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 127.0.0.1] Client.ProcessDataReceived()Text received from client: Testing

the error occours when i try to run the code FlushFinalBlock();

here is my code:

Invalid Model Data Base. Requires Version:3 but has Version: 0

  

Hi everyone…  I interpreted and installation manual wrongly.  So I assume that a needed to remove and re-install my SQL server 2005. The manual clearly mention that it will be a good Idea to back up my files. I follow the manual instructions and backed up all the files … 4 totals.

Re-install the SQL server 2005 and all working just find. After the installation I try to restore by backup files. Its looks like it does It and suddenly I got and error message. 

“unable to login user to database with the EXECUTE permission was denied on the object ‘p_CreateSeccion’, database ‘422-chaff’, schema ‘dbo’.”

Well this I have check the size of the mdf and ldf files and they are the same as my previous files ( notice that I have a complete copy of the folder where the SQL used to be install, So I have all the old files) but if I try to load the data file it show this error message.

“invalid model database. Requires Version: 3 but has Version:0”

I call the office from the guys how made the software I’m using and they will need to research it, they say is a version issue saying that my backup files have a newer version that my SQL server or something like this.

Does someone know how to fix this or upgrade, downgrad

Binding WPF Controls to an Entity Data Model

Surrogate vs Natural Primary Keys - Data Modeling Mistake 2 of 10

  
In case you're new to the series I've compiled a list of ten data modeling mistakes that I see over and over that I'm tackling one by one. I'll be speaking about these topics at the upcoming IASA conference in October, so I'm hoping to generate some discussion to at least confirm I have well founded arguments.

The last post in this series Referential Integrity was probably less controversial than this one. After all, who can argue against enforcing referential integrity? But as obvious as surrogate keys may be to some, there is a good deal of diversity of opinion as evidenced by the fact that people continue to not use them.

Editing the Data in a GridView

  
In addition to deleting a GridView's underlying data, another common need is to allow end users to edit the data displayed in a GridView. With ASP.NET 1.x's DataGrid control, editing the data is certainly possible, but requires creating three event handlers and writing a dozen or so lines of code. With the GridView and ASP.NET 2.0, it is possible to create an editable GridView without writing a single line of code! All of the necessary functionality is encapsulated within the GridView.

The GridView allows editing on a row-by-row basis. An editable GridView contains an additional column with an Edit button in each row. When the end user clicks on an Edit button that row becomes editable, causing the Edit button to change to Update and Cancel buttons and the other columns to become TextBoxes. The end user can then update one or more column values and click Update to save their changes.

Using ASP.NET 3.5's ListView and DataPager Controls: Displaying Data with the ListView

  
Prior to ASP.NET 3.5, developers who needed to display a set of records could choose between the GridView, DataList, and Repeater controls. The GridView provides rich data features, but has a very boxy layout; the DataList and Repeater allow for a more flexible layout, but lack the "point and click" data features found in the GridView, DetailsView, and FormView controls. The ListView bridges the gap between layout flexibility and built-in data features.

This article, the first in a series of articles on the ListView and DataPager controls, looks at the ListView's many available templates and illustrates how to display data. Read on to learn more!

Dynamic Data Templates in GridView ASP.NET 3.5

  
At a high level, Dynamic Data Templates can be seen as a system to very quickly build up a User Interface linked with the relevant data model, immediately enabling you to perform CRUD operations (Create, Read, Update, Delete) on the database using the specified data source. They provide a powerful method for building up these kinds of applications, and I'm going to focus on an overview of what Dynamic Data Templates actually are, and a few ways of customizing them to suit industry needs.

MS SQL Server: Search All Tables, Columns & Rows For Data or Keyword Query

  
If you need to search your entire database for specific data, this query will come in handy.

So when a client needs a custom report or some sort of custom development using Great Plains, most of the time I will have to track down the data in the system by running this query and find the table(s) it is in.

Displaying Data using ASP.NET 2.0 Repeater and C#

  
This tutorial will show you how to display data using the .NET Repeater Control, ASP.NET 2.0 and C#.NET


The Repeater control is a powerful tool and is easy to use.

First, you will need to import the System.Data.SqlClient namespace.
