Derive from CFormView instead and you'll be able to create a control to display the icon.

Hi,
I'm a C++ professional programmer with also some experience with Java. I would like to enter in the .NET world but I don't know what would be better for my future projects: Try with Managed C++ or to learn C#? I've downloaded VS2005 and I've read that there is a new specification for managed C++. So, it seems to me that maybe managed C++ basements aren't enough solid and it will be better to take C# way. But, I not sure if it's good idea to abandon my loved C++.
Please, share your opinions with me.
Thanks a lot,

If you alreday know C++, VC++ 2005 will be your best choice for writing .NET applications.

I prefer to learn a new language
inspite to stick to any one for life.
But its good if they are putting up
Managed C++ , it will be worth studying.
Have u got the seminar given in IIM by
Mr.Azim Premgi he says Change is a fundamental
thing in life and if u cannot adopt to change
then u are not going to advance . The faster
u detect a change the more ahead ur in the
race.

Slightly late answer, but after just looking at this, I suggest going with C#. Unlike, C++, it was written for .NET and doesn't seem like an afterthought. More importantly, the documentation for C++/CLI, as it's now called, is terrible and it's almost impossible to find sample code for anything but the most trivial examples.
Anyone who thinks he has a better idea of what's good for people than people do is a swine.

Hi,
Thanks for your responses. I've just returned from my Christmas holidays and I feel enough "New Year Positive" to learn a new language. So, I'm going to try C# as my entry point to .NET. I hope to be able to be writting my first test apps in a couple of weeks

I'm interested in what experiences people are having porting existing C++/MFC apps from Visual Studio 2003 to Visual Studio 2005.
I'm having all kinds of issues - worse than any previous update:
- problems with manifest files not being generated
- time_t now 8 bytes from 4
- all kinds of CString issues which I'm still trying to resolve
- etc...
- finally get the app to compile and run in debug mode only for it to crash immediately (before it's even visible) in release mode.
etc..
The IDE productivity enhancements in 2005 are great, and it's got to be the way to go for all kinds of reasons, but why does it have to be so darn hard? Why should I have to spend a week trolling through obscure and inadequately documented language etc. changes just to get back to where I was before?
What's everyone's experiences so far of this process?

could you be more explicit ?

CString issues: This used to work and now it crashes (where CStringRes is a utility
object which returns a string resource content as a CString)
theTable.Format(CStringRes(IDS_STATSHTML_STRING), m_AvePctErr, diagMAPE, m_StdError, diagStdErr, m_StdDev, diagStdDev, m_ymean, diagMean, m_CorrCoeff, diagCorrCoeff);
The crash text, which I'm still researching, is:
Debug Assertion Failed! Program: ... File: f:\rtm\vctools\crt_bld\self_x86\crt\src\output.c Line: 1123 Expression: (state != ST_INVALID) For information on how your program can cause an assertion failure, see the Visual C++ documentation on asserts. (Press Retry to debug the application)
The release mode crash I'm also still investigating - obviously these ones are a
little tricky without the debug crutch.
However, whilst specific help is always appreciated, what I was hoping to get from
the posting was other peoples' experiences with the port. I'll still have
the problems, but at least I will know I'm not on my own! And maybe for people
who have not yet taken the plunge they will be able to better assess the task to
come.

the problem is here that in Visual Studio 2003 following line of code was OK :
someString.Format("x = %d",x);
in VS2005 you need to write :
someString.Format(_T("x = %d"),x);

Does this happen with all projects ?

I really appreciate your suggestion to help on th specifics, but I was really hoping
to just get a flavour for other peoples' experiences with 2003 to 2005 ports. Is
it a struggle for most people, or just me? I've since resolved the CString issue.
For what it's worth, this code worked fine in VS2003:
CString txt;<br />
txt.Format("The MAPE<span style="color: red">%</span> was %0.2f%%",
fMapePct);
In VS2005 you need:
CString txt;<br />
txt.Format("The MAPE<span style="color: red">%%</span> was %0.2f%%",
fMapePct);
No worry, it only took me 2 hours to work out! The solution is invariably
childishly simple once it's found!
So, more generally, what are peoples' experiences of porting from 2003 to 2005?

The 2003 to 2005 jump is way easier than the 6 to 2005 direct jump! Now that, can be painful

Hi all,
IDE is VS.7:
I've created a Doc/View project, and the view inherts from CRichEditView.
now when i open a file (OnFileOpen) i know the code behind the scene eventually is
void CDocManager::OnFileOpen()
{
CString newName;
if (!DoPromptFileName(newName, AFX_IDS_OPENFILE,
OFN_HIDEREADONLY | OFN_FILEMUSTEXIST, TRUE, NULL))
return;
AfxGetApp()->OpenDocumentFile(newName);
}
where the OpenDocumentFile of the CWinApp loads the file.
but how do i make the rich edit to display the file content?
thanks in advanced.

Have you looked at the view's OnUpdate() method?

Actually no, i haven't taken a loot at OnUpdate?
can you be more specific please....
i've managed to solved my problem using the StreamIn method of the RichEditCtrl....
and then read the file using the edit callback (saw a code in MSDN)
but, if OnUpdate is better ,i would like to know
thanks again

But doesn't this defeat the whole reason for using the document/view pair? Normally the document holds the data (whether from a New or an Open), and the view "asks" the document for this data.

can you?

I suggest you read through the Scribble example on MSDN. It covers most, if not all, aspects of doc/view.
