View 1 RepliesI'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)..

View 1 Repliesnew to this forum, and visual studio web development. Here is what I want to do: -From a webpage on my website, I would like to upload multiple photos to an sql database, but instead of having a container or field name for each photo, i would like to have multiple photos on one field, on each record.Then, I would like to display it back one record at a time, but with the capability of displaying all the pics from the one field holding the pics. Similar to the function in MS Access, where I can upload mutiple photos in one field and then display them back by just scrolling through them on the same record.
View 2 RepliesI was just wondering that when we insert some datainto database we can use the following method.
create a sql datasourse ,
set the conection string,
set the insert comand type,
set insert parameters,
and Set the SQL Statement like
sqldatasource.insertStatement="insert into tablename(field1, field2) values(@parameter1, @parameter2)";
and then call the datasourse insert() function,
this method is usually used for single line insertion at the end of the DB.
Now I am a starter in asp.net c#,
I want to know that if There is a way that I have lots of data like some XML file that have the same table structure as the SQL database table
and I want to write that data to the database, HOw to do it Properly,
I can Still achieve the required results by iterating through XML datarows and for each row conecting to db and inserting and then disconecting dfrom the db,
But I want to know that if there is a way to do it in one go meaning I have to conect to database only one time,
Note: I already have some data in my SQL table, there are three fields(ID Name and Nickname) the ID(primary key) is INT type and auto incremented, the name and nickname are strigns.
the xml file has the structure
<userdata>
<user>
<name>michel</name>
<nickname>micho</nickname>
</user>
</userdata>
Whenever I run the following code to insert a record into database:
protected void Button1_Click(object sender, EventArgs e)
We have a ASP.NET 3.5 application where we want each user to have their own database. Everyone uses the same web application, but the database their data is kept separate from all others. So every customer has his own database. All database structures are identical, so the only thing the application has to do is connect to the right one when the user logs in.
I envision that we look up a connectionstring to their data at the time they log in and set it globally for that session. With Linq, the connection is handled automatically though, in the background, based on the setting in the web.config file. Unlike SQL Server where you set it each time you use it, with Linq it is hidden in the .NET generated class files. So how do we make this vary by user, while using the same application for everyone?
i am trying to read data of from a sql database
the code that im using is as follows:
[Code]....
as you can see, im using table adapters - though when i run the page, it throughs me the following error, which i'm finding hard to understand
for my last project, i had to use the exact code, but at the time, i was using an access DB and now i'm uning sql D|B
the only difference from last time is that instead of using :
using System.Data.OleDb;
Now im using: using System.Data.SqlClient; //sql server
I have this code and not sure what is wrong.
csconnection = New OleDbConnection (Stringconnection)
cscommand = new OleDbCommand("INSERT INTO Login ([Username], [Password], [Name], [DOB], [Gender], [Nationality]) VALUES (@Username, @Password, @Name, @Dob, @Gender, @Nationality);") [code]...
it just says errorat bottom of page and is there a way to tell the webpage to show me the error.

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?
Is linq just for retrieving data or can you send data to the database using it?
