im trying to get a dataset from an access databaseim using this connection string:
<connectionStrings>
<add name="SiteConnString" connectionString="Data Source=c:inetpubvhostsdbmainDB.mdb"
providerName="Microsoft.Jet.OLEDB.4.0" />
</connectionStrings>

When I am trying to insert some data I am getting error.
Could not find file 'C:WINDOWSsystem32ikcit.mdb'.
Unable to understand Why??
I keep getting a
InvalidOperationException: ExecuteReader requires an open and available Connection. The connection's current state is closed.]
It is because my connection is closed. What is wrong with my connection string? Why won't it open.

trying to connect an access db (.mdb) to a gridview control. the db is in a folder under my iis wwwroot folder. when setting it up i can test the connection ok, but when i go to save it, it comes back with 'the system cannot find the file specified'?
if it can test the connection ok how come it can't find the file? for the connection to test ok obviously the path must be right is there some restriction that the db has to be in the app_data folder? i notice when creating the data source and selecting browse, the only folder it displays and allows you to choose from is app_data. thats pretty restrictive and then makes it more difficult if that has to change when moving from development to production. is there some way to connect to a db outside of the project?
I having worked with asp.net in while.Working in VS 2008 it seems it embeds the database in the solution.I have a external database,that is used by other applications.How do I connect into that?
View 2 RepliesIīm learning how to use a web service with flash.
Now I need to connect the web service to my db.
This is what I tried:
Code:
Public Function HelloWorld() As String
Dim orgcon As New OLEDBConnection("Provider=Microsoft.jet.oledb.4.0;data source=c:dataDB.MDB")
Dim OrgDA As New OleDbDataAdapter("select * from organization order by orgname", orgcon)
Dim Orgds As New System.Data.DataSet
OrgDA.Fill(Orgds, "Organization")
Dim hwstring As String
hwstring = orgds.tables(0).rows(0).item(3).tostring
Return hwstring
End Function
The flash just gives me an error that there was an error opening the web service. For some reason I canīt debug it in vwd.
I have a task in which i have to compare 2 access databases
and in these 2 databases, there is a field "Customer_Name" Let's name both databases as DatabaseA and DatabaseB
In DatabaseA there is a list of Customer_Name that includes all the customers
Now I have to match this CustomerList with "Customer_Name" field present in DatabaseB
If Customer Name of DatabaseA is present in Customer Name of DatabaseB then leave it as it is
If Customer Name of DatabaseA is not present in Customer Neme of DatabaseB then rename the name of that customer as "NA" in DatabaseA'S Customer Name field
So i have to perform these 2 above mentioned things, is it possible to do it in asp.net coding ? just with a press of button (in button click even) to save time as the list of customers includes 3000 customers approx

View 1 RepliesI have created a web application and an SQL database using Web Developer 2010 Express. I have SQL Server 2008 and SQL Server Management Studio Express. In order to deploy the database to my hosting space I need to create a .BAK file from my new database. I think I can do this from with the Management Studio, but can't figure out how to get it to connect to the database. I have used Management Studio before to retore another SQL database and the only connection I see when I open the Management Studio is the old connection to the old database. How do I connect to my new database?

