.NET Framework :: How To Use Custom Assembly That Uses AxMetadataServiceClient

Oct 8, 2015

I have build a vb.net class that uses the AxMetadataServiceClient (MS Dynamics Axapta model store) this class works like expected in .net app.When I try to create this assembly in sql it fails with this error

Msg 10300, Level 16, State 2, Line 6

Assembly 'System.EnterpriseServices' references assembly 'System.EnterpriseServices, version=4.0.0.0, culture=neutral, publickeytoken= b03f5f7f11 d50a3 a.', which is not present in the current database.

SQL Server attempted to locate and automatically load the referenced assembly from the same location where referring assembly came from, but that operation has failed (reason: version, culture or public key mismatch). Please load the referenced assembly into the current database and retry your request.can't create the assembly since it references it self and can't find it self ?

.NET Framework :: Grant DnsPermission To Assembly?

May 3, 2015

Ported RabbitMQ over to .NET 3.51 over without the SYstem.ServiceModel dependencies.My SQL CLR Proc invokes rabbit to publish a message but then gets a DNS error because of limited permissions:

RabbitMQ.Client.Exceptions.BrokerUnreachableException: None of the specified endpoints were reachable ---> System.Security.SecurityException: Request for the permission of type 'System.Net.DnsPermission, System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'
failed.

[Code] .....

What's strange is that I added the RabbitMQ assembly with the unsafe option so it seems like this should just work with no CAS headaches:

CREATE ASSEMBLY [RabbitMQ.Client]
           FROM 'c:SqlClrRabbitMQ.Client.dll' WITH PERMISSION_SET = UNSAFE
GO

How do I get by the DNSPermission check in SQL CLR?

.NET Framework :: Restoring 2008 Database To 2012 Server With CLR Assembly

Jul 6, 2015

I have a database with deployed CLR assembly on SQL 2008. I recently took a backup for the database and restored it on SQL 2012 server. Everything worked fine except very strange working of CLR assemblies functions.The result of the function is very odd. It manipulates the numeric string and return the result. It is returning very strange result on SQL 2012 as compared to SQL 2008.Example SQL 2008 ManipulateString('1234') returns 2345 On SQL 2012 the same call returns 1155.I am also trying to deploy the same assembly to SQL 2012 server database. I have successfully register the assembly, but the database do not list the exposed methods.

.NET Framework :: Can Integration Services Catalog Be Registered As A SAFE Assembly

Aug 7, 2015

CLR's not registered as SAFE are disallowed on our Network.  It appears that the key associated with the assembly (ISSERVER) may be able to link to the Service Master Key.  If the service master key is created with a (CA) Certificate Authority, is it possible to create the SSISDB that accompanies the Integration Services Catalog as a SAFE assembly?

[adding] BY CA meaning:

ALTER SYMMETRIC KEY [mykey] ADD ENCRYPTION BY CERTIFICATE [myservercertname]

Class And Sequence Diagrams Describing SSIS Framework (for Custom Components)?

Jun 30, 2006

Hi,



Can anyone tell me where I might find the Class and Sequence Diagrams for the SSIS framework (for Custom Components)?



I've just started trying to create some Custom Transform Components and
I'm really struggling to get my head around the component lifecycle
(i.e what methods are called when, with what arguments, and why) with
just the BOL documentation to guide me.



Thanks in advance,

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, 2008

Hello 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 Im very desperate because my VS didnt 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: dll 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,

Using Custom Assembly As A DataSource

Nov 27, 2007

Hi,

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,

Custom Assembly Security

Oct 3, 2007

Hello 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.

My report uses a custom assembly. I have already done the following

1. copied the assembly in the "reportserverin" and the "common 7privateassemblies" area
2. Made the following entry in the rssrvpolicy.config

<CodeGroup
class="UnionCodeGroup"
version="1"
PermissionSetName="FullTrust"

Description="Translation Helper Utility">
<IMembershipCondition
class="UrlMembershipCondition"
version="1"
Url="C:Program FilesMicrosoft SQL ServerMSSQL.5Reporting ServicesReportServerinAMOTest.dll"
/>
</CodeGroup>


3. Added the following line to my assemblyinfo.cs file

[assembly: AllowPartiallyTrustedCallers]

Yet More Issues With Custom Assembly

Feb 28, 2008

I 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

Using Custom Assembly In Ssrs 2008

Mar 25, 2008

I have a custom assembly that I'm trying to use with my resport in Reporting Services in SQL Server 2008.
I keep consistently getting a "Request for the permission of type 'System.Data.SqlClient.SqlClientPermission, System.Data,Version=2.0.0.0, Culture=neutral,PublicKeyToken=b77a5c561934e089' failed" error. Even in preview mode.

