Empty Website Data Source windown


Hi all,

I am Visual Web Developer user and facing a problem when I am creating a local report (.rdlc) file.

I am using Business objects as the Data Source for this report. It was working perfectly until all the items in the Website Data Source window suddenly "disappeared". The "Add New Data Source" button on this window is also disabled. Now the window is just like a blank box only. And I can't continue working with the report file like this...

I have tried undoing what I did before but it does not help at all...

Any reason for this to happen? There is no sign or something at least indicating what is wrong.

Please help.


 ps: found a similar thread in this forum but not solved

The report cannot be opened because the data source associated with it is not a report model.


i tried to open a report i created in sql business intelligence development studio in the report builder in wss3 and it gave me this error:

Microsoft.ReportingServices.ReportBuilder.ReportModel.Report: The report 'http://servername:port#/Reports/report.rdl' cannot be opened because the data source 'http://servername:port#/DataSource Library/datasource.rsds' associated with it is not a report model.

This report was not created in Report Builder. Try opening this report in Report Designer instead.

can i fix this so i can open my reports in report builder?

MDW Disk Usage for Database Report Error - A data source has not been supplied for the data source D

Hello, On the MDW Disk Usage Collection Set report, I get the following error when I click on a database hyperlink. A data source has not been supplied for the data source DS_TraceEvents SQL profiler shows the following SQL statements are executed (I've replaced the database name with databaseX) 1. exec sp_executesql N'SELECT dtb.name AS [Name] FROM master.sys.databases AS dtb WHERE (dtb.name=@_msparam_0)',N'@_msparam_0 nvarchar(4000)',@_msparam_0=N'databaseX' this returns zero rows as databaseX does not exist on my MDW central server, but is a database on a target server (i.e. one that is being monitored and uploaded into the MDW central server). 2. USE [datatbaseX] this produces the following error: Msg 911, Level 16, State 1, Line 1 Database 'databaseX' does not exist. Make sure that the name is entered correctly. why is the report looking for the database on my server? thanks Jag Environment: MDW (Management Data Warehouse) on SQL 2008 R2  

VS 2010 and data source issues

I've been banging my head against the wall for the past 4 hours on this one and think I'm going to need a little help here. I must be missing something. I'm in VS 2010 on Windows 7. I've got a web project which has been going fine, but no matter what I do I can't get a data source to show up in the Data Source window. I've added a data source using Data > Add New Data Source, and the "wizard" appeared to complete successfully. I have a data source showing in my solution explorer, and if I open the .xsd file I see all my tables from a remote SQL 2005 database. I have a good data connection to the database server showing up in the Server Explorer window. But no matter what I do I cannot get anything to appear in the Data Sources window, which is greyed out (the commands at the top are grayed out and there's gray text in the middle of the window reading "There are no data sources to show for the selected project"). Under the main Data menu at the top of VS, the "Show Data Sources" and "Add New Data Source" commands are missing. I can sometimes get them to reappear if I restart Visual Studio or reboot the OS, but not consistently. I've been all over Google on this and have tried every suggested solution I can find, to no avail. Anybody have any ideas? Thanks.

SslStream.Read() - Returns invalid data

Hey,I am currently attempting to implement a multi-threaded C# socket, using SSL (.pem file/certification/private key combo) server using Visual Studio C# Express.I have successfully made the client application establish a connection, and send data, which appears in plain, de-crypted text on the server - this works.However, I am 'polling' the socket to see if data is available to read.Here is some code which is appropriate:----        public void Process(int threadId)        {            int BytesRead = 0;            try            {                Master.Log("BEGIN READ");                sslStream.ReadTimeout = 5000;                BytesRead = sslStream.Read(bytes, 0, bytes.Length);                Master.Log("READ " + BytesRead + " bytes");                if ( BytesRead > 0 )                {                   // process                }             } catch (IOException e) {                Log("Caught IOException: " + e.Message);                if (e.InnerException != null)                    Log("=========> INNER IOException: " + e.InnerException.Message);         }---- Here is some console output when running the application:---------LOG: Authentication successfulLOG: BEGIN READLOG: READ 140 bytesLOG: [Thread 0] [Client 1] [Address] Client.ProcessDataReceived()Text received from client: Testing
