[AccessD] Ambiguous Name

By definition, that's a class variable not a global.

Steve,

  I should have said that this code exists in a standard module. objcurDB
has been declared private to limit the scope to the module, but it's still a
global variable, which could be accessed by any procedure in that module.

Jim.

I don't see global in this example.

There is nothing wrong with using a global variable like this:

Private objcurDB As DAO.Database

Public Function CurDb(Optional bolRefresh As Boolean = False) As
DAO.Database

 If objcurDB Is Nothing Or bolRefresh = True Then
    Set objcurDB = CurrentDb()
 End If
 
 Set CurDb = objcurDB

End Function


 And even if you did define it public, so what?  It's not like it would be
hard to spot where it's used.

Jim.

I can't agree.  Global variables break the whole model of structured  
programming.  In many ways they are worse than goto statements.

Hi Steve

Nothing wrong with global variables. 
Trouble is always located at those handling these (the programmer!).

Yet another reason to never use global variables.

Hello all,

I work with Access 2007.

Lately I ran into a problem I don't know how to solve: By running the code I
got an error message "Ambiguous Name was detected: gsngAportesSR" ("Se ha
detectado un nombre ambiguo: gsngAportesSR"). I searched the whole code
looking for gsngAportes defined by two different data types (e.g. Public
gsngAportesSR As Single, and then also Public gsngAportesSR As Integer), but
without success.

Does anyone of you know how to fix this problem?

I should say that gsngAportesSR is a global variable with data type Single.

Thanks and Saludos
