VS 2008 - Take A String Of Variables With A Common Delimiter And Break It All Back Out Into Separate Variables
Dec 11, 2011Last year (2010) I came across a FANTASTIC command that allowed me to take a string of variables with a common delimiter and break it all back out into separate variables (possibly an array) with one statement.
[Code]...
As long as the delimiter was a unique specifiable character, this one-statement command could break it out into elements. my memory and point me in the right direction.
Shared Variables And Garbage Collection?
Feb 21, 2012I've been doing some reading on garbage collection in .NET and I was hoping for some clarification. So, as I understand it if I declare a public shared class variable, the GC will never get rid of it. Is this correct?Also, what then of private variables? Take the following example:
public class myClass
private shared myString As String
public sub ChangeString(newString As String)

How To Convert Collection To String
Jan 3, 2012I am trying to convert a collection to a string. When I am done, it should look like String() = {"File1.Tif", "File2.Tif", "File3.tif", "MergeTiffImages.Tif}. Here is what I have so far.
Dim FileArray(0) As String
Dim Count1 As Integer
Count1 = 0
For Each k In S
ReDim Preserve FileArray(Count1)
FileArray(Count1) = """" & k & """"
Count1 = Count1 + 1
Next
FileArray(Count1) = """MergedTiffFile.Tif"""
I am getting the error "Index was outside the bounds of the array." because FileArray is a string and not an array.
String Breaks To Collection?
Apr 23, 2009heres my situation and what i need done, will follow with code that sort of works
1. read a text file into a string2. for each word in string, append word to collection3. sort collection and remove duplicates4. check collection against existing collection and remove found items5 output final collection to text file
heres the code i have now, it inputs text to rich text box, replaces spaces with enter's and exports to text file, the reads file line by line to a collection and sortes and removes duplcates but takes way to long, mises words, locks up, ....it would also be helpful to remove all numbers and puntuation (anything not a-z)

Apr 8, 2012I'm sure you've all seen this a lot before (in a variety of forms) but I think (hope) it's a bit different. <Not actual names of variables>I have two forms (form1 and form2). Form1 has 2 class-level variables, a string (m_String) and a collection(colCollection).Inside form1, the collection is loaded using a key. With an if-statement, the collection is matched to input (from a combobox) through the matching key.The chosen string from the collection is then passed to the m_String (confirmed with MessageBox.Show(m_String)

Now I have it so when you click the add button it will put the URL in the string FavList, and place the URL in Listbox1 however I have no idea how to save it, and load it.
So the next time the user opens it, it will have the URL in the string and URL box, so when they click the URL in listbox1 it will redirect the WebBrowser. I think it works like that already I just need to know how to save it, and load it.

Jul 7, 2009The code below reads each line from a file and if the conditions become true it adds the contents of the file from the particular line and after into a string collection (i.e. the All contents).
