    Good evening,

    I was testing ABWifi lib, v 1.2, with the following code:

    Sub Process_Globals
    Dim lat As Double
    Dim lon As Double
    End Sub

    Sub Globals
    Dim MyWifi As ABWifi
    End Sub

    Sub Activity_Create(FirstTime As Boolean)
    Dim r As Boolean
       r = MyWifi.ABLoadWifi()
       r = MyWifi.ABGetLocation(
    If r = False Then
          r = MyWifi.GetLastKnownLocation(
    If r = False Then
    Msgbox (MyWifi.ABWifiLastError(), "")
    End If
    End If
    Msgbox ("" & lat & " - " & lon, "")
    End Sub

    Sub Activity_Resume

    End Sub

    Sub Activity_Pause (UserClosed As Boolean)
    End Sub

    Sub MyWifi_FoundLocation ()
    Dim ResLocation As ABFoundLocation
       ResLocation = MyWifi.ABGetFoundLocation()
       lat = ResLocation.Latitude
       lon = ResLocation.Longitude
    Msgbox ("" & ResLocation.Latitude & " - " & ResLocation.Longitude, "")
    End Sub
    The problem is that at some time I received the second message box with my coords right.
    But now, I'm only getting 0 - 0 values with the first message box, and the second doesn't appear.

    I really know I'm doing something wrong.

    Can someone please help me out?

    Kind regards,

    Same thing is happening with another routine... I can't seem to be able to assign the proper values to a variable that I want to be Global.
    If I declare a variable like Var1 in Sub Process_Globals, can't I change it and access it in other sub routines?

    You can change the value of a process global variable and access it from other subs or modules.

    You need to specify the module. So, if you have a module called MyModule, with the public variable MyVar, you'll have to access it with Mymodule.MyVar.
