Greetings once again.
Can anyone translate the following into vbscript?
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
Private Const CCDEVICENAME = 32
Private Const CCFORMNAME = 32
Private Const DM_BITSPERPEL = &H60000
Private Const DM_PELSWIDTH = &H80000
Private 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
' Inputs:Dim RetValue As Integer
RetValue = ChangeRes(800, 600, 32)
'
' Returns:1 = Resolution Successfully Ch

0 = Resolution Was Not Changed
Function ChangeRes(Width As Single, Height As Single, BPP As Integer) As Integer
On Error GoTo ERROR_HANDLER
Dim DevM As DEVMODE, I As Integer, ReturnVal As Boolean, _
RetValue, OldWidth As Single, OldHeight As Single, _
OldBPP As Integer
Call EnumDisplaySettings(0&, -1, DevM)
OldWidth = DevM.dmPelsWidth
OldHeight = DevM.dmPelsHeight
OldBPP = DevM.dmBitsPerPel
I = 0
Do
ReturnVal = EnumDisplaySettings(0&, I, DevM)
I = I + 1
Loop Until (ReturnVal = False)
DevM.dmFields = DM_PELSWIDTH Or DM_PELSHEIGHT Or DM_BITSPERPEL
DevM.dmPelsWidth = Width
DevM.dmPelsHeight = Height
DevM.dmBitsPerPel = BPP
Call ChangeDisplaySettings(DevM, 1)
RetValue = MsgBox("Do You Wish To Keep Your Screen Resolution To " & Width & "x" & Height & " - " & BPP & " BPP?", vbQuestion + vbOKCancel, "Change Resolution Confirm:")
If RetValue = vbCancel Then

DevM.dmBitsPerPel = OldBPP
Call ChangeDisplaySettings(DevM, 1)
MsgBox "Old Resolution(" & OldWidth & " x " & OldHeight & ", " & OldBPP & " Bit) Successfully Restored!", vbInformation + vbOKOnly, "Resolution Confirm:"
ChangeRes = 0
Else
ChangeRes = 1
End If
Exit Function
ERROR_HANDLER:
ChangeRes = 0
End Function

I understand now that the language is Visual Basic.
Pure vbscript to change the display resolution seems not
possible.
Maybe you can use the next info

WSH has no build in functionality for this. MultiRes may do what you want. Its a
screen resolutions utility that can be used from the command line, a shortcut or
a script :-)
MultiRes (50kb) is a 32-bit alternative to QuickRes, which adds refresh rate and
multi- monitor support, as well as optional timed confirmation prompts. The
little utility supports Windows 9x/Me/NT4, as well as Windows 2000 and XP
It's available at http://168.144.101.149/files/multires.exe (Entech Taiwan), and
can be used to set screen resolution, color depth, and refresh rate. Normally it
runs with an icon in the notification area. But it's also possible to run it in
non-resident command mode in a batch file. There's more info in that at
http://www.entechtaiwan.com/multires.htm
So, you can use it to set startup resolutions by creating a simple, 1 line,
batch file and placing it in each user's startup profile.
e.g. two command lines:
User 1 - runs at 800x600, 32-bit color, 85Hz refresh
d:\multires\multires.exe /800,600,32,85 /exit
User 2 - runs at 1024x768, 32-bit color, 90Hz refresh
d:\multires\multires.exe /1024,768,32,90 /exit
