part "add to list"

AddToCommandList(tar_moni_id, tar_port_num, control, priv);
/*** add B to list B ***/
binding_ack_list *pAck = new binding_ack_list;
pAck->moni_id = moni_id;
pAck->tar_moni_id = tar_moni_id;
pAck->tar_port = tar_port_num;
pAck->done = false;
sysinfo.bindingacklist.AddTail(pAck);
part "use the list"
void CPooling::CommandControl()
{
byte data[16];
data[0] = 0xff;
data[2] = 0x34;
data[3] = 0 ;
data[8] = 0xfe;
cmd_list *pCommand;
POSITION pos1, pos2;
CString temp;
m_CS.Lock();
for (pos1 = sysinfo.cmdlist.GetHeadPosition(); (pos2 = pos1) != NULL;)
{
pCommand = sysinfo.cmdlist.GetNext(pos1);
if (pCommand->trial > 2)
{// remove
sysinfo.cmdlist.RemoveAt(pos2); //remove in list if trial > 3
delete pCommand;
}
else
{// read
data[1] = pCommand->moni_id;
data[4] = pCommand->port;
data[5] = pCommand->control;
data[6] = pCommand->priv;
data[7] = genChkSum(data, 6);
pCommand->trial++;
for (int i=0; i<9; i++)
{
p232->WriteComm(&data[i], 1);
Sleep(100);
}
//p232->WriteComm(data, 9);
Sleep(timeout);
}
}
m_CS.Unlock();
}
Once it return from this function, the program crash!!!

The code is pretty torn up, and the For-pos statment is missing the last half - I assume it's an empty statment, since the pos1 would be changed by the GetNext.
Try commenting out the delete pCommand and the RemoveAt lines and see if that changes anything. If not, then comment out the write to your serial port (I am assuming that is what your p232 object is). If that fixes it, then it's the code for that, not the loop.

hey! i tried to remark the serial port. and, It really work???
it is my fault or VC's debug mode having error? (it work in release mode!)
thanks,
jim

I have no idea - I don't know what the code in your serial port object looks like.

You are probably corrupting some memory location, and the memory you are corrupting happens to cause a crash in debug but not release mode.
e.g. possibly allocating 10 bytes and using 20, referencing a pointer that is not set or pointing to some random memory location. Peronaly I set all pointer to NULL when I declare them, to prevent this sort of thing happening.
Either bench test the code, or run it through a program like "Bounds Checker"

I just installed Visual C++ and wrote a simple program that would not compile. I know I have to set the path right, but it seems fine to me. Here's the code, error and path description. Contribute in anyway you can.

//first c++ program
#include <iostream.h>
int main()
{
//cout << "Hello World!\n";
return 0;
}

Put cursor on error line. Hit f1. Read. Scratch head. Realize that you have failed to Read The Friendly Manual before starting. Do so. Go back and correct the totally bogus #include line. Try again, young jedi.

Dude, chill. The poster is new to Visual C, don't be a smartass when he's obviously struggling just to get started.

Looks like you're missing #include "stdafx.h" at the top of your .cpp file.

Thanks a lot, it did work. Real dumb question, how do I run the program (see the output) after compiling?

Since you are using Visual Studio.NET try the following:
#include "stdafx.h"
#include <iostream.h>
#using <mscorlib.dll>
#include <tchar.h>
using namespace System;
int main(void)
{
cout << "Hello World!\n";
return 0;
}

Hi Ezela, I see you got this particular problem solved, but please check out the Visual C++ forum FAQ (there's a link to it at the top of this page) that addresses other common compiling problems that you might encounter.

it's obvious.
look at the #include line. you don't specify what to include.
it should be something like this
#include "stdafx.h"

Hi:
I'm a newbie Visual C ++ programmer, and I'm trying to do a Simple chat using winsock.ocx, I have already done one in VB5 but now I would like to do it in VC.
Mainly, i'm having problems with .Connect metod, I don't understand what Const VARIANT &RemoteHost and Const VARIANT &RemotePort means.
PD: I have a chat example but it uses API and i would like to do it just using winsock.ocx.
Thanks and I hope you help.
This is the strangest life I've ever known.

These parameters it is asking for is the "address-of" by the "&" sign for both the RemoteHost and the RemotePort variables being passed to the function. I would suggest that you read Andrew Peace's article on pointers. A Beginner's Guide to Pointers[^]

ok, I'm on it, thanks. Um, do you know where could i get a chat sample using winsock.ocx ?  )

Sample code in C++ is probably going to use the APIs, since That's How It's Done in C++. (I don't even have winsock.ocx on my system, either)

Mike,
It should come with Visual Studio however the only place I have ever seen it used is with Visual Basic.  It's in the Windows\System32 folder.

Um, yeah, I had already seen these samples but Nish uses API  thanks anyway
