Unable To Cast COM Object Of Type 'System.__ComObject' To Class Type 'System.Data.SqlClient.SqlConn

May 17, 2006

Dear all,

I am stuck with a SSIS package and I can€™t work out. Let me know what steps are the correct in order to solve this.
At first I have just a Flat File Source and then Script Component, nothing else.

Error:





[Script Component [516]] Error: System.InvalidCastException: Unable to cast COM object of type 'System.__ComObject' to class type 'System.Data.SqlClient.SqlConnection'. Instances of types that represent COM components cannot be cast to types that do not represent COM components; however they can be cast to interfaces as long as the underlying COM component supports QueryInterface calls for the IID of the interface. at Microsoft.SqlServer.Dts.Pipeline.ScriptComponentHost.HandleUserException(Exception e) at Microsoft.SqlServer.Dts.Pipeline.ScriptComponentHost.AcquireConnections(Object transaction) at Microsoft.SqlServer.Dts.Pipeline.ManagedComponentHost.HostAcquireConnections(IDTSManagedComponentWrapper90 wrapper, Object transaction)

@PARAM1 : Unable To Cast Object Of Type 'System.Data.SqlTypes.SqlInt32 To Type System.IConvertable

Apr 23, 2007

I get the following message in the vs2005 querybuilder when i do a preview:



***********************************
SQL Execution Error.

Executed SQL statement: SELECT Schoolindex, Variant, VVSchool, [index], indincl, VVRuimtes, School FROM School WHERE (Schoolindex = @PARAM1)



Error Source: SQL Server Compact Edition ADO.NET Data Provider


Error Message: @PARAM1 : Unable to cast object of type 'System.Data.SqlTypes.SqlInt32 to type System.IConvertable'.
****************************************

The same querypreview works fine without the parameter:



SELECT Schoolindex, Variant, VVSchool, [index], indincl, VVRuimtes, School FROM School WHERE (Schoolindex = 186)



Can anybody tell me why this is?
And tell me a way to get the tableadapter working?

Nov 27, 2007



hi i dont know how to do type casting.

this.Variables.ObjVariable this objVariables i have create in variable place below like this



Name:Variable datatype int32 values 0

Name: NumberofRowsdatatype int32 values 10000

Name: ObjVariable datatype Object



My code





public override void CreateNewOutputRows()

{

/*

Add rows by calling the AddRow method on the member variable named "<Output Name>Buffer".

For example, call MyOutputBuffer.AddRow() if your output was named "MyOutput".

*/

System.Data.OleDb.OleDbDataAdapter oLead = new System.Data.OleDb.OleDbDataAdapter();

//System.Data.Odbc.OdbcDataAdapter oLead = new System.Data.Odbc.OdbcDataAdapter();

//SqlDataAdapter oLead = new SqlDataAdapter();

System.Data.DataTable dt = new System.Data.DataTable();

DataSet ds = (DataSet)this.Variables.ObjVariable; // here i am getting error

ds.Tables.Add(dt);


ADODB.Record rs = new ADODB.Record();



oLead.Fill(ds, rs, "Variables");

foreach (DataRow row in dt.Rows)

{

{

Output0Buffer.Column = (int)row["Column"];

Output0Buffer.Column1 = row["Column1"].ToString();

Output0Buffer.Column2 = row["Column2"].ToString();

}

}


}

}

This is the error

Unable To Cast Object Of Type 'System.String' To Type 'System.Web.UI.WebControls.Parameter'.

I'm getting this error on a vb.net page the needs to execute two separate stored procedures.  The first one, is the main insert, and returns the identity value for the ClientID.  The second stored procedure inserts data, but needs to insert the ClientID returned in the first stored procedure.  What am I doing wrong with including the identity value "ClientID" in the second stored procedure?

Unable To Cast Object Of Type 'System.DBNull' To Type 'System.Byte[]'.

