Oleg, please could you help me. I have a task to emulate a call of menu item (in dynamic menu) in third-party application which uses codejock toolkit. I’m a newbie at C++ but here is my plan. With help of Spy++ I found out that I can SendMessage to the main window with WM_COMMAND and wID. And it works! But at the moment I can’t get a wID (for testing I used wID from Spy). So then I used EnumChildWindows for getting all controls and tried to get menu handle with GetMenu…
Remarks from MSDN: GetMenu does not work on floating menu bars. Floating menu bars are custom controls that mimic standard menus; they are not menus. To get the handle on a floating menu bar, use the Active Accessibility APIs. and AccessibleObjectFromWindow. But every time I’ve received null. Is there another way to do that? |

HI,
Its not that easy :( our Menus have no HMENU handles. But indeed can try Accessibility feature that we support. You have call AccessibleObjectFromWindow for Menu window - see it in Spy++ - its window with XTPToolBar class. ------------- Oleg, Support Team CODEJOCK SOFTWARE SOLUTIONS |

BOOL CALLBACK // callback for EnumChildWindows
EnumChildProc(HWND hwnd, LPARAM lParam) { IDispatch** ppMenu; AccessibleObjectFromWindow(hwnd, OBJID_NATIVEOM, IID_IDispatch, (void**) ppMenu); // ppMenu is always null (even when hwnd=000103BE) return TRUE; } Here is code I use to get menu. As you see AccessibleObjectFromWindow is called for every child in window. I tried to insert OBJID_MENU instead of OBJID_NATIVEOM like dwObjectID parameter and IID_IAccessible instead of IID_IDispatch, but result is “te je yaica, vid sboku”. 
Window with handle 000103B0 is main window. Window with handle 000103BE is my menu I need to get access. |

Hi,
I see it has class name "Afx:004..." it means it _very_ old version that didn't support accesibility :-( ------------- Oleg, Support Team CODEJOCK SOFTWARE SOLUTIONS |

Hi,
One of our client application is using Xtreme command bars. Its version is 8.7.0.0 . Is there any method to know the menu item status (Disable/Enable) programmatically from another application
