So, what does thread execute before it stores a log message? Also, how are you logging your messages?

Nothing else.The first line of the thread is to store a message.
George L. Jackson wrote: Also, how are you logging your messages?
A log host service application exists in my system. All the threads in my main program (a service of XP) send log messages to a log client inside the main program(first into a quue). The log client send to log host by remoting FIFO. Both the client and the host are working after a certain thread hanged up.
Thank you

Does each thread access the queue directly? Are you using a synchronized queue? Also, you probably know this already, threads don't always start executing in the same order that you executed Thread.Start.

Yes, each thread access the thread directly but synchronized.

As you have pointed out, I have taken this point into condsideration. But, the fact is although my program rarely hangs up, it happened when some factors occured at the same time.

I would like to continue this thread because it is not solved yet.
I realize these days that there may be some reasons in the total threads in my application. In a app., what should the total number of threads be? Here threads include all thread invoked by mechanisim such BeginInove and Thread.Start().
In my appl., the active threads number ranges from 40 to more than 60. I don't think this is proper, but threads number under my control is just no more than 5. Who should be responsible for all these threads? Many remoting process are undergone in my application.
Thank you!

Hi all!. I have detected one problem with Agilent Vee 7.52 and .NET Framework 2.0. This morning my network did not work, and if I wanted to open a .vee file with some .NET objects, it taked a long time to open. Later, when the network worked, the file could be opened correctly.
Does anybody have this problem??
Thanks and regards.

Hi folks,
Background:
I am creating a control using VS2005 .NET Framework that reports on the progress of some background processes. There is no concept of data entry or selection here; the only user action is to scroll the list if required. The current implementation of this uses a ListBox-derived control with drawing code implemented in the DrawItem event handler. That code works (more or less) fine when the data that backs each item in the list is static. I have two items that change dynamically: a progress bar and a text field that must be able to change fairly quickly over time. The current implementation includes custom drawing code for the whole - there are no child controls.
My problem is that although I can change the value of the data field easily enough, all I can think of doing to make the ListBox aware of the change is to call Invalidate() for the whole control, and the paint events don't keep up, and the resulting effect is very jerky - tending in fact towards only updating once the progress reaches 100%
The reason for a global Invalidate is that I am not aware of anything in ListBox that enables me to discover where an individual item is on screen, so I can't paint it explicitly or do a bounded invalidate. I am wondering if ListView offers that ability, but can't see it if that's so.
So, to put the question straight: With an owner drawn list box/view, how to I tell the control that a (sub)item must be repainted now - preferably this instant - because the data backing it has changed?
Regards

The ListBox has a public GetItemRectangle[^] function which will tell you the bounds. You could put this one into the Invalidate call.
|
|
|
|
|
I eventually solved the problem using the List View SubItem Bounds property, which returns the bounds of the specific SubItem.
I check that the bounds are contained by the parent's ClientRectangle, to avoid invalidate calls for items that are invisible, then pass the Bounds into the Invalidate call as Robert suggested. This is still slightly flickery, but not too bad.
Thanks.

Does anyone know of a way to retrieve information from a Microsoft Wireless Optical Mouse? The Intellipoint software contains a signal strength and batery level monitor, I would really like to be able to query that information from within an application I am building.
Does anyone know of an API or DLL I can use to get at the information?
Thanks in advance!

Hi,
when I load an image using this
Bitmap bitmap = (Bitmap)Image.FromFile(pic.Path),
it is not possible to delete the file afterwards, unless you exit the program. I tried to call .Dispose() on the object, but it seems like a bug in the FromFile method.
I found out a workaround
Bitmap origbmp = new Bitmap(pic.Path);<br />
Bitmap bitmap = new Bitmap(origbmp);<br />
origbmp.Dispose(); .
I keep working with the copy of the original bitmap as it's not locked anymore.
But, loading an image using Bitmap's constructor, it's impossible to load animated GIFs as it seems that Bitmap doesn't support them.
Now, how can I use animated GIFs and other image formats AND be able to delete the file afterwards?
Thx 
Stefan

You are probably better of capturing your information on a worker thread. Notice you can't update the GUI from this worker thread, so you would have to get the data to the GUI thread somehow.
Some of the options are:
1) Share the data, do a lock when it is updated/read
2) Clone the data and send the data to the GUI though BeginInvoke
I can't say which one (or something completely different) is best, it comes down to the data and - not least - your personal taste.

Hi. This is the problem. Agilent Vee crash with .NET Threading... 
The other question is, only GUI stop or all program stop??? If only stop the gui, no problem, the most important its a second work...
Thank your for your ideas  .
Best Regards.
