Прозрачность окна и кнопки

[Мутаген]

Создаем проект Visual Basic, на форму кидаем кнопку и пишем код в эту форму:

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()
Dim Ret As Long
Ret = GetWindowLong(hwnd, GWL_EXSTYLE)
Ret = Ret Or &H80000
SetWindowLong hwnd, (-20), Ret

SetLayeredWindowAttributes hwnd, 0, 128, 2
End Sub


И наша форма становится прозразна на 50 процентов. Теперь немножко переделываем код для кнопки:

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()
Dim Ret As Long
Ret = GetWindowLong(Command1.hwnd, GWL_EXSTYLE)
Ret = Ret Or &H80000
SetWindowLong Command1.hwnd, (-20), Ret

SetLayeredWindowAttributes Command1.hwnd, 0, 128, 2 Or 1

End Sub


... и кнокпа почему то не становится на 50% прозрачнее :o Где ошибка?

Всю голову уже сломал - пробовал вместо hwnd писать идентификатор hDC для кнопки функцией GetWindowDC - то же не выходит... :shout: :shout: :shout: Пните меня в правильное направление :cry:
