CONFIRM Function (Dialog)

Creates a dialog box that prompts the user for a yes or no answer. The dialog box is centered on the screen.


Ok := Dialog.CONFIRM(String [, Default] [, Value1] ,...)  


Type: Code or text constant

Specifies the string that is displayed in the dialog box. Use a backslash (\) to indicate a new line. The string can be a text constant that is enabled for multilanguage functionality. For more information, see Multilanguage Development.

Type: Boolean

Specifies the default button. If you do not specify a default button, then No is used as the default button.

Value1, …
Type: Any

Any type of constant or C/AL variable that you want to insert into String. You can insert up to 10 values.

Property Value/Return Value

Type: Boolean

true if you entered Yes; otherwise, false.

This return parameter reflects the user's selection.


The message window is automatically sized. The height of the window corresponds to the number of lines and the width corresponds to the length of the longest line.

We recommend that you always end CONFIRM messages with a question mark. For more information about best practices for end-user messages, see Progress Windows, MESSAGE, ERROR, and CONFIRM Functions.


In the following example, the Dialog.CONFIRM function prompts the user for a Yes or No answer. This code example requires that you create the following variables.

Name DataType
Question Text
Answer Boolean
CustomerNo Integer

This code example requires that you create the following text constants in the C/AL Globals window.

Name ConstValue
Text000 Exit without saving changes to customer %1?
Text001 You selected %1.
CustomerNo := 01121212;  
Question := Text000;  
Answer := Dialog.CONFIRM(Question, TRUE, CustomerNo);  
MESSAGE(Text001, Answer);  

The first dialog box shows:

Exit without saving changes to customer 1121212?

If you select the default Yes value, then the second dialog box is shown:

You selected Yes.
