Threads and loops

Is anyone aware of any issues running a loop inside a thread? I have
a thread running and inside of it I do a foreach on each row of a
datagrid and then i send an event back to the form to insert a row in
a text box. For each row on the datagrid, I add a line to the text
box... textbox += data.

The problem is my thread and the loop seem to have a problem where the
textbox has a good line or two and then every line after it is the
same. If I place a Sleep within the loop (ie. sleep(25)) then it
works fine.

Anyone encounter something weird like this?

That sounds like you're accessing the UI from a worker thread. You
mustn't do this.

Hi, yeah I am utilizing a brThread business rule class that handles
the threading and am using invoke... however, I will check to see if
it is a worker thread which could be the problem.... just seems like
my thread is out of control and debugging doesn't really help me.
Again, adding a sleep in there fixes it, but is not really a
solution. Thanks!
