I have been getting to grips with writing a custom data processing extension for using a supplied dataset. I have got it working OK so far, but I don't see how to make use of relational data. There's plenty of code for walking through the fields, but nothing to walk through the tables. Since this clearly has to be possible can someone tell me where I'm going wrong?
Thanks
John Williams.
I've created a custom Data Processing Extension and I've implemented the IDBCommandAnalysis interface so that my reports can enter parameters and pass them to my Data Processing Extension.
My question is, how do I extract the value from the Parameters coming from the report? Where do the parameters get passed off from the report? I can query the Parameters collection and my report gets prompted in Preview mode to enter something for the parameter but I can't find the spot where it gets passed for processing.
I am using Custom Data Processing Extension to call a stored procedure. Iam getting following error when creating a dataset in report designer using the extension. I wrote the code in c#.
could not update a list of fields for the query. verify that you can connect to the data source and that your query syntax is correct.(Details-Object reference not set to an instance of an object.)

Hi , all Microsoft BI experts here,
Thanks for your kind attention.
I am having a question as stated in the subject title, yes, when we want to deploy scorecards to reporting services, as the prerequisite, how can we install and register the scorecard custom data processing extension with the Microsoft reporting services server?
I am looking forward to hearing from you shortly and thank you again.
With best regards,
Yours sincerely,
hello,
I have written a Custom Data Processing Extension for SSRS 2005.
The Report Server is in SharePoint integrated mode, this works perfect except for the extension.
When I want to set a DataSource in SharePoint (WSS 3.0), the extension is not in the ComboBox.
This works well on another server with the same extension.
The DLL file of that extension is copied in the reportserver bin folder.
I have added the references in the rsreportserver.config and rssrvpolicy.config (see below).
Code Snippetrsreportserver.config
<Data>
<Extension Name="SPSLISTS" Type="ICom.ReportingServices.SharepointListsExtension.Connection,
ICom.ReportingServices.SharepointListsExtension" />
<Data>
Code Snippet
rssrvpolicy.config
This code is located inside the CodeGroup with Name="SharePoint_Server_Strong_Name".
<CodeGroup class="UnionCodeGroup"
version="1"
PermissionSetName="FullTrust"
Name="SPSLISTS_CodeGroup"
Description="Code group for my SPS LISTS data processing extension">
<IMembershipCondition class="UrlMembershipCondition"
version="1"
Url="D:Program FilesMicrosoft SQL ServerMSSQL.3Reporting ServicesReportServerinICom.ReportingServices.SharepointListsExtension.dll"
/>
</CodeGroup>
I already tried re-installing Reporting Services and the add-in for SharePoint but the problem remains.
Does anyone has an idea of what's wrong here?
Thanks in advance,
Tom
Hello,
I'm writing a Data Processing Extension for SSRS 2005 that allows you to use a WSS 3.0 List as a dataset.
This works for one list per dataset. Now I am trying to extend the extension to allow multiple lists in a dataset because I want to join lists on a common field (INNER JOIN). The problem is that I can only return one DataTable to the Report Server with the DataReader. Does anyone know if it is possible to return multiple DataTables (without the join)?
I'm a student, working on this project. I know Visual Basic.net but only started last month with Data.
Thanks in advance

