- Please quote your code properly - firstly, select the "Encode HTML tags when pasting" option below the text box and paste your code in, and secondly, please enclose it in <PRE> tags, to display it in a monospaced font.
- Try telling us at least some of the error messages
Also - that second #include "stdafx.h" looks wrong. If you're using precompiled headers, the second stdafx.h will cause the compiler and pre-processor to ignore all the #include statements that occur before the #include "stdafx.h"

there's a ";" that should not be there at the end of this line :
<< p[x].name << " and height is ";

for visual C++ 2003 onwards, variables defined inside for loopswill not be available outside. either you've to make int x declaration just before the for loop or for teh second for loop define as
for (int x = 0; x < MAX; x++)

Please remove the unnecessary semi column at the end of first statement.

I am trying to understand something about MFC and resource files. By resource files, I mean files that end with the extension .rc. As I understand it, resource files can be used to create Menus and add short cuts. Please consider the following resource file:
<br />
IDR_MAINFRAME MENU<br />
{<br />
POPUP "&Output Options" {<br />
MENUITEM "&Create one", IDM_CREATE1<br />
MENUITEM "create two", IDM_CREATE2<br />
MENUITEM "create one", IDM_CREATE3<br />
}<br />
<br />
}<br />
<br />
IDR_MAINFRAME ACCELERATORS PRELOAD MOVEABLE<br />
BEGIN<br />
"C", IDM_CREATE1, VIRTKEY, CONTROL<br />
END<br />
Observe that the string “Create one” is prefixed by an &. The way I read the documentation (I am looking at the book Programming Window by Charles Petzold) the & is suppose to result in the C in Create being underlined. The fact that it is underlined will be a clue to the user that a short cut exists for that menu item. However, the character C is not being underlined. I am wondering what I am missing.
Important note: The book I mentioned above talks about C and developing code using the Windows SDK. The code I am writing is in C++ and it uses MFC. I am thinking that MFC is turning off the underline character.
Thanks
Bob

On Windows 2000 and up, the default behavior of underlining is a configuration option. Normally, they won't show underlining until you press the "alt" key.

Bob,
Thanks for the response. Is there way to set it up so that they show up by default? If so, please tell me how.
Thanks
Bob

It's usually in the display properties applet (right click on desktop and choose "Properties".
In Windows 2000, select the "Effects" tab and the configuration option is there.
In Windows XP, select the "Appearance" tab and then press the "Effects..." button to bring up the effects dialog. The configuration option is there.

Try pressing ALT? IIRC, Windows doesn't display the underlines until you press ALT.
Anyway - here's part of the menu code of an MFC SDI project with a classic menubar (selected on the User Interface Features pane of the MFC application wizard). It displays underlines correctly.
IDR_MAINFRAME MENU
BEGIN
POPUP "&File"
BEGIN
MENUITEM "&New\tCtrl+N", ID_FILE_NEW
MENUITEM "&Open...\tCtrl+O", ID_FILE_OPEN
MENUITEM "&Save\tCtrl+S", ID_FILE_SAVE
MENUITEM "Save &As...", ID_FILE_SAVE_AS
MENUITEM SEPARATOR
MENUITEM "&Print...\tCtrl+P", ID_FILE_PRINT
MENUITEM "Print Pre&view", ID_FILE_PRINT_PREVIEW
MENUITEM "P&rint Setup...", ID_FILE_PRINT_SETUP
MENUITEM SEPARATOR
MENUITEM "Recent File", ID_FILE_MRU_FILE1,GRAYED
MENUITEM SEPARATOR
MENUITEM "E&xit", ID_APP_EXIT
END
However, with VS2008, there is a second option for menus, which is "Use a menu bar and toolbar". This uses the menubar that comes with the "MFC Feature Pack" (it's a CMFCMenuBar[^]). This menubar doesn't appear to display underlines on the menubar (but does on the menu popups).
I hope this information clears up your issue...

