Yes, there are official documents that talk about conformance issues. I don't know how in depth they might be.

i want a function to do the following .
open a text file ..
check for a string given as input parameter to the function whether it is available in the text file .
return the string after = sign in the text file .
for example the text file may contain data as below
proj1=customer
proj2=report
proj3=client
if i call the function passing proj2 as parameter then it should return report and if pro4 is sent as parameter it should return failed/not found.
thanx in advance

My solution (which is not the only nor effecient one) would be make a CStdioFile, open the file, use the ReadString to put a line in a var (strLine). Take out the first x amount of characters (x being the Len(parameter)). Compare that var with the parameter, if equal then use strLine.Right(len(strLine) - (len(parameter) + 1)) to return your 'report', 'client', etc.
if don't find any, when reach EOF, just display 'failed/not found'.

Sounds like you are looking for a setup file.
There are heaps of articles on CodeProject to do this. You could possibly try something like IOBind.
If you have to do it your way you could try (in no particular order)
1/ boost::spirit, which is a metatemplate parser
2/ lex or flex, which are parsers
3/ use something like Lua, which is a scripting language which lets you get / set variables from a script
4/ use an XML parser (assuming you really do want a setup file) - maybe tinyXML
5/ use raw STL, iostreams, strings and string::find()'s
6/ use STL with boost::regex
If you can keep you head when all about you
Are losing theirs and blaming it on you;
If you can dream - and not make dreams your master;
If you can think - and not make thoughts you aim;
Yours is the Earth and everything that's in it.

or you could do it a simple way unless i'm missing some huge thing...
- input the string from the text file
- check to see if the first character of the string is NULL
- check to see if any of the characters in the string are '='
- if the above is true, put every character after the = sign inside a new string
- do what you need to do with that new string

Hi,
In the message map you have to have something like this:
BEGIN_MESSAGE_MAP(...)
...
ON_MESSAGE(999,OnEndlabeledList)
...
END_MESSAGE_MAP()
And in your OnButton1 function you have to
SendMessage(999);
-----
We are what we repeatedly do. Excellence, then, is not an act, but a habit.

SendMessage(999)
 
At least try something like
#define MAGIC_MESSAGE WM_APP+99 (or some other number)
ON_MESSAGE(MAGIC_MESSAGE,OnEndlabeledList)
...
SendMessage(MAGIC_MESSAGE);
MSDN states:
Message numbers in the first range (0 through WM_USER – 1)
are defined by the system. Values in this range that are not explicitly
defined are reserved for future use by the system. WM_USER is defined to be 0x400, so that your value of 0x3E7 (deimal 999) would send some message you did never intend to send to your window.

2 ways to do this. Easy way: you can break out the relevant code from the OnEndlabeleditList handler into its own public function, and simply call that, e.g.;
void CMyDlg::OnButton1()
{
CallSomeFunction();
}
Or you can, as you were trying to do, use SendMessage. You will need the window handler of the listbox window, or a listbox class, and call SendMessage on it and send it the appropraite message. If you look at the list box (or is it a list control??) documentation in MSDN you can find the right message. It'll look like one of these:
HWND hListWindow = ::GetDlgItem(ITEM_ID_FROM_RC_FILE);
::SendMessage(hListWindow, message_id, wparam, lparam);
theListCtrl.SendMessage(message_id, wparam, lparam);

Hello, I have a problem with my MDI. When the CWinApp constructor
is called in my program several initializes are skipped. Inside
the appcore.cpp that houses the initialization code I have placed a
break point where the initialization begins. When I step through
after the 'ASSERT(AfxGetApp() == this);' line, the code jumps to
the section called '// other initialization'. The break point for the initialization code has a question mark (?) inside of it.
So when I go to close my file and the CWinApp destructor is called,
I get an error. When I make a release of it and put it on another
computer without Visual Studio, the program doesn't start. (But it
does starts on the two computers with Visual Studio 7 and 5)
What do I do to get this to work? Please help me, I need to turn
this project in my Aug 15. Thanks.
By the way, I tried it making a new mdi and the code is not skipped
on that one, but I have followed the initialization for that.

That statement makes very clear that you accidentially messed something up with your class.
We need now to find out what exactly.
What are you doing in the Apps constructor that should not better be done in InitInstance()?

unfortunately, that's wrong. The CWinApp constructor is called before the CWinApp::InitInstance(). CMyWinApp constructor is blank like the new mdi. I put it in there before I found that out. I nor MFC ever calls CWinApp(), but it does execute. Now I need to know why is part of the code in that method is being skipped.
Thanks for the effort.

That is the way it is meant to be.

Good! Only some member variable initialisations belong there.

It is called while instantiating the one global instance of your application.
Look for the line CYourApp NEAR theApp; in your apps header.
pdunn wrote:

Place a breakpoint on your line CYourApp NEAR theApp; line.
Place another breakpoint on the first line of your InitInstance().
'F11' should take you right to the beginning of your (empty, as you said) app constructor.
Hitting 'F5' brings you to the breakpoint at the beginning of the InitInstance().
Where does your error come up?
BTW - You did a clean rebuild of your application?

