Title says it all, but can someone explain why I can't seem to associate a string variable at runtime in the dpr to the application.title?
Everytime I put the line of code in, it disables the RUN application button, and then if I save and leave it in and try and reopen the application, it is now corrupt and I have to restart from a prvious version of the code.

I'm guessing this is just something I didn't know you couldn't do but I'm just checking.

var
  sTemp: String;
begin
  .
  .
  .
  Application.Title := 'This string'+ sTemp;

Its a "known" feature (at least to borland)/

// This is a known 'feature' and it has been there since Delphi 1. Notice I
// don't call it a bug. The reason this works like this is because we allow you
// to set the Application.Title in the IDE so we need to set it to a string.
// With a const we wouldn't know what type it was unless we did a full
// expression parse on it. It isn't worth it.
//
// -- Robert Kozak (Borland)


The workaround is to perform something similar to the following:


var
  sTemp:         String;

procedure SetTitle(App: TApplication);
begin

  App.Title:='This string'+ sTemp;

end;

begin

  Application.Initialize;
  Application.CreateForm(TForm1, Form1);
  SetTitle(Application);
  Application.Run;

end.
