I'm a web developer and I work primarily in Django -- I've never used ASP.Net or anything like that before, but I'm troubleshooting a problem for a friend's parents / client so I need some advice!
It's pretty simple: I need to change the parameters of their SQL Server database connection because of some server upgrades that happened at their hosting company -- is it ok for me to go in and just edit a .cs file, or does it need to be compiled or some other business?
Literally just need to change the parameters of
mySqlConn = new SqlConnection("server=hostname;database=dbname;uid=username;pwd=password;");
I want to know if I develop and application using entity framework 4.0 and sql server and then changing the connection string to my sql one, will it work without any problem?
What are the other considerations to keep in mind?
I 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?
Is it ok to change the config file after publishing a site? I use shared hosting. It would be nice to do things like change connection strings and smtp settings with out having to republish the site.
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.
To start, I am a new web developer. I have been writing C# for about a year, but just recently learning web development. I wrote an application that connects to a MySql database and when I run it on my localhost it wokrs great! I created a ubuntu server on amazon ec2 and it is hosting my MySql server. It is up and running just fine. I created a windows 2008 server instance on amazon ec2 to host my asp.net project. I published my project to my windows server and I went to my public IP address and my site was there! it was so easy...
However, when I went to login, I recieved this error: Could not load file or assembly 'MySql.Data, Version=6.3.5.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d' or one of its dependencies. The system cannot find the file specified. I made sure the correct connector was installed on ym server. I have the most recent mysql connector installed. I do not know how the publish actually works. I saw some forum posts that said maybe I was missing DLLs from my bin directory but I cannot even find my bin directory for my project on the server. I also saw some posts about changing the web config file, but that was gibberish to me at this level.
I 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.
'This acceses the virtual directory web.config file for connection strings 'We have to convert the object to a connection string Dim rootWebConfig As System.Configuration.Configuration rootWebConfig = System.Web.Configuration.WebConfigurationManager.OpenWebConfiguration("/VirtualDirec") Dim connString As System.Configuration.ConnectionStringSettings connString = rootWebConfig.ConnectionStrings.ConnectionStrings("ConnectString1") Dim strConnString As String = connString.ToString().......
From the last few days I am struggling with the error
"Failed to generate a user instance of SQL Server due to failure in retrieving the user's local application data path. Please make sure the user has a local user profile on the computer. The connection will be closed." I hav created an asp.net web application with membership shcema. It works fine an my developement machine but when I published it on my web server.
I have some problem to understand how this example works with the updatepanel. I have put a ListBox4 and a label inside an updatepanel and put the property for the ListBox to AutoPostBack = true; So what I now am trying to do is when I click on the four items in the ListBox, I want the label to update the new String that is clicked in the ListBox. However what first happens when I click the 2:nd item is that I get the error:
Index was out of range. Must be non-negative and less than the size of the collection. I wonder what the correct way is to do this. I am not sure to know what is right here ? I think many example I do will be solved if I learn this one.
In order to pull a connection string from (a method, a web service, or what ever) just not the web.config.To return a connection string not from the web.config?
I know we can make the connection string of a table adapter public and change it when we access the table. I want one place (the ConfigurationManager.ConnectionStrings) change to pull the connection string from another method, just not the web.config. I do not keep connection strings in the web.config and would like to override this method.
Been doing web pages for years using html code and css. Recently decided to try asp.net and love it, probably because I'm an old C, C++ programmer. Every time I do a project the need for a database seems to come up which I've had no luck in setting up. So far I've worked around the need for a database by using text tiles in the App_Data folder. But this time I need a bunch of different text files or one text file and a lot of code finding the right entry. In short I believe a database would really fit here.
Can someone give me a "step by step" on accessing a database. I have an ip address my web host says I'll need. I believe the key is writing the connection string. I've been to connectionstrings.com and was unable to interpret anything there into what I need.
