Hello,

Probably the world's easiest question, but I cannot locate the answer... How do you call a TempVar in Access 2007???  I.e. if I create a dropdown menu, add logic to assign the selection to a tempvar, then open a new form, how do I echo the tempvar to see if it carried through?  I've tried to create labels, etc, but I cannot assign dynamic text to them.  

Access offers to "remember the selection" for future use, but remember it as what!  This program is a little too smart for it's own good I suspect...

you can try embed the values in OpenArgs parameter of the DoCmd.OpenForm method.

Hi thanks, but the field value is assigned to a "temp var" so surely I can call it on the landing page rather than passing it?

Maybe you can store the value of "temp" into a temporary storage like a text file, xml, or in a table, so that you can retrieve that later. I don't think Access 2007 got concept of "session" as like what we usually did for web programming.

Yeah, that's what I thought.  I was thinking either session variable or passing the data as a form variable.  Then I saw this page, which lists the below code.  It basically explains how to assign global variables.  There's instructions for calling, which I can't quite figure (i.e. how can you link a label to a macros):

http://www.archivum.info/microsoft.public.access/2007-12/msg02609.html



Public Function fnTempUser(Optional TempUser As String = "") As String
 
    Static myTempUser As String
    
    If Len(TempUser) > 0 Then myTempUser = TempUser
    fnTempUser = myTempUser
    
End Function
 
--------------------------
 
To call use: Call fnTempUser("MarkMarko")

Open in new window
