Haven't tried it and don't know if it will work but the path I would head down is below. Keep in mind I've never done this and have not worked in C/C++ for a while and when I did it wasn't web related.
I'd call CHttpRequest::GetURL[^] and I would try to get "http://www.websiteofinterest.com/favorite.ico" if true you are good if false handle it and try something else. I have not tested this nor do I know if it will work but it should without any trouble.
MODIFIED: That actually doesn't look like the right function to use. I think that's a server-side call you would make. In theory my idea holds find the right function and you should be good to go.

I bow down to the code-frog for responding :bow down:, but unfortunately that's not exactly what I'm looking for.
I already know how to get favicon.ico using WinInet (or whatever).
The thing is that the spanky way to specify a favorite icon for a site is to insert it's reference into the HTML. So looking for favicon.ico doesn't necessarily work. I know how to parse the HTML to find this info, but that's a lot of work - especially since it should already be available via a COM interface at my fingertips.
IE exposes practically everything via COM interfaces... so there has to be something to figure out what the Favorites Icon is for a particular web page (isn't there???)...
Or am I just asking questions without answers?

Oh I believe there's an answer alright I'm just not sure it's a "documented" answer. I reread your post and with your follow-up comments it makes more sense. Unfortunately, I don't have an answer for it. I'd find the object model for I.E. and start looking.
This looks interesting Microsoft[^] and in that link the "Associated Browser Reference" looks good. I'm sure you have seen both of these but that's about as far as I can go. I've got a super tight deadline for the morning.

K, thanks. Perhaps Microsoft actually didn't create a documented method to figure out the favorite icon for a web page. 
Seems strange that they didn't, but perhaps it is true and everything has to be done the hard way.

Well, I have at least made an effort. Been a very long time since I've done this. When I get a chance I'll check this thread and see if you have an answer. If you don't I'll email a few people I know at Microsoft and see if an answer (from the inside) can be obtained. Hopefully you don't have to wait that long...

I'm about as far from a web or web-related expert as it gets, but I'd bet you could get to the entirety of the HTML document (/head/link tags included, where the favicon tag will be) by using the DOM heirarchy provided by the IE COM interfaces.
Unless, of course, this process is what you were referring to as 'parsing the HTML'.

Thanks! Yeah - I'm already parsing DOM.
Just figured that perhaps IE already had this information and is making it available via COM (like most everything else). 
DOM is cool, but unless you do some fancy stuff it is pretty much "after the fact". If the bowels of IE already kept track of the favorites icon -- then duplicating that effort is kind of unecessary, complicated, and also slow.

IE6 only gets the favicon.ico when you create a Favourite. One of the common complaints is that IE loses Favourite icons over time, because they're stored in Temporary Internet Files and so either get replaced by newer content as the cache fills up, or get lost due to one of the many cache corruption bugs in IE6. You can get it to recover them by dragging the icon from the address bar and dropping it back on there.
It's probably possible to get the right icon from a favourite/URL Shortcut if you happen to have one, but it's probably not going to be very reliable.
IE7 Beta 2 always fetches the favicon but I don't know whether that's something that the WebBrowser control is doing, or whether it's the IE shell.
Stability. What an interesting concept. -- Chris Maunder

Hi all,
I'm reading 8 bytes from a byte array in order to create a double value. In order to do this I must fist read the bytes into an int64 then cast this to double. I'm having a little trouble shifting the array values into the correct position within the __int64.
__int64 *buf = new __int64;
*buf = (((((((data[6] | data[7] << 8) | data[8] << 16 ) | data[9] << 24 ) | data[10] << 32 ) | data[11] << 40 ) | data[12] << 48 ) | data[13] << 56 );
__int64 foo = ((data[10] | data[11] << 8) | data[12] << 16 ) | data[13] << 24;
__int64 bar = (((data[10] << 32) | data[11] << 40) | data[12] << 48 ) | data[13] << 56;
*foo <<= 32;
double* dub = (double *)buf;
double val = *dub;
As you can see from my code I am unable to read all 8 bytes in one line. The bytes only fill the first 32 bits. So when the values are read into *buf, the first 4 bytes goto the correct position then the next 4 bytes overwrite them. Why is this? If I read the first 4, then shift them 32 bits, then read the next 4 I can correctly read them. But why can't I read them in 1 line of code?

This expression returns 0 because an int is 32 bits. You need to make the left hand side a 64-bit int so the compiler knows you want a 64-bit result:
(__int64)data[10] << 32
Also you should be using unsiged __int64 - always use unsigned types when doing bit shifting.

