Pass An Integer Variable From The Sub To The Function

Dec 18, 2009

I don't think I fully understand passing values from a sub to a module. Here is what I'm trying to do (problem is at the '****):

[Code]...

I think I've seen something like this before - where the actual function returns a value. Is this possible? Or would I have to pass an integer variable from the sub to the function, and then return it back to the sub?

Increase Variable Each Pass Through A Function

Jul 8, 2009

I have a variable that I am trying to get to iterate up by one, i.e. X starts at 0 x+1 on first pass thererfore its at 1 then x+1 on second function call therefore x=2 and so on. I've tried the different loop and for commands but I cant get one to stay until the next function call, does it need to be a global variable? I'm sorry if this is in poor form or improperly formatted, definently trial by fire going into the object oriented world.

Take A Section Of The Xml File And Pass It As A Variable To Another Function?

Jun 5, 2012

I am using XML literals to parse files that contain data. I was wondering if there is a way to take a section of the xml file and pass it as a variable to another function...

<XML>
<DATA>
<STUFF>
<blahblah>sdfsdf</blahblah>

[code].....

I know with XML literals I can use ...<STUFF> and get the info out of that section, but how can I take an entire section of the xml, like MORESTUFF and set it as a variable to pass to another function that can parse that xml?

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 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.

Pass Integer Array To C++ Active Control?

Mar 12, 2009

I'm using VB.NET within Visual Studio 2008.I have a ActiveX control on my form that contains a method that takes an Array. In VB6 I just passed in the array and it was populated OK. When I do the same in VB.NET, I get a result but the value of each index appears to be a pointer.Here is the C++ method code...

void CMyCtrl::GetRowInfo(const VARIANT FAR& vArray, short sNumRows)
{
// Declaretemp array to put the row list into
short asRowList[24];

[code]....

Here is the VB code (same VB6 and VB.NET...

Dim maintRowList(0 To 23) As Integer
AxMyCtrl.GetRowInfo(maintRowList, 24)

In VB6, the value of maintRowList(0) is in the range 0 to Windows screen height(its a pixel value)In VB.NET the value of maintRowList(0) is a value that looks like a pointer to me (e.g 285671429).In VB.NET, the type of the 1st parameter is Object. In VB6 it is a Variant. I've tried AxMyCtrl.GetRowInfo(maintRowList(0), 24) and got the same result. I think I need to get a pointer to either the array or the first element of the array but I can't see a way to do that. how I can pass an array to this type of C++ ActiveX method?BTW - I cannot change the ActiveX code so the solution must be within VB.NET.

C# - Pass An Integer As A String Parameter To A Method Without Calling .ToString()?

Mar 12, 2010

In VB.NET, it is entirely possible to pass an integer as a string parameter to a method without calling .ToString() - it's even possible to call .ToString without the ()'s. The code will run without a problem, VB will interpret the integer as a string without having been told to. In C#, these would cause compilation errors - you are required to call .ToString() and to call it correctly in that situation before it will compile. Is there a way to make the VB compilation process check for the same things as the C# compilation process? Would it be best practice in a mixed team to force this check?

Program Function - Says, "The Type For Variable [variable] Will Not Be Inferred Because It Is Bound To A Field

May 18, 2012

Public Class Form1
Dim x, c, number(0 To 19) As Integer
Dim s As Integer

[CODE]...

The variables in the brackets [example] do not actually have brackets in them in the original code. These are where the issues are. For both variables, it says, "The type for variable [variable] will not be inferred because it is bound to a field in an enclosing scope. Either change the name of [variable], or use the fully qualified name (for example, 'Me.[variable]' or 'MyBase.[variable]')." Now, I'm not entirely sure if this is a stupid question or not, as I'm used to VB '98 because that's what we use in my programming class at High School. let me know why this won't work.

-Note: The intention of this program is to continually loop the generation of numbers for this list until I tell it to stop. Button1 ends the program, Button2 generates the list one time only, Button3 is supposed to loop the generation of the list, and Button4 is supposed to end the loop, but not the program.

Setting A Variable To Accept The Result Of A Function By Calling The Function With Many Parameters

Feb 17, 2011

I'm currently working with a client's VB.Net code, which was developed for them by a small development shop a few years ago and which they purchased and have been maintaining and uprgrading since. This client's primary developer is out on indefinite (likely permanent) medical leave and I'm now filling in until they bring in a full timer (as I'm a contractor here). My current task is to add some functionality to a the VB.Net code they purchased. I'm finding practices and techniques in the code that absolutely baffle me and can't make the code do what I want. I'm starting to wonder if it's me and was hoping to get some thoughts on the code I've encountered.

For example: Setting a variable to accept the result of a function by calling the function with many parameters, clearing the parameters in the function, setting them to some value, calling another function with those new values, then never using the values returned by the functions. I'll add a code snippet in the first comment since this is already getting long.
