I'm trying to create a cycling circle, so i should create one like this

I make a test but I not understood why the number init from a bad point

my test

I need to do this because I could do some statistics in the Italian lotto and calculate the distance between two numbers for example
between 90 and 45 the distance is 45 as you can see in this figure

Dear Silvio,

Please post your code so we can test it

My test

I made a small class because I need to make until 11 circles ( one for each weel of Lottery)

the numbers must be out of the circle
the number 90 must be as a clock at 12 o'clock, so the number 45 at 18.00
and on circle must be draw a pixel near to number
I think the positions must be save on array because I can calc the distance beetween two numbers

to draw the distance I made

@ 100,10 BUTTON oBtnPos PROMPT "Test position" of oDlg SIZE 80,22 ;
ACTION oCicloMetric:Distance(90,45)

To draw the distance beetween two number I made the METHOD Distance(num1,num2) but noy run ok the line is not good
the number distance is draw good ( 45)

On Paint I add positions of numbers on an array ::aPos

How I can resolve ?

it run ok only the line I must link two numbers

sample 90 and 45 or can be others (generally the 5 numbers of the draw per wheel)

I save the positions when I write the numbers

For a sample the number 1 is on row 10 col 234 I think it are pixel ?

This is the last Source code it seems run ok also the distance method

on test ( picture) I tried the numbers 11,40,45,54,68

as you can see the points are not on circle but on numbers and it is wrong
also the nDistance is write on bad place the ndistance must be placed on the middle of the line
that is, the geometric figure must be inside the circle
maybe the numbers (01-90) need to be more attached to the circle line
the linked numbers (in my test 11,40,45,54,68) must be highlighted or draw a small circle above

and there is another problem if you put a windows or a dialog over the ciclometric dialog the lines go away

I add the small circles near to numbers

but they must be on the line of the circle, how to do?

the Polypolygon not run ok I modify it with

Code: Select all Expand view RUN: ::line( aPoints [1][1],aPoints [1][2],aPoints [2][1],aPoints [2][2], CLR_RED) ::line( aPoints [2][1],aPoints [2][2],aPoints [3][1],aPoints [3][2], CLR_RED) ::line( aPoints [3][1],aPoints [3][2],aPoints [4][1],aPoints [4][2], CLR_RED) ::line( aPoints [4][1],aPoints [4][2],aPoints [5][1],aPoints [5][2], CLR_RED) ::line( aPoints [5][1],aPoints [5][2],aPoints [1][1],aPoints [1][2], CLR_RED)

now the geometric shape looks better, but the coordinates are still wrong because they are outside the circle

How I can resolve for the right coordinates ?

there were some math error, other errors because on FiveWin sometime parameter are nCol,nRow other times nRow,nCol :roll:

ok thanks but the numbers are bad
the 90 must be on top
