Error message: Unable to cast object of type 'System.DBNull' to type 'System.String'

Hi everyone, I have recently installed a trial version of SDL Trados (a computer-assisted translation software) and at some point (when I try to create a new translation memory) this error message appears: Unable to cast object of type 'System.DBNull' to type 'System.String' Is this a problem with the software or the laptop ? If it's the laptop, can you please help me solve this ? Thank you,Caroline

UNABLE TO CAST OBJECT OF TYPE 'PROFILECOMMON' TO TYPE 'PROFILECOMMON'

I have four web application configured on the IIS with .Net Framework 2.0
All the applications are working fine except one.
If the system / server, restarted. The Application throws an error message "UNABLE TO CAST OBJECT OF TYPE 'PROFILECOMMON' TO TYPE 'PROFILECOMMON'"
When I searched for the issue, they have mentioned that the temporary
Profile class clashes with your ProfileCommon class.
By setting <profile enabled="false"> you are telling it to NOT generate the dynamic, temporary Profile
class and use your own instead.
On every restart, I need to change the attribute value to make it work.
Can you please let me know, why it crashed on server restart? How it can be resolved ?
Root cause???
Please help on this.

Crystal Reports Server Error - Unable to cast object of type

Hi Everyone,
Not sure if this is the right place to post this question but couldn't find a Crystal Reports Server section.
After doing a windows update on my crystal reports server the following error now occurs when trying to log into .Net InfoView -
An error has occurred: Unable to cast object of type 'CrystalDecisions.Enterprise.InfoObject' to type 'BusinessObjects.Enterprise.Desktop.InfoView'.
I found the following article which I followed and re-installed the .net components as well as ensured all services are enabled.
Article: https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/oss_notes/sdn_oss_boj_bip/sap(bD1lbiZjPTAwMQ==)/bc/bsp/spn/scn_bosap/notes%7B6163636573733d36393736354636443646363436353344333933393338323636393736354637333631373036453646373436353733354636453735364436323635373233443330333033303331333233303335333433323337%7D.do
The error still occurs.
I did some further investigation and found that a similar error occurs in the Admin Console when I try and open the Crystal Report DataSources.
This is the error page that comes up

I'd try creating a new Application Pool just for running businessobjects and crystalreportviewers11 and nothing else.
Although the apps are .NET, it uses COM Interop for functionality, so using a common app pool with other versions will collide.
Beyond that - if you have a SAP Business Objects support contract - you might open a new SAP Incident ticket.

Vsdbcmd error: Unable to cast object of type 'Sql100Synonym' to type 'Microsoft.Data.Schema.Sql.SchemaModel.ISqlColumnSourceBase'.

I am implementing synonym in a database to pass-thru to another database to replace an existing table.
E.g. CREATE
SYNONYM [dbo].[Table1]
FOR [server1].[database1].[dbo].[Table1]
I am getting an error such as below when I try to deploy it with vsdbcmd tool as below:
vsdbcmd /Action:Deploy /dsp:SQL /p:TargetDatabase=database1 /ManifestFile:"deploymanifest" /Script:"database1.sql"
CAQuietExec: An unexpected failure occurred: Unable to cast object of type 'Sql100Synonym' to type 'Microsoft.Data.Schema.Sql.SchemaModel.ISqlColumnSourceBase'.
I can't find anything related to this error on the net. I appreciate any help on this.
Thanks,
Keith

Hello Keith,
Your issue seems related to deploy some database, is it SSDT deployment? It seems VS General is not the right forum for your case, please choose the right forum for your case, like SSDT forum.
I read your post and it seems your 'Sql100Synonym' does not meet the type requirement, what's it in your project? What do you want to deploy?
Best regards,
Barry

Unable to cast object of type InfoObject to DestinationPlugin

I have created a web application to show the list of scheduled reports and with their destination Info using Business objects sdk. Locally on my computer i am able to show all the reports and the Ftp information. But when i move this application to QA server the application returns an error with a message.
"Unable to cast object of type 'CrystalDecisions.Enterprise.InfoObject' to type 'CrystalDecisions.Enterprise.DestinationPlugin"
I have noticed that the returned type of Object by the query on QA server is of type "InfoObject" and on localbox "CrystalDecisions.Enterprise.Dest.Ftp"
Query
Select * from ci_systemobjects where SI_NAME= ''", "CrystalEnterprise.Ftp"
Assemblies required by application are registered in the GAC with same version and same public token
Please let me know if anyone has a answer for this casting exception.

