Hi,
I developed a simple custom control flow component which has several read/write properties and one readonly property (lets call it ROP) whichs Get method simple returns the value of a private variable (VAR as string). In the Execute method the VAR has a value assigened. When I put the value of ROP or VAR into MsgBox I can see the correct value. However when I execute the component I can not see the value of the ROP in the property window. I see the property but its value is empty string. For example when I put a breakpoint to postexecute or check the property before click OK in a MsgBox I would expect that the property value would be updated in SSIS as well. Is there a way how to display correct values of custom tasks properties in property window?
Thanks for any hints.
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 ?
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.
View 10 Replies View RelatedI 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.
Thanks
Is there any way to provide a readonly custom property in the ProvideComponentProperties() method of a custom PipelineComponent implementation?
View 7 Replies View RelatedI wrote a custom task following the outline on MSDN. I signed it and installed it into the Tasks folder and in the GAC.
When I go to an SSIS project and add my task, the properties window shows "Could not get value for property 'd61935d9-430b-4c93-9f3e-a29f720d8659'. Specified cast is not valid." (where the guid is different obviously) for many of the properties.
What have I done wrong?
Update: I know this isn't my code because I tried a simple task that just returns success and doesn't do anything. I get the exact same errors, so I must be installing it incorrectly.
Hi all,
I'm wondering if anyone's accomplished this before - I've been unable to find a whiff of info on how to do this so far.
I'm creating a custom component that I'd like to give a "Derived Column" type of ability to. By that, I mean I'd like to populate a property of my component with an expression (including references to input columns, package variables and functions) and be able to evaluate it at runtime - per row processed by the component.
I would also appreciate any information as to how to provide the interface to allow the user to build such an expression as well - is there a UI function in SSIS I can call to pop up the "expression builder"?
Thanks!
I'd like to be able to hold onto lineageIDs in a list in the custom property of an output object. I found that I can really only easily use an array which is fine but now that I have coded it I cannot set any of the array values programatically. I can't even initialize the array the way I want it. I also cannot change the value in the debugger, it just pops back to zero.
Am I missing something? Here's how I'm trying to do it:
IDTSCustomProperty90 linIDsProperty = output.CustomPropertyCollection.New();
linIDsProperty.Name = "KeyColumnLineageIDs";
linIDsProperty.Value = new int[MAX_KEY_COLS];
for (int i = 0; i < ((int[])linIDsProperty.Value).Length; ++i)
((int[])linIDsProperty.Value)[i] = -1;
(please ignore the \ around the [i], the forum changes [i] into for some reason)
Thanks

