But in that case the exported functions names become added with some ?@# symbols. They are not exactly the names as in the source code

Hi All,
I want to move mail to another folder.
I am getting exception in code:
_MailItemPtr mailPtr;
..
..
..
MAPIFolderPtr temp=g_pNsp->GetFolderFromID(_bstr_t(Selected_Action_Folder.szEntryID));
mailPtr->Move(temp);

did you debug to check if values are initialized properly and why is it crashing? If not, this may be the right time to do this activity.
You need to google first, if you have "It's urgent please" mentioned in your question.

Please I need help on this, I'm new in C++.
Here are the details:
1. I have a base class and 3 derived classes:
Base class
class CRepositoryData
{
...
};
Derived classes
class CUser_data : public CRepositoryData
{
...
};
class CLock_data : public CRepositoryData
{
...
};
class CReferences_data : public CRepositoryData
{
...
};
2. My declaration for my classes in my function uses CList <>
main()
{
CList <CLock_data,CLock_data&> listLockDataTemp_L;
CList <CReferences_data,CReferences_data&> listLocationDataTemp_L;
CList <CUser_data,CUser_data&> listUserDataTemp_L;
if(Lock)
{
CreateBatchToSend(
dynamic_cast<CList<CRepositoryData,CRepositoryData&>*>(&listLockDataTemp_L));
}else if(CReferences)
{
CreateBatchToSend(
dynamic_cast<CList<CRepositoryData,CRepositoryData&>*>&listLocationDataDataTemp_L));
}else
CreateBatchToSend(
dynamic_cast<CList<CRepositoryData,CRepositoryData&>*>(&listUserDataTemp_L));
}
}
3. Is this code possible for my CreateBatchToSend()?
BOOL CreateBatchToSend(CList <CRepositoryData,CRepositoryData&> *pListRepData_P)
{
...
CList <CLock_data,CLock_data&> listLockDataTemp_L;
listLockDataTemp = dynamic_cast<CList<CLock_data,CLock_data&>*>pListRepData_P;
...
}
4. I am trying to create a function that can take those 3 derived classes in a list by using the base class as the argument and then use dynamic cast to revert back to their respective class.
Do I need to use other containers to implement this?
Any suggestions would be very helpful. Thanks a lot...

I am not sure I understood your question but what you are trying to do is not really correct. You can't cast to CList<CLock_data,CLock_data&>* from a CList <CRepositoryData,CRepositoryData&> *. These are two different types (even if the class used for template arguments are parent/child).
A better approache would be to use polymorphism: instead of manipulating a list of CRepositoryData objects, simply manipulate a list of pointers to CRepositoryData objects. This way, the pointer can point to a CRepositoryData object or to a child object.
This has also another advantage: all the lists can be manipulated the same way (and you could maybe even reduce them to one single list).

A ok. You're right. I need the pointer to CRepositoryData object.
My main problem is i have this 3 different functions that will call one function(Create_Batch_to_Send()) with CRepositoryData as the argument:
Function1 - calls Create_Batch_to_Send(CList<CUserdata,CUserdata&>*listUserData)
Function2 - calls Create_Batch_to_Send(CList<CLockdata,CLockdata&>*listLockData)
Function3 - calls Create_Batch_to_Send(CList<CReferencedata,CReferencedata&>*listReferenceData)
I want Create_Batch_to_Send() function to handle those 3 list. That's where my problem occurs. I dont know what argument i should use.
Sir please can you give me an example on how to make this pointer to CRepositoryData as an argument to
Create_Batch_to_Send(). Thank you very much...

void Create_Batch_to_Send(const CList<CRepositoryData*> & listUserData)
(it is also better to pass the list by reference, so that you don't make a copy of it).
But of course, all your lists should manipulate pointers and not objects. Thus, you will need to create your objects dynamically (using new) and not forget to delete them once you don't need them anymore.
In your function, it really depends what you have to do with the objects but in most of the cases, you probably won't need to cast anything.

You could make Create_Batch_To_Send a template function:
template<class ListElementType>
BOOL Create_Batch(CList <ListElementType,ListElementType&> *pListRepData_P)
{
}
This does have the obvious disadvantage that you'll have multiple copies of the function.

Our coding rules does not allow me to make the function a template but thanks anyway.
I cant seem to make it work on making my list and passing it to the batch function.
I call void Create_Batch_To_Send(const CList<CRepositoryData*> &listRepData)) considering the earlier reply.
myfunc()
{
CList<CUser_data, CUser_data&>* UserParentlist;
UserParentlist = new CList<CUser_data, CUser_data&>;
Create_Batch_To_Send(UserParentlist);
}
It does not work. Can you provide me with the exact syntax. Many thanks to all.
I think passing a CList derived class to a function that has an argument of the CList base class
is not possible. since inside my create_batch_to_send() I must be able to differentiate those 3 derived class. The first thing I did was like
create_batch_to_send(IN DATALIST dataType_P,IN POSITION &startPosition,
IN int number_of_Record_To_Copy,
OUT CList <CUser_data,CUser_data&> *plistUserdata_P,
OUT CList <CLock_data,CLock_data&> *plistLockData_P,
OUT CList <CReferences_data,CReferences_data&> *plistLocationData_P)
The enhancement that i want to make was to use the base class of these 3 classes as one argument only.

Any sensible reason for that coding rule, or the usual anti-template FUD?
blontek wrote: I think passing a CList derived class to a function that has an argument of the CList base class
CList is NOT a base class. It's a template class. The instantiated list classes for your different data types have no common base class - nothing in common whatsoever, except that they've been created from the same template.

Why? The web browser control is always Internet Explorer under the hood, even if you've uninstalled IE. It doesn't magically use your default browser.

Thank you. Yes, it doesnt magically get setting from default browser.
My question is, how to make Webbrowser to get setting from Firefox, if it is make default browser? Is this possible or not?
Thanks..

By making sure that the Internet Explorer proxy settings are the same as the Firefox settings...yourself.

Hi,

Try BoundsChecker or Purity

I prefer more to use Deleaker - russian alternative to BoundsChecker, it works more perfectly.
