You can use the app.config file to store values or the settings file[^]

or any other file for that matter.

yeee I find it and it does a great job indeed.
ha. I must now find a way to integrate an array there.
Here is How To Save Inside Your App !
1. select a button in the designer, open Properties for it, and see the first property named "ApplicationSettings". Click on the + sign to open his sub-properties. At the "text" property click the down arrow and it appear a little box-window. There inside click on the "(New...)".
2. At this stage, you should see a window named "New Application Setting". Change the name to "mySetting", Scope = User, Default Value = "aha". Click Ok.
3. (optional) To verify if all is how you want to be, open Solution Explorer - Properties-Settings.settings. A new window appear and open the Settings tab from the left. You will see there all your custom settings.
A little advice: select the button in the designer, go to it's properties again, and at it's Name property verify if it has the "aha" value there. It must be there, because you set it in the Default Value, last time. 
4. In the code for that button, write this:
private void buttonSave_Click(object sender, EventArgs e)
{
if (buttonRestore.Text == "aha" )
{
buttonRestore.Text = "-!aha!-";
}
else
{
buttonRestore.Text = "aha";
}
Properties.Settings.Default.Save();
}
5. Run your app, click the button to change it's appearance, and restart app.
VOILA!

I think I find a BUG for this "ApplicationSettings".
It's about after I compile the program.
If I move the myprogram.exe on another folder or partition, the values that I originally stored, they disappear.
It only retain the information data if is Not moved.
WHERE THAT DATA GO, AFTER ALL?
Is inside it, really?
Or is somewhere stored in some temp file?
thanks.

If you look at the documentation for "Properties.Settings.Default" you will find it is saved in a file called "<yourappname>.exe.config" in the same directory as the application executable (i.e. ".../bin/debug" or ".../bin/release") If you copy this file when you copy your executable, you will be fine. The only other option is to store it in the registry, but this is not recommended:
1) Registry use is being discouraged, as it make it too big and cumbersome.
2) It is difficult to move your settings from one machine to another.
3) It is impossible to transparently have different settings for debug and release versions of your software.

I am using Visual Studio Express Edition 2008 and want to use a timer from "System.Timers".
I don't know how to create the Event without any 'Tick'-Event when the timer interval elapses.
There is no 'Tick' event in the timers-pull down menu as described in different manuals and forums.
There is one example on
C-SharpCorner
timer1.Interval = 5000;
timer1.Enabled = true;
timer1.Tick += new System.EventHandler (OnTimerEvent);
So how can I create a method, that's been processed when the interval elapsed ?

There are several Timer classes in .NET and each of them has a different set of properties and events.
That article is about System.Windows.Forms.Timer, which are very good for supporting periodic GUI updates, such as a clock display.

Yes, in the meantime I found something about the different timers.
Since I don't use Windows.Forms, but XNA, I guess I rather should use System.Threading-timer, right ?
Is there any example for those timers ?

|
|
|
yes
yes
Google!

OK, thanks !
Good night.

The System.Timers.Timer class has an Elapsed event instead of a Tick event.
timer1.Elapsed += new System.Timers.ElapsedEventHandler(Timer1_Elapsed);
void Timer1_Elapsed(object sender, System.Timers.ElapsedEventArgs e)
{
}
|
|

OK, in principle that works. Thanks !
Now I have to work on the threading problem I got within my application...

I'm developing a chat server and a chat client in C#.
My client application is a GUI with some TabControls, ListBoxes, Buttons, Textboxes and Labels. The client also has a separate thread to detect messages sent from the server.
One of the messages sent from the server is to display what other users are available to chat with.
I can receive the other users IP-address and store them in a collection. When this is done I send an event from the thread method to the Client's GUI's Form-class and run a method to display the users.
That method is just clearing all items in a ListBox and insert all IP-addresses into the ListBox by foreach-looping the collection sent as a parameter from the event.
When I try this an: InvalidOperationException is thrown. The exception messages basically says this (translated from Swedish):
"The actions between threads are not valid. The control lstOtherUsers (the name of the ListBox) are received from an other thread that it was created in"
I can understand the problem why I cannot update the Item collection in my ListBox from an other thread when the ListBox was created in an other thread. But how shall I solve this?

What your experiencing is called Invalid cross-thread operations.

Hi,
Here[^] are my recommendations.

Controls can only be accessed from the thread they were created in. To access controls from other threads, use InvokeRequired property and Invoke method:
delegate void AddListItemCallback(ListViewItem item);
private void AddListItem(ListViewItem item)
{
if (this.ListView1.InvokeRequired) {
AddListItemCallback cb = new AddListItemCallback(AddListItem);
this.ListView1.Invoke(cb, new object[] { item } );
} else {
this.Items.Add(item);
}
}
InvokeRequired returns false if the calling thread is the same thread as the one the control was created in, and true otherwise.

I'm having trouble creating a query that only takes a specific number of players from each position.
My goal is to create a query that takes all offensive positions by OVR (and certain number of players at each position), add up their OVR (a player property) and divide it by the number of players that I took the OVR from (to obtain the average rating). So, basically, I'm trying to obtain the average rating of all "starters" on offense. These starters are determined by their OVR rating (where the highest OVR is a starter) as well as the number I'd assign to each position to determine how many starters are at each position (so the player with the second highest OVR is another starter).
This is the code I've come up with so far:
[code]
public int OffenseRatingCalc
{
get
{
var offense = from p in Players
where p.position == PlayerPosition.QB ||
p.position == PlayerPosition.RB ||
p.position == PlayerPosition.WR ||
p.position == PlayerPosition.TE ||
p.position == PlayerPosition.LT ||
p.position == PlayerPosition.LG ||
p.position == PlayerPosition.C ||
p.position == PlayerPosition.RG ||
p.position == PlayerPosition.RT
orderby p.position
select p;
var oR = offense.Average((p) => p.OVR);
OffenseRating = Convert.ToInt32(oR);
return OffenseRating;
}
}
[/code]
The player property "position" is a PlayerPosition type--an enum that contains the following:
[code]
public enum PlayerPosition { QB, RB, WR, TE, LT, LG, C, RG, RT, DE, DT, OLB, MLB, CB, FS, SS }[/code]
OVR is also a property of the Player class.
Right now, the code works but it takes all players from each position on offense. How do I take only a specific number of players from each position (for example, 1 from QB and 2 from WR) to only be included in finding the average? So, the highest OVR at QB is chosen, and the two players with the highest OVR at WR are chosen.

how can a make video clip in c# like the clip that can be made in flash????????????????
|
|
|
|
|
Why create a animation engine when you can just use Flash??
|
|
|
|
|
Making a video clip in C# is veri simple......... just like what a movie maker does...... there are SDks available for it......... but be specific next time about what you want to do next time you post a question cause it differs in web and windows somewhat beside with your requirements........
for web there are two ways of doing it when capturing an image from a cam
1. theres a protocol called cgi. it has a file with extension .cgi for which you need to reach. the server must have an static ip address. use that ip address and location of the file and provide the same to the com component of flash media player or windows media player and just 'khul ja sim sim' or 'abra ka dabra' and the video just plays on your web page where the control is placed or just open the file by providing the url(ip+filename.cgi after hosting it on the server) to IE6+(on firefox u'll need to refresh it for next frame)
1. create a timer that fetches a .jpg image after every of your time interval from the url(see above) and provide the image(on your local machine) to any com player as media or flash or just use simple image box to display the .jpg and your movie plays with frames changing after every time interval just as in like a movie. keep the time interval short for better performance only if you have good internet speed. to fetch the jpg file just open the same url(as above) with extension .jpg rather than .cgi.
