有一段时间我试图在常见的VBNET密钥处理程序下捕获Ctrl Alt右移键.
这是我的测试：
这是我的测试：
If e.Control And e.Alt And e.KeyCode = Keys.Space Then
MsgBox("CTRL + ALT + SPACE") ' This work
End If
If e.Control And e.Shift And e.KeyCode = Keys.F10 Then
MsgBox("CTRL + SHIFT + F10") ' This work
End If
If e.Control And e.Alt And e.KeyCode = Keys.ShiftKey Then
MsgBox("CTRL + ALT + SHIFT") ' This work
End If
If e.Alt And e.Shift And e.KeyCode = Keys.LWin Then
MsgBox("ALT + SHIFT + LEFT WINDOWS") ' This work
End If
If e.Control And e.Alt And e.KeyCode = Keys.RShiftKey Then
MsgBox("CTRL + ALT + RIGHT SHIFT") ' This don't work
End If
Windows 7,WinForms,VB2008,.NET framework 2.0
为什么我在描述的情况下无法捕捉Ctrl Alt右移键？
或者,如何捕获Ctrl Alt右移键组合？
使用标准VB.NET方法无法检测Shifts之间的差异.
您必须为此挂钩Windows API：
