I am getting a wierd error and I think it is because something may be declared wrong, I guess I am just not sure where:  Any clues?
Inside header file:
friend ostream &operator << (ostream &, ListNode &);
Inside .cpp file:
ostream &operator << (ostream &strm, ListNode& *Node)
{
while(Node != NULL)
{
...
}
return strm;
}
Errors:

 It seems like the compiler doesn't recognize the ListNode type. Make sure that you have included the header file that contains the declaration for ListNode.

This is in the same file that the implementation of the list exists.

in the line:
<br />
ostream &operator << (ostream &strm, ListNode& *Node)<br />
are sure you didn't mean to write:
<br />
ostream &operator << (ostream &strm, ListNode& Node)<br />
Just trying to help even if i'm way off =)

I'd concur that a reference to a pointer is a bit funny. What is a ListNode ? Have you tried putting class ListNode; above the operator ?

Nope, but just did....AND IT WORKED! What is the purpose of doing a forward reference here? ( please explain ) I also switched it so that it was only passing a pointer not a reference to the pointer (it's getting late  ). Thanks Christian.

Hi,
I'm trying to get the address of the windows proc of a running application using:
WNDPROC AppWndProc = (WNDPROC)GetWindowLong(m_hWnd, GWL_WNDPROC);<br />
DWORD errVal = GetLastError();
The call to GetWindowLong fails (returns null) and the value returned from GetLastError() is 5, which is an access denied result.
I'm not sure if i'm missing something, but how is it that this application is preventing me from getting this address ? Is there some way to prevent people from using GetWindowLong ? I want to subclass this app so that when a user moves it i can be notified as well.
Thanks

Are you in a separate process? If so you will need to do something else to get your DLL loaded in their process. Any address that is returned to you by this function will only be valid in the process that contains the window.
Your problem may be related to that fact, but I am not certain.

Hi,
I posted this before, but no one responded. 
I'm new to C ++/mfc and I'm trying to modify a chat program to have the capability to transfer files as well as messages.
I found help from with code to send the file from this forum, but when I implemented it, I keep getting an error, "Unknown error while accessing unnamed file".
I put a button on the client side, and when the person clicks on it, the file dialog box is supposed to open, and the person can choose the file to send.
I get the dialog box, but I get the error right after I choose the file.
I put messages throughout the code to see where the program has reached, and it seems to be going through fine! It's also reading the data!
I'm really confused!!
I'm pasting the code below. If anyone has any idea what I'm doing wrong please respond.
-------------------------------------------------
void CMainFrame::OnSFile()
{
MessageBox("File Transfer");
CSocket cSocket;
cSocket.Create();
cSocket.Connect((LPCTSTR(m_strServerIP)),m_iFTPort);
csocketfile sf(&cSocket);
CArchive ar(&sf, CArchive::store);
/*code for CFileDialog goes here*/
static char BASED_CODE szFilter[] = "All Files (*.*)|*.*||";
CString strPath;
CFileDialog m_ldFile(TRUE,".*","*.*",OFN_HIDEREADONLY | OFN_OVERWRITEPROMPT, szFilter);
// Initialize the starting directory
//m_ldFile.m_ofn.lpstrInitialDir = _T("C:\\");
// Show the file open dialog and captures the result
//if IDOK
if (m_ldFile.DoModal() == IDOK)
{
strPath = m_ldFile.GetPathName();
CFile myFile(strPath,
CFile::modeRead | CFile::typeBinary);
MessageBox("here");
//get file info
DWORD length = myFile.GetLength();
MessageBox("here2");
char *data = new char[length];
MessageBox("here3");
myFile.Read(data, length);
MessageBox("here4");
//send it across
ar << myFile.GetFileName();
ar << length;
ar.Write(data, length);
delete[] data;
myFile.Close();
}
MessageBox("here5");
}

If you're really new to C++, you need to forget MFC and Windows, and do some console programming until you've had a chance to learn the core language properly.
Do you know how to use the debugger ? Do you know what line is breaking ? Do you know if you have a connection first ?

Thank you for responding. 
I actually have to do this for an assignment in one of my MSc classes.. Networking. So, I have no choice but to dive into everything at once..
Also, I have tried putting messages in the code to see if the program is actually reaching that part of the code... and it goes through fine... then I get the error.
I'm not sure if I'm using debugger properly, but I put a break point at several places, and it went through again... then the error.
I showed this to my professor yesterday, and he said it was puzzeling as well.
You asked if I had a connection. You mean to the server right? Yes I do...
If I am sending a file, but there is no receiving code on the server side, what will happen?
I'm wondering now if it is my sending that is the problem. Maybe I'm not doing something with CArchive...
Thanks a lot for your input.

i have the process id and its name and i want to get
GUITHREADINFO object.for that purpose i have to call
GetGUIThreadInfo where i have to put idThread value .
and my question is about idthread.
inorder to get idthread i have to call GetWindowThreadProcessId where i have to put hwnd and lpdwProcessId.
is idthread of each window of a process is different ?
mey i get GUITHREADINFO object using process id and its name using some other methods ?
because when i get GUITHREADINFO object it dose not have correct thread in it.

If you're using MFC, *this will give you the HWND.

You need to make it wait. Assuming you've #included iostream and are using std::cin, it's something like
int n;
cin >> n;
This will keep accepting input until you enter something other than whitespace.

I'm sure there is an article on CP about that.

Hi
Where could I find good tutorials on making a IM client such as MSN Messenger, ICQ or Yahoo messenger?
Thanks

It's a long time, but I think that MFC comes with a client/server chat sample, that would server as a good basis for anything like this.
That's assuming you want to roll-your-own. There is code around that shows how to use the MSN protocol, so you can integrate whatever you produce with an existing service.
