Hi,
am playing around with workerthreads in vb.net 2003
I made a small project for testing that i uploaded
in my solution i got 2 projects; 1 for a form and 1 for threadlogic(businessclass if you will)
i was wondering if anyone could tell me if this way of updating the controls is 'allowed' because i'm reading everywhere you're not allowed to set a control in a thread (one which didn't create the controle). Although it seems to work.
The reason im asking is because the helpfile on ISynchronizeInvoke.Invoke it clearly says;
First parameter = A Delegate that contains a method to call, in the context of the thread for the control
Also in the OnComplete-methode i'm having trouble;
Dim dhw works i can't seem to declare the type (invalid cast) because the delegate is in the form-project (i tried copying it into the class but doesn't work, setting a reference to a form-project is not allowed). Anyway around this??
Further i wanted to ask if a reference to system......forms is common in a project that handles threads.
tnx in advance,
Jannick
ps: i just saw/tested my attachment and forgot to mention; open project testingthread and delete the 2 components that arent found ( clsTest and frmMain)
