Hi. I've been trying to find online on how to draw lines in a canvas using Netbeans IDE.I'm currently making a desktop application that calculates for certain physics things. My main issue is that I can't figure out how to draw into a canvas.I've looked plenty on google, and what I run into is code that doesn't clarify my issue. All I want to know is how to draw some lines into a canvas that has been created with Netbeans by pressing a button. Any suggestions are more than welcome. Thanks for your time.

Nevermind I got it :-D

I have something but it's not quite right, because years ending with 00 before de decimal are not leap years (example 1700 1800 1900 or even 2000000 as long as it has 00) I don't know how to do that. Also thanks for your help Guffa. Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim y As Integer y = TextBox1.Text If y Mod 4 = 0 Then TextBox2.Text = "is leap" ElseIf y Mod 400 = 0 Then TextBox2.Text = "is leap" Else TextBox2.Text = "isn't leap" End If End Sub

that will work fine, I forgot to specify that I need to do that with my own codes, only using if, else if in the code and textbox for input and another textbox for output and a button. Thanks for your help though
