Unable To Reference Dts.Runtime.Wrapper From Script Task

May 11, 2007

Hi,



I am currently trying to create a Script Task which reads in a file containing meta-data which then dynamically creates a Flat File Connection Manager and configures it using this meta data. After perusing various newsgroups and articles, it seems that I need to be able to reference the Dts.Runtime.Wrapper to do this. I have tried using the Add Reference dialog, but it does not contain a reference to this namespace. I can reference this namespace from a "Script Component" but I am unable to reference it from a "Script Task". Is this a known issue or am I just not doing something correctly? If anyone could give me any pointers it would be greatly appreciated. Thanks!

Why Do I Need Microsoft.SqlServer.Dts.Runtime.Wrapper Namespace

Jul 18, 2006

Hi,

It states pretty clearly in the documentation for the Microsoft.SqlServer.Dts.Runtime.Wrapper namespace that "This assembly is a Primary Interop Assembly (PIA) for the namespace Microsoft.SqlServer.Dts.Runtime, which is the assembly Microsoft.SqlServer.ManagedDTS (in microsoft.sqlserver.manageddts.dll). The classes in this namespace should not be instantiated. Instead, use the classes found in the Microsoft.SqlServer.Dts.Runtime. "

 

And yet as I have found out earlier today and talked about here, sometimes it is absolutely necassary to use Microsoft.SqlServer.Dts.Runtime.Wrapper. Why is this? Why is there no class in Microsoft.SqlServer.Dts.Runtime that allows me to access the specific connection managers rather than using the generic ConnectionManager class?

How To Configure A Dataflow Task Having A Runtime Source Table Name And A Runtime Destination Table Name

Apr 18, 2008

Hi,

I am having a Data flow task in For each loop which will gets 100 sourcetable names and 100 target table names...

am having a simpleData flow task which trasferes from OLEDBSource to OLEDBDestination.
I am repeating the Dataflow task which transfers from sourcetablename extracted from for loop to a destination table var.

The problem am gettting is for the first table it is able to transfer correcly because I did mapping for those tables at design time...but for the next coming sourcetable-desttable (which r having different no of cols,datatypes) its giving Validation failed...and...needs to refresh metadata....

is there any way to refresh the metadata of Data flow task (I set the property of OLEDBSource validate external meta to false then also same error is coming)

Thanks

How Do You Get A Reference To The Task Host In An SSIS Task

Feb 26, 2008

I've created my own posting for this. The original post was here, I apologize: http://forums.microsoft.com/forums/ShowPost.aspx?PostID=2906512&SiteID=1

According to the poster it's not possible. But there has to be some way to do it? Reflection (don't know how)?


I need to get a reference to the task host in an SSIS Task component.

Basically the scenario is this:

I have a custom task I have created. However I would like to validate that the ExecValueVariable is infact a string variable during the validate event of the task. I know how to verify its a string variable. But I can't figure out how to read what the user selected (such as User::Myvariable). The only way I've been able to figure out how to do it, but it only works if you open my custom task UI.

What I did is this:

I've implemented IDtsTaskUI and during the initialize section I wrote:

Sub Initialize(ByVal taskHost As TaskHost, ByVal serviceProvider As IServiceProvider) Implements IDtsTaskUI.Initialize
' Store the TaskHost of the task.
Me.taskHostValue = taskHost
Dim myTask As CustomTask= CType(taskHost.InnerObject, CustomTask)
myTask.myTaskHost = taskHost
End Sub

My Task is named: CustomTask. I have a public variable in my task as follows:

Public NotInheritable Class CustomTask
Inherits Task
Implements IDTSComponentPersist
Public myTaskHost As TaskHost = Nothing

Therefore I pass back the taskhost value to the CustomTask class, and voila I have it.

Problem is, this only works if the custom task calls the initialize method, and this only happens when you open the custom editor.

I then do the validation in my CustomTask class and it works fine, but myTaskHost is null/nothing until you actually open the custom task UI

How do I solve this?

