The following example defines a pie and then fills it.
C++
VOID Example_DrawRectangle4(HDC hdc)
{
Graphics graphics(hdc);
// Create a Pen object.
Pen blackPen(Color::Black, 3);
// Define the rectangle.
REAL x = 0.0f;
REAL y = 0.0f;
REAL width = 200.0f;
REAL height = 200.0f;
// Draw the rectangle.
graphics.DrawRectangle(&blackPen, x, y, width, height);
}
SUB GDIP_DrawRectangle (BYVAL hdc AS DWORD)
LOCAL hStatus AS LONG
LOCAL pGraphics AS DWORD
LOCAL pPen AS DWORD
LOCAL x AS SINGLE
LOCAL y AS SINGLE
LOCAL nWidth AS SINGLE
LOCAL nHeight AS SINGLE
hStatus = GdipCreateFromHDC(hdc, pGraphics)
' // Create a Pen
hStatus = GdipCreatePen1(GDIP_ARGB(255,0, 0, 0), 3, %UnitPixel, pPen)
' // Define the rectangle.

' // Draw the pie
hStatus = GdipDrawRectangle(pGraphics, pPen, x, y, nWidth, nHeight)
' // Cleanup
IF pPen THEN GdipDeletePen(pPen)
IF pGraphics THEN GdipDeleteGraphics(pGraphics)
END SUB
