Value Of A Readonly Property Of Custom Task Is Not Updated In Property Window
Apr 17, 2008Hi,
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.
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 ?
Adding Custom Property To Custom Component
Aug 17, 2005What 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 RelatedCustom Task - Custom Property Expression
Aug 16, 2006I 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.

Errors With Custom Task (Could Not Get Value For Property ...)
Jul 5, 2007I 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.
Custom Components - How To Evaluate A Property As An Expression?
Apr 11, 2008
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!
Unable To Set Values In Array Custom Property
Apr 21, 2006I'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
Charlie.
Validation Error On Custom Component Property
May 28, 2008I 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
Custom Task Not Updating Property Values Or Saving.
May 2, 2008Hi 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
Custom Property For Remove Duplicates Transform Input Row
Oct 15, 2006Im 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
Copy && Paste Of Custom Task Loses Internal Property Settings
Sep 21, 2006We 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?
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.

Changing Code Page Property Using Property Expression Doesn't Work
Jun 16, 2006I 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.
(URGENT) Cannot Be Written To The Property. The Expression Was Evaluated, But Cannot Be Set On The Property
May 7, 2008Untill 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)?
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#.

Readonly Setting For Database
Jan 29, 2004we have a database that only serves Select requests (no OLTP) for our very high traffic websites.
what are the benefits of turning on read-only setting for the database if there are no transactions occuring in the database?
does sql server put locks on tables for SELECT statements?
is it the same as using HINT (NOLOCK) ?
thanks

Readonly Access On Tables
Mar 1, 2005Hi,

Thanks..
Database Is ReadOnly When I Attach It...
Oct 12, 2007Using SQL Express in this case, I have a database on one machine using one instance of SQLExpress that I detach. I then copy the database to a USB drive and take it to a different machine and attach it to a different SQL Express instance and it comes in as ReadOnly and I know of no way to change it.
One difference is that I have different users on the two systems, is that the cause? I wouldn't think that this would cause the database to show as ReadOnly, thoughI would just think that I may not be able to access it aside from using sa.
What is the likely cause of this?
Thanks

ScriptComponent With Multiple ReadOnly Variables
Dec 11, 2006I'm having trouble with a script component in which I'm trying to use two ReadOnlyVariables. If I use only one of the two variables, everything works without issue. If I use both of the variables (as part of a comma-delimited list) I get the following:
The variable cannot be found. This occurs when an attempt is made to retrieve a variable from the Variables collection on a container during execution of the package, and the variable is not there. The variable name may have changed or the variable is not being created.
I don't believe the variables themselves are the problem. Both are scoped to the package level and I can use either of them if I have it as the only variable. Seems bug-like, but thought I'd get some ideas before pursuing that route.
Replicated Readonly Db And Temporary Tables
Mar 20, 2007I have two replicated databases i.e.

2. Database 2 is a replica of Database 1 and all reporting / BI applications point to this db. This is read-only.
Is it possible for reporting applications, pointing to Database 2, to create temporary tables in the read-only database?

View 6 Replies View RelatedRestore Readonly Filegroup Sqlserver 2000
Sep 26, 2007
Hi,
I have a database running on sqlserver 2000. This database (let's call it TestDatabase) has 2 filegroups called 'PRIMARY' and 'SECONDARY', and is bulk-logged. The 'SECONDARY' filegroup is set to readonly since no data gets changed there by the applications, it is read-only data. Sometimes this read-only data needs an update, so I need to update the data in the 'SECONDARY' filegroup by running some long data-operations. These data-operations are executed and checked on a another database (which is a backup of TestDatabase) called TestDatabaseDemo. When everything is correct in TestDatabaseDemo we can copy all objects from the 'SECONDARY'-filegroup of TestDatabaseDemo to the 'SECONDARY'-filegroup of TestDatabase using DTS. This takes a long time and I want to try if I could speed up things by using the following strategy:
Take a full backup of TestDatabase
Restore full backup as TestDatabaseDemo
Run long-running data-operations on TestDatabaseDemo
Take a backup of TestDatabaseDemo
Restore only the 'SECONDARY'-filegroup from TestDatabaseDemo to TestDatabase, and keeping the 'PRIMARY' filegroup from TestDatabase as it was at that moment.
Suppose we arrived at step 5, I am executing the following commands:
Code Snippet
--make full backup of TestDatabase
backup database TestDatabase to DISK='G: emp estdatabase.bak' with init
--make full backup of TestDatabaseDemo
backup database TestDatabaseDemo to DISK='G: emp estdatabasedemo.bak' with init
backup log TestDatabase to DISK='g: emp estdatabase.log'
--restore secondary filegroup from TestDatabasedemo-backup
restore database TestDatabase FILEGROUP='SECONDARY' FROM DISK='G: emp estdatabasedemo.bak'
with move 'TestDatabase_Data_Secondary' to 'G: empTestDatabase_Data_secondary.ndf', NORECOVERY
--restore primary filegroup from Testdatabase-backup
restore database TestDatabase FILEGROUP='PRIMARY' FROM DISK='G: emp estdatabase.bak'
with move 'TestDatabase_Data' to 'G: empTestDatabase_Data.mdf', NORECOVERY
--restore log and try to get db onlin
restore log TestDatabase FROM DISK='g: emp estdatabase.log' with recovery
I get the following error:
The log in this backup set terminates at LSN 6000000021500001, which is too early to apply to the database. A more recent log backup that includes LSN 6000000022400003 can be restored.
When trying to execute "RESTORE DATABASE TestDatabase WITH RECOVERY; " as last statement
I get error:
The database cannot be recovered because the files have been restored to inconsistent points in time.
How i can restore the read-only filegroup correctly?
