On ignoring the error I get my calculator and it runs properl.What is this error????

I am attempting to get my program to run another program. I looked on the FAQ and it said that one of the best ways to do this was using the WinExec command. I am trying to use this like so:
WinExec ("C:\Program Files\Microsoft Office\OFFICE11\WINWORD.EXE", SW_SHOWNORMAL);
I believe this is the correct format, but my compiler says that WinExec is an undeclared indentifier. I'm assuming this means that I need the correct header file. If this is the case, where can I get this header file from?

Just a note: You'll need to escape the backslash. The '\' character in a string signifies a special character. You need to use:
WinExec("C:\\Program Files\\Microsoft Office\\OFFICE11\\WINWORD.EXE", SW_SHOWNORMAL);

hello....not sure why the #pragma disable isn't working....
the app has 14 warning of C4503, I've checked the source file that been complant about, here is the first 4 line of abscommbuffer.h
#if !defined( __ABS_COMMBUFFER_H__ )
#define __ABS_COMMBUFFER_H__
#pragma warning( disable : 4786 )
#pragma warning( disable : 4503 )
it's other's app, I am not sure what exactly is this line doing:
std::map< std::string, std::list< std::string > > mapLists;
and the warning message:

C++ exception handling was used but /EHsc was not selected.
When the /EHsc option has not been enabled, an object with automatic storage in the frame, between the function doing the throw and the function catching the throw, will not be destroyed. However, an object with automatic storage created in a try or catch block will be destroyed.
|
|
|
|

but after I enabled the /EHsc option in project setting, I still get 14 same warnings.......not sure why is that.
Thank you for your time

That's C4530, not C4503...

Hey all, Lately my VC++ has been playing around and I figured what the problem was and it was that most of the header files were missing. Does anyone know were i could get the header files???
Thanks for any help at all I really need them.
My VC++ Version Is: Visual C++ 2005 Express Edition Beta 2.

Consider downloading and installing the Platform SDK from Microsoft.
All the Windows headers are part of the Platform SDK.

This may seem like a silly question, but let's say we've got a pointer to a character array labeled str.
What is the difference between calling:
free(*str);
free(str);
Wouldn't free(*str) just free whatever single character the pointer is currently pointing to? This seems pointless? But it's called like this all over the place in this piece of code I've just been given to fix so I'm trying to figure out why they put it in.
The problem is that the call to free(*str) is sometimes crashing the code, even when it's checked like so:
if (*str)
free(*str);
Thanks!

>>Wouldn't free(*str) just free whatever single
No. This type of logic is usually used for multi dimensional arrays.
str should be a pointer to a pointer, and derferencing it makes you point to the first element of a two dimensional array.
So str points to the pointer of pointer array, and (*str) points to the array of objects.
Check the following code:
http://code.axter.com/allocate2darray.h
http://code.axter.com/allocate2darray.c
Make sure that your code is setting the pointer to NULL after calling free. You may be free data that has already been freed.

If I need to retrieve a URL, preferable asynchronously, which is a better API to use:
URLDownloadToFile
or
WinInet InternetXXX functions?
I am writing a high level wrapper around this stuff and I'm not sure which is the best API to use.
From looking at some articles here on CP it seems there are various issues with WinInet, while URLDownloadToFile seems MUCH easier to use, and it's easy to handle authentication for password protected resources.
My only concern is that it seems that URLDownloadToFile depends on IE being present. Is this worth being concerned about?
Thoughts?

Pfft, I guess it helps to look closer 
It would appear that URLDownloadToFile is in urlmon.dll, not IE. Don't know why I thought that.

URLDownloadToFile has been introduced with Internet Explorer 3.0, so I don't think the problem is practical. If you want to be perfect, you may check for the IE version during installation and perform the update if needed - however I haven't seen a 9x system with IE 2.0 or lower for ages! I personally use much preferred Mozilla Firefox, but the IE libraries are always in the system anyway.

OK.
Other than the IE dependency, is there any reason NOT to use URLDownloadToFile? It just seems so easy to use, I can't fathom why anyone would fight with the WinInet functions?

Hi all,
There's some code I "inherited" a few years ago and never really had much of an opportunity to clean it up in a significant fashion until now. I've always left all the little nagging things in there because of time constraints.
One thing that's been bugging me for a long time is that for every registry I/O operation occuring in this code (hundreds, some in loops), the original developer first verified the OS the program was running on. If it's Win9x, the string built to open a registry key is formatted to start with HKLM\SOFTWARE. If it's something from the NT line, then the string is HKLM\Software.
Is this absolutely, positively pointless? Are there any circumstances under which, if I settle on one case (without doing the check) the registry I/O call will fail? I've NEVER come across anything that would indicate this could happen, but at the same time I've never come across anything that guaranteed it would always work either regardless of case. My own tests on everything from the original Windows 95 all the way to Vista 5219 show that this check is utterly useless, and I could skip it entirely.
I'm very tempted to do so (and thus get rid of hundreds of these calls, and streamline all the registry string building code in the program), but not before I can find some (Microsoft?) documentation reassuring me that case sensitivity in registry key names is irrelevant.
Anyone can give me a convincing argument to leave this seemingly useless code in there? I mean, surely this check was added in the first place for a reason...?

Hi there,
I found a way to put any control or form I want into the taskbar (not just the Icon).
I'm not covering elements in the taskbar, I modify the size of the tasklist in the taskbar to prepare it to add a control afterwards. This works fine but I need to know when something has been changed in the taskbar. This means I need to know if an icon is added into the taskbar, if the taskbar gets hided, if the position is changed, etc...
Does anybody know if there exists breadcast messages which are sent by the taskbar?
Thanks in advance!

Great f*cking googly moogly.
Somehow my dialog editor in VC7 broke; I no longer have access to the tools that add controls to a dialog!!!! The itms for adding controls are visible, but they are disabled at all times, even when a dialog is being edited.
I'm using VS.NET 2002.
Anyone know how to fix this pathetic state of affairs?

Fixed it. Restarting VS.NET did not help; rebooting the system did.
Whatever.

Hi all,
Iam looking for the C++ code for the following Question asap? if anybody can do it please reply back soon and also let me know how soon they can do and how much it costs. thank u..........
Introduction
Reverend Zeller developed a formula for computing the day of the week on which a given date fell or will fall. Suppose that we let a, b, c and d be integers defined as follows:
a = the number of the month of the year, with March = 1, April = 2, and so on, with
January and February being counted as month 11 and 12 of the preceding year
b = the day of the month
c = the year of the century
d = century
For example, July 31, 1929 gives a = 5, b = 31, c = 29, d = 19; January 3, 1988 gives a = 11, b = 3, c = 87, d = 19. Now calculate the following integer quantities:
w = the integer quotient (13a – 1)/5
x = the integer quotient c/4
y = the integer quotient d/4
z = w + x + y + b + c – 2d
r = z reduced modulo 7; that is, r is the remainder of z divided by 7; r = 0 represents
Sunday; r = 1 represents Monday, and so on.
Specific Instructions
Implement a MyDate class to represent a date. The input has to be read as a string using an overloaded input operator. Preferably, no accessor function should be used to set the values of the data members. While reading the specified date, your program should validate the format i.e. while July 31, 1929 would be correct, 7/31/29, July 31, 29, 31/7/29 for example would be incorrect. The MyDate object should be able to find its own day of the week! Write a test program that illustrates the use of your MyDate class. The input to test the program should include the following:
July 31, 1929
January 3, 1988
March 21, 05
December 12, 1960
9/31/2005
July 4, 1776
January 1, 1991
Include all the source code (well documented) and input files and sufficient representative output.
