Private Declare Function FindWindowA& Lib "User32" (ByVal lpClassName$, ByVal lpWindowName$)
Private Declare Function EnableWindow& Lib "User32" (ByVal hWnd&, ByVal bEnable&)
Private Declare Function GetWindowLongA& Lib "User32" (ByVal hWnd&, ByVal nIndex&)
Private Declare Function SetWindowLongA& Lib "User32" (ByVal hWnd&, ByVal nIndex&, ByVal dwNewLong&)

Private Sub UserForm_Activate()
EnableWindow FindWindowA("XLMAIN", Application.Caption), 1
End Sub

Private Sub UserForm_Initialize()
Dim hWnd As Long
hWnd = FindWindowA(vbNullString, Me.Caption)
SetWindowLongA hWnd, -16, GetWindowLongA(hWnd, -16) Or &H20000
