Hi,
Near the end of 2005 Microsoft made available some sample C# apps that implemented custom SSIS tasks and components. I think Doug Ladenshlager may have had a heavy hand in building them.
Does anyone know where they are? I can't darned well find them!

Hi all
I'm into a project which uses a lot of views for joining 2 or more tables. Using the MERGE component in SSIS will be a huge effort coz it only has 2 inputs and I gotta SORT the input too.
Isnt it possible to have a VIEW like component that joins more than 2 tables and DOESNT need sorting??
(I've thought about creating views in database engine but it breaks my data floe in SSIS and is'nt a practical solution)
In a Data Flow, I have the necessity to use a SSIS variable of type €œObject€? inside Script Component and assign to it the content of 'n' variables of string type.
On exiting from the script the variable of type object should contain something like in the following lines:
AAAAAAAAAAAAAAAAAAAAAAAAAAAAA
BBBBBBBBBBBBBBBBBBBBBBBBBBBBB
CCCCCCCCCCCCCCCCCCCCCCCCCCCCC
DDDDDDDDDDDDDDDDDDDDDDDDDDDDD
€¦€¦€¦€¦€¦€¦€¦.
€¦€¦€¦€¦€¦€¦€¦.
On exiting from the data flow I will use the variable of type Object in a Script Task, by reading each element in a cyclic fashion.
Is there anyone who have experienced something like this? Could anyone provide any example of that?
Thanks in advance!
Is there a way of disabling a custom property in a component so that during design-time the property is grayed out? I looked around the properties of IDTSCustomProperty90 and nothing sticks out.
Thanks

Does anyone here have a favorite site or set of sites with resources on SSIS custom component (tasks, transforms, log providers, etc.) development? I've been searching around to try to find this on my own, but so far I've had little luck.
Darren - I've noticed that you always seem to have the most insightful responses to questions related to SSIS .NET development (such as your recent response to evaluating expressions in a custom component) so I am particularly interested in anything that you have to share.
Thanks in advance, everyone!
How do I remove a custom component from SSIS Designer pernamently? I can easily remove it from the tool box, but I want to get rid of it completely.
I tried searching in MSDN for an answer to this question but I could not find it.
Thanks
dear experts,
i'm trying to build a package programmatically from client c# application. I'm working to create three dataflow components:
- OleDB Source
- Derived Column Transformations
- OleDb Destination.
My package works good, but i have several problems when insert an expression as Value of an IDTSCustomPropriety90 object, like this one:
[LEN](#firsname.lineageID) > 5 ? <<if true>> : <<if false>>
Simple expressions like concatenate strings, for example "#firstname.lineageID" + "#lastname.lineageID" seem to work good.
Thanks a lot in advanced.

Hi Guys,
I created a SSIS custom component, transformation (Asynchronous) with one Input collection and 2 output collections.
The SSIS Package which includes the Component I created works well in the Business Intelligence Studio, but when the same Package is run in the 'Execute Package utility' It fails to run. ( when you Double click on the dtsx file)
The cause of the failiure is
public override void PrimeOutput(int outputs, int[] outputIDs, PipelineBuffer[] buffers)
method receives only one output buffer when executed using the 'Execute Package Utility' { outputs = 1 , buffer.Length = 1 } ( when executed in the BI studio, the method receives parameters of both the output buffers that I expect { outputs = 2 , buffer.Length = 2 } )
The property ComponentMetaData.OutputCollection.Count = 2 as well. Yet the PrimeOutput method provides only 1 buffer.
The Validation Succeeds on both instances, which I assume means that Meta Data is Provided Properly.
What would be the reason for the same pakage to run in 2 different ways like this,
What might I have missed out to do, to make the package run in different ways on 'Business Intelligence Studio' and 'Execute Package Utility'
Thanks a lot
Below are some of the lines from the ProvideComonentProperties Method which deals with the output Collection, Isn't this sufficient for the PrimeOutput to provide 2 output buffers?
