Select Case Block W/code
Nov 24, 2011'This program is to ask for input from a customer as to the type of lift ticket desired, whether it will be for a half 'day or full day and the total number of days desired. It will then calculate the total ticket price plus a slope 'charge of $10.00, a 10% sales tax will be added to the total of both the price and charge.'The checkboxes were designed to order one type of ticket at a time, when one box is clicked the 'other checkbox dissappears. Clicking the box again resets them both to visible.[code]
View 16 RepliesWhy Wouldn't 'Select ... Case' Execute The Code When Using A Variable
Jan 3, 2011I'm using some VB.Net code to manipulate files on my system - the idea is that the code checks if a file exists, and based on a value read from a text file elsewhere the system decides what to do... For this I'm using a 'select... case' statement to decide on the action to take. However, when assigning a value to the variable, the code doesn't even find the option to go for... Here's the VB code:

View 2 RepliesUsing Sender As A Case In Select Case Statement?
Mar 21, 2006When my form loads it adds some handles (using AddHandler) to a sub (showStatus). What this sub does is checks which control activated the sub (using sender.Equals) and displays text in the status label (status) accordingly.For this I use an If...Then statement for each possibility. There are many possibilities and my code get cluttered. Is there a way to do the same thing with a Select...Case statement. I tried: Select Case sender Case tbOne : status.Text = "blahblahblahblahblahblah" End Selectwhere: tbOne is a textbox, status is a StatusLabelIt gives me an error though, saying "Operator '=' is not defined for types 'Object' and 'System.Windows.Forms.TextBox'."Any ideas on how I can get this to work with a select case statement?

View 7 RepliesIf-Then-Else Vs Select Case ?
Jan 3, 2011I'm working on a routine that requires a significant amount of nested and daisy-chained logic. Using If-Then-Else, each logic construct would run 8-15 lines of code (quite readable) while using Select Case each construct doubles that (even with significant commentation, it gets less and less readable with each new Case).
I've read many times in this forum how Select Case is leaps and bounds ahead of If-Then-Else in runtime performance, although I can't recall any discussion of the underlying process(es) that make it so. I've also not had any luck finding good, detailed documentation on the nuts and bolts under each logic construct. What I'm working on, if the performance leap is legit, needs the performance more than the readability but if the performance is marginal then the readability is going to get the priority. how and why Select Case is supposed to process so much faster than If-Then-Else. Links to good white paper would be really nice too.

Select Case & Combo Box Value?
Jan 26, 2009I am using visual basic in VS 2008 and trying to learn how to assign a value to a word in a combo box using case select, this is my first attempt at programing and i just can't work out what to do next. So far i have two combo boxes a label and a button, i want the word, first to = 11, second = 9, third =7, fourth = 5. All it is doing at the moment is adding the list index value and displaying that total in the label. I want it to display for eg: if (first=11) and (second=9) are selected a total of 20 in the label,and so on for what ever combination is selected.

Using TryParse Within Select Case?
Nov 8, 2010I am in my programming class and we had a small program to make that would check to see if an value that was entered is a integer and convert it to a Roman numeral. I know how to properly do it by putting the TryParse into the If...Then statement. What I am trying to do is to not use an If...Then statement and go just by a Case Selection statement. If it is not possible then that is cool with me, I am just trying to think outside the box. Here is what i have done with it:
[code]....
When you do say "Case 1" it says it needs to be "Case CBool(1)." Using either "Case CBool(1)" or "Case 1 = 1" provides the same result .However the code shows no errors it doesn't do the conversion, it always displays the label's value as "I"

What seems natural to do is:

Case myRadioButton1
Case myRadioButton2
Case myRadioButton3
Case Else
End Select
I just get a 'reference to a non-shared member reference' error. It's a shame because it seems such a clean way to do this test.. Is it possible??
