Compare Returned Value Against A List?
Nov 6, 2011
Im still doing some amatuer programming, but now in .net and Ive come here with a question that I cant seem to find an answer to... Basically, Ive got a program im writing to interface into my companies AD and return some values, which then trigger other events etc..
The problem Ive run into is trying to find and easy way to compare the returned value when against a list of possible combinations (16 possibilities to be exact), and if its one of them then all good continue on but if not then I need to throw an error and exit sub.[code]...

I have a problem with a For Each Loop that doesn't make any sense. The For Each Loop returns values from a list which are Memory Ranges for a given device. When I check the count in the list it returns 3. The For Each only returns 1.
Here's my code:
Private Sub DisplayDeviceResources(ByRef lvwResources As ListView, ByRef intClassIndex As Integer, ByRef intDeviceIndex As Integer)
Dim curDeviceClasses As New DeviceClasses
Dim lvwItem As ListViewItem
EnumerateResources()

how to add a string item to a text box, returned from another form that has a list box?
I have two forms. on the first form I have a button which calls another form that has a List Box.
When I select the value from the list box and click on the apply button then the value should be
passed to the first form that will also have a text box. The text box should contain the value of
list box.

I am currently writing unit tests for an application near completion (before management looks at it and turns it inside out). I am testing the business layer and a method is set to return a datatable of all "GroupID"s, which are simply an integer to represent the group that a user belongs to.
I'm assuming the best way to assert on this unit test would be to assert that the correct groupIDs are being returned from a controlled test database. However, I'm not sure how to assert on a datatable. Is the only (and best) possible way to accomplish this to simply loop through the datatable until it's empty and add each value to an array of integers? How would one go about asserting on this test?

I have a program that will compare an array of grocery list items glist and an array of coupon item clist.When I compare the two and if there is a match somewhere in the array I want to have a picturebox visible.When there is no match, I want the picture box not to be visible. [code] The code seems to work great until I come to the else statement.When the code finds a match it displays the picture box and the msgbox without error, but as soon as the message box is cleared, even though i've input it as an ELSE statement, the picturebox goes false again.Does anyone have any idea of how I can "hold" the picturebox to stay visible while the match between the arrays exists?

there's a list-box with items, and say you want to modify an item in the middle of the list. You select that item and click "Modify" button and a new form appears with the previously selected item data from first form ready to be modified in a text-box. After modifying and clicking Ok the second form suppose to return that modified string to the first form and insert the modified string into the same spot instead of the originally selected item, so it looks like it was edited to the user.

I have two lists with strings as follows
list1=[Information,want,wall,east]
list2=[castle,information,want,wall,fortification]
List 2 is bigger than list 1. I am trying to compare each item of the list with each other as follows. The problem is that not all items are compared since Index1 <> list1.count. If I take this out I am getting an error ("index our of range").
For index1 As Integer = 0 To list2.Count - 1
If index1 <> list1.Count Then
if list1.item(index1) <> list2.item(index2) then

So in my Textbox I have a list of (folder) names, such as:
Folder1
Folder2
Folder3
I want to compare THAT list to another folder somewhere in someones documents (no specific folder). So let's say we compare it to the 'Arts' folder, which contain these folders inside:
Folder1
Folder2
I want to put all of those folder names in the Art folder into a list. And then I want to compare the folder names in my Textbox to the folder names in the Arts folder, and Folder3 is missing in the Art folder, so I want the textbox to contain:
Folder3
...to tell you that you are missing Folder 3 in your Art folder.

I have 2 lists of classes with thousands of elements. Each class has the same structure.
I need to synchronize the 2 lists by comparing the version, the dateandtime and if they have been labelled to be deleted in one list.
is there any trick to make this very long process as fast as possible apart from splitting the work on threads?

I have 4 string lists as follows
Dim input_list As New List(Of String) Dim input_POS As New List(Of String) Dim trigger_list As New List(Of String) Dim trigger_POS As New List(Of String)
I want to compare the contents of the input list (containing words (e.g., want, the) etc. to the ones of the trigger list (containign again words) and if a same entry (i.e. word) get the POS for both input word and trigger word from the relevant lists and put them into a property list. For example
input list (want, the, right)trigger list(want, there, wait)input list POS (verb, article, adjective)trigger list POS (verb, pronoun, verb)
Output property list (want:verb, want:verb) (only want is common between input and trigger list). Then I need to conduct a test between the two property items for similarites. If they are exactly the same, the code should output a confirmation "i.e., Yes" into a textbox. If not the code should output a "No" plus the contents of the property list into a textbox.

