Building Expression Like Properties In Custom SSIS Tasks
Oct 22, 2007
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.
Displaying Custom Properties For Custom Transformation In Custom UI
Mar 8, 2007Hi,
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#.

Expression Editor On Custom Properties On Custom Data Flow Component
Aug 14, 2007Hi,
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
DTS Old Style And Dynamic Properties Tasks
Sep 11, 2007Im using embedded SS2000 DTS packages in SSIS. These legacy packages use Dynamic Properties Tasks to pick up connection settings from a named ini file. The name of that ini file needs to change occasionally. To date the only way we have of doing this is resetting all the dynamic properties to point at the new ini file. Unfortuntely there are a lot of connections and properties and there is no budget to recreate these packages in SSIS. There must be an easier way?!
Does anyone know how to quickly change Dynamic Properties Tasks to look at a new ini?
DTS Custom Tasks
Oct 5, 2000Would anyone be aware of anyplace I could find some good information on creating DTS custom tasks? I've come across a couple of articles from SQL Server Magazine, but nothing too substantive...
Better yet, if anyone has any success (great or small), I'd like to hear from you and hear some of the things you did, what your custom task does, difficulty.
I'm just trying to get an idea of how much work I have ahead of me....
Thank You...
Upgrade Custom Tasks
Dec 4, 2007I have developed a custom task where I have a lot of properties on. Then I realized that I was missing some properties and added them to my task.
The problem is that my previous version of the task does not "upgrade" properly resulting in me needing to type in all the property values once again. I have severel task that need to upgrade but I can't figure out how to use the functions: Update, CanUpdate and Version
Any suggestion - maybe a working example?
Help much appreciated!
Non-browsable Custom Properties
Aug 16, 2006Does anyone happen to know if it is possible to set a custom data flow component property to be non-browsable? I have a number of custom component properties, and would prefer that they only be updateable through my custom UI as opposed to via the property grid on the SSIS designer,
thanks
Accessing Custom Properties In UI
May 11, 2007I am attempting to set my custom properties in the UI I have created for my custom transformation. I can access them in the ProcessInput, but if I try to assign them a new value in my UI the values dont change.
I set the properties up in ProvideComponentProperties
public override void ProvideComponentProperties()
{
// Perform component setup operations
ComponentMetaData.UsesDispositions = false;
// Add Input
IDTSInput90 input = ComponentMetaData.InputCollection.New();
input.Name = "TrimInput";
input.ErrorRowDisposition = DTSRowDisposition.RD_NotUsed;
// Add Output
IDTSOutput90 output = ComponentMetaData.OutputCollection.New();
output.Name = "TrimOutput";
output.SynchronousInputID = input.ID;
IDTSCustomProperty90 Trimproperty = ComponentMetaData.CustomPropertyCollection.New();
Trimproperty.Name = "Trim Values";
Trimproperty.Description = "Selected Trim Values";
IDTSCustomProperty90 Colproperty = ComponentMetaData.CustomPropertyCollection.New();
Colproperty.Name = "Col Names";
Colproperty.Description = "Column Names";
}
btn Click event in UI form
IDTSCustomProperty90 Trimproperty = _dtsComponentMetaData.CustomPropertyCollection["Trim Values"];
Trimproperty.Value = sConcatTrim;
IDTSCustomProperty90 Colproperty = _dtsComponentMetaData.CustomPropertyCollection["Col Names"];
Colproperty.Value = sConcatColNames;
Any suggestions or please point me to any example would be greatly appreciated.
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

