[vb6] Correct use of the Dir function

The Visual Basic Dir function is used to test if a certain file exists in a given directory. The Help topic in VB for the function states the function declaration: Dir[(pathname[, attributes])] The help topic incorrectly states that if the "attributes" parameter is omitted, all files are returned that match "pathname". In fact, if a file is flagged as Hidden, it will not be found by the Dir function, when no attributes are supplied to the function. Correct search for all files irrespective of their flags is therefore: Dir(pathname, vbNormal Or vbHidden Or vbSystem Or vbReadOnly)