Unable To Add Reference To Microsoft Excel In VSA

Mar 4, 2008

in an SSIS project i am building, i need to open up an excel workbook and execute a macro on that workbook. I have been unable to create the excel workbook object in my script task because i cannot seem to add a COM reference since VSA does not have this capability. in my research on the web i have seen a few solutions to this.

1. Microsoft Knowledge Base states that you can cause assemblies from other locations to be displayed in the .net list in VSA by adding other folder names under the AssemblyFolders registry key. i tried this but it had no effect and further research on the web found that nooneelse had any luck doing this either.
2. the other solution i saw is to add the needed dll to the C:WINDOWSMicrosoft.NETFrameworkv2.0.50727 directory. since i was unsure as to which dll is actually the one responsible for excel i just added all the dll's under the office11 directory in microsoft office. this too had no effect, as i still do not see the reference i need to microsoft excel in the list of available references.

this seems like this should be a fairly common problem but after several day of research and hair pulling, i have been unable to solve this. any help? anyone?

When Using A Sqldataadapter In VS 2005 I Get The Following Error At Runtime. Object Reference Not Set To An Instance Of An Object

Dec 21, 2006

Help! I have posted this before and I had hoped that the VS2005 SP1 would help my problem. It didn't. My code is shown below. I have dropped a sqlconnection, sqldataadapter and a strongly-typed dataset from the toolbox onto the component designer for my page and written my code. It compiles without any errors but at runtine I receive the system error "Object reference not set to an instance of an object."

Disabling A Task At Runtime

Oct 1, 2007

Hi all,

Here is my situation. I need to disable a task at runtime. I have a script task that configures a boolean variable at runtime and sets its value to either true or false based on a condition. And also i have already set "disable" property of the component to get value from the boolean variable. The problem here is that the component gets the default value which we give during variable creation instead of getting the configured value.

Am i missing out anything. thanks in advance.



Regards,
Praveen

SQL 2012 :: Unable To Add Service Reference In A CLR Database Project?

Apr 17, 2014

I created a CLR procedure with a service reference in Visual Studio 2010 that is being used in SQL Server 2008 R2. We recently tried to deploy it to a 2012 SQL Server, but were unable to due to compatibility issues. When I tried to upgrade the package to Visual Studio 2013 I got this error message:

Unable to cast object of type 'Microsoft.VisualStudio.Data.Tools.Package.Project.DatabaseFileNode' to type 'Microsoft.VisualStudio.Data.Tools.Package.Project.Internal.FolderNode'

I tried to create this using the 2012 Data Tools, but was unable to add a service reference with the GUI. It appears Microsoft has removed this functionality. My company has a third party app that we have limited control over, which is why we need this functionality.

Custom Task W/ Runtime User Interaction

Sep 14, 2007



I've been playing around with building custom components for SSIS. I've been doing workflow for years (using Java and Oracle). The company I worked for had a framework for publishing data that allowed for user interaction. That's something I'd love to be able to do in SSIS.

Is it possible to create a custom task that interacts with the user at runtime? So, the user starts the SSIS package. At some point, the process pops up a dialog (Windows Form) that asks the user to set a date using a calendar control.

Any thoughts?

Disable And Enable A Task At RunTime In SSIS

Apr 24, 2008



Hi,

I have a package with 3 different tasks.
Like:

1. Execute Sql Task
2. Execute Sql Task
3. Execute Sql Task
4. Execute Sql Task

ESQL1 will get max(id) from table and then based on the ID the remaining needs to be work.

Ex:
If the ID=AUS-Sdy-1
then ESQL2 will update the tbl1 and return one IDkey based on this return key the ESQL3 will
update a tbl2. ----------*( i want to disable ESQL4)
else
If the ID=AUS-Sdy-2
then ESQL3 will update the tbl1 and return one IDkey based on this return key the ESQL4 will
update a tbl2. ----------- *(i want to disable ESQL2)


Thanks

Is Task.WaitForMe Property Ignored By SSIS Runtime?

