Developing Custom Components By Extending The SSIS Stock Data Flow Components
Sep 7, 2006Everything I've read says that custom data flow components are built by inheriting from the Microsoft.SqlServer.Dts.Pipeline.PipelineComponent class.
But the stock components such as the Derived Column data flow transformation must each be implemented by their own class. So how do I base my custom components on those classes? The documentation for the PipelineComponent class doesn't list any such subclasses.
Source Code For The Standard SSIS Components That Come With SSIS?
Jun 2, 2006Hi,
I'm finding that the standard components often just don't quite meet my
needs, but would only need some fairly minor changes to save me and my team a lot of
work (and produce more elegant solutions). So I was just wondering whether the source code was available for the standard components that come with SSIS, or if there is anyway to extend their functionality?
Or do you just have to start form scratch?
Thanks,
Lawrie
Custom Components On 64-bit
Jan 22, 2008Hi again, All!!
I'm having a problem with problems with some custom components I built. I have a custom Connection Manager and Data Flow Source that I have built.
My local PC is 64-bit, but I followed the MS instructions on building and deploying custom components. They run fine inside of VS2005, as long as I have 'Run64BitRuntime" set to 'False'. When I try to run packages using the custom components in 64-bit mode, I get:
Error: 0xC0014005 at : The connection type "<MyConnectionManagerType>" specified for connection manager "PRI" is not recognized as a valid connection manager type. This error is returned when an attempt is made to create a connection manager for an unknown connection type. Check the spelling in the connection type name.
I suspect I need to either change the way I build or deploy the custom components. Can someone shed some light on this?
Thanks,
Frank
Custom SSRS Components

Thanks!
Some Ideas For Custom Tasks/components
Mar 13, 2006Hello,
I had an idea that it would be nice to be able to extend the functionality of an existing SSIS component or task by inheriting from it. Perhaps in a similar way to how it is possible to extend user controls in .Net.
e.g. The rowcount is a useful component but it would be good to create a new component that inherits from it and then override the PostExecute() method to fire an Information event containing the number of rows. That's a very simple example but I think you get the gist.
Does anyone think that would be useful? Or even made possible?
I was also wondering whether it would be possible for the SSI team to make all the icons used within SSIS available as .ico files so that we could modify them for tasks/components that might do similar things.
Thanks

How To Market Custom SSIS Components?
Oct 10, 2007
Hi,
As a hobby, I am creating custom SQL Server Integration Services components, which are installed as an add-on to out of the box components. They are mainly used to reduce the development time and minimize the maintance overhead. I would like to know, how I should market them? What are the mediums to use? Since this is the first time, I am creating a software for mass markets, I would really appreciate your help while marketing this baby.
Just FYI, the first commercially available package that I develop is for creating text based files. My package connects to any OLE DB datasource. Executes the query and stores the output in a text file. It is very useful while developing database driven custom feeds. Instead of working with multiple dataflow tasks, data flow sources, you just need to configure one single component and the rest is taken care for you. Since, the package implements the standard Microsoft Task Editor, it is very easy to learn.
Thanks for your help.

