  • Using POST or SESSION to capture data

    - by Karinne
    Hi all! I'm currently working on web application using VB in ASP.NET. Right now I have 1 page with panels that we are using to show/hide depending on the flow. When the user first comes in, he/she is presented with a gridview containing a list of clients. Then the user, clicks a link from a row and is presented a form where he/she can update the clients' info. Originally, I had a HYPERLINKFIELD that put the clientId in the url, then I'd grab the url and do the code appropriately <asp:HyperLinkField Text='<%$ Resources:Resource, ManageClient %>' DataNavigateUrlFields="CLIENT_ID" DataNavigateUrlFormatString="~/clients/manage.aspx?clientId={0}" /> Now, I'm rethinking that and wondering if it's better to use SESSIONs to grab the clientID via this instead <asp:TemplateField Visible="false"><ItemTemplate><asp:Label runat="server" ID="hidClientId" Text='<%# Bind("CLIENT_ID")%>' Visible="false" /></ItemTemplate></asp:TemplateField> <asp:ButtonField Text='<%$ Resources:Resource, ManageClient %>' CommandName="Manage" /> Or use the POST method, which I'm not sure how it works in .NET (but I've used it in PHP) Any help would be greatly appreciated.

  • Program structure in long running data processing python script

    - by fmark
    For my current job I am writing some long-running (think hours to days) scripts that do CPU intensive data-processing. The program flow is very simple - it proceeds into the main loop, completes the main loop, saves output and terminates: The basic structure of my programs tends to be like so: <import statements> <constant declarations> <misc function declarations> def main(): for blah in blahs(): <lots of local variables> <lots of tightly coupled computation> for something in somethings(): <lots more local variables> <lots more computation> <etc., etc.> <save results> if __name__ == "__main__": main() This gets unmanageable quickly, so I want to refactor it into something more manageable. I want to make this more maintainable, without sacrificing execution speed. Each chuck of code relies on a large number of variables however, so refactoring parts of the computation out to functions would make parameters list grow out of hand very quickly. Should I put this sort of code into a python class, and change the local variables into class variables? It doesn't make a great deal of sense tp me conceptually to turn the program into a class, as the class would never be reused, and only one instance would ever be created per instance. What is the best practice structure for this kind of program? I am using python but the question is relatively language-agnostic, assuming a modern object-oriented language features.

  • I have created a PHP script and I am lacking to extract the primary key, I have given flow below, pl

    - by Parth
    I am using MySQL DB, working for Joomla, My requirement is tracking the activity like insert/update/delete on any table and store it in another audit table using triggers, i.e. I am doing Auditing. DB's table structure: Few tables dont have any PK nor auto increment key Flow of my script is : I fetch out all table from DB. I check whether the table have any trigger or not. If yes then it moves to check nfor next table and so on. If it does'nt find any trigger then it creates the triggers for the table, such that, -it first checks if the table has any primary key or not(for inserting in Tracking audit table for every change made) if it has the primary key then it uses it further in creation of trigger. if it doesnt find any PK then it proceeds further in creating the trigger without inserting any id in audit table Now here, My problem is I need the PK every time so that I can record the id of any particular table in which the insert/update/delete is performed, so that further i can use this audit track table to replicate in production DB.. Now as I haave mentioned earlier that I am not available with PK/auto-incremented in some table, then what should I do get the particular id in which change is done? please guide me...GEEKS!!!

