Giới Thiệu · NavControlX

NavigationControlX is a Microsoft .Net 2.0 composite control used as a record navigation control with tape machine style buttons. Allows for dual speed fast scrolling in either direction and includes buttons for First, Next, Fast Forward, Fast Reverse, Previous and Last record. Exposes properties for accessing values that are enumerated through an index. Not a binding control, but rather a mechanism for determining record navigation pointers and the visual display of such pointers. Useful for developers who wish to have a simple, easy to implement, but elegant navigation control for collections too large for other controls. When user selects button the counter is updated and current index is returned as a number whose value is the relative position in the object. It is up to the programmer to determine what to do with this current index number. By simply handling the public event when the current index changes the programmer can assign values to appropriate controls on a form. The current index is relative to the first record and may be 0 or 1 based indexing (default = 0). Help file includes sample code. Three sizes to choose from. Moves very quickly and will not cause lag. Unit testing complete and CLS compliant. MessageBoxX - Another library included with the NavigationControlX.dll, this class allows for message boxes to be centered on parent form and also set a timer for the length of time the message should be displayed before disappearing. When form parameter is omitted then the message box displays center screen. Timer is disabled by default and can be set through public property "TimerOn". Timer interval is set through property "TimerInterval ". User is allowed to make instance of MessageBoxX or use MsgX which is provided on the module level. Two other public items worth mention on the module level are ErrMsgX which uses instance variable MsgX in order to display exceptions that are useful to developers yet readable by users. Having a centralized place for dealing with exceptions is what this method is intended for. The other is a property for limiting the width of the message boxes as a result of limiting the width of a string. An instance of the class does not make instances of messages until either overloaded method "Show" is called. Listed below are module and class declarations and XML documentation.
