Hello,
I'm looking for a winform component that behave like the visual studio Watch.
Did anyone saw such a component ?
Thanks.

Hi,
I need to write an application that will fetch some data using WebService & insert it in to a database. This application will be put into a Windows Task Scheduler & will be run on a weekly basis. So should I go for Console Application or Windows Service application?
Kindly let me know the advantage & dis advantage of both the above apps.
Regards,
Vipul Mehta

If you plan on running it through Task Scheduler it must be a user mode application (either Console app or WinForms). A windows service is something that starts (generally) automatically when the operating sytems starts and runs even when no users are logged in. They generally don't have any UI components as well.
The issue you will have with a Task Scheduled service is that the users will be able to change the schedule and even remove it. A windows service is somewhat protected from that, but the user could still stop or disable the service.

Hi,
Not every body will have right to install or probably update the schedules for that service.
Yes I want some message to be shown when service starts OR there is some issue OR completes successfully.

I would choose a console application, since you must perform some operations and done, right? Most windows services are listening at a particular tcp port, in where requests are attended. Most of times they're ment to run forever perfoming operations under the system account. So, if you choose this way, you will have to take care of schedlule by your own -Windows Task Scheduler applies to regular executable programms or batch files onlyI would choose a console application, since you must perform some operations and done, right?

Hope this helps

Yes... my Windows Console Application/Windows Service will run once a week (through Windows Task scheduler)
Will the Windows Service keep on executing or we can run it as per the Task Scheduler?

Services never run out of the Task Scheduler. Services run from the time Windows starts until it's shutdown.
Task Scheduler runs user mode process, like Console or Windows Apps.

I have a console application, which is a WSE2 Web service with several soap methods. The application starts and the memory usage increases constantly until it reaches to approximately 700MB, then it won't respond anymore. This memory leak happens on Windows 2K3 with SP2 Framework 1.1, but i can't reproduce it in Windows 2K SP4, weird isn't it 
I've reviewed the code in each method to release resources and call Dispose if needed. I have also checked some counters with perfmon and clr_profiler, but no clue of what is causing this behavior. Please help me

This is a problem that occurs when developing with .Net Framework 2.0 (coding and debugging in VC++ 2005 Express and VC# 2005 Express):
1. Create a normal Windows SDK Console application that loads a DLL using LoadModule() and calls a function (lets call it "load") on the loaded dll.
Lets call the application "App".
2. Create the dll to be loaded: A C++ .Net class library which implements the given "load" function. "load" loads a pure .Net assembly (eg written in C#), takes a static method from it and calls it. It also needs to provide a sample ref class with a method, named ClassA and MethodA.
Lets call this library "PluginA".
3. Create a .Net Class Library in Visual C#, add PluginA to the reference list and implement the static method which will be called by PluginA. In the method it should use ClassA and call MethodA on it.
Lets call the C# lib "PluginB".
4. Ensure that all 3 projects are in different folder. Eg.:
App in App,
PluginA in App/Plugin
PluginB in App/Plugin/DotNet
What happens:
App loads PluginA
PluginA loads PluginB
PluginA and PluginB are now in the same AppDomain and PluginA's Assembly-object contains the desired type ClassA (I checked).
The Problem:
PluginB will still try to load the referenced PluginA again and fail when trying to access ClassA if PluginA is not in PluginB's working directory.
If PluginA is in PluginB's working-directory, PluginB will load PluginA again and AppDomain.CurrentDomain.GetAssemblies() will contain PluginA's Assembly Object twice.
Conclusion?
If 2 Assemblies are in the same AppDomain, they should both be able to use each other's types without having to reload them - Why is this not the case?
This seems to be a bug and MS doesn't seem to have a bugtracker...
-- edit:
It doesn't matter if PluginA uses Assembly.Load(byte[]), Assembly.LoadFrom(string) or Assembly.LoadFile(string), if PluginA is signed or not doesn't seem to play a role either.
PluginB's MethodA of ClassA (C++/CLI) contains:
array^ asms = AppDomain::CurrentDomain->GetAssemblies();
Console::WriteLine("Current assemblies:");
for (int i = 0; i < asms->Length; i++) {
Assembly^ as = asms[i];
Console::WriteLine(as->GetName());
}
When called by PluginB, the output is the following:
Current assemblies:
mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089
PluginA, Version=1.0.2837.29213, Culture=neutral, PublicKeyToken=a740aaa0a688231e

PluginA, Version=1.0.2837.29052, Culture=neutral, PublicKeyToken=a740aaa0a688231e
Where the second PluginA Assembly object has been loaded by PluginB, after I copied PluginA again to the working directory. If I do not copy PluginA, PluginB (when PluginA uses Assembly.Load(byte[]) for loading) will throw the following exception (Standard windows Console output, thus badly formatted - sorry):

If you use 'Assembly.LoadFrom(string assemblyLocation)' then that method should try and resolve all the references of the assembly it's loading. From what I've seen when playing with my own plugin stuff it'll only try and load any assemblies not already loaded. These assemblies of course have to be the same version otherwise they are treated as 2 seperate assemblies.

