Develop Mobile and Embedded apps with Microsoft SQL Server Compact 4.0

Microsoft SQL Server Compact is an embedded(able) database ideal for desktop, (hand-held) mobile devices and web clients. It is free to download (also free to deploy and redistribute) and comes in the form of just one code-free file. Its small foot print makes it easy to  deploy to a variety of device sizes and requires no administration. It also supports a subset of T-SQL and a rich set of data types.

The latest version in Version 4.0.8482.1 and you can download from here:
https://www.microsoft.com/en-us/download/details.aspx?id=17876

New features in SQL Server Compact 4.0 (per Microsoft site):

  • SQL Server Compact 4.0 is the default database for Microsoft WebMatrix, which is a stack of web technologies for easily building and deploying websites on the Windows platform.
  • For enhanced development and debugging capabilities, including designer support, Visual Studio can be used to develop ASP.NET web applications and websites using SQL Server Compact 4.0.
  • Enabled to work in the medium or partial trust environments in the web servers, and can be easily deployed along with the website to the third party website hosting service providers.
  • Private deployment of SQL Server Compact further simplified by having all the required managed assemblies, and the x86 and x64 DLLs, including the Visual C++ 2008 runtime libraries (x86 and x64) SP1 in a single private folder in the install location of SQL Server Compact.
  • Stronger data security with the use of the SHA2 encryption algorithms for encrypting the databases.
  • T-SQL syntax enhancement by adding support for OFFSET and FETCH that can be used to write paging queries and new APIs like SqlCeConnection.GetSchema that provides the metadata information of the database.
  • Used with ADO.NET Entity Framework, SQL Server Compact now supports the columns that have server generated keys like identity, rowguid etc. and the code-first programming model.

    These article provides sufficient information for the previous version and some starting points:

Blogger has a problem with the html tag 'pre'

For quite sometime I have had problem displaying HTML code in my blog as the Pre tag did not render correctly. Here I am trying to see what is happening, if any in rendering the Pre tag. I decided to show only screen shots of either the HTML tab in my blog post, or the Compose tabbed page of my blog so that the browser effects are properly seen.

When you want to create a new post in Blogger, this is the HTML code you get and the 'Compose' page is empty.


Pre_00
Now I enter a single line-'This is a test' in the Compose tabbed page.

Pre_01

The HTML markup shows this:


Pre_02

Now I add a 'Pre' tag as shown.


Pre_03

The following is the content of the 'Compose' page.

Pre_04
So far no problem, good.

I now go back to HTML pane. Looks OK, but it has added another repeating line at the top.


Pre_05

Not a big difference. I refresh the browser and everything back to as it was before refresh.
I just draw a line in 'Compose'.


Pre_06

The HTML after this appears as shown. It has added 'Pre' tags as shown. Why 'pre' tags which not just 'p'.

Pre_07

I just added a 'div' tag and I am going to place a 'Pre' tag inside the 'div' tag.


Pre_08

This is the 'compose' page.

Pre_09

I added some 'pre tag' inside the div tag


Pre_10
The compose  now appears as shown.

Pre_11
I add another div and within div I add a pre tag. In the pre tag I add special characters (HTML markup) as shown.


Pre_12

The Compose page after the above appears as shown.

Pre_13

The pre tag did not work as intended for html tags.
I revert to the HTML to see if the blogger's processor has added any thing by itself. It does some time. No change.


Pre-14
I add a dotted line in HTML code.


Pre_15

There is an expected change as shown.


Pre_16

I revert to HTML and I see it has changed.


Pre_17
This time it accommodated the dotted line inside the 'div'. I modify the page with 'code' tags as shown. Some recommendation from some of the Internet sites is to enclose it in 'code'


Pre_18

The 'Compose' page now appear as shown.
The extra > in the last line appears to be an error while typing.
 Page_19

It is getting worse!

I refresh the page and nothing is changed in 'Compose'.

I host the html page on the local IIS Server and the response is as shown.


Page_20

The conclusion is  'Pre' tag is not working in the Blogger as it is supposed to.
