Please look at the code:
I am using three such timer and callback functions,but it seems timers are always running when I close application also.
timer = new System.Threading.Timer(new TimerCallback(OnNextMinute), null,
Timeout.Infinite, Timeout.Infinite);
timer.Start()
public void onNextMinute()
{
}
~Class
{
timer.dispose();
}
How to make sure that it stops running when my app is closed.
appreciate immediate help as it is urgent.
Thanks in advance,
|

Use the windows timer instead of the threading one. Have your window closed event call Stop on the timers. Either of those things should work. If your timer is still going, then your app is still running.

There is no guarantee that the finalizer (~) will be run when the application ends. The finalizer is called after that the garbage collector has recognised that the object isn't used any more. An object with a finalizer is placed in a queue where a background thread will be calling the finalizer, but as your object is still used when the application ends, it will never make the queue.
As you have a resource that needs to be freed, you should implement the IDisposable interface so that you can call the Dispose method on the object to free the resources. Just as you are calling the Dispose method of the Timer object to make it free it's resources.

Thanks a lot for prompt replies,I will try to dispose the timer first to stop app from running..

I implemented IDisposable interface , but still not able to release resources.
I am trying to dispose the timer in Dispose Method and calling the Dispose Method in the Main Class event where I want to end the application.
But my app is crashed at the Dispose Method with StackOverflowException at
timer.Dispose().
Please help me...

A stack overflow usually means that you have "accomplished" an infinite recursive call.
What does your code look like?

I am just giving part of code ,main function of this class is when the user request a file to download, file is broken into chunks,the chunks are added to PendingChunks,the PendingChunks are updated in timer ,the callBack function gets the ChunkAddress of the requested pendingchunks from the server .
public Class:IDisposable
{
Class{
ArrayList PendingChunks=new ArrayList();
timer2 = new System.Threading.Timer(new TimerCallback(getAddressfromServer), null, Timeout.Infinite, Timeout.Infinite);
StartTimer();
}
public void getAddressfromServer(object state)
{
getChunkAddress(PendingChunks)
}
const long TIMER_INTERVAL = 10000L;
private void StartTimer()
{
timer.Change(0, TIMER_INTERVAL);
}
}
public void Dispose()
{
Dispose(true);
GC.SuppressFinalize(this);
}
protected virtual void Dispose(bool disposing)
{
if (!disposed)
{
if (disposing)
{
timer.dispose(); }
disposed = true;
}
}
public void getChunkAddress(ArrayList chnkList)
{
ArrayList chnkAddrList=null;
Chunk c=null;
ChunkAddress chnkAdd;
chnkAddrList = HTTPClass.httpGetChunks(chnkList);
if (chnkAddrList != null)
{
for (int j = 0; j < chnkList.Count; j++)
{
c = (Chunk)chnkList[j];
for (int i = 0; i < chnkAddrList.Count; i++)
{
c.chnkAddress = (ChunkAddress)chnkAddrList[i];
}
}
}

The code that you show looks basically correct. I can't say anything about the actual code that you use, as you won't show it.
Where do you dispose the object?

I am disposing the timer in public void virtual Dispose Method

Sorry I have no idea how to dispose the object, can u please tell me?

You just call the Dispose method.
This should usually be done by the object that contains the reference to the object to dispose. If you for instance have put the object in a form, that form would call Dispose on the object when the form is closing.

As you said I have a recursive loop because I am not stopping to get Chunk Address untill I cleared the PendingChunks ArrayList,may be that is Cause?
Yes I have Called Dispose method in an another class ,triggered by Application Shutdown event of Form,
like this:
using(Class1 c=new Class1)
{
c.Dispose();
}
Is it correct?
Do I need to use using method?or just call Dispose Method?

Then you are creating a new object and dispose that, that doesn't dispose the object that you use in the rest of the code.

Hello everyone,
Why on earth I am getting this message? Everything was working just fine till yesterday and all of the sudden nothing works and I get this Warning and nothing works!
Warning 1 'System.Runtime.InteropServices.UCOMIMoniker' is obsolete: 'Use System.Runtime.InteropServices.ComTypes.IMoniker instead. http://go.microsoft.com/fwlink/?linkid=14202' C:\Documents and Settings\miyaoo\Desktop\directshownet\DirectShow\DShowNET\DsDevice.cs
I have looked at the suggested web address and I get this regarding this error.
System.Runtime.InteropServices.UCOMITypeInfo (Type Obsoleted)
Message: Use System.Runtime.InteropServices.ComTypes.ITypeInfo instead.
I checked the line suggested in the warning and this is what I have.
private static string GetFriendlyName( UCOMIMoniker mon )
what am I suppose to change it to?!!!
Thanx in advance for your help or suggestion.

" Use System.Runtime.InteropServices.ComTypes.ITypeInfo instead"
It means, the old one will work, but going forward, it may not on a future version of the framework, and today, they are suggesting there's a better way.

Hello Christian,
Thanx for the reply. But everything was working just fine yesterday and I have not change any code since! By the way, since this message started poping up things are not working the way they should be.
I might sound silly but I have no clue what so ever why this message started to pop-up and that is why I am asking. So, could you be more specific and think of me as some one new in this area with limited knowledge.
Thank you for your time,
Khoramdin

I really don't have more to add. You get that warning if you update the version of the framework you're compiling against ( that is, if you change IDE ), and you're using methods that are deprecated.
A google of the error message will probably give you more focused info, from other people with the exact same problem.

Hello,
Thanx for all the information. That is why I am puzzled. I didn't change my IDE. I simply went to bed and everything was working and now that I am back on my computer it is not working.
Trust me when I tell you I am reading about my problem as I am asking for help from the people on the site. I am not waiting for someone else to come and solve my problem. All I am asking is information or suggestion to help me out in my search.
Thanx for your time and have a great day,
Khoramdin

When I try to do a Graphics.FillRectangle() with a new SolidBrush(Color.Red) I get a filled rectangle as expected.
When I try to do this, though:
Color myColor = Color.Red;
...
Graphics.FillRectangle(.... new SolidBrush(myColor), ..)
it fails to draw any color at all. So what do I have to do to convert my stored color into the value it needs to properly draw the color?? I'm using stored colors because I'm exposing the three colors in the Designer.
Thanks.

It must be something else in the call to FillRectangle. I use the same approach you are all the time, without problems.

You shouldn't do this, you should do:
using (SolidBrush theBrush = new SolidBrush(myColor)
{
Graphics.FillRectangle...
}
so that it's Dispose method is called right away. You're leaking GDI resources here.

Hi Christian,
I plan on implementing that. I'm just running quick deployment to test out why the variable input isn't working. Then I'll go back to the original code that handles the GDI resources correctly.
So have you any thoughts on why I'm not getting my colors?
Michael

I never worked with the using "region"(don't know whats the real expression) and now I'm currious about it.

Does that mean that you would not need to call "theBrush.Dispose();"?
Are there more advantages by using "using"?
Thanks for your time and patients!
All the best,
Martin

the using keyword simply saves you from having to worry about calling dispose. That's all it does, is insert the code to call dispose, so you can see at the point of creation that an object will not leak.
