ACC2000: No Match Results in FileSearch When Adding FileType

ID: Q208811

The information in this article applies to:

Microsoft Access 2000

This article applies to a Microsoft Access database (.mdb) and a Microsoft Access project (.adp).

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

SYMPTOMS

When you search for file extensions by 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

DRV

386

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. See the "Steps to Reproduce Problem" section of this article for an example of code that will search for these file types properly.

Steps to Reproduce Behavior

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


Option Explicit

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:\Windows"

      '  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

To test this function, type the following line in the Immediate window, and then press ENTER:
```
TestSearch 
```
Note that the message box opens and displays the following message:


   Files found = 0

Comment out the line of code that sets the FileType property by placing an apostrophe (') in front of the line, as follows:


' .FileType = msoFileTypeAllFiles

Rerun the procedure.

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