Thanks for the people who answered my questions before ^^.
But I still have another problem. In the CPacket class, I need to add a static CRITICAL_SECTION m_cs (protected) to guard the m_counter. However, which place is good for me to put InitializeCriticalSecion(&m_cs) and DeleteCriticalSesion(&m_cs)? Is there any class initialization functions in C++ ?
Thanks
Hiya, Everybody ^^

You can do this to know if you need to initialized the critical section
if ( !m_cs.DebugInfo )
InitializeCriticalSection(&m_cs);

Ack, no don't do this. Race conditions in a MT program.
Very bad idea.

I know what you're thinking punk, you're thinking did he spell check this document? Well, to tell you the truth I kinda forgot myself in all this excitement. But being this here's CodeProject, the most powerful forums in the world and would blow your head clean off, you've got to ask yourself one question, Do I feel lucky? Well do ya punk?

Unlike Java, there's no facility in C++ for static construction/destruction. One can make it up nevertheless as this example shows:
class myclass
{
public:
static CRITICAL_SECTION cs;
private:
friend my_class::static_initializer;
struct static_initializer
{
static_initializer();
~static_initializer();
};
static static_initializer si;
};
CRITICAL_SECTION my_class::cs;
my_class::static_initializer::static_initializer()
{
InitializeCriticalSection(my_class::cs);
}
my_class::static_initializer::~static_initializer()
{
DeleteCriticalSection(my_class::cs);
}
my_class::static_initializer my_class::si;

I tryied to pass information from edit box to a CString variable. When the debug code is generated it works but when I generate the release code the variable is empty!!
By the way there is VC++ 6 it works.
for example :
CEdit m_edit;
.............
.........
void Cdial2View::OnBnClickedButton1()
{
int nLineLenght = m_edit.LineLength();
CString m_Str;
m_edit.GetLine(0,m_Str.GetBuffer(nLineLenght));
::MessageBox(NULL,(LPCTSTR)m_Str,"VALUE",MB_OK);
}
In VC++. Net this code worked when I used Multi thread Debug runtime library and it won't worked when I used multi thread runtime library.

I have a group box with a caption on a dialog. In the dialog editor it looks fine, the text is on top of the border so there is no line through the text caption. At runtime it appears the border is on top of the text, as the text has the line from the border drawn through it. I created this group box using the dialog editor. I have other group boxes on other dialogs which display correctly at runtime. However, I cannot see any properties that I have set differently between the two dialogs.
Does anyone know how to display this dialog so the text does not have the line from the border through it?
Thanks in advance,
Bob

the only time i have seen this is when the caption is a separate static control that you have placed in the tab order after the group box (i think its after)
either change the tab order to the other way round or use the built in caption of the group box
situations to avoid #37:
"good morning ... how many sugars do you take in your coffee ... and what was your name again?"
coming soon: situations to avoid #38: "...and the dog was there too?"

That's the problem, I am using the built in caption of the group box. I'm seeing it display two different ways in two different dialogs.

Hi..
I write a static linked MFC application and i need some advice about reducing the .exe size
I used the compiler optimization option (minimum size) but the release build is still big.
is there any other options?
also is it posible to tell if there are some coding practices to reduce the size ?
can i delete some unnecessary wizard code?
|

If it's not completely necessary, link in the MFC libraries dynamically. That should reduce your executable size considerably.

Search this forum for the word 'liposuction' and you will find a couple of interesting leads.

What's that do? It removes any code required for backward 98 compatibility???

RTFM 
But seriously - the default behavior of the VC6 linker is to make the PE sections aligned on 4K boundaries, which makes the EXE load faster after being defragged by the Win 98 defragger (which has that gimmick of placing clusters where they'll be read in faster from disk). Adding that switch goes back to the pre-v6 behavior of 512-byte boundaries, which makes for a smaller EXE (less padding within the file to get to 4K boundaries), in exchange for alleged slower loading times which no one will notice with today's hardware.

thank u
i wish to know if it is possible to reduce the size if i make my own classes enstead of MFC
for example writing my own CFIle?

I need to Trap the above, so that the user has to enter a pasword to exit the program, I allready trap PreTranslateMessage but "ALT + F4" must be decoded befoer this is called
It should be easy.........

What about just using an accelerator?
|
|
|
|

Just intercept WM_CLOSE. I think that should work for ALT+F4, close button, close context menu, etc.

Be glad I'm not a user of that program: I'd vote for more torture than the MS Explorer team should have (because they didn't do their stuff conciously malicious that you apparently do).
Now Virus writers are going to force users to write a password to get OUT of their programs?!
Why can't you just SEGV like every nice MS program?!

It's not me just my customer that request this function, the end software is used for process control, and they do not want the employee quitting the program to play card game ect.......

OK. A serious answer here would then be: replace Explorer.exe with your program. Seriously!
If you _only_ want your program to run on that machine, replace the shell with whatever you like.
But wouldn't that be wasting money for your customers, using full Windows installations as just the back-end for your program?

I have it sorted now, I just trap the WM_CLOSE message, and direct the user to my exit screen, its manly intended to stop the user accidentally closing the program, as they are generally not PC aware, and it would mean a call to the site engineer at 4:00am to go to site to get the system working again because we all know its always the early morning shift (that are bored) that cause these sort of problems and as the system is very expensive 1/4 mill Its a Big Machine the cost of NT4.00 is small, we usually use the policy editor to restrict access.
Thanks for the help
