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).

As I have done the little research and found that the secure connection strings would be encrypted the strings and input the strings in app.config, so I would have to make a change in the app.config
To change from this unprotected app.config:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<configSections>

The code have been built to a guy who known as Nick J. Fessel. I am not too sure if it very secure to use it so. Do anyone know that if the connection strings is secure or not?

[2005] Populating Textboxes From Array Of Strings?
Jan 22, 2009this is how I set up my data object for a file parser. (
Dim mytable As New List(Of String(,))()
mytable.Add(New String(4, 16) {})
and it loads mytable like this:
mytable(x)(y, i) = sToken(i)
Let me explain the indices, I have a form with a tab control. In mytable,x is the tab number. Each tab has up to 5 groups which is y. Each group has 17 text boxes, i.Each group also has 17 labels.I started looking at Me.controls, and looking at control properties like tabindex for some way to iterate through the textboxes and mytable to load the textboxes.
so I started with:
for x = 0 to 31
msgbox(group1.control(x).text
next x
and I saw how all my objects are not in sequence as it descending halfway through my label controls, then switched to my textboxes, and then seemingly finished randomly. I am at a total loss without the old index property and what I want to do is something like (forgive my syntax)
Form(0).Tab(x).group(y).textbox(i).text = mytable(x)(y, i)
I was thinking of manually setting the tabindex of all textboxes in group1 to sequential order to try something like:
group1.component.tabindex(i).text = mytable(x)(y, i)
To me this is fun and challenging, but also very frustrating and makes me miss coding in assembly As I can't seem to find any reference to the tree structure of accessing components indirectly, if that makes sense.
VS 2005 Writing 4 Or More Strings To A Single Line In A Text File?
Sep 22, 2011I've got my self in to a pickle here.I'm trying to do something I used to do in basic? At-least I think you can do this in Basic, you know Qbasic,What I'm trying to do is put 4-8 strings on to one line separated by a comma.Example might be:
writer.writeline (bob1, bob2, bob3, bob4) Out put might look like Test, Test2, Test3, Test4
I'm tried looking in to formatting of writeline/write, but I didn't get any where with it.
Also if this is possible- I would like to be able to read it just like :
reader.readline (Rbob1, Rbob2, Rbob3, Rbob4) If anyone cold just point me in the right direction, I'm sure I can figure it out - If not... Well I will ask another question.
VS 2005 : Create A Source To Get The Strings From The Text File Using ReadLine Method?
Aug 22, 2010I need a bit of advice. I am working on my project with the listbox. I know how to create a source to get the strings from the text file using ReadLine method, but I have no idea how to split the strings in the text file by on the third commas and ignore the other strings while select with the matched strings on the listbox for each row.Here it is an example listbox Here it is an example items on the listbox
random item 1
random item 2
random item 3
random item 4
random item 5
And here it is an example text file.
example strings one, any strings 1, any random strings 1, other strings 1, final end of strings 1
example strings two, any strings 2, any random strings 2, other strings 2, final end of strings 2
example strings three, any strings 3, any random strings 3, other strings 3, final end of strings 3
example strings four, any strings 4, any random strings 4, other strings 4, final end of strings 4
example strings five, any strings 5, any random strings 5, other strings 5, final end of strings 5
The listbox is display the list of an example items, so if I select the "random item 1" item on the listbox, it read the strings through in the text file on the first line to get the strings on the third commas in the same line which it is (any random strings 1) to split it while ignore the other strings (other strings 1, final end of strings 1) that come fourth and fifth commas. So, if I select the "random item 2" item on the listbox, it read the the strings through in the text file on the second line to get the strings on the third commas in the same line which it is (any random strings 2) to split it while ignore the other strings (other strings 2, final end of strings 2) that come fourth and fifth commas and so on...That is what I am trying to achieve by select the each listbox item to get the correct strings for each line in the text file that come on the third commas while to ignore the other strings.

Jul 1, 2009I have a SQL 2008 Express database, which have following tables: [code] Now I need SQL query to search for word (i.e. Beyonce Halo Music Video) against these tables.
-For Title exact phrase will get 0.5 points
-For Description exact phrase will get 0.4 points
-For tags exact phrase will get 0.3 points
-For title all words will get 0.2 points
-For description all words will get 0.2 points
-For title one or more words will get 0.1 points
-For description one or more words will get 0.1 points
And I will show these videos on basis of points. What will be the SQL Query for this? A LINQ query will be more better.

In a DataGridView, I would like to display (no edits) data coming from multiple tables in my database.A second Grid (different data, still multiple tables) will need to allow editing and saving of data.I understand creating a View in the database and using that as a source for the DataGridView.I also assume that there are ways to query and create a data source for the Grid totally within my VB program.Would someone explain the consequences and implications of the different approaches?
