.net - Gems Game Step Calculation In Other Word Some Math?

Feb 28, 2011

I have a program that scans an image and converts gems to specific numbers. Look at the picture below:So i have a table with numbers. Number 1 is for yellow gem, 2 for blue, etc...

Like:

A B C D E
1 | 1 2 3 4 5
2 | 3 5 2 4 1

[code]....

I want to calculate a step, to get 3 equal numbers (gems) horizontally or vertically. For example, in this table if i swap E2 with D2, D2 will be 1, and D2,D3,D4 creates a valid step, because it's all 1. I'm using VB.NET 2010.My table is 8x8 size, it's just an example above.At now i'm just have the values in multiple variables (A1=1, A2=3, so on..)

VS 2010 Hmwk - Display The Largest And Smallest Using Math.max - Math.min

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

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.

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).

1. The lens equation for a camera is 1/f=1/di+1/de , where f is the focal length of the lens, is the distance between the lens and the film, and is the distance between the lens and the object. For a certain camera, an object that is 18 cm from the lens is in focus when the lens is 9 cm from the film. What is the focal length of the lens?

.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?

Math - Calculate Rows Per Column For CSS?

Dec 11, 2009

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.

Math Question As It Relates To Pictureboxes

Mar 13, 2012

Im working with a Picturebox in VB using the following basic math equations. [code]I believe that this equation assumes I am working in a coordinate plane where the following is true (0,0) is the bottom left corner of the Positive quadrant

-x increases as you move right
-y increases as you move up

I am working in a coordinate plane where the following is true (0,0) is the Top left corner of the positive quadrant

-X increases as you move right
-Y increases as you move down

The issue is I am not sure how this will affect my original equation for intersection point.
