Detected memory leaks!
Dumping objects ->
{850} normal block at 0x01363F28, 16 bytes long.
Data: < > CD CD CD CD 00 00 00 00 00 00 00 00 00 00 00 00
Object dump complete.

I have a base class CCommonDlg derived from CDialog
then let CRegesterDlg derived from CCommonDlg
then let CEditUserDlg derived from CRegesterDlg
when I write this

m_pEditUser = new CEditUserDlg;
m_pEditUser->Create(CRegesterDlg::IDD,this);
m_pEditUser->SetUserInfo(&m_stUserInfo);

The memory leaks!
why ?

Solution 3

There is something 16 bytes long, that was allocated and presumably never initialized int the first 4 bytes that have never been deleted.

This is the only thing we can deduce from your post.

Buy a memory leak finder tool. There are several available.

There are a couple of free tools, but most are restricted to just a few OSs (the best are for Linux), and many are difficult to use, or at least come with little or no documentation. I've read an article that compared such tools a couple of years ago, but unfortunately can't find it any more. Try google for it.

Solution 6

Can you make m_pEditUser be not a pointer, but a stack variable? Then you would not need to create it with new and worry about deleting it.

You could try to find the code region of your leak...

Just comment the function bodies,
function by function, until you have a "white" exit :)

Then - please analyze the last commented body,
find the leak-resolving line (usually: new/constructor/subfunction)
and improve it or/and post it here :)

You have memory leaks. You have no idea what you're doing, or you'd know that we can't help you based on this. Perhaps you need to read a basic C++ book on memory management ? If you want to post actual code, perhaps we can try to help you.

Also, don't push answer if you're not posting an answer. Edit your post to add detail. A lot of people only answer questions with no answers, they assume a response means you've been answered.
