While working with LINQ to ENTITIES I see that there is only a way to use stored procedure that is returning one entity only, or a view that is a join of two entities.
But what if I need in ASPX page to get two tables that there is NO connection between them, no join can be done between them at all.
I have one Stored Procedure that return the two tables, but entities don't support this right now.
I can split them to two Stored Procedure and call each of them separately.

I am trying to populate a drop down list from my controller for a create action. I can display the dropdown as I want but when I cannot get the value to be stored in the database. My models:
[Code]....
Controller: [Code]....
View: [Code]....
This above snippet will show me the message "The value '50117dae-a7d7-4371-926f-7b1f7aaec133' is invalid."
if I change the line to @Html.DropDownListFor(ct => ct.CollectionType.CollectionTypeId, new SelectList(ViewBag.CollectionTypes as System.Collections.IEnumerable, "CollectionTypeId", "Title"))
@Html.ValidationMessageFor(model => model.CollectionType)
the page will not do anything - I believe this could be because the controller is trying to add a new CollectionType.

I'm building an online file management system for a certain workflow. One of the services of this system should be as follows:
whenever a fax is received, it should be saved in a certain table in the database as a PDF file.
I'm using ASP.NET with C# ..
Is it possible to perform that task without the need for a middle desktop application?

I come from a coldfusion background, where setting up a connection to a database (Oracle, MYSQL SQL Server etc) was was easy as filling in a few fields in the datasource screen in the Coldfusion Administrator web app.
Then in the web application to connect to the database I would use <CFQUERY datasource="oracledb" name="test"> and in the body of the application I would write my SQL query and display the results of this query in a <CFOUTPUT>#variablename#</cfoutput> block of code, or to insert data into a db table I would use the
<CFQUERY datasource="oracledb" name="insertdata">
INSERT INTO table (columnname, columnname2, columnname3)
VALUES (
<cfqueryparam cfsqltype="cf_sql_number" value="#columnname#">,
<cfqueryparam cfsqltype="cf_sql_varchar" value="#columnname2#">,
<cfif isdefined("file.serverFile")>'#file.serverFile#'<cfelse>NULL</cfif>,
</cfquery>
How does this process work in .NET? as I have to create a simple web application/form where on submission of the form the data would be stored in a MYSQL database.
what I have seen so far it seems a far more long winded and complicated process with .NET over Coldfusion with ultimately the same result, and I am desperately trying to understand how it works in .NET as surely it must be a similar process to that of Coldfusion?

I have developed a web application in asp.net with C# in visual Studio 2005. And i used sql server 2008 as back end. When i run the program, it shows the following error..An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)

I'm trying to learn how to do both of them at the same time on my own, while working on a project. All the examples in the MSDN are using databases that are a local SQL Server (Express) file. I am not going to be able to just upload the project (including the file) and have it work, am I? The thing is - I want to be able to write code vs. a database that is actually going to work online so I can start putting a project together and know that it is going to work online.
I don't want to get everything done, and then discover it breaks as soon as I upload everything. Assuming I can't just upload the database file and have it work - I have a hosting account that I am using for something else and I would like to set up a database to use (preferably MySQL because my SQL Server database quota is used up and I'd have to pay extra for another, but I will if I have to because it's not that much). I can do that, correct?

I have never used reporting services before. My boss just started teaching me how to use them. I was told something by my boss that I find hard to believe. In our environment we have 3 databases: Development Beta Production According to my boss, the connection string has to be hard coded in the reports. Therefore every time you move a report from one environment to another you have to manually change the connection string so that it points to the correct database.

I currently have an internal system that I need to link up to an API offered by a company. I am not looking for hand-holding on this, I really need to understand where and how to get started really.
Here is the developer resource for the API I am looking to work with:
[URL]
Further, my systems are currently in ASP/ASP.NET & SQL, and I'm familiar with VB so I would rather stay that direction instead of C#.

I've installed the Components from the links below. But I still can't find any SQL references when I try to add them? I'm wondering if anyone would know the reason for this? I just started with asp.net. I've found several other questions regarding code for connecting but I can't find anyone who've had trouble with the Connector/components before?

how do i connect visual web developer to sql server express 2008? in the Database Explorer, i right click on Data Connections, click Add Connection..., and in the Data source box i choose Microsoft SQL Server (sqlClient), which i'm guessing doesn't connect me to a database file, but to sql server express itself(?). in the server name box when i click the drop down box, there's nothing there and that's where i get stuck.

There is a website that I've programmed that sometimes takes a long time to load. I will click on a browser bookmark to load the page which should take me to a login page. The code that the Page_Loads for the MasterPage and the initial Login page contain is minimal; no service, database, etc. executions. I even just commented everything out and the problem remains. Sometimes it takes 5/10/maybe more seconds for the simple Login page to load. I'm trying to figure out what the issue is, but I'm having a hard time. When I put breaks on the Page_Loads and debug, it loads immediately. Then, seemingly randomly sometime after that, it will again load slowly.
It wouldn't seem like any of my code is the issue since, when I debug, it loads quickly. I'm not calling any services or database methods so, AFAIC, that can't be the issue. I separated all of my websites in my IIS to use their own app pool the other day so if there is a memory leak in another site, it won't affect this one. The only thing I can think of now is some issue with my network which I wouldn't have the slightest clue at starting to debug. I can have IT investigate, of course, is that is a probable cause.

I've a problem with my web application. I hosted a web site in IIS and initially its working good. After sometime ( i dont know the time diff exactly ), if i try to access my page its not working and after re-starting my application only its working. Let me explain about my project.
I've only 4 pages ( ex: main, a1,b1,c1 ) in my site. In main page i used IFrame to show other 3 pages by clicking the appropriate tab. Before this main page load, i'm connecting to DB (Oracle 10g) and i used "System.Data.OracleClient" class to communicate with oracle. Every time after retrieved data from DB i'll close the connection. Then i'll display the main page and assign other page url's to the tab.
Now the problem is after sometime if i access the main page, its not connecting to DB at all then i'll show some static message like "site is unavailable at this time". And i'm not using connection pooling concept. And also this problem is not occurring all time.

I'm trying to write a method in VB.net so that when I click a button it queries the database and returns all the values which match a textbox which is located next to the button. I have no idea how to do this, I assume in the onclick method for the button I will need to pull in the value from the textbox, connect to the database and display the results to a gridview?

I'm trying to connect my app to my database hosted on my web space. I have a newbie query.Do I have to install Connector/Net 6.8.3 on my web space's server, or, can I install it locally and just change a config file of some sort on my server version? If the latter is possible, what is my best (and easiest) way of developing / testing in two DB environments? the testing server will be my online one so I don't mind having to manually edit something each time after I publish it.
