ACC97: No Match Results in FileSearch When Adding FileType

• Microsoft Access 97

SYMPTOMS

Advanced: Requires expert coding, interoperability, and multiuser skills.

When you search for file extensions using the FileType property of the FileSearch object, certain file extensions may return a "files found = 0" message even though the information does exist.

For example, this behavior occurs if you search for information on any of the following file extensions:

• SYS
• DLL
• VXD
• 386
• DRV

CAUSE

When you search for files that are hidden by default by Windows, they are excluded from indexing and content searching if the FileType property is included.

RESOLUTION

Do not include the FileType property if the file extension is not normally found in the Files Of Type box in the File Open dialog box.

STATUS

This behavior is by design.

Steps to Reproduce Behavior

1. Create a module and type the following line in the Declarations section if it is not already there:

         Option Explicit
   

2. Type the following procedure:

         Sub TestSearch()
            Dim objFS As Object
   
            Set objFS = Application.FileSearch
   
            With objFS
   
               '  Resets all the search criteria settings to their default
               '  settings.
               .NewSearch
   
               '  Where to search in Windows 95. For Windows NT 4.0, change
               '  the path to "C:\Winnt\System32\".
               .LookIn = "C:\"
   
               '  This will limit the search.
               .FileType = msoFileTypeAllFiles
   
               .FileName = "*.SYS"
   
               '  Search for "WinDir" within a file. This string is present
               '  in the file, MSDOS.SYS, in Windows 95. For Windows NT 4.0,
               '  change to "Invalid."
               .TextOrProperty = "WinDir"
   
               '  Limit the search to the root.
               .SearchSubFolders = False
   
               '  Begin the search.
               .Execute
           End With
   
            ' Show the number of files found.
            MsgBox "Files found = " & objFS.FoundFiles.Count
   
         End Sub
   
   

3. To test this function, type the following line in the Debug window, and then press ENTER:

         TestSearch
   

   Note that the message box opens and displays the following message:

         Files found = 0
   

4. Comment out the following line of code by placing an apostrophe (') in front of the line:

         .FileType = msoFileTypeAllFiles
   

5. Rerun the procedure.

   Note that the message box displays the correct count for the files that contain the search string.
