passing data between threads

Hi, I have multi-threaded application that requires one particular thread
(Non-Form based) to receive data from other threads. I know how to pass
control to Form Threads, but I believe there's no way to pass to Non-Form
Threads. So the only two solutions I can think of to handle this situation
is to (1) Keep the Non-Form Thread as is and set up a polling method to
watch for shared variables and respond appropriately, or (2) change the
Class to a Form so I can pass control to it from other threads.

Is there any other (and hopefully easier) way besides two way approaches
above??

we seem to be going in circles here.

your code needs some way to "listen". an event driven model makes the
most sense (if this is truly a single application and not several).

if I correctly your scenario, you will have a variable number of
clients. this means that if you choose the polling approach, you will
possibly have to poll a variable number of objects. in general polling
is a bad idea and in your instance would be a VERY bad idea since it
will create a lot of excess work on the thread, etc. this is why
mutexes and semaphores were suggested.

Ken Tucker's suggestion about wrapping the thread in a class is
EXCELLENT advice -- you should ALWAYS do this (i.e. his advice extends
beyond your current needs.

at this point, SAMPLE CODE would be helpful! your description is
beginning to sound like MULTIPLE PROCESSES and not multiple threads.
Code would be most helpful.

to avoid spinning you in circles with generalities, if you have code
that gives you "illegal cross thread operation" errors, you are on the
right path -- if you post that code here, we can help you make it
work...

Hi, I've seen a walkthrough for passing data from a setup project to a custom action (an application) with an InstallClass. I am curious though--can the data also be intercepted by a custom action defined as a vbscript? If so, does anyone have any idea how it would be accomplished? Thanks! Rob Oliver

Hi, In my application I get lots of different sorts of information from databases. As such, a lot of information is stored in DataSets and DataTable objects. Up until now, I have been passing around chunks of data in DataTables/DataSets, simply because that was the format that they were in when the data was taken from the database. Now, I know this maybe a pretty silly question with a standard "it depends" answer, but I'm going to...

I have a htm page where I need to pass some data to an aspx page as a means of sending data to the database. I don't need to see the aspx page so I was going to put it in a hidden iframe. This works real good. Since I don't need the aspx page to do any postback, is there a way to pass a parameter to it with out it finishing the round trip back to the htm page? Thanks. -- moondaddy@newsgroup.nospam
