Hi,

I have a main form frmMain, frmMain creates an instance of a class MyThread.
MyThread creates a thread and countiously reads a comport for some string
data.
When a certain string is recieved MyThread fires an event OnDataRecieved.
frmMain has an eventhandeler implemented (DataRecieved) for the
MyThread.OnDataRecieved event.

So finally my question
Is it safe to update textbox and label values from within
frmMain.DataRecieved ?

Any help or hints greatly appriciated.

regards,
Leo

Absolutely not. It's not safe in the CF or full framework. Use
Control.Invoke to marshal a call back to the primary UI thread and update
from there.

Ok, I see

I understand I need to do something like this from MyThread :

frmMain.Invoke(new Eventhandler(aGuiUpdateMethodeInfrmMain);
right?

If this is correct is there a more 'dynamic' way to do the call. I do not
like the idea tha MyThread needs to know both frmMain and
aGuiUpdateMethodeInfrmMain.

Could mabe MyThread take a inparameter ('methode to invkoke'?) when
constructed ? Tried this, but with no luck so far.
