Apart from the book, a good source is MSDN.
Also, Google can be a great help.

i want to handle the situation when someone logs in to the system. how do i do so?
i know WM_ENDSESSION message is sent when the user logs out. but wat is the message when the user logs in....
|
|
|
|

Short of making your own msgina.dll, I know of no such message. Applications typically don't need to be notified when someone logs in, mainly because they probably aren't running. Services, however, might since they are running regardless of whether someone is logged in or not.

I am using a standard algorithm coded from Visual C++.net
The heart of it is a formula I need to modifyfrom time to time.
As I need flexibility regarding this core formula, I would like to write it in an Excel cell, take the string via VBA and transfer it the heart of my C++ code in order modify calculation inside my algorithm.
It looks like an "uninteresting question" but solving that one could much simplify my daily life...
(How ) Is it possible to do that ?

Well you could expose a COM interface as part of your app that is consumable by VBA. That would probably be quite a load of work. Another approach would be to add interfacing with the Excel Object Model from within your app. While that would likely be much less work I cannot tell if it meets the needs of your use model.
Good luck

Yesterday (or the day before, I can't remember  )
I asked how to print a CString (with RTF codes)
Here's the basic solution.
create a 'dummy' CRichEditCtrl.
create a 'dummy' Window to contain this control.
set the RTF text in the CRichEditCtrl.
Print from there.
That's it (hope it's helpful to anybody)!
(PS: not possible to give the code, because it's to hard to strip)

Hi,
I'm new in using windows sockets.
when I try to use windows sockets in my MFC application, I get the error "Could not start WinSock.DLL, error=0x276b".
in the InitInstance method, I have initialized winsock like this:
...
WSADATA ws;
if (!AfxSocketInit(&ws))
{
return FALSE;
}
...
event if I use the WSAStartup function, I get the messagebox error.
did I forgot to initialize something? 
thanks for the help.
best regards.

I have not used AfxSocketInit but the the error it is reporting is
WSAStartup cannot function at this time because the underlying system it uses to provide network services is currently unavailable.
So WSAStartup is failing in both cases.
This is only speculation but you do have a network card in your machine don't you?

Hi,
In fact, it's a problem of linking. when I link with ws2_32.lib and mswsock.lib instead of wsock32.lib, it works fine. so it seems that wsock32.lib does not work properly?

If you look at the documentation for WSAStartup it is defined in Winsock2.h and therefore you should link with Ws2_32.lib.

Is it because you do not include link to
"Ws2_32.lib" ?

Hi,
I have exclude wsock32.lib and included ws2_32.lib in the link properties of the project and I don't get the error message.
But when I create a project that uses Visual C+ 6 with Windows Socket support (this project doesn't have any ws2_32.lib defined, it compiles and runs correctly, and when I create the same project with VS .NET 2003, I have the error I mentionned above Also a project like shareaza have no exclude libraries (like I have done)... it's maybe a problem of linking configuration.

Try not to be dependent on the wizard but do it manually instead.
The basic winsock initialization.
//initialize winsock
WSADATA wsaData;
int iRet=WSAStartup(0x101,&wsaData);
if(iRet)
return false;
SOCKET con;
con=socket(AF_INET,SOCK_STREAM,IPPROTO_TCP);
if(con==INVALID_SOCKET)
return false;
//close connection
closesocket(con);
WSACleanup();
and include ws2_32.lib in the link.

I have done manual links with ws2_32.lib and mswsock.lib instead of wsock32.lib and manual initialization and it works just fine  thanks

I play video capture and files using windowless mode in Direct Show.I'd like to show just the video images in the native video sized application window. How can I do this ? Also there is a problem first displaying the file. The captured video or files can not be shown until the main application window is dragged by mouse. How can I update the view in a Doc/view architecture ?
Sincerely

I have a small project that generates XML formatted text on a file. Simple. In my class i create an ofstream that I just stream static text but also text generated from an operation. E.g. m_OFS << "\t\t<OBJECT Name=\"" << WritePart1() << "\">" << endl;
The problem here is that the operation call is evaluated first, then the rest of the statement resulting in an output looking like this:
MyA00000Var <OBJECT Name="0012FE80">
How do get it in the correct order? Of course i can break up the statement into three parts, like:
m_OFS << "\t\t<OBJECT Name=\""; WritePart1(); m_OFS << "\">" << endl;
But I would like to stream everything in a row.
(I hope the html output will look ok)

Why not do this
std::string strWritePart = WritePart1();
m_OFS << "\t\t<object Name=\"" << strWritePart << "\">" << endl;
Assuming WritePart1 returns a string
