Runtime Array of Textbox Problem.

Ok so i am currently working on a magic square game and basically my form creates an 2d array, dimensions make by user(ex:2 by 2), then the form creates the number of textboxes(Ex:4) and i need to get the values in runtime to check if it is a magic square. Now i know this has something to do with addhandler so ill post my code and any help would be greatly appreciated.

Code:

---

Dim MakeArr(dbltxt - 1, dbltxt - 1)
    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        If dbltxt <= 9 Then
            Dim introw As Integer = 52
            Dim intcol As Integer = 290
            For i As Integer = 0 To dbltxt - 1
                intcol = 290
                introw += 30
                For j As Integer = 0 To dbltxt - 1
                    intcol += 40
                    MakeArr(i, j) = New TextBox
                    With MakeArr(i, j)
                        .BringToFront()
                        .Name = ("texbox" & i.ToString & j.ToString)
                        .Text = "0"
                        .Left = intcol
                        .Top = introw
                        .Width = 35
                        .Height = 25
                    End With
                    Me.Controls.Add(MakeArr(i, j))
                Next
            Next
        Else
            MessageBox.Show("Sorry the Max amount of squares is 9")
        End If
    End Sub

Take a look at this example

Code:

---

Private Sub ShowTheTime(ByVal sender As System.Object, _
              ByVal e As System.EventArgs)
          ' ----- Display the time in the text box, if it exists.
          Dim theTextBox As TextBox

          ' ----- Locate and update the text control.
          theTextBox = Me.Controls("TimeTextBox")
          If (theTextBox IsNot Nothing) Then
              theTextBox.Text = Now.ToLongTimeString( )
          End If
        End Sub

        Private Sub Form1_Load(ByVal sender As Object, _
              ByVal e As System.EventArgs) Handles Me.Load
          ' ----- Add controls at runtime.
          Dim dynamicText As TextBox = Nothing
          Dim dynamicButton As Button

          ' ----- Dynamically add a text box control to the form.
          dynamicText = New Windows.Forms.TextBox
          dynamicText.Name = "TimeTextBox"
          dynamicText.Location = New System.Drawing.Point(8, 8)
          dynamicText.Size = New System.Drawing.Size(232, 20)
          dynamicText.TabIndex = 0
          Me.Controls.Add(dynamicText)

          ' ----- Dynamically add a button control to the form.
          dynamicButton = New Windows.Forms.Button
          dynamicButton.Location = New System.Drawing.Point(144, 32)
          dynamicButton.Size = New System.Drawing.Size(99, 23)
          dynamicButton.Text = "Get Time"
          dynamicButton.UseVisualStyleBackColor = True
          dynamicButton.TabIndex = 1
          Me.Controls.Add(dynamicButton)

          ' ----- Connect the button to an event handler.
          AddHandler dynamicButton.Click, AddressOf ShowTheTime
        End Sub

how do you determine if a textbox is a magic square?

if when you add all the textboxes together diagonally, across and down they all have the same total

marius40, i do not think it works cause its a 2d array and the addhandler doesnt seem to accept array.textchanged...

I wrote the same game, a while back, i used button's and not Textboxes. Then i placed random numbers on each button, when the user click's the button, it swaps with the next button. Textboxes seems to be tricky.... well for me it was. Try buttons'.

The code i gave should work. You are trying to refer to the button as an array? This could be a problem.

Thank you for that idea but unfortunately it requires textboxes

still unresolved
