Just a question how to change a number like 45.5 to 45.50 in TD
|
|
|
|
|
That's where it starts to get complicated, because now you need more than a "simple" text processor - which is all a regex is.
The way I'd probably do it is not to use a regex but feed the whole page into an HTML processor and start working with the data from there.
What exactly are you trying to achieve? Because there may be better way of doing it than the deconstruction you seem to be doing so far.

I want to convert all the numbers in this schéma
input
<TD>25.5</TD>
<TD>45.6</TD>
<TD>19</TD>
<TD>25</TD>
output
<TD>25.50</TD>
<TD>45.60</TD>
<TD>19.00</TD>
<TD>25.00</TD>

OK, so what's generating this table? Is it code you wrote or is this some kind of web page scraping you're doing?
|

the code is some kind of web page scraping
|
|
|
|

I would suggest you start using the HTML Agility Pack to make scraping a bit easier, but that's up to you.
It seems you're trying to treat the page as a large string an manipulate it as such. Instead of doing that, you might want to just grab the actual data, not the tags around them, store them as appropriate in your application data model, and then you can format the data any way you want when you present it back to the user in whatever application you're writing.

How to get random strings from JSON Object? For example when first time program is run on when I click on button a1 button1.Text should be "SUVO",when click on button b3 button8.Text should be "TRIJUMFALNA KAPIJA" and so on...
[ { "a1": "SUVO", "a2": "SLATKO", "a3": "BELO", "a4": "ISTINA", "a5": [ "vino" ], "b1": "LOVOR", "b2": "POSTOLJE", "b3": "TRIJUMFALNA KAPIJA", "b4": "DAN", "b5": [ "pobeda", "pobede", "pobjeda" ], "c1": "UEFA", "c2": "TAKMIČENJE", "c3": "ELIMINACIJA", "c4": "ŠAMPIONA", "c5": [ "kup" ], "d1": "ISUS", "d2": "KRV", "d3": "VITEZOVI", "d4": "OKRUGLI STO", "d5": [ "sveti gral", "svijeti gral", "svjeti gral", "gral" ], "rr": [ "pehar", "pjehar" ] } ]
When clicked button that is called "new game" buttons should have this text: And now when clicked on button a1 button1.Text now should be "hudini",when click on button b3 button8.Text should now be "zid" and so on...
{ "a1": "hudini", "a2": "trik", "a3": "plašt", "a4": "predstava", "a5": [ "mađioničar", "madjionicar", "čarobnjak", "carobnjak", "madjioničar" ], "b1": "svila", "b2": "bicikl", "b3": "zid", "b4": "država", "b5": [ "kina" ], "c1": "kornet", "c2": "frikom", "c3": "delta", "c4": "kugla", "c5": [ "sladoled" ], "d1": "školjka", "d2": "aparat", "d3": "sluh", "d4": "bubanj", "d5": [ "uši", "uvo", "usi", "uho" ], "rr": [ "štapić", "stapic", "štap", "stap" ] },

You use the Random class to generate a random number and pull that index from whatever string collection you have.

Every time I see this I wonder about it and every time I ask, I don't get an answer. Maybe you can tell me what benefit is it that you think you get from converting a string to a string?

I'm trying to handle the case where the client calls through the hub into the server and an error occurs.
If an error occurs then there could be an inner exception. So far I have this but it feels funny. Anyone have a better way?
_hubProxy.Invoke("SomeMethodName", model).ContinueWith((t) =>
{
if (t.Exception != null && t.Exception.InnerException != null)
{
throw t.Exception.InnerException;
}
});
If it's not broken, fix it until it is.

The inner exception may have an inner exception, and so on. Instead of throwing the inner exception, I'd throw the outer one, as it would (should) contain all inner-exceptions.

Since Task.Exception is an AggregateException you've gotta worry about multiple inner exceptions in addition to the current exception the AggregateException represents unless you know precisely how many exceptions can be thrown. My ideas:
Log current exception, flatten (in the case of nested AggregateExceptions), and re-throw:
_hubProxy.Invoke("SomeMethodName", model).ContinueWith((t) =>
{
if (t.Exception != null && t.Exception.InnerException != null)
{
throw t.Exception.Flatten();
}
});
Handle exceptions you know how to handle, re-throw the rest:
_hubProxy.Invoke("SomeMethodName", model).ContinueWith((t) =>
{
if (t.Exception != null && t.Exception.InnerException != null)
{
AggregateException ae = t.Exception.Flatten();
ae.Handle(x =>
{
if (x is IndexOutOfRangeException)
{
return true;
}
return false;
});
}
});
You can avoid Flatten() if you're absolutely sure there are no tasks inside your task. Also the reason I used Handle() is because it conveniently re-wraps all exceptions that did not return true (not handled) in an AggregateException and re-throws them. If you can handle everything or are sure of exactly what exceptions can be thrown you could iterate over the AggregateException.InnerExceptions collection instead and re-throw as you desire.
EDIT: Quick addendum: If you're using C#6 you can simply the if-statement to:
if (t.Exception?.InnerException != null)
Looks cleaner to me but to each their own

I posted this tip that tries to see if an exception in the chain is of a particular type. You could use the code as a basis for bending it to your will.
Find your inner exception

I am trying to keep thread/process active, when application is minimized to tray. As i want some tasks to be performed in background in app state = minimize.
As I have defined a async delegate to capture a callback for an event, when the app is minimized the process is completed and the app is supposed to listen for event fire, but when the app is minimized the app does not reports to the event, and the callback to the delegate doesn't occurs but the following event fire and all the respective tasks are performed when app is maximized.
Please guide and help me.
