Build Failing When Adding A String, No Visible Errors
Mar 14, 2011After adding a string to the program from the resources the build always fails, and removing the string and the code to load the string does not solve the problem, as the build still fails. We've been using multiple versions of the program since this started happening with the most updated one, and adding the string is what started the failure in building even though we added other elements (like an exit button) and other forms without it failing. With the one that started with the build failures we've tried it on all types of computers and it does not manage to build on any of them, even one's with a new installation of Visual Basic Express 2010.
The exact line added that apparently makes the build fail is:
PictureAndInfo.infoBox.Text = My.Resources.StegmeierBreweryString
And the string added to the Resources isn't anything unusal compared ot the rest we have but it is this is:
The Stegmaier Brewery business began in 1857 when Charles Stegmaier first set up a shop. Since then the Stegmaier business has grown greatly. The size of their operation has grown from the original shop to the large building pictured to the left (opened in 1863 and purchased from Stegmaier in 1978). The Stegmaier Brewery Company was purchased in 1974 by Lion, Inc. and Stegmaier Beer is still produced today by Lion, Inc. and remains a popular choice among consumers.

View 11 RepliesVS 2008 What To Name Boolean Data Member And Boolean Method
Nov 17, 2009From what I read it is a good convention to name a method that returns a boolean value with the prefix of "is" or "has". So in keeping with this convention I am trying to name a method in my program with this prefix but I am running Specifically I have a class called Day. It is a simple class with a few data members and one method that returns a boolean value of true or false. The name of the boolean variable is isSpecialDay. This class has a method called isSpecialDay which takes the date of the day, applies some criteria to the date and then sets the variable isSpecialDay to true or false. My problem is that the boolean variable is named isSpecialDay and so it the method. What should I do?
Public Class Day
Private TheDate as String
Private DayName as String

Form On Load Event Not Throwing Errors?
Oct 7, 2011I just noticed this, but I had a for loop where I incremented beyond the number of elements in an array. Normally this would thrown an exception.
This was in a form load event, and all that happened was the rest of the code in the event never executed. If I wasn't looking for what was supposed to happen next I never would have known there was a problem!
There was no try catch block there... but I would think it would still stop program execution with an error.
Can anyone explain this? Do I have some stupid skip error checked somewhere (if this exists, I'm going to be really annoyed)? In a button click event I put the exact same code and it threw the error... it seems to just be a problem with a form load event.
