I have several assemblies that have been registered for COM Interop but have not been installed into the GAC. There are all installed side-by-side in my application directory. One of the assemblies is a Windows Service exe. Things have been working fine but occasionally the service fails to start. I was wondering if this was due to the long startup time caused by the JIT compliation. I have now tried using Ngen to pre-compile all the assemblies. I see that they now appear in the GAC and have a cache type of ZAP? My question is - can I tell programmically if I'm using the native images I've just created? If not, can I verify that application is using the native images? How does the runtime find the native images? Especially the service which is configured to point at the original exe?

May be.

You have pre-jitted one or more assemblies so the resulting images are stored in the GAC for future reference. Without pre-jit, assemblies are jitted on-the-fly in memory.

This question sounds weird. You are always using native images, whether they are from the GAC, or from in-memory jitted images.
What's more interesting to the issue is what is the relationship between an assembly in a private folder referrenced by a main assembly, with the same assembly stored in the GAC : in other words, which assembly is used ? The answer is it has a lot to do with versioning rules and strong names.
My recommendation is to read Jeffrey Richter's "Applied .NET framework programming" book. It's all there.

Hi,
I was wondering if it is possible to program a low level network application in .net. I mean I want to choose the network interface that handles the packets sent from my app, I want to get every IP packet that passes thru my computer, and so on...
Can anyone give me any pointers?
Thanks a lot,

I'm pretty sure there was an article posted on CodeProject doing something similar to what you want. Bascially the code resembled a packet sniffer applied on a particular interface. The article is here http://www.codeproject.com/csharp/networkmonitor.asp?target=network%7Cpacket[^]
There are actually a few articles here on CodeProject. Do an article search on network packet.
Hope this helps.

Hi all,
I create a worker thread to do some stuff, when that thread completes I would like to make a call from that thread to main thread to tell it to take a new course of action.
In a windows forms environment you can call:
this.Invoke
but what if your developing an assembly or console app , is there an equivalent. I've tried using delegates etc but when you look at the
Threading.Thread.CurrentThread.Name property your still 'in' the worker thread.
Anyone know about this.
TIA.

Are you trying to make sure that after something happens in your worker thread that a method is executed within the context of the main thread, or are you just trying to signal the main thread from your worker thread.
Probably the easiest way would be to pass a waithandle to your worker thread and get your main thread to wait on the handle (or check it regularly) for the handle to be signaled and then go from there. But if thats the case then you might as well recode the worker thread as an asynchronous method call.
The above may not be to your liking Looking at the Mono project, the way they have implemented System.Windows.Forms.Control.Invoke() is place the delegate passed ot Invoke() in a queue. This queue is then checked in the windows message loop (which executes in the same thread as the control was created in), and any delegates in the queue are then called.
So you could create a synchronized queue, get your worker thread to place a delegate in this queue, and then either get your main thread to periodically check this queue or signal a waithandle, and then get the main thread to execute the delegates in the queue.

Hi Andy,
I was looking to actually call a method on the main thread in the same way as Control.Invoke() 'marshals' the call to the main thread in a windows form.
Your suggestions of passing a waithandle to the worker thread or using an asynchronous method call sound good and I will certainly look into them ( especially the async call, that hadn't occured to me at all )
Your description of how Mono works is very interesting and I imagine that microsoft do it in a similar way or at least thats how it appears to work. But it does seem to be a bit tricky for my feable brain and right now I need a quick and dirty solution.
Thank you very much for help, it was very useful to me.

I am having the same problem.
I am calling the FileWatcher component in the .NET framework from a server (middleware) class. If I place this on a form, I'm set, I just hand the FileWatcher class a reference to my form. The file watcher class then calls the form's Invoke method.
However I don't have a form, so am forced to implement the ISynchronizeInvoke interface myself.
Your suggestion to go look at the mono project seems like a good start. Can you tell me where to find this project?
My solution so far is to implement ISnychronizeInvoke and to create an delegate instance that will be executed when the callback is executed.
1. I register a call back.
2. The call back is executed. The sender is the operating system.
3. I then execute a delegate that I instantiated on the "target" thread.

Visual Studio .NET only creates Windows apps, but there is a cross-platform, open-source version of .NET called Mono. You can use SharpDevelop[^] which can create Mono apps. SharpDevelop currently does not have many of the features of VS .NET, but it is being steadily improved, and it is FREE. You cannot currently run SharpDevelop on any OS but Windows, but I believe next version (0.95) will allow you to do this. You cannot build windows forms apps that are cross-platform yet, because System.Windows.Forms cannot be ported to other platforms.

