Hello.
You can change the file size as long as you have the file opened for writing, so "r+" (append) is OK.
The _fileno() function is in the runtime library, so you do have it, for sure. It's declared in stdio.h.
If it's missing, the try using fileno() instead.
Kakan.

Hi.
I'm building an MFC app, and at this time trying to add printing facilities.
What i need to do, is to print the image (all the windows of my app show different images) so that it fits the printing page...i've been trying to find the correct calculation (working on OnPrepareDC) with different page/window/screen measures (GetDeviceCaps(...)), but i don't seem to get it.
The pseudo code of OnPrepareDC:
<br />
SuperView::OnPrepareDC(pDC, pInfo);<br />
if (IsPrinting)<br />
{<br />
pDC->SetMapMode(MM_ANISOTROPIC);<br />
CClientDC dc( this );<br />
CSize szScreen = dc.GetDeviceCaps(...);<br />
pDC->SetWindowExt( szScreen );<br />
<br />
CSize szPage = pDC->GetDeviceCaps(...);<br />
CSize szfinal = SOME_CALCULATIONS(szScreen, szPage);<br />
pDC->SetViewportExt( szFinal );<br />
}<br />
...<br />
If someone understood the message, and knows something about it...will save my life.
Thanks,
Alberto

Do a search for RegOpenKey - you will likely find usable examples of how to use the registry-related functions.

Of the top of my head, can't think of a way in C, but in C++ you can simply use some form of static initialiser.
Be warned though, that they can cause problems if not handled correctly. I'd recommend asking yourself if you really need to do this?

Pls elaborate "Static initialiser ".
Small code can be of help.

1. Get yourself a sledge hammer
2. Take a deep breath
3. Swing the hammer back and give the program (The display, where it is being shown) a merciless blow.
4. The program should have crashed by now.
 This is a code sample
<br />
#include<iostream><br />
using namespace std;<br />
<br />
class GoGoGo<br />
{<br />
public:<br />
GoGoGo() <br />
{ <br />
cout << "This runs first!";<br />
} BeFirst;<br />
}<br />
<br />
int main()<br />
{<br />
cout << "Main is second :(";<br />
return 0;<br />
}<br />
Google for interview questions and u will find a lot of stuff. I learned this from google some months back.

You need to declare an instance of class GoGoGo before this will work - i.e.:
GoGoGo executesBeforeMain;
Kev

It has to be
class GoGoGo<br />
{<br />
public:<br />
GoGoGo()<br />
{<br />
cout << "This runs first!";<br />
}<br />
}BeFirst;
never say die

Sorry abt that. Din notice it.

int CrashingFunc();<br />
<br />
static int SomeIntThatCrashesTheProg = CrashingFunc();<br />
<br />
int CrashingFunc()<br />
{<br />
}
The static variables will be evaluated first and this will call your CrashingFunc before the main()
|
|
|
|
|
is it neccesary to put static .
static int SomeIntThatCrashesTheProg = CrashingFunc();<br />
<br />
int CrashingFunc()<br />
I feel int SomeIntThatCrashesTheProg has to be Global which u have defined with static
never say die

If so, you will do a never ending study. Atleast after you start with windows programming. (If you ever finish studying this with C and C++) 
Why do this dude? Destructive mind huh?
