In 1971 (yes, 40+ years back), a book came out on Flowcharting.
The book contained the usual blurbs on the dust jacket, including one about how the book even covered sharpening the pencil.
But the most telling one was: Flowcharting is for the mentally retarded.
Honest.

I remember that there was an ActiveX control for setting the skin of a form on VB. Can anybody remind me with its name?

Thank you anyway. I've just found it. It's Actskin4.ocx
That's the file I was looking for, but can it work also on C#? I wonder.

Probably, bit why would you want it to? Use WPF and you can retheme the app all you like.

Now that's another problem that I'm gonna post in this website, because I can't make any WPF projects

I have an Ethernet connected motion controller that I need to get information from. I'm using WPF (C# flavor) for the project. The goal is to get data from the device as fast as possible so the UI doesn't seem sluggish.
My thought was to spin off a background task that constantly polled the device for information as fast as it could run. It would fire events when certain groups of data were updated. Another class would monitor for these events and then set dependency properties that would update the UI.
I have a couple questions:
1) What is the best way of starting the background task? I want it to close when the main thread is closed and not stop the main thread from being closed.
2) Any helpful advice as to how data can be retrieved on one thread that will eventually be displayed on a different thread.
I have only toyed with multi-threaded applications up to this point. I'd rather ask and do it right than to find out later there was a better way.
[UPDATES]
This is on a closed network on the machine. It is not going over a corporate network.
The device does not fire events. It has an API that allows data to be requested and then it replies. Right now I am using a DispatchTimer to request updates at a regular interval. It is running at 25ms without any issues. I was looking at trying to free my UI from my polling routine in case the device locks up or stops responding.

If you think you can, you will.
If you think you can't, you won't.
Either way, you're right.

This is a very bad idea resulting in a very high system and network load. You should check if the motion controller provides some kind of notification messages (sending data to an established network connection).
Using a worker thread for such network communications is the common and best way. To stop such a worker thread, it is usally listening for a terminate event (besides the communication events) that can be signaled when your application terminates.
To pass data from the worker thread to the main (GUI) thread and vice-versa you must implement some kind of inter-thread communication.
How to implement threads and inter-thread communication depends on the used language.

I've updated my post with some more information.
Basically, this is on a closed network. There aren't any other devices connected. Also, this will be in C#.
Thanks for the advice.

If you think you can, you will.
If you think you can't, you won't.
Either way, you're right.

The System.Threading.Timer can help you: its callback function does not run in the thread the timer was created.

Hi Guys,
Currently when client is logged in to my system, the user's session is bound to some server (lets say there are 4 instances of the same server on 4 PCs) and is handled only on this server.
I'm going to put servers into cluster with distributed cache where user sessions will be stored and be accessible from each of these servers.
There is a problem, I dont know which distributed cache product to use (i need exactly .NET solution), I found something about memchached, microsoft's AppFabric, etc..
But everything is very superficial (or i'm bad googleman  ), could someone advice something? what is the best in the performance? maybe there is some good comparative analysis topic, etc?
10x in advance,
Pavel

Hello everyone,
I just wanted to ask, how can you have a different icon from the windows task-bar one and the one that appears on the form, for example (see graphic/link below):
Click for picture.
I couldn't found out which topic to post it in, because I do not know which programming language(s), do this. Thats why I posted it here because it is design and architecture for programs. So what programming languages do this, answers will be fully appreciated.
Regards,
Brandon T. H.

You can set your application icon under properties - application tab - resources - icon in visual studio, and this determines the icon for your application on the desktop and the task bar. You can further set a different icon for each separate window in your application, which determines the icon displayed in that window's title bar.

The only way I know of is to use two windows. An invisible main window (the icon of which is shown in the taskbar) and your second window becomes the main window for the user.

Dear Team,
I have a Visual Basic 6.0 Application with 10 timers in one form.Time Intrval Set For timers are different.
Timer1-1000,Timer2-10000,Timer3-10000,Timer4-10000,Timer5-10000,Timer6-10000,Timer7-10000,Timer8-10000,Timer9-10000,Timer10-10000.
The problem is sometime all timers does not fires on its interval...but most of the time works correctly.Because of this skip reason I am looking to work in wpf as I have read it has dispatcher.
I want good suggestion from all what is the best solution of it...Suggestion is always appreciated.
Thanks

I suggest you use another forum. This has nothing to do with design or architecture.
Failure is not an option; it's the default selection.

It's unlikely that will make any difference unless you are certain that you have diagnosed and resolved the original problem.

As long as you do not endeavor to find what the actual problem is, switching over to a different technology will not help you.

Put some code on the first line of the event to log the time that it's fired. You'll find that it fires around the time it's supposed to, unless the app is in a loop without yielding processortime for the messagepump.

Fresh from the success of my Inheritance question last week, I have another relating to the data behind those objects. Remember I have been using a 1:1 relationship between objects and database tables. I had Routes, Stages and a Many : Many relationship between them coverd by a RouteStage table
But the new design will be along the lines
Class CStage
{
Stage details
}
Class CRoute
{
Route Details
List <CStage> List of Stages
}
How do I represent this on a relational database.
My research is leading me to a term called "Object Impedance". I have ideas for some none-too-pretty methods on the revised CRoute, but I am open to clever suggestions to best represent this scenario.
