The problem is: How should I do this? I've search several hours on the internet but can't find anything about how to split strings from a datareader to several different arrays.
I have a 2D array and i want to search that array. I thought Array.Find might help but it was helping only in 1D. I dont want to use for loop or foreach as that will take some time. So is there any other shortest method to find a value in a 2D array.
I have a datareader that i loop through comparing the values of the reader to the ones i got in an (from the start, empty) array, as i do this i want to put either a new post in the array or update an existing post depending on if i found a corresponding value or not. The datareader and array both contains name and value.
First i tried to declare a regular multidimensional array, but they are fixed size so that seemed like a bad idea, next thing i tried was creating an arraylist but they seemed to lack support for multidimension. I'm a bit lost on what to use.
So, I've got an array, filled with data from dynamic input fields. the input fields are PIN, Name and Description... and the user can add as many "sets" of these three fields as they want.
This data goes into an array.
For example, the array may have 11111, Test Name, Test Company 22222, Second Name, Second Company
etc. etc.
I know I can see the values of my array, so if I were to take: item(0) & ", " & item(1) & ", " & item(2)
my output would be: 11111, Test Name, Test Company
The problem I'm having, is, I need to write ALL of the groupings of three out to a file... and I'm stuck on how to do that. So, I need a way to loop through until the end of the array and get:
I now have two asp.net pages. When I click on a link on page A, I open the other one (let's call it page B). When I do this, I want to send some information from Page A to Page B in the form of an array of strings. This array is different depending on what link I follow on Page A.
I know I could send this information via the URL with the ?string1=bla1&string2=bla2 etc., but I don't want it that way, as it can get complicated if there are too many strings in the array.
I think there is something similar, like a POST in PHP, but how would that be in ASP?
I want to read all the strings from a resx file and load it into an array without looping. I'm working in an asp.net web application and i'm using C#. How can i get the strings?
What I have is a table that holds 3 input elements, They represent order, name, value. The user can add a new row of 3 inputs to add as many of these sets of data as they want.
To accomplish the dynamically adding in of inputs I use jquery's clone method. That works fine and I am able to iterate through each and grab the values, however the real pain I am having is that when the user has entered in all of the data I want to pass that data to an asp.net page through jQuery's post method. How do I go about passing an array of strings so that I send this format to the asp.net page, and when I've done that how do i parse the data on the asp.net side of it.
Desired Data Format:
["Name|Link|Order", "Name|Link|Order", "Name|Link|Order"] jquery Code so far: $("#saveBtn").click(function (e) { e.preventDefault(); $("#addPanel").slideUp(300); //Perform Save Operation var saveString = ""; $("#addTable tbody>tr").each(function () { var o = $(this).find(".hsaorder").val(); var n = $(this).find(".hsaname").val(); var l = $(this).find(".hsalink").val(); saveString += n + "|" + l + "|" + o ; }); ////// Create Array here or some other method? $.post("/modules/H/Modify.aspx", { OBVIOUSLY SOMETHING GOES HERE}); // Remove all but top table element to return to original state $("#addTable tbody>tr").not("#addTable tbody>tr:first").remove(); });
I'm having a method that exports content from the database to excel files. The method taks as paramaters a DataReader param and a int param - the number of rows. For the number of rows i'm using a dataset, wich i fill using the same query as for the datareader. So I'm executing it twice... Is there a way I can avoid that? get the number of rows from the datareader?
I am getting an error that an open DataReader associated with this Command, when I'm not using datareader(though probably executereader() is the same thing) how would I close this if I don't have a datareader present?
using (SqlConnection conn = new SqlConnection(ConnectionString)) { SqlCommand cmd = new SqlCommand("spSelectAllTypes",conn); cmd.CommandType = CommandType.StoredProcedure; [code]...
I just want to be able to databind a bunch of dropdownlist in one open connection. (before I had multiple open and closes for each control)
I 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.
Iam getting an array of list from database to client side(javascript array). Now my aim to place those values in a div one by one and that div should attach to the textbox similar to Autocomplete extender.
I need to store some values in a collection and am wondering what the best way to do it would be.Here's what i've got going on:
[Code]....
I was thinking something like this: object[,,,] = new object[productID, productName, productPrice]But I really don't think that's the best way to do this. Does anyone know the best practice for this?
I'm very new to the whole thing and am slowly building a little app which takes a series of numbers into an array,orders them,does calculations and outputs the result.To this end I'm using arrays declared like:
string[] and the function OrderBy().
Eventually this little prog is intended to read text files containing perhaps thousands of values so I thought I should find out:
What are the size limits for such arrays?What are the size limits for OrderBy() ? Is OrderBy() an effective sort routine for large arrays or does it get very slow? I hope it is okay to ask these questions.I realise I could find out for myself as soon as I've got it to where it can upload and read a text file and process it...... but I'm not there yet.
I'm taking input from a user and need to stick it into an array, the problem is, I don't know ahead of time how many dimensions the array will have and I also don't know how many items the user will want to stick in each dimension.The array will have a maximum number of dimensions of 4, but an unlimited number of items per dimension.I'm trying to create an unordered html list creator, so I need to know the number of items in each level of the list, and since (As far as I know) you can't create a multi dimensional array with a dynamic size
I have several models that implement a array property using null object pattern in the following manner:
[Code]....
The problem is that any time I attempt to bind to a property of this type the DefaultModelBinder.CollectionHelpers.ReplaceCollectionImpl method wants to call ICollection<T>.Clear() and then ICollection<T>.Add() on the zero length array.
The real issue seems to be in DefaultModelBinder.BindComplexModel() method however. The method contains an explicit check for arrays and special handling to account for the fact that they don't support clear/add functionality. The problem is that the check stipulates that the array model must also be null. If it is non-null, normal ICollection<T> handling ensues which presumes support for clear and add. Can any one explain why the null check is there? It seems to me that either 1) the null check should be removed to permit replacement based binding to non-null arrays or 2) an explicit error stating that non-null arrays are not supported should be thrown.
I vote for the former. I can understand that in general, replacing an existing model with a refrence to a different model would be considered a bad thing. The calling code would not expect this in general and it could lead to hard to find bugs. However, in the case of arrays, if the calling code expects the array property to be modified at all, then I think the normal expectation would be that such modification would occur via replacement of the array.
