I've programmed Myself Into A Corner - C# Discussion Boards

Dear Sir,

Thanks for reply.

I am trying to add Winsock Dll with Application. But it is not adding.

So please explain me how to use it.

Thanks

If you can think then I Can.

Using a generic definition of "monitoring", any off-the-shelf proxy server will do this already. No code required...

Dear Sir,

I want to add it with my code so i think code is required.

Can u please describe something regarding Port Monitoring. and Is it fixed IE or Mozila or opera alwase access 8081 port.

If you can think then I Can.

OK, then you're going ot have to write a proxy server that the browsers will have to use to get to outside web sites. I hope you're up on your TCP/IP programming skills.

I have no idea what you're trying to say here. Port 80 is the normal HTTP port a browser makes requests on (non-secured). 8081 is not assigned to anything.

Hello everybody,

wininet.dll Provides api(FindFirstUrlCacheGroup etc..) for getting information.But it is only working with Internet explorer. Now Same as I want the information for Mozialla ,Opera, Google Croma.

Help required.

Thanks

If you can think then I Can.

Yeah. I already told you what your only option is if you want to support all browsers. You must write a proxy server, or get one off-the-shelf that does what you want.

Hello Everybody,

The best example if u want is given below.

A good while back I started a program to read csv files, classify the lines to separate the chaff from the wheat, then convert the text fields to proper types and save the records to a remote SQL Server database. As usual, I did it half in the bag, late at night after very long days at work, that being the only time I have available. I had to drop it for a couple of months, but I'm now back into it and trying to figure out what I was doing. Predictably, it's a mess - spaghetti code, for lack of a better term. It works, that part that I managed to finish back then, but the major hurdle lies ahead and I'm refactoring the monster before I begin again. But I digress...

I had no trouble using the StreamReader to read the data, and at your collective suggestion, implemented ugly, nasty little Regexes to classify the text lines into keepers and crap. I asked about creating a new database on the remote SQL Server instance, and after being told that it can't be done, did it anyway. All that works great, jumbled mishmash though it is. What's stumping me is this:

On first run, I want to create the database and save all the neccesary connection information in the AppConfig file so I won't have to enter it manually. I can't figure out how to do that, despite searching MSDN for articles on the subject. I believe that there exists a whole class devoted to manipulating the AppConfig file, but I'm stumped and have little time available to search through all the irrelevant links MSDN returns. Can someone give me a quick clue? I know this is trivial stuff, as every program that accesses a database uses it, but I'm not having much luck with it for some reason.

Thanks a bunch in advance. If I didn't have this crowd to assist with the sticky bits, I'd probably quit programming at all, even as a hobby - it so easily becomes incredibly frustrating. I'm unspeakably grateful... Blush | :O

Is the ConnectionStringSettings class[^] what you are looking for?

Excellent! Thanks a bunch! Big Grin | :-D

The thing you're looking for is the ConfigurationManager :

Thanks!

The previous answer adressed the specific problem, and yours the more general one. I appreciate it!

Hi there !

I start to developing a hotel managment system C# + MySQL database.
I have to make some like graph schedule (it's only for view)

It should looks like:

for example on some month...
is 3 persons in room2 from 2 to sixth day of month and the color of this line...

      1 2 3 4 5 6 7.... 31 (days for months)
room1   
room2   3 3 3 3 3
room3

it will download the data_from and data_to of reservation some of specified room, the type of residence which is declarated in specified color and then at last how many persons are in this room
and now it will draw lines of a given color from the day-to-date and in the middle of this line in each row of the color line the number of people in this room

I wonder how to do it ... First what control should i use dg, lvor ..?
And how to declare this all months with days...

Plz help how to start it?

I'd use a DataGrid and to keep it simple stupid have a class that represents the room and every day of the month. Then write some code which returns a collection of the class. There would be a lot smarter ways to approach this but sometimes keeping it simple is the most maintainable.

You may also look at your database structure because sometime guests may stay in one room for 2 nights and a luxury room for 1 night. You may want to store this data night by night and not from-to date.

Good luck with it. Micros Fidelio are one of the most fierce competitors your every likely to bump into.

Architecture is extensible, code is minimal.

i will have a data_from, data_to in, number_of_people register table the colors will declare in other one i think and the room in other and buildings in other :/
In C# i will have .cs files which represents entities and mapping classes for this entities .
But could u write some example how it could be? I Will really happy Wink | ;)

I heard somewhere that lv will be better than dg...

BTW if I will use Flunet NHibernate and LINQ NH + mapping should I make in My MySQL Server relations on Entities (i mean in MySQL Server) or just make entities and PK's but in VS Entities .cs files and mapping it will be enough ?:
for example:

public class ClientMap : ClassMap<Client>
    {
        public ClientMap()
        {
            Id(x => x.Id).Column("client_id");
            Map(x => x.FirstName).Column("imie");
            Map(x => x.LastName).Column("nazwisko");
            Map(x => x.Created).Column("utworzony").Not.Nullable();
            Map(x => x.Updated).Column("aktualizacja");
            Map(x => x.Deleted).Column("Usuniety");

            HasMany(x => x.Rooms)
                .Access.Property()
                .Cascade.All()
                .LazyLoad()
                .KeyColumn("client_id");

            Table("klient");
        }}

I don't have any examples at hand but there are a few open source PMS systems out there so do a search and see how they have approached the problem. It's a fundamental requirement for both PMS and CRS systems.

Architecture is extensible, code is minimal.

in my application once a client connected i run the following code

byte[] buffer = new byte[512];
       while (soc.Connected)
       {
           try
           {
               soc.Receive(buffer);
               string encodedstr = Encoding.UTF8.GetString(buffer);
               this.Invoke(update, new object[] { encodedstr });
               buffer.Initialize();
           }
           catch (Exception)
           {
               if ((soc != null) && (soc.Connected))
               {
                   soc.Disconnect(false);
               }
           }
       }

but when the client disconnected by closing or accidentally the server runs infinite loop with the
last content sent by the client. so my textbox infinitely append the last data to it's content.

so i want to know if ther is any other better way of receiving data from client continuously to solve this problem.

That is how TCP/IP works.

The only sure way to validate if someone is on the other end is by sending something, sometimes quite a bit of something.

The way servers commonly solve the problem is that they require clients to send them data during a given time period. If the client fails to send anything then the server disconnects.

Another way is to explicitly send a do nothing message to which the other end must respond within a given time period. If they don't respond then disconnect (obviously disconnect as well if there is a delivery failure.)

None of the information in your post is correct as far as using a socket class is concerned and applies only to writing your own TCP/IP stack.
