The following example defines a rectangle and fills it.
C++
VOID Example_FillRectangle4(HDC hdc)
{
Graphics graphics(hdc);
// Create a SolidBrush object.
SolidBrush blackBrush(Color(255, 0, 0, 0));
// Define the rectangle.
REAL x = 0.5f;
REAL y = 0.5f;
REAL width = 100.8f;
REAL height = 100.8f;
// Fill the rectangle.
graphics.FillRectangle(&blackBrush, x, y, width, height);
}
SUB GDIP_FillRectangle (BYVAL hdc AS DWORD)
LOCAL hStatus AS LONG
LOCAL pGraphics AS DWORD
LOCAL pBrush AS DWORD
LOCAL x AS SINGLE
LOCAL y AS SINGLE
LOCAL nWidth AS SINGLE
LOCAL nHeight AS SINGLE
hStatus = GdipCreateFromHDC(hdc, pGraphics)
' // Create a SolidBrush
hStatus = GdipCreateSolidFill(GDIP_ARGB(255, 0, 0, 0), pBrush)
' // Define the rectangle.
x = 0.5!

' // Fill the rectangle.
hStatus = GdipFillRectangle(pGraphics, pBrush, x, y, nWidth, nHeight)
' // Cleanup
IF pBrush THEN GdipDeleteBrush(pBrush)
IF pGraphics THEN GdipDeleteGraphics(pGraphics)
END SUB