Mar 24, 2007

Can the WaitForMe Task property be used for building eventing based tasks (that is, "tasks with no defined execution lifecycle"), as Haselden's IS book terms it?

The SSIS run-time would appear to never interrogate this property.
I tried setting a breakpoint in a custom task on the WaitForMe
property. The breakpoint was never hit at run-time. Design-time only. It seems that the run-time ignores this property.


The documentation states that "On completion of any task, the runtime examines tasks that are still running in
the container, and if any of these tasks have WaitForMe set to
false, those tasks will be canceled." Well, the tasks with WaitForMe set to false are in fact not cancelled (e.g. System::CancelEvent is not signalled).


The intention of the WaitForMe Task property is to allow for event based tasks to not prevent a package (or other container) from finishing if the event never happens.

Tasks like the WMI Event Watcher, Message QueueTask set to receive, and third party tasks like file watchers, or service broker queue receivers would seem to fall in this category.

VB 2005 Express: Unable To Reference Parent And Child Columns Of A DataRelation

Dec 17, 2007

From material I have read I should be able to reference columns in a datarelation by

Parent.ColumnName
Child.ColumnName


The code below is Ok until I use the Child reference

Dim tbl0102reltn As New DataRelation("tbl012tbl02", tbl01Cols, tbl02Cols)

dataset01.Relations.Add(tbl012tbl02reltn)


'=== Add the new Forecast Column to table01 (The display table)
Dim FcstTotVol As DataColumn = New DataColumn("FcstTotVol")
'declaring a column named Name
FcstTotVol.DataType = System.Type.GetType("System.Int16")
FcstTotVol.Expression = "Child(tbl012tbl02reltn).TotVol"

The last line throws an error

"cannot interpret token Child() at position 1"

If I replace the last Line as

FcstTotVol.Expression = "tbl0102reltn.Childtable.Columns(10)"
i receive the error

"The expression contains undefined function call tbl0102reltn.Childtable.Columns()."

I am unable to find away to feed the expression required for the new column.

Can anyone assit.

Script Task DLL Reference W/o Being In GAC

Oct 25, 2006

I need to add a reference to a DLL from a script task. But I do not have the ability to put the DLL in the GAC. The DLL is a 3rd party DLL and they do not want to strong name it because that creates a chain effect having to strong name all DLL's that are used in their projects that share the DLL I need to refernce.

Ok my question is.. Can i reference that DLL somehow in the script task by manually adding the reference at runtime? I found this next snippet of code on the internet, i cant get it to work though.

Public Overridable Function CreateReferenceItem(ByVal itemName As String, ByVal assemblyName As String) As IVsaReferenceItem
Debug.Assert(Not (itemName Is Nothing) AndAlso Not (itemName = String.Empty))
Me.AssertEngineItemUnique(itemName)
Dim item As IVsaReferenceItem = CType(_engine.Items.CreateItem(itemName, VsaItemType.Reference, VsaItemFlag.None), IVsaReferenceItem)
item.AssemblyName = assemblyName
Return item
End Function

Getting A Reference To A Script Task In VB.net

Oct 6, 2006

I am trying to get a reference to a script task so I can manipulate it's properties. However I can't seem to figure it out? I have a reference to Microsoft.SqlServer.ManagedDTS and Microsoft.SqlServer.Dts.Design and based on BOL they show

Imports System

Imports System.Collections.Generic

Imports System.Text

Imports Microsoft.SqlServer.Dts.Runtime

Imports Microsoft.SqlServer.Dts.Tasks.BulkInsertTask

Imports Microsoft.SqlServer.Dts.Tasks.FileSystemTask

Imports Microsoft.SqlServer.Dts.Runtime

But I get errors saying

Imports Microsoft.SqlServer.Dts.Tasks.BulkInsertTask

Imports Microsoft.SqlServer.Dts.Tasks.FileSystemTask

can't be found? What do I need to reference or Import to be able to see the Tasks and/or Task types so I can convet InnerObject to a ScriptTask type and manipulate?

