I am trying to pull some sql data to my codebehind. I think the problem is with my connection string.

And if I add Provider=SQLOLEDB; i get:
Invalid authorization specification Invalid connection string attribute
how to connect to a CSV file in ASP.net MVC?
View 1 RepliesI have a db connection string 'ApplicationServices' defined in the connectionString section of web.config and 3 Entity Framework connection strings which have the provider connection string attribute with the same connection string as the one in 'ApplicationServices'. Is there a way to reference connectionString in 'ApplicationServices' for the provider connection string attribute of the EF connection string in the web.config, rather than providing the connection string all over again?

we are facing a big problem while running our website on the production server. We decided to start using the connection pool. we added these statments to AppSettings section at the configuration file to provide the connection information to the DataAccess Layer class to access our Oracle Database.
<appSettings>
<add key="ConnectionString" value="Data Source=server;User ID=*******; Password=********; Validate Connection=true; Max Pool Size=200; Min Pool Size=10;Connection Lifetime=120; Connection Timeout=60; Incr

I have a form where users enter their preferred contact method. It has:
- a radio button where a user selects whether they'd like to be contact by phone or email or either
- a textbox for the user's email address
- a textbox for the user's phone number
I have validation via a custom attribute that verifies that if the user selected phone they entered a phone number, if they selected email they entered an email, etc... but it's at a class level on my ViewModel. As such the validation doesn't mark the expected field as invalid.
Is there a way that my IsValid override (or some other method) can mark the child property's value as invalid so I get highlighting?

View 1 RepliesI am preparing for an Access2007 db conversion at the beginning of the year and would like to know what the best process would be for connecting to the sqlserver2005 database. I have read about adding the connection string to the web.config file. I have also read about using ADO.NET and put the connection information into a class and not the web.config file.
I would like to hear from others as to what you have used, are using, or plan on using for a webapp (vs2010), and why so I can get an understanding.
I have an ASP.Net website running on IIS7. The Application Pool is set to ASPv4 Classic.
Authentication Mode is set to ASP.Net Authentication & Windows Authentication
My question is, when I want to connect to SQL using a "trusted connection" in the Connection String, what user will actually be passed into SQL?
I thought it would pass my logon details, but it is coming back with an NT AUTHORITYANONYMOUS LOGON error, which seems to point towards it not passing in my logon.
on VWD 2005 this code works fine, but on 2008 it says I haven't created an instance of the object. I want to convert the object connString (a connection string) into a string.

I'm having trouble getting a form working with MVC2. As soon as I change the form element to use 'enctype="multipart/form-data"' I get errors when submitting it. The code I've got creating the form is as follows:
[Code]....
With several form text field and a file upload being the only fields. Nothing too complicated!The action method that handles the form submission is as follows:
[Code]....
It's nothing too complicated either. The code that I've commented out would have inserted the image into the database, but I commented it out to see if it was causing the problem, but it's not.The error I'm getting is as follows:
Server Error in '/' Application.
Invalid character in a Base-64 string.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Version Information: Microsoft .NET Framework Version:2.0.50727.4927; ASP.NET Version:2.0.50727.4927
Obviously something is going terribly wrong here, but I'm at a complete loss as to what it is. The form works fine if I get rid of the multipart bit in the form element, but then of course it doesn't upload the image. I also get the error regardless of whether I've actually selected an image to upload, so it's not the actual image causing the error.

I want to have an ASP C# WebSite that loads a simple CSV File and present it in a GridView control (at least for a start).
I already have a piece of code that do almost all of the work, what i miss / unable to make it work is setting correctly the "Data Source".
The CSV file that I want to load is located on different server in the network (path is " d47vcpublicJoeASPTest").
Here is the code I wrote:

I get the following error:
'd47vcpublicJoeASPTest' is not a valid path. Make sure that the path name is spelled correctly and that you are connected to the server on which the file resides.

Problem: designer.cs is not regenerated by visual studio 2008. This concerns both web forms and master pages.
The only error or warning I can find is: Generation of designer file failed: The 'src' attribute cannot be an empty string. Line 1, Column 0
But the strangest thing is, it shows the warning always in the last page, I had or have open.
I know I'm not the only with the regeneration problem, I tried several solutions:
Deleting the *.designer.cs file. Doesn't work for me, the above warning become's an error when I try to rebuild the solutions or when try to covert to web application.
Reinstalled sp1 didn't work either.
Refresh in de designer view, getting the above warning...
Is there a solution?
