EF will see a .NET type of DateTime in your POCO and use the native DateTime datatype specified by the underlying data provider. It will not convert a DateTime to a "serial number" as you want because the serial number can be based on any arbitrary epoch. For example, UNIX uses 1/1/1970 00:00:00AM whereas .NET uses 1/1/0001 00:00:00AM. So, to each system, the datetime serial number will mean something different.
Why even do this?? Why not just let the underlying database handle the storage and return the correct datetime without your code having to worry about conversion?
Please, I really need a help.
Everytime I try to launch every Kinect application, VS 2010 indicates me that there is a problem with the Runtime in Microsoft.Research.Kinect.
Everytime, I get this :
"Impossible de charger le fichier ou l'assembly 'INuiInstanceHelper, Version=22.214.171.124, Culture=neutral, PublicKeyToken=31bf3856ad364e35' ou une de ses dépendances. Le fichier spécifié est introuvable."
Please, can you tell me what's wrong and what I have to do.
It means that it cannot find the assembly named in the message, or some other assembly that INuiInstanceHelper depends on. Check that you have the correct version of .NET installed and any third party products that are needed.

I use WEB GUI form. Can you show me any type solution? Thank you
Hello guys. Working in C# when you collapse a function, only the functions signature remains visible while the rest of the function body changes into boxed ellipsis. The color of this ellipsis also changes accoring to the settings. Again, the color of the boxed ellipsis changes only. It looks something like this
int Function() ...
I want the same in VB.Net. Although the function signature remains visible but unlike CSharp, color of the whole function signature changes in VB.Net. At the very least, I don't feel comfortable with this.
I hope you got my problem. If so, is there a way to make this behavior similar to that of CSharp? Thanks for any suggestions.

I think my question was not clear enough. I exactly did what you suggested, before posting this question.
I also wrote that the whole function signature changes its color.
However in CSharp, only he boxed ellipsis changes its color. The function signature retains its color scheme.
So is there anyway in VB.Net, adopt this CSharp behavior in VB.Net. I googled it but could not find any.

This is nothing to do with C# or VB, it is a Visual Studio issue, and these changes can only be made through the options settings. If VS does not offer a specific option to do what you want then you need to petition Microsoft for the change.
It may appear that the same code editor is being used when you look at C# and VB.NET, but it's not. The C# and VB.NET code editors were written by different teams at MS and the functionality difference between the two are quite extensive.
Part of the reason for these differences is maintaining a "feel" that appeared in previous products. The C# code editor "feels" more like the editors of C/C++ of Visual Studios past, while VB.NET "feels" and works more like the old VB6 and below editors.

I am an electronics engineer by profession. I have programmed in C and C++ and therefore mostly understand about object oriented programming and classes.
However, I have downloaded a program, from "the code project", that is written in C# for the asp.net framework. It implements "The Rectangle Packing Algorithm".
I do need to rearrange parts of this program in order to suit my needs. It was written by a professional web developer. I have loaded the program in visual studio and it does run.
I have tried to make heads or tails out of the program by reading books about C# and asp.net but the process is rather slow and I do have a life. I can now "get around" in simple c# but this program is still way above me as I can't make heads or tails out of the way that the C# is making use of the asp.net framework.
I would learn a lot faster if I knew someone that was capable of looking at the program and saying "here is what is going on here and there, etc". It is not a matter of asking a simple question, say, about classes or constructors, etc.
At my company there are only C, C++ and embedded programmers who claim no knowledge of c# or asp.net.
I am even amenable to paying someone for their services, through PayPal.
ASP.NET is not the same as .NET, their applications run in a web browser, they are not desktop applications. You could always post a question in the forum at the end of the article and see if the author can offer any further information that would help you.
I just recently upgrade to VS2012 and I'm a little confused reading about the new .NET CF 3.9 so I'm hoping someone here can clear up my confusion.
Back when I was using VS2008 I wrote some software for my company. The software ran on a HP iPAQ PDA and was a data entry software. When VS2010 came out it no longer supported the .NET CF but now I'm reading that VS2012 will support a new version of the CF (3.9) starting Q1 2013. When I search on Microsoft's site though I see links saying "Evaluate Compact 7 for free today." Back when I wrote the iPAQ software everything was free. Visual Studion had a project type for mobile devices and the .NET CF was a free install. Now it looks like to write anything for a mobile device it is an extra fee.
Am I missing something? Is the Compact 7 different then the .NET CF 3.9? Is there any installs to add a mobile device project type to VS2012?
I know it would be easier if my company just upgrade our devices but they don't want to spend the money when the HP iPAQ are still functioning. I would like to update the software on it, I just hate having to work on the PDA software with VS2008 and then the companion desktop application with VS2012.
In the meantime, is there anyway I could currently work on the PDA application with VS2012?
I am trying to merge to byte arrays and can't seem to get my code to work. Code below. Can i get some thoughts on what might be happening? I have verified that the arrays DO have data in them(aka length > 0).
Dim pdfBytesSyllabus AsByte() = pdf.GetPdfBytesFromHtmlStream(streamSyllabus, System.Text.Encoding.ASCII)
Dim pdfBytesCenter AsByte() = pdf.GetPdfBytesFromHtmlStream(streamCenter, System.Text.Encoding.ASCII)
Array.Copy(pdfBytesCenter, 0, pdfBytesSyllabus, pdfBytesSyllabus.Length, pdfBytesCenter.Length)
Array.Copy won't work as it does not resize the destination array (pdfBytesSyllabus) to hold the additional data from pdfBytesCenter.
The steps required are
1) Create a new array of sufficient length to hold both arrays
2) Copy pdfBytesSyllabus to the new array at index 0
3) Copy pdfBytesCenter to the new array at index pdfBytesSyllabus.Length
Much the same thing could be done with a generic List Of Byte, which is really just an implementation of a resizable array with a lot of useful methods added.