I am using an OLEDB data source connecting to an Access database. Using SQL Server 2005 SP2 Workgroup Edition.
I can build the report fine and view it in Visual Studio. When I deploy the report and try to run it on the Report Manager site I get this error
An error has occurred during report processing. (rsProcessingAborted)
An attempt has been made to use a data extension 'OLEDB' that is not registered for this report server. (rsDataExtensionNotFound).
When I go to the Shared Data Source, this message appears beside the Connection type field
The data processing extension used for this report is not available. It has either been uninstalled, or it is not configured correctly.
What am I doing wrong??
I need help about this , What i've done so far is a data processing extension that gets its data from a WS , I use it as a datasource for a report , That report will be displayed withing an ASPX page containing a reportviewer control that displays that report , The problem is catching errors that occurs withing the data processing extension .. ,
When i debugged the extension i saw that after throwing an exception the code ends up inside the "cancel()" event inside the IDBcommand implementation...
In all examples for a data processing extension i could find online they always have a comment saying the cancel is not implemented and throw a NewUnsupportedExtension()..
What happens is i get some uninformative , non-userfriendly error from the reporting services ,
something like "an error occurred during the report processing(rssomehing)"
How should i go about handling those exception that happened inside the data processing extension?
I've tried catching the error inside the event of the reportviewercontrol - reporterror but it seems that event don't fire when those errors are generated..
Any help on how to approach this would be highly welcome
Hi all,
My query should be pretty simple to answer by the gurus. I have SQL Server Express Advance series installed at my system along with VS 2005. I tried the reporting services (remote mode) to display a report in the report viewer on my aspx page. The report simply uses an SQL query to get the result. Everything works fine and dandy!
However if i want to get data from my own data set, i used a webservice and ussed the XML data source option in the report to traverse through the XML. In the preview mode of the RDL everything works fine however when i deploy or rather run it using report viewer on my webpage, it gives an error that 'XML' has not been registered as an extension etc.
I looked in the rsserver config file, it IS configured. The only answer i have is that the EXPRESS version of SQL only supports the regular SQL data sources. I do not understand if that was the case, why does the preview mode work fine??
If i am correct then for the next release the ms developers should disable that or rather give a more meaning full error. I spent an entire day fideling around just to find out that it isnt supported with debates all over the place as to why in the world does it work in the preview mode?
Anyhoo, to get around that issue, i am wondering if the Custom Data Extension would work on the SQL Express or not? I am assuming it wouldnt. Please clearify this. Ideally all i want is to access my own data set in the report, no SQL queries or whatever, CDE seems the way forward but does SQL Express allow it?
Many thanks guyz.

Zeeshan
(btw, its only been two days since i started working with reporting services, so be gentle :-D )
Target: RS2000, Oracle-DB
I build a CDE on the base of the FSi-Example.
Deploying worked fine
here is the problem:
I build a new shared data source, but can't edit the connection string. the button disables itself. why?
Therefore I copied the string from an existing datasource.
I supplied the auth-data and all seemed to be fine.
when i want to build a dataset with this datasource, I get something like this:
"no connection to database possible
check connection string and test connection. "
But this is not possible because of the disabled edit button.
Can anyone help please? What's wrong?

Hi,
The custom security extension generates the following error, when try to access Report Manager. The specifications are as follows.
1. Its 64-bit SQL Server (Reporting Services) and installed as default instance.
2. The Report Server is accessible programmatically. I can publish, view reports without problems, but Report Manager gives an error.
3. Another instance (named instance) of Reporting Services with the same custom security extension on same server is working fine. Report Manager opens up without problems.
4. Both the instances working fine since 3 installation and configuration (3 months back). Now, only the Report Manager of the default instance is not openeing up.

This is the error i got: The report server is not responding. Verify that the report server is running and can be accessed from this computer.
I went to Services and saw my Reporting Services is stopped. Tried to start Reporting Services and it timed out.
Hi All,
My application is currently integration with reporting services using custom security extension. I have my own USER and ROLE database to determine who/which role can access certain reports.
My question is how to give access a report to be viewable by everyone? I dont want to assign all users or all roles to achieve this.
The other thing that I found out is, let say I change the name one of the user/role. Because of this, the authorization will fail because the old name/role is not in the DB anymore. Is this expected? or is there a workaround it?
Your help is appreciated.
Thanks!
Roles Table:
RoleID, RoleName
<RoleID1>, Allow_ClientFolder
<RoleID2>, Allow_ClientReportA
<RoleID3>, Allow_ClientReportB

<UserID2>, <RoleID4>
<UserID2>, <RoleID5>

<UserID2>, <RoleID1>
<UserID2>, <RoleID3>
e.g.
when the <UserID1> clicks on the "home" link show only "Client" folder and when <UserID1> clicks on the "Client" folder only "ClientReportA" will show.
Here is the accessable map for each user:
<UserID1>
Client

