I need to add Functions for the Case 10 and Case 13 in this code. The code in each select case needs to be moved to the two functions which then returns the code once its called from the Sub Main section. But I am having a really hard time figuring out what exactly gets moved to each function.[code]I'm not sure what exactly to put into the individual Functions and how to change up the Sub Main section.
i have a program using a select case to convert letters to special charaters. My question is how can I get the code to read upper and lower case letters without having to put the upper case letters in my select case statement. Example: Part of my code is
When 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?
Firstly Case 2 runs. Throws exception. And right after this debugger shows that next processed statement is Case Else. Only after Case Else throws own exception Catch block start working. I've never seen this trick. Why can this happened?I'm sure the block is entered once (not like this:first enter hit Case 2 and second hit Case Else).
Update:-To Matt Wilko. Thank you for answering. I've switch to Strict On in Options of VS2010 but nothing has changed. Command is variable, not function. Watch tool shows that on each step Command is the same ( Command = 2).
Fixed. Yeeaaaahhh. I simplefy code to Try Select Case 2 Case 2
[code]....
and change project to Console app. This works as I mention. The fix was in Release mode. I was debugging in Release mode. When I switch to Debug mode everything goes as it should.
I have coded a case statement that changes the background colour of a panel. [code]When the code is run, it works for the case of colour1 that is NOT 1 or 2. However, when the colour1 is 1 or 2, it is supposed to pick a number from set array and run another case statement. Instead, it only picks the last value (for 1, this is 5, and for 2, this is 7).
Only problem is that it is using a access database that is coming from "my documents" and when I debug it pulls up the database that is finished. When I run my published program, it uses the database that isn't finished. Why is it doing this?
I'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.
I have a macro that uses "If Then" to choose what macro to run based on the ActiveCell. I would like to use the Select Case method instead. How would I change this code?
Private Sub Workbook_SheetChange(ByVal Sh As Object, ByVal Target As Range) Application.DisplayAlerts = False Application.ScreenUpdating = False
Question is, I basically wrote a Rock Paper Scissors game in VB.NET using If statements and wondered how exactly I would try and work this into a Select Case instead.Professor was pretty awful at teaching things and didn't let us know until today that it had to be Select Case(its due tomorrow
I am using the contains method to look through an array to find matches, however I notice that when I use it it is case sensitive. Is there another method I can use to do a case insensitive search or some way to modify the contains method to search case insensitively? [code]

i have a program, three radios, and 2 check boxes. the Radios use a constant value and do a multiplication. check one applies a discount. no problem.

very convoluted using if statements. and the output is often wrong(i know this is a logic error) i can not find the fault.
would it be easier to use case statments. can and will post code if requested. as it is in if then format currently it is rather long. Sometimes the answer is so blindingly obvious i fail to see it.

I am using this code to get a list of files in a folder:
Dim files() As String = (From file In New IO.DirectoryInfo(myFolder).GetFiles Where file.Extension = ".exe" Select file.Name).ToArray
This works fine, but the problem is that it selects only files with the extension of "exe" & skips files that have an "EXE" extension. Is there any way to make it case-insensitive, to make it return any combination of upper/lower case letters in the extension?
