Syntax

@Prompt( [style] : [NoSort] ; title ; prompt ; defaultChoice ; choiceList ; filetype )

Parameters

[style]

Keyword. Required. Indicates the type of dialog box to display. May be any of the following:

[ChooseDatabase]

[LocalBrowse]

[Ok]

[OkCancelCombo]

[OkCancelEdit]

[OkCancelEditCombo]

[OkCancelList]

[OkCancelListMult]

[Password]

[YesNo]

[YesNoCancel]

Include the square brackets ([ ]); these identify the style parameters as keywords. If no [NoSort] keyword is provided, follow the style parameter with a semicolon (;).

[NoSort]

Keyword. Optional. Include this keyword if you want the members of

choiceList

to appear in the exact order in which you enter them. If you omit this keyword, the members of

choiceList

are sorted alphabetically.

title

Text. The text you want displayed in the dialog box's title bar. Required for all

style

s, although you can specify a null string with "". The maximum number of characters you can include in a title is 65. Provide a null string with the [ChooseDatabase] keyword; you cannot replace the default "Choose Database" title.

prompt

Text. The text you want displayed within the dialog box. Required for all

style

s, except LocalBrowse. If you use a formula for

prompt

and that formula returns a list, only the first item in the list is displayed as the

prompt

. To display the entire list, use @Implode. You can specify a field name to display the contents of the field as the

prompt

, but the field must be a text field. If it is a number or datetime field, precede it with @Text. @NewLine cannot be used in

prompt

. Use

@Char(13)

to insert a carriage return. The maximum number of characters you can include in the text that displays is 255. Provide a null string for the [ChooseDatabase] keyword; you cannot display custom text in the Choose Database dialog box.

defaultChoice

Text. The value that will be used as the default value for the user's input. The input section of the dialog box is primed with the value; the user can either accept it by clicking OK or replace it with another value. Not applicable to dialog boxes of

style

[Ok], [YesNo], [YesNoCancel], [LocalBrowse], or [Password]. Required for all other

style

s. For [OkCancelListMult], you can specify multiple default values as a text list "item1":"item2."

choiceList

Text list. The values that you want displayed in the dialog box's list box. The user can select one of these values as the input. Separate the values with colons, as in: "PHONE.NSF":@MailDbName. Each value in your list can be a text string, or an @function that returns a text string. Required only with

style

s [OkCancelList], [OkCancelCombo], [OkCancelEditCombo], and [OkCancelListMult].

filetype

Text. A value that specifies the types of files to display initially: "1" for NSF files only; "2" for NTF files only; "3" for files of all type. Required only with style [LocalBrowse].

Return value

choice

If the user enters a value, returns the value as text or a text list.
If the user selects Yes, returns 1 (True).
If the user selects No, returns 0 (False).
If the user selects Cancel, formula evaluation stops. The exception is [YesNoCancel], which returns -1 if the user selects Cancel.
@Prompt([OkCancelEdit]) returns only the first 254 characters of the text entered.

Usage

Use @Prompt in field formula, toolbar button, manual agent, form action, and view action formulas. This function does not work in column, selection, mail agent, or scheduled agent formulas, and has limited usefulness in window title and form formulas.

The title and prompt parameters are scalar. If you enter a list, only the first element displays. Use @Implode to convert the list to a string.

You cannot use this function in Web applications.
