I am doing a search to look for a value that corresponds in my datagridview. But the problem is it is being case sensitive. Is there a way to disable that? The code I am using is below.
Supplier_List.DataGridView1.Rows(i).Cells(0).Value.contains(txtSupplier.Text)
Supplier_List.DataGridView1.Rows(i).Selected = True

Is there a way to enforce case sensitivity in VB.Net file-names?
The primary issue that I am trying to solve is the difference in how Windows doesn't care about the case of a file-name, but other tools, like Subversion, do care about the case of a file-name
I am trying to compare the contents of 2 collections in a unit test in .NET using MSTEST. To make things simple, instead of having to .Sort() and then loop through the collection and compare items one at a time, I've found the new and very cool .Intersect Extension method.
It seems to work great by doing:
Assert.AreEqual(expected.Count, actual.Intersect(expected).Count)
However, now that I have a test which needs to be case-sensitive, it breaks. I've tried sending Intersect's second parameter StringComparer.Ordinal,StringComparer.InvariantCulture, and StringComparer.CurrentCulture... no luck..
EDIT: here is the data:
Actual:
(0) "FOO" String
(1) "foo" String
(2) "Foo" String
[Code]....
It seems to be removing a matching duplicate 'foo', and a matching duplicate 'BAZ'. Perhaps there is a better way to assert collections are matching?
_EDIT2: I think Intersect() removes duplicates, which is why this is breaking. I Found the CollectionAssert Class.
I want to select one item in drop down list in ASP.NET written with VB.NET - I have values and texts in listbox like this:

i wrote small programm based on joyGetPosEx which read ION Drum Rocker commands as gamepad events and converted it to midi notes signal to MidiYoke or other virtual midi cable.With this program ION Drum Rocker xbox360 drums with cymbals can be used as midi device for PC. Also if edit source for read another command can be used any gamepad device as mididevice.If any someone have ION drum rocker drumset then try to test this program.
I have some issue with it, drumset do not transmit any commands which can be used for sensitivity of hits. But drumset have some sensitivity of hits if connected them to xbox360 console. Maybe problem in HID gamedevice driver, or joyGetPosEx?

View 2 RepliesWhat happens here is when I click on anyone of the radio buttons the text box score sets the value to either 0,1,2,3,4 but when I go the next case it goes back to 0 instead of keeping the value. I tried many different techniques while going about this none seem to work.

I would like to change the case in a Textbox to look like a proper sentence, so the first letter would be capitalised and all following letters would be in lower case.
For example:
original text: "this IS My Text"
output text: "This is my text"
It is easy to change texts/strings between upper and lower case...
vb
TextBox1.Text = TextBox1.Text.ToLower
TextBox1.Text = TextBox1.Text.ToUpper
... but how can I apply a sentence case?
I want my TextBox to make the text i enter as Sentence Case(ProperCase).. but i dont want to write any code in an event like Lost Focus or KeyPress
Just by default when ever a user enter or types in a textbox the first letter of every word should automatically converted into UpperCase
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?

I'm programming a utility for a game, and at the moment I am adding chat commands for it. They use the Select Case type, but I want to be able to use multiple conditions for 1 case.
Current

AnnounceMsg("^1No Laming
^7Laming consists of

If I have a list of filenames in a list, how can I do a case-insensitive lookup?

The above snippet will only do a case sensitive search.

I wrote my own database handling code (actually, I write T4 text templating files that generate my database code for me) and part of it takes care of converting values from a database (as Objects) to the desired types.
I have been using this generic function successfully:
vb.net
Public Overridable Function ConvertType(Of T)(value As Object) As T
Try
Return If(value IsNot Nothing AndAlso value <> DBNull.Value, DirectCast(value, T), Nothing)
[Code]....
Simple enough, but it doesn't work... The return type of the function is (and must be) T, so I cannot return a Boolean because a Boolean cannot be converted to T!
Well... It can in this case, because I specifically check that T is Boolean, but the compiler doesn't know this so it doesn't allow me to return a Boolean. I cannot cast the boolean to T either.

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.
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.
