Só pra finalizar com Chave de Ouro.
No form principal cole
Private Sub Form_Load()
Dim intX As Integer
Dim intY As Integer
Dim strResolucao As String
intX = Screen.Width / Screen.TwipsPerPixelX
intY = Screen.Height / Screen.TwipsPerPixelY
strResolucao = intX & "x" & intY
If strResolucao <> "1024x768" Then
Res = Split(strResolucao, "x") 'Armazena a resolução em uma array
Call ChangeRes(1024, 768) 'altera a resolução para 1024x768
End If
End Sub
Private Sub Form_Unload(Cancel As Integer)
'quando você encerrar o programa
Call ChangeRes(CInt(Res(0)), CInt(Res(1))) 'Retorna para resolução padrão do PC
End Sub
