This function fills a given rectangle by using the specified brush. The FillRect function fills the complete rectangle, including the left and top borders, but does not fill the right and bottom borders.
hdc
Identifies the device context.
lprc
Points to a RECT structure that contains the logical coordinates of the rectangle to be filled.
hBrush
Identifies the brush used to fill the rectangle.
The return value is TRUE if the function was successful, or FALSE if an error occurred. Use the GetLastError function to obtain extended error information.
The brush must have been created previously by using either the CreateHatchBrush, CreatePatternBrush, or CreateSolidBrush function, or retrieved using the GetStockObject function.
When filling the specified rectangle, the FillRect function does not include the rectangle's right and bottom sides. GDI fills a rectangle up to, but does not include, the right column and bottom row, regardless of the current mapping mode.
FillRect compares the values of the top, bottom, left, and right members of the specified rectangle. If bottom is less than or equal to top, or if right is less than or equal to left, the rectangle is not drawn.
