OK guys I am to the point now I would just like to see this program run the way it need to gonna post the code I have not asking anybody to write it for me but give me some information and just let me know how bad my code looks I'm sure that I have several bad practices and such going on any info you can give me will be great. there is just a couple of thing that isn't work at the moment and that is in division the numbers are not working out to be evenly divisible

Solution 1

You're looking at the problem backwards. If you want an evenly divisble problem, start with the answer and work backwards. In a problem of "X / Y = Z" Pick a random answer value (Z) and multiply it by your divisor (Y) to get X. The result is a very neatly divisible equation.

Dave thanks for the quick reply it sounds like a clean way to get what I am looking for but I'm very much a novice when it comes to coding in vb.net could you give me a piece of sample code to look at that would achieve that.

Dave Kreskowiak 2-Mar-12 12:55pm

Seriously?? This is very simple math...

Dim RNG As New Random() ' Need a random number generator...

Dim num1 As Integer
Dim num2 As Integer = RNG.Next(1, 10) ' Will return 1 to 9...
Dim answer As Integer = RNG.Next(1, 100) ' Will return 1 to 99...

' For example, num2 = 5 and answer = 60
num1 = num2 * answer

' Output:
' 300 / 5 = 60
Console.WriteLine(String.Format("{0} / {1} = {2}", num1, num2, answer))

Of course, you'll have to modify the ranges in the RNG.Next calls to limit your problems to whatever you want.

Thanks again Dave gonna try to put this together and make it work. Yea seriously lol I think I have just been looking at this stuff and over thinking it for way to long. i know its simple math and I appreciate you patience and time

Everbody starts somewhere! After 30+ years of writing code, even I overthink stuff sometimes. Good Luck!

Solution 3

0) I gotta tell you that using the Call keyword is completely unnecessary in VB.Net.

1) I don't see where you mod code is in the code you posted.

2) I don't see any loops in your code.

took the mod out when I added
Public Sub dproblem()
Dim dnum1 As Integer
Dim dnum2 As Integer = RandomClass1.Next(1, randnumtop)
Dim danswer As Integer = RandomClass1.Next(1, randnum)
dnum1 = dnum2 * answer
Gui.TopNumLabel.Text = dnum1
Gui.ConstantLabel.Text = dnum2
End Sub
as far as a loop goes didn't think one would be need it when I call the get problem on button i guess that is where I am messing up
