Public Class Form1
Dim r, g, b As Integer

Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
    Timer1.Enabled = True

End Sub

Private Sub Button2_Click(sender As Object, e As EventArgs) Handles Button2.Click

End Sub

Private Sub Timer1_Tick(sender As Object, e As EventArgs) Handles Timer1.Tick
    r = 0
    g = 0
    b = 0

    For r = 1 To 225
        r += 1
        LblColor.BackColor = RGB(r, g, b)
    Next
    For g = 1 To 255
        g += 1
        LblColor.BackColor = RGB(r, g, b)

Private Function RGB(r As Integer, g As Integer, b As Integer) As Color

End Function

Private Sub LblColor_Click(sender As Object, e As EventArgs) Handles LblColor.Click

Answer 1

The RGB() function is built-in to VBA. Try removing your own version -- it's prolly getting in the way.

Private Function RGB()...  '  |   
   ...                        |    <--- remove this bit
End Function                  |

恩，所以我发现对于VB.Net，我必须使用它： LblColor.BackColor = Color.FromArgb(r, g, b) ，现在它正在工作，感谢您的帮助
