How a loop from VB6 to replace on loop in VB .NET?

[Dr. Zharkov]

Hello. I converted the project from VB6 in VB .NET 2003, however in the
following loop there are errors of a upgrade
(in Help of VB .NET 2003 is not written, how to correct these errors):

For x = Xmin To Xmax
CurrentX = Points(x, Ymin).Trans(1)
CurrentY = Points(x, Ymin).Trans(2)
For y = Ymin + 1 To Ymax
Me.Line(Points(x, y).Trans(1), Points(x, y).Trans(2))
Next y
Next x

The big request: inform, please, how competently to write this loop in VB
..NET?

Beforehand many thanks for the answer, Dr. V.A. Zharkov. Moscow, Russia.

Hi,

Try something like this.

Dim g As Graphics = Me.CreateGraphics

For x = Xmin To Xmax

CurrentX = Points(x, Ymin).Trans(1)
CurrentY = Points(x, Ymin).Trans(2)
For y = Ymin + 1 To Ymax

g.DrawLine(Pens.Black, Points(x,y-1).Trans(1),
Points(x,y-1).Trans(2), _

Points(x,y).Trans(1),
Points(x,y).Trans(2))

Next y
Next x

Dr Zharkov,
I am not particulary familiar with VB6. However, things
are done a little differently with graphics from what I have seen so far.
You need to return a graphics object from the form to begin working with
drawing.

Dim g as Graphics = g = Me.CreateGraphics

Then you can us the methods in g to draw lines etc. Please look this up in
your help. If you dont have help installed then install it. If you do not
have the option to install help, I suggest that you but a non pirate version
of the software and install it.
