Is Task.WaitForMe Property Ignored By SSIS Runtime?
Mar 24, 2007
Can the WaitForMe Task property be used for building eventing based tasks (that is, "tasks with no defined execution lifecycle"), as Haselden's IS book terms it?
The SSIS run-time would appear to never interrogate this property.
I tried setting a breakpoint in a custom task on the WaitForMe
property. The breakpoint was never hit at run-time. Design-time only. It seems that the run-time ignores this property.
The documentation states that "On completion of any task, the runtime examines tasks that are still running in
the container, and if any of these tasks have WaitForMe set to
false, those tasks will be canceled." Well, the tasks with WaitForMe set to false are in fact not cancelled (e.g. System::CancelEvent is not signalled).
The intention of the WaitForMe Task property is to allow for event based tasks to not prevent a package (or other container) from finishing if the event never happens.
Tasks like the WMI Event Watcher, Message QueueTask set to receive, and third party tasks like file watchers, or service broker queue receivers would seem to fall in this category.

Hi,
I have a package with 3 different tasks.
Like:
1. Execute Sql Task
2. Execute Sql Task
3. Execute Sql Task
4. Execute Sql Task
ESQL1 will get max(id) from table and then based on the ID the remaining needs to be work.
Ex:
If the ID=AUS-Sdy-1
then ESQL2 will update the tbl1 and return one IDkey based on this return key the ESQL3 will
update a tbl2. ----------*( i want to disable ESQL4)
else
If the ID=AUS-Sdy-2
then ESQL3 will update the tbl1 and return one IDkey based on this return key the ESQL4 will
update a tbl2. ----------- *(i want to disable ESQL2)
Thanks

SSIS data flow transformation - Lookup task - best practice concerning Cachetype
I would like to know if there's any best practice concerning the CacheType property for the the Lookup task. Default value is "Full", but if the SSIS package is working with at lot of data, i.e. +10 mill. records from the OLE DB source to be handled through a variated numbers of data flow transformation tasks, it must have an impact memory usage if the lookup table also is a large table, i.e. +8 mill. records? When should I consider turning the property value to "none"

Hello,
I am having a hard time setting the executable path for an Execute Process Task in SSIS. I have a variable that is initialized at package statup which holds the path to an executable in Windows. When I set the property "Executable" Path in an expression, I get a warning that the path for the executable is not set. One workaround was to try and initialize the variable with a bogus path with the hopes that the "correct" value will be written on run-time. NO LUCK. I still get the error and I cannot run the package until I put a static path.
Does anyone have a clue as to what is going on??

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.

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 am having a Data flow task in For each loop which will gets 100 sourcetable names and 100 target table names...
am having a simpleData flow task which trasferes from OLEDBSource to OLEDBDestination.
I am repeating the Dataflow task which transfers from sourcetablename extracted from for loop to a destination table var.
The problem am gettting is for the first table it is able to transfer correcly because I did mapping for those tables at design time...but for the next coming sourcetable-desttable (which r having different no of cols,datatypes) its giving Validation failed...and...needs to refresh metadata....
is there any way to refresh the metadata of Data flow task (I set the property of OLEDBSource validate external meta to false then also same error is coming)

You can set the default value of a reporting services parameter by any expression.
But with code I'm NOT allowed to do:
Parameters!myParam.Value = CDate("01.01.2007")
This is cause Value property is read-only.
So the question would be:
Are there any way I set a parameter value in runtime ?
Hope anyone can help...

Hi all
I have a flat file.I am trying to set the value for the property "HeaderRowsToSkip" during runtime.I have set an expression for this in my "flat file connection manager". But this is not working.The connection manager is not able to take the value during runtime.
My expression is as follows:
DataRowsToSkip : @[user:: Var]
where "Var" is my variable which gets the value from the rowcount component and trying to set it back to the "HeaderRowsToskip" property.
I ve even tried setting the value to the "HeaderRowsToSkip" property in the expression builder.
Its not working....
Can anyone help me out in solving this????
Thanks in advance

Hi all,
Here is my situation. I need to disable a task at runtime. I have a script task that configures a boolean variable at runtime and sets its value to either true or false based on a condition. And also i have already set "disable" property of the component to get value from the boolean variable. The problem here is that the component gets the default value which we give during variable creation instead of getting the configured value.
Am i missing out anything. thanks in advance.
Regards,

I've been playing around with building custom components for SSIS. I've been doing workflow for years (using Java and Oracle). The company I worked for had a framework for publishing data that allowed for user interaction. That's something I'd love to be able to do in SSIS.
Is it possible to create a custom task that interacts with the user at runtime? So, the user starts the SSIS package. At some point, the process pops up a dialog (Windows Form) that asks the user to set a date using a calendar control.
Any thoughts?

