The following code example creates a MenuCommand object, configures its properties, and adds it to the IMenuCommandService.
Create an instance of the Component1 class on your form and open the form in a design environment like Visual Studio. Press the F1 key to invoke the MenuCommand.
#using <system.dll> #using <system.design.dll> #using <system.windows.forms.dll> using namespace System; using namespace System::ComponentModel; using namespace System::ComponentModel::Design; using namespace System::Security::Permissions; namespace CppMenuCommand { public ref class CDesigner: public ComponentDesigner { public: [PermissionSetAttribute(SecurityAction::Demand, Name="FullTrust")] virtual void Initialize( IComponent^ comp ) override { ComponentDesigner::Initialize( comp ); IMenuCommandService^ mcs = static_cast<IMenuCommandService^>(comp->Site->GetService( IMenuCommandService::typeid )); MenuCommand^ mc = gcnew MenuCommand( gcnew EventHandler( this, &CDesigner::OnF1Help ),StandardCommands::F1Help ); mc->Enabled = true; mc->Visible = true; mc->Supported = true; mcs->AddCommand( mc ); System::Windows::Forms::MessageBox::Show( "Initialize() has been invoked." ); } private: void OnF1Help( Object^ /*sender*/, EventArgs^ /*e*/ ) { System::Windows::Forms::MessageBox::Show( "F1Help has been invoked." ); } }; }
