Thread Questionfrom main application called MainForm. Inside ThreadMain, I call a subroutine WriteLine from the MainForm. Will WriteLine run/processed inside or outside the thread ? Thanks. Code from main appl: Public Class MainForm Private Session As ClientSession = Nothing ' Create a new instance of the ClientSession object and a worker ' thread that will handle the socket I/O Session = New ClientSession WorkerThread = New Threading.Thread(AddressOf Session.ThreadMain) ' Initialize the client session object with the reference to ' this form, and the socket that was created Session.ClientForm = Me ' Initialize the worker thread and start its execution ' WorkerThread.ApartmentState = Threading.ApartmentState.STA WorkerThread.Name = "WorkerThread" WorkerThread.Start() Public Sub WriteLine(ByVal Line As String) : Code from inside thread:end sub Public Class ClientSession Public ClientForm As MainForm = Nothing Public Sub ThreadMain() : ClientForm.WriteLine(strBuffer)Anything invoked in a Thread should run inside that thread. It's analogous to
launching a separate application.

I just want to make sure. So, even though the code for WriteLine is inside MainForm, but since it is called from ThreadMain, it will run inside the thread, right ? Thanks.

Someone else suggested to marshal the call onto the form thread, by using the Invoke, or BeginInvoke function. The following code is what I do. If I do like the following, will sub PQ be executed on the MainForm or the Class GT Thread ? Thank you. Public Class MainForm Private GSession As GT = Nothing Private GWorkerThread As Threading.Thread = Nothing Public Sub ConnectMenu_Click : ' Create a new instance of the ClientSession object and a worker' thread that will handle the socket I/O GSession = New GSession GWorkerThread = New Threading.Thread(AddressOf GSession.ThreadMain) GSession.ClientForm = Me GSession.cb = AddressOf ProcessQuote ' Initialize the worker thread and start its execution GWorkerThread.Name = "WorkerThread" GWorkerThread.Start() : Sub PQ(ByVal Packet As String, ByVal sCaller As String)end sub Inside the Class Thread: Public Class GT Public ClientForm As MainForm = Nothing Public Delegate Sub PQCallBack(ByVal Packet As String, ByVal sCaller As String) Public cb As PQCallBack Public Sub ThreadMain() Dim d As PQCallBack d = cb d(strBuffer, "CMC") Show quoteHide quote "Brian Gideon" <briangid***@yahoo.com> wrote in message news:1149523419.910250.281280@i39g2000cwa.googlegroups.com... > > fniles wrote: >> Thanks. >> I just want to make sure. >> So, even though the code for WriteLine is inside MainForm, but since it >> is >> called from ThreadMain, it will run inside the thread, right ? >> > > Yes, that is correct. > For future reference, the microsoft.public.vb.general.discussion newsgroup