  • IndexOutOfRangeException when a stream is a multiple of the buffer size

    - by dnord
    I don't have a lot of experience with streams and buffers, but I'm having to do it for a project, and I'm stuck on an exception being thrown when the stream I'm reading is a multiple of the buffer size I've chosen. Let me show you: My code starts by reading bufferSize (100, let's say) bytes from the stream: numberOfBytesRead = DataReader.GetBytes(0, index, output, 0, bufferSize); Then, I loop through a while loop: while (numberOfBytesRead == bufferSize) { BufferWriter.Write(output); BufferWriter.Flush(); index += bufferSize; numberOfBytesRead = DataReader.GetBytes(0, index, output, 0, bufferSize); } ... and, once we get to a non-bufferSize read, we know we've hit the end of the stream and can move on. But if the bufferSize is 100, and the stream is 200, we'll read positions 0-99, 100-199, and then the attempt to read 200-299 errors out. I'd like it if it returned 0, but it throws an error. What I'm doing to handle that is, well, a try-catch: catch (System.IndexOutOfRangeException) numberOfBytesRead = 0; ...which ends the loop, and successfully finishes the thing, but we all know I don't want to control code flow with error handling. Is there a better (more standard?) way to handle stream reading when the stream length is unknown? This seems like a small wrinkle in a fairly reasonable strategy for reading streams, but I just don't know if I've got it wrong or what. The specifics of this (which I've cleaned up a little bit for posting) are a MySqlDataReader hitting a LARGEBLOB column. It's working whenever the buffer is larger than the number of returned bytes, or when the number of returned bytes is not a multiple of bufferSize. Because we don't, in that case, throw an IndexOutOfRangeException.

  • Multi-Part HTTP Request through xcode

    - by devsri
    Hello Everyone, i want to upload image,video and audio files to a server. I have read this thread on the similar topic but wasn't able to understand completely the flow of the code. It would be great if you can suggest me some sample code or tutorial to start with. I am using the following code to connect without any media to the server [UIApplication sharedApplication].networkActivityIndicatorVisible = YES; NSString *url =[[NSString alloc]initWithFormat:@"%@",[NetworkConstants getURL]]; NSURL *theURL =[NSURL URLWithString:url]; [url release]; NSMutableURLRequest *theRequest =[NSMutableURLRequest requestWithURL:theURL cachePolicy:NSURLRequestReloadIgnoringCacheData timeoutInterval:0.0f]; [theRequest setHTTPMethod:@"POST"]; NSString *theBodyString = [NSString stringWithFormat:@"json1=%@&userID=%@",jsonObject,[GlobalConstants getUID]]; NSData *theBodyData = [theBodyString dataUsingEncoding:NSUTF8StringEncoding]; [theRequest setHTTPBody:theBodyData]; NSURLConnection *conn = [[NSURLConnection alloc] initWithRequest:theRequest delegate:self]; if (conn) { NSLog(@"Successful in sending sync"); } else { NSLog(@"Failed Connection in sending sync"); } [conn release]; It would be really convenient for me if anything could be done editing this part of code. Any form of help would be highly appreciated. Thanks in advance!!

  • How to control the "flow" of an ASP.NET MVC (3.0) web app that relies on Facebook membership, with Facebook C# SDK?

    - by Chad
    I want to totally remove the standard ASP.NET membership system and use Facebook only for my web app's membership. Note, this is not a Facebook canvas app question. Typically, in an ASP.NET app you have some key properties & methods to control the "flow" of an app. Notably: Request.IsAuthenticated, [Authorize] (in MVC apps), Membership.GetUser() and Roles.IsUserInRole(), among others. It looks like [FacebookAuthorize] is equivalent to [Authorize]. Also, there's some standard work I do across all controllers in my site. So I built a BaseController that overrides OnActionExecuting(FilterContext). Typically, I populate ViewData with the user's profile within this action. Would performance suffer if I made a call to fbApp.Get("me") in this action? I use the Facebook Javascript SDK to do registration, which is nice and easy. But that's all client-side, and I'm having a hard time wrapping my mind around when to use client-side facebook calls versus server-side. There will be a point when I need to grab the user's facebook uid and store it in a "profile" table along with a few other bits of data. That would probably be best handled on the return url from the registration plugin... correct? On a side note, what data is returned from fbApp.Get("me")?

