Hi all:

How can I show the system menu?
(Reverse, Move, Size, Maximum, Minimum, Exit)

Thanks.

Show in what way exactly?  Do you just want it to exist in the titlebar, or
do you want to actually drop it down for the user to look at?  Please be
more specific.

Hi Remy:

Thanks for your reply.
I just want to show the system menu like a PopupMenu on Form.
Is it possible?

Thanks.

Perhaps have a look at GetSystemMenu() and TrackPopupMenu().

Hi Remy:

The System Menu can be display on my Form.
But when I click "Exit"....It will not close my Form(Exit Application).
My code is as below:

   HMENU hMenu=GetSystemMenu(Form1->Handle, FALSE);
   TrackPopupMenu(hMenu, TPM_LEFTALIGN | TPM_RETURNCMD,
      Form1->Left+10, Form1->Top+10, 0, Form1->Handle, NULL);

How can I solve this problem?

Thanks.
RaynorPao.

After playing with it a bit, it would appear that when allowing the system
menu in behavior in its native manner, it sends WM_SYSCOMMAND commands to
the form, but when using TrackPopupMenu() it sends WM_COMMAND messages
instead.  That difference is confusing the VCL as to what to do with them,
since those two messages have different implementations.

To make it work correctly, you have to take the return value of
TrackPopupMenu() (which you're already specifying the TPM_RETURNCMD flag
for, you're just not using the actual return value) and then manually send
WM_SYSCOMMAND to the form, ie:

    HMENU hMenu = GetSystemMenu(Form1->Handle, FALSE);
    int nCmd = TrackPopupMenu(hMenu, TPM_LEFTALIGN | TPM_RETURNCMD,
Form1->Left+10, Form1->Top+10, 0, Form1->Handle, NULL);
    if( nCmd )
    {
        TMessage Message;
        Message.Msg = WM_SYSCOMMAND;
        Message.WParam = nCmd;
        Message.LParam = 0;
        Form1->WndProc(Message);
    }
