Hi there
Wondering generally how the server side of an application server is done (non web based).
Say you wanted to write an accounting program. The server would run on Windows Server 2008 for example and handle business logic and database access. The client program would have the client forms, etc and obtain data from the server.
Is the server software usually set up as a Windows service normally? It would listen on certain ports?
How does the server handle multiple concurrent users? I would imagine that after authentication, some sort of thread is created to listen for requests from the user?

I'd try to check if a database-server would suffice

Yup, that way it starts when the machine starts, without the Admin even having to log in.

Any free port will do.

Preferably by spawning a thread for each new connection. There's an example on MSDN on using sockets, with the server example here[^] and the client example here[^].

Then you choose the version of the framework you are targeting.

Hi,
your app can detect some version numbers; one of them through Environment.Version

I think you are setting the location in the Form Load event. Try to set the location in the property window during design time. If you must do it at runtime, set the Visible property of the form to false and try this in Form Load event:
this.Location = new Point(x,y);
this.Visible = true;
Hope this helps,

I have installed visual studio 2003 on my computer.When trying to run an application it gives me error message that unable to start debugging on web server this project is not configured to be debugged.I have installed IIS on my computer but it still gives me this error.What could be the reason behind this is it the IIS.What are the steps that i can take to resolve this error.Also one more thing that when initially i tried loading project in it i was asked for a conversion to the required format using visual studio conversion wizard.Originally the project was developed in visual studio 2003.

Dear, Try this
Go to IIS -> Right Click on you project directory -> In Directory Tab->Click on Application Setting's Create Button-> Click Ok
It may resolve your problem...
Otherwise Google this error.

I have an assembly, which when is strongly types, returns incorrect results(A large Flaoting No) . But when the same assembly, has delay signing on the functionality works OK.
This assembly make use of the Legecy DLLs create in C++.
As I understand, there Strong Naming is linked with integrity of the assembly and doesnot effect the functionality.
Can some one please advise me if what could be the possible issue here.
Regards
Vineet

If your assembly is signed, it will only work with the versions of the referenced DLLs referenced when it was signed. If you recompile a legacy dll and the versioning changes, you will have to either re-sign the assembly or edit the configuration file for the assembly (or the exe using the assembly) to allow the new versions.
Note: you should not be signing an executable, only shared dlls should be strong named.
See this for detailed help[^]

I started using .NET C# with framework 1.0 , upgraded my applications through VS 2000 , 2003 , 2005 and now 2008 . each upgrade will install the new framework on my computer . Now I have all these .NET framework related applications which is taking large space
Microsoft .NET compact framework 1.0 SP3 Developer
Microsoft .NET compact framework 2.0 SP2
Microsoft .NET compact framework 3.5
Microsoft .NET Framework 1.1
Microsoft .NET Framework 1.1 Hotfix (KB928366)
Microsoft .NET Framework 2.0 Service Pack 2
Microsoft .NET Framework 3.0 Service Pack 2
Microsoft .NET Framework 3.5 Service Pack 2
, currently I am using VS2008 , can I remove application related to frameworks prior to 3.5 .
thanks

You should have done so as you upgraded.

You can uninstall all of the .NET 1.x versions. Everything at 2.0 and above is dependant on the 2.0 CLR, so you cannot remove them. You must leave 2.0 and 3.0 in place in order to use 3.5. I think the .NET Framework will get a new CLR with the release of 4.0. Someone else is going to have to confirm or deny that though. I don't have the resources available to test it at the moment.

You should not remove ANY of them, as you may have applications that depend on them. Given the large disks on modern systems, the amount of space used by the framework binaries is pretty trivial. Vs2008 requires .Net 2.0 and all subsequent frameworks, so at most you could only remove the 1.0 and 1.1 frameworks. If you remove these, and it breaks an application that needs them, you will end up installing everything from scratch. Best advice is to leave well enough alone. Find something else to clean up if you are low on disk space, or think about moving to a larger drive.

Good, here is your first assignment, read this. Hint, look at item 3
http://www.codeproject.com/Messages/3122367/How-to-get-an-answer-to-your-question.aspx[^]
If the code is written in .NET you can use a tool like Reflector to look inside otherwise you'll need a decompiler. However, be warned that if this is commercial software the EULA most likely prohibits decompiling.

Hi
I have associated a WPF application with a file(say abc.vdp)
When abc.vdp is clicked on ,application will be launched .
Before loading ,all data from folder where abc.vdp is residing will be copied into a temp folder.
When application is closed actual folder and files will be deleted and temp folder contents will be copied.But while deleting exception "folder cannot be deleted ,it is being used by another process" is thrown.This happens only if launched by .vdp files.
When executed through code folder gets deleted without exceptions.
Any idea on why is this happening ?
Please suggest a solution.

|

The only explanation is that you still have a file open in that folder.

Greeting,
I want to know to code an application to be multi-threaded one and each thread run on different processor using Visual Studio 2005?
Any help will be thankful if it fits into the content of this message...
Thank you..

You start by understanding threading and designing your app properly. Noone can tell you what to do because we know nothing of your application, data and synchronization rquirements, or anything else useful about your app. There are many different methods that can be used and various options that go with each, so it's pretty much impossible to tell you based on the information you supplied.
I suggest you start by Googling for "vb.net threading" and start reading everything you can.

Mr. Dave..
Thank you for being interest of such a topic..
I want to know only if it is easy to do so or not...
My application is a utility that run on windows server 2003 on computer of 4 processors..
when running this utility it will execute only on one processor and the others are not involved..
So, is multi-threading the answer to make all processors involved in executing this application. If it can be the solution, then what you think of how I could start implementing...
Thank You..

Whether Multithreading is the proper solution, again, depends on WHAT THE UTILITY IS DOING. Is it easy to do? That depends on what you want to have each thread do.

What is stopping you from trying it out? Operating system manages the threads and it's scheduling. On a multi-processor system, it may utilize multiple processors to execute the code in parallel or it may use time-slicing and use only one processor. You don't have any control over this.
DND wrote: If it can be the solution, then what you think of how I could start implementing...
As I said, write code and see how it behaves. Proper threading can improve application performance drastically. Threading is not very trivial. So I suggest to refer a good book before you start writing code. Here[^] is the best one you can get online.
