ADP Client (Local) Storage

[Anthony Headley]

Hey all, quick question,

I would like to store some local information "In" the clients ADP but I'm
not too sure of the best way to do this.

For the time being I would like to save two simple variables:

1) The last logged on user. At the moment I create a file with VBA with
the users name after a successful login.

2) The current Client ADP Version, at the moment I store this in a module
function al la
~Snip~
Function get_client_version()
get_client_version = "1.4"
End Function
~Snip~

Is there a way that I can do this in a dataset local to the ADP, without
creating an external file or registry entry that the user might be able to
fiddle with?


Thanks again.

Maybe you could use the custom properties collection, something like:

Public Sub SetProperty( _
ByVal strPropName As String, _
ByVal varPropType_Bidon As Integer, _
ByVal varPropValue As Variant)


Const cProcedureName As String = "SetProperty"
On Error GoTo Err_Handler


Dim db As CurrentProject
Set db = Application.CurrentProject


' Properties are string values.
If (IsNull(varPropValue)) Then varPropValue = ""


Dim i
For i = 0 To db.Properties.Count - 1
If (db.Properties(i).name = strPropName) Then
db.Properties(strPropName).Value = varPropValue
GoTo Exit_Sub
End If
Next


db.Properties.Add strPropName, varPropValue


Exit_Sub:
On Error GoTo 0
Set db = Nothing
Exit Sub


Err_Handler:


''''' Call LogError(Err.Number, Err.Description, cModuleName &
cProcedureName)
Resume Exit_Sub


End Sub


' GetProperty(): returns TRUE if the property was already known; FALSE
otherwise.
' The value itself is passed by argument.


Public Function GetProperty( _
ByVal strPropName As String, _
ByRef strPropValue As Variant) As Boolean


Const cProcedureName As String = "GetProperty"
On Error GoTo Err_Handler


Dim db As CurrentProject
Set db = Application.CurrentProject


Dim i
For i = 0 To db.Properties.Count - 1
If (db.Properties(i).name = strPropName) Then
strPropValue = db.Properties(strPropName)
GetProperty = True
GoTo Exit_Function
End If
Next


GetProperty = False


Exit_Function:
On Error GoTo 0
Set db = Nothing
Exit Function


Err_Handler:
GetProperty = False
''''' Call LogError(Err.Number, Err.Description, cModuleName &
cProcedureName)
Resume Exit_Function


End Function


Also, notice that unlike with MDB, the user cannot access this collection
from the menu.

Perfect. That is exactly what I was looking for. I didn't realize that the
properties collection was persistent, though that makes perfect sense.
This is a perfect solution.

While I was in my halfway point between MDB and ADP I would store local
data in native MBD tables and the real data via linked tables, so I have
never looked at the Porperty collection, but now... I code....

Thanks!
