VB.Net Noob needs some direction

Trying to accomplish this equation 100-150= negative 50. Instead I am getting a positive 50.

My head hurts. :(

Count = 2

First time through result = 0, myarray(0) = 100. So 100 minus 0 =100. Result =100
Second time through result =100, myarray(1) = 150. So 150 minus 100 = 50.

--------------------------------------------------------------

For count As Integer = 0 To myarray.Length - 2

result = myarray(count) - result

Next

I think I understand what you're trying to accomplish...

Take a closer look at this structure against your logic in the "Second time through" section:
Code: 
arrayVariable(index) = value

This.
Editing previous posts also breaks the flow of the interactions between posters, such as rendering my post obscure to a new visitor to the thread.

You're getting closer. I bet if you work out the flow on a whiteboard for the 3 items in the array against the "result" variable, you'll see where things are slightly jumbled.
 
I only see 2 items in the array. 100 and 150.

If it makes a difference, once I get this working, count will be a value entered by the user.

How many items are being loaded into your array? How does that get evaluated/processed when you look at the bounds in your "For" clause?
 
I am loading two items (100,150) into the array at positions 0 and 1.

For count As Integer = 0 To 2 - 2?

Here is the full code I am working with if it matters.

count = InputBox("Enter the amount of numbers you want to add", , "Enter")

ReDim myarray(count)
'Dim x As Integer


For count As Integer = 0 To myarray.Length - 2
myarray(count) = InputBox("Please enter a value for position " & count, "myArray")



Next

Response.Write(myarray.Length & "<br />")
Response.Write(myarray(0) & "<br />")
Response.Write(myarray(1) & "<br />")


For count As Integer = 0 To myarray.Length - 2

result = myarray(count) - result


Next
Response.Write("The sum of the values is " & result)
End Sub
 
Because when you call ReDim myarray(count), and count=2, you're telling it to allocate 3 elements.
 
There was nothing in the first 2 posts. The problem in full starts at post 3.

Try this:

Code: 
count = InputBox("Enter the amount of numbers you want to add", , "Enter")

ReDim myarray(count-1)
'Dim x As Integer


For count As Integer = 0 To myarray.Length - 1
myarray(count) = InputBox("Please enter a value for position " & count, "myArray")



Next

Response.Write(myarray.Length & "<br />")
Response.Write(myarray(0) & "<br />")
Response.Write(myarray(1) & "<br />")


For count As Integer = myarray.Length - 1 To 0 To Step  -1
result = myarray(count) - result


Next
Response.Write("The sum of the values is " & result)
End Sub

Why'd you give away the answer when the OP was so close?
 
Honestly he wasn't all that close but I didn't see the first posts. For something this trivial I don't think I revealed anything other than showing how to count the array properly and stepping backwards through it.

Not trying to sound superior, I've probably been doing this a LOT longer than you. Been writing code in BASIC since I was 10 and I'm 42 now. Just an old geek!;)

The main point was for the OP to actually read the suggestions posted, and take one more step on his/her own down the direction being pointed.

And on that same note...