Thanks for the reply, I understand your answer though I cannot understand why the compiler thinks it to be a 32 bit int. In all 3 of my examples the data type was create as a 64 bit int, int is never mentioned. So why should I have to cast the byte?

Because a byte left-shifed by anything more than 8 bits is zero. Just as a short shifted by anything more than 16 bits is zero.
The compiler only looks at one expression at a time, it doesn't know that it's ultimately going to assign to a 64-bit int. The promotion to __int64 doesn't happen until the entire right-hand side is evaluated, but by that time data has been lost.

Aaah, Gotcha. Thanks for the info.

Is there a reason you want it in one line?
A small loop can handle it with a lot more clarity and maintainability.

Hello all,
I have implemented an http server in which whenever the client requests a file, my server sends the file. My client is Windows Media Player and I generate the request from the "Open URL" option.
Now I want to implement that whenever client requests a file, the sever should send the same file continuously in a loop, and the client should play that file in a loop.
Can anybody help?
Regards,
Harshita

I have a project which when compiled by VC++ 2003 Pro produce a DLL of 145KB. When I compile this project in VC++ 2005 Std the DLL is 158KB.
Does this mean VC++ 2003 produces better code ?
BTW, the project in question is a Monkey's Audio input plugin for the QCD audio player (http://quinnware.com/bin/plugins/input/sup_QCDApeSrc.zip)

I have seen the same thing with regard to the size of the code produced, but unless you make the distinction that smaller code = better code, then you cannot say that the small stuff is better. There is probably more error handling and checks in the 2005 version as well as default settings could be different.

I have a class called Point. I am creating a class called Point3D that is inherited from Point. Point has private data members int xCoord, yCoord. Point also has functions called getX() and getY().
Point3D is inheriting from Point. Point 3D has a new datamember int zCoord. Point also has a function distanceFrom that looks like this:
double Point::distanceFrom(Point& p) { //distance between this point & p
return sqrt((xCoord - p.xCoord) * (xCoord - p.xCoord) +
(yCoord - p.yCoord) * (yCoord - p.yCoord));
}
Point's header file looks like this:
class Point{
public:
Point(); //default constructor
Point(double, double, string); //conversion constructor
double getX() const;
double getY() const;
string getName() const;
void setX(double);
void setY(double);
void setName(string);
double distanceFrom(Point&);
void printP();
private:
double xCoord, yCoord; //coordinates of the point
string name; //name of the point
};
so I am trying to overload the distanceFrom function to use the zCoord. Here is what I have:
double Point3D::distanceFrom(Point3D& p3D)
{
return sqrt((p3D.getX() - getX()) * (p3D.getX - getX()) +
(p3D.getY() - getY()) * (p3D.getY() - getY()) +
(p3D.zCoord - getZ()) * (p3D.zCoord - getZ()));
}
but i am getting these errors:
error C2475: 'Point::getX' : forming a pointer-to-member requires explicit use of the address-of operator ('&') and a qualified name
error C2475: 'Point::getX' : forming a pointer-to-member requires explicit use of the address-of operator ('&') and a qualified name
error C2296: '-' : illegal, left operand has type 'double (__thiscall Point::* )(void) const'
can anyone shed some light why i cannot do this? I just want to inherit the functions from Point (getX getY) to get x and y values. then get my z coordiate to get the distance.
Thank you,
Ed

Ed, does this work?

Thank you for the quick response, however, i get this...
error C2228: left of '.getX' must have class/struct/union type

Argh - I'm blind. The code has a typo. The compiler error is referring to getX when you probably I meant getX().

Thanks again for the quick response ravi.
I made the changes to :
double Point3D::distanceFrom(Point3D& p3D)
{
return sqrt((p3D.getX() - this.getX()) * (p3D.getX() - this.getX()) +
(p3D.getY() - getY()) * (p3D.getY() - getY()) +
(p3D.zCoord - getZ()) * (p3D.zCoord - getZ()));
}
I am still getting that error.
Funny, when i comment the first line out
double Point3D::distanceFrom(Point3D& p3D)
{
return sqrt(//(p3D.getX() - this.getX()) * (p3D.getX() - this.getX()) +
(p3D.getY() - getY()) * (p3D.getY() - getY()) +
(p3D.zCoord - getZ()) * (p3D.zCoord - getZ()));
}
it's a okay!
here are my declarations from my point class...
double Point::getX() const {
return xCoord;
}
double Point::getY() const {
return yCoord;
}

nevermind, i got it. thanks Ravi!

The third getX is missing the parentheses to make it a function call.
