Too lazy to read the RFC eh?

I can't blame him, I looked up the HTTP RFC and it took forever to download on my High-Speed Broadband
Sorry I couldn't help but emphasize the high-speed part

Not really!
The protocol's pretty straightforward. Instead of sending a "GET" (to download a resource), I send "HEAD". When I read the response, it will contain the header information sent by the HTTP server. My problem is, I'm trying to figure out the Internet_mumble calls to make.

Try with an ISAPI extension. You can send HTTP headers and read resoponses very easily. Search MSDN for CHttpServer and CHttpServerContext classes.

Actually, I want to do this on the client side.

Has anybody been able to pull this off?
I am able to get a tooltip to work over the edit box portion, but
when the dropdown is active, I can't capture mousemoves over the dropdown
or get tooltips to show up no matter what I do! 
Please advise if you can
Thanks

I have a function that taken a variable argument list. I wanted to just forward those arguments to another function that also takes a variable argument list.
Example:
void f2(const char* string, ...);
void f1(const char* string, ...)
{
... (prepend something to string, call it string2)
f2(string2, ?); //what goes in ?
}
What needs to be done to make this work?
Thanks

It can be done in a wildly non-portable fashion just like this (some details may need more careful handling for this to actually work): the variable argument list is stored in the stack and its beginning can be accessed with the macro va_start. So one can just copy a large enough portion of the stack and transfer it to f2. The scheme is as follows:
struct stack_chunk
{
char memory[1024];
};
void f1(const char *string,...)
{
stack_chunk chunk;
va_list v;
va_start(v,string);
memcpy(&chunk,v,sizeof(chunk));
va_end(v);
...
f2(string2,chunk);
}Please tell us it this worked.

You can have a look at the wvsprintf function.

Hello all, I was wondering if someone could help me with this little problem.
I have the class constructor where I initialize protected member m_categoria (LPCTSTR):
CAdministrador::CAdministrador()
{
char buffer[_MAX_PATH];
_getcwd( buffer, _MAX_PATH );
CString nom = "";
nom = nom + buffer + "\\General";
m_categoria = nom;
AfxMessageBox(m_categoria);
}
The value comes out Ok in the message box; but then I try to look at the value in another function and I get crap:
BOOL CAdministrador::AgregarCategoria(LPCTSTR nombre)
{
AfxMessageBox(categoria);
CString nom = "";
nom = nom + m_categoria + "\\" + nombre;
if (_mkdir(nom) == 0)
return TRUE;
else
return FALSE;
}
The call is simply this:
CAdministrador admin;
if (!admin.AgregarCategoria("blah"))
AfxMessageBox("didn't work...");
Please excuse me if this question is extremely dumb

Hola Marcela!
When you write
m_categoria = nom; you're accessing the internal representation (as a LPCTSTR) of the CString nom. m_categoria will be OK as long as these two conditions hold:nom is not modified.nom is not destroyed.
The latter is precisely what's happening when the constructor exits, so m_categoria will basically point to some junk area in the heap from now on. Best way to handle this is declaring m_categoria as a CString itself, so that it keeps and manages its own memory.

I have a dialog window application, and i need to know how to add tool tip text to a button. Can someone please help me with this one. PLEASE!!!!! I do not want to have to use someone's pre built classes either.

Look at the buttons section here at CodePeoject. Davide Calabro's CButtonST v3.4 (MFC Flat buttons) seems a popular one, and includes a lot of additional goodies.

You need to override the PreTranslateMessage member function of your CDialog class and call the CMyToolTipCtrl.RelayEvent

Argh....
I have code that looks like this:
in "ObjectCache.h":
template <class T>
class CObjectCache {
...
};
in "App.h":
#include "ObjectCache.h"
#include "DataObject.h"
class CApp {
CObjectCache<CDataObject> m_Cache;
...
};
Can anyone think of any reason why the compiler would be yacking on the m_Cache line? It's telling my that "m_Cache uses undefined class 'CObjectCache<class CDataObject>'
But as far as I can see, the class is defined - everything is defined in ObjectCache.h and it's included. And everything for the contained class CDataObject is defined in DataObject.h that's included.
I've transplanted this code into a plain application, and it works fine. In my MFC application, it's crapping out.
Any ideas at all?

Maybe it's the precompiled headers feature playing tricks again. Make sure your first #include in every .cpp is stdafx.h. If this doesn't work, try a "Rebuild all" as a last resort.

Done.

Doesn't fix it. 
I'm quite stumped. I've even dug through the preprocessor output (/E option) and my template is defined nicely (and so is the contained class).
ARrrrrgh.
