How To Pass A Function To A Function Is Functors/function Objects Avaiable In VB2010

Oct 12, 2011

I want to make an numerical integration method with takes in an analytic function and integrate it over a specific interval. For the numerical integration procedure I want to use some procedures in The problem is that these are programmed in C++ and they uses functors to pass a function to the integration method. How can I do this in VB 2010?

I want to initialize the function (i.e. set a=1,b=0 for function y(x)=a*x+b) and then pass the function to the integration method. Then when the integration method call the function it only calls the function with one parameter (i.e. x since a,b is already set)

What is the best way to do this in VB2010?I want to make a general integration method where I can pass any single valued function and integration limits.

I have just started using VB, and from what I have found so far it seems like the tools you have is

- to us a delegate for the function
- to use a lambda expression for the function
- send a pointer/adressOf
- to create a function class/structure and submit this to the function

As for now I am most inclined to create a function-class. But I am not really sure how.F.ex. I make different classes for each "uniqe function" I want to integrate, but how can I pass them to the integration function when I need to specify the argument type in the integration-function-call?This seems like a basic problem which applies to many Math operations, so I think it would be very useful to clarify this.

Function Syntax - Call A Function With 2 Arguments When The Function Is Only Defined For One

VB Coding In Excel?

Jun 21, 2011

I think I have a simple program to create, but I just cannot find the syntax to complete it.Effectively, what I'm trying to do is search down a column where there are cells with numbers and cells that are blank. I want to search down the column and find where there are two or more cells that that have numbers, one after another. I want to add a row beneith the last number and then add up the total of that batch of numbers in that column were searching down. I know that I'll be using a loop to step down each cell in the column to check on the contents of the cell. Also I want the loop to go from the top of the colum to the last record since the list length will frequently change.

(VB9) Coding Size Of Boxes?

Dec 7, 2010

I'm trying to set the size of a box without setting it in the properties dialogue box. My reason for doing so: I have text boxes stacked on top of each other. I need to alter properties of them after I place them and don't want to scroll through the list of objects (there are a lot) in order to find that specific item. Instead, I want to place them at different places in the form and then tell them where to be located, and what size they should be UPON FORM LOAD. I can't seem to locate the proper syntax in the book I am using, but from logic I have reached the following beginning of the line of code:

Me.txtVidPro.Size = 561, 130
Me.txtVidPro.Location = 63, 258

the only part I'm getting an error on is the x and y coordinates. please help me by pointing me in the right direction.

Coding - Backgroundworker Repeats Itself ?

Jul 12, 2011

I'm down to the final coding on one of my projects, when i notice that the backgroundworker behaved strange. For each time i run the backgroundworker, it repeated it self one more time, and the new time, it repeated one more time.

So, if i run the worker a third time, it would repeat it self 3 times.

First run: Runs one time
Second run: runs twice
Third run: run 3 times
And so on.

So, i'll post all the code from that form.

Here goes.
