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if far is obsolete keyword the how is FAR handled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!

Use SendMessage API function with the WM_COPYDATA message

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.

I am writting by myself now. I can get all of the running process's HANDLE, and I can get all of each process's memory, but I don't know the relationship between specific code on disk and memory.

Can somebody give me some advice. Thank you.

I am studing the PE format. Hope somebody give some advice.

About what? In other words, what specifically do you want to know about the PE format?

MSDN and the Platform SDK are probably the best resources for TAPI documentation and examples.

Nice discussion point ?

-> this stood in the code:
bool bAllowUnvalidateTextResult = !!siteFlags.GetNbrValue(ALLOW_UNVALIDATE_TEXTRESULT);

Colleagues told me the "!!" was to make sure it was 0 or 1 false or true.
Is this so? Why not
static_cast<bool>(siteFlags.GetNbrValue(ALLOW_UNVALIDATE_TEXTRESULT)); ???

tnx.

The !! has been around for a while, long before these new fangled
template thingies. Its also less typing!

Also consider:

bool bAllowUnvalidateTextResult = 1 && siteFlags.GetNbrValue(ALLOW_UNVALIDATE_TEXTRESULT);

bool bAllowUnvalidateTextResult = siteFlags.GetNbrValue(ALLOW_UNVALIDATE_TEXTRESULT) ? true : false;

I still use the ? : construction a lot.

A couple of years ago, I showed some of my code to a fellow (non-colleague) programmer, who said
"It's obvious you've been programming for a long time". He never told me if that was a compliment
or not!
