InnerException:
what is the meaning of this? i did not get this error yesterday and getting it today. the webpage opens no problem and the text Page: 1 is definitely there.
here is a similar issue also without solution
http://bytes.com/topic/c-sharp/answers/657812-webbrowser-documenttext-getting-problem
this is a known bug and microsoft doesn't do anything about it for vs2008 at least. here's a fix:
String lastsource = ((mshtml.HTMLDocumentClass)(((webBrowser1.Document.DomDocument)))).documentElement.innerHTML;
webBrowser1.Document.OpenNew(true);
webBrowser1.Document.Write(lastsource);
now we can access DocumentText with no problems
dont forget to import mshtml as a reference
Try webBrowser1.Document.Body.InnerText.
I too found it strange that the web browser control was throwing an exception related to file access, when I was loading a page from the web.
When looking into this, I noticed something strange:
This error is far less common when the temporary internet files have recently been cleared.
I modified my application so that it clears the temporary internet files automatically when the application starts, which was enough to resolve 90% of these errors.
My code for cleaning the temporary internet files is below... I don't think this will work on all operating systems - there may be a better way - but this suits my needs because it works on Server 2008.
(my code is in vb.net, but the c# version shouldn't be too hard to figure out.)
'start cleaning the temporary internet files
Dim clearFilesProcess As Process = System.Diagnostics.Process.Start("rundll32.exe", "InetCpl.cpl,ClearMyTracksByProcess 255")
'wait for the temporary internet files to be deleted
While Not (clearFilesProcess.HasExited)
System.Threading.Thread.Sleep(200)

I am currently working on a project in which I need to use FP-Growth algorithm. I know Weka is a handy tool for it. However, I am using C# for coding (due to some other libraries I need). So, I converted weka.jar to weka.dll using IKVM.NET. Below is a code snippet that i have written:
FPGrowth FPMiner = new FPGrowth();
FPMiner.buildAssociations(dataset);
AssociationRules rules = FPMiner.getAssociationRules();
List<AssociationRule> rule = rules.getRules();
This gives me an error as:
Cannot implicitly convert type 'java.util.List' to
'System.Collections.Generic.List'.
An explicit conversion exists (are you missing a cast?)
So, I added a cast to the last line as:
List<AssociationRule> rule = (System.Collections.Generic.List<AssociationRule>)rules.getRules();
The error goes away but I get an exception when I run my code, saying:
System.InvalidCastException was unhandled Message=Unable to cast
object of type 'java.util.ArrayList' to type
System.Collections.Generic.List`1[weka.associations.AssociationRule]'.

I am answering my own question. I used this link to solve the problem I was facing. Thanks #SecretSquirrel(see the comments) and #Jon Iles (see the answer I've linked).
This is my first attempt trying to access db files from the server. If run the program locally there are no problems
I stored ms access files on the server and I trying to run the program from my laptop and I am recieving the following error....
System.Data.OleDb.OleDbException was unhandled 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.
My connection string looks something like this...
myCon = new OleDbConnection(#"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=H:\name-SERVER\SHAREDFILES\FileRDB.mdb; Jet OLEDB:System Database=system.mdw");
There has username and password for the server. Should I include this in the connection string?

I have an application that was written in VS 2005 (C#). Works fine, it calls a 3rd Party dll. Now that I've converted it to VS 2008 (using the wizard), I get the following error when trying to instantiate the 3rd party dll.
Attempted to read or write protected memory. This is often an indication that other memory is corrupt.
Not sure where to even start debugging this. Can anyone point me in the right direction?
EDIT: As a side note it does the exact same thing under VS 2010.
EDIT: Both VS 2005 and VS 2008 projects using the same code target .NET 2.0 Framework
EDIt: It's an ActiveX library called LPDFCTRLLib. I've simply added it under References and create a new instance of it:
public LPDFCTRLLib.LPDFWndClass olpdf = null;
//and later in my code
//...
//this is where it fails
olpdf = new LPDFCTRLLib.LPDFWndClass();

You should rempve the DLL and then re-Add it. Especially for an unmanaged DLL. And check with the supplier if it is compatible.
And please note: You do not convert Projects to a VS version, except maybe for the config file. You make it target a Framework version. Your question lacks all info about Fx versions.

"Anyway, the solution was to enable
JIT optimization. In other words, in
Visual Studio 2008 choose “Tools” and
then “Options”. Select “Debugging” and
“General” and find the line that says
“Suppress JIT optimization on module
load”. This kind of makes sure that
the debugger and the JIT compiled code
aren’t running out of sync because the
JIT compiler is such a super duper
optimizer of your code. This did the
trick."
I've been trying to troubleshoot a Castle ActiveRecord exception for days now. Whenever I attempt to access the database I get an exception with an InnerException value of "An attempt to attach an auto-named database for file database.mdf failed. A database with the same name exists, or specified file cannot be opened, or it is located on UNC share."
I'm trying to connect to an SQL Server Express 2005 database. I don't have any other database option because the school computers only have SQL Express on them.
My connection settings
hibernate.connection.driver_class
NHibernate.Driver.SqlClientDriver
hibernate.dialect
NHibernate.Dialect.MsSql2005Dialect
hibernate.connection.provider
NHibernate.Connection.DriverConnectionProvider
hibernate.connection.connection_string
Data Source=.\SQLExpress;Integrated Security=True;User Instance=True;AttachDBFilename=database.mdf
This fails to work even if I set AttachDBFilename to an absolute path. User Instance has no effect. The database file is currently in the root of the project mixed in with my WinForms classes.
When using
hibernate.connection.connection_string
Data Source=localhost;Initial Catalog=FinalApp;Integrated Security=True;Pooling=False
I have no problems doing this on my laptop but I can't use the SQL Server 2005 Developer Edition on the school computers.

InnerException.Message is "An attempt to attach an auto-named database for file database.mdf failed. A database with the same name exists, or specified file cannot be opened, or it is located on UNC share."
Hmmm, this is sort of a guess, but do you need to specify a database name?
(Initial Catalog in conn string)
It is probably becuase your SQL Express connection string is turning off user instance. If you leave user instance turned on then SQL will attach the database if required, if not it will just open it. If you turn it off then the attach is permenant. Any attempt to use the same connection string again will result in an error because the database already exists.
Becuase you have not attached the database by using that connection string, you will need to detach the database before you can then use the correct connection string.
I suggest you download SQL management studio express, if you haven't already got it. That will let you see the database already attached and detach it easily.
Okay, if that is not the problem can SQL server access the database file? Has it got permissions on that folder? It normally runs as network service, which you can grant access to the file just like any other user. You could eliminate the file permissions as an issue by granting full control to everyone, if that fixes it then you can tweak the permissions down to what is required. I would guess that the SQL server service account will require modify rights on the .mdf file. I don't know where it creates the .ldf for a user instance database. It might need create file rights in the same folder as the .mdf.
