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 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?
I dislike WPF's inability to interpret text in a case-insensitive way.Are there any tools (i.e. VS plugins) out there that will take my VB .NET code and handle the case-sensitivity issues for me?Edit: Now with examples.
visual basic.net is case insensitive so it allows the coder to write without caring or remembering the casing of variables. it also relieves from the 'undeclared variable' errors if you use the variable in another case than the one used in declaration. The fact that its line termination is a line feed makes it even more readable unlike C# or c++ that need good care in the casing and contineous war with following up with the {}, matching them and figuring out which is for which.
my question is what are the advantages of c# over vb knowing that both get compiled to MSIL so there is almost no performance difference between the two languages?
I created a Web Reference (also tried Service Reference) to a WSDL that had the following node inside an xsd: <xs:element name="filter"> <xs:complexType> <xs:choice minOccurs="0" maxOccurs="unbounded"> <xs:element minOccurs="0" maxOccurs="unbounded" ref="condition" /> <xs:element minOccurs="0" maxOccurs="unbounded" ref="filter" /> [Code] .....
This wouldn't build in a VB project because VB.NET is case insensitive. I tried deleting one set of and/or, but when the XML is created, it simply ignores the selected value. I also tried appending an X at the end of one the sets which also failed. Is there a way to make this work? I also tried updating the XSD so it just had two values without success. The interesting thing to note is that default is set to "and" and while debugging it will set it to and, it doesn't actually produce the node attribute of it just generates.
I have a TextBox that need to be case-insensitive. For example, I have this. If searchTextBox.Text = "Park" Then... I need results back if "Park" is typed or "park".
I put this at the top of my project: Option Compare Text
Here is the sub that contains the process name check: Sub AC3() Dim ProcessList As System.Diagnostics.Process() ProcessList = System.Diagnostics.Process.GetProcesses() Dim Proc As System.Diagnostics.Process For Each Proc In ProcessList [Code] .....
No errors, but it only checks the lowercase hack/cheat/inject. I need it to be case insensitive when checking it.
Figured it out and tested and it works. I put, right after dim procname... procname = procname.ToLower() works great.
I've read that it's unwise to use ToUpper and ToLower to perform case-insensitive string comparisons, but I see no alternative when it comes to LINQ-to-SQL. The ignoreCase and CompareOptions arguments of String.Compare are ignored by LINQ-to-SQL (if you're using a case-sensitive database, you get a case-sensitive comparison even if you ask for a case-insensitive comparison). Is ToLower or ToUpper the best option here? Is one better than the other? I thought I read somewhere that ToUpper was better, but I don't know if that applies here. (I'm doing a lot of code reviews and everyone is using ToLower.)
I am working on a program for a client and will need a feature to search for strings from an array without case sensitivity. This currently works, but it is case sensitive. I commented out the code for readability.
' Declare array for goldSmithingExpertise and add items. Dim goldsmithingExpertise() As String = {"Alluring Earrings", "Alluring Ring", "Alluring Belt", "Howling Staff", "Dawn Ring", _ "Melancholy Earrings", "Melancholy Belt", "Melancholy Ring", "Jubilant Ring", "Jubilant Earrings", _
I've been using text.indexof() to see if a string is located inside another string, however is it it possible to do a case sensitive/insensitive search option? I've been looking around Google and not having much luck with it.
A huge bonus would be if it could count the number of occurrences inside the string!
I am searching through files and only want to include files with certain extensions. Right now I have what is below but it would be stupid to do it that way for 3 or more file types and it isn't completely case insensitive.
If ext = ".jpg" Or ext = ".JPG" Then
I want to check for .jpg .gif .png all case insensitive.
I've recently learnt that Regex class maybe used to develop case insensitive searches. I have a registry search program that will return only the exact matches from the registry. I need to make it case insensitive. how to do that using regular expressions in vb.net 2005. Im posting my code below:
Sub SearchSubKeys(ByVal root As RegistryKey, ByVal searchKey As String) Dim matchtype As String = Nothing Dim str(5) As String
I'm having trouble when trying to do a case-insensitive query on a table. Right now the query is:
txtQuery = "SELECT Status, RankingSearchEngines FROM [tbl-DATA-Client-Keywords] WHERE [Client-ID-Code] = '" & clientNo & "' AND lower(Keyword) LIKE '" & sField(0) & "';"
The actual query executed is:
SELECT Status, RankingSearchEngines FROM [tbl-DATA-Client-Keywords] WHERE [Client-ID-Code] = '1402' AND lower(Keyword) LIKE 'flyer printing';
I have an entry 'Flyer Printing' in the database, and this query works perfectly without the case-insensitive check.I'm not sure if this is an OleDB issue, as I've never had this sort of problem with SQLPlus, or anything else
The exception being thrown is:
IErrorInfo.GetDescription failed with E_FAIL(0x80004005).
Question: I use the bidirectional dicionary class I found here:Bidirectional 1 to 1 Dictionary in C#The problem is, I need this - case insensitive (StringComparer.OrdinalIgnoreCase)I wanna extend it to cover the IEqualityComparer constructor.I've converted it to VB (works like a charm), but I have trouble implementing the comparer 'transfer'.The problem is, in the parameters I have:ByVal x As System.Collections.Generic.IEqualityComparer(Of TKey)But the dicionary secondToFirst is of type TValue, TKey, which kills my IEqualityComparer, which needs to be of type TValue instead of TKey.

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 had to change the given code from If Then to Select Case, and this is what I came up with. But when I run the program, it does not work and gives me zeroes instead of the correct information.
Public Class MovieInfo Private wkndBox, screens As Integer Private title As String
Public Function TitleCase(ByVal strIn As String) Dim result As String = "" Dim culture As New CultureInfo("en", False) Dim tInfo As TextInfo = culture.TextInfo() result = tInfo.ToTitleCase(strIn) Return result End Function If I input "TEST" into the function above. The output is "TEST". Ideally it would output "Test". I also tried the code snippets from this post to no avail: Use of ToTitleCase.
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.
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..
I want to group items from a linq query under a header, so that for each header I have a list of objects that match the header title. I assumed the solution would be to use ToDictionary to convert the objects, but this allows only one object per "group" (or dictionary key). I assumed I could create the dictionary of type (String, List Of()), but I can't figure out how to write it. As an example I have written a simplified version below.
