摘要：
实现代码为：
Option Explicit
Private Sub Form_Load() Label1(0).Visible = False Dim mytop As Integer, myleft As IntegerDim i As Integer, j As Integer, k As Integer mytop = 0 For i = 1 To 8 myleft = 0 For j = 1 To 8 k = (i - 1) * 8 + j Load Label1(k) Label1(k).BackColor = IIf((i + j) Mod 2 = 0, vbWhite, vbBlack) Label1(k).Visible = True Label1(k).Caption = "" Label1(k).Top = mytop Label1(k).Left = myleft myleft = myleft + Label1(0).Width Next j mytop = mytop + Label1(0).Height Next iEnd SubPrivate Sub Label1_Click(Index As Integer) Dim i As Integer, j As Integer, k As Integer Label1(Index).Caption = Index For i = 1 To 8 ......
