Question

我有一个ToolStripTextBox（它的名字是SearchBox），我想在用户输入内容并按下输入后将它们带到URL。我已经整理了URL部分，但我需要知道

之后的内容

Handles SearchBox.{what?}

当用户按下“输入”时，我在intellisense弹出窗口中看不到任何事件。

因此，换句话说，如何在用户按Enter键后执行操作？

    Private Sub ToolStripComboBox1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles SearchBox.**?????**

    Dim SearchString As String
    SearchString = SearchBox.Text

    Dim URL As String
    URL = ("https://www.example.com/search.php?&q=" + SearchString)

    Process.Start(URL)
End Sub

eliminate the enter key after pressing it in the keyup event of a textbox

不确切，但有帮助。

    Public Sub SearchBox_KeyPress(ByVal sender As Object, ByVal e As KeyEventArgs) Handles SearchBox.KeyDown

    If e.KeyCode = Keys.Enter Then

        Dim SearchString As String
        SearchString = SearchBox.Text

        Dim URL As String
        URL = ("https://www.example.com/search.php?search=" + SearchString)

        Process.Start(URL)

    End If
End Sub

您可以处理SearchBox_KeyUp或SearchBox_KeyPress事件。

这是我的代码，按任意键会导致URL加载！

    Public Sub SearchBox_KeyPress(ByVal sender As Object, ByVal e As KeyPressEventArgs) Handles SearchBox.KeyPress

        Dim messageBoxVB As New System.Text.StringBuilder()
        messageBoxVB.AppendFormat("{0} = {1}", "Enter", e.KeyChar)
        messageBoxVB.AppendLine()


        Dim SearchString As String
        SearchString = SearchBox.Text

        Dim URL As String
        URL = ("https://www.example.com/search.php?search=" + SearchString)

        Process.Start(URL)
    End Sub
End Class
