Web Forms :: Passing Data Between 2 Web Applications?
Jan 31, 2011
I would like to implement the following functionality between 2 web applications:
a) Web application one contains a button, which, when pressed launches another web application.
b) The second application contains a form that is filled in by the customer.
c) After filling in the form, the second application validates the information and returns a 5 digit code to indicate whether validation was successful.
d) Web application one then displays the status and asks the user to continue with other steps.
Is the above scenario possible? Is it possible to transfer data between 2 seperate web applications? I have considered using a query string, database and flat file to trasnfer the data from one application to another. Which of these (if any) would be the best choice?
I need to design two apps who can interact with each other. The first app, App A needs to send an encrypted string over to App B and App B will have to decrypt it and do some stuff. How would I go about that?
App A - http://MachineA/default.aspx App B - http://MachineB/default.aspx
I tried encrypting the data using AESCryptoServiceProvider and it returns a byte[]. Now how would I transfer it over to another application? Via query strings?
We have several web applications that create a shopping cart, save it to a database, then redirect to a centralized web application to process and accept payment for the shopping cart. Right now, we are using GUIDs for the shopping cart IDs and passing those GUIDs in the querystring to the payment application. We are using GUIDs so that a user cannot easily guess the shopping cart ID of another user and simply plug that ID into the URL.
Now, using GUIDs in the database is bad for indexing and using GUIDs in the URL does not truly prevent a user from accessing another cart. However, using passing integers around would make it too easy.
What is the best and most secure way to pass the IDs from the individual applications to the centralized payment application?
I know that some people may say, "Who cares if someone else wants to pay for someone else's shopping cart?" However, we have the same concern when passing IDs to the page that displays the receipt and that page includes the customer's name.
I had three web applications and each one has its own login page , now i want to build web portal which allow members to login and choose one of these applications to redirect to it .
Is there any way to passing user information across secure connection??
I've been worked with web services so far, and I'm interested in expanding my services to console applications as well so I started digging up with WCF but I'm conserned that I won't be able to use the HttpContext collection that I've been used to do with web services one important thing which is to generate a random value from HttpContext.Current.Request.ServerVariables["ALL_HTTP"] that I need to reckon if it's the same or at least near what machine that is calling my service. How can I overcome this problem?
I need to know what machine is calling to count the number of attempts to login into my system for example. So must do it inside of the svc code otherwise if I let the client inform what ip address or what computer he is using, anyone could forge this argument and surpass by another machine. May be I'm approaching this matter wrongly. And I should count the number of attempts per state session, but how is it done?
im about to wirte an app that is an extension from the main application that is hosted on the IIS. My application is going to work as a child app (main app as parent) working in main application pool. User will be redirected from the menu to main app to my website. And here is my problem. I would like to pass informations like user login, login state etc. I cant do it via Query String - that wouldnt be safe. I thought I could pass it via Session state, since the SessionID is the same both sides but I cannot retrives parameters on my website(theyre null).
Our corporate intranet is designed so that each web application is a child application in the primary application.. Everything has worked fine with Visual Studio 2008 and even in 2010 running the website locally works great, the output directory for the child apps is ..in and the ProjectName.dll copies to that directory.. When I do a publish however it does not and I have to manually copy the dll from the bin folder in the project folder to the parent bin folder, this isn't hard of course but more of a pain in the butt each time I need to publish something. I made sure the output directory is correct for both debug and release yet on publish is just copies it to the child bin and not the parent bin as needed.
Long story short: I'm basically trying to learn visual web developer/asp.net/and how to get all this to work on a shared hosting environment. The idea is to eventually develop this into something a friend of mine with a garage can use to allow his customers to check their various maintenance records. I basically made a small database with a couple of test tables in it and a gridview to display data based on a variable passed from a text box. I finally got it working on my shared hosting server with just one such 'application', but when I tried to add a second one, both stop working. If I put one in default.aspx, and the other in default1.aspx, they both work perfectly. I've tried using the same dataset for both, and different datasets for each, and same behavior. Also tried using 1 and 2 objectdatasources with the same results. Also tried putting each in their own content placeholders and no change. From my research into the subject, I've come to the conclusion that more than one gridview isn't the problem, so I'm extra stumped now. I'm guessing it's something relatively simple for someone who knows this stuff. Oh, I thought it may have something to do with not using default values, so the 'tables' weren't being drawn, so there wasn't 'room' to do so, but after splitting the apps into two different divs, and floating one bottom/right, again, no change.[URL](first working example)[URL](second working example)[URL](both in same page, not working - might not be up yet if someone reads this quickly)
I have a web application (MainApplication) where many of the pages contain a custom Web Control that looks for some content in a cache. If it can't find any data within the cache, then it goes out to a database for the content. After retrieving the content, the Control displays the content on the page.
