Help with Delphi Console Keypress

[CodeTRUCKER]

I was looking to test out an app idea with the Delphi Console Keypress (or whatever it is) and was interested in some opinions.  The reason I want to use the "console" is because it is a game for the blind.

dont make a console application; make a form, then you can catch all the keystrokes in a nice event.

[CodeTRUCKER]

Alright, no console.  Anyone else want to chime in?

It can have a GUI.

Just be sure you close your eyes before hitting F9 in Delphi and don't open them again till you have hit alt+F4, when testing your game.

Then you will know if it is acceptable or not.

BTW - Can you tell me why any string def I use will not allow more then 255 chars?  This even happens when I declare the following...

var
      Longstring: AnsiString;

It's supposed to take 2GB, but I keep getting the error saying it can only have 255?  Weird.

When you declare a var as AnsiString in Delphi, you get the old-style statically allocated string with max length of 255. It's the same as saying
var
 myStr : string[255];

What you need is
var
 myStr : string;


Also check in Compiler options that "Huge strings" is enabled - it should be on by default, but do verify. If this define is disabled, the above declaration will still give you a 255-char string.

Thank you.  I will give it a try and get back.

[mouser]

maybe you can tell us more about the "error" you are getting, to help us help you figure out what it is.

[CodeTRUCKER]

I can't get past the 255 error.  Like I said, weird.  Frankly at this point I may have to punt and press on with my old VB5.  I know that pretty well, but I was hoping to get my feet into Delphi.  Well, maybe later I can try again.  I can't wait too long, though.  My trial license of Turbo Delphi is only good for 98 more years!   Thanks to All for the help.

Correction, I wasn't remembering clearly:

The above is wrong. Here's what really happens: when you declare a var as AnsiString, you do get the "huge" string variety. This does not depend on the "Huge strings" compiler switch, since you're explicitly asking for one. The compiler switch only affects declarations of "var s : string;"

But as mouser said, please give a bit more info on your code and the specific error.
