Question

我有这个程序，当我在表单上键入相同的文本和另一个表单时，会在我的上一个表单的标签上添加一个（+1）..没有错误但是当我写了正确的答案时文本框它只给了我1号而不是10号。请帮助我们。在此先感谢：）

这是我的代码：

 Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

    frm4 = New Form4()
    frm1 = New Form1()
    Dim Textbox1 As New TextBox
    Dim Label3 As New Label
    If Textbox1.Text = frm1.TextBox2.Text Then
        frm4.Label3.Text = (frm4.Label3.Text) + 1
        If TextBox2.Text = frm1.TextBox4.Text Then
            frm4.Label3.Text = (frm4.Label3.Text) + 1
            If TextBox3.Text = frm1.TextBox6.Text Then
                frm4.Label3.Text = (frm4.Label3.Text) + 1
                If TextBox4.Text = frm1.TextBox8.Text Then
                    frm4.Label3.Text = (frm4.Label3.Text) + 1
                    If TextBox5.Text = frm1.TextBox10.Text Then
                        frm4.Label3.Text = (frm4.Label3.Text) + 1
                        If TextBox6.Text = frm1.TextBox12.Text Then
                            frm4.Label3.Text = (frm4.Label3.Text) + 1
                            If TextBox7.Text = frm1.TextBox14.Text Then
                                frm4.Label3.Text = (frm4.Label3.Text) + 1
                                If TextBox8.Text = frm1.TextBox16.Text Then
                                    frm4.Label3.Text = (frm4.Label3.Text) + 1
                                    If TextBox9.Text = frm1.TextBox18.Text Then
                                        frm4.Label3.Text = (frm4.Label3.Text) + 1
                                        If TextBox10.Text = frm1.TextBox20.Text Then
                                            frm4.Label3.Text = (frm4.Label3.Text) + 1
                                        End If
                                    End If
                                End If
                            End If
                        End If
                    End If
                End If
            End If






        End If
        frm4.Show()

    Else
        frm4.Label3.Text = frm4.Label3.Text

        frm4.Show()
    End If

End Sub

表单3代码:(实例调用form1）

Public Class Form3
Private frm3 As Form3
Private frm1 As Form1
Private frm4 As Form4

Public Sub New1(ByVal callerInstance As Form1)

    ' Call required if you add your constructor manually
    InitializeComponent()

    ' save the instance of the Me variable passed to this constructor
    frm1 = callerInstance
End Sub

Answer 1

如果您希望在正确答案的标签号中显示，那么您需要将所有用户答案与正确的答案进行比较并计算答案相同的时间：

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
frm4 = New Form4()
frm1 = New Form1()
Dim Textbox1 As New TextBox
Dim Label3 As New Label
Dim sameQnt As Int32 = 0

If Textbox1.Text = frm1.TextBox2.Text Then sameQnt += 1
If Textbox2.Text = frm1.TextBox4.Text Then sameQnt += 1
If Textbox3.Text = frm1.TextBox6.Text Then sameQnt += 1
If Textbox4.Text = frm1.TextBox8.Text Then sameQnt += 1
If Textbox5.Text = frm1.TextBox10.Text Then sameQnt += 1
If Textbox6.Text = frm1.TextBox12.Text Then sameQnt += 1
If Textbox7.Text = frm1.TextBox14.Text Then sameQnt += 1
If Textbox8.Text = frm1.TextBox16.Text Then sameQnt += 1
If Textbox9.Text = frm1.TextBox18.Text Then sameQnt += 1
If Textbox10.Text = frm1.TextBox20.Text Then sameQnt += 1

'Print reslut
frm4.Label3.Text = sameQnt.ToString()
frm4.Show()
End Sub

这是我的新答案

Public Class MainForm '<----Your main form class name

    Dim frm4 = New Form4()'<----declare it here
    Dim frm1 = New Form1()'<----declare it here

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

        Dim Textbox1 As New TextBox
        Dim Label3 As New Label

        Dim i As Integer = 0
        If Textbox1.Text = frm1.TextBox2.Text Then i += 1 'frm4.Label3.Text = (frm4.Label3.Text) + 1
        If TextBox2.Text = frm1.TextBox4.Text Then i += 1 'frm4.Label3.Text = (frm4.Label3.Text) + 1
        If TextBox3.Text = frm1.TextBox6.Text Then i += 1 'frm4.Label3.Text = (frm4.Label3.Text) + 1
        If TextBox4.Text = frm1.TextBox8.Text Then i += 1 'frm4.Label3.Text = (frm4.Label3.Text) + 1
        If TextBox5.Text = frm1.TextBox10.Text Then i += 1 'frm4.Label3.Text = (frm4.Label3.Text) + 1
        If TextBox6.Text = frm1.TextBox12.Text Then i += 1 'frm4.Label3.Text = (frm4.Label3.Text) + 1
        If TextBox7.Text = frm1.TextBox14.Text Then i += 1 'frm4.Label3.Text = (frm4.Label3.Text) + 1
        If TextBox8.Text = frm1.TextBox16.Text Then i += 1 'frm4.Label3.Text = (frm4.Label3.Text) + 1
        If TextBox9.Text = frm1.TextBox18.Text Then i += 1 'frm4.Label3.Text = (frm4.Label3.Text) + 1
        If TextBox10.Text = frm1.TextBox20.Text Then i += 1 'frm4.Label3.Text = (frm4.Label3.Text) + 1

        frm4.Label3.Text = i.ToString()

        frm4.Show()

    End Sub

End Class
