Joining Threads in VB.net
By: Steven Holzner in VB.net Tutorials on 2010-10-23
You can use the Join method to wait until a thread finishes; this method will return when the thread is finished executing. Here are the various forms of this method:
-
Sub Join- Waits for a thread to die.
-
Function Join(TimeOut As Integer) As Boolean -Waits for the thread to die or for a specific timeout, given as a number of milliseconds, to elapse. Returns True if the thread died, False if the call timed out.
-
Function Join(TimeOut As TimeSpan) As Boolean- Waits for the thread to die or for a specific timeout, given as a TimeSpan object, to elapse. Returns True if the thread died, False if the call timed out.
Example:
Private Sub Button1_Click(ByVal sender As System.Object, _
ByVal e As System.EventArgs) Handles Button1.Click
Thread1.Start()
Thread2.Start()
Thread1.Join()
Thread2.Join()
TextBox1.Text = c.Total
End Sub