Snippet:
Dim ftp As New Ftp(infoObject.PluginInterface)
Dim ftpOptions As New FtpOptions(ftp.ScheduleOptions)
You wouldn't be doing a direct runtime cast.

Ted Ueda

Hi,
If you were running 5.1 version, that would also mean that you were running packages under SQL 2005.
And if you are now running SQL 2008 with BPC 7.0, you should also review all your customized packages. In fact, BPC tasks in SSIS are not the same between SQL 2005 and SQL 2008.
In addition, I would recommend to upgrade your SQL server version to SQL 2008 SP1 cumulative update package 6 (prerequisite). Not sure if you're still running this CU.
Hope this will help.
Best Regards,
Patrick

Unable to cast object of type infostore to type report

Hi all,
Does anyone know what causes the message:-
system.invalidcastexception: unable to cast object of type 'crystaldecisions.enterprise.infoobject' to type 'crystaldecisions.desktop.report'
Everything works perfectly in my development environment but as soon as I try to put the code live I get the error.
it is happening in the following lines of code:-
        Dim CEinfoObjects As InfoObjects
        Dim CEReport As Report
        Dim CEParameters As ReportParameters
        Dim CEParameter As ReportParameter
            CE_SQL = "SELECT SI_PROCESSINFO.SI_PROMPTS "
            CE_SQL += "FROM CI_INFOOBJECTS "
            CE_SQL += "WHERE SI_ID = " & ReportID
            CEReports = ceInfoStore.Query(CE_SQL)
            CEReport = CEinfoObjects(1)
            CEParameters = CEReport.ReportParameters
I tried changing the ceReport type to an InfoObject type and the system then fails trying to get the parameters. (ReportParameters is not a member of InfoObject)
The only differences I can see is that my dev machine has Crystal XI SP4, Crystal 2008 SP0 and Crystal Server XI SP4 installed while the live environment only has Crystal XI SP4.
I tried installing the 2008 runtime to see if that would make a difference but it has not.
I tried reinstalling the XI runtime but it has not worked either.
Is there something that needs to be changed on the enterprise server? This is also running on XI SP4 and the files match the dates and times on my dev machine.
Any help or pointers would be appreciated.

Unable to cast object of type 'Oracle.DataAccess.Types.OracleDecimal'......

I have some Oracle Tables with sequences for primary key and stored procs in packages to wrap up the insert commands. The sequences field are all declared as NUMBER.
I also have Datasets based on the tables and a DataAdapter for each package. The Datasets see the primary keys as System.Decimal. The DataAdapter sees the output primary key parameter to the stored procs as OracleDecimal.
tmp.Parameters.Add(new OracleParameter("P_ID", Oracle.DataAccess.Client.OracleDbType.Decimal, ParameterDirection.Output));
tmp.Parameters["P_ID"].SourceColumn = "ID";
When I call the Update on the DataAdapter the update happens on the DB and then I get the following error
System.ArgumentException : Unable to cast object of type 'Oracle.DataAccess.Types.OracleDecimal' to type 'System.IConvertible'.Couldn't store <231> in ID Column. Expected type is Decimal.
----> System.InvalidCastException : Unable to cast object of type 'Oracle.DataAccess.Types.OracleDecimal' to type 'System.IConvertible'.
If I change the Oracle parameter to Oracle.DataAccess.Client.OracleDbType.Int32 or Oracle.DataAccess.Client.OracleDbType.Int64 it works fine - any ideas why that would be ? I would expect System.Decimal to map to Oracle.DataAccess.Types.OracleDecimal.

