Array of a class???

[kevinheeney]

I have set up a class called - linestuff -
It is used for calculating the midpoint,slope ect. of a line.
I am also using it to save the X1,y1,x2,y2 of that line.

What I hope to do is have a user draw a line and then have it set up a new object and then save the coordinates

This is working for one line but Arrays cannot be declared with new.

Public newline() As New LineStuff 'LineStuff Being the Class

And then everytime they draw a line to have it make newline.x1 = e.x1 or something like that and then have n=n+1 for each new line. There has to be a way to dynamically call objects. What am I doing wrong?

I no that this is scrambled, but I had trouble describing my problem.

You cant initialize the whole array as new, you have to do that for each member of the array, like this:

Public newline(0) As New LineStuff

In the example you initialize the first member of the array which is at zero.

It is still saying that arrays cannot be declared with 'New'. Though I tried Public newline(0) As New LineStuff

Actually, that wouldn't work either. You need to set them to new separately.

Dim newline(25) As LineStuff 'don't create instance here
Dim i As Integer

'note: For Each..Next will not work here
For i = 0 To newline.GetUpperBound(0)
  newline(i) = New LineStuff()
Next

SOrry, I typed in the wrong thing

Dim lines(somenumber) as LineStuff
lines(0) = new linestuff
