C# program is looking for sql server compact 3.5, but I'm using 4.0 -


OK, it really bothers me, and if I do not tell the title of the question correctly what is my problem Is it

I have a program built in C #, which is used by the entity framework and SQL Server CE. I have developed it on Windows 7, and it works fine. I have a Windows 8.1 machine on which I have tested it, and it also works fine on it

However, on some Windows 8.1 computers, the program crashes as soon as it reaches the database I try to get the following error:

Exception of non-tampering: system. Unknown Operation Exception: An entity framework provider, which was found with "System.Data.SqlServerCe.3.5" for the ADO.NET provider with an unchanged name. Ensure that the provider has been registered in the 'entry formwork' section of the application config file. See for more information.

Now, it really confuses me, because I have the latest NuGet package for SQL Server CE on my project (4.0). I used the SQL Server CE Toolbox to create a SQL Server CE 4.0 database explicitly, I distribute 4.0 DLL with the application, and I have explicitly found version 4.0 on the my app.config File ( invariantName = "System.Data.SqlServerCe.4.0" ).

So, why is the error called System.Data.SqlServerCe.3.5 ? Why this error is only on some Windows 8.1 machines?

(I have also searched through my complete solution, and the text "3.5" does not appear anywhere.)

I found such errors, and I used to include it Tried (from) to: 

  personal volatile type _ dependency; Public MyClass () {_dependency = typeof (System.Data.Entity.SqlServer.SqlProviderServices); }

It has no effect, I still get the same exact answer.

Anyway, if someone has any ideas, then I appreciate any kind of input.

I had a single problem and was resolved on its basis.

This section will be used by your App.config: 

  & lt; Runtime & gt; & Lt; Assembly binding xmlns = "karash: schema-microsoft-com: asm.v1" & gt; & Lt; DependentAssembly & gt; & Lt; Assembly ID name = "System.Data.SqlServerCe" publicKeyToken = "89845dcd8080cc91" culture = "neutral" /> & Lt; Compulsive redirects older version = "0.0.0.0-4.0.0.1" Newverson = "4.0.0.1" /> & Lt; / DependentAssembly & gt; & Lt; / AssemblyBinding & gt; & Lt; / Order & gt;

and older version = "0.0.0.0-4.0.0.1" to older version = "4.0.0.0-4.0.0.1" Change

sqlite3 - UPDATE a table from the SELECT of another one -

I have the first table article where some data is missing. In the table, articles_tmp I have a part of the missing data. So I want to update the articles. Where the path path is data in articles_tmp.path where the path is not zero . With SQLite , it does not work: update article SET path = (SELECT at.path FROM Articles_tmp as AS, WHERE at.article_id = a.id and a.asp, the text is in the form and not on. It has been transmitted) where the path is null MS Access Along with, it works fine: Update Articles Join the Inner Articles at articles_tmp articles.id = articles_tmp.id SETP articles.path = articles_tmp.path Can anyone help? Sin CE SQL Server Syntax, which I provided, was not working, here this solution With whom I have come. A little modification of your original query, but with my "correlation" suggestion added.

c# - Showing a SelectedItem's Property -

So I have enabled a rightclick option for my DataGrid. I want to display the only chosen property but it is not behaving like what I would like it to display my name and additional. Public category Paymentinfo {public int PaymentNo {get; Set; } Public string date {get; Set; } Public Double Pay {get; Set; } Public Double Principle {get; Set; } Public Double Interest {get; Set; } Public Double Balance {Received; Set; }} Private Zero MenuItem_OnClick (Object Sender, RoutedEventArgs e) {MessageBox.Show (AmortGrid.SelectedItem.ToString ()); } I'm trying to apply it without using a View Module! If I place a breakpoint where the messagebox and the recipient place it on selected ITEM, then this property will display the payment. A date-payment-principle-interest-balance is the only value that needs payment. Was hoping that it would be something like this MessageBox.Show (AmortGrid.SelectedItem.PaymentNo.ToString ()); When you call ToString () So you get the class typ

javascript - Render HTML after each iteration in loop -

I'm trying to gradually increase the font size of text on a web page. The code works in my place, although the new HTML / CSS does not render after every iteration of the loop and when all this is done, then display only the text of 100 px size.
