Thanks for responding led mike.

Is this true?
Or is there a way to accomplish maintaining the session data in a single location – perhaps the model and design you refer to.
At the beginning of my project, I spent a great deal of time “Applying UML and Patterns.” However, a serious illness permanently interrupted the collaboration I had with an expert programmer who encouraged me to develop expanded use cases, flow charts and a “conceptual model” of my program.
Recognizing that your message might be sarcastic, I reviewed these documents and realized that my program already contains series of functions that provide access to the user and internal data the program employs in its operation.
It appears that the interruption of the collaboration with the expert programmer may have occurred at a critical moment in that I had not yet, and still do not, fully understand what I have been doing as I worked to continue the development of my program without my expert collaborator. Perhaps if I had studied programming in college as my collaborator (and many others) did, my task might be easier.
However, the modeless dialog I mentioned is the interface to a flat file database I created and from which I hope to print information from numerous records I have synthesized into single record. Therefore, returning transient data present in the richedit control at a certain point in time remains useful (although the advantage of this was not evident during the design of the program).
If I understood how to solve my problem (or had correctly anticipated future needs in my model and design) there would no reason to turn to experts like you or a site like CodeProject for a bit of help, a friendly conversation or an educational response. Working in isolation can be a challenge in any discipline (physical biochemistry is a personal favorite), and it is good to have a place where you can ask questions and receive accurate, precise, concise and information rich responses. It is easy to laugh at those who seek to learn from you (and even misdirect them as a means of providing future entertainment), so a community like CodeProject in which shared enjoyment of programming, interpersonal respect and dedication to mutual aid trumps petty personal attacks is critically important.
Thank you again for your response, which suggests that one or more of the functions my program currently employs in numerous locations for the manipulation of data might be useful in achieving my goal. While this was already apparent, your response has spurred me to explore my design as a means of achieving my goal.
Thanks again.

Yes, and my reply was to Mark. Mark and I joke around some in the forums. At that time in the thread there was no indication that you would be interested in anything other than what Mark suggest, as many here on CodeProject are not.
I am happy to see that you are and that you have help. Things will go well for you given the track you are on. Don't worry about not having a formal education. With your attitude, the availability of information on the internet and your colleagues you will do fine.
It is very likely that your colleague helped you implement a Model-View-Controller[^] pattern. If so you will find that it satisfies all your requirements.

Thanks for responding Mark.
Please assist me by educating me when I am not saying things correctly. I am trying to learn through this process, and working alone and without [programming] training (or any level of programming talent  ) can make programming a challenge.
By “code running in a view class” I assume you are referring to the OnPreparePrinting virtual function I mentioned in my question (or perhaps one or more of the other virtual functions associated with printing from the view class such as OnPrepareDC).
Similarly, I assume your reference to “modal dialog” in your response refers to the modeless dialog I mentioned in my question.
You suggest that I might accomplish my by sending a message to the dialog (such as EM_FORMATRANGE), which is not directly accessible to the view because it is running in a different thread.
One of my problems is that I am not sure that I have correctly created my dialog and my access to it appears inconsistent. In one part of my program (immediately after dialog creation) statements such as
mDlg->OnDialogFunction();
appear to work fine, while in other parts of the program (such as OnPreparePrinting) this tactic fails.
This may be embarrassingly bad programming practice; however, it accomplishes my goal  which is important in the absence of continuous cognizant collaborators.
I will explore this clue.
Thank you for your assistance.

Well my reply didn't make sense. Your post clearly states "modeless" -
I don't know where I got "modal" from 
I'll try again...
Where are you trying to access the rich edit control from? Within the dialog class
or from another class?
You shouldn't need to find the window. You should be able to keep a CRichEditCtrl
member variable in the dialog class. From within the dialog class, you can use that
variable directly to manipulate the control. From outside the dialog class, you
can either make the control variable public and directly access it through the
dialog object, or better yet, add methods to the dialog class which internally use
the control member variable to access the control.

You'll need to make sure your mDlg variable is accessible from wherever you need it.
Where (what class) is mDlg located?

I would like to include in my program a dialog with a control to plot out an (x, y) position over time.
Every Class/ActiveX I have downloaded has give me compile or build faults. I then gave up.
Can someone suggest either a Class or ActiveX to download for VS 2005. I am planning to use it in a MFC application.
Many thanks,
Andy.

