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?

Web Forms :: Passing Encrypted Data Between Two Applications

Jan 25, 2011

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?

http://MachineB/default.aspx?data=<<EncryptedString>>

Query strings does not take a byte[] parameter. So I am clueless now.

Passing IDs Between Web Applications?

Jul 14, 2010

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.

WCF / ASMX :: Building Services To Work With Web Applications And Console Applications?

Jun 7, 2010

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.

Configuration :: Deploying Web Applications With Sub Web Applications?

Apr 22, 2010

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.

Forms Data Controls :: Gridview Applications Work Fine On Different Pages

Apr 1, 2010

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)

Sharing Data Between Two Web Applications?

Oct 14, 2010

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?

Forms Data Controls :: Syntax For Passing ListView Data To SQL Input Parameters?

Dec 11, 2010

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?

Forms Data Controls :: Gridview Not Passing Parameters To SQL Data Source?

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:

Forms Data Controls :: Passing The Underlying Data Of The Databound Control?

Mar 30, 2010

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.
