I have been using Access database as db of choice for a long time now and this is the first time I have run into the following error message:
Could not find file 'C:\Program Files\Common Files\Microsoft Shared\DevServer\10.0\dbo.mdb'
First, I don't have a db called dbo.mdb.
Second, the path to the db is defined in my web.config file thus:
<connectionStrings>
<add name="cingconstrng" connectionString="Provider=Microsoft.Jet.OLEDB.4.0;Data Source=c:\inetpub\wwwroot\Roster\App_Data\AllStars.mdb" providerName="System.Data.OleDb" />
</connectionStrings>
Funniest part is that I am passing the connection string to some files without problem.
So, why is it different with this file?
Is it because I am inserting records into the db with with this file?
Any ideas is greatly appreciated. I have been working on this issue since last night and googling hasn't provided any solutions.
You can see this behavior if your SQL statements use namespaces:
INSERT INTO dbo.someTable ...
Remove the namespace and it should correct the issue.

We have multiple WCF projects and we want place the all connection strings in one connectionStrings.config file and use it from there. For this I have tried the following:
connectionStrings.config file in parent folder of all WCF projects (path: D:\Projects\connectionStrings.config)
<connectionStrings>
<add name="Name"
providerName="System.Data.ProviderName"
connectionString="Valid Connection String;" />
</connectionStrings>
web.config file of each WCF Project (path: D:\Projects\SampleWCFProject\web.config)
<?xml version='1.0' encoding='utf-8'?>
<configuration>
<connectionStrings configSource="..\connectionStrings.config"/>
</configuration>
But I get this error:
The configSource attribute is invalid.: The configSource '..\connectionStrings.config' is invalid. It must refer to a file in the same directory or in a subdirectory as the configuration file.
It works if we place the connectionStrings.config in same folder as the web.config or in a child folder. But that's not what we require.
Can anyone help us with this? Thanks in advance.
In my opinion, we could refer to this file by Adding Existing Item.
Then switch the “build action” to “content” and “copy to output directory” to “Always” in the property page of the referring file.
We could choose to add a file to the current project or a link to this file.
Finally, the file in other directory cannot work may be due to problems with read and write permissions to the file.
Feel free to let me know if there is anything I can help with.
I have a passthrough connection in my c# application and I'm trying to do a select on a clob column which is in the database but not in-memory. But I get the following error, any ideas what I'm missing?
ORA-57000: TT5187: Caching LOBs from Oracle requires using an OCI client library provided by the TimesTen installation, or other versions of OCI client supported by TimesTen. -- file "bdbLob.c", lineno 224, procedure "ttBDbOraLobGetOraIdSnap"
As to Mat's comment above, I'm posting the solution for this problem. Created an entry in the config file as follows:
<oracle.dataaccess.client>
<settings>
<add name="DllPath" value="C:\oracle\bin"/>
<add name="FetchSize" value="65536"/>
<add name="PromotableTransaction" value="promotable"/>
<add name="StatementCacheSize" value="10"/>
</settings>
Dllpath is all that is needed to resolve the dll path.
I am trying to use the database send by my friend. He has created it using Sql Server Management Studio. While including the .mdf file, I am getting an error message (I have mentioned the error at the end of the answer).
I think it is because of the difference in the connection strings. I am new to .NET so I just changed the name in the connection string,
From,
<add name="ApplicationServices" connectionString="Data Source=sheroz;Initial Catalog=FLEXIFORMDB;integrated security=SSPI"/>
</connectionStrings>
To,
<add name="ApplicationServices" connectionString="Data Source=Fahad-PC\Fahad;Initial Catalog=FLEXIFORMDB;integrated security=SSPI"/>
</connectionStrings>
Please help me out to make it work. Thanks in advance.

I think you have something with your permissions. At least, this quote from your error message suggests that:
Operating system error 5: "5(Access is denied.)"
I am trying to pre-generate view metadata for my Entity Framework project and have run across a problem on the last step when using this resource:
http://msdn.microsoft.com/en-us/library/bb896240.aspx
Everything else is compiling great, but I'm getting an error when I run my application, and I suspect it's due to a problem with the final step, 're-adding mapping and model files as embedded resources for ASP.NET projects.'
I'm receiving 'Unable to load the specified metadata resource.' and my connection string is as follows:
<add name="myEntities"
connectionString="metadata=
.\DataStructure.csdl|
.\DataStructure.ssdl|
.\DataStructure.msl;provider=System.Data.SqlClient;provider
connection string="Data Source=x;Initial Catalog=x;Persist Security Info=True;User ID=x;Password=x;MultipleActiveResultSets=True""
providerName="System.Data.EntityClient" />
It is suggested in the document that my connection string file should include the following but haven't been able to get it right in any configuration:
Metadata=res://<assemblyFullName>/<resourceName>;
Metadata=res://*/<resourceName>;
Metadata=res://*;
Assuming my assembly name is DataStructure.EF, how should my string be constructed?
http://msdn.microsoft.com/en-us/library/cc716756.aspx
<connectionStrings>
<add name="AdventureWorksEntities"
connectionString="metadata=.\AdventureWorks.csdl|.\AdventureWorks.ssdl|.\AdventureWorks.msl;
provider=System.Data.SqlClient;provider connection string='Data Source=localhost;
Initial Catalog=AdventureWorks;Integrated Security=True;Connection Timeout=60;
multipleactiveresultsets=true'" providerName="System.Data.EntityClient" />

Parser Error Message: An attempt to
attach an auto-named database for file
D:\Projects\Damnation\Damnation.Website\Damnation.Website.Tracker\BugNET_WAP\App_Data\aspnetdb.mdf
failed. A database with the same name
exists, or specified file cannot be
opened, or it is located on UNC share.
Why could this be happening? My connection string doesn't use |DataDirectory|, it is:
<connectionStrings>
<add name="BugNET" connectionString="Data Source=.\SQLEXPRESS;Initial Catalog=dnmain;Integrated Security=True;"/>
</connectionStrings>
I get this error when I try to load default.aspx, after installing BugNET.
Apparently, and certainly for some obscure reason. There is a mistery connection string coming from... nowhere.
Problem solved adding a <clear/> tag.
<connectionStrings>
<clear/>
<add name="BugNET" connectionString="Data Source=.\SQLEXPRESS;Initial Catalog=dnmain;Integrated Security=True;"/>
</connectionStrings>
file
D:\Projects\Damnation\Damnation.Website\Damnation.Website.Tracker\BugNET_WAP\App_Data**aspnetdb.mdf**
failed.
This is the ASP.NET standard membership system here - not your "regular" database. There must be a second connection string somewhere that references this aspnetdb.mdf and tries to attach it from a file.
Search your solution for this file name - it must be somewhere!
