How to change popup menu item text in runtime?

Question

I want to change popup menu item text. I have read the Modifying Smartphone menu bars in runtime article, but it does not work for me. I use the following code to change the item text.

TBBUTTONINFO tbbi; tbbi.cbSize = sizeof(tbbi); tbbi.dwMask = TBIF_TEXT; tbbi.pszText = _T("Stop"); ::SendMessage (hMenuBar, TB_SETBUTTONINFO, IDM_ACTION_ITEM, (LPARAM)&tbbi);

What am I doing wrong?

Answer

Your code is designed for changing the text of a menu bar button (not a popup menu item). Have a look at the picture to see the difference.

You can use the following steps to change text of a popup menu item:

Obtain HMENU of the corresponding popup menu.
Use standard menu API to change the popup menu.

Unfortunately, ModifyMenu API function is not supported under Windows CE. However, it is possible to emulate this function using DeleteMenu and InsertMenu.

The following code snippet changes the text of a popup menu item.

// obtain handle of the corresponding popup menu TBBUTTONINFO tbbi; tbbi.cbSize = sizeof(tbbi); tbbi.dwMask = TBIF_LPARAM; ::SendMessage (m_hMenuBar, TB_GETBUTTONINFO, IDM_OPTIONS_MENU, (LPARAM)&tbbi); HMENU hPopupMenu = (HMENU) tbbi.lParam; // emulate ModifyMenu ::DeleteMenu(hPopupMenu, 0, MF_BYPOSITION); ::InsertMenu(hPopupMenu, 0, MF_BYPOSITION, IDM_MENU_ITEM_ACTION, _T("Play"));
