I want to access each entered element in an textbox as an index in ArrayList. But, the problem is that whenever I enter value in the textbox, it stores all the values in single arraylist index.
View 1 RepliesI am trying to populate an ArrayList using the elements from a DataTable. I know I could do this using Loop, but I am trying to figure out how to using AddRange.Here's my code:SomeArrayList.AddRange(SomeDataTable.Rows.Item(0).ItemArray)
The problem is that I can pass the collection except for the Zeroth element.
This is the collection I am trying to pass to the ArrayList:
1. Dog
2. Cat
3. Bird
This is what I got 1. Cat 2. Bird
I am working on a 32-bit binary/hex/uint masking calculator and have run into a snag. When I attempted the following, it created an error:
For i as Integer = 4 to 126
TextBox(i).Visible = True
TextBox(i).Clear()[code]....
Since this sequence of events is in 4 different places in my code depending on a user screen selection, for obvious reasons it looks really bad. Is it possible to use indexing instead?
there are any nifty in-built .net methods that can essentially return either the number of occurrences of each element in an array, or simply return the modal value.
View 7 RepliesI am building an application to show an arrayList in a textbox and then sort the array in a listbox, I am initailizing the ArrayList via the application.
View 1 RepliesI'm trying to do is take each item from an arraylist, that is populated through a structure read from textfiles, then loop through them adding each result from the arraylist to a new line in a textbox. What I'm getting is that it's adding only the last item to the textbox rather than listing them, yes I have multiline set to true. Because of the potential size of the arraylist I have it running in a background worker. Once it's complete then I'm trying to populate the textbox. All the code is working fine to that point it's just populating the textbox correctly is my problem.[code]I've tried adding vbnewline, vbcrlf, cblf at the end of the statement as well as placing the text statement in both the runworkercompleted sub as well as in the delegate with the same result.
View 5 RepliesI develop an application in vb.net and mysql server for data storage. I have a problem in my database I have something like 5000 codes stored like code, description, quantity, price, firm. I have a function to extract all the codes from database , it takes about 4,4269 ms to extract all 5000 codes with description and everything... in an arraylist. When I want to put all codes from arraylist in a textbox autocomplete, it took about 2305,400 ms and I think this is a big problem the function to put in textbox autocomplete all the items from arraylist:
Code Snippet:
Public Sub PopuleazaTextBoxDinListaCoduri(ByVal txtbox As TextBox, ByVal list As ArrayList)
txtbox.AutoCompleteMode = AutoCompleteMode.SuggestAppend
txtbox.AutoCompleteSource = AutoCompleteSource.CustomSource
Dim valoare
For Each valoare In list
txtbox.AutoCompleteCustomSource.Add(valoare)
Next
end Sub
This is one item from arraylist extracted from database in this format :
code4993 ->description of code4993(3 buc X 234 lei)
I want to cycle through a arraylist and for each item in that list I need to create a picturebox, label1, label2 each with specific name attributes

I have a function which iterates through the TextBoxes in my form (and its child controls) and adds each TextBox's name and text to an ArrayList using a structure I called valTxtBox.
Here's a snippet of the
VB.NET
Public Structure valTxtBox
Public nome As String
Public texto As String
End Structure
[Code] .....
Now, the problem is that if I call Clear() for valsTxtBox in the getctrls() function, not all the elements get added to the ArrayList. However, if I don't call Clear() it works just fine. BTW, I'm using VS2008 express which might be relevant.
I've written a Windows application which reads the title of a Window (which is in Greek)

I'm writing a tabbed web browser for someone who is learning VB.NET, and I have got to the point where I can add/remove browser controls into tab pages, controlled by one set of buttons on the main form, but I can't handle events from the WebBrowser objects.I have tried this but it says that 'DocumentTitleChanged' isnt an event of 'Control'...
Dim browser As New ArrayList
browser.Add(New WebBrowser)
browser(0).parent = TabControl1.SelectedTab
browser(0).dock = DockStyle.Fill
AddHandler browser(0).DocumentTitleChanged, TitleChangedHandler()
I want to update the tab title with the web page title when it changes. I started using a timer to update the tabs but there must be a way to add an event handler here.
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.

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've been having problems with a really basic search routine that I have used successfully before but now for some reason does not. I have a text file that looks like this: Spindly Killer Fish, fish, spindly, aggressive, dangerous, grey, Sect.B Tank.1, 20 It is then loaded into a two dimensional array with comma separation. This is all fine and with the following nested for loops it works also, it just doesn't seem to compare the selected element with the textbox value. [Code]

What I need to do is read an ArrayList in My.Settings and add another ArrayList to it. The first think I'm trying to do is load My.Settings.Records into myArrayList. I'm not quite sure on the proper way to do this. I've tried things such as Dim myArrayList As ArrayList = My.Settings.Records, I'm not sure if I need New and I'm not sure if I need .Clone or .CopyTo.
Then I have another ArrayList myArrayList2. To get this into myArrayList I've done: [Code] Then to save it back to My.Settings I've done. My.Settings.Records = myArrayList. The problem is I keep on getting Object reference not set to an instance of an object error on the AddRange line. My.Settings.Records is definitely an ArrayList and it will sometimes = Nothing. The objects will only ever be strings.
I have a number of rewrite rules for a lot of things that I did in IIS7, like removing trailing slashes, canonnical URLs, lowercase lettering, and such. IIS altered my web.config, and everything works fine on the website, like it should. But in the Visual Studio web.config, the opening < rewrite > statement is underlined in blue, and at the bottom of VS, it says that the element 'system.webServer' has invalid child element 'rewrite'. But this is how IIS made it. I didn't do this manually. Should I be concerned with this VS error, or should I just leave as be, since it's working how it should work? Here's an example of my web.config:
