私が見ている問題は、2 つの修飾子を追加MOD_CONTROL
しMOD_SHIFT
、それらをコンマで区切って、4 つしかかからないにもかかわらず、関数に 5 つのパラメーターがあることを示していることです。このように Modifers を一緒に Oring してみてください。また、修飾キーが正しくないように見えるドキュメントで確認する必要があります。
Private Sub Form1_Load(ByVal sender As System.Object, _
ByVal e As System.EventArgs) Handles MyBase.Load
RegisterHotKey(Me.Handle, 100, MOD_CONTROL Or MOD_SHIFT, Keys.D2)
RegisterHotKey(Me.Handle, 200, MOD_CONTROL Or MOD_SHIFT, Keys.D3)
RegisterHotKey(Me.Handle, 300, MOD_CONTROL Or MOD_SHIFT, Keys.D4)
End Sub
それが述べているドキュメントから(強調鉱山):
fsModifiers [in]
タイプ: UINT
WM_HOTKEY メッセージを生成するために、uVirtKey パラメーターで指定されたキーと組み合わせて押す必要があるキー。fsModifiers パラメータは、次の値の組み合わせにすることができます。
Value Meaning
MOD_ALT 0x0001 Either ALT key must be held down.
MOD_CONTROL 0x0002 Either CTRL key must be held down.
MOD_NOREPEAT 0x4000 Changes the hotkey behavior so that the keyboard auto-repeat does not yield multiple hotkey notifications.
Windows Vista and Windows XP/2000: This flag is not supported.
MOD_SHIFT 0x0004 Either SHIFT key must be held down.
MOD_WIN 0x0008 Either WINDOWS key was held down. These keys are labeled with the Windows logo. Keyboard shortcuts
that involve the WINDOWS key are reserved for use by the operating system
これがあなたのプログラムの実例です。
