是否可以使用Windows API更改VBA用户窗体标题栏的颜色。请注意，我只对更改特定用户窗体标题栏的颜色感兴趣，而不是在系统范围内更改它们。谢谢！

用户表格：

Private gHWND As Long

Private Sub Label1_MouseMove(ByVal Button As Integer, ByVal Shift As Integer, ByVal X As Single, ByVal Y As Single)
    If Button = 1 Then HandleDragMove gHWND
End Sub

Private Sub UserForm_Initialize()
    gHWND = Setup(Me)
End Sub

Private Sub UserForm_Click()
    Unload Me
End Sub
