Private Sub Button1_Click(B yVal sender As System.Object, ByVal e As System.EventArg s) Handles...

I am assuming that the user is entering the infomation in the form with this solution.
If thats not the case ignore this.
you might consider an ontextchanged event like this
Place on the box used for entry of data
[code=vbnet]
private Sub boxname_TextCha nged(ByVal sender As System.Object, ByVal e As System.EventArg s) Handles boxname.TextCha nged

very simular to what was posted.
then I discovered that I needed to import "system.diagnos tics" to do it the way posted which...Leave a comment:

I Believe tha is the best way using 2 boxes one to check all and 1 to uncheck all. you can still do the check on the other boxes to see if all are checked.
Happy coding

The way you have your code written is causing the problem you are going to have to handle each checkbox seperately. like so
[code=vbnet]
' this part of the code checks to see if all others are checked and checks
' unchecks box 1 as needed (Note leave out the current checkbox your working on)
Private Sub CheckBoxChecker (ByVal sender As Object, ByVal e As System.EventArg s) Handles CheckBox2.Check edChanged
If CheckBox3.Check ed...Leave a comment:

Fractions code completed Part 2
Here it is cleaned up a little more.
Here's what this code does. It will take 2 fractions and add, subtract, multiply, or divide them. The user enters the fractions to be calculated into two textboxes. These can be entered as a whole number and a proper fraction, whole number and an improper fraction, just a proper/inproper fraction, or just a whole number.

Fraction code completed Part 1
Hi All For those of you that helped me with the questions on this... Thank you! I believe I have solved all the bugs in the code and wanted to post the final product. This is a set of code to solve basic frational arithmatic. using only 3 textboxes. Allowing the user to enter any type of fraction and get a proper reduced fraction answer. Feel Free to use it if you like it. Had to do 2 posts sorry was too long I guess.
