Hi,
I've got an object that is serializable. It implements the IDeserializationCallback interface, to perform some additional work after it's been deserialized.
It works fine if I use a SoapFormatter to serialize/deserialize the object, but if I pass the object to a WebMethod, the OnDeserialization method never gets called. I'm obviously incorrect in assuming that WebMethods use SoapSerialization to pass objects.
Is there any way I can get a post deserialization method of some kind to be called after the WebMethod has finished deserializing the object?
Can anyone help?
Thanks

Hello. Is it possible to use SQL Server 2000 Notification Services together with .NET 2.0 client. Thanks in advance.
|
|
|
|
|
Yes it is.
.Net 2.0 connects to sql 2000 or sql 2005 without even changing a line of code. As SQL Server 2000 Notification Services is part of Sql 2000 and primarily watches for table updates you can use it without problems. I have been working on a big project that migrated from .Net 1.1 to .Net 2.0 a year ago, but we only moved up to SQL 2005 six months ago, primarily because nofification services is much better integrated with SQL in 2005.
If you have knowledge, let others light their candles at it.

Thank's a lot for your answer. There's too little information on this topic in internet and I'm just a beginner in notification services.

Hi all,
Actually i was looking for automatic background process to deliver mails if certain condition met in database so i posted a question last week and i received suggestion to create Windows services to do it.
Unfortunatly I never worked with windows services so i created a small service and installed it without any trouble. But i am not able to start it. When am trying to start its giving be alert box saying "This service has been started and stopped. Some service stop automatically if they have no work to do."
But i have created the service with timer to trigger every 30 sec to write an entry to a database table.
Looks like i cannot start the service at all. Also i tried to debug it but i could not find my service.exe in the list to attach since it is not running. {instead i found explorer.exe which is new and from the same path my service.exe exists. But physically explorer.exe is not existing in that folder)
please some one help me in fixing this. Am i missing something?
Thanks in advance

There is a few registry flags that controls how services are run. One of these options, I think, is to have the service run in its own process or as part of a system process (cant remember which one). If the service is set to run as part of this system process it will be loaded with LoadLibrary() and executed on a thread of this system service. I think thats why you cant see it. Search around for details of the registry entries assosiated with a service.
For debugging I always used __asm{int 3} in c++ to break into the debugger but you probably cant do that in .Net
Why dont you put something in your init routine that will cause an exception. Then windows will show you the unhandled exception dialog and give you the option to debug the process
Generally I think it is easier to develop your app as an exe and then convert it into a service once its all debuged and running.

It sounds like your Main routine is simply returning without registering with the service control manager (not calling System.ServiceProcess.ServiceBase.Run) or that the service's OnStart method is simply quitting. I can see that a working service we have here is creating a new thread in OnStart to do its work. This is virtually required because the OnStart method is expected to return back to the SCM fairly quickly - otherwise the control application will report that the service failed to start.
To debug service startup, we add the following to the top of Main:
#if DEBUG
System.Diagnostics.Debugger.Launch();
#endifThis causes the Just-in-Time debugging window to appear, asking you which instance/version of VS you want to debug with.

Hi,
You are 100% correct. The problem was service's OnStart was simply quiting without doing anything. So i created a new thread in Onstart and it does solved the problem. The service is running without any trouble. Also since it is running i can locate it in running process list to attach to debug.
Your suggestion solved both of my problems. Thank you so much for you both Mike and Josh. Thanks a lot for your timely help.

Does .NET support DDE? Can we build DDE Clients and Servers in .NET? If yes, can an unmanaged application written in VC++6 or VB 6 communicate with a managed application using DDE?

This topic[^] suggests that it's not possible.
That said, you can probably use the API directly. In fact, this blog post[^] links to a project on GotDotNet.com called NDde[^] which wraps the DDEML library.

Hi,
Does anyone can help me?
I'm writing a c++ managed service in visual studio 2005 CLR template. I only created one thread with simple code in order to achieve a lightweight service as possible, but I noticed that the running service has about 7 or 8 Mbytes of memory.
What´s happening with the service that despite the user code, the skeleton of Visual Studio template allocates at least 7 Mbytes of memory! 
How do I write a service with less than 3 Mbytes like "Windows Installer", in order to spend fewer memory resources?
thanks

Since your writing in Managed C++, you have the weight of the .NET CLR in there as well. That's about as small as your going to get.
If you want a smaller memory footprint, you'll have to use unmanaged C++.

You can only set a reference to a COM-based .DLL. If it's a libary .DLL, all you have to do is P/Invoke the functions you want to use.

Thanks i have got that and now i can access the function from this dll, and can open, close and get values from the comm but only using the functions in this dll..
but now the problem is i cannot fire datareceived event on the com port which i assign
to open method of this dll,,
int hc = OpenCommPort("COM1", 9600);///method from dll which open the com1
int rtt = ReadValue(hc);///mehtod from dll
now i do the following
sp = new SerialPort("COM1",9600);
sp.DataReceived += new SerialDataReceivedEventHandler(method);
if (sp.isopen);
{
show ("Open");//but here it shows that com port is closed ,, so i cannot manage
data received event handler for this com port ,,
}
please tell me in the scenario what shud i do ?
void method()
{
// this method shud be called when the ( int rtt = ReadValue(hc);)
is called...but it does not , even i get an error when i try to open
sp using sp.open();
aftehr when i have called the dll function
int hc = OpenCommPort("COM1", 9600)
so please tell me how to create a handler for the situation ,, means the port which
i assign to the dll method opencommport there shud be a handler for that
thakns in advance
