Request For The Permission Of Type 'System.Data.SqlClient.SqlClientPermission, System.Data, Version=2.0.0.0, Culture=neutral, Pu
Mar 12, 2008
I created a .net console application within which I connect to a sql server (not local) as follows,
string conn_str = "Integrated Security=SSPI;Persist Security Info=False;Initial Catalog=QuantEquitySql;Data Source=server name";
SqlConnection conn = new SqlConnection(conn_str);
conn.Open();
.
Everything works fine when I run it from my computer. When I try to run it from a network share I get the following error,
Request for the permission of type 'System.Data.SqlClient.SqlClientPermission, System.Data, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.
I am using Visual Studio 2005 and .Net framwork v2.0.50727.
Does anybody know a fix to this problem?
Thanks

I have a report that uses some embedded custom code. The embedded custom code is a function that execute some sql query on a sql server database.Everything works fine in Visual studio. The report gets deployed on the server successfully, however when running the report from report manager i get the following error message :
The Hidden expression for the table €˜table1€™ contains an error: Request for the permission of type 'System.Data.SqlClient.SqlClientPermission, System.Data, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.
Here is the code :
************************************************************************
Public function get_field() as string
Dim myConnection As System.Data.SqlClient.SqlConnection
Dim myCommand As System.Data.SqlClient.SqlCommand
Dim data_reader As System.Data.SqlClient.SqlDataReader
Dim field(100) as string
Dim i as integer
Dim j as integer
Dim sql_field as string
Dim nbr_field as integer
Dim rtn_string as string
i = 0
sql_field ="Select field from mytable"
myConnection = New System.Data.SqlClient.SqlConnection("Datasource=xxx.xxx.xxx.xxmydatabase;Initial Catalog=mydatabase;User Id=user1;Password=password1;")
myConnection.Open()
myCommand = New System.Data.SqlClient.SqlCommand(sql_field, myConnection)
data_reader = myCommand.ExecuteReader()
While data_reader.Read()
if data_reader.HasRows then
field(i)= data_reader(0).ToString()
end if
nbr_field = nbr_field + 1
i= i+1
End While
data_reader.Close()
myConnection.Close()
for j = 0 to nbr_field -1
rtn_string = rtn_string + field(j) + ","
Next j
rtn_string = left(rtn_string,rtn_string.length-1)
return rtn_string
'return sql_cmd
'return yes_no
'return lkupfield
end function
******************************************************************
Why do i get the error message ?, is this related to Code Access Security issues with .net framework. if yes
how do i set the Security so the report server or report manager allows embedded custom code to be executed. Any advice ?

I have created a windows library control that accesses a local sql database
I tried the following strings for connecting
Dim connectionString As String = "Data Source=localhostSQLEXPRESS;Initial Catalog=TimeSheet;Trusted_Connection = true"
Dim connectionString As String = "Data Source=localhostSQLEXPRESS;Initial Catalog=TimeSheet;Integrated Security=SSPI"
I am not running the webpage in a virtual directory but in
C:Inetpubwwwrootusercontrol
and I have a simple index.html that tries to read from an sql db but throws
the error
System.Security.SecurityException: Request for the permission of type 'System.Data.SqlClient.SqlClientPermission, System.Data, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.
at System.Security.CodeAccessSecurityEngine.Check(Object demand, StackCrawlMark& stackMark, Boolean isPermSet)
at System.Security.PermissionSet.Demand()
at System.Data.Common.DbConnectionOptions.DemandPermission()
at System.Data.SqlClient.SqlConnection.PermissionDemand()
at System.Data.SqlClient.SqlConnectionFactory.PermissionDemand(DbConnection outerConnection)
at System.Data.ProviderBase.DbConnectionClosed.OpenConnection(DbConnection outerConnection,
etc etc
The action that failed was:
Demand
The type of the first permission that failed was:
System.Data.SqlClient.SqlClientPermission
The Zone of the assembly that failed was:
Trusted
I looked into the .net config utility but it says unrestricted and I tried adding it to the trusted internet zones in ie options security
I think that a windows form connecting to a sql database running in a webpage should be simple
to configure what am I missing?

