Question

I have few controls on my MainForm in Winforms application. For example control that updates progress of each operation. These operations are classes which in run in different Thread.

How can i properly update those controls ?

Answer 1

in your main form you can add a function like this one

private delegate void doSomethingWithTheControlsDelegate(object obj);

public void doSomethingWithTheControls(object obj) {
 if (this.InvokeRequired) {
   this.BeginInvoke(new doSomethingWithTheControlsDelegate(this.doSomethingWithTheControls), obj);
 } else {
   // do something
 }
}
