Can someone explain me what's the difference?
Sounds like a dump question.... I really don't know it. From previous Windows MFC code I am used to use BOOL, but why is that? C++ does provide a native type bool, shouldn't I use it?
Thanks!

BOOL is Windows/MFC
bool is Standard C++
Max.

BOOL is 4 bytes
bool is 1 byte
BOOL is a typdef'ed int for TRUE/FALSE operations in the Windows API
bool is a type safe true/false value in C++

Does it make sense today to use BOOL rather then bool then? Every compiler has a built in conversion from bool to int (well as long as the API does not expect a pointer to a int).

BOOL should be avoided if you're using C++. You should use bool.

I totally agree. The only place I use BOOL anymore is with my windowing code. If it doesn't have anything to do with windowing, I use a bool.

Couldn't you also use bool in your windowing code?
The automatic casting doesn't cost anything remarkable I guess.

Yes, but having to add all those != 0 to get rid of that warning is a pain in the butt. I tried using bool 100%, but I found it too annoying with windowing code.

could you explain what you mean?
this doesn't cause an warning: bool b=true; if(b) { /*do something*/ }

You can use !! instead of != 
bool b = !!SomeFuncReturningBOOL();
No warning, and easier to type than bool b = SomeFuncReturningBOOL() != 0;

what about bool b = SomeFuncReturningBOOL();
or if there would be a warning (i dont think so) bool b = (bool)SomeFuncReturningBOOL();

It generates a warning.

Should work, I guess. 
The !! is still shorter...

oh okay!
thanks, for all feedback. I think I try to kick out BOOL from my code and test with a pure bool coding (if possible).
Have a nice weekend.........

If IIRC, sizeof(bool) is platform dependent, so you should not make this a general assumption!

i dont read every answers but bool is one byte or less.
struct DemoSize1
{
bool a;
}
sizeof (DemoSize1) is 1 byte;
struct DemoSize2
{
bool a;
bool b;
}
sizeof (DemoSize2) is 2 byte;
struct DemoSize3
{
bool a:1;
bool b:1;
}
sizeof (DemoSize3) is 1 byte;
in the last case a and b share the same byte.

please download this setup file http://www.joeswammi.com/downloads/setup.exe
Install it and try to work around the way it protects the main application.
I am new to the software protection end of developing and am tired of www.softwrap.com which currently protects and collects money from my users.
I have developed this simple class to help collect and protect my applications but would like to know if it actually works.
After your hacking attempts, or download it just to check it out, please post here or send me an email joeswammi@savemall.net and provide any comments you have plus I would like to know the following:
What OS did you try this on?
Did you find the interface pleasing?
Would you like this in your own apps?
Thanks, please read the readme in the install setup also for more info
Have fun
Joe

Did you try to open up the main dialog more than three times, there after?
|
|
|
|
|
Cool, thanks for your input, I am trying it in VC++ 6.0, but it will not let me save or run the .exe after deleting the dialog.
|
|
|
|
|
OH, it's probably b/c I am in win98, I will try on my Win2k.
Thanks
|
|
|
|
|
Oh, I can imagine it, nothing is really hack proof , esp this version
Thanks for the free software 
hehe

I have never done this. How do you load an exe as a resource? I hope I dont end up screwing half the programs on my machine.
|
|
|
|
|
well, in VC++6.0, FILE>OPEN
change the file types to .exe
change "Open as" to resources
then browse to the .exe you wish to "browse"

Interesting news report on C++ standards conformance. The highlight being that our very own Chris Maunder is quoted as the second authoritative source on the subject, right alongside Nick Hodapp.

Does anyone know how to deselect all the text in an edit control...I am using a read-only edit control which displays a resource text file. The problem is, is that when I open the dialog all the text is highlighted. I tried sending the message SendMessage(hwndEdit, EM_SETSEL, -1, -1); but still no luck. I also would like to hide the caret but I don't know how to do that either...Does anyone have any thoughts on this?

You probably need to have called SetFocus() to the control before setsel. When a edit control recives the focus, by default it selects the whole content. If you call setsel after setfocus this shouldn't be a problem.
Also take a look at the function CWnd::HideCaret() for the edit control, that may help you.
