GetMenuBarInfo

[jj2007]

Hi everybody,

Does qWord's GetMenuBarInfo example still work? I am on Win7-32 now, and it fails consistently with invalid parameter...

Note some assemblers complain about redefinition. Just put an if 0 ... endif around the MENUBARINFO definition on top.

Jochen,

could you attach the right source for jWasm?

The structure declaration in windows.inc is wrong.

Hi qWord,

The structure declaration in windows.inc is wrong.

thank you for the information. What's wrong?

The last two members (with "f" prefix) are bit fields:

Code Select Expand

typedef struct tagMENUBARINFO
{
    DWORD cbSize;
    RECT rcBar;          // rect of bar, popup, item
    HMENU hMenu;         // real menu handle of bar, popup
    HWND hwndMenu;       // hwnd of item submenu if one
    BOOL fBarFocused:1;  // bar, popup has the focus
    BOOL fFocused:1;     // item has the focus
} MENUBARINFO, *PMENUBARINFO, *LPMENUBARINFO;
The structure in windows.inc use two BOOLs instead of one SDWORD (BOOL).
Interestingly the  declaration that can be found on MSDN is also wrong.

The structure in windows.inc use two BOOLs instead of one SDWORD (BOOL).

In clear violation of assembly rule #1: everything is a DWORD ;-)

Thanks, it works :t
