Null Reference Error When Using A Custom Assembly That Uses An App.config File
Apr 7, 2008I have a custom assembly that uses a config file to obtain database connection settings. This dll is then used by my sql report. I have added refrerenced to all the required dll's in my report and added the required code groups to all the necessary files. I have also placed my app.config file in C:Program FilesMicrosoft SQL ServerMSSQL.3Reporting ServicesReportServer and C:Program FilesMicrosoft Visual Studio 8Common7IDEPrivateAssemblies
However when I actually run the report in the designer (vs2005) I am receiving Null reference exceptions when my code tries to read my config file because it is reading the machine.config file and not my app.config file. If I hard code my connection string everything works fine.
Can anyone tell me why the machine.config file would be referenced instead of my app.config file and how I can stop it from doing this?
Custom Assembly Behaves Differently In The Report Designer And Report Manager
Mar 18, 2008Hello everyone,
I created a custom assembly using C# to transform some binary data into text, and in this assembly I used one win32 dll developed by our customer to help me to do the tranformation.
The code I used to call the win32 dll is like below:
[DllImport("tdasuie.dll", EntryPoint = "AlrtLogConditionToText",
ExactSpelling = false, CharSet = CharSet.Auto, SetLastError = true)]
private static extern UInt32 AlrtLogConditionToText(Byte[] pbCondition, StringBuilder pszText, UInt32 dwSize);
I defined a C# method to call the above win32 method and return a string. Then in the report, I called this C# method to get the correct string.
In the report designer, the C# method in the custom assembly can return the correct string in the preview window. But after I deployed the report into the report server, the textbox will only display "#error" in the report manager web page.
Can anybody help me on it? Thanks a lot.

Problem Deploying Custom Report Item. Items Shows In Preview Screen In VS, But Not In Server Deployed Report
Nov 29, 2006I have developed a custom report item that works fine in design and preview mode while in Visual Studio. I cannot get it to show up on my deployed reports. Here's what I have done so far:
1. Deployed the report using Visual Studio
2. updated the rsreportserver.config file with the following entry:
<ReportItems>
<ReportItem Name="PedigreeChart" Type="Uabr.Rap.PedigreeChart.PedigreeChartRenderer, Uabr.Rap.PedigreeChart" />
</ReportItems>
3. Updated the rssrvpolicy.config file with the following entry.
<CodeGroup
class="UnionCodeGroup"
version="1"
PermissionSetName="FullTrust"
Description="This code group grants Uabr.Rap.PedigreeChart.dll FUllTrust permission. ">
<IMembershipCondition
class="UrlMembershipCondition"
version="1"
Url="C:Program FilesMicrosoft SQL ServerMSSQL.3Reporting ServicesReportServerinUabr.Rap.PedigreeChart.dll" />
</CodeGroup>
I've also tried using the StrongNameMembershipCondition with no better results.
4. The dll and its dependencies are copied to the bin directory of the report server.
5. When I load a report with this custom report item on it, the report loads fine with no errors or warnings in the log file (even with verbose tracing). The area where the custom item should be is just white. It's almost like Reporting Services isn't registering the item correctly.
This is particularly frustrating because the report works fine in Visual Studio - apparently I configured that correctly. Any suggestions would be greatly appreciated. I'm stumped.
Custom Report Items
Feb 4, 2008Hi All,
I am using SQL Server 2005 Reporting Services and have successfully created and deployed a Custom Report Item to use instead of the standard Chart Control.
This new Item works fine in both Report Designer (Visual Studio) and when generating Reports on the Report Server
However, I have a requirement that the same chart style must be available in Report Builder. Unfortunately, when using Report Builder to create a new report I can only select Tabular, Matrix or Chart style, and the chart option uses the standard style which is not suitable.
I cannot see any obvious way of including a Custom Report Item within Report Builder, so I have 2 questions :
Can I use a Custom Report Item in Report Builder? None of the samples or tutorials that I have found give any indication of whether this is possible.
Thanks in advance

Custom Report Items With CustomData
Feb 5, 2008Hi,
I'm currently on the task to develop a custom report item to display date values from a data source in a Gantt-chart-alike way.
I took a look at the documentation and the examples (especially [1]) but the documentation I found mainly concentrated on the case of assigning a single value to a custom property. As far as I can see I need to access the data source directly to retrieve the data I'd like to show. In the best case I could retrieve data sets only from a certain data grouping. But that's where I'm stuck. I realize I have to define the CustomData property in the designer component, but I have no clue what to set for DataRowGroupings, DataColumnGroupings, DataRows and so on.
I hope somebody can point me to some documentation about the contents of the CustomData class. The MSDN documentation I found is utterly incomprehensible to me.
Thanks in advance!

