从一种形式获取数组并在另一种形式的标签中显示内容

Question

I am working on some code that stores a user's answers into an array and compares them with another array with the correct answers in it. I have already got that part working. The part I am stuck on is having the user's answers appear in labels on another form( the exam results form ) I create an array for the labels in the other form, then make it equal to the array of user answers, but for some reason they are not displaying on the next form when i click submit.

Code:

'Display user answers on the exam result form
    Dim aUserAnswersDisplayed() As String = {frmExamResults.lblUserAnswer1.Text, frmExamResults.lblUserAnswer2.Text,
                                             frmExamResults.lblUserAnswer3.Text, frmExamResults.lblUserAnswer4.Text,
                                             frmExamResults.lblUserAnswer5.Text, frmExamResults.lblUserAnswer6.Text,
                                             frmExamResults.lblUserAnswer7.Text, frmExamResults.lblUserAnswer8.Text,
                                             frmExamResults.lblUserAnswer9.Text, frmExamResults.lblUserAnswer10.Text,
                                             frmExamResults.lblUserAnswer11.Text, frmExamResults.lblUserAnswer12.Text,
                                             frmExamResults.lblUserAnswer13.Text, frmExamResults.lblUserAnswer14.Text,
                                             frmExamResults.lblUserAnswer15.Text, frmExamResults.lblUserAnswer16.Text,
                                             frmExamResults.lblUserAnswer17.Text, frmExamResults.lblUserAnswer18.Text,
                                             frmExamResults.lblUserAnswer19.Text, frmExamResults.lblUserAnswer20.Text}

    For intDisplayAnswers = 0 To 19
        aUserAnswersDisplayed(intDisplayAnswers) = aUserAnswers(intDisplayAnswers)
    Next

    frmExamResults.Show()

Answer 1

Add a constructor with parameters in FrmExamsResult and pass the array in the object constructor. The other option is to define a property in the form. Once instantiated the object you can set the array in the property.

Another option is to use a singleton class where you store the array. Being singleton can be accessed from both forms.

Answer 2

Suppose you have two form Named Form1 and Form2 and you want content from Form1 displayed on Form2 . Here is the method you can use

Create a New() method on Form2

Dim _value1 as <DataType>,.......
Public Sub New(ByVal value1 as <DataType>,...........)
    `INITIALIZATION FUNCTION WILL CREATE AUTOMATICALLY`
    _value1 = value1
End Sub

Now on Form1 , call Show() or ShowDialog() method after creating and using Form2 object. This methods will show you the constructor defined in Form1 created using New() method. Pass the desired values and you will have your values on Form2 .

Dim a as Form1
a.ShowDialog(<Parameters here>)

Hope this helps..