Question:
What is the best way to implement CheckAccess? At first I thought I can access the item names and I can test authorization through that, but AceCollection contains operation permission of the accessing object.
Greetings. I have developed our own custom security extension, implemented forms based authentication, and can authenticate from report manager, report server and sql studio. So far so good.
However, when it comes to Authorization, i'm unclear in a few areas and would appreciate if someone could help me out with the following questions. It should be noted that in the code I have granted an administrator user full access to all operations and permissions, and then tested against both an administrator user and a normal user.
IAuthorizationExtension.GetPermissions summary says
"Returns the set of permissions granted a specific user for an item in the report server database."
Inparticular, the secDesc parameter is supposed to contain the security descriptor associated with the item.
However, with our extension this parameter is always null, even if I have already granted access for a user, which is confirmed through logging in CreateSecurityDescriptor.
Through the report manager or sql studio I can see that the permissions have been created, so I can't understand why I never see them in the GetPermissions method? This then (seems to) flow through to the various CheckAccess methods, where the users are authenticated, but are not authorized to perform any operations. i.e. in report manager a user has no folders or reports available.
Is RS authorization designed around the concept that the details will always be stored in it's own database?
Ideally, we'd like to have the various roles, users and function authorizations defined in our own security framework. This is working great for the authentication aspect of the extension, but unless there is a mechanism which exposes the details of the particular authorization process (e.g. the name of the folder being viewed or report being run), then I can't see a way we can implement it. Unless i'm missing something fundamental of course!
Using Report Builder as the Administrator user (or any other user), I can see no data models available, even though I have created them via Report Manager, and I get the following exception trying to open up the list of reports:
System.Web.Services.Protocols.SoapException: The permissions granted to user '' are insufficient for performing this operation. ---> Microsoft.ReportingServices.Diagnostics.Utilities.AccessDeniedException: The permissions granted to user '' are insufficient for performing this operation. at Microsoft.ReportingServices.Library.ListChildrenAction.PerformActionNow() at Microsoft.ReportingServices.Library.RSSoapAction.Execute() at Microsoft.ReportingServices.WebServer.ReportingService2005.ListChildren(String Item, Boolean Recursive, CatalogItem[]& CatalogItems)
I have implemented a report server proxy (inherited from ReportService2005) as per the example, to pass through the authorization cookie. Any clues as to what could be wrong?
Finally, I suspect part of my problem may be in assignment of users to System Roles ("System Administrator" and "System User"), I'm not sure if these are meant only for Windows Authentication? I can see no way of assigning these roles to any of my users using Forms Authentication.
Thanks for any help or advice you can give!
Hi,
I am trying the get the custom security extension samples to work on my machine. I have installed everything according the sameple help file. However, i am getting a "Authentication Ticket is not issued by LogonUser." error after I attempted to log on to the report manager thru UILogon.aspx page. I already created an admin user. Upon a closer inspection, I realized that the authentication went thru okay, however, the authentication Ticket Name contained in the "RSAuthenticationHeader" has a duplicate value of "sqlauthticket, sqlauthticket". So apparently, the report server added this value twice to the response header. Has anyone seen this error before? How would you fix it? Also to bypass this error, I parsed out the header and take the correct auth ticket name, now report manager just redisplays the logon page and not letting me thru. Has anyone have seen that before? I am running in Win 2003 server, IIS 6, .NET 2.0 and SQL server 2005 enterprise version.
Thanks for the help,
Eric
Good Morning..
We're having a heck of a good time trying to implement our first CDE project in SSRS 2005.
In our SDE class library we have included an App.Config file where we want to store configuration settings..
Trouble is that when we view the configuration settings or connection string settings in debug mode, they're not being read for some reason..
Here's our app.config file:
-------------------------------------------------------------
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<configSections>
</configSections>
<appSettings>
<add key="eventLogName" value="FocusDPEEventLog" />
</appSettings>
<connectionStrings>
<add name="PassConnString" connectionString="Data Source=SOMEDATASOURSE;Persist Security Info=True;User ID=SOMEUSERNAME;Password=SOMEPASSWORD;Unicode=True"
providerName="System.Data.OracleClient" />
</connectionStrings>
</configuration>
-------------------------------------------------------------
Here's what our Immediate window Debugger is tellin' us about our configuration settings:
-------------------------------------------------------------
ConfigurationManager.AppSettings
{System.Configuration.KeyValueInternalCollection}
[System.Configuration.KeyValueInternalCollection]: {System.Configuration.KeyValueInternalCollection}
base {System.Collections.Specialized.NameObjectCollectionBase}: {System.Configuration.KeyValueInternalCollection}
AllKeys: {Dimensions:[0]}<----incorrect should be 1
ConfigurationManager.ConnectionStrings
Count = 1 <----ok, is one, but the wrong 1, see 3 lines down...
base {System.Configuration.ConfigurationElementCollection}: Count = 1
ConfigurationManager.ConnectionStrings[0]
{data source=.SQLEXPRESS;Integrated Security=SSPI;AttachDBFilename=|DataDirectory|aspnetdb.mdf;User Instance=true}<--Should be PassConnString
base {System.Configuration.ConfigurationElement}: {data source=.SQLEXPRESS;Integrated Security=SSPI;AttachDBFilename=|DataDirectory|aspnetdb.mdf;User Instance=true}
ConnectionString: "data source=.\SQLEXPRESS;Integrated Security=SSPI;AttachDBFilename=|DataDirectory|aspnetdb.mdf;User Instance=true"
Name: "LocalSqlServer"
ProviderName: "System.Data.SqlClient"
Now notice the stuff in bold...I have NO IDEA where this gosh-danged thing is reading, but it doesn't seem like it's the app.config file in our class library...
thanks..

