Error: can not be called in the list of arguments c ++

I've been trying to use the bunifu transition in windows form c ++, but without secesso because of the error. In c # would be "bunifutransition.showsync (panel);" but in c ++ neither a c # converter for c ++ solves.

C #

Private: System::Void bunifuImenu_Click(System::Object^ sender, System::EventArgs^ e){
     bunifutransition.HideSync(panel3);
     bunifutransition.ShowSync(panel4);
}

C ++ ERROR

Private: System::Void bunifuImenu_Click(System::Object^ sender, System::EventArgs^ e){
     bunifutransition->HideSync(panel3);
     bunifutransition->ShowSync(panel4);
}