What am doing wrong?????

Dim pkgPath As String = "C:Program Files\ETLODSPolicy"Dim pkgName As String = "LoadOdsCountryCodes"

Dim pkg1 As String = pkgPath + pkgName + ".dtsx"

Dim pkg2 As String = pkgPath + pkgName + "2.dtsx"

Dim app As Application = New Application()

Dim pkg As Package = app.LoadPackage(pkg1, Nothing)

Dim x As Executable

For Each x In pkg.Executables

Dim t As TaskHost = CType(x, TaskHost)

If t.Name = "SCT Set Global Variables" Then

Dim sct As ???? = ctype(t.InnerObject,????)

End If

Can You Reference A Package Using ActiveX Script Task?

Aug 23, 2007



Using ActiveX Script Task it is possible create office automation objects such as Word and Excel typically using the CreateObject() Syntax. Can you use this syntax to create a Package object using CreateObject("DTS.Package")? If not Why not? I am not sure whether it was possible in DTS.

I am aware of the fact that ActuveX Script Task is included in this Version of SSIS and will be deprecated.

Change Self Reference Values In A Data Flow Task

May 9, 2006

Hi,

We migrate data from a legacy system to new system using SSIS. The primary key of legacy system is a user-defined sql server which holds alpha-numeric values. The primary key of new system is a big int(sequential numbers).

When we migrate data, we generate a sequential number for each legacy key(the primary key of legacy data) and insert data in to new system tables. The newly generated sequential numbers and the legacy keys are persisted in an intermidiate table for look up operations of child tables.

We are facing problem when we try to migrate tables which has self referring coulumns. For example a table called Employee has a column ManagerKey which refers to Key column of Employee table. We are struck up in defining data flow tasks to replace legacy ManagerKey column values with the new values(sequential values) generated during the migration process.

Please help me to solve this problem.

Regards,

Gopi

Is There Away To Reference Global Variables In A Lookup Transformation That Are Set Outside A Data Task Flow?

Mar 31, 2008



The logic I am trying to recreate via SSIS is the following SQL statement:

insert into db3.dbo.targettable1 -- Target database table
(SiteC,
Objecte,
Attrib1)

select distinct ?,
?,
from ? -- Source database table
join dbo.targettable2 c1 -- Target database table
on c1.Alias = ? and
c1.CSetID = ? and
c1.FacID = (select f.PFacID
from dbo.Fac f
where f.FacID = ?)
where not exists (select * from dbo.targettable2 c -- Target database table
where c.Alias = ? and
c.FacID = ? and
c.CSetID = ?)


I have an OLE DB Source that consists of an expression to approximate the following portion of the Above Select statement:

Select ?,
from ? -- Source database table and

The package has 2 global variables User:CSetID and User::FacID whose scope is global to the package and whose values are set within a Foreach Loop Container outside of the Data Flow Task

I was trying to reference the 2 global variables within the Looup Transformation to recreate the following portion of the SQL statement.but encounter errors:



join dbo.targettable2 c1 -- Target database table
on c1.Alias = ? and
c1.CSetID = ? and
c1.FacID = (select f.PFacID
from dbo.Fac f

In the Advanced Editor window of Lookup Transaction

select * from
(select * from [dbo].[targettable2 ]) as refTable
where [refTable].[Alias] = ? and [refTable].[FacID] = ? and
[refTable].[CSetID] = ?



Is there away to reference global variables in a Lookup Transformation that are set outside a Data Task Flow?

