Drawing a triangle with hatch marks?

So far my draw function draws my 'enclosed sections' circles and rectangles correctly with hatch marks (SolidBrush.lbStyle = BS_HATCHED;).

Now I would like to draw triangles with hatch marks also. I've drawn the tringle with the LineTo function. Since this isn't a predesigned 'enclosed section' but just 3 lines how do I hatch the enclosed area.

Is there a different function I should be using to draw the triangle instead of LineTo? Last night I tried something like PolyLine but I botched it up so bad that I deleted it.

Any pointers will be greatly appreciated.

I have attached my programs output to hopefully help clarify what I am up to!

Uh, lost my attachment somewhere.

I tried my Polyline hypothesis, no such luck it also just draws the outline with the pen (no brush hatch marks). I thought that maybe it would be treated as a "solid" and paint its interior!

Code:

---

        POINT ptA[4] = {
                0,0,
                1441,1441,
                2882,0,
                0,0};
        Polyline(hdc, ptA, 4);

I am sure there is an easy answer to my delima but I am too tired to figure it out. It's 1:40 in the morning and I am starting to zone out!
:(

Looks like maybe regions are what I need!

I figured it out, you can actually find stuff on MS site once in a while! Here is what I did:

Code:

---

        case 3:       
//        Polyline(hdc, ptA, 4);
//        SetPolyFillMode(hdc, WINDING);
        HRGN hRgn;
        hRgn = CreatePolygonRgn(ptA, 4, WINDING);
        FillRgn (hdc, hRgn, hHatchBrush);

        DeleteObject(SelectObject(hdc, hPerimeterBrush));
        FrameRgn (hdc, hRgn, hPerimeterBrush,1,1);
        DeleteObject (hRgn);

        break;

---

Or use a path:

Code:

---

BeginPath(hdc);
// Draw a triangle
EndPath(hdc);
StrokeAndFillPath(hdc);
