An invalid connection string argument has been supplied or a required connection string argument has not been supplied. The following example creates an OleDbConnection and sets some of its properties in the connection string. Odbc namespace. To maintain a high level of security, it is strongly recommended that you use the Integrated Security keyword with Persist Security Info set to false.
You can use the ConnectionString property to connect to a variety of data sources. The following example illustrates several possible connection strings.
If the Data Source keyword is not specified in the connection string, the provider will try to connect to the local server if one is available.
The ConnectionString property can be set only when the connection is closed. Many of the connection string values have corresponding read-only properties. When the connection string is set, these properties are updated, except when an error is detected.
In this case, none of the properties are updated. OleDbConnection properties return only those settings that are contained in the ConnectionString.
Resetting the ConnectionString on a closed connection resets all connection string values and related properties. This includes the password. The Initial Catalog value of the connection string corresponds to the Database property. A preliminary validation of the connection string is performed when the property is set. When an application calls the Open method, the connection string is fully validated. I'll continue right after getting an answer from him. Yes, mixed mode is on and now I have a test user.
Connection string is right and Test Connection in. It's now interesting for me whether it's possible to deny any connections somehow? Is this error due to SQL Server where some types of connections aren't allowed or smth else? I wonder how the password came into your connection string when you did not check the "Persist Security Info" box.
So, I can leave defining ProviderName in the code. BTW, it's no difference between using " around the name of the provider and not. Both ways run well. Yes, it's just a kind of typo. After making. Now, I've corrected it but no difference, the same error. Thanks for the article, it seems to be the real reason for this error.
I've added 'Network Library' option to my connection string, but have still the same error. I even tried to use server's IP address instead of its name. Oh, I see. You specified the attributes of the sqldatasource on your asp. But tell me: What is causing the error - the sqldatasource or your test procedure? They probably use completely different connection strings. You should add the "Network Library" setting to the connectin string that causes the error.
What is the connection used for? A control like gridview or just code that processes the records? One thing you also should check is whether the webserver can connect to the sql server.
Ask your admin if you can test this using a udl file on the desktop of the webserver. If this fails, it is probably a network problem, maybe caused by a firewall if the webserver sits in a DMZ.
I suppose there is some misunderstanding. I don't use it anymore. Now we talk only about my SharePoint site. The connection is used for further GridView actions. I download this page, make changes via Notepad and upload this page back to the SharePoint site main pages collection. The other part of my code is:. I have a Visual Studio and I created a simple sqlconnection graphically. From what I see there, your code should be as follows:. I've already tried SqlClient provider but with another connection string.
Now I have the same SqlException:. And he said "yes". It seems we go circle by cirlce around this problem. The next step should be testing a connection from the SharePoint server maybe using a udl file. If remote connections had been disallowed on your SQL server, you would have failed to connect via udl file from your developer PC, too. I have one proposition. I know that only those users who are the members of the particular Active Directory group can connect to this SQL Server.
If we talk about mixed mode, should the SharePoint Server be in this group too? Or specifing User ID and Password should be enough to connect to the database from anywhere? As you stated before, using inegrated security in yur connection string is not allowed, so you won't be able to us an AD user or group to access the SQL Server database from within your ASP.
Net page. The User ID and Password provided in the connection string will have to be those of a SQL Login, which can indeed be used to connect from "anywhere" unless a firewall blocks the network traffic. If that's an issue, you might talk to your sharepoint admin to change the configuration to use Windows authentication. If doing so, he might also check the impersonation setting in the web. Since I'm not a SharePoint expert, I can't tell where and how to configure it's settings. No, I haven't tried it and I'm afraid I won't be able to do it at all.
SP Admin doesn't want to cooperate. I've just tried to run the. This is the connection string to use when you have an access database protected with a password using the Set Database Password function in Access. Some reports of problems with password longer than 14 characters. Also that some characters might cause trouble.
If you are having problems, try change password to a short one with normal characters. Used to get exclusive access to the database if you, for instance, want to let the application be able to reset the database password. To specify each columns length use the Schema. See description below.