  • jqGrid using a servlet to store the data, how to access the data from a different java class

    - by Sam
    I'm using jqGrid for a table input and setting up the url as a servlet which will deal with the GET and POST requests and save the rows to a Java object. I'm using webwork web framework and I was wondering how I can get access to the object that the servlet is saving the data to. One way I have thought of is to just call the GET method from the Java action class which the servlet will return a JSON string with the object data. Is there a better design for doing this? This is probably not too clear so ask questions so I can help get across my point. Thanks

  • Putting data from local SQL database to remote SQL database without remote SQL access enabled (PHP)

    - by Shyam
    Hi, I have a local database, and all the tables are defined. Eventually I need to publish my data remotely, which I can do easily with PHPmyadmin. Problem however is that my remote host doesn't allow remote SQL connections at all, so writing a script that does a mysqldump and run it through a client (which would've been ideal) won't help me here. Since the schema won't change, but the data will, I need some kind of PHP client that works "reverse". My question is if such a client exists and what would be recommended to use (by experience). I just need an one way trip here, from my local database (Rails) to the remote database (supports PHP), preferable as simple and slick as possible. Thank you for your replies, comments and feedback!

  • Updating a progress bar while wpf data binding is taking place (in c#)

    - by evan
    I bind a large dataset to a WPF list box which can take a long time (more than ten seconds). While the the data is being bound I'd like to display a circular progress bar I can't get the progress bar to show while the data binding is occurring, even though I am trying to do the binding in a backgroundworker. I tested it by making the first line of the backgroundworkd's dowork event a Thread.Sleep(5000) and sure enough the progress bar started spinning for that duration only to freeze while when the binding started. Is this because both the databinding and the UI updating have to occur on the same thread? Any ideas on how to work around it? Thanks for your help!!

  • How to update data in the user information list when using FBA

    - by Flo
    I've got to support a SharePoint web application which uses FBA with a custom membership and a custom role provider to authenticate the user against two different LDAPs. The user data are only stored in the user information lists. The SSP user profiles are not used. Now one of the users got married and therefore her surname got changed in the LDAP (the one where her information are stored). But this change doesn't get provisioned into the user information list. I wondering what option I have to provision changes of user data to the user information list. I've already tried to update the last name of the user manually, but it seems as if certain information like surname, first name are not editable in the user information list. I tried to edit them as a site administrator. So what option do I have to solve this problem? Being able to edit the information per hand would also be a solution but of course not the most preferred one.

  • jqGrid adding new row with XML Data

    - by mahr.g.mohyuddin
    Hi Everyone, I am using jQGrid in my ASP.NET MVC application with add row feature. My problem is I have to save XML data in some of the row fields. But while posting the new row with some fields having plain xml, to server I get Internal server error. By default jqGrid perhaps expects json or text data to be posted on server while adding a new row. I used beforeSubmit method for workaround to convert xml first to json and then send to server, but while converting json back to xml I lose the orginal structure of the xml. FYI: I used JsonReaderWriterFactory on server to convert it back. Your help will be highly appreciated. Thanks.

  • Importing Excel to SQLCE

    - by ohadsc
    I have a table in excel format (2007 but I can save as anything below that, naturally), and I have an SQL Compact Edition 3.5 SP1 Database table with corresponding columns. I simply want to populate the SQLCE table with the data from the excel file. The data consists of strings and integers only. I tried this utility to no avail, I also tried this SQL script but it won't work since BULK INSERT is not supported in SQLCE. I also found this Microsoft tutorial but I am basically clueless when it comes to SQL, providers and the like... Thanks !

