Type in (or Copy) the following code to the click event of the Command button. Open the file and click the button; you will see the display shown in the next picture. The text formatting was applied in the design mode.

Once the connection string is correctly set, the derivation of the properties, or the usage of the methods is quite simple. For most of the properties the enumerated constants are used. The enumerated constants and their values are also shown for some of the properties in the above picture. For example, RecordType=0 means it is a file, whereas RecordType=1 would imply a folder. The properties explored are highlighted in the code shown above. One of the properties which distinguishes a file from a folder is the RecordType. The RecordMode property used with records is very similar to the LockType property used with recordsets. The Fields collection refers to the various parts of the URL using an index as shown in the code. In the above example, rec.Fields(0) is the HelloOra.asmx file. In order to read the content of this field you would require a Stream object.