This is a 2 part question about list comparisons. I see lots of threads on comparing two separate lists, but I need to know how to compare values in a single list.
Part 1:I have a bunch of string values that I am first splitting and then adding to two separate lists. The strings look something like this... 3-ABC, 6-DEC, 11-RFG, 6-ABC, 12-ABC, etc... So, with the code below(vb) I am splitting the numerical portion of the string and putting it into myLeadQtys(saved for later). I then take the rest of the string and put it in another list (myLeadVals):
Dim myLeadVals As New List(Of String)
Dim myLeadQtys As New List(Of String)
Dim strMtextValue As String

I have a question about comparing values inside of a List. I have a single list of strings. Inside the list are multiple values. The values are arranged so they can be dumped into a spreadsheet.
Example:
Private ListOfStrings As New List(Of String)
ValueA(0), ValueB(1), ValueC(2) 'These three values are the same as the three values in the 4th "row" below
ValueD(3), ValueE(4), ValueF(5)
ValueG(6), ValueH(7), ValueI(8)
ValueA(9), ValueB(10), ValueC(11) 'These three values are the same as the three values in the 1st "row" above. Since this is a duplicate, I need to add a "count" of value 2 and then delete the values of this row from the List. Etc...
Each line above represents a "row" in a spreadsheet. All three values in each "row" have the potential to be the same. So, I need a way to A) Compare and count all of the common "rows" (using only the first value from each row) and B) If common "rows" occur, I need to delete all but one row from the List. ListOfStrings.Remove ?

I've build a list of Strings from files. The list itself is working fine (tried it by having ListBoxes and other controls loading its items from there just to make sure that this is not the issue). Now, I am using this list of strings to compare a Text in a TextBox1 while typing to determine if this TextBox1.Text already exists in the list. I am using the following code (where "s" stands for my List items):
Private Sub TextBox1_TextChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles TextBox1.TextChanged
If TextBox1.TextLength < "1" Then
Button6.Enabled = False
ToolStripStatusLabel1.Image = My.Resources.pic_Add_Warning
ToolStripStatusLabel1.ForeColor = Color.Red

unordered text file of 3 columns to assign into 2 arrays. I've been given a graphing component which expects a two dimensional array for a scatter graph for the set of values in the last column.
How would I parse through the list given an indexed array of 215 possible 'zone alarm locations' and if an alarm log list item, of which there can more than one for any given zone location, compare in the two dimensional array any previous value and replace it with the higher valued one? The following are my declarations for the 2 arrays. It isn't clear to me why the array for the scatter data was defined as (999,1) knowing there are only 215 possible x values (alarm zone locations)

In an Word addin, I'm using
this.Application.ActiveDocument.Words;
to get a list of all the words in the curret document. Now when I parse this list, I found the ,, . and are also in this list. Why is Word considering these words? I also looked at the word count in the status bar and that was wrong too, as for 7 words in my document the status bar shows 9 words.

I have two List(Of String) both containing several hundred thousand results.
Private Function AddUniqueFiles(lNewFiles as List(Of String)) As outList(Of String)
Dim aCounter As Integer = 0
Dim files As New inList(Of String)
[Code]....
However the time it takes to do this comparison can be very long indeed - is there a better way of doing this type of comparison... All I am trying to do is add values from List2 in to List1 which are not already present in List1 - So in effect adding new Unique values found in List 2 in to List 1. I am only looking for performance improvements - nothing else.

I know this topic is all over the place, but I am not doing an INSERT, UPDATE, DELETE. My statement is a plain and simple SELECT statement and so far has worked with 116 different items in my database until I got to one.
I have a search engine and am going through every single product in our database to add information to it. This is all done through the website, but when I search for ProductID 331 and click on it, it goes to the error page that says Subquery returned more than 1 value. This is not permitted when the subquery follows =, !=, <, <= , >, >= or when the subquery is used as an expression.
It doesn't make any sense to me that the website would error with only this one product. This is the statement I am using. Does anyone know why 1 product would be causing this error?

So how to put getFruitColor in k, how to correct it to save the k value and give me output as dictionary of fruit and k value.

Why this code doesn't work? It returns an unexpected value actually total = 0.
total = Cscore(TextBox1.Text) * CDbl(TextBox2.Text)
When trying this
total = TextBox1.Text * TextBox2.Text
It returns the expected value but I need to pass textbox1.text to the function to get the desirable value
The function is this
Public Function Cscore(ByVal score As Integer) As Double
Select Case score
Case score = 100
Return 5.0
Case score >= 95
