Use BackgroundWorker with any class
BackgroundWorker works only with the classes that implements interface ISynchronizeInvoke – in order to use BackgroundWorker with any class necessary to make the following changes in the code.
The code after the changes ( BackgroundWorker.cs ):
private void InvokeDelegate(Delegate del, params object[] args)
{
ISynchronizeInvoke synchronizer = del.Target as ISynchronizeInvoke;
try
{
if(synchronizer != null) //A Windows Forms object
{
if (synchronizer.InvokeRequired == false)
{
del.DynamicInvoke(args);
return;
}
synchronizer.Invoke(del, args);
}
else //Not a Windows Forms object
{
del.DynamicInvoke(args);
}
}
catch (Exception e)
{
Trace.WriteLine(e.Message);
}
}
Thanks to Roy Osherove for help in the solution of this problem
