Find In List / Remove Item And Ignore Case Of Characters In String
May 20, 2012I'm having issues with finding something in list, and removing the item, ignoring the case of characters in string.
The code goes:
Dim listItems As New List(Of String)
Dim pattern As String = "AbC"
Dim array() As String
array = {"ABC", "abc"}
listItems.AddRange(array)
Here I'd like to remove all items from listItems, that are abc, no matter what case single characters of item are, including mixed case items. So in this example, every items should be removed
listItems.Remove(listItems.Find(Function(r) r = pattern))
If I change pattern to match the case of item, then item #2 gets removed:
pattern = "abc"
listItems.Remove(listItems.Find(Function(r) r = pattern))
How can I find item in listItems, ignoring the case characters in pattern?
Way To Concatenate List Of Strings Into A Comma-separated Strings, Where Strings Are Members Of An Object?
Oct 16, 2009Say I have a List(Of Tag) with Tag being an object.

Dec 12, 2010[Code]...
For each character of this string I want a new character out of the string and then remove the character from the list of characters that still maybe used for other characters. It may not get the same character, you could basically just call this encryption, but it's not what I am making. I don't want to waste my time doing this one hour while VB can do this for me in <1 second.

View 3 RepliesPrepend A String To All Strings In A List Of Strings?
Aug 5, 2010I have a list of strings. For each string in that list, I want to prepend another string. I wrote a method to do it, but I was wondering if there was something already in .NET I could use to do this. It seems like something that could be built in, but I was not able to find anything.
Here is the method I wrote:
Private Function PrependToAllInList(ByRef inputList As List(Of String), ByRef prependString As String) As List(Of String)
Dim returnList As List(Of String) = New List(Of String)
For Each inputString As String In inputList
returnList.Add(String.Format("{0}{1}", prependString, inputString))
[code].....
It works, but I would rather use built in functions whenever possible.
VS 2008 Using List Of Strings Or Array Of Strings?
Oct 16, 2009I'm migrating from VB6 to VB.NET, in hence my questions below:
I have to write a function that returns array of strings.
How can I initiate it to empty array? I need it since I have to check if it's empty array after it returns from this function.
Is list of arrays better for this purpose? If I use a list - Is it empty when it firstly defined? How can I check it it's empty?
VB Strings Exceeding 30 Characters?
Jul 24, 2009On Visual Studio 2008 I am running into problems with strings longer than 30 characters, which become blank. My context is slightly unusual (perhaps) - but I dont see why it should not work.I am calling a VB2008 script from C++ using the COM interface [URL].. It works fine with integer and real arguments, and with strings up to 30 characters long.(see below - the example above is easily generalized to arguments as String, in which case the C++ code declares a BSTR object and uses L"xxxx" to set the string to "xxxx").
Surprisingly, I get a problem if the C++ string exceeds 30 characters in length - the string received by the VB routine becomes "" , ie, completely blank.I checked and this is not just a limitation of the debugger viewer - it really is "". However there is no problem with local strings exceeding 30 chars - the problem appears in passing of the argument, both byVal and byRef.

Copying Strings - Illegal Characters In Path
Jan 28, 2009I have a program where I copy strings from one file to another. I then create folders based on the strings. It works great 99% of the time. Once in a while I get this error:
Illegal Characters in Path
Here's the line of code where it happens:
If Dir$(txtSaveLocation.Text & "" & name1 & "" & name2, vbDirectory) = "" Then
It is just checking to see if the folder exists yet or not.
When I move my mouse over the variable "name2" the value shows up as
"test name 2
That's right, no closing quotation marks. How is this possible? If I manually add the quotation marks while in debug mode and restart execution the code works fine.
I do have a function to strip out illegal characters first too:
For loopCTR = 0 To strip.Length - 1 'strip characters out
name2= name2.Replace(strip.Substring(loopCTR, 1), "_")

Spliting Strings Special Characters In Regex?

The field1 and field2 still have a trailing "&|" chracters.How do I check if the field1 and field2 have these trailing characters? How do I delete them?PS - I have tried "&\|:" as the delimiters in the split function which did not work.

VS 2010 - Any Way To Remove Illegal XML Characters
Feb 15, 2012I am retrieving string values from a table and then encode each term to make a httpwebrequest to an api. It works fine and the terms allow for foreign characters like japanese/arabic/chinese etc and these are inserted fine. The problem occurs when some of these terms contain weird characters and that is when the request is bad. The only reason it is bad xml and the template I follow gets invalid are when these characters are present. I use the
system.securityelement.escape
And also
httputility.htmlencode
As part of my cleanup. One of the weird characters ends up appearing as a space but it is not since the trim(term) does not work and when I look at the xml in visual studio it looks like an ' &' with arrow pointing up attached to it. It does not appear after I pasted it here.It appears as a line feed or carriage return and I have tried to remove that too. Anyway is there some way I can ensure that these sort of characters are removed and if I were to use the binary values like <32 invalid, will foreign characters then get excluded.
temp = temp.replace(vbCr, "")
temp = temp.replace(vbLf, "")
temp = SecurityElement.Escape(temp)