Using VB.Net For Applications And The VBA Editor From Custom Components?
Jun 30, 2006Hi,
Is it possible to make use of VB.Net for Applications and the VBA editor from your own Custom Transform Components (like the script component does)?
I would like to create a component that generates boiler-plate VBA code and that then allows developers to add their own specialised code in certain methods using the editor (just like the script component)
If so, is there any documentation anywhere on how to go about this?
Thanks in advance,
Lawrie
Is It Possible To Version Custom SSIS Components?
Jul 17, 2006Is it possible to use versioning at all with SSIS components?
My experience so far is that I have not figured out how version them at all, because if I change the version number, then apparently the <property name="UserComponentTypeName" ...> has to be changed in every single reference to the component, in every dataflow, in every single dtsx file that uses the component at all -- this will be a tremendous headache as some of this stuff is in source control. It seemsl clearly infeasible to check out and substitute and change all these references, and check them all back in, except very infrequently -- surely not feasible to do it for each small change.
I am in the habit of versioning dlls and assemblies, and actually changing at least a minor build number for each actual change, so I am a bit unhappy to find that apparently I cannot feasibly do this for a custom SSIS component :(
(I just find a dislike at apparently being forced to leave the version number invariant when I make code changes.)
What I would be very happy with, is if there were a way to adjust all the references in all the dtsx files, to refer to only the major and minor build numbers say, specifying that I am not picky about the revision numbers below those, so that it will find the latest component in the GAC matching the major and minor numbers.
That way I could still update the component version with each code change, which would make me happy, and not have to edit a zillion dtsx occurrences (not having to do that would also make me happy).
Anyone know if that is possible?
I'm hoping it is, and that it is only my ignorance at component references preventing me from doing so.
Custom HTML && Javascript OR Components
Dec 4, 2007I've been trying to find a solution to adding javascript and/or HTML to a report (not reportviewer). After a search I found that you can add javascript to a textbox under action properties and it works fine. Is there a way to add custom code anywhere on the page.
The problem is the charts that come with SRS is limited so I'd like to add my own. I'd also like to add some ajax functionality as well. I know it's possible because a company called Dundas is doing it but not exactly sure how they implemented it. We considered Dundas but they are just too expensive for the solution we need.
Any help would be much appreciated.
Using Custom Components Without Installing .dlls
Sep 7, 2007Is there a way to use a custom component programmatically (I'm using C# to create and run my packages) without installing a compiled .dll of the class into the SQL folders and the GAC? For instance, can I instantiate my custom component and somehow pass it to be used in a task in my code.
View 1 Replies View RelatedCustom Components - How To Evaluate A Property As An Expression?
Apr 11, 2008
Hi all,
I'm wondering if anyone's accomplished this before - I've been unable to find a whiff of info on how to do this so far.
I'm creating a custom component that I'd like to give a "Derived Column" type of ability to. By that, I mean I'd like to populate a property of my component with an expression (including references to input columns, package variables and functions) and be able to evaluate it at runtime - per row processed by the component.
I would also appreciate any information as to how to provide the interface to allow the user to build such an expression as well - is there a UI function in SSIS I can call to pop up the "expression builder"?
Thanks!
SSIS Performance Question For Custom Components
Nov 15, 2007
I have a SQL Server 2005 Package (32 bit, 4 processors/16 GB of RAM, 3 GB switch for SSIS) with 1 DataFlow and 5 Custom Components:
> An OLEDB Source that reads a stoed proc from Sybase
> 3 Transform Components that perform: 6-required fields check, 4-lookups (3 cached, 1 non-cached), and a calculation that is performed(called) from a .NET Library.
> A SQL Destination that uses the .NET BulkCopy Class to insert the data.
It takes about 3 hours to load 1 million records that contain 46 columns (the largest being a varchar(100)). I have tried a good number of tuning options as well as indexing/SQL techniques to improve perfromance.
Some pieces of info:
1) We dynamically create the buffer during runtime based on an SSIS variable.
2) The actions of the components are determined at runtime through config files.
We do these two things so we can have multiple data flows run through the same package for better scalability and flexibility. Since we are dynamically creating the buffer I can NOT use any of the out of the box components because of lineage and metadata inconsistency issues.
3) I noticed on PerfMon that I am spooling buffers to disk after 100K rows.
I realize this is bad, but what are my alternatives?
Should I go to 64 bit? Is there anything else I can do?
Thanks in advance,
Anthony
Creating Error Output For Custom Components
Feb 14, 2006Hi,
I have a 2 custom components - source and destination.
I want to create an error output for each, to allow the users of my component to handle errors the way they choose.
I only found a property in IDTSOuptut90 named isErrorOut - a boolean property indicating whether this output is an error output or not.
Does anyone have additional documentation / articles / code samples regarding how to really populate the rows in the error output?
Thanks
Custom Tasks/Components - Changing Version W/o Breaking Packages
May 28, 2008Whenever I make a breaking change to a custom SSIS component/tasks and update the Assembly Version, it seems to break my packages beyond repair, telling me it can't load the task:
Error loading Package1.dtsx: Error loading a task. The contact information for the task is "". This happens when loading a task fails.
All of the properties of said task now show:
Could not get value for property 'c-155-designer-name'. Specified cast is not valid.
Typically, a "breaking" change when it comes to code just means that you need to update your components to adhere to the new contract of the updated signatures. But with SSIS, it seems the only solution to this is to completely remove the component, and re-add the new version, and re-enter all of the property values/expressions. If I have a package containing 10 instances of a task that only had one property removed, for example, this results in a very time-consuming process of fixing my package.
So my questions:
1) Am I doing something wrong in my versioning/deployment that is causing my packages to unnecessarily break?
2) If this is just "by design" and the way it's meant to behave, what is the best practice for making breaking changes to custom tasks/components used by many packages? Should I just never change the assembly version, even when it is a breaking change (this seems to be less disastrous)?
3) As a last resort, if I'm stuck with having to fix the broken tasks, is there a better way to fix them rather than having to completely remove them, re-add them, and re-set all of their properties/expressions?
Thanks in advance.

