----------------------------------------------------------------------------------
Run Time Error 94 -- Invalid Use of Null
----------------------------------------------------------------------------------

A Run Time Error 94 (Invalid Use of Null) may occur when
searching for call sign information in some specific Canada
locations .  This search functionality is in DataSource at
the Call Sign Information tab.   

To correct this problem, copy the updated ULS.MDB to the
proper folders on your computer as explained below. 
The following steps apply to Windows XP, Windows Vista
and Windows 7 operating systems, with exceptions
as noted.

1.  Log into computer as Administrator.

2.  Some folders which need to be accessed may be "hidden"
     and therefore not immediately visible.  If this is the case they
     may be temporarily shown in order to work with them. 

     a.  From My Computer or Computer select from the menu
     
          Tools > Folder Options > View tab

     b.  In the "Files and Folders" section, there is an item for 
         "Hidden Files and Folders" in which there are two radio
          button choices under "Select to Show hidden files, folders and 
          drives", i.e.

         -- Don't show hidden files, folders, or drives
         -- Show hidden files, folders, and drives (SELECT THIS ONE)

         Select to "Show hidden files, folders, and drives"

         Further down deselect the radio button for

         -- Hide Protected Operating System Files

         and choose "Yes" at the Warning dialog.

      c.  Click the Apply button, then the OK button and close the window in use. 
           All hidden and/or system files should now be visible in the folder structure.

      d.  When finished with the following steps these settings may then be reverted.    


3.  Open the folder where TravelPlus for Repeaters Version 15
     was INSTALLED.  On most
  computers, this will be in Program Files
     at the default directory, i.e. 

        C:\Program Files\TravelPlus for Repeaters.

     Copy the new ULS.MDB file into this folder, replacing
     the previous copy of the file.




4.  Locate the folder where TravelPlus Version 15 DATA is stored.
     By default this is normally a hidden folder.  It's location depends
     upon which Windows operating system is in use. 

     On Windows XP and prior versions of Windows, this folder will be:

 

        C:\Documents and Settings\All Users\Application Data\TravelPlus Version 15

     On Windows Vista and Windows 7 this folder will be:

        C:\ProgramData\TravelPlus Version 15


5.  Copy the new ULS.MDB file into the appropriate folder above replacing
     the previous copy of the file.


 

6.  Launch the TravelPlus for Repeaters application.
    With the new version of ULS.MDB installed, the error message

    described above will no longer appear.
