VNC will show you the remote desktop, NOT a single application. Sooooo you would just need to launch the MMC on the remote desktop and you'll see it. All it takes is a couple of mouse clicks on the remote machine.
...or am I missing something?
For what you're talking about, we just use Terminals[^] and launch the MMC we want in the Start/Run box.
MMC is just a kind of Plattform. The Connection you want to do is not in the MMC, it is part of the Plugin what you load to your MMC.
You can add for example the Plugin in for DHCP Management and while you add them, you can deceide, what server you want to connect with. Afterwards you can save this settings as "DHCPonMyServer.msc" file.
If you want to run this Plugin on this server again, just run the MMC with this file as parameter.
You can also add more than one Plugin to an MMC so you can create an individual MMC File for each of your server.
Yes I am sure that you can do that if you just give it a try. In the future, please try and create a meaningful title for your posting as "c#" is not very descriptive of your question, if indeed you meant to ask some sort of a question.
i want to store the webservice method's XML output[the one which we get after invoking the webservice method]. Below is the code which am using and the output that am getting after executing it. Please help to get sort of this....
After adding web reference that consists of webservice URL am using the below code.
my application is written in VB.NET using Visual Studio 2008 and it runs an a Windows CE device, so it uses Compact Framework.
I need to avoid multiple instances of the application and I don't know how to do it.
I have found some solutions but only for the full framework, not for the compact.
Other solutions to this problem talk about mutex: when the application start I should create a mutex if this is the first instance of the application or stop the application if the mutex already exists (or something like this)... but I don't know how to do this.
Sorry for the cross post but this doesn't fit neatly into Silverlight/WPF!
I am asking this in the WPF forum because this is a WPF app but this question does not necessarily pertain to WPF, i.e. the UI thread.
Here is the scenario:
I have three (3) threads. Thread One (1) call it the Master Thread; Thread Two (2) is a Ethernet Comm thread; and Thread Three (3) is a GPIB comm thread. Both communication threads handle asynchronous communications from remote entities. At this time there is only one entity hanging off each comm type.
I have implemented a mix of EventWaitHandles and delegates. This all works pretty well. Just think this architecture is a bit ...... ugly. So which one is better/safer?
My concern is as follows. With delegates, for example, the Master thread registers an event handler with Thread 2 and an event handler with Thread 3 for messages that come in. Obviously data could come in near simultaneously. So Thread 2 encases a message in an EventArg and invokes the event on the Master thread. The Master Thread begins processing and then Thread 3 encases its message in an EventArg and invokes the event on the Master Thread. What happens? Does the Master Thread stop in the middle of handling the first event to service the second one? Does the second event wait until the first event is processed? What if Thread 2 gets another message and invokes the event again while the Master is processing the first event?
I wonder if using a queue and an manual Reset EventWaitHandle is not a better idea as the Thread 2 can check the status and wait until it is reset before putting the message in the queue and setting the EventWaitHandle again.
I have a similar case: multiple threads accessing temperature controllers over a serial port; a temperature charting thread; another handling user interaction.
When I need to access a shared resource (like the serial port), I’ve been using a C# “lock” at the appropriate point to block a competing thread.
It’s been working well and does not require the threads to do anything “special” (other than insure all requests are short in duration so as not to tie up any one thread for an extended amount of time).
Good solution! I am using that in a couple of places and that helps. More I am trying to avoid a mix of EventWaitHandles and delegate/event handlers. I think this is a bit "messy" looking. But with schedule tight sometimes you just have to do what you have to do
OK, I cannot get my head around the whether there is a difference between the 'classic' (perhaps long winded) way of doing it, multiple classes and the 'new' Yield route to (apparently) the same end.
I can understand the classic route (I think), see the code below.
Yield confuses the heck out of me, if I understand it correctly then it's absolutely genius, I get the idea of a state machine (I think) and logically it sort of makes sense but I am not at all confident.
