The object context provides a Refresh method that you can call to bring entities back into sync with the current state of the rows they represent in the database. You could call this after catching an OptimisticConcurrencyException as the first step in your code that recovers from a problem. (You re not actually required to wait until you get a concurrency exception you re free to call Refresh at any time.) The first argument to Refresh tells it what you d like to happen if the database and entity are out of sync. Passing RefreshMode.StoreWins tells the EF that you want the entity to reflect what s currently in the database, even if that means discarding updates previously made in memory to the entity. Or you can pass RefreshMode.ClientWins, in which case any changes in the entity remain present in memory. The changes will not be written back to the database until you next call SaveChanges. So the significance of calling Refresh in ClientWins mode is that you have, in effect, acknowledged changes to the underlying database if changes in the database were previously causing SaveChanges to throw an OptimisticConcurrencyException, calling SaveChanges again after the Refresh will not throw again (unless the database changes again in between the call to Refresh and the second SaveChanges). rdlc qr code How to generate QRCode in RDLC report using C# and VB.Net in ASP ...

Choose the Branch1Condition for Branch1 Perform the same steps on the right branch with a name of Branch2 and Branch2Condition Now the IfElse activities are all set up to evaluate which branch to follow The next step is to tell each branch what to do when it s evaluated as True Add a SetState activity to each branch with a name of SetStateBranch1 and SetStateBranch2, and change the TargetState to the appropriate state, either Branch1State or Branch2State The composite FirstState activity should look like Figure 3-3.. Executing the same LINQ query multiple times against the same context will still result in multiple queries being sent to the database. Those queries will typically return all the current data for the relevant entity. But the EF will look at primary keys in the query results, and if they correspond to entities it has already loaded, it just returns those existing entities and won t notice if their values in the database have changed. It looks for changes only when you call either SaveChanges or Refresh. rdlc qr code NET RDLC Reports QR Code Barcode Generator - BarcodeLib.com

Using free RDLC Report Barcode Generator Component SDK to create, print and insert QR Code barcode images in Visual Studio for RDLC Report. This raises the question of how long you should keep an object context around. The more entities you ask it for, the more objects it ll hang on to. Even when your code has finished using a particular entity object, the .NET Framework s garbage collector won t be able to reclaim the memory it uses for as long as the object context remains alive, because the object context keeps hold of the entity in case it needs to return it again in a later query. That will redirect the output into the file called rndc.conf. Open the rndc.conf file using a text editor such as GEdit and browse the contents. The contents may look like Listing 11-6. Listing 11-6. The Configuration Files for rndc and named # Start of rndc.conf key "rndckey" { algorithm hmac-md5; secret "9mt/YqgRTHjiA2H924sfyg=="; }; options { default-key "rndckey"; default-server 127.0.0.1; default-port 953; }; # End of rndc.conf # # # # # # # # # # # Use with the following in named.conf, adjusting the allow list as needed: key "rndckey" { algorithm hmac-md5; secret "9mt/YqgRTHjiA2H924sfyg=="; }; controls { inet 127.0.0.1 port 953 allow { 127.0.0.1; } keys { "rndckey"; }; }; End of named.conf The way to get the object context to let go of everything is to call Dispose. This is why all of the examples that show the creation of an object context do so in a using statement. rdlc qr code How to Generate QR Code in RDLC Report using C#