Icons For Custom Tasks Won't Show Up.
Jul 31, 2006All aspects of my custom task work well except for the icon!
I have included the .ico in the assembly as an "Embedded Resource" and the icon has both 16X16 and 32X32 images. I have edited the IconResource property of the DtsTask attribute as follows:
IconResource="MyNamespace.MyDLLName.MyIconName.ico",
Where the output assembly is called "MyNamespace.MyDLLName.dll".
Has anybody got this working before? The Icon just never shows (I get the default blue square task icon).
Thanks in advance.
UDT - SQL Server 2005 - How To Add Custom Properties In C# ?
Oct 20, 2006Hello to everyone, I've a question about UDTs and the way I can use them to access tables and columns where they are applied in a SQL Server 2005 DB.
I've already spent 2 days googling and MSDN reading but nothing helped me to solve my problem, thats why I'm posting it here (this is the second post, maybe the last one was in the wrong Forum).
The scenario follows:
I've created a UDT called MyUDT that exposes 2 properties MyTable, MyColumn, here its the code:
[Serializable]
[SqlUserDefinedType(Format.UserDefined, IsByteOrdered = true, MaxByteSize = 8000, Name = "MyUDT")]
public class MyUDT : INullable, IBinarySerialize
{
private string _myTable;
private string _myColumn;
....
/// <summary>
/// Set or Get the Table Name where the UDT is applied.
/// </summary>
public string MyTable {
get { return this._myTable; }
set { this._myTable = value; }
}
/// <summary>
/// Set or Get the Table's Column Name where the UDT is applied.
/// </summary>
public string MyColumn
{
get { return this._myColumn; }
set { this._myColumn = value; }
}
....
}
And here it's my question/s:
How can I expose the defined Properties (MyTable, MyColumn) in order to be directly used from
SQL Server Management Studio within the Column Properties Panel?
Pls take a look to the print screen placed below:
[img=http://img81.imageshack.us/img81/7193/untitledip1.th.jpg]
If it is not possible, is there a way for any UDT to get back from the sql server execution context
the table and the column where it is applied/used?
I need to solve that in order to later retrieve via SQL the Extended Table Properties where the UDT is used
and make some work on presented MetaData. Thanks in advance, every answer/help will be very much appreciated.
Where To Create Custom Column Properties?
Jun 29, 2006I'm building a custom component and UI and am a bit confused on where I
need to create and/or set custom column
properties?
My UI will have a datagrid with three
columns: 1) a check box to select a column for use by the component, 2)
the input column name, and 3) a "differentiator" checkbox that indicates
an extra property about some of the columns that have the first column
checkbox checked (For example, my component may be using five input columns, but
three of those need to be used in a slightly different
way.)
The problem is, I don't understand when or
where I'm supposed to create the custom property for the input
column. SetUsageType is where I've been thinking, but I don't
know if I'm supposed to be creating it for an input column or a virtual
input column. I'd appreciate any guidance.
TransactionOption Setting And Custom SSIS Tasks - How Do You Use It?
Apr 3, 2008I can't find information on how you are suppose to handle the TransactionOption setting inside of a custom task.
I have a custom task that I have developed, and it basically calls a COM+ object that writes data to a database. When I have the task inside of a container that has the transactionoption set to required, and my custom task is set to supported, if one of the X items fail to execute in my custom task I am telling my task to fail the parent, which I thought would rollback everything. But it does not.
Is there someplace that I need to write rollback code in custom SSIS tasks? If there is I can't find any mention of it anywhere. Any examples out there on how to build custom SSIS tasks that support the TransactionOption parameter?
Thanks!

SSIS - Custom Properties For Derived And Other Transformations
May 10, 2006Hi,
I saw some thing called custom properties for the "Derived transformation" in the msdn site. I tried to use them in a simple package, but I am getting an error as "can't write to derivedoutputcolumnname.friendlyexpression". Friendly expression is one of the custom properties available for the derived transformation output columns.
The steps I followed to get to this error are as follows:
1) Get data from a table using OLEDB Source. Suppose I am getting firstName, LastName etc.
2) Derived column input is values from the above OLEDB Source.
3) I have added a new column called "Concatenated name" which is concatenated value of first and last names.
4) Then in the properties editor of this data flow task in expressions option I clicked on ellipse available. I got an editor for property expression, which contained two columns called "Property" and "Expression". Property column contains dropdown with friendly expressions propety for the derived columns and expression column is a text box, where in we can enter expression to be evaluated for the corresponding friendly expression property.
5) Now when I click on OK and try to debug it gives an error as "Can't write to concatenatedname.friendlyexpresiion".
If anybody has already faced this problem and solved it please let me know, because I am struck here a long time.
Thanks&Regards,

ADO.NET Source Custom Properties - Documentation Wrong?
Aug 16, 2005Ok, so I've looked near and far and have found nothing but info that says data flow properties can not be changed at runtime....then I see in this in the SSIS documentation under ADO.NET Source Custom Properties:

Custom Task With PropertyGrid Control SSIS - Not Able To See Properties In GUI
Apr 29, 2008Hello 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
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 Properties In External Metadata Not Writeable Using The Advanced Editor
Jun 30, 2006Hello,
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?

Calling A Custom Web Service From My Package To Perform Heavy-duty Tasks
Mar 20, 2007As part of my SSIS package, a list of sites is created that need to be created on a remote machine. let's say 1000 sites. I need to pass this list to a web service so web service sitting on that machine creates these sites for me. MY SSIS package does not run frequently so I can sacrifice time a little bit to get better functionality.
I need to move the sites that are not created (for any reasons) by web service to another table and successfully created sites to another table, so I need to get confirmation for each site from the web service.
Which option is better?
1) Calling web service for every single record (site) and get the confirmation and then based on the confirmation I move the records accordingly. I know this might be very time consuming, but as I said my SSIS package might only run every six months
OR
2) Sending records to a web service in a batch and get the result. I don€™t know how to do this though.
Any help or better solution is appreciated.

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.

Reg:- Assign File Properties To SSIS Varibales(Custom Task) In Property Grid Progrmatically.
Jul 6, 2007HI,
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.

SQL 2012 :: Connection Properties Versus SSMS Server Properties
Mar 16, 2015I have an ODBC connection string that is working fine with the following properties:
Database="XXXXXXX",Network="YYYYYY"; strangely no server is specified in the string, but it is specified in the ODBC Connection file.
I am trying to do a new server registration in SSMS for this database.However, I don't understand where the network spec is placed.
Under Registered server name I've tried:
YYYYYYXXXXX
When I browse the server for the database instance list, I receive "network path was not found".
I even tried:"XXXXXXX",Network="YYYYYY" for the registered server name.Same error message.
What am I doing wrong ?
Expression Issue With Custom Data Flow Component And Custom Property
Apr 2, 2007Hi,
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 ?

This is what I did in the custom task
