Aside from finding a file, are you familar with sending/receiving data through a socket? If not, perhaps a scan through some of the articles here will get you started.

Didn't your first post state that "I am making a program...to view the files from a remote computer. and I have succeded in doing this?" If you are finding remote files and can send data via sockets, what's the issue(s)?

far -near pointer do they exist in our world

i was under the notion that far pointer or near for that matter had faded into oblivion with the arrival of FLAT MEMORY windows 9x.
but recently while going through some source code namely winsock.h and winsock2.h i saw it had plenty of far pointers . gethostbyname() for example returns a far pointer to a struct.At the same time msdn tells that far pointers are obsolete. PLEASE comment

if u cant hack it race it or take it to bed then it aint worth having

You'll notice that the preprocessor resolves FAR to far and then resolves that to nothing. It is simply there for backward compatibility.

hi david

u said FAR gets resolved to far and far into nothing
and this is for backward compactibility.

i tried using far pointers and got this error (VC++)

#include <stdio.h>
int main(void)
{

char far * a;
char s;
a =&s;
printf("%p\n",a);

}

error C4226: nonstandard extension used : 'far' is an obsolete keyword
if FAR is used instead there is no problem. i included windows.h

if far is obsolete keyword the how is FAR handled
windef.h does something like this
# define FAR far

so hows the resolution done

if u cant hack it race it or take it to bed then it aint worth having

You must've missed this statement a little earlier on in the same file:

#define far

Far and far are there for backward compatibility as Winsock.h is used for 16 bit and Winsock2 for both.
If you open windef.h you can look for the definition of FAR

Webbrowser Control: How do I implement my own "Save Image As ..."?

I implemented my own IID_IDocHostUIHandler because I needed my own ShowContextMenu method for my own context menu. By doing this I can recognize, if the user clicked on a link, text, image etc. and enable/disable several menuitems depending on the type of object I clicked on.
Now I want to implement my own "Save image as ..." method, but I have no clue how to get a reference to the picture I rightclicked.
Is there anybody out there who can help me? I searched with Google and the MSDN, but did not find anything.

Thanks a lot!

I need a software like the following:

This software can detect the other program running, it searches the system memory periodically.
Each program is stored on disk before running.
Each program has its own specific code on disk.
After it is loaded into memory and running by windows, this process memory has some specific code.
So, I need a software that can get the specific code on disk before running, and can scan the system memory and check the specific code in memory, and get this program HANDLE, and can terminate it.

How to do this thing.

Can somebody give me some advice. Thank you.