ProvideComponentProperties()
public override void ProvideComponentProperties()
{
RemoveAllInputsOutputsAndCustomProperties();
base.RemoveAllInputsOutputsAndCustomProperties();
base.ProvideComponentProperties();
//other function calls
IDTSOutput90 output1 = ComponentMetaData.OutputCollection[0];
output1.Name = "Output1";
output1.Description = ".......................";
extracted.SynchronousInputID =0;
IDTSOutput90 output2 = ComponentMetaData.OutputCollection.New();
output2.Name = "Output2";
output2.Description = "..........................";
output2.SynchronousInputID = 0;
//other function calls
}
Hi,
I have implemented a custom source component that can be used as the data source in the Data Flow task.
I have also created a custom UI for this component by using the IDtsComponentUI .
But my component does not have the capability of setting the custom properties via the DTS Variables using the Expression Builder.
I have looked around for samples on how to do this, but I can only find samples of how to do this for custom Control Tasks, i.e. IDtsTaskUI.
My question is, How can implement the Expression Builder in my custom Source component + custom Source UI. Or do you know of any samples which I can look at.
Thank you,
Jameel.
When I try to debug the break points will always say the source code is different from the current version, but the custom component in the GAC has the new version number. The other strange thing is the toolbox will not reset to the original version meaning it will not remove the custom components. The funny thing is after I compile the custom components and restart VS the custom component runs with the new code changes. I can see the new features I added, but the debugger and toolbox still seem to be broken.
I have tried the following
1) Reset the tool box.
2) uninstall all my custom dll from the GAC €œC:WINDOWSassembly€?
3) remove all my custom dll from €œC:Program FilesMicrosoft SQL Server90DTSPipelineComponents€?
4) restart VS 2005
5) reselect the custom components.
6) reboot my computer.
It seem like VS has another cache. For the tool box or something.
Does anybody have any suggestion?
Hi all,
I am creating a customer data flow component for SSIS for use in a package. I've got some custom properties that I am exposing using the supplied advanced editor (no custom property editor here).
Some of my properties are enumerated types, and I have deciphered how to get those properties to show as dropdown lists of their respective enumerations. (For those of you who may be looking as hard as I did as to how to accomplish this, see the end of this post.)
I also have a few properties which request SSIS package variable names - such as an file name variable. However, I can't figure out how to tell the advanced editor that the property is looking for an SSIS variable, so that it can show a dropdown list of package variables, much like virtually any other Microsoft supplied Data Flow component can.
Is there a Type Converter I could specify for those custom properties? Is there another way to instruct SSIS that my custom property is expecting a variable? Or do I need to code a custom UI for editing my Data Flow Task?
To create a dropdown list of values for a custom property that represents an enum, do the following:
1. Create your enum definition, such as "public enum ThisIsMyEnum { one, two }"
2. Create a new class that inherits from TypeConverter, such as "public class MyEnumConverter : TypeConverter"
3. Override "CanConvertFrom", and return true if "sourceType == typeof(string)"
4. Override "CanConvertTo", and return true if "destinationType == typeof(string)"
5. Override "ConvertFrom", and return the enum value (such as "one" or "two" in my example) that corresponds to the string passed in the parameter "value"
6. Override "ConvertTo", and return a string that corresponds to the enum value passed in the parameter "value"
7. Override "GetStandardValuesSupported" and return true
8. Override "GetStandarValuesExclusive" and return true to indicate that ONLY the enum values should be accepted
9. Override "GetStandardValues", and return a new StandardValuesCollection constructed with Enum.GetValues() of your enum, such as "return new StandardValuesCollection(Enum.GetValues(typeof(ThisIsMyEnum)));"
10. Just above your "public enum" declaration, add a "TypeConverter" attribute to link your type converter to your enum, such as "[TypeConverter(typeof(MyEnumConverter))]"
11. In "ProvideComponentProperties", after you've created your custom property like this: "IDTSCustomProperty90 propEnum = ComponentMetaData.CustomPropertyCollection.New()", add another line to specify the TypeConverter property of the property to the full assembly name of your type converter, like so: "propEnum.TypeConverter = typeof(MyEnumConverter).AssemblyQualifiedName;"
Hi,
I am using custom dll in script component in SSIS package. This dll is looking for some configuration settings and dsplays the message as "Configuration section could not be found in the configuration source" . Please tell me the configuration source it looks for.
