# coordinate

dear sir,

The below code is use to draw a random circle with random color in picture box have given size for high and width

The code should draw this random circle to be cover the area of the picture square in constraint :
1. be equal or less of the area of the picture.
2. not be cost more than maximum cost as in the image.

The inputs are:
1. high & width of the picture box by 2 combo box's.
2. the random size of fixed circle (high, width) will be selected randomly from the list box as in the image.
3. the cost of each circle size also selected for same index in the circle size list box as in the image.

The sub routine is worked fine to the constraints but:
1. Random some time is select one item and the we still have space to fill and also the cost still equal or same the maximum cost and we still have some cost to be add as well space and that is not correctly.
2. When it's start to draw new circle randomly it should not draw in coordinate of X if it's bigger than Y or if Y coordinate use much length that X the system will move to draw in consume more x to be close to Y coordinate and so except the if start will be 0,0 and or if the x=y length it's program choice to move any one.

the current code is move row by row when it finish fill Y then go to new x coordinate.--->

I quickly noticed this line:

Dim total_area As Double = (area_w) * (area_h)

What area is this calculating? is it the circles area?

This smells like homework to me....
abdallah1973

The total_area is the full space of picture box

the question is that we need draw number of circle inside this area but it must not be more than size of the picture box area and not more that maximum cost  =120000  as sample.

When it draw it must start from 0,0 and always measure for length of x and y.

That mean if it's start draw and the length  of drawing of x is more than y then the system will go to start consume more y length and so (balancing).

The system will random select size and cost from listbox  and also the colour of circle will be random.

The code is not for homework but it's a type of idea for doing some presentation for one client.
OK, I will see if I can recreate the solution. I fear you may be making this more complicated than it needs to be, so I will split it up into different sections.

One question though, what is the "cost"? what does that refer to?
