VS 2010 Need To Select Value To Multiply
Feb 1, 2011I still want to be able to show my code in front of the class/receive feedback. I originally had a program that would calculate the number of calories in your alcoholic beverage.Because I was new at it, I only had one of my beverages listed. I now want to create a combobox/ dropdown menu so that the user can select a standard alcoholic beverage (I have 6 to choose from). All the beverages have different average calorie counts. Once the user selects their beverage from the menu, they can type in the number of servings they consumed (standard size). They would then push a calculate button and would receive their total calorie count. I have everything up and working but everytime I enter a random number of servings and push calculate, it only multiplies by "100" which is the average calorie count for a serving of Light Beer-- the first listed.[code]
I just added the If/Then/Elseif stuff a couple of minutes ago, hoping it would work, but it doesn't. I know this is something simple but like I said, I'm brand new but I have searched everywhere trying to figure this out. I've watch 9 tutorials so far but they all don't really pinpoint what I want my program to do.

View 14 RepliesTrailing Ampersand In .NET Hexadecimal?
Jul 22, 2011What's the trailing ampersand on VB hexadecimal numbers for? I've read it forces conversion to an Int32 on the chance VB wants to try and store as an Int16. That makes sense to me. But the part I didn't get from the blurb was to always use the trailing ampersand for bitmasks, flags, enums, etc. Apparantly, it has something to do with overriding VB's fetish for using signed numbers for things internally, which can lead to weird results in comparisons.
So to get easy points, what are the rules for VB.Net hexadecimal numbers, with and without the trailing ampersand? Please include the specific usage in the case of bitmasks/flags and such, and how one would also use it to force signed vs. unsigned.
