这个是用C#做底层开发车辆管理系统，代码运行效率高-This is the C# Make the bottom of the development of vehicle management system, code running efficient

C# 实现Windows输入法的全角与半角切换功能，加载窗体时，焦点默认处于TextBox1上。在控件的Click事件中触发来调整输入法状态，检查输入法的全角半角状态，如果输入法处于打开状态，如果是全角，ImmSimulateHotKey(h,IME_CHOTKEY_SHAPE_TOGGLE);//转换成半角。

用了斯坦福的cs111库编的（学校用来启蒙的库），由于不了解键盘输入的库，便采取鼠标点击控制方向-spent the cs111 Stanford Bank (schools used to enlightenment library), and the ignorance of the keyboard input of the library, they should take control of the direction the mouse click

Delphi将指定菜单项添加到TreeView中，可将主界面菜单栏中的菜单项，添加到界面左侧的树形菜单控件中，这个树形菜单看上去相当不错，设计漂亮，而且在众多的Delphi软件编写中，都有很高的几率要用到TreeView菜单，因此这个例子对Delphi编程者来说，是值得作为设计素材以及学习参考的哦。
