Hi I'm making a simple drawing program I used offset to set up a specific drawing.
The picture drawn with offset moves on the screen when i draw another picture everything drawn with this function moves by one pixel permanently on the screen. Cant find source of this problem.
It is an MFC aplication.

CS2::CS2(CPoint Start, CPoint End, COLORREF aColor)
{
	m_PunktP = Start;
	m_PunktD = End;
	m_Color = aColor;
	m_Pen = 1;
	m_EnclRect = CRect(Start, End);
	m_EnclRect.NormalizeRect();
}

CS2::~CS2(void)
{
}
void CS2::Draw(CDC* pDC)
{
	CPen aPen;
	POINT pt;
	if(!aPen.CreatePen(PS_SOLID, m_Pen, m_Color))
	{
		AfxMessageBox(_T("Pen creation failed"), MB_OK);
		AfxAbort();
	}
	CPen* pOldPen = pDC->SelectObject(&aPen);
	pDC->MoveTo(m_PunktP);
	pt.x = 0;
	pt.y = 63;
	m_PunktP.Offset(pt);
	pDC->LineTo(m_PunktP);
	[...]
	pt.x = 0;
	pt.y = -13;
	m_PunktP.Offset(pt);
	pDC->LineTo(m_PunktP);
	pt.x = -32;
	pt.y = 13;
	m_PunktP.Offset(pt);
	pDC->LineTo(m_PunktP);
	pDC->SelectObject(pOldPen);
}

Please post code snippets using the code block button.
Could you please elaborate a bit?
(I'm not sure I got you) You're trying to draw shapes at the mouse pointer position and are you in trouble because of too many drawings take place?

No it moves pemanently torwards lower right when I draw more pictures theyre just slipping off screen Unsure | :~

That's probably because your 'offsetting' m_PunktP on every Draw call (albeit you aren't actually using a 1-pixel offset).
What do you intend to do, instead?

I think the problem are those lines m_PunktP.Offset(pt);.
You are changing the value of this point with every call and because its a member variable this value is also changed with every call to Draw.

(I hope I understood your problem in the right way, not sure about this.)

Ok thanks a lot guys I got it I was drawing with coordinates it was enough to make a drawing close with -1 coordiante if starting position was (x,y) the total ending position had to be (x-1, y-1); else it moved by the difrence.
thank again cya

Hello everybody,

I have a class with one member function and member variable declared in the header file.
I have compiled my code and created obj file.
When I opened the obj file I saw the decorated member function in the obj file.
But I couldn't find the member variable in the obj file.
I want to know whether compiler keep the member declared in my class in obj file or not?

Please help me.

Well the class member is of course there. Anyway using dumpbin I may hardly find it (I assigned a fancy bit pattern to). In fact there is no symbolic name (or I failed to grab it).

If it's a member function then it will not need a decorated name, as it is merely defined by the compiler as an offset into the object. When an object is instantiated the code will refer to it by its memory address, and the variable will be located by the offset value.

Hi,

I need to parse a file which has spaces and tabs with some entries that i need to pull.
I'm using sscanf function.
How do I ensure that I skip the spaces and tabs which could be in randon number.
What could be a regular expression for this?

Well, skipping blanks and tabs is very simple. You may code you own implementation for.

I did not ask for simplicity or complexity but rather a solution.

The solution is in your hands (well in your brain). Write a function to skip balnks and tabs (you're supposed to be a software developer).

I guess you are not a software developer but rather a philoshpher who thinks about those sentences.
I need a urgent fix and dont want to travel googling. I guess the forum is to get answer and not to fight around and highjacking

Your guess is wrong: I'm actually a clown.

Do you really need google for that? Do you realize it is pretty basic stuff?

I suppose the forum should help, not give you code with a spoon.

Well, sometimes I really would like to be a manager, you know, just to kick in the ass the lazy developers...
