How To Pass A Function To A Function Is Functors/function Objects Avaiable In VB2010
Oct 12, 2011I 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 nr.com. 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
Apr 1, 2010I'm trying to undersatnd the syntax of calling a funciton and it seem confusing when I'm using a web service in ASP.net. Maybe this question should be in an ASP forum, but it is a VB question. This simple web service allows you to type in your name and it response with an alert box with you name.
My question is, How can you call a function with 2 arguments when the function is only defined for one. I understand that the second argument is actually a method that handling the respons, but how can you interchange function arguments for methods and how do you know that there are methods for
Here's my call:

Make Picturebox1(function Already Assigned) Perform The Same Function As Picturebox2(no Function Assigned)
Aug 1, 2009i wanted to ask how to make picturebox1 ,to which functions are already assigned, perform the same function as picturebox2 ,to which no functions are assigned.For example:I have already made picturebox1 and have assigned it alot of function like when play button is pressed then picturebox1.visible = true and when we press pause button picturebox1.visible = false. So now i decided to make a theme and have to remove the picturebox1 and want to allow the picturebox2 to havefunction of picturebox1.But when i disable the theme the function of picturebox1 should go back to picturebox1.

Dec 17, 2010Most conversion tools will still use VB6 syntax And so don't many people coming to .NET from VB6 - drives me nuts.Rewrite your program from scratch using all .NET syntax and not legacy VB6 syntax still supported in the .NET world.

Mar 15, 2012I am creating an RTF file programatically so that user input can be formatted and I can control the font.There's two problems:
1. vbNewLine doesn't seem to work. I've also tried vbCrLf and that doesn't work either. I just want to introduce another blank line and not sure why it's not working.
2. Is there a way to use tab print positions to format things so they're not all just aligned left, center or right? (like tab(20); something etc..)

Oct 4, 2011I created a program using VB 2008 to aid me on design work-related calculations that uses Access mdb file for displaying info. and calculations. But I experienced an alarming problem when I converted it to VB 2010 The program execution works in VB 2010 but it can't display the data from an mdb database file.
To simplify and simulate the problem, I created a simple identical program in VB 2008 and VB 2010 showing a window that displays a data extracted from an mdb database file. Both programs run as intended in each environment. When I open the VB 2008 created program under VB 2010, VB 2010 converts it and when I run the program, it doesn't display the data at all.

Mar 22, 2011i am trying to make a webbrowser in VB2010, but one major roadblock that has been in my way for a while, is the fact that i can't get my bookmarks bar to work
i have no code to show you and i am completely open to ideas as long as i use a toolstrip just make sure that the bookmarks work and they are Saved when the program is closed and opened again.
Notes:
instead of "WebBrowser1" use:
"
CType(TabControl1.SelectedTab.AttachedControl.Controls.Item(0), WebBrowser).PutWhateverHere()
"
(i am using a dotnetbar tabcontrol so i need the "AttachedControl")
the toolstrip i am using in this case is called "BookmarksBar" so please don't use "ToolStrip1"
