在调用一个用户界面时候按照以下操作流程：
LoadPanel -> DisplayPanel -> RunUserInterface
QuitUserInterface -> DiscardPanel
首先用户界面时候，在Load时候就是将资源加载，并返回该Panel对应的一个编号（int Panel = LoadPanel（*,*,））；在后续DisplayPanel、RunUserInterface、QuitUserInterface与DiscardPanel时候就是使用Panel作为访问接口。
LoadPanel说明
int LoadPanel (int parentPanelHandle, char filename[], int panelResourceID);
Loads a panel into memory from a user interface resource (.uir) file or text user interface (.tui) file you created in the User Interface Editor.
parentPanelHandle -- Handle of the panel into which to load the panel as a child panel. Pass 0 to load the panel as a top-level window.
CVI运行元素
Panel：程序运行面板
Control：控件
Event：事件，也就是对应“*.C”中的Callback函数
Data：Data可以是用户定义或者系统函数参数返回给我们的，可以拿来用与判断、传值、触发响应等。
