Hi,
Because dividing class function declaration from definition does make sense, if the interface is to be seen by other modules. If the interface is just for the imlementation namespace of a certain module, I would not even put it into a header.
Why? Because I don't want to recompile other modules, if the private interface changes. And because splitting declaration from definition means more administration of code and higher cost. It's overhead, if I don't want to export the functions it declares to others.
This I think is a common concern of software engineering, and does not have to do with loving either one programming language or the other. Look, C++ has been called a multiparadigmatic language by it's founder. It should make us free to implement whatever pattern makes sense to us.

Consider why Tox asked the question he did (and that English is not his native tongue). It was not to belittle you, but more to find out if you actually knew what you were doing and why, or were just doing it because a friend's cousin's boss said it was the way to go. You'd be surprised at the number of questions we see here that should not be asked. That doesn't mean that the poster did not have a legitimate concern; it just means that they did not understand the problem first.

I do agree. Tox's question was the most interesting answer to mine I found, and so I was much interested in discussing it. I'm very sorry, if my message sounded unfriendly. It wasn't meant to be at all.

From the doc:
To open a folder, use either of the following calls:
ShellExecute(handle, NULL, <fully_qualified_path_to_folder>, NULL, NULL, SW_SHOWNORMAL);</fully_qualified_path_to_folder> or
ShellExecute(handle, "open", <fully_qualified_path_to_folder>, NULL, NULL, SW_SHOWNORMAL);</fully_qualified_path_to_folder>
And the handle should be the handle of your own window. The handle can be NULL too, but know what you're doing.

Every window will have a handle associated with it. If it doesn't matter to you, then pass NULL instead of your window handle.
BTW, Please stop saying "plz hlp me" in each and every message that you post. There isn't any real need for that. People will help you out here, provided you give adequate information.

This is the handle to a parent window. It receives any message boxes that an application produces, such as error reporting.

Hi Friends,
I have CRichEditCtrl in my appln.
I want to chang the text selection color to Red(default is BLACK).
Any one have any idea? 
Thanks

I think CRichEditCtrl::SetSelectionCharFormat() is the closest
you're going to get.
I don't see any specific message to set the default selection colors.

I have an MDI application using the MFC feature pack which has several dockable views. A couple of these views really need their width keeping above a certain size or else they become a bit pointless because you can't see anything on them which could confuse the less mentally agile of users.
I've tried setting the m_sizeMin variable in the CDockablePane derived view class but that only works in certain circumstances. When you dock with tabs and certain other situations it seems to get overridden. Is there a blindingly obvious way to do this that I'm missing?

This is what i did till now..
CTime currentTime=CTime::GetCurrentTime();
int nDay = currentTime.GetDay();
int nMonth = currentTime.GetMonth();
int nYear = currentTime.GetYear();
int nHour = currentTime.GetHour();
int nMin = currentTime.GetMinute();
int nSec = currentTime.GetSecond();
currentTime -= 2592000; ///30*24*60*60 (Seconds)
nDay = currentTime.GetDay();
nMonth = currentTime.GetMonth();
nYear = currentTime.GetYear();
nHour = currentTime.GetHour();
nMin = currentTime.GetMinute();
nSec = currentTime.GetSecond();
But i dont want to calculate it like this. Can anybody suggest me soem other method?

Try this instead:
SYSTEMTIME varTime;
GetSystemTime(&varTime);
varTime.wMonth--;
After the third statement, the month would be decremented by one. Kinda obvious, but you asked for it.
Add: Oops! I haven't taken account of the year January. But I think that you must be able to do it yourself now.

What about if you are on 30th or 31st of march? Or any other 31st where the moth before only 30 has? Won't it crash? :P
EDIT: Question was already below, I should read all before posting

That was discussed two posts below here[^]. But that is an exercise that the OP must take care of.
