This the scenario have. There's an SSRS server that has a report where the datasource is of type XML and it uses windows authentication, nothing else to it. Inside the report there's a dataset that uses that data source with this for a query "=Code.ReportUser.GetListOfItems()". This calls a method in the custom assembly that connects to the database and returns data in a string formated like this (angle brackets changed to curly for read
"<Query><XmlData><Items>" + xmlDocument.DocumentElement.InnerXml + "</Items></XmlData></Query>"
where sql datatable is written into the xmlDocument. If I go to the reporting server through an IE and run the report everything works as it should. The Problem occures when add this link to Zangle application which runs it as "IEHOST.app 'report's url'". I believe its a foxpro app that opens a browser object and report fails on the dataset that uses my xml data source. There's no question about url or reports correctness because it functions in a different environment.
This is the server error i get:

I'm not sure what this means exactly. Any thoughts? it looks like a permission issue but i don't understand where. I did try to change xml data source authentication from windows to none and then add my AD account as an execution user on the reporting server. This didnt' change anything still working from browser but from Zangle browser object. One more thing, server requires authentication and all the report regardless of the environment promt for login and successfully authenticate so my credentials seems to pass to the server and only my xml data source is throwing an error when launched from with Zangle. Please share your ideas. I'm a programmer but I'm not too server stuff savy and I'm new to SSRS. Thank you.
Resolved. Turns out that foxpro app lowercases everything and the name of the sql server passed to the assembly doesn't match the name stored in the assembly. Silly :) So we'll be lowercase comparing everything from now on.

