Change Caption of MessageBox with some variable inside message in Delphi

How to change the title of message dialog box with some variable inside message. I've tried 

Application.MessageBox('x * y = ' + result, 'this is title', MBICONINFORMATION);

but it shows an error said Incompatible types: 'String' and 'PAnsiChar', I know this is because the 'result' variable is not allow. Any solve? Thanks before

Solution

  • I reccomend you to use Format function as follows:

    Application.MessageBox(PChar(Format('x * y = %s', [result])), 'this is title', MB_ICONINFORMATION);
