Question

所以我故意尝试使用Visual Basic 2013 Ultimate制作下载ETA计算器..但是经过3个小时的工作后，我尝试运行它，但它不会显示最终结果（估计时间））。我也问你如何将结果转换为时间格式.. 这是代码

Public Class Form1

Private Property z As Object

Private Sub Label1_Click(sender As Object, e As EventArgs)

End Sub

Private Sub Button2_Click(sender As Object, e As EventArgs)

End Sub

Private Sub LinkLabel1_LinkClicked(sender As Object, e As 
            LinkLabelLinkClickedEventArgs) Handles LinkLabel1.LinkClicked
    Process.Start("www.speedtest.net")
End Sub

Private Sub Button1_Click(sender As Object, e As EventArgs) 
                          Handles Button1.Click
    Dim x, y, z, a As Integer
    Dim sum

    x = TextBox1.Text
    y = TextBox2.Text
    sum = Label1

    If RadioButton1.Checked = True And RadioButton3.Checked = True Then
        z = x / 1024 / y
        a = z / 60
        sum = a / 60
    End If

    If RadioButton1.Checked = True And RadioButton4.Checked = True Then
        z = x / 1024 / y
        a = z / 60 * 1024
        sum = a / 60
    End If
    If RadioButton2.Checked = True And RadioButton3.Checked = True Then
        z = x / 1048576 / y
        a = z / 60
        sum = a / 60
    End If
    If RadioButton2.Checked = True And RadioButton4.Checked = True Then
        z = x / 1048576 / y
        a = z / 60 * 1024
        sum = a / 60
    End If
End Sub

Private Sub RadioButton1_CheckedChanged(sender As Object, e As EventArgs) 
                                        Handles                                                  
                                        RadioButton1.CheckedChanged

End Sub
End Class

Answer 1

Dim sum
sum = Label1

据推测，Label1是一个标签控件，因此您要将变量设置为等于标签控件。

稍后，您尝试将此标签控件类型的变量设置为小数

sum = a / 60

我想说你想要替换你所有的

sum = a / 60

类似

label1.Text = New TimeSpan(a / 60, 0, 0).ToString()

并忘记变量总和

标签文本保持不变
