For some time I'm trying to catch Ctrl + Alt + Right Shift Key under common VBNET key handler.
Here are my tests:
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框架2.0
Why I can't catch Ctrl + Alt + Right Shift Key in described situation?
Or, how do I catch Ctrl + Alt + Right Shift Key combination?
使用标准 VB.NET 方法无法检测班次之间的差异。
为此，您必须连接 Windows API：
<System.Runtime.InteropServices.DllImport("user32.dll")> _
Private Shared Function GetAsyncKeyState(vKey As Keys) As Short
End Function
Private Sub Form2_KeyDown(sender As Object, e As KeyEventArgs) Handles Me.KeyDown
If e.Control And e.Alt And e.Shift Then
If Convert.ToBoolean(GetAsyncKeyState(Keys.LShiftKey)) Then
MsgBox("CTRL + ALT + LEFT SHIFT")
ElseIf Convert.ToBoolean(GetAsyncKeyState(Keys.RShiftKey)) Then
MsgBox("CTRL + ALT + RIGHT SHIFT")
End If
End If
End Sub
