我如何定位在运行时创建的图片框之一？网络

Question

所以基本上，我已经成功地随机化网格中的某些图片框来包含地雷，并显示我的地雷，并且出于测试目的，这些地雷当前正在显示。你认为我需要做什么才能说：

如果你点击这个框并且我的 = 1（有一个地雷），那么你就输了。
否则，继续。

很简单，但我想将其应用于所有盒子，无论网格有多大。 (ZonesX * Zones Y)

我得到的最远的是当单击其中任何一个时将弹出一个 MsgBox() 。

这都是在运行时创建的。这是我的代码。

Public Class Form1
Inherits System.Windows.Forms.Form

Dim images(8) As Image 'declares image array

Dim zonesY As Integer = 10
Dim zonesX As Integer = 10

Dim Guy As Object
Dim pbxNewZone As PictureBox = DirectCast(Guy, PictureBox)  'declares pbxNewZone as a picturebox variable

Dim generator As New Random

Public Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

    images(0) = Image.FromFile("blank.png")
    images(1) = Image.FromFile("1.png")
    images(2) = Image.FromFile("2.png")
    images(3) = Image.FromFile("3.png")
    images(4) = Image.FromFile("4.png")
    images(5) = Image.FromFile("5.png")
    images(6) = Image.FromFile("clear.png")
    images(7) = Image.FromFile("hit.png")
    images(8) = Image.FromFile("mine.png")

    Dim x As Integer  'declares x as an integer variable
    Dim y As Integer  'declares y as an integer variable
    Me.SuspendLayout()  'suspends creation of layout

    For y = 1 To zonesY 'starts a For loop (1 to zonesY number of loops)
        For x = 1 To zonesX  'starts a For loop (1 to zonesX number of loops)
            Dim zonesize1 As Integer
            Dim zonesize2 As Integer

            pbxNewZone = New PictureBox

            Dim blockStatus As Integer
            Dim allZones As Integer
            allZones = zonesX * zonesY
            blockStatus = generator.Next(0, allZones)

            pbxNewZone.Name = y & ", " & x
            If blockStatus < (allZones / 10) Then
                pbxNewZone.Tag = True
                If pbxNewZone.Tag = True Then
                    pbxNewZone.Image = images(8)
                End If
            Else
                pbxNewZone.Tag = False
                If pbxNewZone.Tag = False Then
                    pbxNewZone.Image = images(0)
                End If
            End If
            pbxNewZone.Height = 16
            pbxNewZone.Width = 16
            pbxNewZone.Tag = 0
            zonesize1 = pbxNewZone.Height 'sets out all of the boxes on the form.
            zonesize2 = pbxNewZone.Width
            pbxNewZone.Left = ((x - 1) * zonesize1 + 15)
            pbxNewZone.Top = ((y - 1) * zonesize2 + 15)
            Me.Controls.Add(pbxNewZone)
            '  Wire this control up to an appropriate event handler
            AddHandler pbxNewZone.Click, AddressOf pbxNewZoneClicked

        Next
    Next
    Me.Height = (pbxNewZone.Height * zonesY + 63)  'sets the height of fmmGame
    Me.Width = (pbxNewZone.Width * zonesX + 40)  'sets the width of frmGame

End Sub

Private Sub pbxNewZoneClicked(ByVal sender As System.Object, ByVal e As System.EventArgs)

    Dim pb As PictureBox = DirectCast(sender, PictureBox)
    Dim pbTag As Boolean = DirectCast(sender, Boolean)

        If pb.Tag = True Then
            pb.Image = images(7) 'Hit Image
        Else
            pb.Image = images(6) 'Clear Image
        End If

    MsgBox(pb.Tag)

End Sub
End Class

Answer 1

一种快速的方法是使用 PictureBox 的 Tag 元素来跟踪是否有地雷（或任何其他条件）。

pbxnewzone.Tag = 1   'can assign tags to all of your pictureboxes in a loop or at random if need be

然后，通过将 pbxNewZoneClicked 方法的 sender 参数强制转换回 PictureBox 来访问 Tag 属性：

Dim pb As PictureBox = DirectCast(sender, PictureBox)
If (pb.Tag = 1) Then
    'change game accordingly
End If

Answer 2

除非我遗漏了某些内容，否则请设置minePictureBox1.Tag = true，然后在单击事件上检查它。或者你可以将其设置为 1 或其他值。标签是一个对象。

这就是您要找的吗？只是一个方法来知道它是否是一个地雷？

Answer 3

我认为整个网格的一个面板比每个单元格的图片框更容易管理，并且占用的资源更少。

但对于您的点击问题：

Private Sub pbxNewZoneClicked(ByVal sender As Object, ByVal e As EventArgs)
  With DirectCast(sender, PictureBox)
    MsgBox(.Name)
  End With
End Sub
