Refresh Method Example

This example uses the Refresh method to update a FileListBox control as test files are created. To try this example, paste the code into the Declarations section of a form with a FileListBox control named File1, and then run the example and click the form.

  Private Sub Form_Click ()
   ' Declare variables.
   Dim FilName, Msg as String, I as Integer
   File1.Pattern = "TestFile.*"   ' Set file pattern.
   For I = 1 To 8   ' Do eight times.
      FilName = "TESTFILE." & I
      ' Create empty file.
      Open FilName For Output As FreeFile
      File1.Refresh   ' Refresh file list box.
      Close   ' Close file.
   Next I
   Msg = "Choose OK to remove the created test files."
   MsgBox Msg   ' Display message.
   Kill "TESTFILE.*"   ' Remove test files.
   File1.Refresh   ' Update file list box.
End Sub
