What does the variable startHour (and the property StartHour) mean in a list of cities ??
and why is a foreach loop used to set it (to whatever happens to be the last city.OpenTime) ?? in a method called Show... where nothing gets shown Confused | :confused:

that's not my problem. I just want to read the value from a Xml file and to convert it to time, in a string without date.

You can't have a time without a date. You keep using TimeSpan. That shows the difference between two times / dates - unless I am mistaken. Anybody?

You have two options - convert all times to 'today' + your time. You can then sort them.

or

Or convert your timestrnig to an integer, throw all the ints into a collection and sort them.

string myString = "07:30"

int myTime = int.Parse( myString.Substring(0,2) ) * 60;
myTime += int.Parse( myString.Substring(3,2) ) ;

This will give you the time in minutes, as aninterger. (from memory, so could be typo's etc);

Guys,

Last week I asked here on CP for some aid in converting something like "aabb" to "aAbB". You had to read a textfile, convert it and show it in a textbox.

We participated with about 10 or 15 people and the result was that my application wasn't the fastest (and definitely not the slowest), but I did got a compliment for having the shortest code. Most participants used a lot of delegates and events with different threads etc.

Thanks to all those that helped me Smile | :)

I don't remember your post last week, but from the description you gave just now, I don't see where delegates and events could come into a solution like that.

lol, he could convert a file of 8MB in 2,9 seconds. (including reading in and putting into the textbox), he used several different classes and he added different conversion methods for ASCII, UTF etc...)

My conversion, including reading in and putting into textbox was not even 20 lines Smile | :)

1) Know what do you want
2) Be sure that what you want is meaningful and understandable
3) What does "convert it and show it in a textbox" means? Convert to what? Any rule, regular expression, upper-lower case, flower, tree, insect...what?

If you want to convert every occurance of a string to a reqular expression then use a predefined regular expression and trace the file with a buffer of whatever size your computer can handle. If the file size in not very big, you can read it completely into the memory at once and then process.

Hope this helps...

Looks to me like each line only has a space between the key and the value, so use the Split method on the string class to turn them into an array of key and value, line by line.

store everything in a string

for eg: string str=data;

string[] temp = new string[1000];
temp = str.Split('\n'); //now wat this will do is,each line is stored in each array

for eg: temp[0] will have "GENEVAVERSION 5.0"
temp[1] will have "BILLSTYLE 2" and so on

and wat u have to do is that, take a for loop and parse til the end of the temp array and use one more split function and finally store that in XML

did this help.......

Socket exception.

I have a client-server application. When I try to connect to the server application using the loopback address, it runs fine, but if I give the actual IP or if I try to connect a server that run on another machine, it throws,

System.Net.Sockets.SocketException: No connection could be made because the target machine actively refused it

excpetion. Has it got something to do with .net security settings that we have in Adminstrative tools in the control panel? I've just set the local intranet security to "full trust". Any help?

do u have any kind of firewall installed in your system or in the other system. If there is, then disable it and try.

If this doesnt help , then come back with the code

Re: Socket exception.

Eytukan2-May-07 3:44

I guess it's not something related to the firewall, Because I just tested it with my C++ C/S application with the same port. It works fine. Btw, I just reached home. Dont have the code with me now. But it's quite simple.
It's quite primitive one, A simple TCP listener waiting to accept a TCP client. with 127.0.0.1, everything works cool.

That is true for 127.0.0.1, what port number do you use, in .NET you must use a port number that is greater than 5001(As I remember).

I gues it's not for .net in particular, but in general it's safe not to clash with the reserved zones.I'm in the safest of zone. Above 20000!. I'm using 20555. And no other application uses this port in my pc.
