I was finding it difficult to optimize my corporate homepage for different screen resolutions, so I created four separate framesets, each optimized to a different resolution, from 640x480 to 1280x1024.

Here is how I determined the resolution. The user32 dynamic link library has accessor functions available that allow to you efficiently retrieve that information. By putting that functionality into the homepage's database script post-open event, I am able to determine the screen resolution of the PC each time it opens the database. I am writing that value to an environment variable. Each time I open the database, via the post-open event, I am testing whether the current resolution is changed from the last time that the environment variable was written. Every time someone opens this database, the current resolution is written to this environment variable.
I created another frameset as a host to one of the four framesets mentioned above, to be determined at runtime via a computed formula based upon the dynamic value representing the screen resolution. This host is a one-frame frameset, populated with the computed value listed below. This is the database's default frameset as defined within the database properties.
Database script code:
Declarations: Type RECT x1 As Long y1 As Long x2 As Long y2 As Long End Type Declare Function GetDesktopWindow Lib "User32" () As Long Declare Function GetWindowRect Lib "User32" (Byval hWnd As Long, rectangle As Rect) As Long And within the PostOpen event: Dim session As New NotesSession currentRes = getResolution.FormLoad() tempRes = session . GetEnvironmentString("currentRes") If (tempRes <> currentRes) And (tempRes <> "") Then Messagebox "Notes has detected a change in your screen resolution. The next time you start the Corporate Intranet, the homepage will be adjusted to optimize your new resolution setting.", 0 + 64, "Screen Resolution Change" Elseif tempRes = "" And currentRes <> "800x600" Then Messagebox "Your screen resolution has been detected as " & currentRes & ". Your intranet will be optimized for this display setting and will be used the next time that you login. For this session, the default of 800x600 will be used.", 0 + 64, "Screen resolution settings" Elseif tempRes = "" And currentRes = "800x600" Then Messagebox "Your screen resolution has been detected as " & currentRes & ". This is the default resolution setting for the Corporate Intranet as well, therefore no changes need to be applied.", 0 + 64, "Screen resolution settings" End If Call session.SetEnvironmentVar ( "currentRes", currentRes ) Add this function: Function FormLoad() As String Dim workspace As New NotesUIWorkspace Dim R As Rect Dim hWnd As Long Dim RetVal As Long Dim GetScreenResolution As String hWnd = GetDesktopWindow () RetVal = GetWindowRect(hWnd, R) GetScreenResolution = (R.x2 - R.x1) & "x" & (R.y2 - R.y1) FormLoad = GetScreenResolution End Function
Finally, the code that goes within the default frameset to determine which frameset to actually display (I have named the framesets with the resolution that they represent):
temp := @Environment("currentRes"); @If(temp = "640x480";"640x480"; @If(temp = "800x600";"800x600";@If(temp = "1024x768";"1024x768";@If(temp = "1152x864";"1152x864";@If(temp = "1280x1024";"1280x1024";"800x600")))))
