Logical problem

[bubak]

I have a grid, it is for all the minutes in a day. (

when I'm setting just one exactly minute, i'm "walking" with an rectangle in it (dc->rectangle), but there in the grid are two types of lines and so, when I walk by the 2px line with mi 1px_bordered rectangle, it get's lost of course (

There are 2 possibillities in my point of view
1) draw the rect smaller 1px in eatch side
2) redraw the line again and again (or a part of it)

Isn't there some better solution - sth like transparent layers for painting, some solution using XOR function, or whatever. thanx for now.

I've used the solution, that, when I draw a rect near the bold lnie, I redraw back the part of it, that get's redrawn with the rect. I thought, that it'd be slow, but it's ok. When I'll have a little bit time, I'll redo it with XOR drawing, but now I don't know , how to do it in VC++. Anyway, the problem is solved, the day is saved ;-)
