I’m passing a reference of a form to a class. Within this class I believed I could use formRef->Controls['controlName'] to access properties on the control.

This works for a few labels, but on a button I receive a ‘Object reference not set to an instance of an object.’ when I try to change the Text property.

Help or explanation appreciated…

  1. I did this, and it’s working. Could possibly be safer as I can check if the control actually exists…

    array<Control^>^ id = myForm->Controls->Find('myButton', true); id[0]->Text = 'new text';

    I think the reason it breaks is that the button is on another panel. I didn’t think of that when I posted. The new solution will search all children too, so it’s an improvement.
