we are have written one custom input language translator SSRS extension which gets input and convert it into another language and send back. In this extension we have written a code to write error messages using event logger. When we running our SSRS reports they are showing message error!. But we are not getting any error in event logger only in SSRS trace log it returns "Data not found at parameter 5".
Following is sample asp.net code. Please do let us know permissions needed on extension so that we can write event log. We are getting error at Eventlog.SourceExists in below code.
System.Diagnostics.EventLogPermission pEventLog = new EventLogPermission(System.Security.Permissions.PermissionState.Unrestricted);
pEventLog.Assert();
if (!EventLog.SourceExists("Report Server"))
{
myLog = new EventLog();
myLog.Source = "Report Server";
}
According to Microsoft, you will not be able to acquire EventLogPermission unless the process is running with Administrator permissions.

This sounds pretty risky to me. You might want to use a different logging mechanism (like Log4Net, etc).

I am trying to do a couple of things within Cognos:
Load Framework Manager and view/modify SQL behind existing models and create new models
Modify existing reports through Report Studio via Cognos Connection
I was given an account on the Cognos application server and I installed Framework Manager. I was given the gateway URL and dispatcher URL from the System Admin and then transferred all of the project files to the server so that I could load the project in question. I'm able to open the .cpf file; however, when going into any models, I get the error:
Unable to access service at URL:
https://xxx.cognos.xxx.xxx:443/ibmcognos/cgi-bin/cognos.cgi?b_action=xts.run&m=portal/close.xts
Please check that your gateway URI information is configured correctly and that the service is available.
For further information please contact your service administrator.
I then contacted the system admin and he indicated that the URL was correct.
Furthermore, now when I try to access Cognos Connection (which worked fine last week), I receive the error:
CM-REQ-4159
Content Manager returned an error in the response header. The error "cmAuthenticateFailed CM-CAM-4005 Unable to authenticate. Check your security directory server connection and confirm the credentials entered at login." can be found in the response SOAP header.
The odd thing is, another member of my team receives this error:
AAA-AUT-0016:
https://xxx.cognos.xxx.xxx/ps/images/space.gif
https://xxx.cognos.xxx.xxx/ps/images/space.gif
https://xxx.cognos.xxx.xxx/ps/portal/images/msg_error.gif
The function call to 'Method.invoke(cmServiceInstance, queryRequest)' failed.
https://xxx.cognos.xxx.xxx/ps/images/space.gif
DetailsExpand:
CM-SYS-5192 An error occurred with Content Manager.
I've done some research (I'm not really familiar with Cognos or even networking) and found that these errors (the ones that I receive) are usually received when trying to run a single report; however, I can't even access FM models or Cognos Connection in general. I also don't understand how we can receive 2 different errors when accessing the same URLs from the same network.
Any guidance would be greatly appreciated. We are using Cognos 10.2.2.

One possible reason is that the user does not have the required "Import relational metadata" capability.
Or maybe it is something to do with the registry
Note: Make sure you backup the registry before making any changes.
see http://www-01.ibm.com/support/docview.wss?uid=swg22015730
Open cmd and type "regedit".
Navigate to [HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Main\FeatureControl.
Right click "BMT.exe" = dword:00002af9.
Delete.
Re-launch Framework Manager.
I have an SQL Database and an ASP.NET website built to put data into the database.
One of the project requirements is to build a system that would let the user upload a Crystal Report to the server and run it as needed. This way, the user could create a customized report (for then turning into management, customers) that wouldn't force them to go through a developer.
I'm looking for suggestions on how to accomplish this goal.
Currently, I'm looking for a way to redirect the database connection in the Crystal Report from the database it was developed with to the database it will eventually run on. However, There doesn't seem to be a simple way to do this.
I'm also investigating the ReportViewer object. However, all the code I have seen involves specifying the query for the report in the code, which isn't acceptable.
