Regex In 2005 For Case Insensitive Registry Search
Dec 15, 2009
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
[Code].....

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 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.
Input:
<Dockpanel DockPanel.Dock="Bottom">
<Label Content="(c) blahblah" HorizontalAlignment="Left" Name="Label2" VerticalAlignment="Bottom" Opacity=".75" Background="White" DockPanel.Dock="bottom"/>
</DockPanel>
Output:
<DockPanel DockPanel.Dock="Bottom">
<Label Content="(c) blahblah" HorizontalAlignment="Left" Name="Label2" VerticalAlignment="Bottom" Opacity=".75" Background="White" DockPanel.Dock="Bottom"/>
</DockPanel>

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 have spend a couple of hours trying to figure out why my generic Dictionary(Of String, String) is not ignoring case.Here is my code:

test.Add("FROG", "1")

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" />

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 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.

Is there any way to use Dim Str as String = "UPPERlower"Str.Contains("UpperLower") and have it return true?

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", _

If I have a list of filenames in a list, how can I do a case-insensitive lookup?
Dim files As List(Of String) = IO.Directory.GetFiles(myFolder).ToList
If files.Contains(myFileName) Then
'do something
End If
The above snippet will only do a case sensitive search.

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'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).

For example, I want to match <Tag or <TAG and replace to <tag
Here's what I did(which obviously did not work): tmp = Regex.Replace(tmp, "<(.*)", LCase("$1"))
Just wondering what are some good ways to do this?

Here's the situation: I've got a form that has
- RichTextBox
- OpenButton (to load RTF file)
- SaveButton (to save RTF file after editing)
- Textbox (for search phrase)
- SearchButton
- ExitButton
- 2 RadioButtons (WholeWord and MatchCase search)
All of them are working just the way I want them to except search features; I don't know how to write them properly. At the moment, they search and highlight only the first word they encounter. E.g. say I search for word "the" in the document, only the first "the" it encounters is highlighted. The rest is just untouched.
I understand this is because I've only got few lines of simple code as follows
If rtfText.Find(txtSearch.Text, RichTextBoxFinds.WholeWord) = -1 Then
MessageBox.Show("No results returned. Please try again.", "No matching results.", MessageBoxButtons.OK, MessageBoxIcon.Information)
End If
I did try a few other snippets I found on the Internet including While loop but they didn't work as I wanted them to, and I couldn't understand them either. What I want is, which ever search option is used, when the matching result is found; it will highlight that word and when I click it again it will move onto another word. If I keep clicking, it will highlight the same words (but located in different areas) throughout the whole document and at the end, it will send back to the first matching word. Just like Adobe Reader search.

I have a textbox with a large amount of data, but I am trying to extract only the following into an array: only 3 or 4 letter, uppercase words. The goal is to find all stock symbols within a document.
For example, in this post, if I were to type "MSFT", regex would extract MSFT because it is a 4 letter, uppercase word.

I think I have read somewhere that delegates could be used in place of Select Case but I cannot find anymore that article. Could anyone confirm and provide some sample if this is true?I've only used delegates in threading and I have been heavily using Select Case and thought I could try using delegates instead.
