1. Win32 problems
Hi everyone,
I've been trying to create a game in Win32 and it's almost finished, but I've
been having some problems:
1. About once every four or five times, the program crashes with the message
"The instruction at bff64e46 referenced memory at ffffffff - The memory could
not be read from" as soon as it starts (before showing the game window). I
don't know what I can do to solve this, it's really annoying me. Does anyone
know what is happening? I may post the code if it is needed.
2. How can I create a window without the title bar (like WinAmp and other
programs)? My game would look better...
I'm using Win32Lib to create this game.
Regards and happy holidays if I don't post anything else till Christmas,

PS. About the encryption thread: I know I'm late again, when I read the latest
messages about that subject I tought about writing some other unimportant
comments, but it seems like it's finished now... anyway, I think EuServer's
encryption is already strong.

you have coded a "programming oversight" as an undocumented feature
into your game. :)
also, it could be a bug in the version of win32lib.ew you are using as
well.
either way, it's bug hunt time, so break out the Raid...
if you can segregate the code into code that does work and code
that isn't working, and post the for sure broken code, i would think
that some of us may be willing to take a gander and see if we can
spot the pesky critter...

i may be trying/attempting the same thing myself, and if i figure it
out, i'll let you know, and if you figure it out, let me know... k?

As Hawke suggested, try to isolate the instruction(s) that cause the error.
I'll be glad to take a look at the code, especially if you can narrow it
down a bit.

Use the last parameter in the create() function. For controls, this value is
cumulative (they add on to whatever flags are already set), but for windows,
they replace the default values.
The flags that control the window styles start with WS_; you might try
WS_POPUP. You can also add (or or_all) several attributes together.
I may eventually define a number of default window styles for portability
between Win32Lib/Dos32Lib.

that worked like a champ! :)
not only that, it didn't make an entry in my taskbar!
(which is actually what *I* wanted, but davi, you may not want that...)
(it will make it easier for me to run the server as a "process" instead
of a "window" and i will thusly be able to start it 'hidden' with only
a tray icon... the eventual goal of the gui for EUServer(etc) )
thankee david! :)

I believe the error in my program is because I am creating the menus
immediately after creating the window. Here's what I did:
constant MainWindow =
create( Window, "The name of the game", 0, Default, Default,
64*length(GameToPlay)+2, high*64 + 64,
constant
-- Create menus
File_Menu=create(Menu,"&File",MainWindow,0,0,0,0,0),
File_NewGame=create(MenuItem,"&New game",File_Menu,0,0,0,0,0),
File_Hint=create(MenuItem,"&Hint",File_Menu,0,0,0,0,0),
File_Exit=create(MenuItem,"E&xit",File_Menu,0,0,0,0,0),
Help_Menu=create(Menu,"&Help",MainWindow,0,0,0,0,0),
Help_HowToPlay=create(MenuItem,"How to &play",Help_Menu,0,0,0,0,0),
Help_About=create(MenuItem,"A&bout",Help_Menu,0,0,0,0,0)
-- Create Text Box
constant TextBox =
When I removed all references to menus in my program (so it doesn't create
them any more) the problem seems to have disappeared. I ran it about... don't
know, 50 times, maybe more... and it didn't crash a single time. When I ran
the old one, it crashed sometimes.
What do you think, is this the problem? I could change the code to create the
menus after the window is loaded, but I don't feel like doing so unless it's
necessary...
Changing the subject a little, I use setEnable to enable/disable a menu item.
I found a very strange thing (at least for me): when I use
setEnable(File_Hint,MF_DISABLED)
the item becomes enabled and when I use
setEnable(File_Hint,MF_ENABLED)
it becomes disabled! Is it really supposed to be like that?

I suspect the problem has to do with the bug fix I posted the other day.
Could you make the correction to create() and see if that takes care of it?

setEnable expects a truth value (0 or non-zero), not MF_ENABLED or
MF_DISABLED.
Hope this helps!

I had already done it and it didn't work. Anyway, I think the bug fix was
necessary to avoid another problem with the game (I use many scroll bars in
the configuration program and such). That's why I included win32lib.e with the
game.

Thanks, now I see it. I will correct this soon in the game. I should have
thought of that in the first place...
>Hope this helps!
It sure did! Sorry for not replying earlier, I hadn't seen your message in the
listserv page...

Win32Lib and Dos32Lib are in a constant state of flux; code that runs in one
version quite often breaks in the next. I'd suggest *always* including the
version of the libraries you are coding to.
You might want to offer an EXE only version of your program for people who
run across your web pages looking for games, but don't want to bother with
downloading Euphoria.
