Been having problems with cross-thread violation in my program and been
researching on how I can get around it. I really want to continue using
ruby, because learning and using it has been fun, but if I can’t find
some solution I guess I have to drop it for now.
Basically I’m using a dll provided by a vendor to access the server to
get a live feed of data. I made a module using Ruby/DL to access the
function calls like logging on to the server and resquesting a snapshot
data or a session of a live feed of data. Everything has been working
great except my attempts to establish a live feed.
The live feed requires a callback function where the server will call
whenever new data is available. This is where I encounter cross-thread
I tried simple implementations of requesting a live feed and supplying a
callback function using Ruby/DL. I then just have an infinite loop to
keep the programming waiting. The callback is performed but after a
certain number of calls I get the cross-thread violation on
From what I read is this because the callback is initiated in another
thread apart from the ruby’s main thread? Even if this is the cause, I
still have no idea how I can remedy this. I tried using EventMachine
hoping that I could pass the pointer from the callback to some spawned
process but I eventually got the cross-thread violation.
Is there an approach I can use to solve this problem or do I just simply
give up and use something else. I’m hoping some of the gurus here can
give me some information on what I can do.
