lookup the MX records in DNS. If this isn't what you want you have to ask the user in general. You will have to search a little more to find out how to do this (and if this really gets what you want)

Hi!
I have an object which is a container for one or more other objects. I want to serialize my container to disk and serialize the contained objects along with it.
This is what I have:
class CBook;
class CSubject
{
public:
CSubject(){}
~CSubject(){}
protected:
CList <CBook, CBook> m_Books
};
Can someone tell me the best way of doing this?
Must I want to make my CSubject and CBook classes inherit from CObject and then write a serialisation function for each?
Should I just write all my CBooks and index them to the CSubject or is there a proper way to serialize a CSubject object which then will serialize all the CBook objects contained by the CSubject object. Must I want to store pointers to the CBook objects in my list or do I store objects? I think it must be the objects.

Inherit CBook from CObject. Then create a similar Serialize(..) function for your CSubject. Call m_oBooks.Serialize(...) in it. If you have pointers in CBook class, i think you need to implement an override for CBook::Serialize(...) too.

OK but I have one or more CSubject objects and I wish to serialize them all to disk.
So I have a data file which is called library.dat and I want to serialize to this file all my CSubject objects with all the CBook objects each CSubject object contains.
Is this something that CObject will do for me if all my object data members are simple?

Method 1
- Inherit your CSubject from CObject
- Put all your CSubject objects into an array like CObArray
- To save them, call m_oMyObArray.Serialize(...)
Method 2
Assume you have implemented a save function of your CSubject as below:
void CSubject::Save(CArchive& ar)
{
m_Books.Serialize(ar);
}Just call Save(...) for each of your CSubject objects, passing in your CArchive object. For example,
void SomeFunction()
{
CFile oFile;
if(oFile.Open("C:\\library.dat", CFile::modeCreate | CFile:modeWrite) != FALSE)
{
CArchive oArchive(&oFile, CArchive::store);
oMySubject1.Save(oArchive);
oMySubject2.Save(oArchive);
oMySubject3.Save(oArchive);
oArchive.Close();
}
}

You need to override Serialize for your CBook class. e.g.
void CBook::Serialize(CArchive& oArchive)
{
if(oArchive.IsStoring() != FALSE)
oArchive << m_iMyInteger << m_dMyDouble;
else
oArchive >> m_iMyInteger >> m_dMyDouble;
}

Dear guys,
Some MFC program runs well.
Someone uses the task manager(by cntl + alt + del) and selects my mfc.
And than, kill my program.
Can I protect my process from the task manager's kill signal?
Additionaly, i don't wanna use the windows's service mechanism(a.k.a daemon)
Thanks,

I think there is a way you can do it but you will need windows hooks.
The cbtroc call back function monitorises when windows are destroyed and get the handle,module filename.
Read More about this in my article about the simple fireawall. There I explain more about windows process hooks.
If you can't handle please contact.

SIG_KILL (or another name like that) cannot be catch. this is to prevent any restive process to stay in memory wastefully.

If this was possible, no rogue process could ever be killed. We'd have viruses running rampant!

Hello,
I have two program call it A.EXE and B.EXE . B.EXE will actually invoke the A.EXE through CreateProcess API and establish some piping. If you familiar with wsinetd - Windows Simple inetd daemon or inetd. That is exactly what B.exe does. B.EXE listen to a port number and spawn process based on port number it accept from client which in this case the process been spawned is A.EXE. The communication between A.EXE and B.EXE is through piping. I can get the thing up but the problem now is I need to debug A.EXE in the IDE (meaning I can set break point and etc) cause basically there is where the logics lie.
I have generated the debug info for A.EXE and B.EXE and it is denifitely in debug mode. The compiler setting is /MTd /W3 /DWIN32 /ZI /Od. The PDB file for A.EXE and B.EXE are created and stored in the same directory as A.EXE and B.EXE. I have step into B.EXE no problem but I could not step into the spawned process A.EXE. Any remedies. I have thought of using remote debugging but no luck. Any debugging gurus out there that could shed me light?
thank you.

Maybe this would work for you:
DebugBreakProcess
The DebugBreakProcess function causes a breakpoint exception to occur in the specified process. This allows the calling thread to signal the debugger to handle the exception.
BOOL DebugBreakProcess(HANDLE Process);
Have B call this soon after it launches A...

Actually, your answer is the same as my colleague but my colleague mentioned DebugBreak instead. I have tested it. It doesn't work on DebugBreakProcess but DebugBreak. I think DebugBreakProcess will only work on another process.
thanks by the way. A 5 for your quality reply.

Hello !
I have a dll written in C++ that is used in a VB application. In one function, I send a string (BSTR type, so it has the VB format), and I want to convert it into a char* string. How can I do that easily ?
Thank you.

|

I think you can do this
<br />
BSTR temp;<br />
char* str = (char*)_bstr_t(temp);<br />

Ok thanks, I will try this

The BSTR Value is UNICODE Value, you should use a routine to convert from Unicode to ANSI.
Using cast method, you can lose data, and you can have memory leaks.
The best way to do it is :
USES_CONVERSION
char* a = W2A(bstrvalue);
IMHO you should use UNICODE type, like wchar ao rather than char.
To prevent to have 2 types, you can use TCHAR.

I do this:
m_valueSearchBox.SetWindowText(initValue);
if I do this the initValue string (CString) wil be selected, but I need the cursor behind the text so you can type an appending text.
SetSeldoesn't seem to work?
tnx.

Why shouldn't it? Try this:
CString str;<br />
m_valueSearchBox.GetWindowText(str);<br />
int nPos = str.GetLength();<br />
m_valueSearchBox.SetSel(nPos, nPos, TRUE);
Best regards,
Dominik
_outp(0x64, 0xAD);
and
__asm mov al, 0xAD __asm out 0x64, al
do the same... but what do they do?? 
(doesn't work on NT)

tnx for the reply, but I'm afraid I must dissapoint you.
I do this:
<br />
int pos = initValue.GetLength();<br />
m_valueSearchBox.SetWindowText(initValue);<br />
m_valueSearchBox.SetSel(pos, pos, TRUE);<br />
(it's SET not GET, but not important).
What happens is that the cursor is behind the text, BUT the text is selected, so if you start typing ...

I think the positions in SelSel are index based, so try:
m_valueSearchBox.SetSel(pos-1, pos-1, TRUE);

tnx for your reply, but I have to disappoint you too.
I tried SetFocus() and SetSel with about every value possible.
SetSel(-1, nPos, FALSE/TRUE); (nPos = length, length-1 ,... as first and/or second parameter etc.)
It just doesn't seem to work.
Normally it should, but maybe it's due to something else (processor or something)
I don't know, I'll keep searching