Hey, I was just wondering if someone could point me in the right direction on an issue. I've got the authentication portion of a custom security extension working properly (while authorization is just sort of giving everyone a pass) and all of my Googling efforts seem to be bearing little fruit. Now that authentication is in place, whenever I try to deploy a report from Visual Studio, it comes up with an error.
The error is that it is getting the authentication html login page set in web.config (as I expected), while it was looking for an xml page. I'm a bit new to this side of things so I'm not really even sure where I should be looking to see what kind of xml page it wants and such.
I don't need anyone to bother explaining the entire thing to me as I should be able to figure it out once I can get a start, but as I said I just need a kick in the right direction because my Google-fu has failed
Which component should be used to process dataset as a whole, and not on per row basis? I have need to process dataset conditionally (condition based on dataset), e.g. if a special row is present in dataset than dataset should be processed in a special way. Should I maybe use one Script Transformation to determine if dataset satisfies condition (and store that result into a variable), and then based on that condition (variable value) perform or not processing (using Conditional Split and Script Transformation)?

Can anyone help at all here? I've seen about 10 articles on this one but none appear to be relevant. I have a complex report comprising many sub-reports which runs successfully in a development environment. When deployed to an environment which comprises a separate report sever and report server DB I get the above error even when I try and browse to any of the sub-reports.
The sub-report is using an OLEDB connection to an SSAS DB and its command text is set as:-
=Code.GetQueryString(parameters)
Where GetQueryString is a function in the code section of the report which returns some MDX based on the supplied parameters. I obviously know the function works because it works in development mode.
I have tried to determine what is going on from the logs but the only messages I get are those above. I've set the data sources on the server up to use valid Windows Credentials stored on the server so I don't believe the issue is one of authentication
Any thoughts or tips in helping to diagnose the cause of the problem would be greatly appreciated.
Hi,
I'm trying to deploy Reporting Services on an Internet-facing web server using a custom security extension (forms authentication). We will be putting Report Manager on the Web Server outside of the firewall, and Report Server on another machine inside the firewall. When testing the solution in a development environment with Report Manager and Report Server on the same box, the solution works fine.
When testing it using the Internet-facing environment described above, it almost works but there seems to be an issue with the authentication cookie that is generated. Here's what happens:
1. User enters credentials on UILogon.aspx and submits form.
2. In the code-behind, LogonUser() is called through a web service proxy and the authentication cookie is returned successfully. The code used here to set the cookie is the same code used in the Forms Authentication sample that ships with RS2005.
3. The user is redirected to Folder.aspx, and the request hangs for a while, and eventually kicks you back out to UILogon.aspx, as if it lost the authentication cookie. When doing a trace on the HTTP header, the cookie is still there.
Is there anything special I need to do to make the Report Server "see" the cookie when I have Report Manager and Report Server on different machines?
Any help would be much appreciated!

