I haven't developed in ASP.NET for a very big while...
I'd like to create a website that will enable members to add content : let's imagine they have items to be sold, and they want to create one web page for each item to be sold. Those pages should be viewable by everybody, but should be editable only by the member who has created it of course. Each item should be stored in a category. In fact it's very similar to what eBay does (except it's not for auction at all), or maybe a site for classified advertisements like www.adoos.co.uk is a best example.
The application should be dimensioned to allow potentially millions of members, with few items (around 1-10) for each member.
I imagine to use the ASP.NET Membership Fx to manage security and user account, stored in SQL Server. Is it a good start?
But I don't have any idea about where and how to store the content itself (user's web pages, with optionally few photos)! In SQL Server? In Active Directory, how? Is a CMS framework the right tool to be used?
I have a UserControl that has some javascript I'd like to inject into a known ContentPlaceHolder.
I was hoping to do something like the following except when I append to add the control to found control I get an exception which says I cannot modify the control collection in the Init, Load or PreRender events:
My prior asp.net apps used windows authentication on an intranet. Now I'm developing an app for the internet and am stumbling over how to properly manage user sessions and state.
I first developed my web site functionality; created the SQL DB and got all of the pages to properly handle the data. Then, I installed the SQL Membership database and was able to get the CreateUser, Login, Logout pages to work. On the Verify process for the Userid, I added a step that will take the membership UserId value and create a Company record in my tables and link my CompanyId key with the UserId.
At Login time, I create a CompanyId session variable; each page uses it to retrieve records for the user. When Session Timeout occurs and the user click a link to another page, the app redirects properly to a Login page. However, if the time expires and then the user interacts on that same page, 'Object not set to an instance of the object' - the CompanyId session variable has expired.
What is the proper way to handle this? I'd like the page to automatically redirect to a TimedOut page (this would happen automatically without the user doing anything).
I considered writing a Function where I pass the Session variable I want and the Function sees if it exists; if it doesn't it would do a Response.Redirect to the TimedOut page...I can't get the Redirect to work in a Class Function ('reference to a non-shared member...').
I assumed that I should set CompanyId as a Session Variable so each page knows the user to get data for. Another approach is to use the membership User and if it is still valid, do a DB lookup to get the CompanyId. I did not choose this because I felt that it would increase DB traffic and web traffic.
Here are several relevant settings from my web.config:
I am working on a web application and in ASp.Net using VB.net. The requirement is to create a csv file on the server and the user should be able to save the file on his machine. I am creating a csv file on the server and throwing the contents of the csv file to the user using Response.Write method.The problem I am facing is instead the csv file content, user is getting the html code of the page which he is accessing I wrote the following code in my aspx.vb :
strPhysicalPath = Server.MapPath("CSV/" & PathVirtual) appendFileContents(AppStartupPath, "strPhysicalPath : " & strPhysicalPath) Dim objFileInfo As System.IO.FileInfo objFileInfo = New System.IO.FileInfo(strPhysicalPath) Response.Clear()
How can I get the csv content in the file that is being downloaded by the user?
I have to develop a web application (planning to do it with asp).The customer want to have the access to manage the website content without need to contact the developper for that easy task (adding text and pictures essentially based on user authentication).Is there any mean to do it rapidly ?
I have considered to use CMS (Sitefinity , DNN ..) to have the content managemnet capbility and to have the out of box modules , but I still fear the fact I will not have total control to see the all code done by the CMS. For exemple , you cannot (I am may be wrong ) add a .aspx form with a code behind in Sitefinity 4.0,
Is there any modules that could be used in .net (may be web parts : I am still reading about it) ?
I'm using the ASP.NET 4.0 ASP.NET application. It comes wired up for menu, login, roles, etc. This question is about placing a user control (which just contains a label with Copyright info, always at the bottom of the page. It found the Site.css entry to make the border it puts around the content always the same size - so it's consistent on every page, but I've not found how to make the user control stick to the bottom of the page. Right now I use the "footer" class which auto centers the content in the user control, but nothing to make it appear at the bottom of the page, without putting a bunch of <br> tags (a different number of them for each page, to keep the user control at the bottom. I've currently putting the user control inside <div class="footer"> which picks up the centering from the Site.css.
I have a control that I want to be able to mark areas as editable. When a user enters a username and password, they can then edit these editable areas.One of the area to edit is the main content of the page. Since I want them to be able to edit this on every page, I have put the editable control into the master page, wrapped around the ContentPlaceHolder of the master page.I found out how to allow the parser to allow <prefix:tag></prefix:tag> rather than just ending it with />, but I can't figure out how to get the text within the tags to be accessible through something like a Text property. A prime example of this behavior is the Label control, where you can put <asp:Label>Hello!</asp:Label> and access Hello! through the .Text property in the code.
Is there a good way to enable forms that come out of user content (CMS) that is displayed inside the form runat="server" tag? All sorts of services provide forms for users to paste into their website, which break if the content ends up inside a .net form. It seems to me that there must be a good way around this, but I can't seem to find any solutions.
I have designed program to display live events/content(like online orders in shop) at different location. Now case is, suppose Some of Clients putting order for material and suddenly Internet gets disconnect.So what I am looking for, in this case, I want to show some default text/images to End user who is trying to put orders. I am ready to design to Desktop Application to do this, but I need inputs on how to achieve this at User end?
I have a USER CONTROL with a <div> tag and a button. I want to print the content of the <div> when the button is clicked. Only the content of the div and nothing else no matter where the control is used. This without opening a new window.
I have a web page using MasterPages built in Visual Studio 2010 Pro. Currently, in the Head of my MasterPage file, I have my reference to my jQuery 1.4.2 file. When I go to a content page referencing the MasterPage I don't get any jQuery intellisense support. (Looks like I just get JS support?) What is more frustrating is the lack of Intellisense in my User Controls (.ascx) - It makes sense though since VS has no idea knowing if my UC will be loaded into a MasterPage referencing the jQuery.
My Scripts folder has one file - jquery-1.4.2.min.js
I have a form in user control which submits data in database and clicking button. how to attach this button press even directly in the aspx page. I do not want to make delegate and want to use default event.
On my master page , I have "Search textbox" and "Search Button".On My content page , I have a "User Control" which has a "GridView".It shows some data about Vendors.Also, on this User Control's Page Load, i have code written to display all vendors in GridView.Now, when user enters Vendor Number in "Search textbox" , and hits "Search Button" , i want to handle this event inside my User Control.How to do this ?
I have a master page with a user control on it. How do I change the user control's properties from a content page?In my ascx file I created this 2 property:
I am having an issue, with the membership and form authentication. I am having a problem where when an logged in user types a url they can see the content of pages they're not suppose to. When the user tries to click on the screen or any ajax fires they are redirected to the main page. What is going on? I have all the items setup in the webconfig properly just wondering what is happening. Also I don't want to use a redirect solution for each page since that is what I thought webconfig was setup for.
HiMy web site uses 2 unmanaged DLLs (gsl.dll, cblas.dll). I put these dll's in the bin folder along with some other managed dll's. On my development system everything is fine when using the built-in dev server in Visual Studio 2010. However, when I run the site through my dev system's IIS instead of the Visual Studio server I get the following error:'C:<absolute path to bin folder>ingsl.dll': Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED))
