R5: FileOpenDialog and Prompt methods (continued)
Using Prompt with a list of values
The next example allows the user to select from a list of values. Figure C shows that dialog in action.
FIGURE C
 
Choose your favorite player in this nice list dialog. Roll over picture for a larger image.
In this example, we again declare the variables to be used. Next, we initialize the array of selection values. Using the Prompt method, we prompt the user for the selection. Finally, a non-empty value (e.g., returnValue <> "") signals a selection was made. Let's look at that in one chunk:
Dim uiwork As New NotesUIWorkspace
Dim returnValue As String, possibleValues(5) As String
possibleValues(0) = "Julius Erving"
possibleValues(1) = "Moses Malone"
possibleValues(2) = "Charles Barkley"
possibleValues(3) = "Wilt Chamberlain"
possibleValues(4) = "Maurice Cheeks"
possibleValues(5) = "Bobby Jones"
returnValue = uiwork.Prompt(PROMPT_OKCANCELLIST,"Survey",Who was the greatest Philadelphia 76er of all time?","",possibleValues)
If (returnValue <> "") Then
Print "Your favorite player is " & returnValue
Else
Print "Sorry, but no selection was made."
End If

Conclusion
The addition of the Prompt and FileOpenDialog methods provide functionality that has been on the wish list of many developers for some time. This functionality previously required complicated workarounds with the Windows API, which is a bit too much work for something that is standard in other development environments. We're really glad to see it finally arriving in R5.
