I don't know what that is.
Anyway, if you're program is ANSI how can you read Chinese Simplified? Isn't it supposed to need Unicode or at least MBCS or am I wrong?

Yes it will better to change the project setting with UNICODE support.
ANSI characters only 256 they wont support any East Asian language.

The OP says that Traditional Chinese works in his first post.

P.S. I make different LAN files using different language databases including "Traditional Chinese" and it works well, Only Simplified Chinese is creating problem.

I really don't get it how it can work with an ANSI program, but he seems to say that.

Yes it work smoothly in "Traditional Chinese"... Trust me, Other applications which reads are ANSI based... I am really confused why it's not working in the case of "Simplified Chinese".

Thanks.

My program is in UNICODE, and other applications(Which read from LAN) as i mentioned earlier were written long back and in ANSI... But when i make "Traditional Chinese" lan files the applications read the right data and i get right data in GUI.. I'm writing the unicoded data in the file(notepad) in my program...

So isn't there any way for "Simplified Chinese".

Thanks.

Also when i tried "Traditional Chinese" LAN files in "Simplified Chinese" operating system, It shows everything in English..I mean when i check LAN files it is in "Traditional Chinese" but when applications read from LAN files and display on GUI, it shows everything in English.. The OS is Windows7..

Also in Win XP, The application shows the mixture of right data and "?", It must mean that whatever application understand it shows it and for the rest it shows "?"..

Thanks.

CMFCRibbonEdit - how to capture event when user edits it and presses enter?

I have a CMFCRibbonComboBox (which is derived from CMFCRibbonEdit), and I've captured the event of the user selecting an item by overriding OnSelectItem. However I don't know how to capture the event of the user typing inside the edit box and pressing enter. I looked at CMFCRibbonEdit::OnKey, but it is not called. Should I place a message-map entry instead? In spyxx the class of the edit box is isn't "EDIT", but "RichEdit20A".

Here's my code so far:

class MyCMFCRibbonComboBox : public CMFCRibbonComboBox
{
public:
	MyCMFCRibbonComboBox(UINT nID, BOOL bHasEditBox = TRUE, int nWidth = -1, LPCTSTR lpszLabel = NULL, int nImage = -1)
		: CMFCRibbonComboBox(nID, bHasEditBox, nWidth, lpszLabel, nImage)
	{

	}
	
	virtual void OnSelectItem(int nItem)
	{
		CMFCRibbonComboBox::OnSelectItem(nItem);

		// DO STUFF
	}

	// CAPTURE KEYBOARD EVENTS???
};

Just override the rich Edit EN_CHANGE message.
It will be notified.

I tried overriding it in CMainFrame message map like this

BEGIN_MESSAGE_MAP(CMainFrame, CFrameWndEx)
...
	ON_EN_CHANGE(ID_RIBBON_BTN_COMBO, OnRibbonBtnComboChange)
...
END_MESSAGE_MAP()

But my function didn't get called.

Did u checked with spy++, which message is coming on clicking the Rich edit
From which control does your control derived from Combo box?

Well, while typing inside the edit control mostly 0x400 notify message is sent (EN_UPDATE). But it's called even when I'm not typing anything.

Why do you want to save your bitmap into your xml file ? This looks like a very ugly solution to me... Waht are you trying to achieve by doing this ?

Yeah but the question is: why do you want to use XML as a database ? Why not a plain standard database then ?

Can CSocket be used in this way?

//XSocket is sub class of CSocket
XSocket*psk;
//connect etc.

assume:
psk->Send(...)
is guaranteed to send a message to other side.

If the socket is colosed immediately after Send(...) as

psk->Send(...);
psk->Close();

is the Send(...) function still guaranteed to send the message to other side?

I guess that if Send is a synchronous call, it is guaranteed to send the message when the function returns.

Yes, given that the 'other side' is connected and active, the operation is guaranteed. You might want to check the return value of XSocket::Send(), just in case...

This just copies it into the socket send buffer, there is no guarantee that all data will be sent completely. Returning from CSocket::Send()[^] does not indicate that the remote peer has received all data. What you do might work in the LAN (in some cases), but it won't work reliable over the internet. Also see what's the proper way to close a TCP socket[^].

Hope it helps!
