Draws the specified three-dimensional shape into the target device context using the specified color, style, and size.

Parameter Description
hDC Handle to the target device context.
uShape Shape type. For valid values, refer to Effect Shapes.
pRect Pointer to the display destination rectangle.
crBack COLORREF value that specifies the background color.
hdcBack Handle to the source device context for background. Use this parameter and prcBack to place an image from another device context into the background of the shape. To use a background image, the uFillStyle parameter must not be EFX_FILLSTYLE_SOLID.
prcBack Pointer to the display background rectangle.
uBackStyle Background style. For valid values, refer to Effect Background Styles.
crFill COLORREF value that specifies the foreground color.
uFillStyle Foreground style. The following are valid values:
  Value Meaning
  EFX_FILLSTYLE_SOLID Solid filling ◼
  EFX_FILLSTYLE_TRANSPARENT Transparent filling ◻
  EFX_FILLSTYLE_FDIAGONAL Downward diagonal lines ▨
  EFX_FILLSTYLE_BDIAGONAL Upward diagonal lines ▧
  EFX_FILLSTYLE_DIAGCROSS Diagonal cross lines ▩
crBorder COLORREF value that specifies the border color.
uBorderStyle Border style. The following are valid values:
  Value Meaning
  EFX_BORDERSTYLE_DASH Dash line (valid only for 1-pixel lines)
  EFX_BORDERSTYLE_DOT Dot line (valid only for 1-pixel lines)
  EFX_BORDERSTYLE_DASHDOT Dash dot line (valid only for 1-pixel lines)
  EFX_BORDERSTYLE_DASHDOTDOT Dash dot dot line (valid only for 1-pixel lines)
uBorderWidth Border width.
crInnerHilite COLORREF value that specifies the inner band highlight color.
crInnerShadow COLORREF value that specifies the inner band shadow color.
uInnerStyle Inner band style. The following are valid values:
  Value Meaning
  EFX_INNERSTYLE_INSET Inner band inset
  EFX_INNERSTYLE_RAISED Inner band raised
  The inner band is available only for squares and rectangles.
uInnerWidth Inner band width.
crOuterHilite COLORREF value that specifies the outer band highlight color.
crOuterShadow COLORREF value that specifies the outer band shadow color.
uOuterStyle Outer band style. The following are valid values:
  Value Meaning
  EFX_OUTERSTYLE_INSET Outer band inset
  EFX_OUTERSTYLE_RAISED Outer band raised
uOuterWidth Outer band width.
nShadowX Horizontal position of the shadow.
nShadowY Vertical position of the shadow.
crShadow COLORREF value that specifies the shadow color.
hRgn Handle to a Windows region that defines the shape. This parameter is used only if the uShape parameter is EFX_SHAPE_REGION.