From topic,
I have a receive location that currently uses sql adapter(receive port) to call(poll?) a stored procedure. The stored proc returns a FOR XML result.
The receiver then activates an orchestration which takes the message and populate the data from the message and into some variables (expression shape).
Orchestration looks like:
LongScope[ AtomicScope[ Receive location -> Expression ] ][Error handling]
I tried a direct migration to wcf-sql with XMLpolling as InboundOperationType, but it throws a null exception during the variable assignation(I assume).
Additional detail:
I caught the message from the receiver by filtering pipelineName using a send port. There is a slight different in the message retrieved by sql and wcf-sql adapter
sql:
<rootNode xmlns="namespace"><row data1="data1" data2 = "data2" /></rootnode>
wcf-sql:
<rootNode xmlns="namespace"><row data1="data1" data2 = "data2" xmlns=""/></rootnode>
Which should do nothing, if this msdn post is correct
I also went into orchestration debugger. Weird thing is, when using sql adapter, the message is still = null, but the varibles are assigned without problem. I also tried adding a send port directly after the receive port to dump the message. Nothing came out
I would appreciate any info/suggestion/solution
Do tell me if im missing any info.
Irrelevant Info:
As of this post the receive port doesnt even trigger anymore. I dont know why. Rebooting PC.
Also I suspect Biztalk gave my bruxism and lead to me requiring 6 teeth fillings
The difference between XML in SQL en WCF-SQL has nothing to do with the MSDN post you are linking to.
In the 2nd XML (WCF-SQL adapter), the row node does not have a namespace. In the 1st XML (SQL adapter), the row node inherits the default namespace "namespace" from its parent: 'root'.
Regarding the Receive Port not triggering anymore:
Are you sure your Host Instance(s) are still running?
My solution:
I added "xmlns = 'namespace'" as a 'data' in the stored procedure.
The adapter recognized it and removed it(since it was the same as parent node), allowing me to use the old schema.
Filler:
So I generated a schema using the output from WCF-SQL adapter,
however I couldnt replace my old one with it, since the expression shape will not recognize its child elements (var = messageObject.childElement)
I created a map to map the new one back to the old one.
But that didnt work, because they both shared the same namespace, and biztalk complained during runtime that it couldnt decide which schema to use.
I have created share point data access layer with spmetal, everything is works fine but when I try to query with task summary list through SPMETAL it throws error I tried several techniques to cast , directly use this Iqueryable list but as I try to access it, "it throws error specified cast is not valid"
Any help or clue why is throwing this error
Its solved by changing the types of event type to string and duration field with double .
that error was produced by SPMETAL wrong mapping while generating the layer form SharePoint.
I am unable to write any records to my database using a web service. Service is set up OK and can access it via uri and also query my database via the service using a simple page i created.
When it comes to writing to the database, I am not getting any errors, and the instance of my WebClient which is populated with variables to write to the db is holding all the variables OK but when it comes to actually writing to the db (see below code) nothing seems to happen except that the Member ID of the last existing member added to the database is returned.
'assign all abMem fields to values within form to write to database
newMem.Title = ddTitle.SelectedValue
newMem.Initials = txtInitials.Text
newMem.Surname = txtSurname.Text
newMem.Address1 = txtAdd1.Text
newMem.Address2 = txtAdd2.Text
newMem.Address3 = txtAdd3.Text
'etc etc .... additional fields have been removed
Try
cc.Open()
cc.CreateMember(newMem)
returnMem = cc.GetMember(newMem)
MesgBox(returnMem.MemberID & " - Member Created")
cc.Close()
Catch cex As CommunicationException
MesgBox("CommEX - " & cex.Message)
cc.Abort()
Catch tex As TimeoutException
MesgBox("TimeEX - " & tex.Message)
cc.Abort()
Finally
MesgBox("Closed the Client")
End Try
When i run the above, I've noticed in the log file for the service (in the system32 folder on my server) that 2 requests are made each time - presumably one for where I am trying to add a record and the other I would think would be the request for the ID of this member (which isn't created, hence why I believe it it is simply returning the last successful entry in the table).
I know there isn't a problem with the actual web service as there is another user successfully able to add to the db via the service (unfortunately I am unable to simply copy their set-up as they are hitting it via a php page) so i know there is a problem somewhere in my code.
Is cc.CreateMember(newMem) the correct syntax for passing a member's details to the function in the webservice is what I am wondering?
I've re-wrote the code (seems identical to above) and republished the web service. Seems to be working OK now so I must have had some silly mistake somewhere!
I just started working with an application that I inherited from someone else and I'm having some issues. The application is written in C# and runs in VS2010 against the 3.5 framework. I can't run the application on my machine to debug because it will not recognize the way they referenced their parameters when writing their DB queries.
For instance wherever they have a SQL or DB2 query it is written like this:
using (SqlCommand command = new SqlCommand(
"SELECT Field1 FROM Table1 WHERE FieldID=#FieldID", SQLconnection))
{
command.Parameters.AddWithValue("FieldID", 10000);
SqlDataReader reader = command.ExecuteReader();
...
If you will notice the "parameters.AddWithValue("FieldID", 10000);" statement does not include the "#" symbol from the original command text. When I run it on my machine I get an error message stating that the parameter "FieldID" could not be found.
I change this line:
command.Parameters.AddWithValue("FieldID", 10000);
To this:
command.Parameters.AddWithValue("#FieldID", 10000);
And all is well... until it hits the next SQL call and bombs out with the same error. Obviously this must be a setting within visual studio, but I can't find anything about it on the internet. Half the examples for SQL parameter addition are written including the "#" and the other half do not include it. Most likely I just don't know what to search for.
Last choice is to change every query over to use the "#" at the front of the parameter name, but this is the transportation and operations application used to manage the corporation's shipments and literally has thousands of parameters. Hard to explain the ROI on your project when the answer to the director's question "How's progress?" happens to be "I've been hard at it for a week and I've almost started."
Has anyone run into this problem, or do you know how to turn this setting off so it can resolve the parameter names without the "#"?
Success! System.Data is automatically imported whenever you create a .NET solution. I removed this reference and added it back to make sure that I had the latest version of this library and that fixed the issue. I must have had an old version of this library that was originally pulled in... only thing I can figure.
Its handled by the .NET Framework data providers not Visual Studio.
It depends on the data source. Look here:Working with Parameter Placeholders
You can try working with System.Data.Odbc provider and using the question mark (?) place holder. In thios case dont forget to add the parameters in the same order they are in the query.
we've got a real confusing problem. We're trying to test an SQL Bulk Load using a little app we've written that passes in the datafile XML, the schema, and the SQL database connection string.
It's a very straight-forward app, here's the main part of the code:
SQLXMLBULKLOADLib.SQLXMLBulkLoad4Class objBL = new SQLXMLBULKLOADLib.SQLXMLBulkLoad4Class();
objBL.ConnectionString = "provider=sqloledb;Data Source=SERVER\\SERVER; Database=Main;User Id=Username;Password=password;";
objBL.BulkLoad = true;
objBL.CheckConstraints = true;
objBL.ErrorLogFile = "error.xml";
objBL.KeepIdentity = false;
objBL.Execute("schema.xml", "data.xml");
As you can see, it's very simple but we're getting the following error from the library we're passing this stuff to: Interop.SQLXMLBULKLOADLib.dll.
The message reads:
Failure: Attempted to read or write protected memory. This is often an indication that other memory has been corrupted
We have no idea what's causing it or what it even means.
Before this we first had an error because SQLXML4.0 wasn't installed, so that was easy to fix. Then there was an error because it couldn't connect to the database (wrong connection string) - fixed. Now there's this and we are just baffled.
Thanks for any help. We're really scratching our heads!
I am not familiar with this particular utility (Interop.SQLXMLBULKLOADLib.dll), but have you checked that your XML validates to its schema .xsd file? Perhaps the dll could have issues with loading the xml data file into memory structures if it is invalid?
I try to understand your problem ,but i have more doubt in that,
If u have time try access the below link ,i think it will definitely useful for you

I know I did something that raised this error message once, but (as often happens) the problem ended up having nothing to do with the error message. Not much help, alas.
Some troubleshooting ideas: try to determine the actual SQL command being generated and submitted by the application to SQL Server (SQL Profiler should help here), and run it as "close" to the database as possible--from within SSMS, using SQLCMD, direct BCP call, whatever is appropriate. Detailing all tests you make and the results you get may help.