- I added <Assembly: AllowPartiallyTrustedCallers()> attribute to the assembly
- I'm asserting the permission in the routine that is doing the database call with the follwing lines:
Dim permission As SqlClient.SqlClientPermission = New SqlClient.SqlClientPermission(PermissionState.Unrestricted)
permission.Assert()
- I went in .net 2.0 Framework configuration and made the assembly fully trusted
- I added the approprtiate codegroup to the rssrvpolicy.config file
- I tried the same assembly on another PC running SQL server reporting services 2005, its working just fine.

what is it that I am missing?

Hi,

I use vs2005 and ssrs 2005.
I have an assembly like

namespace PackageCode

{


public static class Class1

{

public static string GetRequired(bool Split, string Id_StockItem, string InventoryUpdateQuery, string TotalRequired)

I published the assembly to GAC.

I added the dll as reference in rdlc file.
And I get this error when I try to enter this code under a textbox

GetRequired is underlined with a red error line which says "unrecognized identifer" when I mouseover onto it.
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 ?

Returning A Dataset From Custom Assembly?

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.

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!

Rendering A Report Using Custom Assembly

May 17, 2007

I 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!

Deploying A Custom Assembly That Calls A Web Service

Sep 27, 2007

I'm having a terrible time trying to figure out how to do this, does anyone have experience?

My code works fine in the report viewer, but all I get from the deployment is #Error symbols. I've added my custom dll file to the config file and gave it full trust, as well as the URL of the web service I'm calling. I've even modified the rest of the codegroups within the file to FullTrust just in case.

I've also added the [assembly: AllowPartiallyTrustedCallers] to the AssemblyInfo class, and [WebPermission(SecurityAction.Assert)] to the constructor of my custom assembly no avail.

I'm at a complete loss now as to why my deployment cannot run this code. As far as debugging goes, Visual Studio is not located on the reporting server, nor is it an option to have it put there. I've been able to run the code with the web service lines commented out, but as soon as I put even the webservice.Credentials = CredentialCache.DefaultCredentials in I'm greeted with the nice and calming #Error.

Any suggestions?

Cannot Deploy Reports Using Custom Assembly - Access Is Denied

Aug 10, 2007

We have a custom assembly that worked fine with SSRS 2000. Now that we have upgraded to SQL 2005 we get an "Access is denied" error when attempting to deploy reports that reference this assembly. I could swear that when we first attempted it it worked. We decided to make a minor change to the assembly code and that's when the problem started, even though I've since reverted back to the original code to make certain that the minor change wasn't the issue. The assembly is in the proper folder - C:Program FilesMicrosoft SQL ServerMSSQL.2Reporting ServicesReportServerin - and the reports are referencing the current version. I've searched high and low on the web for an answer but have found nothing even remotely helpful. All this code does is return a string...it's not doing anything that should require any additional security; and even then I doubt if there would be a problem when deploying.


The full text of the error is:
Error while loading code module: Reporting, Version=1.0.2778.12272, Culture=neutral, PublicKeyToken=null. Details: Could not load file or assembly 'Reporting, Version=1.0.2778.12272, Culture=neutral, PublicKeyToken=null' or one of its dependencies. Access is denied.


Any ideas? Anyone? I'm at my wit's end on this!

Custom Assembly : Retrieving Data From From Configuration File.

Mar 7, 2006

Hi all,

my problem is that: I do read informations (e.g. connectionString) from configuration file by one custom assembly.
My environment is RS2005, VS.NET 2005 Prof.Edition, WIN2003 Server SP1, .NET Framework 2.0.50727
The scenario is that:
A text box into my report require a function contained into MyCustom.dll. This code do read information from MyCustom.dll.config.

