Getting an error after using ActiveForm in debug mode!!!

edua_11368

Hello, After using method activeform to get the active form in my app, i try to clear all controls from the form so i can add new controls to it, just like this: Form currentForm = Form1.ActiveForm; currentForm.Controls.Clear(); When i run in debug mode, i get an exception for Object reference not set to an instance of an object. But if i run it without debbuging it works ok. Does anybody know why this happens? Thank you. e.

Thank you for responding Ytram, Actually I need to instantiate a new form because I am changing it from a class other than where the form is.

Have you tried just doing this: this.Controls.Clear(); Overall though, I dont' know why you're getting that exception. I just did it in an application real quick and it worked either way. But try it without instantiating a new form, as that's not necessary anyways.