Hi there,
I'm still pretty new to SSIS, what I am really battling with is getting a custom task to work.
I have developed a custom task, digitally signed it added it to the Global Assembly Cache, written the UI for it - Pretty much as it is done here: http://technet.microsoft.com/en-us/library/ms136080.aspx
but my problem is that when I drag it from the tool box into the control flow pane, I get this message: "The task user interface specified by type name 'XXXXXXXXXXXXXXXXXXX' could not be loaded.
(Microsoft.DatatransformationServices.Design).
Does anybody have an idea of what I am doing wrong here?
Duane.
I have gone through BOL and various online resources including this one and I can't find any examples on how to use custom conflict resolvers to generate a result row which is a combination of the rows to be merged.
BOL says it can be done, but suitable examples are missing. I have found various posts requesting examples from up to a year ago, but can see no replies with relevant information
In particular I would like to see examples of
1) A stored procedure based custom conflict resolver
2) A business logic handler written in VB .Net
Here's hoping

I've written several custom Control Flow and Data Flow components for SSIS. I'm trying to deploy a new Control Flow Task, however it will not show up in the "Choose Toolbox Items" window.
I have my dll's all in the right place. Because of other painful issues we have not used the GAC, and instead have put our DLL's that are referenced in the following directory: C:program filesMicrosoft SQL Server90DTSBinn. This has worked fine for other custom tasks, but not for this one.
The only things that are different about this transform are the following:
1. Not only does the task inherit from Task, it also implements two interfaces that I wrote.
2. One of the assembly references is actualy an executable instead of a dll. This is unusual, but I've done it with other .NET projects and not had any trouble.
I could move the code I need from the EXE out to a DLL. If somebody knows what could be causing this please respond?
I am writing a custom dataflow transformation component and I need to get the name of the preceeding component.
I have been trying to find a way to get a reference to the Package object, MainPipe object or IDTSPath90 object (connecting to the IDTSInput90 of my component) from my component because I think from there I can get to the information I want.
Does anyone have any suggestions?
TIA . . . Ed
Hi,
I've created a Custom Data Flow Component and added some Custom Properties.
I want the user to set the contents using an expression. I did some research and come up with the folowing:
Code Snippet
IDTSCustomProperty90 SourceTableProperty = ComponentMetaData.CustomPropertyCollection.New();
SourceTableProperty.ExpressionType = DTSCustomPropertyExpressionType.CPET_NOTIFY;
SourceTableProperty.Name = "SourceTable";
But it doesn't work, if I enter @[System:ackageName] in the field. It comes out "@[System:ackageName]" instead of the actual package name.
I'm also unable to find how I can tell the designer to show the Expression editor. I would like to see the elipses (...) next to my field.
Any help would be greatly appreciated!
Thank you
Hi,
I'm trying to enable Expression for a custom property in my custom data flow component.
Here is the code I wrote to declare the custom property:
public override void ProvideComponentProperties()
{
ComponentMetaData.RuntimeConnectionCollection.RemoveAll();
RemoveAllInputsOutputsAndCustomProperties();
IDTSCustomProperty90 prop = ComponentMetaData.CustomPropertyCollection.New();
prop.Name = "MyProperty";
prop.Description = "My property description";
prop.Value = string.Empty;
prop.ExpressionType = DTSCustomPropertyExpressionType.CPET_NOTIFY;
...
}
In design mode, I can assign an expression to my custom property, but it get evaluated in design mode and not in runtime
Here is my expression (a file name based on a date contained in a user variable):
"DB" + (DT_WSTR, 4)YEAR( @[User::varCurrentDate] ) + RIGHT( "0" + (DT_WSTR, 2)MONTH( @[User::varCurrentDate] ), 2 ) + "\" + (DT_WSTR, 4)YEAR( @[User::varCurrentDate] ) + RIGHT( "0" + (DT_WSTR, 2)MONTH( @[User::varCurrentDate] ), 2 ) + ".VER"
@[User::varCurrentDate] is a DateTime variable and is assign to 0 at design time
So the expression is evaluated as: "DB189912189912.VER".