  • ASP.NET MVC2: Getting textbox data from a view to a controller

    - by mr_plumley
    Hi, I'm having difficulty getting data from a textbox into a Controller. I've read about a few ways to accomplish this in Sanderson's book, Pro ASP.NET MVC Framework, but haven't had any success. Also, I've ran across a few similiar questions online, but haven't had any success there either. Seems like I'm missing something rather fundamental. Currently, I'm trying to use the action method parameters approach. Can someone point out where I'm going wrong or provide a simple example? Thanks in advance! Using Visual Studio 2008, ASP.NET MVC2 and C#: What I would like to do is take the data entered in the "Investigator" textbox and use it to filter investigators in the controller. I plan on doing this in the List method (which is already functional), however, I'm using the SearchResults method for debugging. Here's the textbox code from my view, SearchDetails: <h2>Search Details</h2> <% using (Html.BeginForm()) { %> <fieldset> <%= Html.ValidationSummary() %> <h4>Investigator</h4> <p> <%=Html.TextBox("Investigator")%> <%= Html.ActionLink("Search", "SearchResults")%> </p> </fieldset> <% } %> Here is the code from my controller, InvestigatorsController: private IInvestigatorsRepository investigatorsRepository; public InvestigatorsController(IInvestigatorsRepository investigatorsRepository) { //IoC: this.investigatorsRepository = investigatorsRepository; } public ActionResult List() { return View(investigatorsRepository.Investigators.ToList()); } public ActionResult SearchDetails() { return View(); } public ActionResult SearchResults(SearchCriteria search) { string test = search.Investigator; return View(); } I have an Investigator class: [Table(Name = "INVESTIGATOR")] public class Investigator { [Column(IsPrimaryKey = true, IsDbGenerated = false, AutoSync=AutoSync.OnInsert)] public string INVESTID { get; set; } [Column] public string INVEST_FNAME { get; set; } [Column] public string INVEST_MNAME { get; set; } [Column] public string INVEST_LNAME { get; set; } } and created a SearchCriteria class to see if I could get MVC to push the search criteria data to it and grab it in the controller: public class SearchCriteria { public string Investigator { get; set; } } } I'm not sure if project layout has anything to do with this either, but I'm using the 3 project approach suggested by Sanderson: DomainModel, Tests, and WebUI. The Investigator and SearcCriteria classes are in the DomainModel project and the other items mentioned here are in the WebUI project. Thanks again for any hints, tips, or simple examples! Mike

We are up to doing some analysis like “what town had its first population gain in 10 years?” etc.My question is just about can we do this in Excel,or do we need to export the data to other database(SQL) then do the programming?

  • Extracting, then passing raw data into another class - How to avoid copying twice while maintaining

    - by Kache4
    Consider a class Book with a stl container of class Page. each Page holds a screenshot, like page10.jpg in raw vector<char> form. A Book is opened with a path to a zip, rar, or directory containing these screenshots, and uses respective methods of extracting the raw data, like ifstream inFile.read(buffer, size);, or unzReadCurrentFile(zipFile, buffer, size). It then calls the Page(const char* stream, int filesize) constructor. Right now, it's clear that the raw data is being copied twice. Once to extract to Book's local buffer and a second time in the Page ctor to the Page::vector<char>. Is there a way to maintain encapsulation while getting rid of the middleman buffer?

    Hi, Can you help me in the following two scenarios (PHP+MYSQL) Scenario1: I need to compare the HTML Form field values with the Database field values and highlight the form fields in some color whose values are different from database values before submitting the form (to alert the user). Scenario2: On loading the form, i need to compare the values present in 2 different database tables (tables are having different column names but the information is same). the fields which are not same needs to be highlighted in the html form to indicate the users that the master data is varying from secondary data. Could you help me which is the efficient way of doing this (comparison and highlighting the form values). thanks in advance Naveen

  • PopulateOnDemand does not work on data bound ASP.Net TreeView

    - by Shay Friedman
    Hi, I have a TreeView that is bound to a XmlDataSource control. I've added some TreeNodeBinding elements to define how I want the XML data to be shown. I have also added PopulateOnDemand=true to these TreeNodeBindings. However, doing so didn't change a thing and the entire XML tree is displayed. Moreover, the TreeNodePopulate event is not fired on node expand as well. Important information: I'm using ASP.NET 4. This is an example that reproduces the problem (very straight forward): <%@ Page Language="C#" AutoEventWireup="true" %> <script type="text/C#" runat="server"> protected void TreeView1_TreeNodePopulate(Object sender, TreeNodeEventArgs e) { // This method is never called... } </script> <html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <title></title> </head> <body> <form id="form1" runat="server"> <div> <asp:TreeView ID="TreeView1" runat="server" DataSourceID="XmlDataSource1" OnTreeNodePopulate="TreeView1_TreeNodePopulate" ExpandDepth="0"> <DataBindings> <asp:TreeNodeBinding DataMember="#" TextField="#" ValueField="#" PopulateOnDemand="true" /> </DataBindings> </asp:TreeView> <asp:XmlDataSource ID="XmlDataSource1" runat="server" DataFile="Sample.xml" /> </div> </form> </body> </html> The Sample.xml can be any xml file you want, it doesn't really matter. I tried to put a breakpoint within the TreeView1_TreeNodePopulate method and it was never hit. I also tried to: Set a TreeNodeBinding for each possible data member with PopulateOnDemand="true". Via code, go through all tree nodes and set their PopulateOnDemand property to true. Nothing worked. The only way the populate-on-demand thing worked was when I added nodes manually to the nodes instead of binding it to a data source. What am I doing wrong?

