在一個窗體中的文本框和標籤，並以另一種形式訪問它

Question

我試圖訪問StudentRegistration窗體中的3個文本框和1個標籤。
我通過一個模塊聲明它爲公衆。

Module StudentInfo 

Public student_no As String = StudentRegistration.lblstudentno.Text 
Public lastname As String = StudentRegistration.txtlastname.Text 
Public firstname As String = StudentRegistration.txtfirstname.Text 
Public middlename As String = StudentRegistration.txtmiddlename.Text 

End Module 

我試圖訪問它到另一個窗體，但它不能自動顯示當我加載窗體。
你能幫我嗎？

Private Sub Payment_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load 

student_no = lblstudentno.Text 
lastname = lbllastname.Text 
firstname = lblfirstname.Text 
middlename = lblfirstname.Text 

End Sub

我試圖重現上面的代碼在Visual Basic中，假設 「付款」 的形式包含名爲lblstudentno，lbllastname，lblfirstname和lblmiddlename四個標籤分別爲（不再lblfirstname ...）。我不反對使用具有模塊級範圍的變量。我同意「OneFineDay」，變量和它們各自的值應該以「付款」形式反過來寫。像下面...

Private Sub Payment_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load 

    lblstudentn.Text = student_no 
    lbllastname.Text = lastname 
    lblfirstname.Text = firstname 
    lblmiddlename.Text = middlename 

End Sub 

此外，我想提一提的是，student_no，姓氏等值改變僅在第一次我寫的文本框裏面的一些文本「StudentRegistration」的形式。相反，在初始化StudentInfo「模塊」的變量，我建議剛聲明的變量在模塊中如下...

Module StudentInfo 

    Public student_no As String 
    Public lastname As String 
    Public firstname As String 
    Public middlename As String 

End Module 

......然後，在一些事件「付款」的形式加載之前，更新變量的值。

Public Class StudentRegistration 

    Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click 
     student_no = lblstudentno.Text 
     lastname = txtlastname.Text 
     firstname = txtfirstname.Text 
     middlename = txtmiddlename.Text 
     Payment.Show() 
    End Sub 
End Class 

我不確定它是否能在vb.net中運行，但我希望我的意見是有用的！