Rendering A Report Using Custom Assembly
May 17, 2007I have created a custom assembly and referenced it and the program builds successfully. When I try to run the report in design mode, it will not render, it throws an exception when it tries to create a PDF. When I remove the assembly, the reports work well. So I'm not sure what it is that I'm doing wrong - does anyone have any suggestions?
namespace Calculations
{
public class calcPercentage
{
public static decimal Percentage(decimal decValueOne, decimal decValueTwo)
{
decimal decPercentage = 0;
if (decValueOne == 0 || decValueTwo == 0)
{
decPercentage = 0;
}
else
{
decPercentage = (decValueOne - decValueTwo) / decValueOne;
}
return decPercentage;
}
}
}
Then in my textbox I put:
=Calculations.CalcPercentage.Percentage(SUM(Fields!PreviousYTDExpenseAmount.Value, "Template_OutputData_Sales"), SUM(Fields!PreviousYTDExpenseAmount.Value, "Template_OutputData_CGS"))
I referenced the assembly and added it to C:Program FilesMicrosoft Visual Studio 8Common7IDEPrivateAssemblies and I still get that error message so I do not know what the problem is.
The line where the exception occurs happens here:
byte[] bytes = MyReport.rvOutput.LocalReport.Render("PDF", null, out mimeType, out encoding, out extension, out streamids, out warnings);
Thanks so much for you help! If you have any suggestions about my next error...i'm all ears!
Reporting Services :: External Assembly Reference Same DB Data Source As Calling Report?
Aug 25, 2015I have a SSRS 2012 report which references a custom c# assembly.  This report exists in multiple environments (alpha, beta and  production ) which are each associated with different data sources.
Is there a way for the assembly to determine the datasource used by the calling report so it can also connect to it?
SQL Server 2014 :: How To Return Bitmap Image From Custom Assembly To SSRS Report
Dec 11, 2013I am using the QRCode4CS class [URL] .... to generate QR codes.
I can use the following code to successfully return a bitmap image to a picturebox in a Windows Form Application.

Here is the custom code I am using.
Public Function QRCode(ByVal RetailerId As String) as Byte()
Return QRCode4CSCreateQRCode.CreateQRCodeClass.CreateQRCodeImage(RetailerId)

[Code] ....
What data type can I successfully return to SSRS to display the image?
How To Reference Items From Different Database?

I execute my stored procedures fromDB_Internal.Everytime I want to read the tables in DB_External, I have to refer tothe table as DB_External.dbo.tableName.Is there a better way of declaring the database DB_External up frontin the stored procedure so I don't have to pre-fix "DB_External.dbo."in all the table names?Thanks in advance,June Moore.
View 1 Replies View RelatedSSIS - Need To Reference .NET Assembly Without GAC
Jan 25, 2007I have a .NET assembly that I need to reference and use within my SSIS script task.
The only way I can acheive this is to strongly name my assembly and put it in the GAC.
This is not possible as my assembly is already in production and uses other 3rd party assemblies that would also need to be registered in the GAC.
As a workaround, I have created a .Net console application that references my assembly, that call from a SSIS Process Task.
Does anyone know of another way I could use my .NET assembly within my SSIS package?
Any help appreciated.

Assembly Reference Issue
Oct 8, 2007I have an external reference to an assembly that uses the following external references of its own:
System
System.Data
System.Xml
In BIDS everything works without any issues so I decided to deploy the package to my database server. In doing so, I copied the DLL reference for my external assembly to obth the GAC and the v2.0.50727 folder and I even went as far as to copy the assembly folder into the Program Files folder.
Despite these efforts, I keep obtaining the following error:
The script threw an exception: Could not load file or Assembly 'MyComponent, Version-1.0.0.0,Culture=neutral,PublicKeyToken=f5bb784d481b2932' or one of its dependencies. The system cannot find the file specified.
I checked the version of my DLL in all 3 places and both the version and the token are the same.
I checked the properties within the script task and it has the exact same path to the v2.0.50727 folder (which shouldn't matter given the GAC...).
Does anybody has any ideas why this exception is occurring?
Thank you for your help!

