Don't use fopen() or the other C runtime file functions from <stdio.h> for reading binary data. They're only designed for use with text files.
Under Windows, use CreateFile() to open a file and ReadFile() to read data from it. You can also use the _open() function and _read() to read from the file, which may be more portable (the POSIX binary functions are named open() and read()).

Where did you get this from? fopen(), fread(), fwrite(), and fclose() operate on both text files and binary files. They always have.

Don't you have to add a flag or something in order to read binary data?
Perhaps not with the fXXX() family... I don't have MSDN near my hands so I can't check if it is so.

Have you tried using any of the m-type symbols in the watch window?
I use these two quite often:
m
ma
I've never used these:
mb
mw
md
mq
mu

If you have access to CodeProject, you have access to MSDN[^]

True, but I don't waste any time and money of big loadings at MSDN online with my damn modem!

Why you don't use the Win32 API functions CreateFile, ReadFile, ... ?

I use this coed to read files:
FILE *file = fopen(szpath,"rb");
if(file!=NULL)
{
char *svRead;
fseek (file , 0 , SEEK_END);
long lSize = ftell (file);
rewind (file);
svRead = (char*) malloc (lSize);
int i = fread(svRead,sizeof(char),lSize,file);
}
But it works only for TEXT files ad when I read jpg files with it ,it only read 3 or 4 first character.

Hi,
I want to change the Winlogon policy programmatically. This I'm able to do by finding some of the registry entries in the Windows registry which would bring this policy into effect.
But changing this policy through registry don't show the changed status in the windows 2k Local Security Policy snap-in.
What shall I do to reflect this change in the Local Security Policy Snap-in.
Thanks,
Abhishek.

Does anyone know about a tool that can convert a .mak file to a .dsp file?
Wenn ist das Nunstück git und Slotermeyer? Ja! Beierhund das oder die Flipperwaldt gersput!
|
|
|
|

The tool is ............... Visual C++.  ;P;P
Run your Visual C++ ... the menu:
File -> Open Workspace ->
Choose the file type to open as Makefile (.mak) or All types (*.*)
......

Thats nice.....
OK I wasn't clear enough. I don't want just the .mak file inserted, I want a full .dsp file that contains all the same files as the .mak file so I can get class view, file view and resource view as I do with a regular project created in VC.

Hi
I can be wrong with this, but is the .mak file a textfile and can't you just rename the .mak to .dsp?
Hope it helps a bit.
Greetings
Jens

No no no no!
A .mak and .dsp file is NOT the same!
Open a mak file and a dsp file in Notepad and look.
