View 4 RepliesI need to know what would be the best choice of array to use given the following specifications. This array's size will be predermined upon the loading of the appication. All I want to do is be able to add values to this array and replace preexisting array items with new values without the array changing size. Someone suggested that I use a Dictionary Array Object? I would appreciate any suggestions.

I need this to be done with AJAX. I don't know where the Array list should be held in the first place (would it be in the web service or in the code behind? ), and how this can be done?

I'm putting together a way to cull out bad emails from my table.
I have an email field, of course, and a 'fail' field (integer)
Each time I send out an email, I get a bunch of emails back that the email addresses were undeliverable, so I'd like to (manually), enter them all into an array (or whatever), and then run a stored procedure which updates the 'fail' field by 1

I am trying to add row in DataTable CartDT using row[], which is a string array.
DataTable CartDT = new DataTable();
public void DataTableColumn()
{
CartDT.Columns.Add("Product_Name", typeof(string));
CartDT.Columns.Add("Product_ID", typeof(string));
CartDT.Columns.Add("ItemQTY", typeof(string));
CartDT.Columns.Add("Price", typeof(string));
CartDT.Columns.Add("TotalPrice", typeof(string));
[CODE]..
Now when I execute it, it gives the error that "Input array is longer than the number of columns in this table" The array row[] has exactly 5 elements in it & also DataTable CartDT has also 5 columns. Now i am not able to find exactly where i am wrong.

I am trying to implement the autocomplete method for textboxes.
I would like to use the example based on jquerys autocomplete provided here
<head>
<link href="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8/themes/base/jquery-ui.css" rel="stylesheet" type="text/css"/>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4/jquery.min.js"></script>
<script src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8/jquery-ui.min.js"></script>
<script>
$(document).ready(function() {
$("input#autocomplete").autocomplete({
source: ["c++", "java", "php", "coldfusion", "javascript", "asp", "ruby"]
});
});
</script>
</head>
The first and Main problem is that i do not know the way of passing my values to the source:
By saying that i mean, supposing i have a a server-side ASP.NET function GetTheResults as listof(string) or GetTheResults as string ()
how am i supposed to pass those values as source required by the auto-complete?
The second problem is that the specific way does not use AJAX.
Which means i guess on the load of the form i will load all the available values to the source. Isn't that an overkill?

How do you efficiently store and fetch data properties that is stored in an Array?
Public Function Customers() As IList
Dim cust = _dataNorthwind.Customers
Dim latt As New ArrayList()
For Each vlist In cust
latt.Add(vlist.CustomerId) 'how to store multiple properties here then fetch those?
[:(]
Next
Return latt.ToArray
End Function
I have a typical gridview/formview master control setup. When I try to update or insert I don't get any errors but it also doesn't work. When I try to insert data all I get are null values and when I update, none of the values are updated. The formview looks like its working, but just doesn't. The primary key is an identity and it auto-increments by one.

As what other member said in this community, the data assign a public variable may be shared among users, therefore, how am be able to declare a property that will accept an array of values using List<string>? The variable will be use in about fifteen pages...if I am going to declare this on each of the page, this will result to difficulty in maintaining the code of my program.
