.net - Address Varaible Names Where The Name Inherently Begins With A Number?
Nov 1, 2011Part of the challenge of writing maintainable code is a good naming convention. But sometimes a good, meaningful name involves a number being at the at the start of the variable. For example, take a 401k. Theres not another name in which to call it, and the litteral spelling of it is kind of taky (FourOhOneK).
[Code]...
I can most certainly make my own obscurities for names, but I will and whoever maintains my code more than likely get tripped up on it one day. My question is, are there any conventions within the programming community that addresses this, or is this left up to the individual programmer/policies of the company that dictate this.

View 3 RepliesButton_click Event To Select All Checkboxes?
Nov 6, 2011I'm using Visual Basic 2010 express, and I can't seem to be able to figure out how to make a button_click event select all of the checkboxes in a CheckedListBox. For example, I created a checkedlistbox with about 34 entries in it, all of which can be checked. So I decided, to make it easier, I would just make a Button with "Select All" on it, but I don't know what kind of button_click event would select all of the items withing my checkedlistbox.

Pass Data To Dialog - Manipulate And Pass Back?
Jan 15, 2010Just started VB programming this week and have found a wealth of information about what I'm trying to do. Problem is, some of it is more complete than others.Here's what I'm trying to do:In Form1 (my main form), I want to instantiate a class that contains a couple of properties (speed setpoint and position setpoint). When I click a button, I want to pass this data to Form2 and populate two textboxes on Form2 with the properties of this object. I want to manipulate the property values on Form2 and click an OK button which closes the dialog and returns the manipulated data, updating the property values of the object. Here's the algorithm I'm following:1) On Form1, instantiate the class2) On Form1's "Pass Data" button click event handler, instantiate a Form2 object and invoke the ShowDialog method, passing the object as a parameter.
3) On Form2, overload the ShowDialog method to accept the object as a parameter and modify the method so that it returns the manipulated class data.4) On Form2, in the ShowDialog method, populate the textboxes with the class data that was passed in.Here's where I get stuck. If I press the OK button on Form2 (DialogResult.OK), it returns me to Form1, but what hook do I have in Form1 to receive the manipulated class data that the ShowDialog method is returning?Here's an example of what I'm thinking about:
Code:
Public Class Form1
Dim clsController1 As New MotionController

I'm sure it's probably a very elementary question, but every explanation I've found seems to be incomplete.
VS 2005 To Pass Or Not To Pass?
Apr 16, 2009I am looking for some input. I am helping with a web application that is fairly large. We have some logic factored out into classes, not a true business logic layer (yet ). The classes are setup to pull values directly from the QueryString or Session variables and I'm not sure that that mehtod is proper or even a

How To Pass The Variable
Jul 8, 2009ok to start i know very little about VB6 but i am very good in true basic lol (stupid school teaching the wrong language -_-) anyway im just asking you to make the answer as clear as possible because i don't know very much. heres the problem . ok in the above example i have a button that (for my example) can be used to build a house (lol) i then have a variable in the button sub called money which will have 150 subtracted from it when the button is clicked my problem is it say variable not defined when using this button ... i have declared the variable in a module and in form load along with my other 50 or so variables. my question is how do i pass the variable into this sub and then send the new value back into form load so it can be sent into another sub for more calculations.