Currently we are using Custom Delivery Extension for SSRS 2008R2 We are planning to move it SSRS2012

if not what code changes we should do?
Is it possible to have a Reporting Services dataset be returned from a custom assembly? I need to produce data for a graph that is not easily queried from the database and I am already familiar with using a custom assembly in an RS report.
What I would like to do is have a method that fills a dataset and returns it to the report for processing. Is this possible?
I am running SQL 2000 and RS 2000.
Thanks.
Hi there!
For setting different languages on the column haeders i need to access a dataset from a custom code function call. I want to pass a parameter to the function that will allow me to find a specific item in the dataset - like a lookup function.

Is there any solution? Every hint will be helpful!

HI All,
Is there any way to pass report dataset to Custom function as object?
Regards
Sith.
Hi,
I'm developing an ASP.NET application that creates on-demand reports with Reporting Services 2005 in report server.
I use a custom data set that contains the data that I want to bind to the report, and I use a WebService to pass that DataSet to the reporting services to accomplish my purpose.
The query passed to the reporting services is:
<Query>
<Method Namespace=http://myNameSpace.com Name="GetDataSetForReport"/> <SoapAction>http://myNameSpace.com/WebService/GetDataSetForReport</SoapAction>
<ElementPath IgnoreNamespaces="True">GetDataSetForReportResponse{}/GetDataSetForReportResult{}/diffgram{}/ReportDataSet{}/MyTable{Fields1,Fields2,Fields3,..,FieldsN,Image}</ElementPath>
</Query>
This works well and all the fields are displayed in the report fine except the Image Fields, that are not showing (the red X appears instead of the image).
The issue is that all the data that is bind to the dataset is contained in a SQL Server 2005 database, and the Image column in the table of that database is a VARBINARY(MAX) field (I insert the image into the database table).
Also, when I created the dataset in .NET, the column type of the dataset I declared for the Image field was Byte[], but that didn't work for me. I've also tried to declare as the field type Byte,SqlByte,Image,SqlBinary, etc without succesfull results.
I've also tried creating a XML Schema, declaring the Image field as base64Binary, then do DataSet.ReadXMLSchema(myschema) and then retrievied the data from sql server and filled the dataset, Again, the Images doesn`t display.
For finnishing my unsatisfactory tests, I've also tried to handle the image data with a MemoryStream object:
MemoryStream mem = new MemoryStream();
MemoryStream oStream = new MemoryStream();
mem.Write((Byte[])dr["Image"],0 , ((Byte[])dr["Image"]).Length); //dr is the datareader used to read from the DB
Image image = Image.FromStream(mem);
try
{
image.Save(oStream, ImageFormat.Png);
}
catch{}
newRow["Image"] = oStream.GetBuffer(); //newRow is a row of the custom DataSet.Table passed to the SSRS.
But again, the Image is not showing.
Any suggestions?
Thanks for you 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
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 ?
I recently installed the Teradata .NET data provider and I am trying to use named parameters and multi-value parameters in my SQL. I am finding information on this topic hard to come by.
In order to get parameters to work do I need to write my own Teradata data extension from scratch, expand an existing data extension to work with Teradata, or can I simple edit my .config files to point to a generic extension wrapper already existing?
Thanks!