Can it possibly be this simple? You just make that one method as simple or complex as necessary for your situation? (Warning, silly example since arrays can already be enumerated, but it's easy to demo)
Private _Thing AsDouble()
Public Iterator Function GetEnumerator() As IEnumerator Implements IEnumerable.GetEnumerator
If IsNothing(Me._Thing) ThenThrowNew InvalidOperationException()
EndIfFor Index AsInteger = 0ToMe._Thing.GetUpperBound(0)
What I understand to be the 'old way'.
Private _Thing AsDouble()
PublicFunction GetEnumerator() As IEnumerator(OfDouble) Implements IEnumerable(OfDouble).GetEnumerator
EndFunctionPublicFunction GetEnumerator1() As IEnumerator Implements IEnumerable.GetEnumerator
Private _Thing AsDouble()
Private _Index AsIntegerPrivate _curItem AsDoublePublicSubNew(ByVal Thing AsDouble())
Me._Thing = Thing
Me._Index = -1
Me._curItem = NothingEndSubPublicReadOnlyProperty Current AsDoubleImplements IEnumerator(OfDouble).Current

I realise this is a late answer, so maybe you've already figured this out. But maybe it's still worth something, so here goes:
I think the short answer is that Yield is absolutely genius. The 'classic' way as you put it actually is the same implementation over and over again, where only the return value varies. What yield does for you is that it allows you to construct an IEnumerable directly from a function (using Yield statements), such that every time MoveNext() is called, the function takes off where it left off until the next Yield statement.
So, yes, you can just use yield whenever you want I think the only possible issue with it is that it's probably slower than a proper custom ('classic') implementation, so if you have A LOT of elements AND you notice a performance bottleneck in enumeration THEN you might consider getting your hands dirty.
I'm just writing some instructions for installing a .NET COM component.
The first steps are to use regasm and gacutil, but these don't seem to be distributed with the actual framework, and you need to use a version that matches your .NET v or above (i.e. can't use a v2 regasm with a v4 dll).
So I want to say where you can get a copy from, but what 'package' contains these to components? is it the .NET or Windows SDKs?
I'm developing a web tool and I started using asp.net with c# ,, an important part of the code is already written in c++ , I was looking and searching around and I kind of understood that I can use c++ as the web development language. Is this true ?
this is my first time developing a web tool, sorry
It's a royal pain in the ass, but it can be done. You have to use Managed C++ (C++/CLI), but it can be done. There are no ASP.NET templates so you have to write every tiny bit of code and wire up everything yourself.
It's really not worth the pain. You're not getting that much of a performance bost to make it worth the trouble. If there are critical pieces of code that must be hand optimized, then you can write your critical code into components and use those in the C# or VB.NET code for the site.
I played around with it some time back and it looked pretty promising.
Twenty years from now you will be more disappointed by the things that you didn't do than by the ones you did do. So throw off the bowlines. Sail away from the safe harbor. Catch the trade winds in your sails. Explore, Dream. Discover.
I did configure the Symbol LS3408 scanner to be a USB scanner, not a keyboard.
This was not my question. The question was, if anyone has made some C# code, that gets the reading from an USB barcode scanner. I know there are solutions out there, where you get the reading as a keyboard input. I don't want that.
Your best bet would be to download the Scanner SDK from here[^]. Using someone else's code is going to be problematic at best as their code is going to make assumptions about the scanner that do no apply to your situation.
i have a listview control in my winRT application and, when the user taps a tile, i´d like to save the previously selectedIndex.
i can´t find an appropriate eventhandler to achieve this;
i only found SelectionChanged-event, but, as one might guess, at this particular time the Event is already fired and i retrieve only the new selected index...
can anyone please Point me to the right direction... eh, to the right Event ?
and - if someone knows where to get an elaborated overview for the LifeCycle - as known form ASP.NET pages - that would be highly appreciated...
