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

Private Declare Function SetLayeredWindowAttributes Lib "user32" (ByVal hwnd As Long, ByVal crKey As Long, ByVal bAlpha As Byte, ByVal dwFlags As Long) As Long

Private Sub Form_Load()

Me.BackColor = &HF0000

Dim r As Long

BorderStyler = 0

r = GetWindowLong(hwnd, -20)

r = r Or &H80000

SetWindowLong hwnd, -20, r

SetLayeredWindowAttributes hwnd, &HFF0000, 0, &H1
