There's a handy Visual Studio 2008 addin called MoXAML Power Toys[^] that does this.

Hello friends I have a Observable collection in my wpf window.
There is a textblock in my window which text initially should be "No Message yet" (when Observable collection is empty).
What I need to do is to set the text value of that textblock to " " when Observable collection changes (count becomes > 0)

how Can I do this.?

Any help or hints would be highly appreciated.

Thanking in Advance
Johnny

The problem you face is lack of Internet connectivty, the amounts of data in mappring are generally massive and costly to prepare by the provider. Google and Microsoft can do this for free due to economies of scale.
Yoiu will almost certainly not get anything for free, but there will be paid (and probably expensive) things you get for 3^rd party suppliers.

Hopefully someone else will have a more positive response.

Take a look at the article "GMap.NET - Great Maps for Windows Forms and Presentation"[^] here on CodeProject.
It can cache the map data, but of course you need an internet connection for filling the cache...

database connection error with sa user in SQL Express 2005

I've got 2 connection strings:

1. "Data Source=.\SQLEXPRESS;
User Id=sa;Password=hello;
AttachDbFilename=C:\inetpub\wwwroot\MySite\dbs\MyDb.mdf;
Connect Timeout=30"

2. "Data Source=.\SQLEXPRESS;
AttachDbFilename=C:\inetpub\wwwroot\MySite\dbs\MyDb.mdf;
Integrated Security=True;Connect Timeout=30;User Instance=True"

2nd is working perfectly for db connection,
but using 1st returns that error:

System.Data.SqlClient.SqlException: 
Unable to open the physical file "C:\inetpub\wwwroot\MySite\dbs\MyDb.mdf". 
Operating system error 5: "5(Access Denied)".
An attempt to attach an auto-named database for file
C:\inetpub\wwwroot\MySite\dbs\MyDb.mdf failed. 
A database with the same name exists, 
or specified file cannot be opened, 
or it is located on UNC share.

In SQL Server COnfiguration Manager I enabled all services
and protocols - SQL Server (SQLEXPRESS), SQL Server Browser,
Shared Memory, Named Pipes, TCP/IP, VIA.

In SQL Server Management Studio Express sa/hello user is present
and Server Properties->Security - SQL Server and Windows Authentication mode

If I put incorrect password in 1st connection string it reports password error.

Here is the code to connect to db and get some records just for a sake:

SqlConnection con = new SqlConnection(this.connection);
SqlDataAdapter da = new SqlDataAdapter(sql, con);
DataSet ds = new DataSet();                        
int nRows = da.Fill(ds, "Persons");

I am guessing that the Sql Server runs on a user which has no read/write access on the file specified by you in the connection string. When you use windows authentification and it works, probably you are logged on an administrator account or some other privilegiated user class.

I would start by checking the user that started the sql server (in task manager) an go check that file and all the intermmediate folders if that user has permissions.

There is no sql server exe in task manager. It is running as a service.

I've got only 1 user with admin rights on PC and logged in as him while connecting with 1st and 2nd connection strings.

For that folder I set up RW access for all users. I also added that single user and set up RW access. But still the same error.

Probably in task manager you only see your user's processes (if so there's a button to show you all the processes).
The process name is sqlserv.exe an the service usualy start's or stops this process.

To test if what I said about the access rights is true, create on the root (c:\) a folder "test", and at security settings (of the "test" folder) grant full control to everyone (and by everyone I mean the special item in the search result named "everyone"). Copy you database file there (and grant full control to the file to everyone) and change you connection string to that folder. If you first connection string will work then my asumptions were correct, if not then you have another issue.

It was NETWORK SERVICE and setting full access to it solved the problem.
Before I only enabled WRITE access, but only full access helped.

Not with the OOB gridview. You would need a third party component such as Telerik or Infragistics that has the support built in, or derive your own

Get a faster connection

Adding more threads does not guarantee increased performance, it can actually slow it do if not done properly.

To create a control that you can host in a cell in editing mode, you can implement the IDataGridViewEditingControl interface in a class derived from Control.
you can find an example in msdn named:
