Custom Task With PropertyGrid Control SSIS - Not Able To See Properties In GUI
Apr 29, 2008
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,
Had anyone code a custom task UI and used the propertygrid like most of the SSIS components do?
I am having an issue while trying to get the connections from my UI FORM.
They way i did was to get the parent of the form (The package) and then get the connections but that will only work for the FORM if i use the property from the properties panel i throws an error because obviously i dont have the FORM neither the parent...
I now i should use the service provider and get the IDTSconnection... but somehow it always comes = "Nothing"....
Regards

Hi Guys,
This is a question to the SSIS development team. I would like to know what are the requirements to implement custom SSIS Control Flow task in C++ . There is a documentation describing the process when implementing a managed task, but no such documentation exists for implementing a task in C++.
Thank you,
Ivan

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.

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 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,
Sreekanth Ammisetty

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

A common issue that I run across with clients is they want only want to process a file if it's finished transmitting to the server. This SQL Server 2005 task reads the properties of a file and writes the values to a series of variables. For example, you can use this task to determine if the file is in use (still be uploaded or written to) and then conditionally run the Data Flow task to load the file if it's not being used. You can also use it to determine when the file was created in order to determine if it must be archived.

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.

Hi All,
I am working on a SSIS package which is using a Script task, now I have all the connection properties set up in the .NET script using connection strings, what do I need to do if I have to set this up using a config file or something else which is more secure (I dont want to leave the connection information in the script). Please Advice.

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#.

I am trying to read in a flat file, transform the fields and store into a destination database.
In DTS, this works using Transform Data Task Properties. I define the columns and then have a VB script on the Transformations tab that changes any bad data.
Is there a way to do this in SSIS that I can define the column transformations and re-use my VB scripts?

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

If, in an SSIS package, you put an instance of an 'Execute SQL Task' task in the Control Flow, in the Properties window, you can see the properties of the task, for example CodePage.
If you double click on the task, the Execute SQL Task Editor appears, with several of the properties which are also in the Properties window, including CodePage.
If, in the Editor, you update the value of CodePage, then click OK, the value of CodePage in the Properties window is updated immediately.
I have written a custom SSIS task, which also has the same properties in the Properties window and in the Editor. The Editor also has an OK button. When OK is clicked, the values of the task properties are updated. An example property is FolderToArchive. If I open the Editor, change the value of FolderToArchive and click the OK button, the value of FolderToArchive in the Properties window is NOT immediately updated.
If, however, I select the FolderToArchive field in the Propertiesd window, it is then updated with the value I entered in the Editor.
How do I get my task to update the values in the Properties window, after changing a value in the Editor, when I click the OK button?
I would have thought I would need something like, in pseudo-code,
Task.Parent.PropertiesWindow.Refresh
where task is of type Microsoft.SqlServer.Dts.Runtime.Task and Task.Parent is of type Microsoft.SqlServer.Dts.Runtime.Package.

Hi there,
I'm still pretty new to SSIS, what I am really battling with is getting a custom task to work.
I have developed a custom task, digitally signed it added it to the Global Assembly Cache, written the UI for it - Pretty much as it is done here: http://technet.microsoft.com/en-us/library/ms136080.aspx
but my problem is that when I drag it from the tool box into the control flow pane, I get this message: "The task user interface specified by type name 'XXXXXXXXXXXXXXXXXXX' could not be loaded.
(Microsoft.DatatransformationServices.Design).
Does anybody have an idea of what I am doing wrong here?
Duane.

I've written several custom Control Flow and Data Flow components for SSIS. I'm trying to deploy a new Control Flow Task, however it will not show up in the "Choose Toolbox Items" window.
I have my dll's all in the right place. Because of other painful issues we have not used the GAC, and instead have put our DLL's that are referenced in the following directory: C:program filesMicrosoft SQL Server90DTSBinn. This has worked fine for other custom tasks, but not for this one.
The only things that are different about this transform are the following:
1. Not only does the task inherit from Task, it also implements two interfaces that I wrote.
2. One of the assembly references is actualy an executable instead of a dll. This is unusual, but I've done it with other .NET projects and not had any trouble.
I could move the code I need from the EXE out to a DLL. If somebody knows what could be causing this please respond?