After testing out the application i write on the local pc. I deploy it to the webserver to test it out. I get this error.
System.Data.SqlClient.SqlException: The conversion of a char data type to a
datetime data type resulted in an out-of-range datetime value.
Notes: all pages that have this error either has a repeater or datagrid which load data when page loading.
At first I thought the problem is with the date, but then I can see
that some other pages that has datagrid ( that has a date field) work
just fine.
anyone having this problem before?? hopefully you guys can help.

Hi There,
I'm using C# to get a value for a DOUBLE precision variable, called "Length", from a textBox using the following line:
Length = Convert.ToDouble( txtLength.Text )
I'm also using the following lines to prepare my stored procedure call:
arParms[9] = new SqlParameter("@Length", SqlDbType.Decimal, 5);
arParms[9].Value = record.Length;
My stored procedure has the following parameter definition:
@Length decimal(9,3)
My problem is that if someone types a value bigger than 999999 in the textbox he will get for sure the following error:
System.Data.SqlClient.SqlException: Error converting data type numeric to decimal.
I don't know how to either make sql or C# to truncate the value or catch the exception to automatically assign 0 to the parameter.
Please Help.

Hi All,
I have a form (asp website with the default.aspx and default.aspx.cs) which I use to connect to the SQL Server 2005 database and insert, update,get and delete data to and from it. In the table I have a column called Picture to insert a photo (usually bmp files) which I declared as a varbinary(max). ID is the primary key and is an int (i tried it to be numeric & varchar).
I am trying to insert data into the table using a form with this syntax:
SqlConnection enter_conn = new SqlConnection("user id=;" +
"password=;server=servername;" +
"Trusted_Connection=yes;" +
"database=Member Profiles; " +
"connection timeout=30");
enter_conn.Open();
string insertSql = "Insert dbo.Details(ID,Last_Name,First_Name,Middle_Initial,Project, Organization,Manager,Current_Skills,Biography,Hobbies, Picture) Select 1001, 'ABC','XYZ','R',' Website Development','ACT',LKM','ASP.Net, C#.Net, SQL Server 2005, SharePoint, Java, ',' developing the new website for ACT using SharePoint and SQL Server 2005', ' Singing, Listening to Music, Dancing, Cooking, Swimming', BulkColumn from Openrowset( Bulk 'C:\photos\rose.bmp', Single_Blob) as Picture";
SqlCommand myCommand = new SqlCommand(insertSql, enter_conn);
int i = myCommand.ExecuteNonQuery();
I have no data in the table and am doing the first insert. Though the data gets inserted I am getting this exception:
System.Data.SqlClient.SqlException: Violation of PRIMARY KEY constraint 'PK_Details'. Cannot insert duplicate key in object 'dbo.Details'. The statement has been terminated. at System.Data.SqlClient.SqlConnection.OnError(SqlException exception, Boolean breakConnection) at System.Data.SqlClient.SqlInternalConnection.OnError(SqlException exception, Boolean breakConnection) at System.Data.SqlClient.TdsParser.ThrowExceptionAndWarning(TdsParserStateObject stateObj) at System.Data.SqlClient.TdsParser.Run(RunBehavior runBehavior, SqlCommand cmdHandler, SqlDataReader dataStream, BulkCopySimpleResultSet bulkCopyHandler, TdsParserStateObject stateObj) at System.Data.SqlClient.SqlCommand.RunExecuteNonQueryTds(String methodName, Boolean async) at System.Data.SqlClient.SqlCommand.InternalExecuteNonQuery(DbAsyncResult result, String methodName, Boolean sendToPipe) at System.Data.SqlClient.SqlCommand.ExecuteNonQuery() at _Default.Enter_Click(Object sender, EventArgs e) in c:Documents and SettingskrkondaXMy DocumentsVisual Studio 2005WebSitesMember ProfilesDefault.aspx.cs:line 82
Can someone please suggest anything???? I appreciate a quick response please!!!!
Thanks,
Kavya
