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.

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.

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.

When I open up my existing SSIS project, I always get this error. Does anyone know what was wrong ?

Unable to cast COM object of type 'Microsoft.SqlServer.Dts.Runtime.Wrapper.PackageNeutralClass' to interface type 'Microsoft.SqlServer.Dts.Runtime.IObjectWithSite'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{FC4801A3-2BA9-11CF-A229-00AA003D7352}' failed due to the following error: The application called an interface that was marshalled for a different thread. (Exception from HRESULT: 0x8001010E (RPC_E_WRONG_THREAD)).
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:

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):
I have already registered the Dts.dll, but it did not make any change, also I have update the visual studio to latest update 4.I have registered the dll by using CMD to the below location and entering regsvr32 dts.dll, it brought up a popup message saying the dll the has been registered.
C:Program FilesMicrosoft SQL Server100DTSBinn
But the issue remains the same, I have to click ok on the popup msg for about 20-30 times to make it go away and the dtsx package in the solution work just fine after closing the pop up.

I found in a blog that this is caused due to a dll which is not registered ("DTS.dll")
Can anyone try to explain the exact reason for this? I am not even able to execute a package from the command prompt using the dtexec utility.

My other machine which executed this package successfully was running "Microsoft SQL Server Analysis Services Designer Version 9.00.1399.00".

I need to get the object type (view, table ...etc) for a synonym base object inside a script. The only place where I see something related to this stored is in column "base_object_name" in sys.synonyms but there I can see only the same with format [database].[user/schema].[name]. After some testing playing with different users without specifying database/schema I think that maybe the object_id must be stored in a another place, my first idea was parent_object_id in sys.synonyms but it isn't stored there.
know if object_id for the base object is stored in any other place ?

I am getting error while doing this sort of assignment.
This is a Subject Expression I put in my Mail component in my SSIS 2005 package but it's not liking the StartTime concatenation. I tried other ways but can't get it to allow this:
"Process Started by : " + @[System::UserName] + (DT_DATE) @[System::StartTime]
The data types "DT_WSTR" and "DT_DATE" are incompatible for binary operator "+". The operand types could not be implicitly cast into compatible types for the operation. To perform this operation, one or both operands need to be explicitly cast with a cast operator.
Attempt to set the result type of binary operation ""Process Started by : " + @[System::UserName] + (DT_DATE)@[System::StartTime]" failed with error code 0xC0047080.
I tried to use CAST() but not sure if that's allowed or the syntax for it specifically in SSIS 2005

when i go to http://servername/reports , the UIlogon.aspx page loads fine and i enter username and password. but i get logon failed.
when i go to http://servername/reportserver , the logon.aspx does not load and i get the following error message :

I am using an execute package task in SSIS based on the value of RUN_IND field in RUN_PARMS table. If all the value of RUN_IND field is 0 for all the files in a group, then the execute package task should be enabled else it should be disabled. So i have used the following query.
SELECT SUM(CONVERT(INT,RUN_IND)) AS RUN_IND FROM AC.RUN_PARMS WHERE [GROUP] = 'FIN'
This will return the value which will be greater than zero. Since i have made the value as 1 for FIN group. Imagine the FIN group has 10 files in it. The output look like,
RUN_IND 10
and
SELECT SUM(CONVERT(INT,RUN_IND)) AS RUN_IND FROM AC.RUN_PARMS WHERE [GROUP] = 'Ven'
This will return the value which will be equal to zero. Since i have made the value as 0 for Ven group. The output look like,
RUN_IND 0
I have created a variable in the package "user::vardisablepackage". I have set Resultset as Single for SQL task component In the package properties (The package which has to be disabled) i have selected property as "Disable" and the expression as @User::vardisablepackage = 0 ?False:True
The problem now is i am not sure what should be the data type for vardisablepackage. The expression will assign False to Disable property when the RUN_IND = 0. I am unable to complete this task since i have problem assigning data type for this variable.

I am attempting to convert an integer value to a string using the Derived Column transformation with the following expression on the field: (DT_STR,10,1252)prod_id
prod_id is an integer. I was able to do this before however, in the past couple of days, this has failed with the following error: "An error occurred while attempting to perform a type cast."
To my knowledge, I have not changed anything about this particular data flow within the past couple of days. I have verified that the value is coming in as an integer.
