ( Message &m ) : void	Method invoked when Windows sends a message. This is over-ridden so that the user can not use cut or paste operations to bypass the TextChanging event. This catches ContextMenu Paste, Shift+Insert, Ctrl+V, While it is generally frowned upon to override WndProc, no other simple mechanism was apparent to simultaneously and transparently intercept so many different operations.
