LeftButton 1

等效于 Visual Basic 6.0 常量 vbLeftButtonEquivalent to the Visual Basic 6.0 constant vbLeftButton.

MiddleButton 4

等效于 Visual Basic 6.0 常量 vbMiddleButtonEquivalent to the Visual Basic 6.0 constant vbMiddleButton.

RightButton 2

等效于 Visual Basic 6.0 常量 vbRightButtonEquivalent to the Visual Basic 6.0 constant vbRightButton.




在 Visual Basic 6.0 中,鼠标按钮参数掩码常量用于表示各个鼠标事件处理程序的 Button 参数中鼠标按钮的状态。In Visual Basic 6.0, mouse button parameter mask constants were used to represent the state of mouse buttons in the Button parameter of various mouse event handlers. 在 Visual Basic 中,鼠标事件的参数已更改,并且不再需要这些常量。In Visual Basic, the parameters for mouse events have changed and these constants are no longer necessary. 这些常量使已从 Visual Basic 6.0 升级的代码可以继续运行,而无需进一步修改。These constants enable code that has been upgraded from Visual Basic 6.0 to continue to run without further modification.


Microsoft.VisualBasic.Compatibility.VB6 命名空间中的函数和对象用于工具从 Visual Basic 6.0 升级到 Visual Basic。Functions and objects in the Microsoft.VisualBasic.Compatibility.VB6 namespace are provided for use by the tools for upgrading from Visual Basic 6.0 to Visual Basic. 大多数情况下,这些函数和对象可再现 .NET Framework.NET Framework 中其他命名空间的功能。In most cases, these functions and objects duplicate functionality that you can find in other namespaces in the .NET Framework.NET Framework. 只有当 Visual Basic 6.0 代码模型与 .NET Framework 实现有显著区别时,才必须使用这些函数和对象。They are necessary only when the Visual Basic 6.0 code model differs significantly from the .NET Framework implementation.