My package contains 2 data flow.
At runtime,
The first one is responsible to set a valid date in @[User::varCurrentDate] variable. (the date is 2007-01-15)
The second one contains my custom data flow component with my custom property that was set to an expression at design time
When my component get executed, my custom property value is still "DB189912189912.VER" and I expected "DB200701200701.VER"
Any idea ?
Hi All,
I am using a Data Flow task which copies data from an Excel Source to a SQL Database Table Destination. From 15 columns I require only 10 columns to be imported to the DB Table. So I have mapped those colums. In SQL DB there is a colum called say X, whose value should be the "Remedy" for all the columns which are imported. Is there any task that can achieve it.
Please Help.
Hello All Experts,
I have created one custom task with PropertyGrid Control and two button on it. I have everything under one class library project.
Problem I am facing is when i load task and clik on Edit I can not see those properties into that GUI and even functionlity of those two buttons (OK and Cancel) not working but I am able to see those properties in default property window.
If I create this GUI as a seperate window application then I am able to see those properties in GUI and buttons also working but in SSIS I am not able to load the task.
After reading on internet about SSIS they suggest to create everything under one project which I did.
Basically I am trying to populate connection managers like Source Connection and Destination Connection when I load this task and there are much more backend functionlity but at first step i m stuck and not able to see those properties in GUI.
Please help and give your input on it. I was following "Increment Task" example given by MSDN.
If you need more info let me know.
Thanks
Hi Guys,
This is a question to the SSIS development team. I would like to know what are the requirements to implement custom SSIS Control Flow task in C++ . There is a documentation describing the process when implementing a managed task, but no such documentation exists for implementing a task in C++.
Thank you,
Ivan
1) We are writing a custome Source component for Oracle with OCI calls, Could some one please let me know how to Enable Error Handling for the Same,
2) Is it possible to write Custome Error Handeling Component for SSIS? if yes could you please help me on how to write it.
Thanks in advance.
I'm writing my first SSIS custom task. I have added Public properties, which appear in the standard task properties window, and to one of them I have added an EditorAttribute as follows:
   <Category("General"), _
   Browsable(True), _
   EditorAttribute(GetType(UIFileNameEditor), _
   GetType(System.Drawing.Design.UITypeEditor))> _
   Public Property FilesToArchive() As String
[Code] ....
When I select the FilesToArchive property in the Properties window, I get an ellipsis that appears in the property value. When I click on the ellipsis, it brings up the FolderBrowserDialog, which is defined in the UIFileNameEditor class. This all works fine.
What I want to do is to bring up the EditorUI, the one you get when you double click on the task, and also populate that with properties which can be edited. I have a class which inherits DTSBaseTaskUI, which is displayed when I double click on the task.
I can also get properties to be displayed in that UI but I cannot get them to be editable in that UI, using the same technique as in the standard Properties window, as described above.
What I want to accomplish is that at design time the designer can enter a value for some custom property on my custom task and that this value is accessed at executing time.
View 10 Replies View RelatedI am writing my first custom SSIS task and I can see that, if I put a public property into the task, I see that property in the standard Properties window. If I add a property of type String, I can put a value in that property, in the task code, and when I instantiate the task in a package, I can see the value I entered.
To try and get a drop down list property in the Properties window, I declared a property of type Combobox, and indeed a drop down list appears in that property.
My problem is trying to get values in that property. I have used the test items:

   Property.Items.Add("Jim")
But I do not see the values in the drop down list. All I do see is one item with a value of "(none)".
HI,
I need to open a File through File connection manager and want to assign these file properties to SSIS precreated varibale or Newly created varibale. I want to show file properties in Propertygrid. Properties grid will conatin File Propeties Column and SSIS varibale Combobox column. The combo box will contain New variable field. When user select New Variable field, then a new SSIS varibale window will open and we can able create New variable and that Newly created variable should add to that property comboBox.
