I would like to access the database through the code behind in C#.
Looking how to do this in VWD specifically. Does it go in a onload function? onclick? How does it work specifically in ASP.NET 3.5?
Using:
Visual Web Developer 2008, ASP.NET 3.5 with SQL Server Express 2005.
I have a lot of members data to enter into the ASPNETDB database. How can I read this data from an Access data file and input into the SQL database. All data is for user Names and Password,
View 1 RepliesI am using an SQL Express server hosted on a different machine and it is listed in my server explorer just fine. It is listed as my connection string in my web.config just fine as well and lastly it seems to sync just fine with my asp.net membership tables. My question is does it need to be listed in my app data folder of my site? Currently I have the ASPNETDB.mdf connection listed, which is apparently just a local sql express connection. The database I am using in my webconfig and other files is not listed so do I need to add it there?
Second question is about DAL, Data Access Layers. I have mostly been using presentation level SQL commands with my data presentation controls. Manually entering separate select, insert and update statements. I just went through a tutorial that stated the best way to interact with your database in asp.net is with DAL using table adapters. It mentioned that it gives you the ability to use strongly-typed references to each row. My question is can I use the same method multiple times on a single page. For instance a method inside an adapter named GetProductsByID(@ID) ? What if I want this bound to three different gridviews on a single page? Anyone have any other general things to point out about using DAL over presentation level commands?
I have a situation where I am accessing a database multiple times and I'm wondering if it is necessary.
I have a GridView with a template column with a hyperlink to "Get Results" and on the RowDataBound event I have it check the batch number against the database and see if results exist and then if they don't, hide the link.
So when viewing the page if there is 20 rows in the gridview it is effectively doing 20 queries.
I was wondering if it is a better idea to query the database once with all "batches" and load it into a datatable, then on the RowDataBound event query the datatable. The only issue I see with this is there is currently 40,000 batches and grows daily.
Now I'm developing web application with ASP.Net MVC but I have to use 3 databases. So I have no idea about this. I have to extract the data from 2 databases and I have to save the data to another 3rd database.

I am creating an insert statement in my c# code to insert records to an access database table. I am getting the error copied below using c# code. When I copy the generated insert statement from the console and run this on my access database, it succesfully appends a record in the table.Insert statement generated:

So what was the Connection String and can u give me the Example of that.
I am pulling a date from an Access Database and inserting into my Dataset. I am assigning it to "myDate" and then assigning it to my SQL parameter @StartDate.
When I run my ExecuteNonQuery I get a null value in my SQL database. There are no null values in my access database. I must have the syntax wrong.

In the development environment, in SSMSE > MyDatabase > Security > MyUser > Database role membership I have checked db_owner to allow me to build the database.
Now I am copying the database to the production environment I would like to lock the security down tightly. In the past (with classic ASP applications) I have only checked db_datawriter and db_datareader and, in Securables, checked Execute Grant on the stored procedures.
In Database > Securables I add my stored procedures and check Execute/Grant for each of them and click OK. When I return to the securables page the stored procedures are no longer listed.
I have noticed that nothing is listed in Effective Permissions and I think it should list Execute. If this is the problem, how do I add Execute to the Effective Permissions list?
In remote db, I can be able to connect ms sql db as localhost in my connection string like below,
<
add
name="ConnectionString"
connectionString="Data
Source=localhost;Initial Catalog=DBServer;Persist Security Info=True;User ID=sa;Password=*****"
providerName="System.Data.SqlClient"
/>
This is running in server and its working fine.
If i want to make any changes in db structure or need to modify any data values, i have to login remotely to my server and has to open sql server management studio do db change or value editing stuffs. Its really getting iritating when the remote machine looks slow.
I just want to know how to configure the db hostname like dbname.domainname.com or mssql.domainname.com in server, so that we can open the server db in local using sql server management studio.
The application installed in windows server 2008 and using IIS 7.0 & SQL Server 2008
I have only little knowledge in server.
I'm trying to figure out if it's possible to transfer records from SQL central database (who has a public IP address) into SQL local database (who doesn't have a public IP)?
or if it's not possible can I use a centralized website instead to pass some data into the local website? (but i'm not sure if it will have some security concerns)..
i would like to ask about how to sync data from client sybase database import to our sql server database regularly(set time to sync everyday) by create a file in our sql server database

I'm now reading this article:[URL]But I don't understnad why this is better than just writing code, methods that connects to DB and get from stored procedore what I need.
Why is it better to use so much DataSets for all the tables and more.
I am having some difficulties with a particular task. I am creating a support desk intranet application and I am trying to write a method within a class within a namespace which will form a generic database connection which can be called from any of the aspx pages so that I have the dbconnection logic in one place; you know, going along with the 'DRY' (Don't Repeat Yourself) mantra.
The Namespace:
SUPPORTDESK.SQL.dbconnection.pullData()
Objective of the method:
To provide any aspx code behind file with an SQL Server 2005 Express Connection and if possible return the data from an SQL Query. This is where I need advice do I create the method such that it simply forms the connection and returns a DataSet or that it returns an SQLConnection object? If i've got things back to front and upside down don't worry I'm a beginner with ASP.NET. The Method so far:
[Code]....
If I'm on the right track how do I access the data returned in the DataSet?
I can use similar code below to select a row in my database when I enter a value (username) in text box and it successfully retrieves.however, I'd also like to delete row from database based on the username i enter in text box. My code runs but no row is deleted...my code is:
SQL:
private AdminTableAdapter adminGetUsers;
I am new to MVC and this really probably should not be posted here but in a different forum topic. The reason I am posting here though is I am not sure if there is something about MVC that would prevent me from doing what I am looking to do.So here it goes.Maybe I am the only one out there that thinks this way but I don't care for and don't fully understand LINQ. I Like building my stored procedures passing my data to a datareader etc... and displaying what I need.
Now that being said I am wanting to learn how to make a true Data Repository and build from there but everything I find online especially here all gives me examples and instructions on how to do so using LINQ.Does anyone know of a site that will teach me how to do this without using LINQ or any form of ORM just allow me to write my stored procs how they need to be and build my classes for data access how they need to be.I may be wrong in this but it seems to me this would be the more light weight way of doing it.Anyhow as stated above the additional question to this would be is there any reason this would not work for MVC and actually any reason it is extremely (or at least for me) hard to find any documentation on this anywhere online?
I keep all of my code in codeLib.cs and use it on various ASP.NET pages. However, I still have to do the databind(); in the code behind page for each aspx file. How can I eliminate all code in the aspx file so I just have the UI in the aspxand the code and databind(); in codeLib.cs.

I have a problem and I could not solve it. Hope you can write a sample code for me. I have a Microsoft Access database, and in asp.net website, i draw a grid view on the design page. I also configure the source data access. It works, but display all the data in the database. i want to display all the data which is related to John. sql = "select username, customer_name, phone from db where username = John" how do i configure the data grid view?
View 3 RepliesAre there scenarios where it makes sense to encapsulate a data access layer (of a ASP.NET webapplication) with WCF or WCF Data Services ? Makes it sense to use a service inside the application ?
View 2 RepliesI can't seem to access a label that is outside the DataList. I wish to add the data in the label into a database, aswell as data that is inside the datalist (this is already working though). My SQL-query with only the specific label looks like this at the moment:
[Code]....
The data is added to the database when pressing a button inside the datalist (using onItemCommand). If I write UserIDLabel.Text the regular way it doesn't work either. The label is in the MasterPage, while the datalist is in a .aspx-page. If it is possible to somehow access the data that is in this label and add it to the database I would be ever grateful. Or is it somehow possible to add data that is in a Session and add it to the database?
