Do we have any SDK to get the charset for the current language OS?
I have an application which will dyanmically generate the html file and display. I have a requirement where if I am displaying the html in the Japanese OS, I should mention japanese charset in the content info of HTML file.
Thanks in advance.

My application is reading data from serial port. But the data may arrive at any random time. So i want to interrupt the application when data arrives on the serial port. Can anybody suggest me some solution to this problem.

You won't be able to use hardware interruptions in your program (and it's bad design also  ). A better solution is in general to spawn a thread that will poll the serial port for data. A good design for doing that is starting this thread in a separate class that will send a message to your application when data is available (custom message). This may sound 'complicated' but if you don't want to freeze your GUI, it is the best way of doing that.

From my experience in the past, polling eats processor resource even though we have added something in the loop in the thread like Sleep(1).
Personally I prefer to feed an event to the serial port API, and use WaitForMultipleObjects or WaitForSingleObject ...

Yes this is so true! Basically all those communication related applications have to be designed in multi-threading to prevent from GUI frozen.

Use Overlapped I/O and WaitForSingleObject

Is pTmpl initialized? In your example there isn't any init.
if yes what about pTmpl->UpdateAllViews(NULL); ?;)

How can i understand the child window which i got is of child dialog?
i did this to get the child.
CWnd* pWnd = GetWindow( GW_CHILD );
i want to know if pWnd is of child dialog?

I'm not sure that I understand your question, but I think that if you want to know what kind of object is pointing pWnd you could use
if(! pWnd ->IsKindOf(RUNTIME_CLASS(CChildClassName))){;)
//Error
}else{
...
}
|
|
|
|

Hope I understood your question
see IsChild[^]
and CWnd::IsChild

i got the child window using CWnd* pWnd = GetWindow( GW_CHILD );
but the pWnd i got is of the edit control of the parent dialog.
i need to get only the pWnd of child dialog and not of child controls.

Use pWnd=pWnd->GetNextWindow() in a while loop and exit when the pWnd points the right object.

Do you wish to check pWnd is a Child dialog or pWnd is a child of a dialog.
Use GetParent to find out the parent and then use GetClassName to find out the class.
You can also refer GetParentOwner.

What he need is to check whether a window ( got from hWnd ) is a dialog window or a child control ( means edit, static, etc. )

what about GetParent(..) api!

((CEchoServerDlg*)m_pDlg)->OnAccept()

This is simply a casting: the m_pDlg variable (stored probably as a CDlg* pointer) is casted to the type CEchoServerDlg so you can access functions defined in that class.
Then, with this casted pointer, you call the OnAccept function of the class.

Where can I find good info on casting I think I am always confused with it.

This is C style casting and you won't find a lot of information about that, simply because it is a simple principle: you just 'transform' a variable type into another. What don't you understand here ?
Anyway, if you want a good article on C++ casting, I suggest this one[^] but I think it's no really what you are looking for.

These casting operators are C++ standard 
|
|
|
|

This basically is "saying" the following:
"Regardless of the type of the variable m_pDlg points to treat it as if it was a CEchoServerDlg; call the OnAccept method through this pointer."
This will obviously cause problems if you cast an object into something its not.
For example:
CRect rc;
CRect *pNotAWindowAtAll = &rc;
DWORD dwStyle = ((CWnd*)pNotAWindowAtAll)->GetStyle();
This code will compile and run. At best it will crash at runtime and at worst it will not: it will not work correctly and it makes no sense whatsoever. A C-style cast like this just pretends that a CRect is a CWnd but the two classes are not related and it will end in tears. A cast like that is saying to the compiler, "just do what I say".
I often go on about this, but in my opinion (and that of most modern C++ programming books) the C-style cast has no place in modern C++ code. You should use something like this instead:
static_cast<CEchoServerDlg*>(m_pDlg)->OnAccept();
A static_cast will limit the type of cast. It will only cast between related classes, perform standard conversions and call user defined conversion operators. If used in my "bad code" example it will not compile - this is good: nonsense shouldn't compile.
