Using The Value From A Combo Box To Do Math?

Apr 13, 2012

I am trying to do math (-, +, *, etc) based on what a user selects from a combo box. The combo has the operators (-, +, *, /) in its items list. when the user selects one of them, I want to use that operator with the two numbers the user also provides from two text boxes.

dim intNumOne as integer
dim intNumTwo as integer
dim intAnswer as integer

[Code]....

'I don't think I want to concatenate here. but this is what I would like to happen (use the operator based on the users selection from the combo and the two numbers from the text boxes. I know I could write a select case or If statement but is there a way to do what I'm trying to do without Select Case or If? I tried to make theOperator a 'char' type variable but that didn't work either.

Mar 5, 2012

well i am having a couple of issues with this particular homework problem and this is my first programming class so there is probably quite a few mistakes well the homework problem is to take three double values entered by a user and display the largest and smallest using math.max and math.min and display the smallest and largest so i thought i could use a listbox and take the values that went to the listbox and assign variables to each so i can try to use each variable in the math.max and min but im not making it to far and i actually might be way off

Pick A Word In Combo Box A That Has Specific Words/phrases In Combo Box B Show?

Feb 24, 2009

i wanted to link options selected from Comb box A (general) to specific options in combo box B (specific). I want to pick a word in Combo box A that has specific words/phrases in Combo Box B show. But not all the words to show in the combo box B if they aren't associated with the Word picked in Combo Box A. Ex.When "Soda" is picked in A, only "Coke, Sprite, Fanta" should be visible in combo box b, not everything else.This is the code i used to make the boxes, but i don't know how to link them.

Private Sub MainForm_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
' fills the combo boxes with values
Me.xGeneralComboBox.Items.Add("Soda")
Me.xGeneralComboBox.Items.Add("Juice")

Doing Math Like Eval In Javascript?

Sep 20, 2009

Is there any way to parse a string in vb.net (like, built in methods), that can do math like Eval can? For example, 3+(7/3.5) as a string would return 2.

I am not asking for you to code this for me, I just want to know if there is a built in way to do this, if there is not I will code it myself.

I can wager that it would not be able to parse stuff like Sin(90) on its own, and I understand that would need to be replaced by Math.Sin(90).

.net - Allow Math To Occur On Instances Of Class?

Nov 27, 2010

Is there some interface I can implement to allow basic comparisons and math to happen as it would an integer?

For example, let's say I have the following class:

Public Class Something
Public SomeBigNumber as UInt64
End Class

I would like to do something like this:

Dim SomethingA, SomethingB, SomethingC as New Something
....
If (SomethingA-SomethingB) > SomethingC Then
'Do stuff
End If

I was hoping to be able to implement some interface (if that is even the right term for it) that would return the UInt64 contained in the class for comparison and math, if possible.

Looking For .NET Math Method That Will Zero A Negative Integer?

Mar 24, 2010

Similar in concept to Math.Abs() - I'm looking for a function that when given a positive integer will return the same integer. If given a negative, will return zero.

So:
f(3) = 3
f(0) = 0
f(-3) = 0

Yes, this is simple enough to write on my own but I'm wondering if the .NET Math class already has this built in or if the same can be achieved by cleverly chaining a few Math.* calls?

I am trying to figure out a calculation I can perform in C# to determine the rows per column. Let's say I know I am going to have 3 columns and my record count is 46. I know that I can mod the results to get a remainder, but I would like something more efficient than what I have tried. So I know I will have 16 rows per column with a remainder of 14 for the last column, but what is the best way to loop through the resutls and keep counts.

Math - Produce All The Possible Combinations Of Numbers

Oct 6, 2009

I have 36 numbers in sets of 5. (eg. 1-2-3-4-5, 2-3-4-5-6 etc..) I need to find all the possible combinations of these numbers which total the same sum. For instance the lowest sum would be: 1 + 2 + 3 + 4 + 5 = 15. The highest possible sum is: 32 + 33 + 34 + 35 + 36 = 170. Now every five number combination within these 36 numbers will sum up between 15 and 170. How would I go about this in vb.net to produce all the possible combinations which would total say 92.