Hello,
how to delete/remove some character from a string, without using CString::Remove('\n')?
I have to remove all "newlines" (crlf) from a file!
Thanks for help!
regards

If the string for which you want to remove a character from is a CString object, why would you not want to use the Remove() method?

You need to:
(1) read the file.
(2) change the read content, removing CR LF occurrences.
(3) write again the content to the file.
You can use a brute force approach, i.e. reading a char at time and discarding unwantend ones (maybe you need to lookahead 1 char) and then rewriting all remaining characters. On the other hand, you can speed up the whole operation using buffers.
Hope that helps.

So your requirement is to modify the existing file? Or create a new one? Or.....
Your efforts to use this site to receive help will be more successful if you supply complete, accurate and unambiguous requirements.

Hi,
I am using VS2005 Professional edition (procured by my company) on Windows XP Pro SP2 to develop a MFC application. Currently I am facing two problems and I am unable to determine the reason for the same. The application is packaged using Install shield which also include VC++2005 redistributable binaries and installs it on the target machine if these are not located. On my machine I have two versions of VC++ 2005 runtime binaries (one for VC++2005 and other for VC++2005 SP1). Now on to the problem description
1. When I execute release version of my application on my machine and perform Print operation via Print Preview dialog box, the application crash. The stack trace shows a crash in the MFC library mfc80u.dll (8.0.50727.762). However when I execute my application on a fresh machine and performs the same application it works fine. My query is why is the application using MFC libraries from VC++2005 SP1. I have not installed VC++2005 SP1 on my machine and not sure which application installed them. I tried copying MFC and C Runtime libraries from VC++ 2005 redistributables package along with the required manifest files to the application binary folder but still the application is using MFC libraries from SP1 and crashes at the same location. If I perform print operation directly using Print Menu item, the application works properly under all conditions. So I doubt if there is a bug in my application or is the application crashing due to the fact it is not complied with VC++ 2005 SP1 but trying to use MFC libraries from SP1. Though I doubt that it is most probably the formal case but I am not sure.
How do I ensure that I compile my application using the MFC and C runtime libraries from the original version and not from SP1? How do I uninstall VC++ 2005 SP1 MFC and C runtime libraries?
2. The same application also has mail sending capability which works fine on all versions of Windows except on Windows 2003 Server Enterprise edition with SP1. On Win2k3 Enterprise edition the application hangs when using mail functionality and I have to kill it using Task Manager. I doubt if it is something to do with WinSock libraries on Win2K3 but again I am not sure if it is due to a bug in my application.
Kindly provide me some pointers which can help me in resolving these issues.
Thanks and Regards.

I have been facing that problem too. You should use the VC_redist.exe Setup for the VS2005 SP1 runtime.
You find it on the MS-websites.

Hi all,
I've just finished my c++ application on vc++ 2008 but I've found out that it needs the framework 3.5 to run. 
Is there something to configure to make it independent from framework?
Thanks.

so you didn't code C++ but C++/CLI...
if you're using pure Win32 or pure MFC, you shouldn't have any dependency to the .NET Framework.
but if you mixed both... don't wonder
|
|
|
|
|
In the project settings should be an option to specify the framework version.

Thank you for answering so fast!
But my project is pure prehistorical win32 api. It has no references to anything and I didn't find the framework version on the project settings either.
Maybe it's time to go back to good old vs2005

I have not used 2008. I have not read anything about it that would lead me to believe they dropped suppport for creating native C++ applications. It is far more likely that you just have not figured out how to do it.

Visual Studio 2008 needs the 3.5 framework to run. However, your (native) c++ applications compiled with VS 2008 don't need this framework.

Well, I finally solved it installing VS2005 , but I kept VS2008 too. If someone finds out the trick to make it work please write an article or something.

While trying to build this project I get the following link error:-
<code>Error 26 error LNK2019: unresolved external symbol "char * __stdcall _com_util::ConvertBSTRToString(wchar_t *)" (?ConvertBSTRToString@_com_util@@YGPADPA_W@Z) referenced in function "public: virtual long __stdcall SmartGraph::SetLegendText(wchar_t *,long,long,long,long)" (?SetLegendText@SmartGraph@@UAGJPA_WJJJJ@Z) SmartGraph.obj</code>
It seems to be caused by the line:-
<code>m_strLegend = _com_util::ConvertBSTRToString(strText);</code>
I am using VS 2005, any suggestions please.

You need to add the library comsupp.lib (see [^]) to your project Linker command line options.