I Want To Return A String To A Wrapper From A Subordinate Stored Procedure

Sep 27, 2007

Using SQL Server 2000...I wrote a wrapper to call a sub proc (code provided below). Theintended varchar value returned in the output parameter of each procis a string implementation of an array.(The string separates elements by adding a period after each value.e.g. 1. 2. 3. 4. 5. etc., although my simplified example only createstwo elements.)My vb.net calling code parses the returned string into individualelements.I TESTED BOTH PROCS FIRST:The wrapper returns 'hello' when I test it by insertingSELECT @lString='hello'before the GO, so I believe it is called properly.The sub_proc returns the "array" I want when I call it directly.THE PROBLEM: When I call the wrapper, and expect it to call sub_proc,it returns a zero.In fact, when I assign a literal (like 'hello') to @lString insub_proc, 'hello' is not returned.So the wrapper is not calling the sub_proc, or the sub_proc is notreturning an output value.OR...I have read about some issues with OUTPUT string parameters beingtruncated or damaged somehow when passed. I doubt this is theproblem, but I'm open to anything.I want to use the wrapper because, when it's finally working, it willcall several sub_procs andreturn several output values.Any thoughts? Thanks for looking at it! - BobThe Wrapper:-----------------------------------------------------------------CREATE PROCEDURE wrapper@lString varchar(255) OUTASEXEC @lString = sub_proc @CommCode, @lString OUTGO-----------------------------------------------------------------The subordinate procedure:-----------------------------------------------------------------CREATE PROCEDURE sub_proc@lString varchar(255) OUTASDECLARE @var1 int,@var2 intSELECT @var1 =(SELECT count(mycolumn)FROM mytableWHERE condition=1)SELECT @var2 =(SELECT count(mycolumn)FROM mytableWHERE condition=2)/* If @var1 returns 5 and @var2 returns 7, Then @lString below wouldbe "5. 7." */SELECT @lString = STR(@var1) + '.' + STR(@var7) + '.'GO-----------------------------------------------------------------

Some General Questions About The Managed Plugin-Algorithmn Wrapper

Dec 31, 2007

Hi,

After I've written my first Plugin-Algorithmn, I have some general questions about the Managed Plugin-Algorithmn wrapper.

What does the Property "support" express in view of predictions? Is it the overall number of cases the found rule works for?

What's the difference between AdjustedProbability and Probability ?

There is a probability for a specific StateStatistic and one for the whole AttributeStatistic.
What does the latter one express? Perhaps the overall probability that the discovered rules will lead to correct results for this attribute ? Let's say I have two rules for an attribute. Rule A has a probability of 0.5 and Rule B has a probability of 0.66. What would be AdjustedProbability.Probability in the case? The mean of 0.5 and 0.66 ?


Best whishes,
Manfred

DTS FTP Task Unable To Connect To Internet

Jul 9, 2004

I created a DTS FTP task to connect to an FTP site. The problem I'm having is the folder I want to access you cannot see under the Files Tab. So if I put the ftp site/subdirectory in the FTP Site box, I get the error "Unable to connect to internet! Please check the source site information, your username and password"

If I go to the FTP site/subdirectory in IE all the files show up fine. I believe this is limitation of DTS, but I would like to hear from you all first.

To see what error I'm talking about:
Create a DTS FTP task
Use: ftp.microsoft.com/bussys/ with no username or password
Click the Files Tab

Normally you can just put the server name in, and see all the folders/files, but the way my FTP site is set up I cannot see the folder I want, I can only access it.

Unable To Set Variables From Script Task

Dec 29, 2006

Hi,

I have a SSIS package that copies a file from one location and puts in in another with a datetime suffix on the end. This works fine in the script task. I've then added some additional code to the script task to set a variable with this new file location. The variable value gets set in the code, as I have a messagebox displaying the value, but doesn't get set to pass to the next step.



Public Sub Main()



Dim Filename As String

Dim FileLocation As String

Filename = CStr(Dts.Variables("AgencySpendFileNameWithDateTime").Value)

FileLocation = CStr(Dts.Variables("FileLocation").Value)

FileIO.FileSystem.CopyFile(FileLocation + "AgencySpend.txt", FileLocation + Filename, True)

Dts.Variables("SendLocation").Value = CStr(FileLocation + Filename)

MsgBox(Dts.Variables("SendLocation").Value)



Dts.TaskResult = Dts.Results.Success

End Sub

SendLocation is the value I want to set for the next step. I've checked and this variables scope is at the package level.

Any suggestions?

Paul
