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 Methods.

Example

In the following example, the Dialog.Confirm method prompts the user for a true or false answer.

var
    Question: Text;
    Answer: Boolean;
    CustomerNo: Integer;
    Text000: Label 'Exit without saving changes to customer %1?';
    Text001: Label 'You selected %1.';
begin
    CustomerNo := 01121212;  
    Question := Text000;  
    Answer := Dialog.Confirm(Question, true, CustomerNo);  
    Message(Text001, Answer);  
end;

The first dialog box shows:

Exit without saving changes to customer 1121212?

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

You selected true.
