The format string given to printf() implicitly says how many parameters should be there. For your average() method, there is no way the method can tell how many parameters are there, so the terminator is required.
Hope this helps,

It probably uses vsprintf I
f there is a format specifier. e.g. printf("%d %d", 42, 53) you can easily work out the number of argumenst required, you must make the assumption they are all present though.

printf() avoids it by not caring. It assumes that you are passing the same number of args as there are option switches in the format string. If you don't, printf() might crash.
So what can you do? There are basically two choices:
- Add a count parameter to your function:
int average( int first, int count, ... )
- Do what the MSDN example does, and supply a terminator value.
p.s. Thank you for taking the effort to format your question.

I declared a CFont object and a CIpAddressCtrl object in the header of CWnd-based class
CFont m_Font;
CIpAddressCtrl m_IpAddress;
In the Create method of this class I created font and set it to the CIpAddressCtrl object.
m_Font.CreateFont(...);
m_IpAddress.SetFont(&m_Font);
After destroy my class Numega's BoundsChecker tell me about Invalid Argument: DeleteObject. Why?? If I use other control instead CIpAddressCtrl (tested with CComboBox and CEdit) then all OK.
Best regards,

MSDN says: "When you finish with the CFont object created by the CreateFont function, first select the font out of the device context, then delete the CFont object."
You could call m_Font.DeleteObject() in the dtor of the CWnd class.

In a case with the chosen font in CIpAddressCtrl DeleteObject results to the same error.

NetWkstaUserGetInfo shows you the current user logged in the workstation. Maybe you need to update your SDK.

Thanks for your answer, but i am using SDK Feb. 2003. The SDK documentation says, that...
The NetWkstaUserGetInfo function returns information about the currently logged-on user. This function must be called in the context of the logged-on user.
I tried to use this function in a differnt user context...

I am sorry, I wasn't very sure about your question. I really cannot be of much help but have a look at NetWkstaUserEnum. I have never used this function but I just came across it.

Hi,guys
i have got a big problem getting the currently logged on user (WinSta0\Default). There are some functions like GetUserName(Ex) and NetWkstaUserGetInfo, but they show only the user of the current process. My problem is, that i am using a service running under local Admin and want to know who or if somebody is logged on.
Thank you very much

OK, this is really bugging me  . Why doesn't the vector class have a remove(int) method? Why does it insist on doing everything with these damn "iterators"? No wonder I hate STL!!
[/rant]
What is the best way to remove an element by index from the middle of a vector? At the moment I'm doing this:
int nElementToRemove = 5;
vector<type>::iterator it = myvector.begin();
while(nElementToRemove--)
it++;
myvector.erase(it);But surely there must be a better way. Does anyone know of the best way to do this?