Aug 13, 2007

Hi,
I have developed a custom server control for .NET Framework 2.0. The server control has a property named BinaryData of type byte[]. I marked this property to be data bindable. Now, I have varbinary(Max) type of field in my SQL Database and I have used SQLDataSource and bound this varbinary(Max) field with the property BinaryData (byte[]) of my control. It is working fine as long as the data value is not NULL. Now, In my control, I have handled the NULL value so that no Exception is thrown. Still, when I bind this property using the SQLDataSource, I get Error "Unable to cast object of type 'System.DBNull' to type 'System.Byte[]'." I am not sure if I can do anything to stop this erro within my control. If it is not possible from the control, then what is the workaround that I can do in my ASPX page in order to stop this error ?
Thanks a lot in advance.

System.Security.SecurityException: Request For The Permission Of Type 'System.Data.SqlClient.SqlClientPermission, System.Data

Aug 21, 2006

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.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?

System.Data.SqlClient.SqlException: The Conversion Of A Char Data Type To A Datetime Data Type Resulted In An Out-of-range Datetime Value.

Dec 14, 2005

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.

System.Data.SqlClient.SqlException: Error Converting Data Type Numeric To Decimal.

Aug 31, 2004

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.

Unable To Cast COM Object Of Type 'ADODB.CommandClass' To Interface Type 'ADODB._Command'

Dec 20, 2006

I have an application which runs successfully on a couple of my customer's machines but fails on a third. It seems to fail when opening the database:

Unable to cast COM object of type 'ADODB.CommandClass' to interface type 'ADODB._Command'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{B08400BD-F9D1-4D02-B856-71D5DBA123E9}' failed due to the following error: No such interface supported (Exception from HRESULT: 0x80004002 (E_NOINTERFACE)).
Provider=SQLOLEDB.1;Integrated Security=SSPI;Persist Security Info=false; Initial Catalog=lensdb;Data Source = SQL

Before I got this error I was getting another problem (sorry didn't make a copy of that error's text) that made me think that adodb.dll simply wasn't loaded/registered. I got rid of that error by copying my adodb.dll onto the third machine and running gacutil /i. There is now an entry in winntassemblies for adodb.

Just in case you think it could be an obvious registry problem: when I started getting the current error I thought that maybe the registry needed updating and I merged the following lines into onto the target machine (from my dev machine):

'System.Data.SqlClient.SqlClientPermission, System.Data, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' Fail

Jun 20, 2007

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 ?

Msg 6522, Level 16, State 2, Line 1: System.InvalidCastException: Conversion From Type 'SqlBoolean' To Type 'Boolean' Is Not Val

Mar 6, 2008

I created a function called Temperature in VB to be used as a UDF in SQL2005. I get the error listed below. Any thoughts?


CREATE FUNCTION Temperature(@FluidName SQL_variant, @InpCode SQL_variant, @Units SQL_variant, @Prop1 SQL_variant, @Prop2 SQL_variant)

RETURNS Float

AS EXTERNAL NAME Fluids_VB6.[Fluids_VB6.FluidProperties.Fluids].Temperature

Then ran function:


select dbo.temperature('R22','t','e','225.6','0')

Got this:


Msg 6522, Level 16, State 2, Line 1

A .NET Framework error occurred during execution of user defined routine or aggregate 'Temperature':

System.InvalidCastException: Conversion from type 'SqlBoolean' to type 'Boolean' is not valid.

System.InvalidCastException:

Cannot Convert Type 'int' To 'System.Data.DataView'

Cannot Pass Params (data Type System.guid) To Subreport?

Feb 19, 2007

Hello experts,

I am trying to create a report including a subreport in VS.2003 Reporting services. The subreport itself runs properly, if I give it a parameter, but when I try to run the main (parent) report, I get the obvious message Subreport could not be shown.

The output windows returns a message:

The value expression used in textbox €˜AccountID€™ returned a data type that is not valid.

The AccountID field is a system.guid. I tried to "cast" it as a text, but I got another error message that the system.guid cannot be explicitly converted.

Does anyone know how to get around this?

Thank you very much.

Ravie.
