copied! <p>For a while now i have been using this code: </p> <pre class="lang-vb prettyprint-override"><code>Private Sub Button2_Click(sender As Object, e As EventArgs) Handles Button2.Click Dim t2 As New Threading.Thread(AddressOf SetLabelText2) t2.IsBackground = True t2.Start() End Sub Delegate Sub UpdateDelegate() Private Sub SetLabelText2() If InvokeRequired Then Invoke(New UpdateDelegate(AddressOf SetLabelText2)) Else For i = 1 To 110 Label2.Text = Text Threading.Thread.Sleep(200) Next End If End Sub </code></pre> <p>This code runs fine, except its not Multithreading my Application and puts it into a Unresponsive State.</p> <p>My Question is simple, 1.How can i fix this ( The application I will be using will have SEVERAL Function calls within </p> <pre class="lang-vb prettyprint-override"><code>If InvokeRequired Then Invoke(New UpdateDelegate(AddressOf SetLabelText2)) Else FunctionCall1() FunctionCall2() FunctionCall3() End If </code></pre> <p>they all work and take ahold of my UI Thread.</p> <p>I have been searching for quite some time now, any help is appreciated.</p> <p>-Edit- Also having issues while in a thread to read information from a form ... :) thanks for the help so far</p> <p>EDIT --- </p> <p>Ok, i have change my Code around to look like </p> <pre class="lang-vb prettyprint-override"><code>Delegate Sub setForm1PrgBarPerformStepdelegate(s As Integer) Private Sub setForm1PrgBarPerformStep(ByVal s As Integer) If Form1.ProgressBar1.InvokeRequired Then Dim d As New setForm1lblAlltextdelegate(AddressOf setForm1PrgBarPerformStep) Form1.Invoke(d, New Object() {s}) Else If s = 1 Then Form1.ProgressBar1.PerformStep() Else End If End If End Sub </code></pre> <p>This piece of code is being called with setForm1PrgBarPerformStep(1) ' or 0 </p> <p>Wich is called by my thread, ( It works ( the threading part - witch is awesome btw ), with the minor flaw of NOT doing the Perform Step - or any other UI changes I Code in the Private Sub setForm1PrgBarPerformStep() </p> <p>Is there a good reason for this?</p>