Hi,
I am currently trying to create a Script Task which reads in a file containing meta-data which then dynamically creates a Flat File Connection Manager and configures it using this meta data. After perusing various newsgroups and articles, it seems that I need to be able to reference the Dts.Runtime.Wrapper to do this. I have tried using the Add Reference dialog, but it does not contain a reference to this namespace. I can reference this namespace from a "Script Component" but I am unable to reference it from a "Script Task". Is this a known issue or am I just not doing something correctly? If anyone could give me any pointers it would be greatly appreciated. Thanks!

I 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.

I am importing data from xls file to a db table with a dts. In the time of the dts creation I am using 'Transform Data Task Properties' GUI window to map incoming xls fields (source) to the table columns (destination).
Question: Is there any way to invoke the 'Transform Data Task Property' GUI window in dts runtime and use it to change the mapping dynamically in the run time?
Thanks, Vadim.

Hi,
In a custom task I have a property of type Hashtable. This property gets changed by a custom UI. After changing the value and closing the UI, the Hashtable is properly filled during investigation in the validate() method.
Now saving the package and inspecting the XML file of the package, there is only this entry:
<DTS:ObjectData><InnerObject><PromotionCodes Type="12" Value=""/></InnerObject></DTS:ObjectData>
So it seems, that the value is empty and there is no further data to the object. Trying to reopen the saved package, the opening fails with something like (Had to translate it my own from german):
Error loading '<PackageName>' : Error loading a task. The contact information for the task is ''. This problem occurs on an error during task loading.
There should be a out of the box possibility to save collections or do you have to implement Load/Save XML your own if you have complex datatypes as properties? As the package has the element of the property included (but empty), it seems it tries to save it.
Anyone a hint. Anybody occuring the same behavior?
Thanks T.

I'm programmatically loading a package that was created with VS 2005. The last task in the package is a Send Mail Task. It has two properties, FileAttachments and ToLine, which are set to expressions whose values come directly from package variables. The package runs in debug and non-debug (under VS) correctly.

I've created a Union All data flow task which unions string fields from a couple of queries. I found that I needed to increase the length of the string field in the queries. Increasing the length causes an error in my Union All task. I can't seem to find a way to change the property of the fields in the Union All task. Most of the other data flow tasks have an advanced editor where I can change the length or type of the fields on the input and or output. I can't seem to find this for the Union All task.
Is there any way short of deleting the Output column and recreating it? (I like the order of my original output columns)
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

hello guys,
I am having trouble with using disable property in the expression for data flow task. Here is the issue as explained below-
lets say i have 3 tables TableA, TableB, TableC from which i need to export data. So i create a table (TableList) where I save these table names and a unique id to these tables. e.g.
TableList will have-
TableName TableID
TableA 1
TableB 2
TableC 3
in the ssis package select these tableNames & Ids from tableList in Execute SQL Task. And assign the result set to a variable object (@TableList.
Then i use For Each Loop Container (For Each ADO Enumerator) , to loop through these tablesnames & iDs
Inside this loop container, i define three data flow tasks one for each table. So i have DataFlowTaskA (For TableA), DataFlowTaskB(For TableB), DataFlowTaskC (For TableC).
Now for a given table selected in the iteration, only the corresponding DataFlow Task should be exeuted. e.g. For the 1st iteration, if TableA is selected then only DataFlowTaskA should be executed and DataFlowTaskB& C should be skipped.
In order to achieve this, I am using a 3 variable @FlagA, @FlagB, @FlagC (type Boolean) one for each Table. and use the value of these flags for the "Disable" property of the data flow task (so @FlagA will be used for Disable property in the Expression for Data FlowTaskA, and so on..)
SotThe First Step inside the Loop, I use Script Task. (Input for the script task: read variable is @TableID and Read/Write varaibles are these 3 flags)
In this script task, I initialize these flags to true or false appropriately. So this is what i do
If (Dts.Variables("TableID").Value.ToString = "1") Then
Dts.Variables("@FlagA").Value = False
Else
Dts.Variables("@FlagA").Value = True
End If
If (Dts.Variables("TableID").Value.ToString = "2") Then
Dts.Variables("@FlagB").Value = False
Else
Dts.Variables("@FlagB").Value = True
End If
So in the 1st iteration, (if TableA comes) @FlagA=False and B&C will be True.
So the Disable property for DataFlowTask will be set false and for others it will be set to True. Thus, only DataFlowTaskA will be executed.
And this action should be repeated for each input table. this is the logic.
However only for the 1st iteration(say TableA is selected) it behaves as above. i.e. DataFlowTaskA is executed and DataFlowTaskB & C are skipped. But in the 2nd iteration(say TableB is selected) , it again executes DataFlowTaskA and doesnt exeute B & C (where it should have executed B & skipped A&C).
I do set daelay validation to true for all these but it still it doesnt working as expected. Even I checked the values for all the flags for each iteration and they seem to get the correct values. But somehow Diable propery in the expression not behaving as it should.
Am i missing anything. Do i need to set any other property to make this work.
I apprecite any help.
Thanks

