CMS/E-commerce .net Project : One Database Or Multiple Databases?

Mar 31, 2010

I'm currently working on an C#/ASP.NET project that will host several differents e-commerce websites, all running in the same application.I use LinqToSql (moving to PLINQO soon) to access my database. The database contains both informations on the website structure (pages, ...) and the products/orders/users data.

My question is, should I use only one database for all the websites, or sould I create a new database (same model) for every new website?I'm now using a single database (with SiteIDs in some tables) but I have a big security concern, I can't just backup/restore the database for ONE website if something goes wrong (e.g. somebody erase all the products on ONE website) and it's an important requirment of the application.

So I was wondering what are the good practices in that case? Is there big cons if splitting dbs?(I would have to make changes to several database instead of one in case of structural changes, but i guess i can make a db version/update system).How the existing CRMs are dealing with that?Is it a performance problem if a database server host a lot of different DataBases? A complex backup/restore tool would be better?

Subquestion:To make a website replication easy, I can also split the pure CMS data (Pages, Texts, ...) in one DB and the e-commerce data (products/categories/orders in another). It can be achieved by some select/insert functions but it would be easier by just copying a database of course.

Visual Studio :: Convert Single Project Website Into Using Multiple?

Jan 9, 2011

My website uses a single project solution. Each web page file consists of C# code along with the markup. I now have to separate the code from each page into code-behind files that must be combined with many different versions of the markup. I assume this means that I will need a solution with a common project of code-behind files that is merged with a project of each version of the markup files in order to create different websites. I need to know how to organize the solution for debugging and building each website and where to place each file.

Managing Multiple Languages In A Web Application?

Apr 19, 2010

I am part of a development team building a new ASP.NET 3.5 web application. Two of us are C# coders, and the other is a VB.NET coder.

I know that we can mix languages on a per-project basis, and one can build classes in one language that inherit from classes written in the other language in a different project (which we are already doing), but I can see us getting into a situation where we might well end up with cyclic dependencies between our various project DLLs.

Other than simply having a high number of projects (more seperation of concerns into more libraries), how have you managed this situation on your own projects?

Note - I believe this question to be different enough from the only similar match I could find (this one) on the basis that we are not wanting to use different languages in order to take advantage of their specific features per se, but rather to make use of what developer resource is available to us (i.e. one dev just happens to be VB.NET only).

Configuration :: Managing A .net Site Across Multiple Servers

Mar 28, 2011

A friend and I manage a large website for a company. The site is build using Visual Studio 2005 and is a series of nested web applications run inside a master application employing nested master pages. Currently we have to manually move files around folders and FTP them to various servers and I am looking for a way to be able to manage the deployment end of the site in a more automated fashion. I'd like to be able to work on my local version of a project and once I'm done be able to hit one button and publish the site to our internal testing server and then when testing is complete hit another button to deploy it to the live web servers. Right now we have to manually navigate the windows folders and copy pages, css files, images, swfs, etc and FTP them manually. The driver for this is that we have a new junior develop starting and want to remove the manual aspect in advance of him starting.

State Management :: Managing Session In Multiple Tab In The Same Browser?

May 26, 2010

I am sorry if this is been discussed earlier. I am having a problem maintaining the session when someone uses the same browser with multiple tab, the results gets messed up. A perfect example would be, [URL] if you open IE (or any other browser) and open two tabs and search for two different air travel itinerary and the results will completely overlapped (real mess). I know the cause for this problem (both tabs uses the same session). I would appreciate if somebody have any solution for this. I am using ASP.NET 3.5/VS 2008/VB.NETI will not be able to use Viewstate since I use a master page and pre-init event where view state is not available.

Forms Data Controls :: Using Multiple Tables Within A Single DataSet And Single SqlDataSource?

May 19, 2010

I have a stored procedure that returns 3 tables within the single recordset it returns. If I set a SqlDataSource to get data from this procedure, it works, but it only returns the first table. I want to have a GridView display the data from the 2nd or 3rd table using a SqlDataSource, but I can't figure out how to specify a particular table.

While there are some posts discussing this out there, I can't get a definitive answer about whether or not this is even possible (?). In a worst-case scenario, I can create another SP that only returns the 3rd table - but that creates a little maintenance headache that I would prefer to avoid.

C# - Migrating From Website Project To Web Application Project In Visual Studio 2010 Causing All Controls To Throw Error?

Mar 29, 2011

I recently updated my VS2010 website project from .NET 3.5 to 4.0. Everything was working fine in the website project. Today I decided to migrate the website to a web application project as I have learned this is the best way to work in .NET. I split out all my class files into a separate class library and copied all my other content into my new project. Then I updated all the references and web.config.

When I build the class library, everything works great. The problem is happening when I try to build/debug the web application project. It is acting like all the controls are missing and it is also throwing a bunch of compile errors about the public properties I have in my master pages.

Control errors: "The name 'INSERT CONTROL NAME HERE' does not exist in the current context"

Master page errors:'System.Web.UI.MasterPage' does not contain a definition....

It is giving these errors for every single control and master page property in my entire solution.I notice when I add a new web.form to this project, it also adds a filename.aspx.designer.cs file in addition to the .aspx and .aspx.cs file. My existing files do not have these extra files since they were created in a different .NET version.

UPDATE: It seems I was missing the step where I need to right click on the new application folder and select "Convert to web application". I just did that and it seems to be a little bit better...

Now it is choking on Literals that are inside single quotes:

<div class='<asp:Literal ID="CssClassLiteral" runat="server"></asp:Literal>'>

It doesn't see this literal when it does the conversion... Is the above valid code or should I implement that functionality another way?

VS 2010 Web Service - Single Sign On (SSO)

Jun 20, 2011

I've only worked with web services a little bit. I am working on a project now using another developer's code as a template. It is code for a single sign on (SSO).

Here is a code excerpt:

namespace xxxxxxxSSO {
/// <summary>
/// Summary description for xxxx
/// </summary>
[WebService(Namespace = "http://tempuri.org/")]

[Code] ....

Also let me say, I have been coding in VB6/VB.NET for the past six years and am learning C# (that is what the other developer's code is written in).

setAppCredentials() is the beginning of a lot of sub-calls and I have gotten that all to work when I was running the service from within its own Visual Studio project.

Where I am having the problem is setting credentialHeader.Username and credentialHeader.Password. credentialHeader is nothing when I call validateCredentials().

I didn't see how I had these exposed to me in order to set them. So the developer said Create a client that consumes that service and set the values there and call your method.. But I still don't see how it's exposed to my consumer. I have this line of code in the consumer

Code : Dim myWebService As New localhost.xxxMemberService

(Back to VB!,) but I still don't see credentialHeader exposed.

The only other thing I see in the webservice code that might be relevant is this:

/// <remarks/>
[System.CodeDom.Compiler.GeneratedCodeAttribute("System.Xml", "4.0.30319.1")]

[Code] ....

which is in a file called referenes.cs.
