I am not sure about the approach that u have specified here.
But the following approach will server the purpose of enabling / disabling the tool bar controls.
You need to add a function in your view class.
For example…
Add ON_UPDATE_COMMAND_UI(ID_FILE_NEW, OnUpdateFileNew ) at location shown.
CMyView.cpp
file
=======================================================
BEGIN_MESSAGE_MAP(CMyView, CScrollView)
//{{AFX_MSG_MAP(CMyView)
other message handler functions...
ON_UPDATE_COMMAND_UI(ID_FILE_NEW, OnUpdateFileNew )
other message handler functions...
END_MESSAGE_MAP()
Void
CMyView:: OnUpdateFileNew(CCmdUI* pCmdUI)
{
if( some_Condition)
pCmdUI->Enable(true);
else
pCmdUI->Enable(false);
}
CMyView.h file
Public:
void OnUpdateFileNew (CCmdUI* pCmdUI);
Framework will keep calling OnUpdateFileNew function frequently and will keep the tool bar option enabled or disabled in a way u want.

You're getting a failed assert because m_wndToolBar is just a C++ object, it's not a window so you can't use the methods that operate on the underlying toolbar window.

Is Microsoft still investing on the development of MFC or is giving it up and rather concentrating on the .Net ?
Will applications written on MFC have their future ?
|
|

What do you mean by "future"? I find it to be an extremely vague term here. I will not explain you it in great detail, but "MFC is something that should not be compared with .NET", for the obvious reason why and where these technologies are employed. If MFC had to die, it must have been buried by now. There are more exciting things, but MFC won't die. It may rather take a different form. May be. Read more on managed and unmanaged code.

You say "should not be compared with .Net" because one is compiled, and the other is interpreted, so MFC will not die because it serves the domain of the application that needs fast execution and total control on the memory, pointers,etc.
I am still having that idea, but I am seeing many things, look at DirectShow, we now have DirectShow .Net, thus performance and fast execution of code (a critical thing for video codecs,etc and most importantly the direct access to memory : the pointer is real and is not wrapped (image=pixels, and imagine what happens if in the middle of a DCT or FFT, the garbage collector decides to trim the image pixel matrix to ensure memory defragmentation!!!!!??????) in spite of that all i'm seeing those other things brahmma.
I agree future is vague, but of course I do'nt mean the simple execution of programs written in MFC: those written in MFC 1.0 of 1990 still execute in Windows Vista, let it general, look at companies developing user interface control, those offering mfc (bcgsoft,jockebox,prof-uis, etc) are bypassed by the tremendous companies fs offering kits for .Net.
The future of MFC wo'nt be affected by the companies that serves that ?

Why are you assuming things? I said it could not be compared, mainly because of where and how these technologies are employed.
I would again tell you, MFC is not going to die. Not anywhere in the near future, at least. It might take a different form, *may be*.

No no brahmma, I forgot to put the question mark at the end of the first sentence, I was posing a question, not assuming things, because that's the only thing I know as a difference(code execution) with the other fact that mfc developers gain a full and direct control of memory, unlike C#, VB.Net, where even an int is a complex placement in the RAM, and conversion can't be done on the basis of knowing the exact internal structures of your variable, and also data can move (GC) undeterministically (with regard to your own program execution flow)..
I heared some news that MFC is going to be sold such that Microsoft will no longer improve it.

Yes, it is, according to this report from the MVP summit by Joseph Newcomer.

It would seem that Microsoft have focused on .Net
I don’t think mfc will die anytime soon, I will still be using it for quite sometime.
I’ve worked with standard C to cs.net
I like mfc it allows me to create a quick GUI for testing c++ apps, which .net does but after I put it in a wrapper, sing a song, dance around the office etc.
mfc just isn't as easy as .net thats why .net is so popular its quick and easy (nearly) everything is just a system.iwant.myapp.todo.thisplease namespace away
However .net is great for the app that has been done before or the pretty buttons etc, i'd like to see more info from Microsoft on MFC... doesn’t bother me though.
Long live mfc!

Hi all,
I have a question :
how to use XML to support Visual C++ multi-language program ?
Please give me some documents/resources/suggests/webpages,if u can ;P.
very very very very very very very very thanks ,
neo

My question is, what has XML got to do with multi language support in Visual C++?
Do you have an extremely shivering hand that rolled the mouse over the smileys and clicked on them repeatedly or is that some kind of morse code?
|

Sorry if I've offended you. Enabling Unicode is simple. Just #define _UNICODE and UNICODE in your precompiled header file. Tell me what you are going to do with XML. Do you want to store your application related Unicode data in an XML file?
|
|
|
|
|
it doesn't matter.
i wanna save all of the strings to a xml file,
then i could modify other languages strings in that xml files,
and load strings from the xml file at program runtime.
because i think xml file support multi-language better than other functions.
but i don't know how to use this function.
thank u brahmma.

Which version of Visual C++ are you using? Check out Microsoft XML Core services. If you need to just store and retrieve a string, you could use a simple .inf file too. Using an .inf file may be easier, but XML has its own advantages and so it may be worth the overhead.

thanks.
i wanna learn to use VC and XML,and i will build a application of multi-language.
so,if you know any information about how to use xml to store the strings of a software and how to retrieve it by VC,tell me please!
thank you so much.

Read this[^] article. With that, you could process/build simple XML documents.

hi it very simple
let you support English, German and Hindi as in your multi language package
you define English = 1, German=2 and Hindi = 3.. then you can create XML like this
<XML>
<sentenceID ID=1>
<1> Some thing in English </1>
<2> Some thing in German </2>
<3> Some thing in Hindi </3>
<\sentenceID>
<sentenceID ID=2>
<1> Some thing in English </1>
<2> Some thing in German </2>
<3> Some thing in Hindi </3>
<\sentenceID>
</XML>
now you just have to find required ids from the sentence you required!

ThatsAlok: thank u very much!
But it's hard to me.
I'm a fresh.
I just konw I'll create a XML file like u said.And create some XML to store the App's resources of multi language's resources.
But I don't know how to use them in my program.
eg.1.how to define or change the default resource?
2.how to load resource form XML?
My mean is we should choose the menu: English/Greman/Hindi/...
Then the App was reshow the menu、title、frame and all of the characters in language of our choose.It look like .ini resource to support the multi language,but it's .XML resource.
In the program,I don't konw how to achieve it.
so if u konw,help me plz.
