TrackPopupMenuEx and WM_MENUSELECT - Visual C++ Win32

[Ryan Hehn]

Hello,

I've created a system tray icon with an asscociated popup menu. Using
TrackPopupMenuEx, my program receives a WM_MENUSELECT when a user selects an
item on the menu:

LRESULT CALLBACK WndProc (HWND hwnd, UINT message, WPARAM wParam, LPARAM
Param)
{
case WM_RBUTTONDOWN::
{
...
TrackPopupMenuEx(menu, TPM_RIGHTBUTTON|TPM_BOTTOMALIGN, pt.x, pt.y,
hwnd, NULL);
...
}
case WM_MENUSELECT:
{
UINT item = (UINT) LOWORD(wParam);
UINT flags = (UINT) HIWORD(wParam);
HMENU hmenu = (HMENU) lParam;
...

I can determine that MF_MOUSESELECT has occurred using flags, but hmenu is
NULL and item is 0.

According to the documentation, a NULL hmenu indicates the system has closed
the menu.

Does anyone have any insight as to why I'm receiving a NULL menu? Is this a
timing issue related to the system closing the menu after choosing a menu
item?

Thanks,

Ryan Hehn

Why do you need WM_MENUSELECT at all? Handle WM_COMMAND

Dear Ryan,

WM_MENUSELECT is where a cursor is over an menu item, not when the user
selects something. You should use the HANDLE_WM_COMMAND(...) command.
