Converting Numbers To Roman Numerals And English Written Equivalents?
Mar 8, 2012I need to write a program to convert in a textbox a number to its roman numeral and written english equivalent. I can write everything except how to get the program to recognize the numbers and convert it into what I need it to.
This is what I have so far, and I'm not completely sure if this is even right, but I can't figure much else out. I've talked to other people who know about this and they aren't sure how to go about it, and my book isn't a big help either.
I would really appreciate any and all help than anyone could give me. I just don't know what else to do and I've been stuck here for a few days trying to learn how to do this...

Convert Text From Mac OS Roman To UTF8?
Sep 28, 2009I've encountered an incredibly frustrating problem during my work with a function to extract META-data from images.
When reading data from a file created under Windows in any kind och charset there is no problem at all, but when reading from files created under OS X i can't convert it to utf8.
The problem only occurs on chars like 'å','ä', 'ö' and some other chars that i rarely use.
Is there any way of converting chars on-the-fly serverside?
I guess i need a function to determine the actual charset as well.
I've tried numerous ways of converting with HTMLEncode/Decode and URLEncode/Decode without ANY result at all.

Using 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?

Oct 31, 2011I 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).

.net - If Case Statement Throws Exception "case Else" Start Working?
Jun 19, 2012It looks like impossible but...
Try
Select Case command
Case 1
smth()
Case 2
[code]....
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

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.
Make A 'like' Statement Or Use Some Kind Of Wildcard To Make The Statement Not Case Sensitive?
Jul 11, 2010I'm building a listview search feature in my app. (See the code below). It works really well, except if you search "T" then the code removes all items, if you search "t" then it removes every item except for those starting with "t". Is there any way to make a 'like' statement, or use some kind of wildcard to make the statement not case sensitive?

Jump To A Next Case Statement?
Jun 20, 2009I am not sure what to do with the following. The code below reads from a massive list of phrases, checks for a certain conditions and if all succeed a) adds the output to the new_question list b) keeps the value of the variable incremental to "level_0".
If the fourth "if statement" fails, the code changes the value of the variable incremental to "level_1" and jumps to a second case statement. The problem is that for certain input the code fails form the "third if statement" and execution refuses to jump to "level_1" (bacause the fourth "if-statement" must fail as well). I tried moving the "incremental variable" between the third and the fourth "and if" but since the code reads from a list of phrases even if it returns true, execution jumps to level_1 (as some phrases fail from the third "if statement"). I hope I am making sense

C# Switch Statement More Limited Than .net 'case'?
May 4, 2011I was reading an interesting article here and it made an interesting point about the 'case' statement in vb.net vs the 'switch' statement in C#, which I've pasted below:The following Visual Basic Select Case statement can't be represented in C# with a single switch statement:
Dim Condition As Integer = 55
Select Case Condition
Case 1, 3 To 5, 10, 12, 14, Is > 50
[code]....
I've always found the switch statement in C#, with dropthrough and consequentrequirements for a break in each case, to be a bit unwieldy. Is there any reason they haven't enhanced the switch command to allow these situations? W
EDIT AFTER CLOSE: I'm surprised this was closed, really. With the number of extension methods and helper classes I've found online for other things, I thought an enhanced 'case' would be a good chance. I somewhat hoped a luminary such as Jon Skeet may have commented on the background reasoning, rather than the individuals below who've obviously thought 'religious debate' as soon as more than one language is mentioned.
