If you're reffering to the resize-grip, it's appearance is not typically changable.
What you can start experimenting with is overriding OnNCPaint, letting windows/mfc draw the grip, and then overriding just the grip to whatever you want it to be...

Hi there
Sorry for the Slopy Subject line!.
What i whant to know is the following.
I have declared a vector of person Objects
vector(person) people; //in main
I have a confrence class
class conf<br />
{<br />
public:<br />
conf(const string &nm, int d);<br />
void set_venue(venue *);<br />
void cancel_venue();<br />
private:<br />
string conference_name;<br />
int duration;<br />
venue * pvenue;
}
I Have added a data member to the conf class which is
a vector of pointers to person
vector(person *) registered;
and the following member function to register a person
who choose to attend a conference.
void register_person(????);
So this is what i must do, ok so person objects where added to people //vector(person)people;
The person running the program gets to decide who will
attend a certian confr thus needing to register this person for the confr.
By index how would i pass the address of the specified person object to my register_person(????); function and get register_person(????); to append this person object
to my registration vector(Containing only registered persons).
I am knot sure about this->
register_person(person & registered)? needs to recieve the
address of a specified(index) person object.
Help me

If your prototype for register_person is as you stated "register_person(person & registered", then all you really need to do is do "registered.push_back(®istered)". If you are uncertain of the number of persons, you should be going to the heap for allocation. Then you should be doing "news" on the Person objects and thus your prototype for register_person should be "register_person(person * registered)". You would then just need to do "registered.push_back(person)".

I’m developing a program that uses and depends on a “bought” dll. Everything worked until I got a new version of the dll and tries to use that one with it’s new shipping api.
It seams like, despite I run:
regsvr32 –u MyDll.dll
and then the new dll with the same name
regsvr32 MyDll.dll
the new dll can’t get used at runtime.
All tips are welcomed!!!

This is too vague to be able to offer any assistance on. What do you mean by it can't get used?

It crashes, when the program (should) call the dll
It actualy work on my developing cpu, so it's not wrong on the new dll.

Technically, DLLs don't get called. They get loaded into the address space of an application, and then exported functions get called. So, is it crashing on the LoadLibrary() or GetProcAddress() call? If neither of these functions are being used, are you implicitly linking instead.

I run:
#import "MyDll.dll"
and here comes the faliure:
if( SUCCEEDED( hres = m_IPtr.CreateInstance("MyDll.Stuff") ) )

Does m_IPtr have a valid value? What values does CreateInstance() return?

My code looks like this:
if( SUCCEEDED( hres = m_IPtr.CreateInstance("MyDll.Stuff") ) )
{<br />
*_teststream << "handle to connection open - hres (S_OK) = " << ITOA(hres) << endl;<br />
}<br />
<br />
LPVOID lpMsgBuf;<br />
<br />
FormatMessage( FORMAT_MESSAGE_ALLOCATE_BUFFER | FORMAT_MESSAGE_FROM_SYSTEM,<br />
NULL, hres, MAKELANGID(LANG_NEUTRAL, SUBLANG_DEFAULT), (LPTSTR) &lpMsgBuf, 0, NULL);<br />
<br />
*_out << endl << "DEBUG INFO: HRESULT = " << (char*)lpMsgBuf;<br />
<br />
delete lpMsgBuf;<br />
And the output on the failing cpus is:
DEBUG INFO: HRESULT = Ogiltig klassträng
"invalid classtring" (or something in english)

Does "MyDll.Stuff" exist under the HKEY_CLASSES_ROOT registry key?

Are you saying this is a release only problem? Or that it only happens on a non-development machine?

Um, If you use Depends.exe it will list the libraries that MyDLL.dll uses. Are they the same on both systems?

I think that your registry is corrupted. Try to use any tool to verify. You can find over internet these tools. 
But, you can do it manulay.
- Verify if the class Id are the same.
- Backup your registry (Its corrupted, but just save)
- If are, look in registry for the all class Id and Interface Id for the Dll (Realy realy hard work), and delete All.
- Delete all temporary files (sometimes its works)
- Shutdown your system
- Try to install new DLL
- Registry new dll, recompile your program (Rebuild All)
- If not works, you have serious problem, may be, you should format your PC

How do I get the class Id?

- Registry your dll
- Look in registry for your DLL Name (MyDll.Dll)
- Try to search any entry like this {5EFCDACB-46BD-4904-B8AF-4DD75D5C0144}
- This is an example of GUIID
Its hard work .....
If you do it very well with attention, probably, you will get a success.

Does the registration work? i.e. are there any errors reported back from regsvr32?

Yeah, both the unregistration of the old one and then registration of the new one, works according to the success message...
