Hi,
Maybe I didn't search hard enough on BOL, but does Microsoft have a documented set of standards regarding custom component development for SSIS. Things like:
- extend this base class, implement this interface
- override these methods
- follow these naming conventions
- best practices
Thanks,

I have looked at everything I could find on custom components, and I'm still confused about what has to be implemented in ReinitializeMetadata. The first custom component I'm trying to build is very similar to the Audit component, a derived column synchronous transformation that should be able to create any non-empty subset of four types of output columns.
I haven't found anything that does much with the inputs, the samples all seem to rely on RemoveInvalidInputColumns. I haven't found any substantial explanation of what this method actually does, or whether there are cases it doesn't handle. If it really handles all problems on the input side I don't need to know the details, but I'd like to hear some confirmation that this is the case.
For outputs, most of the sample projects seem to just call the base method. Some projects throw out all the output columns and create new ones to match the input columns one-to-one. Project Real throws away all the output columns and external metadata columns and creates a standard set of output columns with external metadata. The RegEx sample project uses information in a component custom property to tell it what output columns to expect, then adds missing columns and deletes unwanted columns. All of these approaches are using some reference information to inform it which outputs belong and which don't. What do you do when there is no other reference, just the output column and external metadata column collections?
The description for this method is "fix the errors found in Validate", but these projects just delete everything that wasn't perfect and recreate anything missing. In cases where the number and types of output columns require some user configuration, maybe a few custom properties, it seems a little high-handed to throw it all away and make them start from scratch. Or do you assume that this method isn't called unless the component state is really screwed up? It seems to me that simply adding or deleting input and output columns in the Advanced Editor would trigger ReinitializeMetadata because the external metadata would be out of sync. If it reacted by immediately re-adding an optional default column you deleted, or deleting an unconfigured column you just added, it would be pretty annoying.
Assuming that I wanted ReinitializeMetadata to actually fix things, I have some specific questions:
1 If an output column is not mapped to an external metadata column (or mapped to a nonexistent emc), should the output column be deleted or should a matching external column be created?
2 Same question reversed, if an external column is not mapped to any output column, should it be deleted or a matching output column created?
3 Would it make sense to look for compatible unmapped output and external columns and remap them?
4 If the user adds or deletes an output column in the advanced editor, was that an output column or an external metadata column?
And another thing, is there a definative list of which methods should be marked as not cls-compliant?
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!
Having a difficult time setting up a development environment and a set of standards for SSIS package development.
First of all, you can't run the dataflow object "SQL Server Destination" in BIDS because BULKCOPY can only be run from the actual server. So how do you test/debug a package with this object in it?
Second of all, if you create an SSIS package on a developer computer in BIDS, and then import it into the SSIS package store on your development SQL server, you can't run the package from Management Studio on the developer PC. You get the error "DTS_E_PRODUCTLEVELTOLOW" when it tries to run any of the SSIS. Do I have to have SSIS installed on the developer client machine? How do I do that without installing a full server instance on each client machine (not to mention the licsense issues)?
Lastly, what protection level would you suggest using for production? We are having issues with ODBC connection passwords being decrypted and thus package steps failing in using "EncryptSensitiveWithUserKey". What exactly does this protection level do? Our network is physically very locked down, so we arent worried about SSIS package security too much, just looking for a way for them to work reliably without having to setup complicated security scenarios.
thanks for your time.
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)
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 ?
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.
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.

I am trying to write a custom ODBC driver for my application database.
I downloaded & installed the Microsoft SDK and go through the developer references APIs but I am still unable to start my driver development. Any example code from where I can take start, will be highly appreciated.
What is the minimum set of APIs which will enable my driver to allow user to execute simple SELECT statement from any ODBC client?
Which I have done till yet is a win32 dll and manually configure it with registry, due to which I can see my dll in driver listing of ODBC. I also want to know in which exe it will be load to attach process for debugging.
How much approx I should take time for its development?

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.

Hi,I have developed a custom source component to get data from a generic odbc connection with some special caracteristics.
The component works fine by getting and mapping the output fields etc...
The only two problems existing are that when i run the task it says that the data flow has no components inside... how is this possible since i have my source mapped to a flat file inside that data flow?
This is the error:
SSIS package "BVEIT000D.dtsx" starting.

SSIS package "BVEIT000D.dtsx" finished: Success.
The other problem is that if i want to <ignore> a certain source column the component already shows me an error saying that the no column with ID 0 was found...
Any one with experience in creating custom components?

Hi huys,
can you tell me how you create a MSI file for your custom component.
basically i've created a SSIS custom component, and i want to distiribute among a few people, i guess instead of providing step by step instructions it would be easy if they just clicked on packaged msi file.
i've seen many people putting their custom components on the web as MSI, how do you do it?

Does anyone know how to get destination coulmns to show up in the advanced editor for a custom component? I have a custom flat file destination component that builds the output based on a specific layout. It works as long as the upstream column names match my output names. What I want is to allow non-matching columns to be mapped by the user as they can in a stock flat file destination. The closest that I have been able to come is to get the "column mappings" tab to show up and populate the "Available Input Columns" by setting ExternalmetadataColumnCollection.IsUsed to true on the input. The problem is that the "Available destination columns" box is always empty. I have tried the IsUsed property on the output and pretty much every other property that I could find. On the Input and Output properties all of my columns show up under the output as both External and Output columns. Is there a separate collection for "destination" columns that I can't find? It's getting a little frustrating, is this something that can be done or do I have to write a custom UI to make it happen?
Thanks!

