Why does VC++ 2005 produce much larger EXE's than VC++ 2003 or VC++ 6.0 ?

For example, using the example project WTL for MFC part 1 (http://www.codeproject.com/wtl/wtl4mfc1.asp[^])

Smallest Release EXE I could get for VC++ 2005 was about 55KB compared to 28KB for VC++ 2003 and 34.5KB for VC++ 6.0.

What's the reason for it ?

My guess is extra security features build into the CRT library. That requires more code, so you get larger binaries.
If VC8 still supports the linker switch /opt:nowin98 don't forget to add that, as it will usually reduce the binary's size a bit.

Is there any way to remove these extra security features since it does seem to add a hefty chunk extra onto each compiled app ?

Or would it be OK to use the CRT library from VC++ 2003 ?

If so, which file(s) should I replace ?

Hi,
I tried to search for this in MSDN, but was unsuccessful after 30 minutes of trying....

Does anyone know how to access a file's Properties - like when you Right Click a .TXT file, and then click the Summary tab....

I want to programmatically put my own info in the Summary fields for:

1) Title
2) Author
3) Comments

... and do it all from my VC++ (MFC) code.

Thanks,
Johnny

That's "compound document" information. See here.

Thanks! I want to stuff info into these fields that I would otherwise have to extract in the "data" files I create. With these props set, I can just "mouse-over" a file listing in (File) Explorer and get a quick summary.

strange c code

I saw such c codes:

struct A {
...
}

int fun(long x)
{
...
A z=(struct A *)&fun;
...
}

How to explain that? can anybody help?
Thanks!

Declare a variable z of type A which takes the value of the address of the function fun.

It could be code which accesses the machine code of the function fun at runtime. What was the contents of the structure?

The struct is just as following:

int x;
Struct *Node;
}

I want to send the values in this array using CSocket.
Then use StretchDIBits API.

Not sure about Win CE (I'm guessing PPC means pocket PC) but in regular Win32 you can handle the WM_APPCOMMAND message. The OS sends that to the active app when the user presses one of the additional keyboard keys or mouse buttons.
