Can you change the color of the titlebar of a userform in VBA using Windows API?

问题

Is it possible to change the color of the title bar for a VBA userform using Windows API. Please note that I am only interested in changing the color of the title bar for a particular userform and not a system-wide them change. Thanks!

Just for fun;

UserForm:

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

*.BAS

Option Explicit
Private Const WM_NCLBUTTONDOWN = &HA1&
Private Const HTCAPTION = 2&
Private Const GWL_STYLE = (-16)
Private Const WS_BORDER = &H800000
Private Const WS_DLGFRAME = &H400000
Private Const WS_CAPTION = WS_BORDER Or WS_DLGFRAME
Private Declare Sub ReleaseCapture Lib "User32" ()
Private Declare Function SendMessage Lib "User32" Alias "SendMessageA" (ByVal HWND As Long, ByVal wMsg As Long, ByVal wParam As Long, lParam As Any) As Long
Private Declare Function FindWindow Lib "User32" Alias "FindWindowA" (ByVal lpClassName As String, ByVal lpWindowName As String) As Long
Private Declare Function GetWindowLong Lib "User32" Alias "GetWindowLongA" (ByVal HWND As Long, ByVal nIndex As Long) As Long
Private Declare Function SetWindowLong Lib "User32" Alias "SetWindowLongA" (ByVal HWND As Long, ByVal nIndex As Long, ByVal dwNewLong As Long) As Long

Function Setup(objForm As Object) As Long
    Setup = FindWindow("ThunderDFrame", objForm.Caption)
    SetWindowLong Setup, GWL_STYLE, GetWindowLong(Setup, GWL_STYLE) And Not WS_CAPTION
End Function

Public Sub HandleDragMove(HWND As Long)
    Call ReleaseCapture
    Call SendMessage(HWND, WM_NCLBUTTONDOWN, HTCAPTION, 0&)
End Sub

(Would need mod for 64bit Office)
