Selecting Connection In Custom Destination Component UI

Feb 24, 2006

Hi there,

I am writing a Custom Destination component with a custom UI. The UI contains a combo box which contains the connection names of type €œFLATFILE€?. I also have provided a button which would create a new connection of type €œFLATFILE€? by making a call to CreateConnection method of IDtsConnectionService.
The combo box gets properly updated showing the connections of type €œFLATFILE€? but on clicking on the new Connection button the application hangs up.
Am I missing something or is there some other way to do it?

The function are the events handlers which are called by the UI.





void form_GetConnections(object sender, AvailableColumnsArgs args)
{
Debug.Assert(this.ServiceProvider != null, "Service Provider not valid.");

this.ClearErrors();

try
{
IDtsConnectionService connectionService = (IDtsConnectionService)this.ServiceProvider.GetService(typeof(IDtsConnectionService));

if (connectionService != null)
{
ArrayList temp_Connections =
connectionService.GetConnectionsOfType("FLATFILE");

args.AvailableColumns = new AvailableColumnElement[temp_Connections.Count];
for (int i = 0; i < temp_Connections.Count; i++)
{
ConnectionManager runtimeConnection = (ConnectionManager)temp_Connections;
args.AvailableColumns.AvailableColumn = new DataFlowElement(runtimeConnection.Name, runtimeConnection);
}

}
}
catch (Exception ex)
{
this.ReportErrors(ex);
}
}

void form_GetNewConnection(object sender, AvailableColumnsArgs args)
{
Debug.Assert(this.ServiceProvider != null, "Service Provider not valid.");

this.ClearErrors();

try
{
IDtsConnectionService connectionService = (IDtsConnectionService)this.ServiceProvider.GetService(typeof(IDtsConnectionService));

if (connectionService != null)
{
connectionService.CreateConnection("FLATFILE");

ArrayList temp_Connections =
connectionService.GetConnectionsOfType("FLATFILE");

args.AvailableColumns = new AvailableColumnElement[temp_Connections.Count];
for (int i = 0; i < temp_Connections.Count; i++)
{
ConnectionManager runtimeConnection = (ConnectionManager)temp_Connections;
args.AvailableColumns.AvailableColumn = new DataFlowElement(runtimeConnection.Name, runtimeConnection);
}

}
}
catch (Exception ex)
{
this.ReportErrors(ex);
}
}

Has anyone else run into this?

I am running
SQL 2005 9.0.1399 and VS 2005 8.0.50727.42 (RTM.50727.4200) on Windows Server 2003 Enterprise Edition SP1.
Any suggestions would be welcome.

The code sample is an extension to the RemoveDuplicates sample (Dec 2005) which comes along with the SQL Server.

TIA,
Robinson

How Do I Programatically Fail My Custom Destination Component?

Nov 8, 2006

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,

~ Gary

How Do I Order Columns In My Custom Destination Component?

Nov 17, 2006

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?

Performance Issue With Custom Data Destination Component

Feb 12, 2008

Hi,
All the examples I've seen for creating custom data destinations (scripts or components) show that in the ProcessInput method you need to iterate through each record and execute a commit for each row. Here's a sample from http://forums.microsoft.com/msdn/showpost.aspx?siteid=1&postid=70469



Public Overrides Sub MyAddressInput_ProcessInputRow(ByVal Row As MyAddressInputBuffer)
With sqlCmd
.Parameters("@addressid").Value = Row.AddressID
.Parameters("@city").Value = Row.City
.ExecuteNonQuery()
End With
End Sub

This works for me but is extremely slow when processing lots of rows. Has anyone come across a better/faster example for committing rows to a database when creating a custom data destination component? I was thinking about using the ADO.NET batch update. Any thoughts on this or other approaches?

Thanks,

Mike Fulkerson

Custom Destination Component Logging - Wrote 0 Rows

Mar 17, 2006

I wrote a custom destination component. Everything works fine, except there is a logging message that is displayed that I cannot get rid of or correct. Here is the end of the output of a package containing my component:

Information: 0x40043009 at Data Flow Task, DTS.Pipeline: Cleanup phase is beginning.
Information: 0x0 at Data Flow Task, MyDestination: Inserted 40315 rows into C: empfile.txt
Information: 0x4004300B at Data Flow Task, DTS.Pipeline: "component "MyDestination" (9)" wrote 0 rows.
SSIS package "Package.dtsx" finished: Success.

I inserted a custom information message that contains the correct number of rows written by the component. I would like to either get rid of the last message "... wrote 0 rows", or figure out what to set to put the correct number of rows into that message.

This message seems to happen in the Cleanup phase. It appears whether I override the Cleanup method of the Pipeline component and do nothing, or not. Any ideas?

public override void Cleanup()

{

ComponentMetaData.FireInformation(0, ComponentMetaData.Name,

"Inserted " + m_rowCount.ToString() + " rows into " + m_fileName,

"", 0, ref m_cancel);

base.Cleanup(); // or not

}

New Custom Flat File Connection Manager Component

Jul 6, 2007



The standard flat file connection component does not handle flat files with different column counts on different rows. Since that's the type of file I have to read, I like to create a modified version of the flat file connection manager that can do this. I have found some info in how to create a connection manager. But I can't find anything that tels me how to build one that would be recognized by the flat file source dataflow component.



So how do you build an connection manager that can used by the standard flat file source component? Anyone ever did this or knows were to get the docs?





I know my problem is also solvable by reading the row into a single column and then using a script component to split them but that is not the solution I want.

A Custom Component For Use As A VIEW In SSIS- Is It Possible To Create One MERGE Like Component With More Than 2 Inputs

Aug 13, 2007

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)

Reference To Preceeding Component From Custom Dataflow Transformation Component

Mar 30, 2006

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?

