The SHAPEDLGPARAMS structure provides information used to initialize the dialog box created by the L_DlgGetShape function. After the user closes the dialog box, this structure is updated with information about the user's selections.

Member	Description
uStructSize	Size of this structure, in bytes. Use the sizeof operator to calculate this value.
pBitmap	Pointer to the bitmap handle that references the 1-bit bitmap used for preview or processing.
pBackgroundBitmap	Pointer to the bitmap to be used for the background of the shape. This bitmap will be updated if the user chooses a new image using the Browse Image button. If you pass NULL, the "Tiled Image" and "Translucent Tiled Image" options will not appear in the BackStyle combo-box. The caller is responsible for freeing this bitmap when it is no longer needed.
uShape	The shape to use.
crBack	The background color. You can specify a COLORREF value, such as the return value of the Windows RGB macro, or you can use the PALETTEINDEX macro to specify a palette color.
uBackStyle	The background style.
crFill	The foreground color. You can specify a COLORREF value, such as the return value of the Windows RGB macro, or you can use the PALETTEINDEX macro to specify a palette color.
uFillStyle	The foreground style.
crBorder	The border color. You can specify a COLORREF value, such as the return value of the Windows RGB macro, or you can use the PALETTEINDEX macro to specify a palette color.
uBorderStyle	The border style.
uBorderWidth	The border width.
crInnerHilite	The inner band hilite color. You can specify a COLORREF value, such as the return value of the Windows RGB macro, or you can use the PALETTEINDEX macro to specify a palette color.
crInnerShadow	The inner band shadow color. You can specify a COLORREF value, such as the return value of the Windows RGB macro, or you can use the PALETTEINDEX macro to specify a palette color.
uInnerStyle	The inner band style.
uInnerWidth	The inner band width.
crOuterHilite	The outer band hilite color. You can specify a COLORREF value, such as the return value of the Windows RGB macro, or you can use the PALETTEINDEX macro to specify a palette color.
crOuterShadow	The outer band shadow color.
uOuterStyle	The outer band style.
uOuterWidth	The outer band width.
nShadowX	The horizontal position of the shadow.
nShadowY	The vertical position of the shadow.
crShadow	The shadow color. You can specify a COLORREF value, such as the return value of the Windows RGB macro, or you can use the PALETTEINDEX macro to specify a palette color.
uDlgFlags	User interface flags for this dialog, which determine the layout and action of the dialog. Possible values are:
	Value	Meaning
	DLG_SHAPE_SHOW_CONTEXTHELP	[0x00000001] dialog should contain a context sensitive help icon.
	DLG_SHAPE_AUTOPREVIEW	[0x00000002] auto preview when options change
	DLG_SHAPE_SHOW_PREVIEW	[0x00000004] show a preview of the image in the dialog. The pBitmap member of this structure should contain a valid bitmap.
	DLG_SHAPE_BACKSTYLE	[0x00000008] back style is an option
	DLG_SHAPE_FILLSTYLE	[0x00000010] fill style is an option

	DLG_SHAPE_BROWSEIMAGE	[0x00020000] browse image button is an option
	DLG_SHAPE_NO_TREEVIEW	[0x00040000] DO NOT use the TreeView
	DLG_SHAPE_CLASS_SQUARE	[0x00080000] squares are options
	DLG_SHAPE_CLASS_RECTANGLE	[0x00100000] rectangles are options

pfnHelpCallback	Pointer to an optional help callback function. If you do not wish to provide help to this dialog, use NULL as the value of this parameter. To provide help to this dialog, use the function pointer as the value of this parameter. The callback function must adhere to the prototype described in LTCOMMDLGHELPCB.
pHelpCallBackUserData	Void pointer that you can use to pass one or more additional parameters that the callback function needs. To use this feature, assign a value to a variable or create a structure that contains as many fields as you need. Then, in this parameter, pass the address of the variable or structure, casting it to L_VOID *. The callback function, which receives the address in its own pHelpCallBackUserData parameter, can cast it to a pointer of the appropriate data type to access your variable or structure. If the additional parameters are not needed, you can pass NULL in this parameter.
