I've got an ASP.NET web project which connect to an SQL Server 2005 DataBase.I think that I'm doing the part of the database connection awfull because everytime I need to do a query (select for example) I'm creating a new connection, opening the connection, creating the command, executing the query, using the results and closing the connection.
Is the rigth way to open a connection in the start of the application and closing at the end?? How can I do that?? I'm retrieving data but what will happen to database server when the application will be used by many people?
I'm having a terrible time being able to connect my access database to my website. I'm using 1and1.com as my host. The database resides in my App_Data folder. I checked everything I could think of on the host side. I cannot query from the database through VWD Express nor create a typed dataset .xsd that will allow quering the database.p.s. - I don't need any sophisticated security on the database, just a homegrown sign in I put together that works fine for my site which is mostly xml file data.

I have a database on Go Daddy and my VS2008 app can not access it via web.config connection string. Of course runs great locally in development. I copy/pasted the connection string information from Go Daddy exactly into my web.config file. Web site runs fine on the web but when I try to Login at my login page, i get :The SSE Provider did not find the database file specified in the connection string. At the configured trust level (below High trust level), the SSE provider can not automatically create the database file.
I used VS2008 to create the .sql script files and uploaded them to Go Daddy and the Go Daddy people say everything works as they and I can both Login to the database from within GoDaddy.The database i am trying to access consists of the a ASPNETDB.mdf and another Database.mdf together as one in the Go Daddy database.
here is what i used: <connectionStrings><add name="superskin" connectionString="Data
just for my testing purpose i know i can define both the connection's outside in a single web config file by different name's and access them in my front end according to it but what if i want to have seprate for both connection's web.config situation is like this see image so i want to access my connections from second web config file how i can do that.
I am using VS2008 and oracle 10g ODP.Net. The oracle database that I used in the connection is working and tested it using sql plus.The connection string when used in a GriDView works perfectly. Now when I created a new listview control with the same connection it gives an error.Database schema could not be retrieved for this connection. Please make sure connection settings are correct and the database is online

Is there anything missing in IIS 6.0 that prevents me from (Insert into table) using MS-Access?
Explain: The application works fine under Visual Studio 2008 IDE the insert into table works fine with no error, Also I tested with hosting provider and works fine with no problem. but now I have published the same exact app in a dedicated server windows 2003 with IIS 6.0 .NET framework 2.0 with latest service pack I gave IIS_WPG write/modify access to the folder where MS-Access database is located and database but at the time of insert an error pop-up. I need to install in the Server or settings in the IIS to recognize my MS-Access db is it some office runtime that I am missing. (BTW I am using OLEDB connection string in my C# )
Using System.Data.OleDb;
I can retrieve data off of it with no problem but when I try to insert is when it fails I thought the problem was Access Rights but I do not think is the case.

I have a page on which I generate a load of html which is used in a html email.
Here is a bit of the code ...
Code:
[code]....
Because of the problems getting the email to look the same in various email clients, I need to convert that chunk of html to a pdf - so I can create the pdf on the fly, save it and attach it to the email.
Can anyone suggest a simple pdf generator that will just take a chunk of html and create a pdf from it? The ones I have looked at so far have what looks like a steep learning curve with hundreds of features I don't need.
trying to switch to better coding practises, I am totally confused about which path to choose. For the past year I was just coding through classic asp coding methodology. Now I know about things as
3 tier custom 3 tier with Strongly typed data sets N tier applications Custom entity objects and so on
Can someone recommend me an approach for designing web applications from these? Some book or tutorial reference with simple CRUD application that would help me. I am currently stuck with strongly typed data sets as I cant find CRUD tutorials with that approach. I would like to just choose the right approach and build on it.
I'm thinking of using ASP.NET and MySQL together on a large project. Does anyone have any experience in using these two on a large scale and are there any aspects I should be wary of? If there is a chance that there could be compatibility issues, then I may be prepared to purchase an MSSQL license, but I'd rather go the free route right now. In theory it's possible, but how easy is it to transfer a MySQL database to and MSSQL database in the future?(I'll make this a CW if requested).
I have a folder that contains lots an lots of pictures, videos, whatever and I only want people who are on my SQL08 to have access to it.Someone recommended Forms Authentication, but that seems to only open up its own aspx pages.Am I configuring it wrong or should I be using something else?
How can i get ConnectionString In web.Config when you are in DAL(data access layer)Some said it should me in <appSetting> but i think this is not appropriate to do because web.config have dedicate tag for connection strings.i am creating a 3 tier each layers is a project in 1 solution

I have created a website (VB) on my local host. A couple of pages on this website use gridviews or detailsviews with an AccessDataSource connection to a MS Access database. This works perfectly. But now I want to move this website to a hosting provider. And on this hosting provider my website works well but not the pages with a connection to the Access database. I searched the whole internet for a solution but I didn't found it.
Folder structure on the host:
- db > Access databases (name: testdemo.mdb) - logs -wwwroot > website (for example, the gridview is placed on index.aspx).
I think AccessDataSource didn't work, but what kind of code may I use in the index.aspx and web.config? My hosting provider said only, use a direct link to the database and not a relative, for example: E:xxx.comdb estdemo.mdb
I need help with changing this DSN to a DSN less var connection .whenever i use the dsnless connection i get an error since the String connTaftPrjPic is reused in the code.The Objective is to change to a DSN Less connection without affecting the connTaftPrjPic.
I'm using Visual Studio 2008, and my database is SQL Server 2000.
I want to add a connection to the Server Explorer in VS. The Data source is Microsoft SQL Server (SqlClient). After entering in all my information and I click Test Connection, it is successful.
But when I click OK, I get the error:
Unable to add data connection. ExecuteScalar requires an open and available connection. The connection's current state is closed.
Does anyone have any applications that they recommend, whether they be downloadable or web apps, that can neatly format your .aspx code? I've had limited success trying to adjust the formatting preferences with Visual Studio itself, and spend a lot of time manually indenting/unindenting lines.
As a clarification, I'm looking for something to format the web page code, not the vb code-behind file.