  • Metalanguage like BNF or XML-Schema to validate a tree-instance against a tree-model

    - by Stefan
    Hi! I'm implementing a new machine learning algorithm in Java that extracts a prototype datastructure from a set of structured datasets (tree-structure). As im developing a generic library for that purpose, i kept my design independent from concrete data-representations like XML. My problem now is that I need a way to define a data model, which is basically a ruleset describing valid trees, against which a set of trees is being matched. I thought of using BNF or a similar dialect. Basically I need a way to iterate through the space of all valid TreeNodes defined by the ModelTree (Like a search through the search space for algorithms like A*) so that i can compare my set of concrete trees with the model. I know that I'll have to deal with infinite spaces there but first things first. I know, it's rather tricky (and my sentences are pretty bumpy) but I would appreciate any clues. Thanks in advance, Stefan

  • Python (Twisted) - reading from fifo and sending read data to multiple protocols

    - by SpankMe
    Hi, Im trying to write some kind of multi protocol bot (jabber/irc) that would read messages from fifo file (one liners mostly) and then send them to irc channel and jabber contacts. So far, I managed to create two factories to connect to jabber and irc, and they seem to be working. However, I've problem with reading the fifo file - I have no idea how to read it in a loop (open file, read line, close file, jump to open file and so on) outside of reactor loop to get the data I need to send, and then get that data to reactor loop for sending in both protocols. I've been looking for information on how to do it in best way, but Im totally lost in the dark. Any suggestion/help would be highly appreciated. Thanks in advance!

  • [cocoa] NSSearchField not working as expected

    - by Vegar
    Hi, I'm trying to follow Marcus Zarra in his book 'Core Data'. In the book, he makes a small sample application, but it doesn't give much help when things don't work out... He starts out by visually designing three entities, and then adding array controllers for each entity to the main nib. Second, he adds a tableview and some other visual components to show data from the array controllers. So far, I have managed to follow, but now he adds a search field to the gui, and binds it to the same array controller as one of the tableviews. Expected behavior would be for the tableview to get filtered when typing in the search field, but nothing happens. How do I find out what's wrong? The relevant parts from the nib is as follow: NSArrayController Recipes - Mode = Entity - Enitity Name = Recipe TableView w/TableColumn - Value Bind To Recipes -- Controller Key = arrangedObjects -- Model Key Path = name Search Field - Predicate Bind To Recipes -- Controller Key = filterPredicate -- Model Key Path = name -- Display name = predicate -- Predicate Format = keyPath contains $value There are no relevant messages in the console. regards, -Vegar

  • Core Data performance deleteObject and save managed object context

    - by Gary
    I am trying to figure out the best way to bulk delete objects inside of my Core Data database. I have some objects with a parent/child relationship. At times I need to "refresh" the parent object by clearing out all of the existing children objects and adding new ones to Core Data. The 'delete all' portion of this operation is where I am running into trouble. I accomplish this by looping through the children and calling deleteObject for each one. I have noticed that after the NSManagedObjectContext:Save call following all of the deleteObject calls is very slow when I am deleting 15,000 objects. How can I speed up this call? Are there things happening during the save operation that I can be aware of and avoid by setting parameters different or setting up my model another way? I've noticed that memory spikes during this operation as well. I really just want to "delete * from". Thanks.