Programatically Creating Dataflow Tasks Require Assembly Reference
Jan 17, 2007Hi,
I am creating dataflow tasj using following
Imports Microsoft.SqlServer.Dts.Runtime
Imports Microsoft.SqlServer.Dts.Pipeline
Imports Microsoft.SqlServer.Dts.Pipeline.Wrapper
These refer to Microsoft.SqlServer.DTSPipelineWrap.dll and Microsoft.SQLServer.DTSRuntimeWrap.dll. While these assemblies were already there in my dev machine I don't find these files in production enviornment for SQL server 2005. I am refering these assemblies from following path in my local machine : C:Program FilesMicrosoft SQL Server90SDKAssemblies.
How to install these assemblies in prod env, offcource one option is to copy it and then put it in GAC thru script . Why does not it gets installed while installation of SQL server 2005. Are these assemly dependent on SP1 ?
Thanks

Custom Assembly SecurityException
Feb 26, 2008
Hi,
I'm trying to do something rather weird, but I really need it. I'm trying to launch a SSIS package from a report
I built a custom assembly with one method that loads a package from file and then executes it. The assembly works fine.
I added the custom assembly to the report properties, instantiated the class in the assembly (the method is not static), called the method from the report (a textbox renders the string return value from the method).
I added the
Code Snippet[assembly: System.Security.AllowPartiallyTrustedCallers]
attribute to the AssemblyInfo.cs file
Created the strong name for the assembly.
Got the PublicKeyBlob with ILDASM, used it to add a new CodeGroup with the "StrongNameMembershipCondition" in the policy configuration files of ReportDesigner (RSPreviewPolicy.config), ReportServer (rssrvpolicy.config) and ReportManager (rsmgrpolicy.config).
Copied the dll in the bin folders of ReportServer and Visual Studio PrivateAssemblies.
I keep getting the awfull #Error message on the report when viewing it from ReportManager or ReportServer (in preview mode in VisualStudio all is well because security is not applied to user code).
I tried debugging:
- created a solution with two subprojects, one is the report, the other one is the assembly
- marked the report as the Startup Item
I get a SecurityException in debug and debuglocal modes when I try to instantiate a SSIS package.
Code SnippetPackage = new Package();
While digging in the exception call stack, it turns out I lack a permission for accessing unmanaged code (the source assembly of the exception is mscorlib). Also in the ouput window, while starting debugging i see a lot of SystemArgument exceptions in mscorlib.
I am perfectly aware that in order to be able to launch a SSIS package from code I referenced Microsoft.SqlServer.DtsRuntimeWrap.dll, so in desperation I added another CodeGroup in the aforementioned config files for this dll (StrongNameMembershipCondition) and copied the assembly in the deployment folders.
1: I would really like to know how to get the whole thing working. I find rather strange that even though I set the FullTrust
PermissionSet for my assembly (and the Microsoft.SqlServer.DtsRuntimeWrap assembly) I keep getting security exceptions.
While exploring the web for help I saw I need to assert all individual permissions for every restricted resource I'm accessing in the custom assembly, problem is I don't know exactly which ones I'm accessing and, being new to .NET security, I don't know how.
Surely I need to assert a file IO permission to load the package from file, a sqlclientpermission if I am accessing SqlServer in the package, and perhaps a unmanagedcode permission, given the the exception I described earlier (perhaps the Microsoft.SqlServer.DtsRuntimeWrap assembly is not managed code or is accessing some other unmanaged assembly).
Again, I wouldn't know how.
...and last
2: I tried modifying the assembly to only load a string from a file.. I had some problems with security but I got it working once, but I haven't figured out how exactly 'cause when fiddling around to understand things, I lost the working configuration. Really stupid, I know....
While testing this version of the assembly I followed an advice I found on some blog and restarted IIS and Reporting Services system service..
Is this always necessary after modifying the assembly source ? Do I need to restart every time both IIS AND Reporting Services
I would really appreciate every bit of help or advice anyone has to offer.
Thanks in advance.
Using Custom Assembly && Gacutil && Sn
Jan 22, 2008Hello experts,
I need some help please.
Yesterday I get the answer that I had to use an assembly if I would like to use a function as global. Right now I€™m very desperate because my VS didn€™t recognize my DLL.
I get the error: "Could not load file or assembly .....The system cannot find the file specified."
After red the threads I tried to use gacutil.exe to add my assembly to the cache.
This action fails with the error:€? Failure adding Assembly to cache. Attempt to install an assembly without a strong name.€?
After that I tried to build a strong name through the follow execute:
Sn €“Vr ClassLibrary.dll. This action fails too. I get the follow Error description: €œdll does not represent a strongly named assembly€?.
What made me wrong?
Is there an easier workaround?
Have someone a good Idea could help me?
Hope to hear you soon.
Best regards,
Alex
Using Custom Assembly As A DataSource
Nov 27, 2007Hi,
I was wanting to get some data through a custom assemly. I can successfully return a primitive data type such as a string and put it in a textbox, but I really need to return more data, and possibly bind it to a Table.
For example, maybe I could return from the call a Dataset and bind it as a DataSource which then can be bound to a Table, or maybe a array of string.
Is this possible? If so, are there any good examples that you know of?
Thanks,
AussieGuy