View 2 RepliesIs 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 can't seem to add an Access DB to my ASP.Net project. I can see the DB in the Database Explorer Window, but I can't see any of the Tables or Views; nothing at all. I click Test Connection, and I get a message that 'Test Connection Succeeded', but I can't see anything and I don't seem to have any kind of control whatsoever. If I click on the Tables folder, I get this message: 'Attempted to read or write protected memory. This is often an indication that other memory is corrupt'. When I double-click directly on the DB, it opens and runs just fine.
The Access DB is on my desktop. Originally developed in Access 2000; using 2007 now. Also, this is VWD and ASP.Net 3.5. Any thoughts on what I'm doing wrong? It seems like a pretty easy thing, but it's turning out to be not quite as easy as I thought.
I am seriously at a loss here. The three things that will not change in this project are the fact that we are using the Entity Framework to do our data access, the fact that we want thorough unit testing and that our UI is asp.net. My question is how the hell do you make this work in Asp.net? E.g. You can use an ObjectDataSource to connect a method to a control, but if this control is a FormView you have all these problems [URL] to deal with and it simply doesn't work.
Furthermore, with grids, you don't get paging or sorting out of the box unless you use an EntityDataSource which basically circumvents your entire application. I can't be the only person who cries at this. What do you do?
in my ASP.NET applicaton I have ftpdata folder, where is MS Access 2010 somename.accdb file. On my local computer (Win XP), there is no problem to connect with OleDb to this file and read write datas into and from tables. But on server (Windows Server 2008), I cannot connect to the same file like on localhost.
View 3 RepliesI would like to connect to a password protected shared location that has an access database using an ASP page. I have the user name and password needed to connect to the shared location but I am not sure how to set up the connection string in order to get this done. The access database I would like to connect to does not need a username or password, only the shared location does.

and I'm trying to use that to submit to my database, but when I click on the submit button, no data is being inserted into my database, but I'm also not receiving any errors.
I moved to ASP.NET from PHP where the queries are run directly. So I always create Connection in the Page_Load Event, dispose it after I do all stuff needed, and access data with NpgsqlCommand. (Yes, I use Postgresql in my ASP.NET applications.)
After starting to learn ASP.NET MVC I was amazed how easy it is to access SQL with the LINQ to SQL thing. But... It works only with MS SQL. So my question is how to implement the same functionality in my applications? How to connect to databases easily?
I wrote my own wrapper classes for connecting to Postgresql. 1 class per a table.
This is a part of the Student class:
[Code]....
So as you see the problem here is that with every INSERT, DELETE, UPDATE request I'm using Connect() method which connects to the database. I didn't realize how stupid it was before I had to wait for 10 minutes to have 500 rows inserted, as there were 500 connections to the database.Using pooling while connecting does help, but still making the connection and making the server check the pool during every single query is stupid.So I decided to move Connection property to a static DB class, and it didn't work either, because it's a really bad idea to store such objects as connections in a static class.I really don't know what to do know. Yes, there's an option of manullay creating the connections in every Page_Load event and close them in the end like I'm doing it right now.

View 7 RepliesI have a system DSN.How to connect to the database in asp.net using DSN.I wanted the Connection String
View 2 Repliesso this is my first Solution using the Entity Framework (EF). Here are my steps so far:
1) Created Database named: BSA with an owner of username/password (AspNetServicesUser/password)
2) Created Entity Data Model (EDM) in a separate project (contained within the same solution)
3) Created an ASP.NET Web Application with basic functionality (new project within the same solution)
4) Added Reference to the EDM in Web App and added Connection String to the EF
5) Decided I wanted ASP.NET Membership added to the Web App
6) Configured SQL Server for Application Services using aspnet_regsql.exe on BSA database
Now, I need to know:
a) How do I create the connectionString for the Web.config file in the WebApp?
Errors I receive:
I get this error using the ASP.NET Configuration Tool under the "Security" Tab:
Login failed for user 'AspNetServicesUser'.
I get this error using the ASP.NET Configuration Tool under the "Provider" Tab --> Select a single provider for all site management data --> Test
Could not establish a connection to the database.
If you have not yet created the SQL Server database, exit the Web Site Administration tool, use the aspnet_regsql command-line utility to create and configure the database, and then return to this tool to set the provider.

I've got a situation where it seems I am required to have an identity impersonate statement in my compiled web app, i.e. <identity impersonate="true" username = "mydomainmyusername" password ="xxx" /> The thing is, it is not required when running from Visual Studio and virtual web server, as everything works fine, but when I do not have the <identity> tag in the web.config file in my compiled web app, I get a connection error. Simply won't connnect to the database if the <identity> tag is not there. I'd rather just do away with this requirement, and have been looking through IIS for a solution, but can't seem to find any.
