Tabctrl like UltraEdit saw a lot, the application is very extensive, but sometimes the interface needs vertical TabCtrl, like Acrobat, MSN, QQ, etc. I have made a vertical row because of the need for application. TabCtrl, similar to UltraEdit, the similar function of Ctrl, can dynamically increase the deletion of Button; select message, double click, right-click message, etc .; the current support for TooltiP; nor support for horizontal chart (I hope It can be supported, but the time is not to implement it), the control is used by the MFC, derived from cdialogbar, in order to use for MDI or SDI, of course, the base class can be changed to CWND
