Hi,
I Have a Windows Form to which I linked classes that generates reports using crystal report.
I want thoses classes to be independant of the Form but I want the Form to display the progress bar to show the progress of the class in creating the Report.
I though of 2 ways to do this,
#1- Make the class set a public value for the progress of the creation of the report and make a thread in the Form that would go and request the process of the class every X seconds.
#2- Create events in my class and handle them with the Form to display the proper progress of the class.
I went for the option #2, I though it was easier that way, creating threads for a progress bar seemed too much work for what it would of done.
So I have something that looks like this
When I put the GetEvent function inside the clsCrystalReport class, the event is caught, but when it's in the class that instanciate the class, it doesn't.
How can I solve this problem to be able to display a progress bar in an interface that is independant of the class it creates ?
