CreateSolidBrush() doesn't make a "solid" brush

When I used CreateSolidBrush() to create a brush, and then used FillRect to fill an area with that brush, I was expecting that every pixel of the entire area would be the same color.   However, the brush doesn't appear to truly be solid.  I end up with what appears to be a dithered pattern.   Is this the way CreateSolidBrush works?   Or am I doing something wrong?   When I truly want to fill an area with a solid color, I am currently, creating a pen and drawing over the entire area with a loop of LineTo calls.

CreateSolidBrush() does not guarantee that it creates a really solid brush: it trues to do it, but the result might be dithered.
Checking if the result of GetNearestColor() and the COLORREF you pass to it are equal will reveal you whether or not a solid brush can be created.

Use GetNearestColor() as parameter for CreateSolidBrush() to be sure that it creates a solid brush.