Hi,
If I change the Oracle parameter to Oracle.DataAccess.Client.OracleDbType.Int32 or Oracle.DataAccess.Client.OracleDbType.Int64 it works fine - any ideas why that would be ? I would expect System.Decimal to map to Oracle.DataAccess.Types.OracleDecimal.
I'm trying to do the same, but no matter what I do, I get the OracleDecimal error. Parameter is defined as:
bq. this._adapter.InsertCommand = new global::Oracle.DataAccess.Client.OracleCommand(); \\ this._adapter.InsertCommand.Connection = this.Connection; \\ this._adapter.InsertCommand.CommandText = "INSERT INTO PERSON\r\n (ID, SURNAME, NAME, BIRTHCITY, EMSO)\r\nV" + \\ +"ALUES (:ID, :SURNAME, :NAME, :BIRTHCITY, :EMSO) RETURNING ID INTO :ID";+ \\ this._adapter.InsertCommand.CommandType = global::System.Data.CommandType.Text; \\ param = new global::Oracle.DataAccess.Client.OracleParameter(); \\ param.ParameterName = "ID"; \\ param.DbType = global::System.Data.DbType.Int32; \\ param.OracleDbType = global::Oracle.DataAccess.Client.OracleDbType.Int32; \\ param.Direction = global::System.Data.ParameterDirection.Output; \\ param.IsNullable = true; \\ param.SourceColumn = "ID"; \\ this._adapter.InsertCommand.Parameters.Add(param);
But no luck...

Unable to cast object of type OracleXmlType to type XmlDocument

Hello All:
I have an Oracle Procedure that is taking an XML Document as an output parameter.
oCommand.Parameters.Add("errorrecord", OracleDbType.XmlType).Value = System.DBNull.Value;
oCommand.Parameters["errorrecord"].Direction = System.Data.ParameterDirection.Output;
When I try to cast this as an XmlDocument so I can set it to my ErrorRecord variable (defined as XmlDocument) and pass it back out of the Web-Service
ErrorRecord = (XmlDocument)oCommand.Parameters["p_errorrecord"].Value;
I get the following error: "Unable to cast object of type 'Oracle.DataAccess.Types.OracleXmlType' to type 'System.Xml.XmlDocument'"
How do I cast / convert the Oracle XMLType back to a .Net XMLDocument to pass out of the function?
Thanks

No, I have not tried that yet, but I admit I don't fully understand the syntax in the document posted.
oCommand.Parameters.Add("p_errorrecord", OracleDbType.XmlType).Value = System.DBNull.Value;
ErrorRecord = GoCommand.Parameters["errorrecord"].Value; (this is returned as XmlType)
I don't quite understand the syntax in the posted URL:
Declaration
// C#
public XmlDocument GetXmlDocument();
How am I to use this to get the XMLDocument?

Hi Awen,
This kind of error usualy occur if we dont have enable proxytype for the CRM service.
Add the below line in your code after creating the service proxy and check :
_serviceProxy.EnableProxyTypes();

Unable to cast object of type 'FileStreamDeleteOnClose' to type 'System.IO.MemoryStream'

same code worked fine under Support Pack 8 (v. 13.0.8.1216).
When we upgraded to newest service pack 13, we started getting an error Unable to cast object of type 'FileStreamDeleteOnClose' to type 'System.IO.MemoryStream'
   Dim rpt   As New MemoryStream()
       Using ProfileRpt As New test.CrystalReport()
    ProfileRpt.SetDataSource(ds)
       rpt = DirectCast(ProfileRpt.ExportToStream(CrystalDecisions.Shared.ExportFormatType.PortableDocFormat), MemoryStream)

Same answer, we never supported MemoryStream, convert to IO.Stream then it should work.

Error message "Unable to load plug-in type"

Hi I used plugin registration tool and updated an existing plugin by a new dll.. and then afer that I started recieveing error messages on the CRM on our Dev environment. Error message "Unable to load plug-in type" it was registered for contact entity for
post create and update but we are getting this error on any entity updates and creates..
Any help on how to resolve this issue with be deeply appreciated.
thanks in advance,
Future MVP

While this thread is 3 years old, yet I just encountered the same problem about half an hour ago, and I believe this is a bug within CRM Solution Import routine.
What I had was a plugin which was imported previously. Then, I added new plugin steps and got 'Unable to load plugin type' when registering the new plugin steps I added.
The solution I have is:
a. Import just the plugin assembly without the new plugin steps, and publish.
b. The plugin assembly is now updated with the new plugin class definition. Then add the new plugin steps and import the solution again.
c. The solution should now be imported successfully.
What I believe the bug is CRM Solution Import routine checks for the plugin class/type definition in the existing plugin assembly in the server rather than the new plugin assembly in the solution being imported.
By the way, all solutions are unmanaged. Perhaps, the same bug will not happen in Managed solution.
HTH anyone else experiencing the same issue.
