c# - WCF, channel factory, and exceptions -


Using VS2008, vb.net, C #, FW 3.5

I'm your customer I am going to take my service

service went hosted in IIS

using client (WiFi form MDI) / L / R / CT, and sv. / N switch

service and customer access to both a MyEntities.dll

I nettcp I'm using mainly the proxy cache with TransportWithMessageCredential 

  If Membership.ValidateUser (UsernameTextBox.Text, PasswordTextBox.Text) _proxy = new MyServiceClient _proxy.ClientCredentials.UserName.UserName = "username" _proxy.ClientCredentials.UserName.Password = "password"
< p> I have any prior use of its child forms / plugin 

  list (needs orders) = _proxy.ChannelFactory.CreateChannel.GetOrders (client) that   
 Everything is working very well but my questions are: 
 
 What happens to the channels after the call? Are they disposed magically? 
 
 How can I see it, with a professor? 
 
 Is there a way that I can control the error in one place or do I try / get caught in every call like 
 
  try {... client Close (); } Hold (communication exception e) {... client.Abort (); } Hold (Timeout Exception E) {... client.Abort (); } Hold (exception e) {... client.Abort (); throw; }  
 
 I can subscribe to _proxy.InnerChannel.Faulted and clean that there? 
 
 Depending on Regards

Use Cases I used to do two different things:

  • The client scenario, where I know that once only one instance of the channel is used, I make the lazy-one channel , And use the built-in example again. If this is a mistake, is closed or disposed, then the channel has been rebuilt.
  • In a scenario where multiple channels can be requested at the same time, I think it is best to perform exception handling dancing. To save the order code, it is a way of realizing that it accepts a representative to do this work so that he can center around your payload code once in write-outs exclamation form .

sql - dynamically varied number of conditions in the 'where' statement using LINQ -

I am using my first project LINQ (in mvc), so maybe there's something very simple that I remember. However, a day of searching and experimenting does not work, so it works. I am trying to write a LINQ query (Linux to SQL) in which in many cases where the statement is different from an OR or an AND. We do not know how many conditions are going in the query till runtime. This search is for filter control, where the user can choose multiple criteria for filtering. Select from table where table.col = 1 or table.col = 2 or table.col = 7 .... 'Other number of conditions Before I just create the SQL query as a string, while looping over all the situations. However, it seems that there should be a good way to do this in LINQ. I tried to use Expression trees, but they had a second thought for this moment on my head, where the lambda function was to be executed inside the statement such as: values ​​for matchingRows = matchingRows for each value Where (function (row) row.c...

asp.net mvc - Dynamically Generated Ajax.BeginForm -

I have a problem with ASP.NET MVC Ajax forms. I generate many Ajax form in a table such as: & Lt; Input type = "submit" name = "activity" value = "add activity" / & gt; & Lt;%}% & gt; & Lt; / TD & gt; & Lt; / TR & gt; & Lt;%}% & gt; So far so good. When I post one of those forms, it gives a partial view in a div, and in this new partial view a new Ajax Beginnform (which is not in Genesis form) This second Ajax Beginnorf is exactly like the ones I got on the table, but when I post it, I do not get the "Ajax Post", but a normal post that sends me to a new page, I do not know whether the two Ajax forms What is the reason for the difference between, why is it the "dynamically generated" Ajax form behaves like a normal HTML form? By the way, I know that I can do it in different ways using javascript, but I would like to understand whether it can only be done using MVC helplars and Ajax lib...
