اخى مشكلتك مع الــــ Screen Resolution [b][/b]فقط نزل المثال وعدل على مقاس الشاشة التى يعمل عليها مشروعك ليعمل على كل الاجهزة
تحياتى لك

ضع مايلي في module

'''دقة الشاشة'''''

بعد ذلك في الفورم الابتدائي ضع التالي
Dim typDevM As typDevMODE
Dim lngResult As Long
Dim intAns As Integer
Private Sub Form_Load()
' تخزين دقة الشاشة
intWidth = Screen.Width \ Screen.TwipsPerPixelX
intHeight = Screen.Height \ Screen.TwipsPerPixelY
' تغيير دقة الشاشة
lngResult = EnumDisplaySettings(0, 0, typDevM)

With typDevM
.dmFields = DM_PELSWIDTH Or DM_PELSHEIGHT
.dmPelsWidth = 1024 'اختر العرض (640,800,1024, etc)
.dmPelsHeight = 768 'اختر الطول (480,600,768, etc)
End With

lngResult = ChangeDisplaySettings(typDevM, CDS_TEST)
Select Case lngResult
Case DISP_CHANGE_RESTART
intAns = MsgBox( _
"You must restart your computer to apply these changes." & vbCrLf & _
vbCrLf & "Do you want to restart now?", vbYesNo + vbSystemModal, _
"Screen Resolution")
If intAns = vbYes Then Call ExitWindowsEx(EWX_REBOOT, 0)
Case DISP_CHANGE_SUCCESSFUL
Call ChangeDisplaySettings(typDevM, CDS_UPDATEREGISTRY)
' MsgBox "تم تغيير اعدادات الشاشة الى 1024*768", vbInformation, _
' "تنبيه"
Case Else
MsgBox "Mode not supported", vbSystemModal, "Error"
End Select
End Sub

في ازرار الخروج ضع

Private Sub ALL2_Click()
lngResult = EnumDisplaySettings(0, 0, typDevM)
With typDevM
.dmFields = DM_PELSWIDTH Or DM_PELSHEIGHT
.dmPelsWidth = intWidth 'اختر العرض (640,800,1024, etc)
.dmPelsHeight = intHeight 'اختر الطول (480,600,768, etc)
End With

lngResult = ChangeDisplaySettings(typDevM, CDS_TEST)
Select Case lngResult
Case DISP_CHANGE_RESTART
intAns = MsgBox( _
"You must restart your computer to apply these changes." & vbCrLf & _
vbCrLf & "Do you want to restart now?", vbYesNo + vbSystemModal, _
"Screen Resolution")
If intAns = vbYes Then Call ExitWindowsEx(EWX_REBOOT, 0)
Case DISP_CHANGE_SUCCESSFUL
Call ChangeDisplaySettings(typDevM, CDS_UPDATEREGISTRY)
' MsgBox "تم تغيير اعدادات الشاشة الى 1024*768", vbInformation, _
' "تنبيه"
Case Else
MsgBox "Mode not supported", vbSystemModal, "Error"
End Select
End
End Sub
مع ملاحظة في كل فورم موجود ضع في قسم التصريح
Dim typDevM As typDevMODE