You can see in your output that 'PluginA, Version=1.0.2837.29213' and 'PluginA, Version=1.0.2837.29052' have different versions.

Thats just because i didn't update the copied PluginA in the working directory. It doesn't matter, even if I use an updated version, the problem is still the same, see here:
mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089

It should, but it sadly doesn't. I get the same problem if I compile PluginB with the updated version of PluginA (which I always do) and use LoadFrom instead (the output above is generated when using LoadFrom). If I don't copy "PluginA, Version=1.0.2837.29477, Culture=neutral, PublicKeyToken=a740aaa0a688231e" to the working directory, it will say:
Could not load file or assembly 'PluginA, Version=1.0.2837.29477, Culture=neutral, PublicKeyToken=a740aaa0a688231e' or one of its dependencies.
Which clearly is already loaded.

You can try hooking into the assemblyresolve event on the AppDomain:
"AppDomain.CurrentDomain.AssemblyResolve += new ResolveEventHandler(CurrentDomain_AssemblyResolve);"
that will allow you to resolve the assembly yourself if .Net fails, that will atleast let you then do the load manually from the already loaded assemblies.

This is great! Now it finally works!
Although, similar to the solution posted on the MS boards (use the GAC, which I prefer not to (although I know I am recommended to)), the reason for why the bug actually existed is unclear.

hi all,
Can some one tell me the new features of .net framework 2.0 at the architecture level,
i.e the changes in compilation,gc compared to compilation ,gc in 1.1 version.
I need the changes at the architecture level
would be happy if someone give reply.

Oh if only somebody could come up with some tool that would make it easy to type things in and search this new fangled interweb thingy. I wonder if somebody could come up with some way to do this:
http://www.google.co.uk/search?hl=en&q=new+features+.net+2&meta=[^]
See - it's easy. Just look at the top result.
Deja View - the feeling that you've seen this post before.

hi,
i checked the url already and it just shows the control suppport for .net framework 2.0 not at architecture level
i need the features at architecture level only
Thanks

I don't know which URL you looked at, but the first hit when I run the search contains the following list:[^]
64-Bit Platform Support
Access Control List Support
ADO.NET (a number of changes)
ASP.NET (a number of changes)
Authenticated Streams
COM Interop Services Enhancements
Console Class Additions
Data Protection API
Debugger Edit and Continue Support
Detecting Changes in Network Connectivity
Distributed Computing
EventLog Enhancements
Expanded Certificate Management
.
.
.
It goes on for a while, I can't be bothered to copy paste it - needless to say it shows a lot more than just "controls".
We can't guess what you consider an architecture level, but if you do not see it in the list, it is probably not changed significently. For example, why should they change the garbage collector?

I want to do write protect a drive to all system users using Vb dot net. For that i am using the below code. But I am getting Deny permission for the "special Permission" of the selected Drive. Not for the write permission.
Please see the below code.
======================================================
Dim folderLocation As String = "F:"
Dim mydir As New DirectoryInfo(folderlocation)
Dim dirsecurity As DirectorySecurity = mydir.GetAccessControl
Dim fsec As FileSecurity
Dim domain As String = LCase(Environment.UserDomainName)
Dim username As String = Environment.UserName
Dim Drive As String = "F:"
fsec = File.GetAccessControl(Drive)
For Each rule As FileSystemAccessRule In dirsecurity.GetAccessRules(True, True, GetType(NTAccount))
username = rule.IdentityReference.ToString()
MsgBox(".[" + username + "]")
fsec.SetAccessRule(New FileSystemAccessRule(username, FileSystemRights.WriteData, AccessControlType.Deny))
File.SetAccessControl(Drive, fsec)
Next
==================================================
I want to that am i doing proper method or not. if not please suggest the correct way to me for doing the write protect a single drive .
