funny error

[marvinklein]

i have a folderwatch class that monitors a folder for created files.
when a file is created, it triggers an event. in this case i call a function on my main form which tries to add a node to a treeview on the main form.
i get this error: "the action being performed on the control cannot be called from the specified thread" and then something about using control.invoke and control.begininvoke.

any ideas whatsoever????

i still don't understand why there is this threading problem. if anybody could explain, that would be nice...

The main problem with threading is that any obj created on the main thread can't be shown on the main thread ...
