For that kind of parsing, I recommend expat[^]

You know I am not sure, there is so many meanings that it boarders on the ridiculous.

1) Windows programming: memory, icons, bitmap, dialog boxes, I/0, and strings.
2) C++: memory, I/O.

Oh, 1 applies to Mac programming too.

A resource is anything that you must draw on to accomplish the goal, including dependency on outside resources such as the Web.

In a Visual C++ program, visual elements in your program (menus, dialog boxes, bitmaps, icons, and some strings) are defined in a source file with the extension .RC, which is referred to as a resource script. This file is compiled and 'linked' into your program. The term "resources" refers to these visual elements.

Ellipse, how to draw without been filled?

includeh103-Jun-06 3:10

3-Jun-06 3:10

the DC functions: Ellipse, Rectangle ... are filled by current brush.

I hope they are draw only without been filled.

any idea to do this?

You can use from Graphic like this

<br />
SolidBrush Brush(Color(255,0,120,120));<br />
Pen pen(&Brush, 4.0f);<br />
Graphics graphics(GetDC()->m_hDC) ;<br />
graphics.DrawEllipse(&pen,100,100,200,200);<br />

Can you be more specific
and you need to using namespace Gdiplus;

I seen the reference to ‘graphics’ and understand we are at a crossroads between systems of programming for windows. That being said ignore it and select a NULL brush before drawing the ellipse.

Hi John R. Shaw,
you said that create null brush before draw ellipse in CDC
but in graphics if you run this code you see a ellipse with one stroke Smile | :)

3-Jun-06 5:44

we target to win95/98 and use VC6.

NULL brush, I tried it before in this way:

CBrush*pb=0;
dc.SelectObject(pb);

but the select is ignored (previous brush is still working).

any comment about null brush?

That's not what he meant by null brush.

dc.SelectObject(GetStockObject(NULL_BRUSH));

Select a null brush into the DC before calling the draw function.

<br />
CPaintDC dc(this); // device context for painting<br />
dc.SelectObject((HBRUSH)GetStockObject(NULL_BRUSH));<br />
dc.Ellipse(100,100,200,200);<br />
