I used function:

BOOL InsertMenuItem( HMENU hMenu,
UINT uItem,
BOOL fByPosition,
LPCMENUITEMINFO lpmii
);

to add consecutive menu elements in QueryContextMenu() shell interface.
After adding all of them only first one i displyed. I added MF_STRING type
menues.

I checked through debugger, they all are present there in menu.
If i try adding consecutive popup menues it works fine and can add as many
as I want.
Only MF_STRING type menus wont work. Only first inserted menu item is
shown. :-(

Thanks for help, Rajko.
 
I found out what was wrong.
Interface function GetCommandString(..) needed different values for each
inserted menu item.
I case all items have the same help string only first item is displayed.

Have you returned the correct value - indicating that you've added
multiple menu items?

Thx David.
I included HRESULT(SEVERITY_SUCCESS, 0, idCmd - uidCmdFirst);
With idCmd incremented on each menuInsertItem().

That sounds like you're doing the right thing there then.

Can you show a short example that illustrates what you have - perhaps
someone can spot something.

Thx for all. Now it's working ok.
Solution was to add different CommandString for each menu item I inserted.

If anyone else have such problem here is what I did.
I have two menues(1st plain menu item and 2nd popup menu).
1st have index m_InsertedCmdIndex and 2nd = InsertedCMCmdIndex.
