entity framework 5 - EF5 and Ado.Net -

-

I have an existing code that uses Ado.Net and I'm trying to integrate some new code Which uses the Entity Framework 5. For the concept as a proof, I wanted to try a transacted operation with both ado.net and EF5.

I tried to use the transaction skip but as I was using "two connections", I got an error about the promotion of the transaction and DTC is available.

Can I use the same connection to Edonate and EF5 to avoid the above problem? If so, any code example ....

Any other suggestion appreciated.

BTW, I am using the EF5 database first.

Thanks for advance help.

Regards, Travis

Yes, but only if you have a distributed transaction Coordinator (DTC) configured DTC transaction is very slow with local transactions.

This can help:

Another option is to obtain the EntityConnection object and obtain SqlConnection and use it in your ADO. Net command, but you have to be careful about it because if the inserted unit is settled, the connection can be closed.

Or when you make it, you can pass an EntityConnection in the context, so the only one connection used for both.

excel vba - How to delete Solver(SOLVER.XLAM) code -

-
After opening several examples of macro / code written, I suddenly get stuck with a code that seems safe. Solver (SOLVER.XLAM) is doing this notation and I would like to remove it from my system. I do not think this is a relativant code. Can anyone tell me what should I do? I have already installed something to remove the password but Solver is still asking for password and I can not get rid of it! itemprop = "text"> Solver Excel is add-in If you want to delete it, then Excel Application & gt; Options & gt; Add-ins & gt; Search for 'Go to' button and gt; Uncheck the solver on the list like press something (I can not give you the exact path because I have the Polish version of Excel). Trying to open Solver's VBA code is not good because it There is allegedly copyright. Besides, I do not think Solver creates any disadvantages while working with Excel or VBA.

I am using a Google line chart on my page, which refreshes every 5 seconds but weird thing It is that every refresh chart causes the line to be removed, although the size of the chart remains the same.

I am using a documentListener to read from my betterJTextFields in real-time, I have the problem that insertUpdate (DocumentEvent e) . I need to reach Better Zest Field that happened to DocumentEvent . For example, if invalid input, would be better zestfield turn red etc. I have all my better zestfield in the matrix if you should know.
