VS 2008 Comparing Strings?
Aug 10, 2009Hopefully this question will have an easy answer; I've tried searching for the answer myself, but I don't know what to search for (I don't know what you would call this).

Com Interop - Equal Strings Sometimes Behave Differently?
Dec 30, 2009Example:
Dim Sh32 As Object = CreateObject("Shell.Application")
Dim path As String = "C: empcatalog.zip"
Dim sf As Object = Sh32.NameSpace(path)
-> does not work, sf = Nothing
Dim Sh32 As Object = CreateObject("Shell.Application")
Dim path As String = "C: empcatalog.zip"
Dim sf As Object = Sh32.NameSpace(path.ToString)
Clearly path = path.ToString, but they behave differently when used as COM parameters.
VS 2008 Comparing Version "strings"?
Aug 25, 2010I cant seem to think this morning.I am trying to compare version strings. These are scraped off a website...

how do i make sure I am grabbing the highest version?right now I have it checking the length, if less than 9 .. add a zero. then remove the .'s and convert to an integer. then just check. I know thats not the best and most accurate.
Comparing Strings In A Listbox?

Basically, how would I go about it searching through the listbox for "String 4" and then a messagebox coming up?
But, if it doesn't find that string an error message comes up.
VS 02/03 Comparing Strings That Contain Quotes?
Aug 18, 2011I'm trying to compare the selected item in a combo box to the items in a collection in search of a match. There is guaranteed to be a match because the combo box was originally populated from the same collection. This is the code I'm using:
[Code]....
This code works for other collections but not for this one. In this case, the loop stops after the first iteration, regardless of what's selected in the combo box. I have confirmed that the collection contains the correct data and that there is a match for the combo box options. The only difference between this instance and other instances is that the values in the collection and in the combo box contain a double quote at the end. I suspect this is what's causing the error. (To be clear, there is no error message, it's simply not returning the correct value.) I've tried various string compare methods but none of them have fixed the problem.

Comparing Large Array Lists - Matching Strings?
Apr 26, 2011I have two array list same size, depending on the information gathered by previous functions. The size of the arrays range from 2 - 45 in length, both arrays always have the same length. I am trying to match one string in one array to another string in the second array. When they match then add Item to List.
Here is my
Do Until i = Arraylenght
info = Replace(myAL(s), " ", "")
SortedArrayList(m) = Replace(SortedArrayList(m), " ", "")
SortedLine = Split(SortedArrayList(m), "Price=")
If myAL(s).Contains(SortedLine(1)) Then
[Code] .....
This code works up to an array of not more then 4 in lenght, when working larger size array then 4, the minute it get to 5 I get this Error:
Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index
Comparing Lists Of Strings - Copy And Display Elements?
Dec 20, 2009I have two lists of strings. One is a list of all students in a class and the other is a list of students in the class that completed an assignment. The two lists are part:whole. So we have two loops for copying elements and displaying them in a list box for only the students who did submit.
Dim f As Integer
f = 0
Dim h As Integer
h = 0
While (usersinclass.Count > f)
h = 0
While (usersidthatsubmittedassingments.Count > h)
[Code] .....
What I need is the remaining portion of the "usersinclass" list. (i.e. The students who did not submit). I tried an Else statement BUT with nested loops, every element is guaranteed not to match at least once, so I was getting elements that shouldn't be there. So, is there anyway to run the given lists against each other again to pull out the remaining students? (preferably with no repeats).

VS 2008 Not Two Equal Rows Consecutive?
Jul 18, 2009I'm trying to load some data from a MySQL table and sort it so two equal rows doesn't come consecutive. I've been trying to do this on the server-side, but it looks like it's impossible.

VB 2008 Loops And Comparing To 0?
Jul 5, 2010I've had no issues with this in C++, however, in Visual Basic 2008 (not sure about 2010), when I run a Do loop of any type, and run a comparison to 0, or even 0.0, the code loops a second time.
[Code]...
To my knowledge it should cancel after the 5th line, since the condition is satisfied. However it does not. Instead it runs the loop one last time.If I put in a comparison of any number higher or lower than 0, it works as it should, and cancels properly when the 5th line is written. So 1, -3, 0.0001, etc. works, so the problem lies with 0.
Now I do not know that much about the debugger, but it should be mentioned I'm running express edition, and I could not find anything that lets me see how each line compares. Nor, after an hour of searching online, could I find a single forum where this is answered (though perhaps that is due to how I worded my search).
If someone could explain to me why the comparison does not work as it should and loops a second time when comparing to 0, or even 0.0 (one person thought it was a difference in balance being double and 0 being an integer),
