cmon guys ... im stuck and REALLY need help

[cheatera]

ok shutting down this - cant do it alone ... is there ANY other similar project? searched all forums and didnt found nothing ... post atleast link to similar project - 2d design

You are very impatient! Opening a thread, bumping it after 92 minutes then stamping your feet after 4 hours when it is usually reconned you should not bump sooner than 24 hours.

To do what you want requires drawing using XOR so that when the rectangle has to be redrawn you first redraw it exactly as it was last drawn which will make it disappear, then draw in the new position, and you don't erase the background and so don't erase previously drawn items.

I don't think GDI+ allows you to use XOR for drawing. This means that either you make your own function for drawing lines where you calculate pixel by pixel what to draw, which would be slow I expect, or you use GDI for the lines because GDI does allow XOR and other logical mixes.

I could be wrong of course but that's how I see it.

sry, maybe i rushed it a little ... but i got little mad when i saw 30-40 views, and abs no response :\ ok will try with XOR didnt think of it thx for the replay will post if i have success

[cheatera]

update: ok stuck again ... same problem ... cant i just embed mspaint window? like object? i just need the coords "drawed" by the mouse but i must see where to put the lines, i need somekind of "background" ... searched all forum again ... nothing ... cant find it with olveviewer. cmon obj/com masters, where are you?

I am not sure about others but speaking for myself, the number of responses could easily reflect those who have an interest in the topic, but have nothing valuable to add to the topic conversation.

You should use double buffer and WM_PAINT. Hope, this will help you
