My target buffers are persistent must must not be allocated every time when
converting from String to char*;

Somebody can explain me why if I put a color with SetPixel the color showed
is of another value? For example: I've to draw a grayscale image. The color
RGB(90,90,90) become RGB(40,45,60). In the Visual C++ 6 help I see:
