ALL? That's a really bad idea...
Your question could mean two different things.
a/ I just want to change the tooltip when a user hovers the mouse over my icon.
b/ Something has happened, and I want to tell the user about it, by popping up the tooltip right now. Like plugging in a network cable, etc.
(a) is easy, (b) isn't hard - but it took a bit of digging.
To create the notification icon, you'll need to fill in a NOTIFYICONDATA structure. I keep a copy of it as a member variable.
m_Nid.cbSize = sizeof (NOTIFYICONDATA);
m_Nid.hWnd = GetSafeHwnd ();
m_Nid.uFlags = NIF_ICON|NIF_MESSAGE|NIF_TIP;
m_Nid.hIcon = m_hTrayIcon;
lstrcpy (m_Nid.szTip, _T("Iain's IP changer"));
Shell_NotifyIcon (NIM_ADD, (NOTIFYICONDATA *)&m_Nid);
To change the tooltip, you can use NIM_MODIFY:
m_Nid.uFlags = NIF_TIP;
lstrcpy (m_Nid.szTip, _T("New message"));
Shell_NotifyIcon (NIM_MODIFY, (NOTIFYICONDATA *)&m_Nid);
And to make balloon tip box...
m_Nid.uFlags = NIF_INFO;
m_Nid.uTimeout = 4000;
m_Nid.dwInfoFlags = NIIF_INFO;
lstrcpy(m_Nid.szInfo, _T("Some text"));
lstrcpy(m_Nid.szInfoTitle, _T("A Title"));
Shell_NotifyIcon (NIM_MODIFY, (NOTIFYICONDATA *)&m_Nid);
This is code trimmed from a working application. I *may* have missed something out, in which case reading up on NOTIFYICONDATA will help you a lot. Also, the balloon tooltip will only work with later shell versions.
Good luck,
Iain.

Hello everyone,
Just confused about DLL function by ordinal concept. Ordinal should be on the other part of by name.
But to use DLL function by ordinal technique, we need,
1. Write a .DEF file and write down function ordinal (index);
2. Use LoadLibrary and GerProcAddress to get the function pointer than use the function.
In (2), we still need to use function name as input parameter to GetProcAddress. So, my question is, DLL function by ordinal technique is not pure by ordinal, still need function name information?
thanks in advance,
George

MSDN on GetProcAddress [^]
lpProcName
[in] Pointer to a null-terminated string that specifies the function or variable name, or the function's ordinal value. If this parameter is an ordinal value, it must be in the low-order word; the high-order word must be zero.

Thanks CPallini,
My mistake before. I use .DEF file but still use by name approach.

You actually do need this method if you have a nice C++ "beautified" function name DLL so it can't still rely on function name since ... well, that may change (not fun to stumble on this by yourself, trying to load what you know function name is and then going  when watching the insides). As for method, previous reply says it all.

Thanks Dexterus,
I do not 100% understand the situation you mentioned.
"if you have a nice C++ "beautified" function name DLL so it can't still rely on function name since", could you give us more description or some pseudo code please?
regards,
George

Hello everyone,
Just to confirm what is the most correct way beyond a just working function.
1.
We need to add extern "C" to both variable/function definition/declaration? Or only need to add to the variable/function declaration?
2.
How about extern? Declaration only or both declaration and definition are required?
BTW: previously, I only add to declaration, but after reading more and more code which add to both declaration and definition, I come to here to ask this question.
thanks in advance,
George

We need to write a server side script to answer all questions posted by George_George. Basically the script would do it by Googling and returning the first 5 links back.

The above holds true for most peaple posts. 
On the other hand, some George_George ones are indeed deep & tricky (though ofter matter academic interest) and Google is of little help about.

Thanks CPallini,
1.
I have read the link, for normal function, extern "C" only need to be added to declaration, and if containing function pointer as parameter, we need to add extern "C" to definition as well.
2.
But the link only covers functions, my question is about variables, does the same rule applies to variable we well?
3.
How about your points to my question (2)?
regards,
George

The link shows that the general behaviour, i.e. use extern "C" only on declarations, may have pitfalls. That's all.
IMHO if you use extern "C" both in declarations and in definitions then you're safe.

I need to provide http download resume support in my application. Similar to resume support present in most of download mangers.
Kindly point me to some example code or how should I go about this problem.

Of course resume depends to that web site that support of it or no.

That is not a problem as most of Download manger works for most but some site. That is acceptable. But how can I support download resume in VC++ for the sites which provide resume support.

Hi all,
i am writing a dll on VC6.0 which internally executes a command over command prompt using system() API. while executing the command, command prompt is being displayed on the screen.i don want this command prompt to be displayed on the screen.Is there any method which supress the command prompt from being displayed on the screen,or is there any other API which does as system() API without displaying commandprompt..?
Thanks in advance

Look up the ShellExecute() function.
