How do I check if httpwebrequest is doing what it needs to do?
Since theres no webbrowser involved your kind of left in the dark and cant actually see if what you programmed worked.
I'm sure it is negligible, but given that I want to assign true to a boolean field from within a method, does this choice make any difference? If so, why? field = true; // could already be true, but I don't care

I have code like the following:
Dim Flag as Boolean
Flag = Function1ReturnValue
Flag = Function2ReturnValue
Flag = Function3ReturnValue
Now ideally 'Flag' should only have a true value if all three of the functions returned 'True', but as it stands now it won't do that. There needs to be an 'and' or an 'or' or an '&' or something like that, but I'm confused as to what needs to be.

From 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

View 3 RepliesI have distributed a simple VB 2005 application that generally runs just fine without any installation: the user just inserts the CD and it starts via autorun.inf. The rare problem the users have is if they do not have .Net Framework 2 installed. I want to catch this error in my application, and display an appropriate message. I also want to test this on my own computer (which of course has the Framework installed). So my questions are
1. Should I be using a try-catch-end try in the form load sub, or somewhere else? and
2. How can I test this on my own computer without un-installing the Framwork? If I can raise an error while debugging, what error number should I raise?

I am importing alot of data from a text file into an access database with the code below. (From a Comma delimited text file) The problem is that I do not want to import duplicate records. I have the "IDNr" column in my access database set to "not allow duplicates" and need my code to check if there is already a record in the database before trying to import the data. Otherwise it will just give me an error or not import the rest of the data. I could do to make sure that there are no duplicates for the IDNr column?
