No win 98 quando executo um script pra mudar a resolução a tela fica pela metade, já quando é executado o mesmo cod no XP o problema não ocorre. O Script é o seguinte. Código em um módulo .bas Public Type RECT Left As Long Top As Long Right As Long Bottom As Long End Type Public Declare Function GetClipCursor Lib "user32.dll" (lprc As RECT) As Long Private Declare Function EnumDisplaySettings Lib "user32" Alias _ "EnumDisplaySettingsA" (ByVal lpszDeviceName As Long, ByVal iModeNum As Long, _ lpDevMode As Any) As Boolean Private Declare Function ChangeDisplaySettings Lib "user32" Alias _ "ChangeDisplaySettingsA" (lpDevMode As Any, ByVal dwflags As Long) As Long Const CCDEVICENAME = 32 Const CCFORMNAME = 32 Const DM_PELSWIDTH = &H80000 Const DM_PELSHEIGHT = &H100000 Private Type DEVMODE dmDeviceName As String * CCDEVICENAME dmSpecVersion As Integer dmDriverVersion As Integer dmSize As Integer dmDriverExtra As Integer dmFields As Long dmOrientation As Integer dmPaperSize As Integer dmPaperLength As Integer dmPaperWidth As Integer dmScale As Integer dmCopies As Integer dmDefaultSource As Integer dmPrintQuality As Integer dmColor As Integer dmDuplex As Integer dmYResolution As Integer dmTTOption As Integer dmCollate As Integer dmFormName As String * CCFORMNAME dmUnusedPadding As Integer dmBitsPerPel As Integer dmPelsWidth As Long dmPelsHeight As Long dmDisplayFlags As Long dmDisplayFrequency As Long End Type Dim DevM As DEVMODE Public Sub ChangeRes(iWidth As Single, iHeight As Single) Dim a As Boolean Dim i As Long Do a = EnumDisplaySettings(0&, i, DevM) i = i + 1 Loop Until (a = False) Dim b As Long DevM.dmFields = DM_PELSWIDTH Or DM_PELSHEIGHT DevM.dmPelsWidth = iWidth DevM.dmPelsHeight = iHeight b = ChangeDisplaySettings(DevM, 0) End Sub Agora no Form digite o seguinte: Dim ResX As Single Dim ResY As Single Dim OldResX As Single Dim OldResY As Single Dim Resolucao As Boolean Private Sub Form_Load() ResX = 640 ResY = 480 Dim r As RECT Call GetClipCursor(r) OldResX = r.Right OldResY = r.Bottom If OldResX <> ResX And OldResY <> ResY Then Resolucao = True Call ChangeRes(ResX, ResY) Else Resolucao = False End If End Sub Private Sub Form_Unload(Cancel As Integer) If Resolucao = True Then Call ChangeRes(OldResX, OldResY) End If End Sub Se alguém puder me ajudar serei grato.... Obrigado!
