I have this program that when I typed the same text on the form and to the other form will add one (+1) to the label of my last form..There were no errors but when I wrote the correct answers on the textboxes it just gave me a number 1 instead of 10. Please help me guys. Thanks in advance :)
here is my code:
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
Form 2 codes:
