Web Forms :: Want To Qualify My Users Ability To Use Javascript?
Jun 8, 2010
I want to qualify my users ability to use javascript when they enter my website so I can manage any depreciated functionality properly.
I found some code on the web which effectively appends the quesrystring, then runs a javascript redirect. On the second page the querystring is rechecked - if its go &js=1 then they're good, else they're not good. The result is put into session so I can carry it throughout the site.
The problem I have with this is that firstly I have to load the first page twice. However I then need to be able to get the session variable back again, which means this happens on the first page:
round 1 - page loads, checks if javascript has been tested or not. If not run redirect to itself.
round 2 - get querystring value and put into session.
However the page may then go on to load some javascript dependent controls, but session isnt picking up the javascript (probably due to the page life cycle)
I supose I could then go on to test the querystring as well, but it doesnt seem too elegant a solution.
I need to add the ability to register users in my web site. I'm sure that 1000's of programmers already did this, so why should I build from scratch? Does someone knows where can I find a module like this as well as other modules?
I need a few options on how I will allow a user to post simple text comments to my website page(s). I will require login to post comments in order to prevent spam posters.
I'm using Visual Web Developer 2010 to design my website. I'm not real familiar with it and do not know if it includes the tool I need to accomplish this task easily.
I have an application that I am writing in ASP.NET MVC 2 following the Nerd Dinner tutorial. I am very much a beginner and was looking for examples/tutorials I could follow that would enable me to learn how to code the following scenario:A user has the option to select an option from a dropdown.If the option is not there then they can enter a new option and add it to the database and list in the dropdown.
I would like this to be done without the user leaving the page and what they have entered so far.I am using a simple Entity Framework 4.0 model which I have built a repository on top of so I have methods I can call to save the filled in user information.If the entry already exists in the database then I would like to offer the user the chance to either select that entry or to continue adding the entry they request because it can be a list of names and of course you can have more than one person with the same name.
Are there any plans towards enabling the ability to render webcontrols (ootb) in a way that the javascript gets grouped in an external file and adding some sort of property to disable inline styling (e.g. validators using [Code]....
I wrote WCF service and i by creating new Web Sites - i added new WCF service that will host my WCF service.
In the 'Web location' i define the service to be HTTP and the URL to be "http://localhost/MyService"
Now i want to access thru some other machine ( in the same network ) to my machine and get using the Service method that my WCF service exposed - but i fail each time ( calling from the second machine "http://a.b.c.d/MyService/interfaceMethodName")
If i try to call the web service thru the same machine - i get the right response.
I'm researching the feasiblity of building the ability to browse a subversion repository from my web app. I'm developing in asp.net. I've read some mentions of WebDAV, but nothing that seems particularly concrete. Does anyone know anything about the protocol that is used to communicate with SVN? Or even better, a .net library that can do so.
I have an ASP.NET 3.5 intranet website which has a default page with a menu and when the user clicks on a menu item, I display the page for that menu item in an iframe embedded within the default page. but if the user types the URL of a page directly in the browser, then I would like to redirect him to the default page, because all the content pages do not have a menu. (Master Pages will solve this issue, but I can't use Master page here for a reason and don't want to go into those details). how to find out if user has arrived at the page directly by typing the URL or by clicking on the menu item, so that I can decide whether to redirect or not? Is this possible to find out? btw this is an intranet site and no login is required.
How do I give user's the ability to sign in using either their username or email address? How do I implement profile URLS so that domain.com/username Server.Transfers to ViewProfile.aspx?userID=342 How do I implement a multi-domain auth system for a single web app so that users can create the same username at different domains?
I just read the MSDN Magazines article on Dynamic Data and it got me wandering, could I use this in MVC3? Then with a little research the answer is yes, but you have to copy all these assemblies, modify the global.asax file etc. The same if one wanted to use web forms and MVC3. Wouldn't it just be easier to be able to choose a blend option when creating a new application in VS? My suggestion would be if one wanted to create a hybrid application that blended two different application styles, one could just choose multiple apps at the start, such as MVC3 and Dynamic data; and VS would just add or modify the necessary references so one could use the two development styles in a single application.
I realize that some would say this would probably defeat the purpose of the different styles, but if developers are gong to do it anyway, why not be supportive. What did Emerson say? "A foolish consistency is the hobgoblin of little minds".
When user start typing in their username in textBox field, a dropdown list shows old data. How can I clear this?. It's a class room and many students logs in from the same pc everyday, I don't want the student to see his mates usernames.
I have an SQL Server database.I am using Microsoft Visual Web Developer 2008 Express to develop my application. What I seem to be lacking is the ability to create reports. Is there any report generation software that will work with 2008 Express?
I am having trouble with something, my client wants to be able to hit <enter> as well as click the button on this page:-
[URL]
If you look at the Blue "Postcode search" and try searching for a nursery byb clicking the button you will see how it works. However then try doing the same but hitting <enter> and see what happens..
