Hi all,
I want to display a special font using UNICODE, in my MFC application.
I have used '_UNICODE' in preprocessor.
This is my syntax

TCHAR **strUnicode;
//...
wcscpy(strUnicode[0],L"U+0985"); //Bengali unicode of a single charecter

After that, i want to display bengali character by print value of 'strUnicode'. But it display 'U+0985'.

Can any one told me how to construct 'strUnicode' and to display charecter.

Thanks to all

Try using something like that:

std::wstring str = L"Special letters: \u0985";
MessageBox(NULL,str.c_str(),L"Caption",MB_OK);

Is there any difference between \x20AC and \u20AC for example ?
Characters size or code page issues or other?
I've thought they display exactly the same and wcscmp confirmed that produced strings are identical.

The former is a character escape for a hex number - the later is not a valid C/C++ escape character[^].

[EDIT] But MS VC++ happily compiled it - apparently, a MS-specific extension [^]: "If a backslash precedes a character that does not appear in the table, the compiler handles the undefined character as the character itself. For example, \c is treated as an c."

What do you know? I just found out about Universal character names[^]. They are not escape sequences, but can be used to enter various international characters.

I wondered why I used \u but I've discovered that it's C# equivalent [^] of the C++ syntax i.e C# routine.

hello,

I have used ModifyStyle to modify the style of a window from readonly to noreadonly but it doesnt reflect in the window.

CRichEditCtrl m_Table;

m_Table->ModifyStyle(ES_READONLY,0,SWP_NOSIZE);

Wht must be the problem

Re: modifystyle not working

KarstenK26-Oct-09 4:32

some styles cant be modified at runtime. In that case you got to destroy the window and create another in its place. I sometimes use 2 windows for that case (only one visible)

Have you used Spy++ to very the styles before/after the call to ModifyStyle()? Have you tried using SetReadOnly(FALSE) method?

This wont work as you have not got the Dialog item for your edit control ..

If you have an MFC application in the pretranslateMessage() or OnInitdialog() or where ever you want to introduce new property to the control :
GetDlgItem(Your RichEditControl's ID for eg.IDC_RICHEDIT_CTRL)->ModifyStyleEx(ES_READONLY,0,SWP_NOSIZE);
Invalidate();

If this answer helps Mark it as GOOD answer.

Draw a FRAMERECT() on top of ONTIMER() image refresh!

Hey Guys,

I am in need of a method to keep my rectangle frame, drawn with OnMouseMove() and OnDraw() with coords specified from OnLButtonUp() and OnLButtonDown(), on the top of an image that is being updated with and OnTimer() function every some odd milliseconds. Here are a few code snippets:

Drawing the framerect:

void LiveFeed::OnMouseMove(UINT nFlags, CPoint point)
{
	if (GetCapture() == this)
	{
	m_ptEnd = point;
	Invalidate();
	}
	CRect r(m_ptStart, m_ptEnd);
	CPaintDC dc(this);
	dc.GetSafeHdc();
	dc.FrameRect(&r,0);
}
void LiveFeed::OnDraw(CDC* pDC)
{
	CRect r(m_ptStart, m_ptEnd);
pDC->FrameRect(&r,0);

}

Updating the image with OnTimer() The BlitX function just transfers an image to the specified window from a camera:

void LiveFeed::OnTimer(UINT nIDEvent) 
{
	XC_BlitX(cam->GetHandle(), m_hWnd, 0, 0, 640, 512, Window);
}

This setup causes my FrameRect to be drawn but then it gets covered by my image being updated. I need a way to draw on top of a refreshing image. I think I may need to use some sort of graphic control, but I am really unsure where to start to tackle this problem!

Any help would be appreciated and thanks in advance for taking the time to read my post!

You should put all of your drawing stuff inside the OnDraw message handler. OnMouseMove and OnTimer should only change the state of your class and then notify the area should be updated (so that OnDraw will be called).

That's contemplated in 'notify the area should be updated' Poke tongue | ;-P

It is a logical step, implementation details left as exercise.

Ah, i think I understand. If I move my image update function to OnDraw() it should keep everything on the same "Timer". If I try this, how do I get OnDraw() to be called? The timer?

CPallini26-Oct-09 4:54

When you need a re-paint to occur (and hence a call to OnDraw happen) you've to code the sequence

InvalidateRect(NULL);
UpdateWindow();

Please read the related documentation [^], [^].
