(wat is a PAnsiChar)
Code:
  wat := 'lolwat';
  asm
    mov eax,wat
    call ShowMessage
  end;

I took a look at how ShowMessage is called and realised that it takes the message parameter from eax, so I did the above. I just don't understand why it adds whitespace.

Top is what it does, bottom is what it's supposed to do. Can someone explain why?

Answered my own problem in second reply.

I think it's because you're suppose to change the text of the messagebox first than the title.

No, ShowMessage only has one parameter, Msg, which is a String.

And, that just happened to be my stupid mistake; I thought I had already tried using String instead of PAnsiChar but I mustn't have, and when I tried it for what I thought was the second time, it worked fine. Surprised
