Hi all,
I used the Timer class to make a tick event in specific interval, in my C# .Net service. My attempt as follows.
private System.Timers.Timer TimerTicker = null;
public RfService()
{
InitializeComponent();
const double INTERVAL = 10000;
TimerTicker = new System.Timers.Timer( INTERVAL );
TimerTicker.Elapsed += new ElapsedEventHandler( this.ServiceTimer_Tick );
}
Here, ServiceTimer_Tick() do my processing part.
My question is this. Immediately after starting my service start to count the tick on each 10 seconds and do the processing. That's fine, and work it well.
But, I want to hold the tick for 2 minutes immediately after starting the service and then do the 10 seconds interval process. That mean only the first time I want to hold the tick for 2 minutes.
I think it is clear for you. How can I do this. I'm really new for C#. Specially on threading, because I found that using threading I can do that.... 
Thanks
I appreciate your help all the time...

It's pretty straightforward. Set the interval to whatever you want it to be for the first tick, and in ServiceTimer_Tick, set the interval property of the timer to whatever you want it to be afer that.

If I get you correctly, you ask me to use two tick event. Yes I think that. But one of tick event execute only one time, stop it after 2 minute.
And also I do all those things in constructor method. 
I appreciate your help all the time...

No, not even remotely.
The timer has an interval property. Inside your tick event, set the Interval property to the value you want it to be after the first time it fires.
All I am suggesting is you do something like
Timer.Interval = 2000; // 2 seconds
inside the tick event.

What's the actual issue ? Sounds to me like Vista is blocking your sockets. If it won't build under vista, then post your errors.

OK, so your program doesn't work in Vista. Welcome to the club. You need to learn how vista permissions work and investigate how to change your code so it works in Vista.

I'm sure you are. At this point, I'm not sure how you expect that I'd have any idea of what your program does, what the error is, or anything else that I could use to diagnose the problem. I'm also logging off for dinner, why not get the exact text of your error message, and type it into google ?

OK - well, I guarentee that I have absolutely no idea what's going on, how can I ? Have you checked the event log ?
Worst case - get a dev environment in Vista, and debug it to see what line it fails on.

Why should he do that? SO you can pester him in private!?
People here are volunteers and the answers go on the forum so that if someone with a similar problem arrives they can see there is already a solution. Asking for a private email correspondance is somewhat inconsiderate of other users. If you want private assistance then pay for it. If you want free then respect the people who are available to help.

You waited about 45 minutes for a reply! Get a grip. If you want a response that fast pay for it. People here are volunteers who spend their spare time to help. They are NOT at your beck-and-call whenever you want them.
You were given a suggestion to follow up, but it seems you were too lazy and started to pester people instead. Just to recap, the suggestion was: "You need to learn how vista permissions work and investigate how to change your code so it works in Vista."

loading pages should be showed before the next page data are loaded. help me friends.

1 - post in the right forum ( asp.net )
2 - if you don't want to use the technology that solves your issue, then I guess you just have to live with it. AJAX is the ONLY way to show something on your page while the server is in the process of sending new data.

Hello
I am new to XmlSerializing and I got a problem when trying to serialize a nullable int.
The thing I serialize look like this
private int? length;<br />
public int? Length {<br />
get { return this.length; }<br />
set { this.length = value; } }
But when I serialize this, and it is null, the output looks like this:
<Length d3p1:nil="true" xmlns:d3p1="http://www.w3.org/2001/XMLSchema-instance" />
What I want it to do is, when the int is null, I want it to be ignored and thereby not having any output to my xml-file.
I could make my int to a string and then convert the string to an int whenever I need, but that doesnt seem to be a good solution to me.
So, does any of you know a way to XmlSerialize an int and then if it is null, it shouldt be showed in the xml-file, or a good article/something?

To play a AVI stream I use this code in c#:
const uint WS_CHILD = 0x40000000;
const uint WS_VISIBLE = 0x10000000;
const int ACM_OPEN = 0x400 + 100;
const int ACM_PLAY = 0x400 + 101;
IntPtr handle = CreateWindowExW(
0,
"SysAnimate32",
null,
WS_CHILD + WS_VISIBLE,
0,
0,
300,
300,
windowHandle,
IntPtr.Zero,
IntPtr.Zero,
IntPtr.Zero);
SendMessageW(handle, ACM_OPEN, streamhandle, id);
SendMessageW(handle, ACM_PLAY, -1, -1);
...
DestroyWindow(handle)
This works fine in XP, 2003,... But in Vista and Longhorn, the stream is loaded (the background is painted), but not every AVI is played, some are, and some are not. Is there something I missed?

Hi,
just a guess, but what about codecs? Do you have the same codecs installed? Do the movies play with Media Player?
Cheers,
Chris

I do not thing codecs are the problem. Let's take the example of shell32.dll. Here the AVI resource with id 165 is playing in Vista, but the one with id 162 (the Avi one sees when files and/or folders are deleted) is not. When I delete a folder, I do see the animation (so I presume the codec is installed); when I want to play the animation in another window, I only see the background.

I want to show a dialog box, that I've created in visual studio when data has arrived from a socket.
I'm using Socket.BeginRecive and passing it a callback method OnDataRecieved.
When I try to show a dialog to get user input upon data received it. The dialog works fine when it's opened via a button on the main form.
This is the code I'm using to get the form.
<br />
RestoreDeleteDialog form = new RestoreDeleteDialog();<br />
form.ShowDialog();<br />
After I've called BeginReceive() and the event method has ended (ie it's stopped executing the code I've written and is sitting their waiting for an event such as button click or an incomming packet) it will crash with this error:
InvalidOperationException
"The Undo operation encountered a context that is different from what was applied in the corresponding Set operation. The possible cause is that a context was Set on the thread and not reverted(undone)."
If I change the above code to form.Show(), ie so the form is not modal, (which is what I want the, as I don't want the netcode blocking for user input) form will not load and will just be a white window. I've put break points in the code that I've written and there are no infinite loops or anything like that. This happens after the constructor and the form load events have run, when my code has exited.
I'm thinking this problem is being caused by a problem threading, as BeginRecieve() is presumably going to be running in another thread, but I'm not really sure about the inner workings of the non-blocking socket methods, or about how I might spawn the dialog off in another thread with out it causing this error.
Anyone got any ideas?

Hello
When drawing on a PictureBox, I try to do something but I don't know if it's possible
In fact I try to do TWO operation in the same process
1- Update the ground image of my PB drawing some new elements using one graphics
2- Add some temporary elements on another layer using another graphics
Below is my code
At the end I do
this.pb_cont.Image = cityImage;
This will save my new ground image but it also hide whatever I draw on the other Graphics
How can I avoid that ?
Is it possible to re apply graphicsT content on the PB
With my poor knowledge I thought to do this :
GraphicsState OldG = graphicsT.Save();
this.pb_cont.Image = cityImage;
graphicsT.Restore(OldG);
BUT the compile do not even recognize GraphicsState ??
What is my mistake ?
Thank for your help
private void DrawCityList(DataSet cityList,SolidBrush AskBrush,int size)
{
cityImage = new Bitmap(this.pb_cont.Image);
Graphics graphics = Graphics.FromImage(cityImage);
Graphics graphicsT = pb_cont.CreateGraphics();
foreach (AddrList cAdr in AddrLst)
{
graphics.DrawEllipse(Pens.Blue, cAdr.X - 1, cAdr.Y - 1, 2, 2);
if (cAdr.active)
{
if (AskBrush != null)
{
graphicsT.FillEllipse(AskBrush, tX - size/2, tY - size/2, size, size);
}
}
}
this.pb_cont.Image
