jay20018

這個問題可能簡單 但我不會w 求指點
最近學寫VB 寫了一個自動打字的 遇到一個問題
我只能點進程式視窗才可以使用快捷鍵 沒辦法下各位寫的都能在別的視窗按快捷也會動作
以下是我的程式 環境為Visual Studio2019

Public Class Form1
    Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
        Timer1.Enabled = True
    End Sub

    Private Sub Timer1_Tick(sender As Object, e As EventArgs) Handles Timer1.Tick
        SendKeys.Send((TextBox1.Text))
        SendKeys.Send("{Enter}")
    End Sub

    Private Sub Button2_Click(sender As Object, e As EventArgs) Handles Button2.Click
        Timer1.Enabled = False
    End Sub

    Private Sub TextBox2_TextChanged(sender As Object, e As EventArgs) Handles TextBox2.TextChanged
        Timer1.Interval = TextBox2.Text
    End Sub

    Private Sub Form1_KeyDown(sender As Object, e As KeyEventArgs) Handles MyBase.KeyDown
        If e.KeyCode = Keys.F1 Then
            Button1.PerformClick()
        ElseIf e.KeyCode = Keys.F2 Then
            Button2.PerformClick()
        End If
    End Sub
    Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        Me.KeyPreview = True
        Me.Enabled = True
    End Sub

End Class
