DataSource Controls :: Resizing Two Dimensional Array - Filling Data In Loop
Mar 11, 2010
My original code was in classic vb. and could use redim array to resize them. I was porting the code to c# now and lately i have run into an issue to resize a 2 dimensional array. The thing here is I have a 2 dimensional array whose 2nd dimension needs to be increased dynamically as needed to accommodate the data. For say
String[,] ary1=new String[2,10];
I'm doing some operation in a loop and filling in the data in ary1. And if the loop still continues, on reaching the ary1 upper bound i need to increase the size further to accommodate 10 more rows. I tried couple of ways to copy it to a bigger array and assign it back to the current array. but somehow dint work.

First I am sorry if I am creating a thread in the wrong category as I am not sure which is the best suitable place for this question: I want to create a user defined data structure, which will be a 2 dimensional array such that each individual square of this 2-dimensional array will also store the score and the grades. ( Iam using VB.NET) More details: for example: There is an 2 dimensional array with 3 columns and 2 rows, I want to fill each of the (0,0);(0,1);(0,2) with their own score (Integer type) and grades (String Type). And this is same for the rest of the squares i.e. (1,0);(1,1);(1,2) and (2,0);(2,1);(2,2) After creating such custom data structure: "CustomArray", I should be able to create the instance of this custom data structure (which will be a class) and code something like this:
Dim objCustomArray as CustomArray
objCustomArray = New CustomArray
for i as Integer =0 to 3
objCustomArray(0,i).SetScore(1)
objCustomArray(0,i).SetGrade("Good")
Next
-------
for i as Integer =0 to 3
Dim myVal as Integer = objCustomArray(0,i).GetScore()
Dim myGrade as String = objCustomArray(0,i).gettGrade()
Next

Can we use a 2 dimensional array to bind it in our form? In my model I have this:
public class EmailDetails {
public string[] emailTo { get; set; }
public string[,] emailFieldValues { get; set; } }
So in my form to bind the emailTo is simple and this one works:
<input type="text" id="Text1" title=" " name="emailTo" maxlength="100" />
<input type="text" id="Text1" title=" " name="emailTo" maxlength="100" />
I need a 2 dimensional array so that I can match the value with something,
like this:<input type="text" id="Text1" title=" " name="EmailDetails["@name",valueofinput] maxlength="100" />

I have this array: string[,] productData = new string[5,7];
I bind it to a repeater and a call a method like: <img src="<%# getPhoto1WithReplace(Container.ItemIndex) %>"
Which is defined like:
public String getPhoto1WithReplace(Object itemIndex) {
int intItemIndex = Int32.Parse(itemIndex.ToString());
if (productData[intItemIndex, 3] != null) return this.ResolveUrl(productData[intItemIndex, 3].ToString());
else return String.Empty; }
I do not understand why it calls getPhoto1WithReplace with itemIndex as 5. My array has 5 indexes: 0,1,2,3,4, so How Container.ItemIndex can be 5?

I am getting an error when trying to serialize an object products.
Product product = new Product();
product.Name = "Apple";
product.Expiry = new DateTime(2008, 12, 28);
product.Price = 3.99M;
product.Sizes = new string[3,2] { {"Small","40"}, {"Medium","44"}, {"Large","50"} };
string json = JsonConvert.SerializeObject(product);//this line is throwing an error
Array was not a one-dimensional array. Is there any way to serialize a two dimensional array with Newtonsoft.json.

I've created an Excel spreadsheet for my users to upload into my web application to bulk import memberships and roles into the application. There are up to 4 different roles which users can be members of so I'm using AddUsersToRoles to add the user to one or more roles in one line of code like this:
r.AddUsersToRoles(usernames, CreateListOfRoles(Role1, Role2, Role3, Role4))
As this line of code expects a one-dimensional array of roles, I have created a function to take in the roles from my spreadsheet, add them into a one-dimensional array, and return that to the AddUsersToRoles method. The CreateListOfRoles function looks like this:
[Code]....
The error that I'm getting though is "System.InvalidCastException: At least one element in the source array could not be cast down to the destination array type." I've stepped through the Function in debug mode and all the values look correct and there are the correct number of items in the array so I don't understand what's going wrong.

I want to group by the date, these values are now in a dataset. What comes up to my mind is an array list with the following: The master array would have each date listed on the dataset above, within each row of this array I would have the list of numbers for that specific date. How do I do that in VB.NET?

How do you store multi-dimensional array to viewstate? Here's what I did:
public bool[,,] regsettings = new bool[7,5,4];
bool[,,] regsettings = (bool[,,])ViewState["regsettings"]; // this line works!
regsettings[i,j,tab] = (bool)ViewState["regsettings"]; // this line no working?! The error is: Object reference not set to an instance of an object. The letters i,j, tab are just variables in the loop. They are there. I also tried: (bool[,,,]) as a cast and it is a no-go either.?

I know I can use arrayName.length to find out how many items in total in the array there are, but how can I gracefully find out how many items are in a specific dimension? I know I could probably do it in a for each loop, but it would look a little messy, does anyone know of a simple way that I may have overlooked?

i have a table containing multiple agents , another three containing events ( three types of events , each category in a diffrernt table) organised by each agents! , i have to figure out how to fill a grid view that regroups a summary of the activity of every agent ! for example :
AGENT EVENT1 EVENT2 EVENT3
agent1 3 0 2 agent2 4 4 1
agent3 5 4 2
that means that the agent 1 have organised 3 EVENT1 0 EVENT2 and 2 EVENT3 ....
i have used the count(*) clause to fgure out the number of rows in table events referencing to each agent (group by) but it seems that value 0 is not returned by the clause , so i'm having a problem getting the exact values!
secondal , i have putted two calendar that will fix the beginnig and the end of the summary , but it seems that the end day is not included : it says 18/01/2010 00:00:00 and i have some events planned in 18/10/2010 14:10:00 so they are not counted !

I have an array that I need to display using a feature like listview. Is that possible? I need to be able to display a "temporary" list of information that the user may add or delete entries. Once they approve the list I will loop through the list and store the information in a table.

I need to build an array of implicit objects in a var object by looping through a List and adding the to the array. For example...
Code:
var data = new[] { new { Name = "China", Value = 1336718015 },
new { Name = "India", Value = 1189172906 },
new { Name = "United States", Value = 313232044 },
new { Name = "Indonesia", Value = 245613043 },
new { Name = "Brazil", Value = 203429773 },};
If I wanted to dynamically add new objects with the Name and Value values above by a looping through an existing List, how would I go about it?

I've got a while loop that's doing some stuff, and what I want is for it to create a new array each time.
while(condition){
//do some stuff
//create an array x[]
//amend values in array
//save as new array each time until loop finished
}
Actually i need to store the comma separated values of different datatypes in an array using split.And then i hav to sort these values comparing zeroth position element of all rows.

I have to set GridView.DataKeyNames(This is really a question about the syntax for a string array, in VB.Net.)
I am discovering the PrimaryKey columns names from within a loop, ie:
For Each fld As IEntityField In Me.llbDataSource.EntityCollection(0).PrimaryKeyFields 'fld.Name ' this is where the column name is stored, so I have to get this into an array Next I can not use this syntax.
GridView.DataKeyNames = new string() { "PowRatHP", "Voltage", "Phases", "Poles", "Drive" }
So, basically, how does one declare a string array (as required by GridView.DataKeyNames), and then populate the elements of the array from within a loop?
