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.

Hello,
How to get the print feature for different doc templates.
Just handling id_file_print doesn't do anything.Could any one help by listing the steps or something.
Bye.

In MFC, its the view which handles the printing of data from a document. All CView derived class's have the OnPrint() member function, which gets called once per page of output. You have to implement that printing code in this function for your document template view class.
Take a look at the examples in the printing section here.

The makehelp.bat file generate the yourprojectname.hm file used by the help compiler to match topic ID's with the dialog/control ID's in your application. You only need to run this .bat file when you add new ID's to your project etc.
HCW.EXE is the microsoft supplied help compiler. On my PC this is installed in Program files\Microsoft visual studio\common\tools. You may need to correctly setup your VS environment variables so that it can find the tool when you come to compile your help file.
Goto Tools:Options in VS studio. Sleect Directories and the sub option Executable files. Make sure the path top the location of your installed tools directory is present.

In windows registry (RegOpenKeyEx) what means KEY_ENUMERATE_SUB_KEYS? Is this more than reading it?
I'm confused when using KEY_READ or KEY_QUERY_VALUE. Thanks
