The ServiceBehavior transactiontimeout attribute was set to 00:10:00 (10 minutes) which overrided the inactivity timeout. We updated this setting and finally got success.
However, we definetely have to work on our database performance issues (probably due to some lacks in the design of deletion(cascade delete involved)). But that's another issue.
Oh welll...

I have a WinForms application that uses an assembly (v1) provided by a Third-party vendor. Now the vendor has released a newer version of the assembly (v2). The newer version is not available on all client machines, some still have only v1 installed while some have both v1 nd v2 installed.
How do I make my app load v2 of the assembly or fallback to v1 if v2 is not available. Assume that v2 is backward compatible with v1, i.e., the type names, contracts, etc, are the same.
Both these assemblies are installed into the GAC and I cannot use any private copies since they're very complex and have a lot of dependencies.
I tried using assembly redirection using application configuration file but that seems to be a permanent redirection. It does not check for existence of the assembly to redirect. So if I set redirection from v1 to v2 (and compile my app against v1), it always tried to load v2 and fails if v2 is not available. Similarly, if I set the redirection from v2 to v1 (and compile my app against v2), it always loads v1 even if v2 is available.
I tried using AppDomain.ResolveAssembly event, but using Assembly.Load inside the event handler keeps raising the ResolveAssembly event that results in a stack overflow.
Is there a better way to do it?
[SOLUTION]
I think I did the ResolveAssembly event in the wrong way. The ResolveAssmbly event is fired only when an Assembly load fails. I compiled my app against v2 and was trying to load v2 thru a Assembly.Load call (it also fails and fires a ResolveAssembly event leading to a Stack Overlfow). The correct way is to just load the v1 thru Assembly.Load and return it.

I'm now using EF 4.0，and I create a sample table named TableB,Table B‘s PK is (Id,YearMonth,Time),and column ClientId has been set as auto increased identity
when I Add a new record , Exception occrued And the full callstack is
System.Data.Mapping.Update.Internal.UpdateTranslator.ValidateRowsAffected(Int64 rowsAffected, UpdateCommand source)
System.Data.Mapping.Update.Internal.UpdateTranslator.Update(IEntityStateManager stateManager, IEntityAdapter adapter)
System.Data.EntityClient.EntityAdapter.Update(IEntityStateManager entityCache)
System.Data.Objects.ObjectContext.SaveChanges(SaveOptions options)
System.Data.Objects.ObjectContext.SaveChanges()
However,if I set the CientId column not as a identity column，every thing works fine
Can anyone tell me why this problem happens? thanks in advance

I have been facing some issues lately with Pinvoke calls to native functions of advapi32.dll from managed code and i haven't found yet a way to make it work properly, facing multiple problems related to the classic "A call to ... has unbalanced the stack" and "attempt to read/write protected memory".
My question here is regarding on how to debug those situations properly, as i may not have experience debugging this i ran into the situation where i cannot get information enough to know where the error is.
Is there any way to debug/step into those calls from VS2010 that im not aware of, or maybe a way to read the memory that is being allocated and try to discover it by myself?
To give an example, i have a PTR to a memory address which is supposed to hold a structure, which is pretty big and consist of a lot of another sub-structures and i believe the problem is related to the definition of those as i might not be using the correct data types.
So, for instance, how i can read a specific memory block from a PTR and see which data is allocated there to see if it fits into the structure in the correct fields?
I'm sorry if this is a confusion question, but I'm more like looking for some guidelines and tips into this... hope to get some comments.

Don't report your question. You've already posted this in the QA forum. Posting it again doesn't get you anything.
Besides, you haven't listed what you're trying to P/Invoke and the code you're using to try to call this stuff.
Listing ALL the tips and what to look for and how to do things would take more than a couple of forum posts.

1. stack problems are caused by using the wrong calling convention. Fix that first.
2. the easiest way to debug code in general is by adding log statements, and NOT by relying on fancy tools (which require boring interaction) or lots of MessageBoxes. That way you get a chronological and structured result, and you can see up to what point things go well.
3. the one way to debug P/Invoke stuff I know of, is by writing the code one piece at a time, starting with simple stuff, then adding to it. Which also means I provide some simple and some more complex dummy native functions, and get them to work first.
4. when in charge of both sides, keep your API simple; have the managed world do all the memory allocation; and use logging, also let the managed world log native information using a callback. I've explained that and more here[^].

This question would be better posted in the ASP.NET forum or referred back to paypal.

Hi,
Can anyone please let me know, how to kill the application session when the user clicks on the browser "X" button to close the browser.
I have googled and none of the examples seems to be working, appreciate a sample code.
Thanks,
Deb

|

If someone kills the browser, the server has no way of knowing. It just has to wait for the session to timeout.

You need one javascript function to capture browser unload event and one hidden server control button with click event. In that javascript function write code to click the hidden button. In the button click event you can do the actions you want like session clean up.
Ex:
//Javascript
javascript:window.onbeforeunload = function(){
if((window.event.clientX<0) ||
(window.event.clientY<0)){
if(document.getElementById("ctl00$testbutton")!=null)
document.getElementById("ctl00$testbutton").onclick();
}
}
//button event
protected void testbutton_ServerClick(object sender, EventArgs e)
{ Session["test"]=null;
Session.Abandon();
}
Hope it helps

The same thing could be accomplished with an AJAX call and avoiding another postback.
Also, using JQuery to find the DOM elements is more resilient than using getElementById, IMO.

Im trying to see if there is a better way of doing something that I have implemented. In our project we have a class that contains alot of generic list properties, for example
public class Portfolio
public property Client as list(of client)
end property
public property Covers as list(of covers)
end property
public property HomeQuotes as list(of HomeQuotes)
end property
end class
All the data is taken from the database using a LINQ to SQL. I have looked at using IoC container but am not sure that they are the best way to go as this container rarely changes in contents.
Any reference materials or that you could point me too or tips that you could give I would be grateful.

This really belongs into the ASP.NET forum and it should also contain code-formatting tags (see the link code above the editing textbox).

I am not .Net developer. I am just curious.
First of all, as far I understand .Net is suppose to be platform independent. That is why it compile targeting (I think I read somewhere) a Virtual processor.
Now if a developer use WIN32 API in there .Net Application will it be plat form independent at all? I believe no it wont be. Then what is the real purpose of developing a .Net application that would take too much memory, and make my old machine tired?

.NET is NOT platform independent. .NET is Microsofts implementation of the Common Language Infrastructure (CLI - which Microsoft wrote BTW) for Windows. Mono is another open source implementation of the CLI for Linux. General code that doesn't use any implementation specific libraries should work on any implementation.
When you start getting into the implementation specific stuff, like WPF in Windows, of course that's not going to work on Mono because Linux doesn't have WPF.
Any code you write that P/Invokes Win32 functions, obviously, will not work on anything other than a version of Windows that implements those functions.

No, it won't. Again, you seem to have some misconceptions on what .NET is and how it works.