I've been trying to figure this out on my own for pretty much all of today, and part of last week. I've downloaded samples, searched this forum, blogs, etc. So I figured I would post, since it's the end of the day, and I'm not much further along.
I'm working on a custom transformation component, whose main function is to use SQL encryption/decryption to encrypt/decrypt data from the input columns, into the output columns. The component needs two strings, a key name and a certificate name, as well as the connection manager it should use to connect to SQL which will do the encryption/decryption.
Here's where I'm stuck:
1) How can I provide the key/certificate names via properties? What I'm expecting/looking for is a way to add these two properties at the component-level, which would show up under the "Custom Properties" section of the properties pane (currently, this only has one property, "UserComponentTypeName"). These key/certificate values will be used for all input columns.
2) How do I access the connection managers from within the component? What is the best way to go about using a connection manager from within my component to connect to SQL and perform the encryption/decryption? In a custom task, this was fairly simple, but it seems that same concept won't work on a transformation component.
3) Is there a better way to go about accomplishing this (column encryption via SQL from within SSIS)? Am I going about this all wrong?
As I said, I've searched for direction, but there seems to be next to nothing in the regards of a good reference for creating custom transformation components. I've looked at two MS samples, but can't seem to make any sense out of them.
Thanks in advance.

Hello.
I want to test my custom component with unit tests and i thought i must only initilize the component to play around with it. But when i calling the ProviderComponentProperties method and there the RemoveAllInputsOutputsAndCustomProperties method a NullReference exception is thrown. After debugging the test i had seen that the ComponentMetaData of the component is null. Is there a way to initilize the ComponentMetaData?
The Code of the Component looks like this:
Code Block
[DtsPipelineComponent(
DisplayName = "TestSourceAdapter",
ComponentType = ComponentType.SourceAdapter,
IconResource = "TestSourceAdapter.TestSourceAdapter.ico"
)]
public class TestSourceAdapter: PipelineComponent
{
public override void ProvideComponentProperties()
{
RemoveAllInputsOutputsAndCustomProperties();
IDTSOutput90 output = ComponentMetaData.OutputCollection.New();
output.Name = "TestSourceAdapter";
ComponentMetaData.OutputCollection
["TestSourceAdapter"].ExternalMetadataColumnCollection.IsUsed = true;
ComponentMetaData.ValidateExternalMetadata = false;
ComponentMetaData.UsesDispositions = true;
ComponentMetaData.Name = "TestSourceAdapter";
ComponentMetaData.Description = "TestSourceAdapter";
ReinitializeMetaData();
}
...
}
And in test i call only this
Code Block
TestSourceAdapter testAdapter = new TestSourceAdapter();
_testAdapter.ProvideComponentProperties();
i hope anyone can help
regards
kai

Is there a way to evaluate an expression (like the derived column component) in a custom component? If so where should I look first? Is there an example?
An extremely simple sample is to put in an expression and evaluate one column and then add that to another column to create a new column. i.e. newcolumn = column1 + column2.
I realize that the derived column allows me to do this but I'm trying to figure out if it is possible to do this in a custom component without having to build my own expression evaluator.
Thanks!

Hi all,
Is there any tutorial to learn how custom transformation component works? maybe a blog, pdf or something...

I am writing a custom dataflow destination that writes data to a named pipe server running in an external process. At runtime, in PreExecute, I check to see if the pipe exists. If it does not exist I want to be able to fail the component and gracefully complete execution of my package.
Question is, how do I do this? If I make a call to ComponentMetaData.FireError() that will only create an OnError event and not actually stop the execution. So, how to I halt the execution of my component and return the error message?
Thanks,

This is trivial I'm sure but I'll be dogged if I can find someone who mentions how to do it. I am attempting to develop a Data Flow Transformation that appends a new column (a string value) into the current stream.
I have found plenty of references on how to replace an existing column but I'd really like to just add my new column in there. It doesn't need to be configurable, it can be a static column name. I'll take a solution that allows the column name to be set at design time, don't get me wrong but the magic I'm looking for is how to implement a new column in a stream.
Yes, I am well aware of the derived column task but I will be replacing a few hundred instances and I'd much rather just drag an item onto the designer than to drag a derived column, double click it, type in the column name, set the expression and then set the datatype, etc.
Anyone spare a moment to enlighten me?

I am looking for some advice regarding saving custom component data when saving packages.
For custom "properties", this is not an issue, as saving the package will save these properties. Howver, I also have information for each column (besides the properties that columns provides, like Name and DataType) that I need to save if a package were to be saved, and right now it does not save because I am using my own objects to store the data.
I am wondering as to how I can save this information. I have looked up on serialization, but I would like to know if there is another way besides serialization to save this inforamtion as I'd rather not save this to a seperate file.
Thanks

Here is the situation. I have created a package that takes 50 columns from a comma delimited flat file. I then validate and clean the data. Next I add two columns that were not in the original source file. These two columns need to be in the 5th and 9th column position when the file is then re-written to a text file. How do i get those two columns to write out in the desired order? Any ideas?