Expression Editor On Custom Properties On Custom Data Flow Component

Aug 14, 2007

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

Expression Issue With Custom Data Flow Component And Custom Property

Apr 2, 2007

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 ?

I'm very confused. We even has the options of keeping or deleting the data in destination table in SQL2000 DTS package. Why we don't have this option in SQL2005??

Help With Invalid Destination Component.

I am creating and running a package programmatically. I have the source component set up fine, and the destination component seems good, but when the package is run, it gets the error message: "Excel destination failed validation and returned validation status "VS_NEEDSNEWMETADATA" ".

Hello, I am trying to create a simple package programmatically. I am following the examples in the BOL, and from some advice here. I am getting stuck at creating an Excel Destination and setting its sheetname. Everything works fine, including setting the output Excel filename.

Create A Table And Then Using It As OLE DB Destination Component

Apr 12, 2007

I want to do the following in a package:



Create a table at the beginning of a package (using a ExecuteSQLTask component) and then use the created table as a OLE DB destination component, later on the package.



Is this possible in SSIS?



The problem I run into is that I have to point the OLE DB destination component to a table and set up mappings, however as the table does not exist until the package is running, it does not seem to be possible.



I've looked at:

http://blogs.conchango.com/jamiethomson/archive/2006/11/19/SSIS_3A00_-Using-temporary-tables.aspx



Which is slightly similar to what I want, but the table I create would not be a temp tables, and I need to set up mappings and I don't see how this is possible.



Thanks

Custom Destination Adapter

Hi All,



I have built a custom flat file destination adapter but it appears that the code is not working. When I debug the process I notice that the ProcessInput section is called multiple times. The first time it looks like everything is working, then it call it again and there is no inpout from the DTSInput90.

Why would it do this?

Thanks

Write To Excel Destination Component With Specified Range

Apr 24, 2008

I have an SSIS package that produces an Excel output file say File1
The Excel output file is created from a previous script task by copying a standard excel template to File1
after the copy, File1 has the disclaimer, legend etc... and a header row at row 10.
So data rows should only start at row 11.

I was googling and found that people who read Excel file using an Excel source component have been successful reading
from a range by the use of the OPENROWSET property. It is said to set this property to Sheet1$A5-B999
to start reading from row 5.

I tried to set the OPENROWSET property to be Sheet1$A11-B999 but am getting an error "Check that object exists"
(Sheet1 does exist) So I guess it is the range that has an improper syntax or something else is wrong.

Please advise. Thanks

The Data Flow's Default Destination Component

Dec 10, 2007

Is there a default destination component used when a new data flow is created? The reason I ask is simply curiosity. I have an xml file with 2 pieces of data: item A and item B. A should simply get copied out of the file. B should undergo a quick transform. I set up an XML source such that two columns are mapped correctly to the XML source data of A and B. I set up my data transform task as well. So, if I leave those two components on the .dtsx page with no other components, then will there be a default data flow destination already created? ...OR, do you always have to have a destination component?

Thanks for the input. I am just curious.

Add A Variable From Custom Component

May 19, 2006

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

Custom Component Seems To Un-register Itself?

Apr 10, 2006

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.

Custom Source Component Problem?

Mar 23, 2006

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.

Warning: 0x80047034 at BVEIT000D_<EMPRESA> TXT, DTS.Pipeline: The DataFlow task has no components. Add components or remove the task.

Information: 0x4004300C at BVEIT000D_<EMPRESA> TXT, DTS.Pipeline: Execute phase is beginning.

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?

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?

Column Mapping In A Custom Component

Feb 7, 2006

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!

Custom Component (Transformation) Questions

May 27, 2008

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.

Custom Component And Unit Testing

Nov 11, 2007



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

column0.SetDataTypeProperties(DataType.DT_STR, 1, 0, 0, 1252);

IDTSOutputColumn90 column1 = ComponentMetaData.OutputCollection[2].OutputColumnCollection.New();
column1.Name = m_AS400ImportedDateColumnName;
column1.SetDataTypeProperties(DataType.DT_DATE, 0, 0, 0, 0);

}

Since I'm new to SSIS I'm following Josh's SSIS Xmlify Data Flow Task sample.

Thanks.

Evaluate Expression In Custom Component

Dec 12, 2007

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!

Stuck From The Start On Custom Component

Jul 4, 2006

Imports System
Imports Microsoft.SqlServer.Dts.Pipeline
Imports Microsoft.SqlServer.Dts.Pipeline.Wrapper
Imports Microsoft.SqlServer.Dts.Runtime
Imports Microsoft.SqlServer.Dts.Runtime.Wrapper

Namespace SSISComp
<DtsPipelineComponent()> _
Public Class UpperCase
Inherits PipelineComponent
End Class
End Namespace

The above is fine, i.e. at least i get no IDE complaints. But, as soon as i try to make the attribute even remotely useful, i get Mr Squiggly and he no wanna go away. (and most of this is pulled from samples so I must be missing someyhing embarrasingly obvious:

This one will get you DisplayName is not declared

Namespace SSISComp
<DtsPipelineComponent(DisplayName = "Hello")> _
Public Class UpperCase
Inherits PipelineComponent
End Class
End Namespace

This one will get you Too many argumnets to Public sub New()
Namespace SSISComp
<DtsPipelineComponent(, , , "Hello", , , , , , )> _
Public Class UpperCase
Inherits PipelineComponent
End Class
End Namespace

So, what is the syntax for this
Note, we have a reference to Microsoft.Sqlserver.Pipelinehost (as well as dtspipelinewrap,dtsruntimerap,and managedts)

Clues please
Dave
