Question

基本上，我有两个int变量，x和y，我用来创建一个图片框的网格。

这一切都是流动的，并建立在运行时。

如果我的= 2，我正在尝试特别更改图片框。

我不能特别更改一个，当我单击任何一个时，它会更改所有的

请帮助! !

下面是我的代码:

  Public Class Form1
    Inherits System.Windows.Forms.Form
    Dim images(8) As Image 'declares image array
    Dim zonesY As Integer = 50
    Dim zonesX As Integer = 50
    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
                Dim mine As Integer
                pbxNewZone = New PictureBox
                Dim blockStatus As Integer
                Dim allZones As Integer
                allZones = zonesX * zonesY
                blockStatus = generator.Next(0, allZones)
                pbxNewZone.Name = (zonesX * (y - 1)) + x
                If blockStatus < (allZones / 10) Then
                    mine = 1
                    If mine = 1 Then
                        pbxNewZone.Image = images(8)
                    End If
                Else
                    mine = 2
                    If mine = 2 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
        checkBlank()
    End Sub
    Public Sub checkBlank()
    End Sub
    Private Sub pbxNewZoneClicked(ByVal sender As System.Object, ByVal e As System.EventArgs)
        ReDim x

            Do While x = 1  'starts a For loop (1 to zonesX number of loops)
                MsgBox("you have clicked " & x & ", " & y)
            Loop

Answer 1

您为所有的PictureBox添加了相同的处理程序，但没有对被单击的特定PictureBox (Sender参数)做任何事情。您可以使用Name或Tag属性来确定如何处理单击。您可能想要扩展标准的PictureBox，以包含额外的参数，使这更容易-例如x和y属性。

作为题外话，您可能需要考虑重构form_load，以便它调用一些更离散的方法。

Answer 2

在Click事件中，sender将是被点击的对象，因此…

Dim pbx as PictureBox = DirectCast(sender,PictureBox)

…会给你一个参考(如pbx)点击的PictureBox -然后你可以做你需要做的事。

为了方便，你可能想检查一个给定的PictureBox的状态通过检查pbx.Image -因为你没有任何自定义属性的PictureBox
