Re: Problem with IE style menu bar

Thanks.

Now, i changed the code to below.

The problem i met is:

(1) If i use
SetWindowLong(hMenuBarWnd,GWL_WNDPROC,(LONG)MenuBarWndProc));

to handle message in my own way, then all buttons including text on
them are invisable.

if i removed the
SetWindowLong(hMenuBarWnd,GWL_WNDPROC,(LONG)MenuBarWndProc));

then i can see the buttons and text on the toolbar

(2) though i have added BTNS_DROPDOWN style for each buttons, i can not
get TBN_DROPDOWN message at all in the producer function .


any help will be appreciated . Thanks in advance.

However, if i don't use below 2 lines codes, i can see the buttons on

if i use them, the buttons on toolbar can not be seen

Why ?????????