Custom Data Flow Components, DllImport, And Third Party Dlls
Mar 29, 2007I've been having an issue with the integration of a third-party DLL into a custom data flow component.
The company sent me a C# project that generates a simple console application. The project includes a class that calls their DLL with DllImport. The console application runs fine.
I created a stand-alone class using the C# class they sent to expose the methods of their DLL. In my custom component, I'm referencing this class to pass data to and from their DLL.
The first method from that stand-alone class that my component encounters simply gets their installation path from the registry and does not use DllImport. That path retrieval works fine. The next method calls a function that is declared with DllImport. Each time the call fails with "System.DllNotFoundException = {"Unable to load DLL AMZip.dll': Exception from HRESULT: 0xE06D7363"}".
I've copied this DLL to countless locations (e.g., the PipelineComponents directory, the project/solution bin directory) and included these paths in all manner of path variables.
What am I missing here? Their DLL is not strong named (does this matter since I'm using DllImport?), my stand-alone class is, and of course, the custom component itself is. I appreciate the help.
Extending Source Components?
Apr 29, 2008
How can I create a source extension that reads a text file and returns a XML file? I would like to have an xml File as output, because the information is already normalized.
If I extend the class €śPipelineComponent€? I can just define IDTSExternalMetadataColumn90 as output. And I do not want to have columns. I would like to return a xml file
Is it possible to achieve this?
Number Of Source Components
Mar 14, 2008Hi All,
I want to run 13 flat file sources in one Data Flow Task, is it possible to do so? I mean I have File1, File2, File3 .....File13 as a Flat file source, Thus i want to have a transformation component for each Flat file source (File1, File2 etc), is it possible to run all these in one Data Flow Task, would you suggest your best practices? Thank you for your advice and consideration.
Example:
FlatFile1 FlatFile2 FlatFile3 FlatFile4 Etc
: : :
: : :
Derived Column1 Derived Column1 Derived Column1 Etc
: : :
: : :
OLEDB Destination1 OLEDB Destination2 OLEDB Destination3
This is to show i have 13 like this in one Data Flow Task.
Thanks
Class And Sequence Diagrams Describing SSIS Framework (for Custom Components)?

Name And Description Property Of OLEDB Source Components
Aug 24, 2006I am adding two OLE DB Source components to my pipeline and giving them different names
(via the Sourcename variable) but like they are assuming default name and description i.e. OLE DB Source which is causing the following error message on opening the package that was generated.
The package contains two objects with the duplicate name of "component "OLE DB Source" (37)" and "component "OLE DB Source" (1)"
Here is how I am doing it, in the debugger the names in both instances seem to have set correctly based on the variable but when saved they are lost. What am I doing wrong here?
IDTSComponentMetaData90 source = dataFlowTask.ComponentMetaDataCollection.New();
source.Name = Sourcename;
source.ComponentClassID = "DTSAdapter.OleDbSource.1";
source.Description = Sourcename;
Thanks
Data Conversion Components && Code Page Issue
Feb 17, 2006I am using the SSIS wizard to pull data from DB2 z/os to sql server. The data flow task that is created converts the data to DT_STR Ansi 1252 before storing to sql server database. The package is blowing up on in the data conversion component...no match in found in target code page...for my city name field.
My old dts wizard didn't have this problem. The forums seem to indicate that SSIS is no longer doing some of the implicit conversions that DTS did and I may have to do more than one conversion.
What format type/code page do I use for the other conversion? The code page for my DB2 data source is 37.
I've tried several scenarios and none of them have worked. Any hints?
Attn Microsoft : Incorrect Screenshot - SQL Server Integration Services (SSIS) Hands On Training - Creating Custom Components
Jun 25, 2006Hi All,
I am not sure if this is a correct forum to discuss on the document posted @ http://www.microsoft.com/downloads/details.aspx?familyid=1c2a7dd2-3ec3-4641-9407-a5a337bea7d3&displaylang=en on SQL Server Integration Services (SSIS) Hands on Training - Creating Custom Components.
I am assuming Microsoft Developers are constantly monitoring this forum.
In the document - SSIS Creating a Custom Transformation Component .doc on Page 2 -
Exercise 1 - Writing the no-op data flow transformation component -
Task 1 - Create a new C# Class Library Project
The textual description talks about creating a new Visual C# Class Library project in VS 2005 but the screenshot accompanying it shows the creation of new "Integration Service Project" in VS 2005.
Please change the screenshot appropriately to avoid confusions.