Hi JayH (or anyone). Another week...a new set of problems. I obviously need to learn .net syntax, but because of project deadlines in converting from DTS to SSIS it is hard for me to stop and do that. So, if someone could help me some easy syntax, I would really appreciate it.
In DTS, there was a VBScript that copied a set of flat files from one directory to an archive directory after modifying the file name. In SSIS, the directory and archive directory will be specified in the config file. So, I need a .net script that retrieves a file, renames it and copies it to a different directory.
Linda
Here is the old VBScript Code:
Public Sub Main()
Option Explicit
Function Main()
Dim MovementDataDir
Dim MovementArchiveDataDir
Dim MovementDataFile
Dim MovementArchiveDataFile
Dim FileNameRoot
Dim FileNameExtension, DecimalLocation
Dim CurMonth, CurDay
Dim FileApplicationDate
Dim fso ' File System Object
Dim folder
Dim FileCollection
Dim MovementFile
'======================================================================
'Create text strings of today's date to be appended to the archived file.
FileApplicationDate = Now
CurMonth = Month(FileApplicationDate)
CurDay = Day(FileApplicationDate)
If Len(CurMonth) = 1 Then
CurMonth = "0" & CurMonth
End If
If Len(CurDay) = 1 Then
CurDay = "0" & CurDay
End If
FileApplicationDate = CurMonth & CurDay & Year(FileApplicationDate)
'=====================================================================
' Set the movement data directory from the global variable.
MovementDataDir = DTSGlobalVariables("gsMovementDataDir").Value
MovementArchiveDataDir = DTSGlobalVariables("gsMovementDataArchiveDir").Value
fso = CreateObject("Scripting.FileSystemObject")
folder = fso.GetFolder(MovementDataDir)
FileCollection = folder.Files
' Loop through all files in the data directory.
For Each MovementFile In FileCollection
' Get the full path name of the current data file.
MovementDataFile = MovementDataDir & "" & MovementFile.Name
' Get the full path name of the archive data file.
MovementArchiveDataFile = MovementArchiveDataDir & "" & MovementFile.Name
DecimalLocation = InStr(1, MovementArchiveDataFile, ".")
FileNameExtension = Mid(MovementArchiveDataFile, DecimalLocation, Len(MovementArchiveDataFile) - DecimalLocation + 1)
FileNameRoot = Mid(MovementArchiveDataFile, 1, DecimalLocation - 1)
MovementArchiveDataFile = FileNameRoot & "_" & FileApplicationDate & FileNameExtension
If (fso.FileExists(MovementDataFile)) Then
fso.CopyFile(MovementDataFile, MovementArchiveDataFile)
' If the archive file was coppied, then delete the old copy.
If (fso.FileExists(MovementArchiveDataFile)) Then
fso.DeleteFile(MovementDataFile)
End If
End If
Next
fso = Nothing
folder = Nothing
FileCollection = Nothing
Main = DTSTaskExecResult_Success
End Function

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!

Hi All,
I am using a Data Flow task which copies data from an Excel Source to a SQL Database Table Destination. From 15 columns I require only 10 columns to be imported to the DB Table. So I have mapped those colums. In SQL DB there is a colum called say X, whose value should be the "Remedy" for all the columns which are imported. Is there any task that can achieve it.
Please Help.

I'm writing my first SSIS custom task. I have added Public properties, which appear in the standard task properties window, and to one of them I have added an EditorAttribute as follows:
<Category("General"), _
Browsable(True), _
EditorAttribute(GetType(UIFileNameEditor), _
GetType(System.Drawing.Design.UITypeEditor))> _
Public Property FilesToArchive() As String
[Code] ....
When I select the FilesToArchive property in the Properties window, I get an ellipsis that appears in the property value. When I click on the ellipsis, it brings up the FolderBrowserDialog, which is defined in the UIFileNameEditor class. This all works fine.
What I want to do is to bring up the EditorUI, the one you get when you double click on the task, and also populate that with properties which can be edited. I have a class which inherits DTSBaseTaskUI, which is displayed when I double click on the task.
I can also get properties to be displayed in that UI but I cannot get them to be editable in that UI, using the same technique as in the standard Properties window, as described above.

I am writing my first custom SSIS task and I can see that, if I put a public property into the task, I see that property in the standard Properties window. If I add a property of type String, I can put a value in that property, in the task code, and when I instantiate the task in a package, I can see the value I entered.
To try and get a drop down list property in the Properties window, I declared a property of type Combobox, and indeed a drop down list appears in that property.
My problem is trying to get values in that property. I have used the test items:
Property.Items.add("Fred")
Property.Items.Add("Jim")
But I do not see the values in the drop down list. All I do see is one item with a value of "(none)".

Does 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,

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();
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.

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.

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.

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?
