Hey, me again, just wondering iff anyone knows how to get rid of the console window... Im making my forms dynamically, using a console application, but if the console window shows, it isnt as attractive...

I think you get what you want, if you create a Windows application and fill the Main-method with some other code before showing a form.
<br />
static void Main() <br />
{<br />
System.Windows.Forms.Application.Run(new MainForm());<br />
}<br />

I know, but i made a console program, its an irc server, and now i want to make it use a tray icon, so you can tell tyhe status of the server, but i already coded 75% of it in console, and i cba to switch to a windows application... Isnt there a compiler directive to hide the console?

Don't know a direct way to do this, cause I never coded a console application with .NET. Maybe you could use some API methods to hide the console window.
Is it so complicated to copy the "console" code to a Windows Application to reach the effect you want.?

yes. One, is file size, and i dont want the program to be loading all the stuff i dont need. File size saves time (downloading and running) and saving time means more users (most likley me and a bunch of friends) will want it to be fast, small, etc.
Would it be possible to grab the process and set it to hid somehow through that?

OMG, this is my second time writing this, cause last time i wasnt logged in, and i clicked submit, and it said i needed to login, so i hit back to copy/paste my post into notepad, and it was gone... arrgh. Anyways:
I have a class, lets call it "IrcBot". Now, i instanciate it like this:
IrcBot mybot = new IrcBot("server","channel","nick");
now, in my main class, i make a thread (or 10) all going to the same, or different irc servers... like this:
Thread t = new Thread(new ThreadStart(mybot.connect));<br />
t.Start();
seeing as there is no way to terminate the connection from the bot to the irc server, i cant terminate the thread, cause the thread is still doing something... In english, when i do t.Abort(); it doesnt stop and the bot is still in the irc server in that channel... How can i force the thread to stop regardless of whether its doing something or not?
Thanks for the help :P

What i did now, is i made an instance of a timer within my thread, and set the interval to 1 millisecond...
System.timers.timer t = new System.timers.timer(1);
Then i made the event handler thing
t.Elapsed += new System.Timers.ElapsedEventHandler(t_Elapsed);
and the elapsed method looks like this:
private void t_Elapsed(object sender, System.Timers.ElapsedEventArgs e)<br />
{<br />
if(System.Threading.Thread.CurrentThread.ThreadState.Equals(System.Threading.ThreadState.AbortRequested))<br />
{<br />
connection.Disconnect("Gotta go!");<br />
} <br />
}
Why wont that terminate the connection & die when i call abort from the main thread?
//Otis
|
|
|
|
|
Well, i finally figured it out...
In the IrcBot class, i made the variable holding the connection public. Then, before i started the thread, i grabbed that connection, and stored it in a variable. Then when i want to abort the thread, i use the variable and disconnect, and then abort  It is kinda crude, but it works

What would you suggest as the easiest way of converting a stream to a string?
|
|
|
|
|
|
System.Web.UI.WebControls.Label myLabel = new System.Web.UI.WebControls.Label();
myLabel.Text = "Enter Client ID";
this.Controls.Add(myLabel);
This is not working .. any help..please
|
|
|
|
|
What do you mean by "doesn't work" (what kind of exception are you getting?). I believe you need to set other properties of the newly created label, such as location and size. I usually set the following and never have a problem:
Name
Location
Size
BackColor
ForeColor
Hope this helps

Hi Guys,
I want to port my old client-server programme from VB6 to C#, and I want to use some new stuff from the .NET Framework. Especially how the two programmes communicate with eachother.
Verbodrome (that is how the programme is called) is used in classrooms, for example 20 students are working on it, and the teacher can centrally view the state of each student. In VB6 this was done with a TCP/IP connection but since the server took a lot of processing load (serving 20 clients) it just wasn't scalable.
So what I want to do is this:
- An object 'session', wich stores the various questions. It is cloned for every client so the 'session' object also stores the answers the students gave.
It is hosted on the server with following advantages. 1) When the students quit their session, the information is still stored on the server, and next time they log on they can work further on their previous session, and the teacher can view the progress the student is making.  2) Every time the student gives a new answer, the statistics on the server screen are real-time updated (thats where the events come in).
There are various other objects in the project, but all with similair purposes. So i tried to get some basic programme up and running. I constructed a CAO server, wich could fire events to the remote machine (where they were handeled. First problem: CAO servers don't seem to work due to some SOAPSUDS.EXE bug  , so i tried a class-factory (a SAO wich generates the necessary 'new session' classes), but when i tried fire my server event, the client gave an error that this wasn't deserialisable... So I adjusted the security settings (1.0 -> 1.1 troubles), but that either was no good. 
So now I am asking the outside world, because I really tried everything. I'm a good programmer in VB6 (Verbodrome counts over 58.000 lines) but I am relatively new to C# but I know the basics. If anyone could give me a clue or try to get a class to work that would serve as an example to me, I would greatly appreciate it.
Every goodbye is the birth of a memory

Creating double posts with in the same forum is frowned upon even when using a different login. People will probably just keep ignoring it until you delete the offending posts and re-phrase your question.

P.S. Look at some of the articles here on Code Project for threads/threading. Some have the basics for making a threded chat server, which can be modified for communication between clients / server.

I double posted it because
- The first time 'The Code Project' website thought i wasn't logged in
- The (emot)icons didn't work: X|X| looks a bit strange...
And i can't delete the first question because I wasn't logged in so the system doens't know it's ... I can of course delete the second post, but thereby eliminating the reason why I posted it again

But on both posts your name or intials show up as the user name. How did you do that?

Hi,
Heath had mentioned using a Dataset.Merge for a returned dataset from web service to client but I can't seem to find any property called Merge.
Where do I find it ?
Thanks,
JJ

It's clearly there:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpref/html/frlrfSystemDataDataSetClassMergeTopic2.asp
Are you sure you declared it as System.Data.Dataset? And not as a datatable or something like it?

Hi,
I need to test if an Array object is empty. What's the best way to do this? Also how do you determine if an object exists?
Thanks,
JJ

Do you mean contains no elements, or that all the elements are null?
The Length property will tell you how many elements are in an array.
If you mean the second option then you would have to iterate over the array testing for null on each element.
MrJJKoolJ wrote:

I don't understand this at all. If an object exists you will have a reference to it somewhere. Although, sometime objects will exist that you don't have a reference to anymore and by that time it is too late because the garbage collector will be clearing it out soon anyway.

On the object question, I need to know how to test if an object exists for a reference.
Thanks,
JJ

bool allNull = true;
foreach(object element in myArray)
{
if (element != null)
{
allNull=false;
break;
}
}
At the end of this code snippit, allNull will be true if all the elements of the array are null. It will also be true if the array is of zero length (so you might need to test for that condition also)

Okay, a bit of confused terminology here. You want to tell if a "variable" references an object or not. For that, it looks like Otis_69 responded with the correct answer for that.
Does this help?

To determine if the object exists you do this:
if(yourobject != null)<br />
{<br />
}<br />
else<br />
{<br />
}
I hope you have the right word (exists) because an object that doesnt exist is just a name. If it does exist, then it has a refrence to a location in memory that holds the object.
To test if the array is empty, do as the guy before me said, use yourarray.length() because by empty, i assume you mean the name exists, which holds a refrence to the object (so the object exists) but there is no data in the elements...
