Get Shell_NotifyIcon to show tray balloon tip

[wraithdu]

EDIT - fixed

I'm stumped. This *should* work. I've followed the same method that AutoIt and AHK both use internally for the TrayTip() function. I can add a new icon, and destroy it, but the balloon tip will not show even though the function returns success. I've tested on Vista and XP and neither work. Any ideas would be appreciated!

ModernMenu includes this functionality.

You've got to be kidding me, 1 f'ing struct element was wrong! MSDN said NOTHING about szTip being 128 TCHARS. Bastards....

Thanks for the nudge

MSDN

szTip

A null-terminated string that specifies the text for a standard ToolTip. It can have a maximum of 64 characters, including the terminating null character.

For Windows 2000 (Shell32.dll version 5.0 [ http://msdn.microsoft.com/en-us/library/bb776779(VS.85).aspx ] ) and later, szTip can have a maximum of 128 characters, including the terminating null character.

Ugh, I was going from the structure definition which shows just TCHAR szTip[64]. Usually they put an #ifdef in there with some windows version info or something. Live and learn.

[ProgAndy]

There is an #if ... MSDN

...
#if (NTDDI_VERSION < NTDDI_WIN2K)
    TCHAR szTip[64];
#endif
#if (NTDDI_VERSION >= NTDDI_WIN2K)
    TCHAR szTip[128];
    DWORD dwState;
...

Shit. I have a locally installed MSDN library (from VS2008), and I don't have any of that -

typedef struct _NOTIFYICONDATA {
    DWORD cbSize;
    HWND hWnd;
    UINT uID;
    UINT uFlags;
    UINT uCallbackMessage;
    HICON hIcon;
    TCHAR szTip[64];
    DWORD dwState;
    DWORD dwStateMask;
    TCHAR szInfo[256];
    union {
        UINT uTimeout;
        UINT uVersion;
    };
    TCHAR szInfoTitle[64];
    DWORD dwInfoFlags;
    GUID guidItem;
    HICON hBalloonIcon;
} NOTIFYICONDATA, *PNOTIFYICONDATA;