One option (which I don't like at all) is to let them write their own queries so they can copy the results into Excel. This would mean a blank textbox and information about the structure of the database. Not a good idea for multiple reasons.
Another option is to create one report for each table (and maybe a few extras), let the user copy the data they want into Excel, and go on their merry way.
tl;dr How do I build a flexible reporting system?
=========================================
Continuation: 08/20/2012
I have decided to go the route of b.pell's extension methods. So far, it has gotten me closer than anything else. My code to bind to the CrystalReportViewer is below:
CrystalReportSource rs = new CrystalReportSource();
rs.Report.FileName = Server.MapPath("ReportFiles/") + Request["reportname"];
string connstring = System.Web.Configuration.WebConfigurationManager.ConnectionStrings["myConnectionString"].ConnectionString;
rs.ReportDocument.ApplyCredentialsFromConnectionString(connstring);
rs.ReportDocument.ApplyNewDatabaseName("myDBName", "mySchemaName");
rs.ReportDocument.Refresh();
CrystalReportViewer1.ReportSource = rs;
This comes very close to working. It works fine on my dev machine, but when I run the code on the server, it gives the following error:
Logon failed.Error in File CrystalReport2 {5D2E82E5-783E-4DFD-A770-C8AE72A51E4E}.rpt:
Unable to connect: incorrect log on parameters. Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. Exception Details: System.Runtime.InteropServices.COMException: Logon failed.Error in File CrystalReport2 {5D2E82E5-783E-4DFD-A770-C8AE72A51E4E}.rpt: Unable to connect: incorrect log on parameters. Source Error: An unhandled exception was generated during the execution of the current web request. Information regarding the origin and location of the exception can be identified using the exception stack trace below.
The error is in this line in the code:
crTable.Location = String.Format("{0}{1}", prefix, crTable.Location.Substring(crTable.Location.LastIndexOf(".") + 1))
When I remove the call to ApplyNewDatabaseName, I am asked to enter the Server Name, the Database name, the Username and the Password or to select Integrated Security. I can't enter the Database Name or the Server Name (those fields are disabled).
Any thoughts?
I think what you're looking for is the Reporting Services, part of Business Intelligence
Or maybe you can setup a UI that let the users pick the tables and columns they need for the report (this way you can limit the information they can access) an write a Dinamic Query Builder Function or something like that.
I answer the changing Crystal Reports connection question a lot (it's something I'd think Crystal would make easier, but I wonder if they don't because that's what their server product does). :D Anyway, you can set the database credentials at runtime. Crystal is very particular in the order it's done, but I have some code that I turned into extension methods that do the trick. This code will go through the main report and all sub reports and change the connection information. This assumes that all sub reports connect to the same database that the main report does (if not, you'll need to modify it to handle multiple connections, but this rarely comes up at least with what I do).
Extension methods to change connection info: http://www.blakepell.com/2012-05-22-crystal-reports-extension-methods
It would be used something like this (although, you're binding to a viewer probably and not exporting, so you could ignore that, this is just for example).
Using rd As New ReportDocument
rd.Load("C:\Temp\CrystalReports\InternalAccountReport.rpt")
rd.ApplyNewServer("serverName or DSN", "databaseUsername", "databasePassword")
rd.ApplyParameters("AccountNumber=038PQRX922;", True)
rd.ExportToDisk(ExportFormatType.PortableDocFormat, "c:\temp\test.pdf")
rd.Close()
End Using
System.Diagnostics.Process.Start("c:\temp\test.pdf")
You could use the Crystal Viewer at this point to deliver the reports and store the report in a database or on the file system (with a db meta data table) and have some predefined connections the user could select from that would be applied when it is run.
You also have the option to write your own front end. In this scenario a user would select a report from your meta data (you could put whatever security on it you wanted, I use AD). Then you can read the report parameters in and lay them out on the web form. When the user fills them in, you then sanatize them and pass them to the report via these extensions and you can output Excel, PDF, Word Doc, RTF, etc. A little more overhead and not the nice preview view, but can work well (I've done something like this in the past). Hope this helps.
