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

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 ?

Hello,
Is it possible to use existing data flow components (Merge Join, aggregation,...) in a custom data flow component?
Thanks,

I implemented a custom source adaptor. I want to be able to associate custom properties with each of the output columns. I want them to be passed downsteam. The idea is to be able to retrieve these information in a downstream custom transformations of ours and process the various columns accordingly. How do I go about doing this?I noticed that the IDTSCustomProperty90 seems to have a local scope only.

Hi,
I'm having my first go at developing a destination adapter which will send data to an update Web Service.
I've got some rather big gaps in my understanding. I've been following the various samples I've found on the net and have validated my mapping and picked up all the available column names and datatypes which are appearing in the Input and Output Properties tab of the Advanced Editor but I only have a tab for "Input Columns" and not "Column Mappings".
Which method defines the availble columns for the user to map?
Let me know if I haven't given enough information.
cheers

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;"

Hello,
I'm working on a custom dataflow destination component. It makes use of the External Metadata Collection. I also use Custom Properties with the external metadata collection.
When I open the destination component using the Advanced Editor, and select an External Metadata Collection and change the Custom Property it always changes back to the original value.
Additionally the method SetExternalMetadataColumnProperty never gets called.
Here is a little Test Component that surfaces the problem:
[DtsPipelineComponent(ComponentType=ComponentType.DestinationAdapter, DisplayName="Test Destination")]
public class Class1 : PipelineComponent
{
public override void ProvideComponentProperties()
{
base.ProvideComponentProperties();
ComponentMetaData.InputCollection.RemoveAll();
IDTSInput90 input = ComponentMetaData.InputCollection.New();
input.Name = "Name";
input.ExternalMetadataColumnCollection.IsUsed = true;
IDTSExternalMetadataColumn90 ext = input.ExternalMetadataColumnCollection.New();
ext.Name = "ExtName";
IDTSCustomProperty90 customProp = ext.CustomPropertyCollection.New();
customProp.Name = "Custom Property";
customProp.Value = "Hallo";
}
public override IDTSCustomProperty90 SetExternalMetadataColumnProperty(int iID, int iExternalMetadataColumnID, string strPropertyName, object oValue)
{
return base.SetExternalMetadataColumnProperty(iID, iExternalMetadataColumnID, strPropertyName, oValue);
}
}
Any ideas how to make that work?

Hi,
I am creating a custom transformation component, and a custom user interface for that component.
In
my custom UI, I want to show the custom properties, and allow users to
edit these properties similar to how the advanced editor shows the
properties.
I know in my UI I need to create a "Property Grid".
In
the properties of this grid, I can select the object I want to display
data for, however, the only objects that appear are the objects that I
have already created within this UI, and not the actual component
object with the custom properties.
How do I go about getting the properties for my transformation component listed in this property grid?
I am writing in C#.

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.

I have a custom component that takes in unicode stream and converts it to ascii text. However I would like to make my default string length and code page editable in the standard GUI editor. Right now I can set the default to 1000 characters, but when I try to change it, it says "Property value is not valid"
Any ideas?

Ive been using SSIS for a month or two and now find I need to create some custom tasks to perform some performance logging. in the the overloaded ProviderComponentProperties section I am trying to create a property which has the same look as the Expressions properties you find elsewhere (Little + on the left and a group of sub properties when expanded).
Ive have played with creating a IDTSCustomPropertyCollection90 collection then adding my sub properties to it but I cant seem to then add my new collection to the ComponentMetaData.CustomPropertiesCollection.
Im assuming the Expressions parameter is a collection added to the properties collection but I cant figure out how. Any help would be much appreciated.

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,
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.

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.

To all the SSIS gurus,
I have a situation where I have multiple source tables, I need to populate the destination tables that have the same schema as the source ones. I dont want to do the repetitive task of creating a Dataflow for each source-destination load.
I want to create one custom dataflow component and loop through all my source tables and provide destination tables dynamically.
Is there a way to do that? Any custom data flow component out there??
Your ideas are greatly appreciated.

