Hi,
for example make a new client socket that does not send/receive chat text, but instead only receives (binary) data.
You can derive a new class from your CClientSocket, so it's more clear that this class has a single purpose (downloading files). On the server side you might need to add more handshake to distinguish between incoming clients and incoming file requests (I don't know what Chatter and Chatsrvr do).
Propably you wanted to transfar text and binary data via one socket... but this might not be good if transfering bigger files. While transfaring the user couldn't chat anymore and the server can't send chat text. Creating a new socket for file transfar solves this problems.
Hope it helps, Moak

Hi there.
Im working on a project at the moment a sort of Search program if you will. However there is obviously going to be a problem with the system if the user doesnt use it for so many days, files will have been deleted / created / modified etc.
A solution would be a small program which logged files changes to a text file. Such as new files created, modified, moved, deleted etc. This file would be loaded by the main app and the database updated.
I have researched Visual Basic and found out about "hooks". However i dont believe these stretch to this kind of activity and as ill link to below the program below uses C++.
The following program does what i want i suppose, and the source code is free, but theres no explanation to much of it and i was wondering if anyone had tutorials / source code on this complex thing.

Thanks greatly.

Thank you soo much.
The only thing is though to make that monitor every fixed hard drive i would probably have to do a recursive search through each directory, which would be a major hit on performance for something thats running the background.
Any suggestions?
(Ive posted this without looking at the code so i may be able to work it for myself.)
Thanks.

Forgot my password!
Ive just found out that code only works on Windows NT / 2000 and XP. Which isnt any use to me as im on Windows 98 SE.
Gutted 
Thanks again for the information but if anyone has anymore information etc i would be very grateful!

I think you'd need to do the recursive search once. After that, you may be able to use this class[^] to add/remove directories of interest. It would be cool if you wrote a new version of Wes Jones' CDirectoryChangeWatcher class that supported recursive watches!

Thanks again for your help.
Damn... this is going to take some coding!
Does the code you suggested work with Windows 98?
Thanks for all your input.
Any other suggestions from other people?

hi,
I have a base class say,CEmployee and other derived classes say CManager,CDirector etc.
CEmployee is CObject derived for getting all those features from CObject.
Now,I have a list of employees (CEmployee*) in stl list<> and I serialize them.Everything is fine while storing,but while loading i cannot get the correct class and will just read CEmployee.
How to use the RTTI for serialization.

Yah, read that but not enough info.
|

When you save the objects to disk, the first thing you should serialize is the object's signature (or RTTI information), followed by the object itself. When you read back the object from disk, use a ClassFactory pattern to construct an object of the appropriate type, then serialize (read in) the object.

:-DSorry if i am a pain but its bit tricky at the moment.
Should I implement the class factory .If we use CObList or something,everything gets done from CArchive.But i am using stl list<> holding pointers.How to implement it?
|

Write the employee list to disk like this:
for (each employee in list) {
CString strSignature;
*pArchive << pEmployee->getSignature();
pEmployee->serialize (pArchive);
}
When you read the object from disk, do this:
CString strSignature;
strSignature << *pArchive;
CEmployee* pEmployee = EmployeeClassFactory.createObject (strSignature);
if (pEmployee == NULL) {
} else {
pEmployee->serialize (pArchive);
}

So this means I will have to write my own class factory.
Why can't ar>> pEmployee do the job here when a similar thing can do it for CObList in the MSDN sample DrawCli.
Thanx for answering

|

I haven't seen the DRAWCLI sample. If it works by using the streaming operator >>, it's because the Employee class's >> operator is doing the work of a class factory.

Before storing each object save an identifier for each object. Use CObject::GetRuntimeClass() and store CRuntimeClass::m_lpszClassName before actually saving an object. While loading read the string and create an appropriate instance of the class and serialize it.

How to load a pointer into the list using CRuntimeClass name?
|
|
|
|
|
How do you exactly serialize the list currently?
Gero
|
|
|
|
|
just walk all te elements using an iterator and call Serialize() against each element while storing but create a new CEmployee and serialize that and load.
|
|
|
|
|
Then do it like this:
// Storing
for each element in the list
ar.WriteString(object.GetRuntimeClass()->m_lpszClassName);
object.Serialize(ar);
// Loading
CString strType;
CBaseType *pType = NULL;
for number of objects stored in archive
ar.ReadString(strType);
// Check which object was stored based on strType
// and load it
pType = new CStoredType();
((CStoredType *)pType)->Serialize(ar);
// insert (CStoredType *)pType into list
Hope this helps,
Gero

we all know how to develop a collection of List or Array, i mean: develop real classes of them for using.
but i have no idea how to develop a collection of dictionary or map or bag etc.
i think a dictionary is based on List or Array with key sorted.
is the guess correct? can u give me some clues?
thx

yah,
thats where you begin and later optimise the operations.Ues a map rather then a list of pairs.The map can do all the dirty work for you and do it better in most cases.
