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.

Write A Variable To A File That Has A Different Type Than The Function Assigned To The Variable

Sep 17, 2011

I have the following code that I am using to parse out a test file. I am getting variable conversion error in Sub Main() when I assign file = Read(). The return value of Read() is a TextFieldParser type. How do I assign the proper variable type to "file" so I can write the output to a text file?

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.

Multiple Variable From One Function?

Is it possible to get more than one variable from a function? In my attempt below currmiles is simply being displayed in both labels instead of _currmiles to Currmiles.Text and _currdays to Currdays.Text. I created a separate function for _currdays and that works but it seemed like too much code to get 2 variables

Detect Variable *name* (not Type) Within A Function?

Jun 12, 2009

So, let's say I have this code (VB.Net)[code]...

What I don't like is:

- relies upon reflection

- loosely typed (no compile time checking)

- I'd rather store the binding information somewhere other than ID, but don't know where else it could go within the aspx definition. Moving the binding declaration to the code behind would be better in some ways, but worse in others.

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.

VB 2008 - Return A Variable Using The Function

Jun 17, 2010

I am writing a program with multiple forms (for inputing loan/financial information - so they are set up exactly the same albeit a form number (ie: 1-6)) that feed into a summary page form to display each individuals form's information. When the user closed a financial form, it then feeds the information to a summary page using the code I have below: [Code]. I am new to working with functions, and have not been able to find anything that can show me how to fill multiple textboxes with them (I only know how to return a variable using the function to work a calculation). Any way that I can write a function (or any other call) for this would save me a tremendous amount of coding, and make debugging worlds easier.

How To Populate ListView With Variable Values

Jun 8, 2011

Let's say I have 50 cars and I created 6 attributes for each of the 50 cars (therefore 300 total variables and values for those 300 variables). These attributes are created and valued based upon the following structure:

Car1Name = "Dark Red Car"
Car1Color = "Dark Red"
Car1DoorCount = 4
Car1Cost = 10000
Car1Appeal = 10
Car1BoughtStatus = False

Car2Name = "Bright Red Car"
Car2Color = "Bright Red"
Car2DoorCount = 4
Car2Cost = 11000
Car2Appeal = 8
Car2BoughtStatus = True
and 48 others of similar structure/syntax

How do I take a a module with these variables and values and populate them into a listview within a form such as Form1 and ListView1 without continuously going into listview's UI and manually entering the data? The goal is to show the USER a list of 50 cars, their color, door count, cost, appeal, and purchase status.

Store Variable Values Between Forms?

Jul 12, 2010

My application sends information from Form1 to Form2 by means of a global variable on Form1 whose value is read by Form2.

This variable is basically used to tell Form2 what it has to do because it's value will change depending on different conditions.

All form2 is meant to do is load data from a database into DataSets which will "ported" to Form1 (the main form) for consumption. I use a Form for this rather than a class because there's a lot of data that will be loaded each time it's visible and I wanted[code]...
