Hello, the codegurus around the world.;)
Accroding as Network Programming for Microsoft Windows, P548,
The NETSTAT.EXE utility displays the TCP connection table, the UDP listener
table, and the IPv4 ptorocol statistics on your computer. The function used
to retrieve this information work with Windows NT 4.0 (SP 4 and later),
Windows 98, and Windows Me.
So, check the following functions.
DWORD GetTcpTable (
PMIB_TCPTABLE pTcpTable,
PDWORD pdwSize,
BOOL bOrder
);
typedef struct _MIB_TCPTABLE
{
DWORD dwNumEntries;
MIB_TCPROW table[ANY_SIZE];
} MIB_TCPTABLE, *PMIB_TCPTABLE;
typedef struct _MIB_TCPROW
{
DWORD dwState;
DWORD dwLocalAddr;
DWORD dwLocalPort;
DWORD dwRemoteAddr;
DWORD dwRemoteProt;
} MIB_TCPROW, *PMIB_TCPROW;
DWORD GetUdpTable (...), typedef struct _MIB_UDPTALBE,
typedef stuct _MIB_UDPROW, DWORD GetIpStatistics(...)
typedef struct _MIB_IPSTATS...

How do you determine where a safe break point is?
When I placed a break point at this line of code, my computer had a brain cramp and I had to reboot.
void CTPclassDlg::OnAdd()
{
CString sTmp; // break point on this line
// other code here ...
}
can someone explain?
Thanks

Taking a guess, something higher up in the call tree has corrupted the stack. If you had to reboot, does this mean you're developing on Windows 98/ME? When debugging under Windows 2000/XP, you usually don't have to reboot just because of an application error like this.

Hi Gary,
Yes I am using ME.
If I move the break point down a couple lines to where I declare an int, the debug works fine. I was wondering if it had something to do with the CString. But then again, the program execution should stop befor the line is executed.
Simply moving the breakpoint would have nothing to do with corrupting the stack. Right ?? ??

Hmmm. When I have odd behavior like this with the debugger, I usually try and do a 'rebuild all'. If the source code and the object code are out of sync, the line you think you've placed the breakpoint on in the source does not necessarily match the place in the object code where the breakpoint instruction is inserted. This can cause all sorts of unusual behavior.

Sometimes even this doesn't work. I've just had a really bizarre one where stepping over 'xor ecx, ecx' in the disassembly of 'char u[10] = "1";' caused an access violation. Access Violation on a register????? Maybe I'm missing something but that's not supposed to happen as far as I know. I ended up having to re-create the .dsw from scratch. Dropping the same source in and setting the same proj options (as far as I know) made it work just fine.
Strange but true.

b4.isqrt(u).ru/16

Just found out what *my* problem was. I had a watch set on one of my vars: 'what.size()'. Removing this makes everything work just fine. Maybe a bug in the VC6 debugger(?) Something for you to try anyway....

Well, since this is probably the simplest sort algorithm, you should be able to figure it out. Otherwise, look here[^]

If you're in a war, instead of throwing a hand grenade at the enemy, throw one of those small pumpkins. Maybe it'll make everyone think how stupid war is, and while they are thinking, you can throw a real grenade at them.

There is a probelm regarding the compaction of database. I have a database in ms-access on which i have performed some operations programatically. But When i try to compact the database using the compact database utility It is giving me errors such as "Record(s) can't be read; no read permission on <name>" error 3112 . Can anyone suggest some solution for it. I will be grateful .

Hi,
I would like to know what happens exactly when you post a form in internet explorer. I mean, i know that internet connects to a server to retrieve webpage data and to send other data but i'd like to know what it does when you post a form. Does it make another connection? How is the data of a form sent, is this a protocol? If anyone knows a place where i might learn this, please let me know. 
(the purpose is so my application can send submit forms through a direct tcp connection instead of having to insert an IE active-x control or something)
Thanks

You've got here the complete reference for the HTTP protocol, including the POST command.
In short, when you send form data, the body of your request contains pairs of value. Example, you have a login form with two edit boxes : login + password.
When the user clicks submit, IE sends something like this :
POST http:
Connection: Keep-alive<eol>
Size: 30<eol>
<eol>
login=maunder&password=grumplf<eol>
And I swallow a small raisin.

How am I suppose to declare CArray in my CDoc header file?
I've try doing like this
CArray < CPoint, CPoint > m_ptArray;
but it didn't work. The example in MSDN (COLLECT) also declare it like this. Anyone knows what 's happening?. Thanks

Saying it didn't work it not enough when you request technical help. Did compiler complain? Did program crash? Try providing better diagnostic.
And of course, make sure you include MFC collection classes header (I think it's afxcoll.h).

You did
#include <afxtempl.h>
?
|
|
|
|

I've tried to include both
#include <afxcoll.h>
#include <afxtempl.h>
in the stdafx.h but still it didn't work. The error message was
error C2143: syntax error : missing ';' before '<'
error C2501: 'CArray' : missing storage-class or type specifiers
error C2059: syntax error : '<'
error C2238: unexpected token(s) preceding ';'
Thanks. Anyone with any idea??

I still believe there's something wrong around these headers, but since you have a sample that works (from MSDN), why don't you compare line by line stdafx.h in both projects. Programming is determenistic activity, so you should be able to find what's different.

CArray is crap. Use vector.
I presume someone else has told you how to fix it, the problem is I suspect to do with how you need to decare it, with the second parameter. But the core problem is, as I said, that CArray is garbage and should not be used.

How can I code the interface like VS .net, like a docking dialogs with tabpages (solution explorer, class explorer, property dialog), and the editor tab window. Any sample like this I can find out ??

There are a lot of stuff like this, but for .Net programmers.
I like the Magic Library written in C#: http://www.dotnetmagic.com[^]

any stuff in VC++ ? as i've to use some C++ classes within it which they are not managed, and extensively use pointers. It's not convenient to use C# in this senario.
or can C# use unmanaged C++ classes with pointers ?
