ArrayList Search For PART Of String?
Jun 10, 2010
I have an ArrayList, and i wish to search it for a specific part of a string. Like the InStr() function.I can only find the WHOLE string. The ArrayList has strings like "This=Is A String", so if i do a check with ArrayList.Contains. It will only search for the whole string, and not something IN the string. Perhaps i need something like Starts With .
Code:
dim wordArr as New ArrayList
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
If wordArr.Contains(TextBox1.Text) Then

I have a puzzleing situation where only 120 of 151 colors defined in ColorList(i) display.
In the following code, btnsetup_click assigns 151 colors to a matrix of rectangles in a picture box. When 1 of these rectangles is clicked, it assigns the color to btnPen or btnBrush, depending on a left or right mouse click. Hovering over the rectangle displays the name of the color in label 'ColorOver'.
This all works fine except only the colors 0 to 119 from the array are actually displayed in the picture box. Yet, if I hover or click over the missing colors, the color name is displayed and the button is assigned the color that should be displayed.
Dim ts As Integer = 25 'sides of toolbox squares
Dim tc As Integer = 24 'Tool columns
Private Sub btnSetup_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSetup.Click

I have an arraylist (arrFirstArry) which I use to populate another arraylist (arrNoDuplicates) preventing any duplicates from being added. This works fine. What I would also like my code to do is prevent adding any partial values which may exist from being added. i.e. my array is like this

I have the following class
Code:
I create thousands of this class and save them in an ArrayList. How can I use ArrayList.IndexOf to search for a member (ID in my case).
Should I create an ArrayList for each member and increase them together then use ArrayList.IndexOf with one of them and use the returning index to get the other values from the other arrays?

I am new to VB.net and I am trying to work out an exercise from a book I am reading on VB. Basically I am storing some book information in a hashtable using a class called Book to store the book information. I am trying to work out my Search and Display All procedures. My Search will work for the first value in my arraylist but not for any other values. I even added the ISBN to my book class to try and use this as a search point. The ISBN is used to pull the item from the hashtable as well.
In the main code I am having problems with the ButtonSearch and ButtonAll.

I'd like to modify that to be able to put part of the name and it find it. example: Search for Banana Apple pie what it finds is 1743 = Banana Apple Pie Also I'd like when clicked the item from the listbox is displayed in a text box. If I use textbox.text = moblist.items(i) it only shows it when I search and not when I click. I've tried textbox.text = moblist.selecteditem but it does nothing?

I want to be able to:
1) save the screen as an image
2) use this image and search for a smaller image inside of it (pixel sequence)
Basically, I need the program to detect when an image comes onto the screen.NOT a pixel color at a certain coordinate, it is similar to this but instead of one pixel, it should detect multiple ones.is there any way I can put the image I want to detect in a picturebox, and it will go look at that image and keep checking to see if it exists on the screen?I have it working for pixel detection (only 1 pixel), but it isn't very reliable as there could be many other instances of this color on the screen.

I'm trying to use an arraylist as the parameter to String.Format.
msg = msg & String.Format("<td>{0}</td>" & _
"<td>{1}</td>" & _
"<td>{2}</td>" & _ [code].....
But this code throws a FormatException
Index (zero based) must be greater than or equal to zero and less than the size of the argument list.Am I wrong that it's possible to use an arraylist?

Basically, Im running an SQL query to the database, which obviously returns data in their fields. What I want to do is add each record into an ArrayList and split the string based on fields. I.E
CustomerID,Surname,GivenName etc
How do I go about this? so far I have:
alstData.AddRange(sLine.Split(","c))
sLine = the record from the database.
This doesnt seem to work, it just display's the data in one line with no split such as 20205SmithJohn?

Say if I have an arrayList, AL, that have the following sentences:
AL.item(0) = "This is a brown fox."

Is there an easy way to search "cat" in the arrayList and index 1 will be returned?

I've got some code that creates a list of AD groups that the user is a member of, with the intention of saying 'if user is a member of GroupX then allow admin access, if not allow basic access'.
I was using a StringCollection to store this list of Groups, and intended to use the Contains method to test for membership of my admin group, but the problem is that this method only compares the full string - but my AD groups values are formatted as cn=GroupX, etc....
I want to be easily able to determine if a particular substring (i.e. 'GroupX') appears in the list of groups. I could always iterate through the groups check each for a substring representing my AD group name, but I'm more interested in finding out if there is a 'better' way.
Clearly there are a number of repositories for the list of Groups, and it appears that Generics (List(Of String)) are more commonly preferred (which I may well implement anyway) but there is no in-built means of checking for a substring using this method either.
I've settled on using a List(Of), and I've borrowed from Dan's code to iterate through the list.

What I am doing is iterating through all the groups that belong to the top group (Generic reports). Then I take advantage of the GroupPrincipal.GetMembers(True) which will recurse through a given group name. I test to see if the user exits under that group and if true I put the group name in an arraylist.
I use the for each principal in GroupPrincipal.GetMembers to loop through each returned user to see if they exist.
Is there a way to put all the returned users Principal.Name from a given group in GroupPrincipal.GetMembers into an ArrayList? This would allow me to to use Arraylist1.IndexOf to search for user. Which would be much faster then iterating through a returned list using the for each construct.
Sub RetAllMbrs(strUser As String)
Dim oPC As PrincipalContext = GetPrincipalContext() '<- this is function somewhere else in the code

I should be able to get result back as long as there's a match in the parameters. If I use Function Contains (q.FirstName & " " & q.LastName).Contains(employeeName), I will not get any result back if employeeName is "John Clark" Function Contains looks only for next words from left to right. It doesn't match a single word at a time. So that's why I used this in the Linq to SQL:
