If you read my previous post about rects, I solved it and now enocountered another. They never end . Now when I have 84 RECTS in one array, I have to see in which RECT mouse is. RECTS are located like this in screen: 1.. 2.. 3 ..4 ..5 .. 6 7 20 33 46 59 72 8 21 34 47 60 73 9 22 35 48 61 74 10 23 36 49 62 75 11 24 37 50 63 76 12 25 38 51 64 77 13 26 39 52 65 78 14 27 40 53 66 79 15 28 41 54 67 80 16 29 42 55 68 81 17 30 43 56 69 82 18 31 44 57 70 83 19 32 45 58 71 84 that can look messy-those dots are there just to make space) Notice that the first line numbers are also the rect array numbers. It just was easier to do it that way. Now I have the location of the cursor, and it can be "rounded" to Left/Top value of RECT. But I don't know how to make a function which would quickly search if one of the rects matched cursor's position. That's what I'm asking.