There is a web application (CMS) in a subdirectory within the aforementioned web application. Users use this CMS to update the content pulled in by the MainApplication.
When a user updates some content using the CMS, I need the CMS to clear the relevant portion of the cache used by the MainApplication. The problem is that, as two different web applications, they can't simply interact with the same static cache object.
The ideal solution would be to somehow share an instance of a cache object between both web applications.
Failing that, what would be the best (performance-wise) way of communicating between the two web applications? Obviously, writing/reading to a database would defeat the purpose. I was thinking about a flat file?
I have a ListView displaying data from Table A using a SqlDataSource.
I want to take the displayed data (and these are just the standard columns representing fields in Table A) and store them in Table B using a Stored Procedure
(The scenario is much more complex but I've left out anything not relating to this exact problem).
I've added a Button to the ListViews ItemTemplate and I'm using OnItemCommand to create a Sub for its "Click" in the Code Behind.
This is a simplified chunk of the SQL I'm using to insert the ListView's fields into Table B using the Stored Procedure "InsertCart":
[Code]....
Where I've highlighted "Description" in the last line. In a GridView, this would be enough. Description is a Column name in Table A and B and iy's an Item in the ListView. But I'm realising that, with ListView's, the data binding is not as "automatic" as a GridView. Just using the columnname is not enough.
What do I use instead of the word Description to reference this column in the Parameter?
I have a gridview and I have an edit template for one control. I have a drop down box in this edit template so that you can select a value from it and then when you hit 'Update' the value from the drop down box is committed to the updated record. Unfortunately when I do hit the update button I get a fault that the "Status" field cannot be null.
Here is the code that picks the value from the drop down value and assigns it to the new values list:
I need to be able to evaluate the text value of the template button or pass date from the dbDateOpened colum when the button is pressed. Either direct I have tried gives me an compile error. With the current configuration I get this error. "Object reference not set to an instance of an object."
I'm using the DetailView control to display employee details from a specfic company, but it seems when I try to create the query in the data source wizard I'm unable to select the variable for the WHERE clause, only the web pages control components.
The employees are selected through the company name which is entered at the beginning of the page and in turn is used to select the company id.
In my asp.net web page i have a dropdown box. Say like i have to bind EmployeeName to this dropdown box to show up as items.
I am using a dataTable to bind to this grid by having two columns in DataTable (EmployeeId and EmployeeName). But i am only binding the EmployeeName to the dropdown list box.
In the UI, after the user selects an Employee, I need to pass that employee's id to a function. Is there any way, i can directly pass the underlying data (EmployeeID in the DataTable attached to this dropdown), when the user selects the EmployeeName from the dropdown. Or i will have to make a roundtrip to the database and get the selected Employee's Id and then pass it to the function.
I have some doubt about GridView PageSize, for the example if my table have more than 100000 rows and i set PageSize=50, i can see GridView trying to download whole 100000 rows and display only 50 records with pagewise.
In this case my application getting very slow.
Is there anyway to force GridView download data according to the pagesiz without passing limit in sql?

I have two tables: Book and author and they have one to many relation.One book may have more than one authors. Book table has Title column and Author table has AuthorName Column.
I have search page contains two textboxes: Title Textbox and AuthorName textbox to search the record.
When the user type something and hit the search button it display the Title when click the title ; it redirect to detailsPage.aspx Passing value ID.
[Code]....
Then in the Details page there are: Title, authors and other more from these table column.
My problem is:
When the user search and hit the search button, it display the number of matches Title only. I want to display authors related to this title in this page and other are same(when click the title go to detailspage.aspx)
How can I display the related Authors to each title in search display page (Not in details page, I know in details page) ?
If user search "The Letters and life" in the Title textbox and hit enter data should looks like:
1. Author: Payne Paddy, sed ran, der virma and Caroline Barron.
Title: The Letters and Life of Elizabeth Despenser, Lady Zouche (d. 1408) [her letters and will provide a glimpse of her personal
I have a page where there are two nested gridview, I have a column in the child gridview that uses a function to display the data.This function uses the id of the id of the father and son as parameters. I tried the code below, but does not work ...
I have a DetailsView that I am trying to use to pass results to an applet's parameter list but I can't figure it out.
Example:
<asp:DetailsView ID="...".... <Fields> <asp:boundfield Datafield="Name".../> <asp:boundfield Datafield="Name2".../> ...etc. <applet codebase="http:/..." ...> param name="Name" value="value of Name from my DetailsView" /> param name="Name2" value="value of Name2 from my DetailsView" /> ...etc.
I have been trying all sorts of things and viewing tutorials, etc, but I just don't seem to be able to figure this out.
Is there any way to pass a List<T> that's generated during the page load process to a Javascript function that's called when the user presses a button without having to manually serialize/deserialize the data every time (such as is the case with XML/JSON cookies)?