Hi guys,
The default Engine Thread property of a data flow task is set to 5, is this the best setting? what if I would like to run complex data flow tasks on multi-processor machines, should I increase the engine thread? If so, then what is the recommended Engine Thread number for running complex data flow tasks in a multi processor system?
Even if i am running simple data flow tasks on a multi processor machine, should I change the engine thread?
Thanks!

Hi All,
I have the following issue, i want to make dynamic the Argument property of the Execute Process Task but i couldn't able to do so, i have posted several times , hopefully i will get a solution today. I am using the following Argument to execute (winzip) program.
Argument: /e C:FTPFile1.zip C:FTPUnzipped
This Argument works but since File1.zip gets change every time, i mean it will be File2.zip, thus i have to change it manually on the Execute Process Task every time, however i want it to change by itself.
To make it clear, the /e mean winzip usage for extract file, the C:FTPFile1.zip is where the zipped file is, and the C:FTPUnzipped is where i dumped the unzipped files. as you see the file name will change every time like File1.zip, File2.zip, File3.zip, etc... Thus i want to make it daynamic, for example if i execute today File1.zip, then i have to execute tomorrow File2.zip automatically, and then File3.zip etc, that means the source file is changing every time, how do i make it then to be Dynamic.
Please help, i need your input badly.
Thank you in advance,

Hi,
I am facing a very strange issue with the Send Mail Task:
I am fetching the recipient from a Recordset and storing it in a variable (MailList).
Now, I modify the Send Mail Task to include an Expression which updates the "ToLine" property with the email address in the "MailList" variable.
Moreover, I am not hard-coding the "To" property in the "Mail" tab of "Send Mail Task Editor" and leaving it blank. Now, it does not allow me to execute the package and gives me a "Package Validation Error" saying: No recipient is specified.
Any solutions?
Thanks in advance.

This task or container has failed, but because FailPackageOnFailure property is FALSE, the package will continue. This warning is posted when the SaveCheckpoints property of the package is set to TRUE and the task or container fails.
I have just spotted the message above in one of my log files.
I've never noticed it before. Is it new in SP1? I'm guessing it must be.
If so - good job. This is a very important addition because the behaviour of checkpoints without setting FailPackageOnFailure=TRUE is not intuitive (in my opinion).

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?

We're having some issues migrating things we wrote in BIDS to other boxes.
It would seem that to use Fuzzy match (which we are really happy with):
1> You can write a DTSx package that uses Fuzzy Match inside BIDS and run it on Standard Edition
2> You cannot run this package outside of BIDS except on a server that has Enterprise Installed
3> If you have Standard Edition installed on a machine, and want to run a DTSx that uses Fuzzy match,
you have to de-install absolutely everything and re-install everything with the Enterprise edition CD and patch it.
In our environment, we want to run DTS packages from C# code. Up to this point, we have Enterprise edition on the server, and standard edition on the developers workstations because they are provisioned with MSDN licenses; some developers have standard edition (because they like having a local instance to play around with).
Apparently we have to install Enterprise on every single developers workstation in order for them to test dts packages from inside a C# program!! But it's obviously installed already because it runs from BIDS. This doesn't make any sense to us.
Did we set something up wrong? We're looking at hours and hours of work to reload all the workstations... to run one program that calls a DTS package from c#.
