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

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
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?
Thanks!
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)
Hi,
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,

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.
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,
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!
-Jamie
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
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.

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 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#.
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.
It's a Windows 2000 Server box with SQL 2000 on it. MSSQLSERVER &SQLSERVERAGENT services are logged in as valid domain user. I set up amail profile for that user, and can send email via Outlook 2003.However, when I go to the SQL Agent Properties in Enterprise Manager,Mail Profile is disabled.I've restarted the services & even tried rebooting the server. Thisworks on my other servers, but they're Windows 2003. Not sure ifthat's the problem though.Anybody have any clues?
View 1 Replies View RelatedI 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.

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 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();

Hello 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.
I'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.
Ok, 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:
View 15 Replies View RelatedIn 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!
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?

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.
