Hi,
We have a c++ application that accesses many different modules. Each
of these modules is responsible for it's own
serialization. We have seperate olestorages for each of the
module. The main application hands over these storage
pointers to each module which then do whatever-they-want to
their respective storages. Everything is kept with in a single file.
Seperate storages for each module help tremendously because

I have a question regarding synchronization across multiple threads for a
Hashtable. Currently I have a Threadpool that is creating worker threads
based on requests to read/write to a hashtable. One function of the
Hashtable is to iterate through its keys, which apparently is inherently not
thread-safe. Other functions of the Hashtable include
adding/modifying/deleting.
To solve the synchronization issues I am doing two things:
1. Lock...

I have a C# Program where multiple threads will operate on a same Hashtable.
This Hashtable is synchronized by using Hashtable.Synchronized(myHashtable)
method, so no further Lock statements are used before adding, removing or
iterating the Hashtable. The program runs in a high workload environment.
After running a few days, now it suddenly catchs this Exception when
inserting a pair of key and object,

From what I understand, in ASP.NET, each HTTP requests is serviced by a separate thread. So if my code uses a static Class with shared members and properties, I can manage concurrent access by using something like the Monitor or ReaderWriterLock class. It is rather difficult to simulate multiple threads in a debug environment so I am hoping someone can enlighten me by telling me what happens in the following scenario?
A request is made to...

I want to make a class that will write data to a in memory table. This
class will be called by multiple threads. I'm hoping the table can stay
in memory between calls and all the call by the thread will have to do
is pass some data to be added to the table. Kinda like this class I
have to write to a log file.

Hi,
Here is the scenario. I have a list of IDs and there are multiple threads
trying to add/remove/read from this list. I can do in C#
1. create Hashtable hList = Hashtable.Synchronized(new Hashtable());
2. create ArrayList aList = ArrayList.Synchronized(new ArrayList());
3. create a string sList = "";
For 1 and 2, since the list is synced, many threads can directly

I have this Hashtable of Hashtables, and I'm accessing this object from
multiple threads, now the Hashtable object is thread safe for reading,
but not for writing, so I lock the object every time I need to write to
it, but now it occurred to me that maybe I could just lock one of the
Hashtables inside without locking the entire object, but then I thought
maybe some thread could instruct the outside Hashtable to remove an

hi
i'm downloading a single file using multiple threads...
how can i specify a particular range of bytes alone from a single
large file... for example say if i need only bytes ranging from
500000 to 3200000 of a file whose size is say 20MB...
how do i request a download which starts directly at 500000th byte...
thank u
cheers

Much to my surprised the code below compiled and ran. I just don't know
enough about threading to know for sure if this is too good to be true.
I'm attempting to isolate the Hashtable lock to "row level", the whys aren't
important at this time. Does this code actually do what I want?

using System.Collections;
using System.Collections.Generic;
