MessageDlg wrong delphi type?

MessageDlg(myinfo.totret, mtInformation, [mbOK], 0, mbOK);

Open in new window


myinfo.totret is type double

I get the following error:

There is no overload version of 'MessageDlg' that can be called with these arguments. I think it's because I'm using type double instead of type string in the MessageDlg code, not sure the easiest way to convert?

Thanks,

Remove the last mbOK

Change this to
MessageDlg(FloatToStr(myinfo.totret), mtInformation, [mbOK], 0)

Perfect, thank you! This is my first attempt at a language that is strongly typed and it's presenting me some head aches, but will make my code better in the long run I suppose.

For example:
MessageDlg(format('%g', [myinfo.totret]) , mtInformation, [mbOK], 0, mbOK);
