use _getch(), the header file is conio.h

:) Maybe I made something wrong, but it just works fine in my computer. My compiler is VS2008.

Here "from" and "to" are constant strings exactly, so the codes below would be mistake. "*to++ = *from++". If you declare "from" and "to" as array of string, your program would work fine. Just like: char from[] = "c plus cplus"; char to[] = "oooooooooooooooooooooo";

If you need random access operation frequently in your code, use vector. If you need insert and delete operation frequently, use list. And map should be use when you want to identify a value by a key(mobbish).

Yes, not #pragma pack(1). I put it in my program, and the output was "22". :)

Thanks. I add "#pragma pack(4)", and it works as I wish.

Thanks for your answer.

#include <iostream> using namespace std; class CTestA { public: virtual void FuncA() {} private: int m_iValue1; char m_cValue1; int m_iValue2; char m_cValue2; double m_dValue1; }; class CTestB : public CTestA { public: virtual void FuncB() {} private: }; void main() { cout << sizeof(CTestB) << endl; system("pause"); } Why the output is '32', while my expected is '28'.

If your compiler is VS200X, you can right click the control, and click the "Add Variable" in the pop menus. Then it will pop out a window, and you can set the property in it. If your compiler is VC++6.0, select the control, and in the "View->Class Wizzard->Add Member", I hope I don't misremember.

Yes, it can. you can set the property of the control to gain what you want. I forget the details, but I am sure it can. My computer do not have a compiler, so I can't take a test.

LVFINDINFO temp;
CString ff;
temp.flags = LVFI\_STRING | LVFI\_PARTIAL;    
CStdioFile fileh;
fileh.Open(L"C:\\\\srvc.txt", CFile::modeRead);	
int i;
do	
{		
    if(fileh.ReadString(ff)== NULL) 		
    {			
        break;		
    }	
    temp.psz = ff.GetBuffer();	
    i = m\_objListCtrl.FindItem(&temp);
    if(lstrcmp(m\_objListCtrl.GetItemText(i, 0), temp.psz) == 0)	
    {		
        m\_objListCtrl.SetCheck(i, TRUE);	
    }		
}
while(ff.GetBuffer() != NULL);		
fileh.Close();

This can work in my computer, but I don't guarantee it could work in your computer. And by the way, I am in school now, but tomorrow I'll back home(There is no computer in my house :) ). It means I could not use computer for a long time. And I can't solve problem together with you, I'm sorry for that..

Before you changed the "temp.flags = LVFI_PARTIAL|LVFI_STRING;" to "tem.flags=LVFI_STRING;", it's a wrong case exactly. But now it isn't. :)

You are right. :)

I think your code still has some problems. Consider the situation below: There are two items in CListCtrl. 111.111.111.111 111.111.111.11 And you enter 111.111.111.11 to insert the new item, see what happen. If I am right, it will insert successfully!!That may not be what you want.

BYTE m_M1, m_M2, m_M3, m_M4;
TCHAR ss[50] = {0};
UpdateData();
ipAdd.GetAddress(m_M1, m_M2, m_M3, m_M4);
_stprintf_s(ss, _T("%d.%d.%d.%d"), m_M1, m_M2, m_M3, m_M4);
int compare;
for (int i = 0; i < ipList.GetItemCount(), ++i)
{
compare = lstrcmp(ss, ipList.GetItemText(i));
if(radBut1->GetState())
{
if(m_M1 && m_M2 && m_M3 && m_M4 && compare != 0)
{
ipList.InsertItem(s++, (LPCTSTR)ss);
ipAdd.ClearAddress();
}
}
else if(radBut2->GetState())
{
if(compare == 0)
ipList.DeleteItem(i);
else
MessageBox((LPCTSTR)L"Error: Address not found", (LPCTSTR)L"Delete Address", MB_ICONWARNING | MB_OK);
ipAdd.ClearAddress();
}
}

This is the final version. :)

if(i != -1) ipList.DeleteItem(i);

Relpace the codes with: if (i != -1 && lstrcmp(ipList.GetItemText(i), temp.psz) == 0) { ipList.DeleteItem(i); }

ipList.DeleteItem(i);

What's "s" means? The last index of CListCtrl? So if it's, then here

rahuljin wrote:

ipList.DeleteItem(i);

after deleting a item, you must also descend "s". I don't know if this is the reason.

you solve the problem by yourself, congratulation :) . maybe you can try replace the follow codes by "srvc.Write(ff, 2 * lstrlen(ff));", it works too in my computer.

while(i) { srvc.Write(&ff[j++], 1); --i; }

You can try this, open the "srvc.txt", and select all text, and copy them, and open anthor TextEditor(Edit Plus), and paste. If still there is no new line, then I have no ideas. It's seems that Microsoft define a new line as '\r\n', while in Unix it's '\n'.

You can try veiwing the text in Edit Plus or other text edit software.
