That is not very elegant because you will need to cast the void pointer back to its class when you want to delete it (otherwise, the destructor won't be called).

A better way to do that (if polymorphism is needed) is simply to have a list of pointers to the base class. So in that case when you delete all the elements of the array, the destructor will be called.

I think u shd not use char * as it is not supported to UNICODE
Either use CString or TCHAR

Only this much I know Frown | :(

TCHAR is not UNICODE. it is only if UNICODE is explicitely defined. otherwise, it is ANSI char...
but it is the stuff to use Cool | :cool:

Vector of class with contractor

Ohad Cabiri22-Jan-07 22:48

22-Jan-07 22:48

Hello,
I want to start a vector of calsses with the same contruct
Lets say this is my class :

<br />
class aaa<br />
{<br />
public:<br />
	aaa(int i){  m_iA = i;	}<br />
private:<br />
	int m_iA;<br />
};<br />

and I want now to do 5 classes with the same contruct:

<br />
aaa* f = aaa(2)[5];<br />

I have to do a loop for this (pointer of pointers etc.) ?
Or it is possible to do this somehow in a short way ?
Thanks,

In fact if you don't have a default constructor, the only way to do that is to have an array of pointers to your class:

aaa** pArray;
...
...
pArray = new aaa*[5];

And then loop through your array and create all the classes:

for (int i=0;i<5;i++)
   pArray[i] = new aaa(Value);

Of course, you will need to delete all these instances AND the array.

If a statically-allocated array is acceptable, you can do:

aaa stuff[] = { aaa(2), aaa(2), aaa(2), aaa(2), aaa(2) };

Hi,

I am using IADS component to query about the user information from a local machine.

Sometimes, When i call ADsGetObject method, it takes more time to query about the user. But some times it happens quick.

I am querying about an user who is created in the local machine.

What is the reason for this? How can i solve this problem.

Any help would be very much appreciated.

Thanks.

Hi,

There are two APIs for searching a folder
FindFirstFile & FindNextFile

or there is an MFC Class CFileFind, which is almost like a wrapper to above mentioned APIs. you can go through the documents of these APIs.

In the dialog editor, right-click on your listbox and search in the settings. There should be an option to sort the list. Uncheck the check box 'Sort'.
