Hi, first of all I do apologize if the question is already in the message board, but I cannot find it.
Here's my problem.
I've implemented a CDialogBar derived class (it makes common initializations to all the dialog bar I need); then I've derived from it a lot of classes each of which implements a specific dialog (created with the dialog designer); in one of them there are various controls (buttons, static text, list box, ecc.); when I add an event associated with a control (e.g. the OnClick event of a button) the designer creates the corresponding method in the class associated to the dialog. I run the program and the button is disabled.
If I move the entry ON_BN_CLICKED of the CDialogBar derived class' message map into the MainFrm's one, the button is enable, but when the event is fired and the method is called the 'this' pointer within the method points to the MainFrm instance (I would like that the reference is the CDialogBar derived class).
What's wrong?
Thanks in advance for any response.

Keep the event handler in the CDialogBar[-derived] class itself. To enable the button, you need to handle ON_UPDATE_COMMAND_UI like,
BEGIN_MESSAGE_MAP(CYourDialogBar, CDialogBar)
ON_BN_CLICKED(IDC_BUTTON1, OnButton1)
ON_UPDATE_COMMAND_UI(IDC_BUTTON1, OnUpdateButton1)
END_MESSAGE_MAP()
void CYourDialogBar::OnUpdateButton1(CCmdUI *pCmdUI)
{
pCmdUI->Enable(TRUE);
}

At this point you need to stop expecting more from App Wizard (done its job), you need to code now.

There's a nice toxcct's article about [^].
That article is actually undervoted (thanks to Mr. Univoter), but believe me, it is very good.

Well, (IMHO) while the advanced articles are quite enjoyable for the few of us able to understand them, the (well written) articles for beginners are the most valuable here.
Unfortunately, if you write a good article (as, for instance, another of yours: , your "The Beginner's Guide to Using Enum Flags" - Disclaimer: I'm not the toxcct's publisher  ) for beginners then you'll got a lot of attacks by the 'experts'.

Dont problem I can compile it for you. 
|

How did you create the dialogs?
And how did you try to set/get the values?
Are you sure that the dialogs are created at that time?

use PostMessage to send messages between the different windows. In the message you can update the windows. Think about a global data object which data is represented by all windows.

You can use of like this code for dialog box
CMain* m_Main=(CMenu*)GetParent();
m_Main->yourcontrols();

1. Use a video editting tool.(may be the one that created the current file)
2. There is AVI file management support in Windows SDK in the VFW category such as [AVISave^] and lot other AVI file functions. And there was a sample WriteAVI, when i searched for it i got [avigenerator^] from google.
BTW, for complex formats use DirectShow (instead of CAnimateCtrl) that can display any format that are installed on the target machine.

Hi All !!
I have developed an application say "MyApp" using visual studio 2005, in VC++.
When i build the application i get an icon with name "MyApp.exe" in the debug folder of the application.
so if i want to run in some other computer other than where i developed i just click this icon "MyApp.exe" for the execution of my application.
Now there can be two types of Computers where i can execute my application
1. A Computer system where Visual Studio 2005 is installed :: Here i donot have any problem to run my application
2. A Computer System where visual studio is not installed ::
So what are the minimum requirements of such systems (where there is no visual studio installed) in which my application can run successfully without any failure (i want to run my application just by clicking "MyApp.exe" icon ?

This minimum depends to minimum of your program and what dlls are used with your program

You must install the Visual C++ 2005 Redistributable package[^] on the target computers.
You can legally include this with your program installation.

And distribute the release version of the program

No, there is no need to install VS 2005 on target machine.
Just build your solution in Release mode and you can find a Release folder which will contain exe for same (of course you will see it's icon).
Mostly if it MFC application then there is no any problem to run on platforms above windows 2000/NT/XP and above.
If some dependencies are there then you will required to install extra runtime for that for example DirectX 9.0c. In this case developer should have DirectX 9.0 SDK and the user's machine should have DirectX 9.0c runtime installed on it.
You can see such example when you install any 3D game which requires DirectX 9.0, then this the dependency for that application.

No, but you need to install the redistributable package (see Rajesh's post). The only way to avoid this is to build everything statically (so link statically to the C run-time and MFC libraries).

I did it as below, any more efficient way?
std::wstring s(L"abc");
CString t(s.c_str());
VARIANT var;
var.vt=VT_BSTR
var.bstrVal=t.AllocSysString();
