RE: Re: restrictions on number of menu items in windows Explorer

Hello, Stefan.
I did hit the limit of 32 subitems in winxp+sp2.
You right, all items addes in QueryContextMenu() as:

UINT idCmd = uidFirstCmd;
HMENU hParentMenu0 = ::CreateMenu();
BOOL res= InsertMenu(hMenu, indexMenu++, MF_POPUP | MF_BYPOSITION, (UINT)hParentMenu0, _T("My tools"));
res = InsertMenu(hParentMenu0, indexMenu++, MF_STRING|MF_BYPOSITION, idCmd++, "First item");
...
return MAKE_HRESULT(SEVERITY_SUCCESS, FACILITY_NULL, idCmd - uidFirstCmd);
}

The limit number is different for different file types so I assume other programs like tortoise are cutting down available menu items. Never saw such limitation in win2k with tortoise svn control installed.

Any idea what to check for?
Thanks.

Well, the number of context menu entries *is* limited, but I doubt that if you do everything right that you would ever hit that limit. At least not on XP and later (Win2k has a lower limit).

I don't know how you coded your shell extension, but you get the number of entries you're allowed to add in the QueryContextMenu() method:
idCmdFirst and idCmdLast set the limits for you.
