Hello all
I created a AppBar under BCB 6.0

in private section of header file
        APPBARDATA abd;
================
        abd.cbSize = sizeof(abd);
        abd.hWnd = Handle;
        abd.uCallbackMessage = WM_ABNOTIFY;

        SHAppBarMessage(ABM_NEW, &abd);

        abd.uEdge=ABE_TOP;

        SetRect(&abd.rc,0,0,Screen->Width,Screen->Height);
        SHAppBarMessage(ABM_QUERYPOS,&abd);
        abd.rc.bottom=abd.rc.top+30;
        SHAppBarMessage(ABM_SETPOS,&abd);

        SetWindowPos(abd.hWnd,HWND_TOPMOST,abd.rc.left,abd.rc.top,
            abd.rc.right-abd.rc.left,abd.rc.bottom-abd.rc.top,
            SWP_NOMOVE | SWP_NOSIZE);

I placed a form in this area.
How can i implement the auto hide functionality to this form.

Look at the ABM_SETAUTOHIDEBAR appbar message.

Hello Remy

In the HIDE button i placed the code.

abd.cbSize = sizeof(abd);
abd.hWnd = frmMain->Handle;
abd.uEdge=ABE_TOP;
abd.lParam = true;

SHAppBarMessage(ABM_SETAUTOHIDEBAR, &abd)

Any wrong with this code.
The function is returning true but no output.

Thanks
SA

Are you also doing all the functions in your first message?

>The function is returning true but no output.

What "output" were you expecting?

I would also point out (this shouldn't be a problem) 
>abd.lParam = true;
that "true" is a C++ value while "TRUE" is a WinApi value.

The space occupied by appbar is not going to the screen edge, the form is 
still visible completely.

I tried by assigning TRUE but no result.

Well, you are telling it to be top-most with your setwindowpos
MS says to use MoveWindow during the startup code, and SetWinfowPos in
response to hiding/showing.
You might try changing to MoveWindow, if that doesn;t work, maybe
using HWND_BOTTOM for the inital position.

Are you processing the windows messages WM_ABNOTIFY and checking for
the sub-messages?
Also  WM_ACTIVATE   WM_WINDOWPOSCHANGED

Hello Bob Gonder thanks for the reply.

In the intial startup code i have

SetWindowPos(abd.hWnd,HWND_BOTTOM,abd.rc.left,abd.rc.top,
            abd.rc.right-abd.rc.left,abd.rc.bottom-abd.rc.top,
            SWP_NOMOVE | SWP_NOSIZE);

        MoveWindow(abd.hWnd,abd.rc.left,abd.rc.top,
                                abd.rc.right-abd.rc.left,
                                abd.rc.bottom-abd.rc.top,TRUE);

That's an awful lot of code just to set the z order.

I think you should just start over with the code shown in the link I
gave last time.
The first 2 routines show how to set it up.

The last 2 are probably for non-autohide bars, but you might add those
in as well.

Can you pls give detail about the routines or a snip of code.
Thanks

What detail do you need?
The code is commented.
The documentation for the calls and parameters are only a few clicks
away.

The code is in the link

The code used to hide the appbar.

                abd.uEdge = ABE_TOP;
                abd.lParam = TRUE;
                abd.cbSize = sizeof(abd);
                abd.hWnd = frmMain->Handle;

                SHAppBarMessage(ABM_SETAUTOHIDEBAR, &abd);

The function is returning true but appbar is still visible.
Thanks
