-----
An unhandled exception of type 'System.Data.SqlServerCe.SqlCeException' occurred in System.Data.SqlServerCe.dll
-----------

Code:

-----------------
DataSet ds=new DataSet("gr");
SqlCeConnection con=null;
SqlCeEngine Db;
string SqlCeConnString="";
-------------------------------------------
button1 click()
{
SqlCeConnString=@"\My Documents\Ace.sdf";
if(File.Exists(SqlCeConnString))
File.Delete(SqlCeConnString);
SqlCeConnString="Data Source=" + @"My Documents\Ace.sdf";
Db=new SqlCeEngine();Db.LocalConnectionString=SqlCeConnString;
Db.CreateDatabase();
} //Database created.Ok
------------------------------------------------------------
