12/5 VB不重複隨機變數+C#變數未完

[VB] 建置9格數字經由按鈕觸發打亂數字

Private Sub CommandButton1_Click()

For i = 1 To 9
Cells(1, i).Font.ColorIndex = 0
Cells(1, i) = i

Next

For i = 1 To 9
j = 10 - i

rnd1 = (Fix(Rnd * j) + 1)
front1 = Cells(1, rnd1)
Cells(1, rnd1) = Cells(1, j)
Cells(1, j) = front1

'Cells(3, 1) = rnd1
'Cells(1, rnd1).Font.ColorIndex = 3
Next

End Sub
