Hi, first of all, you can edit you first message to correct possible errors, instead of adding a new message.
On the other hand...
Why are you using the "" when you create the pointer? Is it a typo? Or are you really using them in your code?
I recommend you to take a look onhttp://www.codeproject.com/KB/DLL/[^]
This user[^] wrote a serie of articles around DLLs that I found quite usefull, check it out as well

Ok! Next time i'will edit the message to correct.
For the other hand..
In the project i go to "Insert new class"
Class type : Generic Class
Name : COggetto
Derived from: CObject As Public.
In the .h file i put my variables (are 2 CString)
The in the .cpp i put my code:
COggetto* pOggetto = new COggetto;
pOggetto->m_sCodice = "000001"
When i'm in running i see that the pointer pOggetto is created after the "new" but on the instruction " pOggetto->m_sCodice = "000001"
the project crash.
Thank's for your time!

Do you mean pOggetto is a valid pointer (Did you check with the debugger?)?
How is declared m_sCodice?

You said here that such pointer is NULL.

that's ok.
I see on quick watch that the variables on the pointer are null.
Sorry for my statement!

If pOggetto is null then you should discover why it is such.
Could you use the debugger to step inside the object constructor?

Can you post the beggining of your both COggetto.cpp and COggetto.h (I mean the section of variables, constructor, destructor, operators... but without possible member functions done/added by you)
When you use the Wizard to add classes, it implements some standard things, but most of the times you need to add/modify part of them in order to get your class working ok.
Regards.

Could you please post the actual code (either the CobOggetto constructor and the pOggetto initialization) using the code block button?

this is likely way more complex than you want - but its the only thing I can remember that Ive seen supposedly do it
http://vbmhwb.sourceforge.net/[^]
search for WBAuthenticate on the page
'g'
ps.. Im hoping it shows you the general method, Im not suggesting you can use the actual code here
|
|
|
|
|
thanks a lot for your answer...
i couldn't find in the site you gave where to d/l the code that implements the WBAuthenticate...can u direct me or give me direct link please
thanks again

and see if you get a hit - I just checked the link and it works for me

cool, now, download vbMHWB.zip, unpack it and look at vbWB.cpp, searching for WBAuthenticate

One more thing if i may...
i was able to work with IAuthenticate implementation (the method 'authenticate' did the trick)
problem is that the actual authentication occurs only once, and if the user and password are incorrect i don't reach the method 'authenticate' again.
what am i missing wrong here?
thanks again

I would have thought you'd have to resend the http request again - but Im no expert
'g'
|
|
|
|
|
one would thought that when user name and password are incorrect either in the callback would return proxy_authenticate_error or authenticate will be called again
ok i will dig more into it
thanks again

Im familiar with a certificate error where you intercept the error, search through the local cert store for a matching certificate - but then you have to re-broadcast the original call, with the cert details filled in
(hence why my suggestion)

Hi,
I am in confusion about vitual table content....
1. Is it hold the address of member function (non virtual) and virtual member function?
2. When It is created?
3. Is it seperate for all classess?
|
|
|
|
|
Virtual table holds the address of all virtual functions that belong to a class.
A class having at least one virtual function will have an associated virtual table.
The virtual table is created during compile time and it is initialized in the constructor call.
My article will probably help you - Polymorphism in C[^]

1. Vtable holds the address of the virtual members only.
2. It is created on compile time.
3. Yes
Just read this article so that you get clear with it [^]

I want render a band from a richedit control into a bitmap.
I have tried the formatrange/display band code, but if I render to an in memory dc it always comes out blank. If render to a printer DC I get the contents. The goals is to have background images and watermarks appear on the rtf content.
