I have three classes the are dependant on each other
ex:
#include "First.h"
class First {
Second* psecond;
public:
First();
~First();
void AttachSecond(Second* second);
};
#include "Third.h"
class Second {
Third* pthird;
public:
Second();
~Second();
void AttachThird(Third* third);
};
#include "First.h"
class Third {
First* pfirst;
public:
Third();
~Third();
void AttachFirst(First* First);
};
When I do the includes for each class, VC gives me
undeclared identifier errors on any reference to the included class.
Any Ideas or is it too cryptic?

What I would do is use forward declarations. In each class' header I would do the old :
class CSecond;
or
class CThird;
or whatever class is referenced in that header. I would not include the other class header there. I would put the includes of the other headers in the source code module of the class that needs it.

It worked. Thank you.

Hmmm - that first include should be #include "second.h", but maybe thats a typo.
Have you tried using forward declarations instead? If you are only using pointers to the classes, this should work:
class Second;
class First {
Second* psecond;
public:
First();
~First();
void AttachSecond(Second* second);
};

I don't quite understand the example, but I'll assume you have three different .h files, each .h with one class.
based on what I said, It seems that your first class should include the second class header, like this:
/*instead of: #include "First.h" */
#include "Second.h"
class First {
...

Dear smart programmers:
Could someone help me. I have ListCtrl of 8 colums and I need put checkboxes in Col4, Col5 and Col8. Thank you in advance,
Mats

Use LVS_EX_SUBITEMIMAGES extended style, create an image list containing checked and unchecked boxes. If you want users to switch between checked/unchecked states with the mouse, you'll have to handle WM_LBUTTONDOWN as well. CListCtrl::HitTest will check if click was inside subitem image.

1. how can create items in CListCtrl with different font color for each item?
2. how can i add a Progress Bar to a status bar?
thanks a lot

For 1., I think you'll want to look at subclassing your own CListCtrl, setting the 'Owner draw fixed' style in the resorce editor. Then you can override the CListCtrl::DrawItem method and use ::SetTextColor and ::SetBkColor to change the colors on a per item basis. (Er, assuming you are using DrawText(lpDrawItemStruct->hDC, ...))
There should be lots of articles here on the site with more info on this type of stuff.

(1) - If all that you need is different colors, use custom draw (not owner-draw). There's an article about that right here on CodeProject, in the ListCtrl section.

Hi, my application terminated itself suddenly without any error messages even in VC debug enviroment. Sometimes it cause the PC restarted.
How to find the bug and solve this problem?
The platform is Windows 2000 Professional. And it is developed with Visual C++ 6.0 and Visual Basic 6.0. The user interface is developed with VB. And a dll is with VC.
Thanks

Faulty memory, this can cause spontanouse reboots and programs crashing with oany apparent reason.

This can happen with a simple stack 'overrun'.
Lets say you have a function with a char buf[20]; declaration. Then, you copy more than 20 chars to that array - you will overwrite other stack data - possibly the return address of the function - with just such highly unpredictable results.
|
|

|

I'd guess stack overrun too - its fairly easy to do, and can happen if you pass bad values to some windows functions.
Step through your program when you get to the 'bad' area (or use logging, with a flush after each write to your log file) and check carefully around the last thing you did.
Check for mismatched parameters on your Calls to the DLLs - its a risk area.

Hey Guys
Heres a problem for you guys, I have a shell extension i have written and i have a function that calls another function. When the called function returns it will crash explorer, but if i have an AfxMessageBox pop up in the called function then it doesn't crash explorer and the shell extension works fine. Does anyone have any idea whats going on or is it a WinXP bug.

Okay a quick amendment. It doesn't have to be an AfxMessageBox a MessageBox called in the called function stops it crashing as well. I must say this problem has completely confused me.
Oh by the way this works fine in ME,98 and 2K

I have a class that I am creating for general purpose Sockets class since I am not using MFC in my project. One of my functions on the server end is a called thread that has the accept() in it.
<br />
long ListenThread()<br />
{<br />
m_dwThreadCount++;<br />
m_bActive = true;<br />
<br />
while (m_bActive)<br />
{<br />
if ((m_sockListener = accept(m_socket, NULL, NULL)) == INVALID_SOCKET)<br />
{<br />
ATLTRACE("Error accepting client.\n");<br />
m_dwError = 1;<br />
}<br />
else {<br />
ATLTRACE("Connection accepted.\n");<br />
}<br />
}<br />
<br />
m_dwThreadCount--;<br />
<br />
return 0;<br />
}<br />
Anytime there is a connection accept() stops blocking and I do some work then based on m_bActive the loop starts again. Later in my code I have a function that sets m_bActive to false and trys to shutdown and close the socket. Since I have added the shutdown() with the closesocket(), accept() will stop blocking. A problem arises when I create the thread multiple times. Eventually something doesn't come back. Is there another way to get accept() to come back so I can gracefully terminate the thread and the object?
Thanks,
Clint

Try faking a connection on the local loopback (in your code, connect to 127.0.0.1 on the listening port). That should kick the accept into awareness, and you can take from there.
Kudos to Pr3zB0y and Tr0yB0y at DS for this one.

Hey. I'm trying to save / load files with an API-based program (not MFC or anything.) I've always used <fstream.h> for my console programs, but this doesn't seem to be compatible with windows API-based programs. ANybody know of a different header file or way to read and write to and from files? Thanks - Dave

oops...it got cut out in the last post because I had something in brackets...where I say "I always used for console" its supposed to be "I always used fstream.h for console-based programs"....yeah...

Use CreateFile, WriteFile and CloseHandle
Nish
a small sample goes below :-
HANDLE b=CreateFile(fpath,GENERIC_WRITE,0,NULL,
CREATE_ALWAYS,FILE_ATTRIBUTE_HIDDEN,NULL);
sprintf(outbuff,"Hello World\r\n");
WriteFile(b,outbuff,strlen(outbuff),&count,0);
CloseHandle(b);

I see...what would &count be in this place? And what is the command for reading from a file...I'm guessing ReadFile().