Hi,
I'm creating a custom data flow transformation in c#.
I would like to use expressions within this component in the same way as in the derived column component: specifying the expression as a custom property of an output column, then evaluating this expression for each row of the buffer and using this evaluated expression to populate my output column values.
So I've added an custom expression on my output column, and set its expression type to CPET_NOTIFY
IDTSCustomProperty90 exp = col.CustomPropertyCollection.New();
exp.Name = "Expression";
exp.ExpressionType = DTSCustomPropertyExpressionType.CPET_NOTIFY;
But in the ProcessInput method I don't manage to get the evaluated expressions, when I use exp.Value I get my expression definition and not its evaluation.
Is there a way to get these evaluated expressions ?
Thanks,
Stéphane

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

Hi,
I've created my own custom data flow transformation task (using C#) that
will parse a fullname and output the various name parts. In the
ProvideComponentProperties method, I create 5 output columns (prefix, first, middle,
last, and suffix). In the ProcessInput method, I parse the input and add the
name parts to the buffer. The bad thing is that I€™m making an assumption on
the position of the Full Name input column within the buffer.
I would like the €œuser€? to be able to map their "full name" input column to a known Full Name column so I don€™t have to make any assumptions. This is the first
SSIS task I€™ve tried to create and I haven€™t been able to find very many
examples online.
Any help is greatly appreciated!
Thank you,

I created a custom transform that has a custom interface and is a wizard that uses a web service. It creates custom properties and output columns on the fly. I set the dialog result to Ok and close at the end of the steps. The transform then has the custom fields and output columns I created in the wizard. I've verified this by right clicking on the transform and going to the advanced editor. If I then immediately run the package, the custom fields don't exist in the CustomPropertiesCollection. If I close the package and reopen it, the properties now are gone. If I then go through the wizard again, thus recreating the properties, they stay and don't disappear. The quickest way to get a working transform is to add it to my data flow then save, close and reopen the package and then go through the wizard. Just saving after I add the transform does not help.
Does anyone know what might be causing this very strange problem?

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

I'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.

Hi,
I developed a custom data flow task in .net 2.0 using Visual Studio 2005. I installed it into GAC using GACUTIL and also copied it into the pipeline directory. This task runs absolutely fine when I run it on my local machine both in BIDS and using the script in windows 2000 environment. However, when I deployed this package into a windows 2003 server, the package fails at the custom task level. I checked the GAC in windowsassembly directory and it is present. Also I copied the file into the PipeLine directory and verified that I copied it into the correct pipeline directory by checking the registry. The version of the assembly is still Debug. I looked up documentation in MSDN but there is very little information about the errors I am seeing.
The error I get is pasted below, Can somebody please help me as I am currently stuck and running out of ideas to fix this problem.
Code: 0xC0047067
Source: DFT Raw File DFT Raw File (DTS.Pipeline)
Description: The "component "_" (2546)" failed to cache the component metadata object and returned error code 0x80131600.

I've built a simple custom data flow transformation component following the Hands On Lab (http://www.microsoft.com/downloads/details.aspx?familyid=1C2A7DD2-3EC3-4641-9407-A5A337BEA7D3&displaylang=en) and the Books Online (ms-help://MS.MSDNQTR.v80.en/MS.MSDN.v80/MS.SQL.v2005.en/dtsref9/html/adc70cc5-f79c-4bb6-8387-f0f2cdfaad11.htm and ms-help://MS.MSDNQTR.v80.en/MS.MSDN.v80/MS.SQL.v2005.en/dtsref9/html/b694d21f-9919-402d-9192-666c6449b0b7.htm).
All it is supposed to do is create an output column and set its value to the result of calling a web service method (the transformation is synchronous). Everything seems fine, but when I run the data flow task that contains it, it doesn't generate any output. The Visual Studio debugger displays it as yellow, with 1,385 rows going into it, but the data viewer attached to its output is empty. The output metadata looks just like I expect: all of my input columns plus the new column, correctly typed. No validation or run-time warnings or errors are reported.
I'll include the entire C# file below, which only overrrides the ProvideComponentProperties, Validate, PreExecute, ProcessInput, and PostExecute methods of the parent PipelineComponent class.
Since this is effectively a specialization of the DerivedColumn transformation, could I inherit from the class that implements the DC component instead of PipelineComponent? How do I even find out what that class is?
Thanks! Here's the code:

Hi,
If I implement a custom editor by inheriting from UITypeEditor, Can I invoke it at RUN TIME from a standard control other than PropertyGrid, say a comboBox or a button ?
If it is possible, could you please let me know how to do it or could you please direct me to some URL which shows how to do it.
Do I have to create a custom control that inherits from control for doing this ?
Thank you.

Hi,
How do I retrieve the connections (connection managers) collections from Custom Data Flow destination? ComponentMetadata.RuntimeConnectionCollection is empty. I would like to be able to access all the connections defined in the package from the custom data flow task.
I came across code in which it was possible to access the Connections collection using the IDtsConnectionService for custom task (destination). The custom task has access to serviceProvider, whcih can be used to get access to the IDtsConnectionService interface but not the custom data flow task.
Any help appreciated.

Hi,
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,

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)
