I mean that the date should conform to ISO 8601.

I have found the solution to support all datetime formats.

No you haven't.

I said it was impossible - which it is.

There is no solution. So whatever you are doing is certainly not a solution.

What you are probably doing is testing within a LIMITED cultural scope. Which might be what you need to do but isn't what you asked. And if it isn't what you need to do then your solution will fail.

That's an oxymoron; the only real source control system (OpenVMS' CMS) isn't exactly modern.

Please don't ask for source code (again). If you want a complete solution then you will have to search for it, no-one here is going to do your work for you.

A. Changes made in JHVirtualKeyboard xaml and JHVirtualKeyboard.xaml.cs
Addition to KeyAssignmentSets directory of JHVirtualKeyboard
1.SanskritKeyAssignment.cs
2.TamilKeyAssignment.cs will be added in next
You may see changes to button names to match e.key that comes in previewkeydown-changed button names are relating to Oem.
WhichKeyboardLayout enum names changed to reflect the language name in the language itself.
Help button to type indirectly through mouse added as flowdocument which can also be used for direct typing. This has become necessary as certain letters of the language are a combination of two letters and some of the letters are quite complicated.
Lastly, paneToolbar of your xaml will have added stackpanels named SanskritSpecials and TamilSpecials. The visibility of which is changed on selection of the keyboard in cbKeyboardLayoutSelectionChanged.
B.Changes made in Demo section of virtualkeyboard.
Only one handler added to the textbox in the form of PreviewKeyDown="PreviewKeydownHandler"

I am quite new in this area of posting messages. I have wrongly placed it. I am sorry. There is no question from me. This was to be sent JHVirtualKeyboard area. Once again I am sorry to have invited your response to this.

Could not load file or assembly 'Microsoft.Practices.CompositeUI, Version=1.0.51205.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified.

Hi,

I have a view that inherits from a user control. The problem is when trying to load in the designer, I get the call stack below. I've just about given up on how to fix it and would appreciate any pointers.
(note: I can see the composite UI assembly is in the references, and the version matches (the runtime version is different though)

Thank you!

You can use dependency walker to look for missing dependencies for a dll.

As a guess the library you are using might require one or more of the following (could be others as well.)
Microsoft.Practices.ObjectBuilder2.dll
Microsoft.Practices.Unity.dll

Side-by-side installation of .Net frameworks on Citrix Metaframe servers

Hi,

A server farm used by our business currently only has the .Net framework up to version 2.0. I'd like to upgrade the entire farm to include all versions of the framework up to 4.0

As far as I'm aware, this shouldn't cause any issues with the servers or existing applications installed on the servers. I advised...

The frameworks can be installed side-by-side with no issues and an application running on .Net would need
to specifically target a particular version - an existing application running on an older version of .Net will not care that a later version of the framework is installed. Non .Net applications are not affected in any way by framework installations.

However, the company responsible for rollouts in our data silo came back with the rather vague...

We have experienced other clients having problems with a similar installation...

Has anyone experienced any issues with installing 3.5/4.0 on top of 1.1/2.0 where existing application functionality may have broken (or any other adverse effects)

I've performed installations up to version 4.0 on servers we directly support and haven't had any problems at all, I just need to convice the infrastructure guys this is low risk.

Anything I'm missing here, or was my advice correct?

Thanks

My employer has a server room, most of which only have up to .NET 2.0. Earlier this year I had installed .NET 4.0 on one of them and it works flawlessly. I have never encountered this issue either. Not at work, not at home, not anywhere else.

djj55: Nice but may have a permission problem
Pete O'Hanlon: He has my permission to run it.

My company upgraded to 4 sometime in the last year and did 3 sometime before that. No problems with running installs.

One mitigation strategy would be as follows.
1. Upgraded a single server and monitor for problems. Allow sufficient time for problems to show. Certainly a week and perhaps a month.
2. (Optional) if you have enough servers with the same type of installs then upgrade a percentage of them. For example if you have 100 servers then upgrade 10 of them. Allow sufficient time for problems to show. Certainly a week and perhaps a month.
3. Upgrade the rest of the servers in a staggered manner. Perhaps one a day. Monitor each as you proceed.

As a counter to what they said then you might ask about security patches. Presumably those are being applied. And sometimes those cause problems as well.

OK thanks both, that's what I expected but good to hear others with no issues

Create multiple instances of class for multi-threading

Hi,

I've been googling for hours without finding anything, so I have to turn here! (Frequent reader, first time poster).

I have a VB.net class (myMechModel) that is used to solve a mechanical problem. The class contains all (mechanical) parameters (mass, stiffness, length) are needed to solve the problem and it stores the results in a collection within the class. The class has a method that is being called to run the simulation (myMechModel.Calculate()).

I now want to run multiple simulations of the simulation, but change some of the parameters between each simulation. I could run it sequentially, but I really want to run it in parallel (each simulation run takes about 2 second).

I've been trying to get it working with Parallel.Tasks, but of course calling myMechModel.Calculate() just results in a threading conflict because multiple threads try to write results to the same results collection.

I've been looking into cloning the initial class for each task and then changing the values I want (like mass, stiffness, length). But before I go down that path, I'd like to here comments on what would be the best way of dealing with this!

2 seconds a run isn't really long enough to be multithreading a single Calculate. What would work is create a number of threads, say one for each processor core in the system, each with its own myMechModel instance, and let each instance do an entire range of parameters.
So, basically, N threads each with a myMechModel, and each thread repeats: { set parameters, run Calculate } for a range of parameters that you want. That way, each thread should be busy for a while and you might be able to benefit from multithreading.
Of course, you need to be interested in running enough calculations before it becomes interesting.

Thanks for the comments,

I just want to clarify somethings:

* Each run of myMechModel.Calculate() takes about 2 seconds
* I need to run parameter sweeps (mass going from 100-200 in 4 steps, stiffness going from 100-200 in 4 steps etc).
* If I run it all on a single instance of myMechModel on a single thread, I'm talking 10+ seconds.

I think the main problem I have is to figure out how many instances to create, because the number of simulations might vary quite a bit. Should I see how many threads the computer runs, create that many instances and manually setup all the runs on the different threads.

I'd much rather use something more automated/efficient such as the Task Parallel Library, is there anything I could do to use that?

Final questions, I've read about IClonable, is that the way to go to create instances of myMechModel?