Custom Assembly Security
Oct 3, 2007Hello Everyone,
When I run my report from report manager, I get the following error message
Failed to load expression host assembly. Details: Request for the permission of type 'System.Security.Permissions.FileIOPermission, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.

Yet More Issues With Custom Assembly
Feb 28, 2008I have developed a custom assembly to render a signature from an array of bytes in an SSRS Image control. The assembly works perfectly in the designer. It is strong-named and has the AllowPartiallyTrustedCallers attribute applied to it; I have deployed the assembly to the "%SQL SERVER%MSSQL.3Reporting ServicesReportServerin" folder; given it fulltrust permissions in the rssrvpolcy.config file; made sure that the NTFS file security is correct; and the assembly just doesn't appear to be called. The assembly doesn't execute when I use the "F5" popup preview mode on my development machine, either.
I don't get any error messages in the report, I just don't get any image output, either. The rest of the report elements render correctly. Of course, the SSRS log files are useless. Enabling the Verbose trace switch doesn't yield any useful information, I don't think, except that in the lines pertaining to running my signature-enabled report there are no mentions of even attempting to use my custom assembly.
I have attempted to enable object access auditing (both success and failure) to determine if my assembly is even being accessed by SSRS and there are no audit messages in the Security Event log.
Can anyone offer any other troubleshooting suggestions?
Thanks,
Matthew Belk
Table Items Custom Sort
Feb 15, 2007hello
i am currently trying to port a "Business Objects" report to SQL Server Reporting Services.
in B.O., there is a possibility to define the order of the table values by previewing the table values and moving them up or down.
Example : the dataset contains data for 3 items, so in the Custom Sort window, I will see these 3 items and I can order them by moving them up or down in a listbox.
is this possible to do in Reporting Services ?
Can Anything Other Than An Image Be Used In Custom Toolbox Items
Sep 10, 2007
I have developed a renderer that renders the xml to paint a rectangle with textboxes in all the right places based on the data retrieved off the database. When i render the a complete report to the reportviewer i have no problem.
I need however to render the rectangle into a custom report item for reusability and different scenarios. This just seem to be impossible since it seems like I cant use anything other than an imagemap to render custom report items. Is this true?
To make sure you understand....in other words....
Is there a way to develop a Microsoft.ReportingServices.ReportRendering.IRenderingExtension that renders the required xml like rectangles/textboxes etc. and then migrate this to a custom toolbox item. It just seems like this should be a very easy thing to do and something regularly needed. For example when you want to use textboxes in certain positions within a rectangle to draw a organisational chart.

And when I run the report I get #Error in that textbox.
I dont have a reporting server.I get the data from a dataset.
What to do now ?
Thanks for help.
Returning A Dataset From Custom Assembly?

Include Custom Code Assembly
Sep 20, 2007
OK. I created a few functions in a Public Class called SSRSFunctions. I built it and deployed it to my desktop. What do I do now? Can it be included as standard functions in the function list within SSRS? Do I add a reference to the Class at the solution level? At the report level? If all I do is add a reference at the report level, I may as well add the functions to each report's code window, which is what I have been doing. I'd at least like to add a single reference to my solution if I can't get it added to the function list.
Thanks!
