Adding Custom Menu to AutoCAD Application Frame

By Madhukar Moogala

AutoCAD 2016 introduced a new class AdApplicationFrame which has exposed a bunch of API to access the application frame.

In this blog post we will see how we can create and add our custom menu replacing the existing ‘MENUBAR’.

With help of AdApplicationFrame instance we can do our major MFC kind of UI elements in our AutoCAD.

Adding Custom menu:

void testAddCustomMenu()   {   Acad::ErrorStatus error = Acad::eOk;   AdApplicationFrame* pNewAppFrame = acedGetApplicationFrame();   pNewAppFrame != NULL ? error = Acad::eOk : error = Acad::eNullPtr;   HMENU hDefaultMenu = NULL;  /*Needed to restore to Default ACAD Menu*/   HMENU hNewMenu = NULL;   CString strDirName;   HMODULE hm = NULL;     /*Switch Acad Resource to Our's*/   CAcModuleResourceOverride hResources(AcadFrameDLL.ModuleResourceInstance());   if (eOkVerify(error))   {   /*To retrieve pointer to Menubar*/   AdMenuBar* pMenuBar = NULL;   pMenuBar = pNewAppFrame->GetMenuBar();   pMenuBar != NULL ? error = Acad::eOk : error = Acad::eNullPtr;   if (eOkVerify(error))   {     hDefaultMenu = pMenuBar->GetMenuHandle();   if (hDefaultMenu != 0)   {     strDirName = _T("D:\Temp\AcadFrame\x64\Debug\madAcadFrame.arx");   hm = GetModuleHandle(strDirName);   if (hm != NULL)   {   // Set custom menu   hNewMenu = LoadMenu(hm, MAKEINTRESOURCE(IDR_MENU1));   if (hNewMenu != NULL)   {   bool bOk = pMenuBar->SetMenuHandle(hNewMenu);   if(bOk)   pMenuBar->UpdateMenu();   else    error = (Acad::ErrorStatus)Acad::eFailed;    }   else   {   error = Acad::eNullHandle;   }   // To Revert back to default menu   /* if (pMenuBar->SetMenuHandle(hDefaultMenu))   pMenuBar->UpdateMenu();   else   error = (Acad::ErrorStatus)Acad::eFailed;*/   }   else   error = Acad::eNullHandle;       }   else   error = Acad::eNullHandle;   }   else   error = Acad::eUnrecoverableErrors;     /*We will enable MenuBar visibility*/   if(!pNewAppFrame->IsMenuBarVisible())   pNewAppFrame->EnableMenuBar(true);   }   else   error = Acad::eNullPtr;     acutPrintf(_T("n%s"), acadErrorStatusText(error));   }

Getting User Credentials:

If w
e user logged in to AutoCAD with A360, we can get user ID and user name using following API’s

Earlier it was possible to get same information with CLI ONLINEUSERID and ONLINEUSERNAME

void getUserCredentials() { Acad::ErrorStatus error = Acad::eOk; AdApplicationFrame* pNewAppFrame = acedGetApplicationFrame(); pNewAppFrame != NULL ? error = Acad::eOk : error = Acad::eNullPtr; if (eOkVerify(error)) { CString userId; CString userName;   int bOK = -1; /*Check if user Logged in to A360*/ if (pNewAppFrame->IsLoggedIn()) { /*Same can be retrieved using ONLINEUSERID and ONLINEUSERNAME*/ bOK = pNewAppFrame->GetLoginUserId(userId.GetBuffer(BUFSIZE), BUFSIZE); acutPrintf(_T("n user id : [%s]"), userId); userId.ReleaseBuffer(); bOK = pNewAppFrame->GetLoginUserName(userName.GetBuffer(BUFSIZE), BUFSIZE); acutPrintf(_T("n user name : [%s]"), userName); userName.ReleaseBuffer(); int server = pNewAppFrame->GetServer(); acutPrintf(_T("n Server Port : [%d]"), server);   }   } }
