Part IV: Communicating with Your Users
Figure 15-8 shows the result of running this procedure. The message box displays
the filenames that were selected.
Figure 15-8:
Select
multiple
filenames
by using the
GetOpen-
Filename
method.
Notice that I use a named argument for the GetOpenFilename method. I also
set the MultiSelect argument to True. The other arguments are omitted, so
they take on their default values. Using named arguments eliminates the need
to specify arguments that aren’t used.
The FileNames variable is defined as a Variant data type. I use the IsArray
function to determine whether FileName contains an array. If so, the code
uses the VBA LBound and UBound functions to determine the array’s lower
and upper bounds and build a message that consists of each array element. If
FileNames is not an array, that means the user clicked the Cancel button (the
FileNames variable contains an array even if only one file is selected).
The GetSaveAsFilename Method
The Excel GetSaveAsFilename method works just like the GetOpenFilename
method, but it displays the Excel Save As dialog box rather than its Open
dialog box. The GetSaveAsFilename method gets a path and filename from
the user but doesn’t do anything with it. It’s up to you to write code that
actually saves the file.
The syntax for this method follows:
object.GetSaveAsFilename ([InitialFilename], [FileFilter],
[FilterIndex], [Title], [ButtonText])
The GetSaveAsFilename method takes Table 15-6’s arguments, all of which
are optional.
