I would need to forcibly save and restore cookies while IE is running.
Is there a way to program that ?

With sufficient thrust, pigs fly just fine. However, this is not
necessarily a good idea. It is hard to be sure where they are going to
land, and it could be dangerous sitting under them as they fly
overhead. -- RFC 1925
 
Thanks,
Sorry for the delay.

I just did the code Which consist of an enumeration and retreival,
But InternetGetCookie does not seems to work.
The enumeration (FindFirstUrlCacheEntry) works though.

Perhaps, I do not understand how to use it properly?
I had a GetLastError of (998) ERROR_NOACCESS


Any help or sample code of usage would be greatly appreciated.
Thanks.
Denis

ERROR_NOACCESS means you are passing a NULL or invalid pointer. Show how
you call InternetGetCookie

I see :
InternetGetCookie (_T("my.yahoo.com"), NULL, (LPTSTR)&Buffer, &CookieSize);

I do not know what to put as Name?

How is Buffer declared? If you have to cast, you probably got it wrong.

You mean the second parameter? The documentation says "Not implemented",
so any value should do. NULL is perfectly fine.

Oops!

I just changed &Buffer to Buffer but it is still the same...
Buffer is define as this:
BYTE Buffer [(64 * KB)];

???

Do you initialize CookieSize to the length of the buffer before calling
the function?

Note that the size should be in TCHARs, not in BYTEs. TCHAR may be 1 or
2 bytes depending on whether you build ANSI or Unicode build.

I am in unicode so...
I have divide the CookieSize by 2 - 2;
still no luck???

This time I had an error of 12006 which is not define in error lookup.

I even try to place the call at the begening of the software...
Not working ...

Hummm! What do you think?

That would be ERROR_INTERNET_UNRECOGNIZED_SCHEME. You are passing
"my.yahoo.com" as the first parameter - make it "http://my.yahoo.com"

Yes!


It worked finally.


Thank you very much.

On a side subject:

I need to stores/retrieves cookies independently of the user name created in windows.
Example: Let say I create the user 00001 and saves its cookies.
Then later I would call that user 00002 and restore it's cookies from 00001 for example.

In your opinion would my strategy old ?

Regards,
Denis

InternetGetCookie, InternetSetCookie et al use the cookie store of
whatever user account your process is running under. So you can
impersonate one user, read all her cookies and store them somewhere,
then impersonate another user and set cookies on her behalf.

I have been trying.
There another issue, that perhaps you can help me.

On yahoo, I setup a personal page and normally it recognizes me.

When I use those routines it does not?


Plus I can see the cookies in the cookies folder. When I use the routine it does not?

Thanks,
Denis

Do you set persistent cookies? That is, does the cookie value passed to
InternetSetCookie[Ex] have expires= clause? Without such a clause, you
are setting a session cookie - temporary in-memory cookie that is only
active within your process. For an example, see

Right now I am just Storing them as I got them from InternetGetCookie.

I am guessing That I have to add a line saying for how long from FindFirstUrlCacheEntry().
in the structure INTERNET_CACHE_ENTRY_INFO
Is this right?
And Is this the only thing I am going to need?

Thanks,
Denis

Right. You can use InternetTimeFromSystemTime to format the time string.
And Is this the only thing I am going to need?

I believe so.

BTW...

Right now I am truncanating the user name@ and replace it by "http://"
Is there any cases where that should be "https://" if yes how would I know?