For Instance if we create a new varibale Name "Creationdate" by clicking on New Varible in ComboBox, then that CreationDate variable should add to Property ComboBox in PropertyGrid. After adding when we select that variable Name "Creationdate" then that selected file Creation date should assign to SSIS varibale "Creationdate" field.
Any Comments or sample will help me.

I have VS 2013 installed in my machine with SQL server 2012 ,I have installed Microsoft data tools for VS 2013,In the integration service project  i used script component when i try to pen the script task its not opening VSTA projects ,its simple ideally without any action.I am facing this issue for past 2 months i tried fixing this problem but no use.
The script  task editor has "Access VSTA to write script using VS 2012".So i installed VSTA tools for 2012 and 2013 but no issue.
But the script component works for VS 2010.I have installed Microsoft Visual Studio tools for VS 2012,VS2012 AND VS 2013.
This issue is occurring for VS 2012 and VS 2013.
I have been creating SSIS packages programmatically and have run into somewhat of a dead end. I have found the examples provided with the SQL 2005 install very helpful, but they only cover setting up three tasks: Sort task, OleDB Source and a Flat File Destination.
Does anyone have any examples or knows of examples of using the Merge Join task and the Conditional Split task?
I'm doing it all programmatically and so far I'm having trouble finding much in the way of documentation or examples.
Any help would be great!
Thanks,
Mark
Am new to SSIS, I saw only few examples from the textbook but i need to learn a lot from the ssis , so can any one suggest me where can i find good examples and small projects , so that i can get more practise on the ssis.
Thanks ,

I am writing a custom task that has some custom properties. I would like to parameterize these properties i.e. read from a varaible, so I can change these variables from a config file during runtime.
I read the documentation and it says if we set the ExpressionType to CPET_NOTIFY, it should work, but it does not seem to work. Not sure if I am missing anything. Can someone please help me?
This is what I did in the custom task
customProperty.ExpressionType = DTSCustomPropertyExpressionType.CPET_NOTIFY;
In the Editor of my custom task, under custom properties section, I expected a button with 3 dots, to click & pop-up so we can specify the expression or at least so it evaluates the variables if we give @[User::VaraibleName]
Any help on this will be very much appreciated.
Thanks
Does anybody know how to generate a new identity value from within SSIS. Can anybody point me to a good example using a script component?

Hi
I am writing a custom transformation component that utilises a user variable.
Before using the variable at run time I am checking that the variable exists, but it would be nice to be able to add it if it does not. I cannot find any documentation on the subject, though I can see that the Variables class is derived from a ReadOnlyCollectionBase.
Is there a way to add a user variable with package scope from a custom component, either at run time or design time?
Thanks . . . Ed
I've run into this a second time now. I'm hoping for some resolution AND guidance for proper build, save, etc. protocols in BIDS.
I've coded a custom component, included post-build procedures to add it to the GAC, selected it from the "Choose Items..." menu, and successfully added to a data flow. I've then been able to succesfully debug it.
This was all Friday afternoon. I shut down my BIDS session(s) and called it a week. This morning when I open BIDS, I get the following error when I attempt to add it to a data flow task:
TITLE: Microsoft Visual Studio------------------------------The component could not be added to the Data Flow task.Could not initialize the component. There is a potential problem in the ProvideComponentProperties method.------------------------------ADDITIONAL INFORMATION:Error at Data Flow Task [DTS.Pipeline]: Component "component "" (16)" could not be created and returned error code 0x80131600. Make sure that the component is registered correctly.------------------------------Exception from HRESULT: 0xC0048021 (Microsoft.SqlServer.DTSPipelineWrap)------------------------------BUTTONS:OK------------------------------
What would explain this? I'm new to VS/BIDS. Am I improperly shutting down my BIDS sessions? Is a save required for my code? Does "Build <component>" not automatically save?
Also, when I re-build a component after making a change to it, what do I need to do in my package's Data Flow task? Delete the current component, re-add it, and configure it again? I'm sure there are certain things that require one type of re-initialization vs. others (i.e., making a change to the Design Time code vs. making a change to code within the ProcessInput method.)
What can I do to properly register this now? I'm dead in the water and have no idea what to do. Any help's appreciated.