Using Custom Code
May 17, 2007I am trying to use custom code on a report which is:
Public Function Percentage(decValueOne As Double, decValueTwo As Double) As Object
If (decValueOne = 0 Or decValueTwo = 0) Then
Percentage = 0
Else
Percentage = (decValueOne - decValueTwo)
End If
End Function
In my textbox I have:
=Code.Percentage(SUM(Fields!PreviousYTDExpenseAmount.Value, "Template_OutputData_Sales"), SUM(Fields!PreviousYTDExpenseAmount.Value, "Template_OutputData_CGS"))
When I run the report in design mode, I get the "#Error" on that report field.
Any help with why this is happening would be greatly appreciated!
Custom Code....
Mar 21, 2007Hey guys I have a problem I am trying to solve using custom code but I am open to other solutions.
Situation: I have multiple reports that the user can see. Example (Move In Corp. report, Move In Region report,Move In Division report, Mid Year Corp. report, Mid Year Region report,Mid Year Division report etc.) I have a stored procedure that returns all the information needed based upon the UserID being passed from the report to the stored procedure.
Goal: When the user logs in I want to be able to foward the user to a specific report based upon their userid (global in RS). I currently have three textboxes(Move In, Mid Year, Year End) with navigation enabled to jump to another report. The report to which the user is passed to is determined by an expression which is something like this for the Move In text box =IIF(Fields!orgtypeid.Value = 1,"Move In Corp","Move In Region"). The orgtypeid.value is returned by the stored procedure. I want to be able to forward the user a specific Move In report (Move In Corp, Move In Region, etc) without having the user select the textbox.
Any suggestions are greatly appreciated.

SSIS Logs Vs Custom Logs Components
Feb 12, 2007Hi,
In my case I have to log the errors raised by any task in a package to either windows event log, text file or SQL server. Also I need to send an email notifications to a group of people telling them about the error.
Now can I use SSIS package logging for logging the errors into the required destinations. I mean right clicking on the package and selecting Logging, then adding the required log providers and enabling the events for logging into those. I think I have to upfront select the log providers to log the error, I will not have the liberty to log the error to the destination, the name of which is passed as a variable to the package. This is okay with me though.
Now what will a custom log provider help me to do in this case. Also can I somehow configure my package to call the send mail task everytime an error is raised.
Also, one more option can be developing a package that only does the error handling. It will take in the paramters or the error codes and descriptions, the destination to write to and a flag to send mail or not for that particular type of error.
What do you think? Kindly advise.
Thanks in advance for your help and time.

What Custom Code Can Access
Jun 8, 2007I am trying to find ways around the limitation of not being able to resize columns based on the text input. I am dynamically setting what values a column is getting from my query. I am wondering if I can access the table (and thus, the columns) from within the custom code.
For example:
Public Function Whynot() As Integer
Report.table1.TableColumn1.Width = ....
table1.TableColumn.Width = ....
Return 0
End Function
Neither of these seem to work, anyone else have any ideas?
Thanks

Custom Code Question
Feb 21, 2008I developed a ConnectionString assembly in custom code a while back. Now it won't work. I've changed boxes since. My question is do I have to have SQL Server and Reporting Services on my development machine to run Custom Code assemblies?
I put my dll in the PublicAssemblies folder. I see that I need to put my dll in C:Program FilesMicrosoft SQL Server80ToolsReport Designer but I don't have that folder.
When I try and set the ConnectionString to "=ReportingLibrary.ReportingLibraryFunctions.ConnectionString(User!UserID)", I get "Unrecognized Identifier." I checked the reference and it was still there from when the project was working before.
Code Snippet
using System;
using System.Security.Permissions;
using System.Configuration;
namespace ReportingLibrary
{
public class ReportingLibraryFunctions
{
public static string ConnectionString(string userName)
{
System.Data.SqlClient.SqlClientPermission oPerm = new System.Data.SqlClient.SqlClientPermission(PermissionState.Unrestricted);
oPerm.Assert();
string catalog;
string query;
string connectstring;
string datasrc = String.Format("Data Source={0};", ConfigurationManager.AppSettings["DataSource"]);
string userpwd = String.Format("User ID={0};Password={1};", ConfigurationManager.AppSettings["DBUsr"], ConfigurationManager.AppSettings["DBPwd"]);
query = "SELECT TOP 1 MyAcctKey FROM dbo.MyUserAcct WHERE UserName=@username;";
connectstring = String.Format("{0}Initial Catalog=MyMaster;", datasrc);
System.Data.SqlClient.SqlConnection connection = new System.Data.SqlClient.SqlConnection(String.Format("{0}{1}", datasrc, userpwd));
connection.Open();
System.Data.SqlClient.SqlCommand command = new System.Data.SqlClient.SqlCommand(query, connection);
command.Parameters.Add("@username", System.Data.SqlDbType.VarChar);
command.Parameters["@username"].Value = userName;
catalog = String.Format("MyDb_{0};", command.ExecuteScalar());
connectstring = String.Format("{0}Initial Catalog={1}", datasrc, catalog);
connection.Close();
return connectstring;
}
}

Writing A Custom Code Example
Oct 19, 2007
I have been stuck in a problem for a while now. I am trying to count the number of groups. I tried soo many things and nothing worked . Now I want to try to write a function that does the counting for me.
Can somebody write me an example of a cutom code that can be called from expression.
So my custome code should be something like that
Public int CountFun(int counter)
{
Return counter= counter +1;
}
Also how do I call this method from my expression?
i am going to call it from a field inside the groups, so each time the group is implemented i add one to the counter.
thanks