I have set a validation error when changing a property in the advanced editor. Unfortunately this validation error is only displayed when you change tabs or press the ok button in the editor.
I have tried calling the validate method within the setcomponentproperty method but the error only show up when ok button is pressed or tab in editor.
I don't want to throw an exception, is there any way you can show a validation error immediately once the user has clicked away / entered / clicked to another property field after entering a property value in the advanced editor that is incorrect.
Thanks
Hi Folks,
I have a task I wrote which does not always update the property value (as seen in the properties pane)
Basically, change something on the form, then update the task host property with:
this.taskHostValue.Properties["Duration"].SetValue(this.taskHostValue, Convert.ToInt32(spnDuration.Value));
Stepping through this, it does exactly what it is supposed to. Having a look at the property value, it confirms it has changed.
Reopening the UI and resetting all the controls returns the expected results.
The package however does not realise it has changed. There is no * next to the package name in the top tabs.
As long as the package thinks it is unchanged, SaveXML does not get called either so the tasks do not persist.
Changing the value on the properties pane works fine though.
The frustrating thing is this is slightly random. Slight in the sense that sometimes it works but most of the time it does not.
The sample code I used was the MS download IncrementTask (Which works BTW) so I can't see it as being a VS / SSIS bug but rather something I am / am not doing. 3 tasks I have written all behave the same. I have to "nudge" them before savign the package.
Any ideas what the problem might be?
TIA
Cheers,
Crispin
Im working through the MS example of "removeDuplicates". I cant seem to figure out how to add custom property for input column.
I added the helper method:
private static void AddIsKeyCustomPropertyToInput(IDTSInput90 input, object value)
{
IDTSCustomProperty90 isKey = input.CustomPropertyCollection.New();
isKey.Name = "IsKey";
isKey.Value = value;
}
I call it from:
public override void ProvideComponentProperties()
{
//...
AddIsKeyCustomPropertyToInput(input, false);
//...
}
public override void ReinitializeMetaData()
{
IDTSInput90 input = ComponentMetaData.InputCollection[0];
if (input.CustomPropertyCollection.Count == 0)
{
AddIsKeyCustomPropertyToInput(input, false);
}
// ...
}
However when I deployed it and added the component to SSIS package - I cant see the Custom Column "IsKey" in the input column properties window.
What am I missing - please help
We have a built a custom control flow task that we use frequently. It has a simple user interface form where we can set certain properties. Problem is, after I configure it once and then copy and paste it all of the internal property settings seem to be lost on the newly pasted task. When I open up the editor for the task all of the properties are displayed visually in the editor form, but the properties pane is empty.
How can this be corrected?
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 am having problems exporting data into a flat file using specific code page. My application has a variable "User::CodePage" that stores code page value (936, 950, 1252, etc) based on the data source. This variable is assigned to the CodePage property of desitnation file connection using Property expression.
But, when I execute the package, the CodePage property of the Destination file connection defaults to the initial value that was set for "User:CodePage" variable in design mode. I checked the value within the variable during runtime and it changes correctly for each data source. But, the property of the destinatin file connection doesn't change and results in an error.
[Flat File Destination [473]] Error: Data conversion failed. The data conversion for column "Column01" returned status value 4 and status text "Text was truncated or one or more characters had no match in the target code page.".
[DTS.Pipeline] Error: The ProcessInput method on component "Flat File Destination" (473) failed with error code 0xC02020A0. The identified component returned an error from the ProcessInput method. The error is specific to the component, but the error is fatal and will cause the Data Flow task to stop running.
If I manually update the variable with correct code page and re-run the ETL, everything works fine. Just that it doesn't work during run-time mode.
Can someone please help me resolve this.
Thanks much.
Untill recently I had a smooth running SSIS package,but suddenly it throws error syaing
"OnError,,,,,,,The result of the expression
"@[User:trTextFileImpDirectory] +"SomeTextStringHere"+ @[User:trANTTextFileName] +(DT_STR,30,1252) @[User:taging_Date_Key]+ "SomeTextStringHere"
" on property "ConnectionString" cannot be written to the property. The expression was evaluated, but cannot be set on the property."
I have child SSIS package running under a parent package (through execute package task)
I have few flat file connection managers in child package for text file import , in which I am building text file path dynamically at run time by assigning an expression in connection string property of connection manager.
The Expression is as follows
"@[User:trTextFileImpDirectory] +"SomeTextStringHere."+ @[User:trANTTextFileName] +(DT_STR,30,1252) @[User:taging_Date_Key]+ +"SomeTextStringHere"
Where @[User:trTextFileImpDirectory] is a variable which contains path of directory containg text
files.Value in this variable is assigned at runtime from parent package's variable,which in turns fetch
value from a configuration file on local server.
With my current configuration this path has been configured to some other server's directory over network ( I.e my package picks text files from some other servers folder over network)
While
"Some string here"+ @[User:trANTTextFileName]" part of file name string.
(DT_STR,30,1252) @[User:taging_Date_Key] Contain the date of processing ,value in this variable is also picked up at run time from parent package variable.
1) So can someone give me some insight into possible reason of failures.
2) Is it possible that problem arises if directory (from which I m picking text files) is assigned password or is there exist some problem in accessing forlders over network ?
3) Or there can be some problem in package configuration at design time( I.e where I m assigning value in variable from parent package vriables)?
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#.
Hello,
I have a group I'll call G4.
The header table row for G4 contains 3 textboxes containing the sums of the contents within G4. The header table row for G4 is visible while it's contents, including the G4 footer table row, is kept invisible until the report user drills down into the group.
When the report user drills down into G4 the footer table row becomes visible and the sums of the contents of the group are displayed for a second time.
At this point I want the sums in the header to be set to invisible when the sums in the footer are made visible by the drilldown.
When I try to reference the hidden property of textbox66 in the G4 footer in order to set the hidden property of header textbox57 in the G4 header I get to this point...
=IIF(reportitems!textbox66.
When it fails to give me an option of choosing the .Hidden property and instead only gives me a .Value.
If I complete the IIF statement manually so that it spells out .....
=IIF(ReportItems!Textbox66.Hidden = False, True, False)
...the report chokes on it.
So my question is, how do I reference the hidden property of one or more textboxes in a group to use as condition checks to set the hidden property of another textbox in that same group?
Thank you for any help you can provide. We are only now beginning to implement reporting services and I have not yet had the chance to research this in greater detail for lack of time.
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 am having trouble initializing my connection. This is the code:

I am use Reporting services 2000 SP2 and discover that the LineHeight property rendered correctly only in renderers for HTML output. PDF renderer, TIFF renderer and client side printing client do not render changes in this property at all.
Is it bug in Reporting services 2000?
Can someone try to change LineHeight property in SQL Server 2005 Reporting services and verify rendering output?
Hello.
within a data flow task I have two OLE DB sources that I am attempting to put into a merge join.
When I connect them to the merge join transformation I get the following error:
The IsSorted property must be set to true on both sources of this transformation.
I understand what this means but I cannot see an IsSorted option in the properties of the OLE DB sources so I can't set it. Can you tell me where it is? for the time being I'm having to put a sort transform in to get it to work.
Thanks

We want to use our styles say "mystyle" on a report. I am surprised that we do not have cssstylename as a property for a textbox?
Ideally, i should be able to add that style in the styles.css file and reference the style name on the textbox. All that would be needed is that it would add an attribute to the rendered html. I wonder if it already exists and i am missing some information?
hi everyone,
According the information provided by BIDS if it have false anulates any message such as msgbox or something like that from the ssis execution. is it true?

I'm trying to figure out this repeatwith property setting. I have a row of textboxes that are labels at the top of the body of my report. Under this row is a list box "LstCategory" with a sublist "SubLstCategory". I set the repeatwith to LstCategory.
When I preview the report in VS it doesn't. When I publish this report in Report Manager it does. When I export from Report Manager (In PDF Format) it doesn't.
What do I have to do so it will repeat in Reporting Services?
Is it normal that In Report Manager that what you view does not export the same way?
I'm new at this altogether. About 4 months in SQL and 1 month with Reporting Services. So be gentle.