As long as theres a clr on that operating system it will work. Take that with a pinch of salt though cos who knows what features etc will be supported on that version of the clr.
Mircosoft have made one called rotor that runs on
'Windows XP, the FreeBSD operating system, and Mac OS X 10.2'
here[^]
Also someones doing it for linux, mono.
mono[^]
Which looks cool.
I have no experience with either of these implementations but I'll bet your in for some headaches trying to get your code to run on them as they seem to still be in development.
Hope this helps.

I am creating a "Visual Studio .NET" deployment project to install some component assemblies.
I would like that the setup program make the assemblies appear in the Visual Studio .NET "Customize Toolbox" dialog box.

In your deployment project for you "developer" version, create a new registry key under HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework\AssemblyFolders. Use a unique string for the key name. The Default value should point to the directory where your assembly is located.
You'll need two copies of your assembly, one in the GAC, and one in a normal directory.
Hope that helps.

I've been using Visual Studio 7.0 to develop a C# application for a while. Today, I downloaded and installed the .NET 1.1 framework and SDK. But I can't figure out how to get Visual Studio to start using the new version of the SDK. If I rebuild my project and run, it's still using .NET 1.0... you can see this in the output:
'DefaultDomain': Loaded 'c:\winnt\microsoft.net\framework\v1.0.3705\mscorlib.dll', ...
...
How do I get Visual Studio to start using the new version?
Part of my problem may be that I didn't install Visual Studio in its default location. I put Visual Studio in one place, but I installed the new SDK in the default place (i.e., Program Files).
I hope that I don't have to buy another copy of Visual Studio just to use the new SDK

I know you may not want to but you can upgrade to VS 2003 just for a "cost-of-materials" price, i.e., about $30.
However, there should be a way to do what you want but I've no idea how!

Actually, Visual Studio 2002 only targets NET 1.0.You you can not use the .NET 1.1 from within Visual Studio 2002. (
To build a .NET 1.1 App you have two options:
1. Use Visual Studio to write and organize your files and then use the command line compiler on the 1.1 SDK folder to build your app (but remember that NET 1.1 introduces some code-breaking changes to NET 1.0)
2. Upgrade to Visual Studio 2003

I have question. We are planning to write major stand alone app in .NET which hosts various GUI (Windows)
Screens( in ActiveX Objects) . Does .NET Remoting help us to host GUI Objects display remotely ?
Does .NET Support to display GUI Obejcts? or its just messaging protocol?
If you have good links please point me there
Thanks

I am creating a setup project and I would like to install some assembly files into the Global Assembly Cache (GAC). How to indicate that in the setup project?
|
|
|
|
|
It depends on the setup program. But if it supports custom actions, then you can do
"gacutilpath\gacutil.exe" /i "assemblypath\assemblyname.dll"
where gacutil path is the path to gacutil.exe and assemblypath is the path to the assembly.

I have finally discovered that the Deployment project in Visual Studio .NET offers a GAC folder. I have just, when creating my deployment project, to place my assemblies in this folder.
And now, I have another question: I would like that the setup program make the assemblies appear in the Visual Studio .NET "Customize Toolbox" dialog box. How to do that?

Hi. Can you please tell me what the AutoEventWireUp is for? I've read the explanations in SDK but I couldn't understand what it does.

I know you can make web-references dynamic, which then only need a small change in the web.config file to repoint them to the new location you want to look at.
My question is, can you do something aking to this with regular (non-web) references? Perhaps using the web/<application>.config file, or a manifest file or something?
We are looking to create a central library directory where we can keep our common libraries for access from any machine which needs them. One consideration was 2K's Distributed File System, but that is an awful lot of complications, especially since it means getting our domain administrators involved. So i was thinking there might be an easier way by being able to just put in a line which tells the app where to look for the reference at run-time. yes??
Thanks in advance.

There is a way of doing this with regular refrences though you are required to use reflection to dynamically load the assembly you are looking for.
Have a squizz here http://msdn.microsoft.com/library/en-us/cpguide/html/cpconhowruntimelocatesassemblies.asp[^]
It would probably be eaiser to just setup a network share for the library, and add a project reference. I think deciding which asseblies to use at runtime is most suited to situations where you know the interface but you want the freedom to decide which assembly you will use to implement that interface.
