RetVal% = BCX_PRESET(hWnd, X%, Y% [, DrawHDC])

 Parameters:

• hWnd Identifies the window where drawing takes place.
• Xpos% X-coordinate of the position.
• Ypos% Y-coordinate of the position.
• DrawHDC [OPTIONAL] HDC(Handle to Device Context) pointing to an already open HDC. This is useful if a device context is to be written to many times. In this case the programmer is responsible for closing the HDC at the appropriate time.

 Return Value:

• RetVal% is a nonzero integer if the function succeeds, zero if the function fails.