About "...let them write their own queries" part of your question.
The solution can be to use some query builder component with friendly user interface which hides from users the complexity of your database and avoid any possible SQL injections.
There are few such products on the market. One of them is called EasyQuery, another one is build by Aspose if I'm not wrong. Try to search in Google for "query bulider for asp.net" or ".net query builder component".
I have two question....
when i drop some Edi file in receive location......if there is some error in file.....we get some error in event viewer(I guesss these are receive pipeline error).....
my first question is
can we se this error in the sql server .................In which database and table we can see event viewer error.
My second question is
can we get this error and write into some file through biztalk.
my first question is
can we se this error in the sql server .................In which database and table we can see event viewer error. --> I guess No.
My second question is
can we get this error and write into some file through biztalk. --> Yes you can do that. following are few ways
1.Use Enterprise Library logging and catch the error in pipeline if you are using custom pipeline and write those errors in flat file
2.if you use SCOM , it will automatically poll all the errors related with BizTalk in event viewer and sends notifications to you.
3.Write a custom service using .net and read the event logs on each bizTalk nodes, later you can either write them in flat file or push them in database tables.
Check out http://msdn.microsoft.com/en-us/library/aa578516.aspx. You could route the message to a file and or SQL table.
If you turn on BAM and EDI reporting there will be a nicer view in the admin console.
When I try to execute an orchestration with something like EventLog.WriteEntry("MyEsb", "Msg"); in Expression shape, I get the exception The source was not found, but some or all event logs could not be searched. To create the source, you need permission to read all event logs to make sure that the new source name is unique. Inaccessible logs: Security. Why?
I'm running Win 7 64bit if this makes any sense.
When you write the event log from any application, the event source needs to be already created, or the application itself will try to create it before writing to it. Unfortunately, creating an event source is an action which requires local admin priveledges.
So you can do two things:
pre-create the event source
make sure the user which your biztalk host is running as is in local admins (bad)
To pre-create the event source is a nicer option. You can do this via the powershell command
New-EventLog -LogName "Application" -Source "MyEsb"
Might seem like I'm stating the obvious but has the BizTalk User got permission to write to the Eventlog? That is, the account of the Host Instance running the Orchestration.
You'll probably find that it hasn't.
HTH
Finally I've found a solution. As the error says, "To create the source, you need permission to read all event logs to make sure that the new source name is unique. Inaccessible logs: Security." So even though BizTalk User account has enough rights to write to the eventlog it has no rights to read EventLog\Security log as stated here in a Note in the Remarks section:
The reason for this requirement is that all event logs, including security, must be searched to determine whether the event source is unique. Starting with Windows Vista, users do not have permission to access the security log; therefore, a SecurityException is thrown.
So I just granted a Read Access to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\eventlog\Security for BizTalk User and the problem was solved.
I had applied the following code as said by you :
byte[] b = YourByteArrayFromDb;
File.WriteAllBytes(MyFilePath, b);
But I am receiving an exception "Access to the path is denied". How do I solve this using ASP.Net with C# ? And is there any format to set the path as string ?
There is file access audit in Windows. You can use it to get detailed info about access faults. All events will be collected into Security Event Log. Steps to achieve:
Define audit on the "C:\Users\attilah\" directory or whole disk via Property->Security->Audit
Switch on audit in the Local Security Policy (Control_Panel->Administrative_Tools)
Look for events in the Security Event Log
Second method is using Process Monitor by Mark Russinovich (www.sysinternals.com)
Apply any method to diagnose a problem.
I think The error message is loud and clear. You DONT have permission to write to that path. Check the permission for the user under which you are trying to write the file.
I have recently run into the same problem, when trying to edit a file copied from a CD-ROM. The file still had its Read-Only attribute on, which caused the very same error.
