visual c: I am having trouble adding a control to ControlCollection in a class I have derived from GroupBox. Here is what I've got

__gc class RowColumn : public System::Windows::Forms::GroupBo

public
RowColumn()
ignoredcontrols = new System::Windows::Forms::Control::ControlCollection(this)


void IgnoreControl(System::Windows::Forms::Control* control)
ignoredcontrols->Add(control)


void DoSomething()
int i
for(i=0; i < ignoredcontrols->Count; i++)
/*...*



private

System::Windows::Forms::Control::ControlCollection* ignoredcontrols
}
