Dragging form / slider etc. stops execution

[Rick H]

My code needs to transmit regular packets onto a serial bus, however when the user holds the mouse down on a slider etc. then the transmit function stops until they let go

Is there a clever way to continue processing whilst this is happening?

I am thinking multithreading might be a way around this problem but is there a simpler way?

Cheers

Any ideas?

Kinda a cheap wannabe multithreading idea, as I don't actually know much about it, but, could you put the function that sends the data to the serial port in a seperate dll? That should not be affected by whatever the main app is doing, assuming you don't wait for a callback or anything...

I'd wondered about that, or maybe and ocx. I have a few questions about this though,

In my main code I initilise the serial card via a dll (supplied with the card) I then use the dll functions to transmit / recieve, clear the buffer etc.

I will need to access this serial dll in my new dll/ocx. This needs to be independant of my main code (so I can not call functions in the main code) how do I "share" this dll?

Just call the serial dll from your new dll/ocx. If you put all the functions needed in your new dll/ocx, then you wouldn't need to share it, not that I am sure that the problem with that would be anyway.