The front end html is as follows:-
PHP Code:
[code]....
I tried adding javascript so it would recognize the button and allow users to hit enter but this did not work.
I created a gridview that is made up of 4 gridviews and using a stored procedure to populate it. I create columns at runtime because the number of columns changes all the time.To make the grids editable I am adding template fields at runtime as I create the columns, this is to ensure that a user is able to edit the cells and some foot values update. Reason why I have four grids is to freeze rows and columns like in excel using javascript. The problem is that performance is very bad especially in IE, the grids take a long time to load. I am not sure if this is caused by the data load or the creation of text boxes. see some of the code below for my _aspx page:
I have this sample code for async operations (copied from the interwebs)
[Code]....
Other async approaches I tried required the aysnc page attribute, they also seemed to cancel if other page elements where actioned on (a button clicked), this approach just seemed to work.
I'd like to add a cancel ability and exception handling for the longRunningTask class, but don't erm, really know how.
I'm creating a composite control for a DropDownList (that also includes a Label). The idea being that I can use my control like a dropdown list, but also have it toss a Label onto the page in front of the DDL.
I have this working perfectly for TextBoxes, but am struggling with the DDL because of the Collection (or Datasource) component to populate the DDL. Basically I want to be able to do something like this: <ecc:MyDropDownList ID="AnimalType" runat="server" LabelText="this is what will be in the label"> <asp:ListItem Text="dog" Value="dog" /> <asp:ListItem Text="cat" Value="cat" /> </ecc:MyDropDownList>
The problem is, I'm not extending the DropDownList class for my control, so I can't simply work it with that magic. I need some pointers to figure out how I can turn my control (MyDropDownList), which is currently just a System.Web.UI.UserControl, into something that will accept List items within the tag and ideally, I'd like to be able to plug it into a datasource (the same functions that the regular DDL offers).
I tried with no luck just extending the regular DDL, but couldn't get the Label component to fly with it.
I'm writing a custom ASP.NET webcontrol and would like it to have a collection of custom items which can also be specified in the XML markup. Something like this:
class MyControl: WebControl { public IList<MyItemType> MyItems { get; private set; } }
How do I do this? I though this was all about implementing some interface on the collection or adding some special attributes to the property, but nothing I do seems to work.
I need to stop users users using the browser back button and potentially submitting an old version of a form.
I'm storing a guid in a session variable and also writing the value to a hidden form field and then checking the session value against the hidden field value if a user does try to navigate back and submit an old form.
If the form is submitted and the user wants to complete a new copy of the form then a new guid is generated both to the session and to the hidden form field. Now, if the user decides to hit the back button a few times to get the old form and tries to submit it again, the page checks the current guid in session against the guid stored in the form field and it finds a mismatch and prevents the form being submitted.
This works as expected in Chrome and Firefox, but in IE6, when the user hits the back button to view the old form, the new guid value appears in the hidden field of the old form! This means the user can submit the old form again, which we definitely do not want.
as all we know that we can create very simple chat using ajax timer & web service , it runs well for few users .
i want to leaverage same idea for site where 5000+ users will be there in chat room , messages are stored in queue hold in memory * dispatched as user request that is through java script timers calling page method or service ,
how well it will perform ? i know GTalk implements XMPP protocol(jabber) for the web chat seems it will be difficult to got XMPP way ?

The goal, from internal department (user) perspective:A department wants to "upload" an excel spreadsheet of data (product, term, rate, etc) to SQL (this will be from the internal network). The data is then saved to a webpage location for that department to view and approve. Once "approved," this data is displayed on the live web servers (public-facing website which is two load balancing servers). Bonus:
The .NET application/SQL Server can send an email to the department reminding them to upload the latest rates (each weekday morning, then each Thursday afternoon) if rates have not yet been "approved."
From the development perspective, this is my general idea, but I may be wrong.There are three spreadsheets, each with one tab. The first spreadsheet is uploaded, and the .NET application puts it in a SQL table. I then need to display this table of data on a .aspx page for the department to approve before the .aspx page is pushed to the live web servers.
First, I need an interface for this department to upload Excel files. I need this application to save the data to SQL and display it in a .aspx page so that the department can look it over and approve it. The department needs a way to "approve" the page, and this action will push the data to the live web servers. Will this involve SQL data transformation services?
I have an asp.net web app that uses forms-based authentication, a SqlMembershipProvider (using an encrypted password format), and a SqlRoleProvider. I need to know if it's possible to administer the users (create new users, assign them to roles, etc.) from a windows application - the powers that be don't want any administrative functionality in the web app itself.
Here is the membership provider definition from web.config:
[code]....
So, obviously, I have a Sql Server database that contains the users and roles for the web app. I'd like to create a separate windows app that references the web app assembly, and use the configured MembershipProvider, RoleProvider, and machineKey to create users, assign users to roles, etc. If that's not possible, I can duplicate the configuration settings from web.config within the windows app. But I don't know how to do this either.
