I tried that and am seeing crashes - if not on the first call, then on the second. The call to CXTPShortcutManager::CompareAccelKey appears to being doing what is expected of it. However, a few lines after it returns to CXTPCommandBar::OnKeyboardTipChar I get the crash in the call to OnKeyboardTip. At that point, pTip->m_pOwner usually points to freed memory (0xfeeefeee).

The stack is

  CObject::IsKindOf(0x070e17d4) C++
  AfxDynamicDownCast(0x070e17d4, 0x20fc7728) C++
  CXTPCommandBar::OnKeyboardTip(0x20fc5c78) C++
  CXTPCommandBar::OnKeyboardTipChar(0x00000062) C++
  CXTPCommandBar::OnHookKeyDown(0x00000062, 0x00500001) C++
  CXTPPopupBar::OnHookKeyDown(0x00000062, 0x00500001) C++
  CXTPCommandBar::OnHookMessage(0x00000000, 0x00000100, 0x00000062, 0x00500001, 0x00000000) C++
  CXTPKeyboardManager::ProcessKeyboardHooks(0x00000100, 0x00000062, 0x00500001) C++
  CXTPKeyboardManager::KeyboardProc(0x00000000, 0x00000062, 0x00500001) C++

I've tried debugging it to see how pOwner is going bad, but with breakpoints in place, the crash goes away. I tried making the breakpoints conditional on the owner data looking wacky [eg (*((*pTip).m_pOwner)).m_dwRef < 0 || (*((*pTip).m_pOwner)).m_dwRef > 100]. Sometimes they fire, but other times I crash without the breakpoints firing. In those cases the data doesn't look freed, but since I'm crashing something must be bad.

Any thoughts?

Hi,

try add these lines in sources:

BOOL CXTPShortcutManager::CompareAccelKey(TCHAR chAccel, UINT wParam)
{
if (wParam >= VK_NUMPAD0 && wParam <= VK_NUMPAD9)
return (UINT)chAccel == (wParam + '0' - VK_NUMPAD0);
...

Switching Windows with Keypad Numbers : In 11.2.0 and 11.2.1, I can't...

In 11.2.0 and 11.2.1, I can't switch windows in my MDI ribbon app using the numbers on the keypad. That is, create a few windows, then hit Alt-V-S-enter then 0 or 1 or 2. The numbers above the keyboard work fine. This fails in the RibbonMDISample as well. It just dings at me. However, the samples work in 11.2.2 and 12.0.

What's the difference? Was it a bug or did the sample change the way it does something? Is there anything I can do in 11.2.0 to make this work?