Thanks for the reply.
My code is not being skipped. It is the MFC, appcore.cpp. The (+) denotes where I placed a break point.
CWinApp::CWinApp(LPCTSTR lpszAppName)
{
(+) if (lpszAppName != NULL)
m_pszAppName = _tcsdup(lpszAppName);
else
m_pszAppName = NULL;
// initialize CWinThread state
AFX_MODULE_STATE* pModuleState =
_AFX_CMDTARGET_GETSTATE();
AFX_MODULE_THREAD_STATE* pThreadState =
pModuleState->m_thread;
ASSERT(AfxGetThread() == NULL);
pThreadState->m_pCurrentWinThread = this;
ASSERT(AfxGetThread() == this);
m_hThread = ::GetCurrentThread();
m_nThreadID = ::GetCurrentThreadId();
// initialize CWinApp state
ASSERT(afxCurrentWinApp == NULL);
// only one CWinApp object please
pModuleState->m_pCurrentWinApp = this;
ASSERT(AfxGetApp() == this);
// in non-running state until WinMain
(+) m_hInstance = NULL;
m_hLangResourceDLL = NULL;
m_pszHelpFilePath = NULL;
m_pszProfileName = NULL;
m_pszRegistryKey = NULL;
m_pszExeName = NULL;
m_pRecentFileList = NULL;
m_pDocManager = NULL;
m_atomApp = m_atomSystemTopic = NULL;
m_lpCmdLine = NULL;
m_pCmdInfo = NULL;
...}
The second breakpoint at 'm_hInstance = NULL;' never gets called because that is where the code skips causing 'm_pDocManager' not to get initialize. Thus when the program is closed, an error occurs because the program is trying to delete an uninitialized pointer.
The value inside of m_pDocManager is junk. Furthermore, the second breakpoint has a '?' (question mark) inside of it. I don't know what this means.
Thus the error does not come from the initInstance like I first thought but the constructor of CWinApp.

I have never had to step through that file.
The only thing I can think of is that the code file you are looking at is different from the one that the debug info used for stepping is made from.
Anything I can think of is wild guessing, sorry! 
Are you perchance mixing MFC versions? Compilers (like VC++6 and VC++7 or VC++2003)?
In the 'project settings/debug' the line 'Executable for debug sessions' points to the correct .EXE?
You do link a 'debug multithreaded' library?
You let the compiler generate a 'Browse info' and a 'Program Database'?

I would like to have a sourcecode to automatically discover the computers in my LAN/Domain and execute a a program remotely to all the computers it discovers. This code should be able to list all the computers it found and if we right click on any computer name, it have an option to remotely execute the program mentioned. Can anyone help? I am not a good programmer and seeking you guys help to accomplish my task.

Steve,
They may call this a worm but my intention is to discover the PCs in the network and do a software and hardware inventory. Many software out there is being excutable using logon scripts and it is time consuming. Microsoft has a tool to check the network for any softwares installed and I do not how the mechanism works. So does the SMS Server do...Network Discovery. So, If I can have a source codes how to do this then I can write the program that will retrieve the information needed. Rgds,

Thanks to everyone who helped with my CEdit problem yesterday. To recap a CEdit which isn't in a dialog sends messages like WM_KEYDOWN to its parent. This probably happens in a dialog as well, but you don't see it as the dialog msg handler sorts things out.
In the end I had two problems. Clicking on the edit control resulted in a WM_LBUTTONDOWN going to the parent window, which closed the edit control. This turned out to be a problem with WM_MOUSEACTIVATE being sent to the parent, which caused it to active and thus get the WM_LBUTTONDOWN. So preventing WM_MOUSEACTIVATE being sent to the parent window solved my mouse click problems.
Second, my parent window has a PreTranslateMessage() function which handles WM_KEYDOWN etc. The problem here was that I wasn't testing if the msg.hwnd was the same as my parent hwnd. Adding that test resolved my kbd problems.
So I now have a stand alone edit control, which can work outside of a dialog. If anyone needs anymore info let me know. Thanks again to you all for your efforts.

Great! Congratulation to get it running in that short time.
So, where do you use that control? I can only imagin a Edit control on
A) a dialog
B) a view or
C) modeless (but that would again be a dialog)
What are the other possibilities to place it?

I've written a custom tree control which doesn't use the MS TreeCtrl and I needed this to allow editing of tree items. The tree is on a dockable control bar in a new app I'm working on.
When I was trying to resolve this I found a post to a mailing list where the person was trying to use a CEdit in a CView and had exactly the same problem I had.
You'll see people using CEdit on Toolbars, Status bars etc. and they don't have the problem there, as these bars don't get focus!

This is not a specific C++ question, so if anyone suggest a more suitable board, I'm all ears.
Does anyone know of any good sorting utility? I have huge test files (20-30MB) that needs to be sorted on a regular basis. I have used a DOS program called MSORT, but this takes ages to finish,
and has no batch processing facility.
Any suggestions welcomed.