This file contains:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<connectionStrings>
<add name="IS2009cfg" connectionString="data source=servernameinstancename;initial catalog=dbname;user id=xx;password=yy;" />
</connectionStrings>
<appSettings>
<add key="DefaultHeaderLogo" value="This is a test" />
</appSettings>
</configuration>

Using
ConnectionStringSettings conn = ConfigurationManager.ConnectionStrings["IS2009cfg"];
the result is null.

Also using
string defaultHeaderLogo = ConfigurationManager.AppSettings["DefaultHeaderLogo"];
the result is null.

MyCustom.dll and MyCustom.dll.config are located into locations of Report Server and Report Designer, with this Build Events on succesfully build:

rem Copy custom assembly to ReportDesigner location...
copy "...mydeveloplocation...inDebugMyCustom.dll" "C:Program FilesMicrosoft Visual Studio 8Common7IDEPrivateAssembliesMyCustom.dll"
copy "...mydeveloplocation...inDebugMyCustom.dll.config" "C:Program FilesMicrosoft Visual Studio 8Common7IDEPrivateAssembliesMyCustom.dll.config"
rem Copy custom assembly to ReportServer location...
copy "...mydeveloplocation...inDebugMyCustom.dll" "C:Program FilesMicrosoft SQL ServerMSSQL.4Reporting ServicesReportServerinMyCustom.dll"
copy "...mydeveloplocation...inDebugMyCustom.dll.config" "C:Program FilesMicrosoft SQL ServerMSSQL.4Reporting ServicesReportServerinMyCustom.dll.config"

The question is simple: where I do locate configuration file for obtain value during report execution?

Many thank's in advance

Custom Assembly Accessing DB With A NON Hardcoded Connection String?

Mar 25, 2008



We use reporting services to report on our SQL 2005.

I wanted to have a function that translates a filter (parameter) in one RDL from IDs to Names to be able to show a summary of what the user selected when he executed the report.

Instead of writing this function in the .Code, I said great, lets use custom assemblies.


PROBLEM: I see examples on how to enable a function in such dll access to DB, but they all hardcode the connection string in the vb code. that seems useless to me. Each customer will have different server name, I need to get the connection string from the sme (shared data source) used in the catalog's folder. just like the RDl is using it. how do I do that?

Null Reference Error When Using A Custom Assembly That Uses An App.config File

Apr 7, 2008

I 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?

Assembly.Load Can't Load My Custom Assembly From The GAC.

Mar 7, 2007

Hi there.

I have an assembly, call it A1, that I've deployed to a SQL Server 2005 database. I can use the managed stored procedures from A1 in SQL Server no problem.

In A1 there is a bit of code which uses the Assembly.Load() method, so load another assembly and use instances of class found in that external assembly. However, when I run the managed stored proc in A1 that uses Assembly.Load() I get the error:

Could not load file or assembly 'A1, Version=1.0.0.0, Culture=neutral,PublicKeyToken='????' or one of its dependencies. The system cannot find the file specified.

(note: for security I've changed some of the above line).

So I changed the Assembly.Load() to use

System.Data,Version=2.0.0.0,Culture=neutral,PublicKeyToken=b77a5c561934e089

I re-built the project, re-deployed it and ran the code in SQL Server - it worked. I could create an instance of a System.Data.DataSet for example. So why can't I load my own custom assembly? My assembly does have a strong name and it's installed in the GAC. I wrote a console app to try and Assembly.Load() my custom assembly and that worked fine (it was also running on the same server as the SQL Server).

So it's defiantely the SQL Server that can't 'see' my customer assembly. What do I need to do this assembly so that SQL Server will allow me to Assembly.Load it, just as it can with System.Data?

Thanks
Jas.

Request for the permission of type 'System.Security.Permissions.UIPermission, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.
Ive tried everything that I can think of on the server to make this work.
I finally put together a Win 2003 box with SQL 2005, IIS, and RS 2005 running on it in a virtual machine to be 100% sure I had a standard clean install and deployed the report and Im getting the same error.
Below Ive included a basic standalone RDL file that demonstrates my issue. I get the error referenced above when I deploy the RDL below. Any ideas or suggestions are greatly appreciated?
