When I have seen this question there wasn't any answers, but when I finished answering the post(I tried the code in VC to be sure if it's working), there was already plenty of answers .

To avoid this error, you can 'forward declare' class B.
class B;
class A
{
public:
B GetB() { return B(); }
};
class B
{
public:
A GetA() { return A(); }
};

I have listctrl with rows(vary) and 3 column
let say first column is a,second is b, third is c;
I want the data of a, b, and c of the row.
so i tried the following ways
<br />
for(int i=0;i<numberOfRow;i++)
{<br />
CString dataA = myListCtrl.GetItemText(i,0);<br />
CString dataB = myListCtrl.GetItemText(i,1);<br />
CString dataC = myListCtrl.GetItemText(i,2);<br />
<br />
LV_ITEM lvitem;<br />
ZeroMemory(&lvitem, sizeof(lvitem));<br />
lvitem.mask = LVIF_TEXT | LVIF_STATE;<br />
lvitem.iItem = nIndex[i]; <br />
lvitem.iSubItem = 1; <br />
myListCtrl.GetItem(&lvitem); <br />
<br />
dataA = lvitem.pszText;<br />
}<br />
both ways gave me let say dataA value as junk. How can I get back my item text???
Thanks

Can't say why the first way is failing, but the second doesn't work because you're not providing a buffer for the control to store the text in. You need to set pszText and cchTextMax to the address and size of the buffer before calling GetItem().

If theres a problem with file strFile0 and an exception is thrown, I want the error message to have the name of the faulty file. This name is gotten in the try block. I dont think I can pass it in the catch argument:
catch(CFileException e, strFile0)
{
CString temp;
temp.Format("Error opening file : %d", e.m_cause);
AfxMessageBox(temp);
return -1;
}
}
So how do I communicate it to my messagebox in the catch block?
Appreciate your help,

catch(CFileException e, strFile0)
{
CString temp;
temp.Format("Error opening file : %d ", e.m_cause);
AfxMessageBox(temp + e.m_strFileName);
return -1;
}

Thats convenient! You did however mean to remove the strFile0 argument I was trying to pass in, right ? I am off to look up CFileException and see what all it exposes...
Many thanks,

CFileException has m_strFileName member which contains file name.

Is it possible to perform development in Visual Studio by having the libraries of a third-party component on a remote machine?
Any suggestions?!
|
|
|
|
|
Aehm, add the path to the library folder on the remote machine to your LIB path?

Hello,
If an ostream is open and a write operation completed, then a flush called, is the data 100% committed to disk or is there a delay?

The data is 100% commited to disk.

While stream flushes *its own* buffer, the OS can cache the data. Is there any requirement on standard file streams which makes them call API like ::FlushFileBuffers on close? I did quick grep and was unable to find fflush/_commit/FlushFileBuffer calls in C runtime sources for fstream.

flushing an iostream causes a call to sync for the managed streambuf object. Dinkumware's doc for basic_filebuf (here[^]) state that basic_filebuf::sync calls in turn to fflush . Of course, the ultimate test is to check it directly on the source code, but alas I don't have my Visual Studio handy right now.

can anybody plz help me with locking the PC ...thru Bios or any other way so that nobody can access it...It should not detect any Hard Disk. (dont tell me bios password since it can be cracked with jumper settings). I need to lock a PC anyhow bcoz when i go away to home from my PC somebody else come and start working on that.
If I change Windows 2000 password then they will format the Hard Disk and start working again.
IF I keep a BIOS password then they can crack it by changing jumper settings.
what i need that computer should be hanged and nobody can easily guess that what might have happened to the computer...why it was not working?

|

Sounds fishy....
How exactly would you restore the computer so that 'you could start working again'?
|
|
|
|
|
If he puts a password they format??? what use then?? Dont they have other machines??
Fishy to me too!

there is NO solution if someone can open your PC case.
The best solution is bios password and padlock on the case.
|
|
|
|
|
Our Dell laptops (I have an Inspiron 8100) have hard-disk-based passwords.
If you don't know the password, the harddisk won't start to spin. This is not resettable by jumpers.
Of course they can always replace the hard disk.
Enjoy life, this is not a rehearsal !!!
