I have a *.chm file already. but how can I display it when menu item Help->Help Topics is clicked?

When I input text in a multiline edit box, if I type the text
to the edge, it automatically word wraps to the next line.
If I check HSCROLL, it does not word wrap, but it continues
on horizontally indefinitely. How can I make a multiline edit
box NOT word wrap without activating HSCROLL? That is, when
text gets to the edge of the box, it sticks until the
user hit carriage return forcing it to the next line.
Please, any response any one can give me will be greatly
appreciated.

What you want to do is to disable an edit control's word wrap. I am not sure you can directly do that. But you can use the EM_SETWORDBREAKPROC message to set your own word wrap handler and then do nothing in the handler. It might work, might not work! It's worth a try anyway!

In the resource editor, turn OFF Auto HScroll and make sure Want Return is turned ON.

Sorry, i misread the question; my previous response should have been:
In the resource editor, turn ON both Auto HScroll and Want Return.

Is there any way of removing word-wrap without clicking
Auto HScroll? If I click HScroll, then the user and
type text horizontally forever. I just want them to
go to the edge of the edge box.
Please, any response any one can give me will be greatly
appreciated.

Ouch, why do you want to do that?
I think you could probably implement it by handling the EN_CHANGING notification and just discarding keypresses after they'd reached the end of the line. To make it a bit easier, you'll need to use a fixed-width font and calculate the maximum allowed width ahead of time.

How about this, when the focus is away from that edit box, how can I
insert carriage returns at the end of the line? If I type in
long line really, long
line
and it automatically word-wrap, then I see two (2) lines, but using
these vc++ commands, I have only managed to count 1 line and that's
driving me nuts. If I could force \r\n to exist at the end of the
first line, then I would be happy.
Please, any response any one can give me will be greatly appreciated.

Alright, that's a bit easier. Here's what you can do:
- Retrieve the text
- Retrieve the inner width of the list box
- Get a screen DC (used only for measuring the text): (MFC)
CClientDC dc(NULL); - Get the font used in the edit box: (MFC)
pWndEdit->GetFont(); - Parse out the string one word at a time, measuring each word, and accumulating the lengths (don't forget to measure spaces & tabs). When you are unable to add another word without exceeding the width of the list box, insert "\r\n" and reset the accumulated length. Use (MFC)
CSize sizeWord = dc.GetTextExtent(strWord);
Have Fun!

I've been getting an odd crash within Microsoft's STL, something to do with locales... The scenario is a bit complicated so here goes...
I have a class in a static library that derives from ostream, like this:
<br />
class __declspec(dllexport) CMessageLog<br />
: public std::ostream<br />
{<br />
} ;<br />
Then, in a DLL that links in this lib, I have another class that derives from it:
<br />
class __declspec(dllexport) CSysLog<br />
: public CMessageLog<br />
{<br />
} ;<br />
Then, in my app (which uses the above DLL), doing this:
CSysLog log ;
log << x ;
causes a crash if x is anything other than a char*, std::string or char.
Stepping through in the debugger, the crash is caused by basic_ostream calling use_facet() which seems to be trying to get a facet, gets NULL and then tries to deference it.
Is there some special magic I need to do to get locales working from a DLL...?

Make all components of your app (main program, DLLs, libs) use the DLL version of the C run-time library. That should fix your problem.

 im still new in c++.im searching for a visual c++ code for stacks. infix to postfix. can anyone tell me how to get examples? i cant seem to find it!

I believe that you're looking for std::stack, found in the header <stack>.
stack is an adaption of deque.

I think you can do it with media player activex.

Look up direct show in the MSDN - it's part of DX and makes playing movie files a snap.

How I can set a variable that is global to all my application?
I mean, if my prog is one file, you declare it ouside any scope, ok.
In VisualC++ how I accomplish this?
I need a global variable, or a variable usable during the entire life of my program.
"Nelle cose del mondo non e' il sapere ma il volere che puo'."

Pick a single cpp file and declare your global variable in that file like so:
int g_iCount = 0;
Then in the header file that accompanies that cpp file make this declaration:
extern int g_iCount;
The extern tells the compiler that it will find that variable somewhere else in your program when it tries to link all of the modules together. So now all that you have to do is include the header file in any file that wants to use that global variable g_iCount.

Two things.
1. the best way to do this is to declare it in stdafx.cpp, and declare it extern in stdafx.h. Then everything can see it
2. doing so is very poor design. If you cannot make it a member of your CWinApp derived class ( assuming you use MFC ), then you should at least wrap it in a namespace so it is globally visible, but not 'global' as such.

One thing I avoid at all costs is app-level data definitions and/or declarations in stdafx.*. Making any changes means rebuilding the .pch file which often takes longer than the rest of the entire build process and defeats the purpose of having a pre-compiled header file. If I can't or don't want to make a global variable a member of the app class then I make a Globals.h file that gets included where necessary. Sometimes I make a class called CGlobals because it provides a convenient place to initialize and release the variables but this doesn't happen frequently.
