WPF Dispatcher {"The calling thread cannot access this object because a different thread owns it."}
- by user359446
first I need to say that I´m noob with WPF and C#.
Application: Create Mandelbrot Image (GUI)
My disptacher works perfektly this this case:
private void progressBarRefresh(){
while ((con.Progress) < 99)
{
progressBar1.Dispatcher.Invoke(DispatcherPriority.Send, new Action(delegate
{
progressBar1.Value = con.Progress;
}
));
}
}
I get the Message (Title) when tring to do this with the below code:
bmp = BitmapSource.Create(width, height, 96, 96, pf, null, rawImage, stride);
this.Dispatcher.Invoke(DispatcherPriority.Send, new Action(delegate
{
img.Source = bmp;
ViewBox.Child = img; //vllt am schluss
}
));
I will try to explain how my program works.
I created a new Thread (because GUI dont response) for the calculation of the pixels and the colors. In this Thread(Mehtod) I´m using the Dispatcher to Refresh my Image in the ViewBox after the calculations are ready.
When I´m dont put the calculation in a seperate Thread then I can refresh or build my Image.