Staurt,
Thanks for the response. When I press the ALT key it works. However, when I run Microsoft Word,
I see that there are Menu items that are underlined without pressing ALT key. In Word they remain underlined even if I press the ALT key again. I would like the user to be able to see the underline without pressing the ALT key. Maybe I need to send the ALT key to the program. Please comment.
Thanks
Bob

Even though they may have Windows configured to do otherwise?

David,
Thanks for the response. I am not sure how to answer your question. I know that when I run MS Word it comes up underlined. On the same system, when I run my program it does not until the user
hits the ALT key. I would like my program to be like MS Word. What should I do?

In that case, you could always change the registy setting. See here for more.

David,
Thanks for the response. I looked at the URL you suggested. I am not up on all this registry stuff so I may have missed the boat. Are you telling me that should set the field NoChangeKeyboardNavigationIndicators in HKCU\Software\Microsoft\Windows\CurrentVersion\Policies\Myapp
where the name of my application is Myapp.
If I have this right, is my install script suppose to set this up? By the way, the application I am writing does not currently set any entries in the registry. However, I have a feeling it should.

Which was the wrong one. The registry value instead is:
HKCU\Control Panel\Desktop\UserPreferencesMask
Note the value of the 30th bit when you change the checked state of the "Hide underlined letters for keyboard..." checkbox.

David,
Thanks for the response. If I understand your solution changing the registry value you suggest
will change it for every application on the system. That is not acceptable for my application. Maybe
I will just live with the default.

I would tend to ignore Word (Office in general) - Office is notorious for a) not using the standard Windows components, and b) not following Windows user interface guidelines. And the trouble with bucking the standard is that you're never going to benefit from improvements made in later versions of the OS.

I got an assignmet 2 make a program finds fourier expansion the specifications are:
It is required to write a program in order to which takes a time expression as a string and perform all the necessary parsing on the expression and generate the fourier series expansion of this expression. THe program should be able to recieve the period of the wave under study even if it was a piecewise continuous expression.
Please any1 can help me with this?

most certainly
1) learn how to spell - don't use text speak either
2) learn how to use google - since this is an assignment likely you already have some resources, including your tutor, course-work
3) read the top question of this forum - the one that is titled "How to get an answer to your question"
when you've done that, post some code back here if you're still having trouble - we don't DO assignments for people - we help them with code - you havnt provided any yet.

So...what form is the time expression in? I'll presume it's something like x = sin(t)
The tricky bit is parsing the time expression. You will need an expression parser - you can find grammar for an expression parser in many of the grammars[^] on the ANTLR web-site[^]. Yes, I'd probably recommend you use ANTLR to generate the parser from a grammar - it even has its own IDE[^]! Might even suggest you use Java for the project, as ANTLR's Java support is more developed than its C/C++ support.
You then also need an automaton that can evaluate the expression you've parsed (probably with substitution of variable values). That will enable you to generate a time series. Generating the fourier series from that is trivial and left as an exercise for the reader 
Spirit[^], which is another option for the parser generation, includes a calculator example that has a simple expression parser and an automaton for evaluating expressions, so that's another option.

There's a toolbar button for creating a new text file. When you save the file, give it a .cpp extension.

Is it possible to add a new string resource at runtime? e.g. I would like to add "My Custom string" with the resource ID "IDR_CUSTOM_STRING" (with some unused value) to the string table.
We wish to allow our customers to customize the application. e.g. where it by default says 'Some Program' and 'Some file type (*.som)', they might use 'Bob's Program' and 'Bob's files (*.bob)'. That info in particular is all encoded into the IDR_MYPROGTYPE resource in the string table. The constructor for CMultiDocTemplate only uses this resource to set those strings as needed. I could define a new entry in the string table, and use that, but that works for only a single customization. To allow complete flexibility, I want want to generate a new string table entry based on some data file that is accessed before the DocTemplate is created (early in CMyWinApp).
As the resources themselves as part of the exe seems frought with problems, so I am happy to leave that alone. It just seems that at some point that data must be loaded and allocated somewhere, somehow. I just want to add a new one.
Or... if there is a safe way to do it, just modify the existing one.
Thanks,
-G
