as you can see in the code, I closed it, and before closed it, I fflush( fout ) carefully 
|

Yes, I saw the code, anyway I was referring to you debugging actions (i.e. I didn't know if you stopped the program after few write operations).
The reason behind my questions is I cannot believe fwrite silently failing, it never happened to me.
Can't you isolate the failing piece of the writing routine and run it in a simpler context (for instance another, adhoc, project)?
If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

Are you using a relative path?
What is the value of temp?

temp is the number of hotkeys, its value is the size of the vector contain my HOTKEY struct

I know what it represents. I asked what its value was (at the time of writing to the file).

I tried a simple example, its value at that time is 1

Ok, what do the two subsequent calls to fwrite() return?

I just watch the file pointer, it increase the value equal to the size I've requested to write on file

I've found my problem ... It happened when I ust CFileDialog in another code, select a path, then the default directory change too => write file at another place => can't read. Thanks for your help

Which is why I was asking if fopen() was failing.

i think i cannot explain more clear than that.
function parameters are not same.
CHYGO wrote: how to solve it?
it depends on your need, may be,
struct nids_prm
{
...
void (*syslog) (int,int,struct ip_header *,void *);
...
}; matches your need.
BTW, a basic C programing book can also solve.

thx, i need another mothes
i'll try it

Short answer: this way
struct nids_prm
{
...
void (*syslog) (int , int , struct ip_header *, void *);
...
};
Long answer: use variable number of argument for your functions (and modify accordigly syslog declaration).

thank u

In nids_prm struct, replace void (*syslog) (); with this: void ( *syslog ) ( int , int , struct ip_header * , void * );
When you declare a function pointer, you have to define exactly the parameters of that function ^^. Enjoy yourself ^^

i've tried ,and the error is the same

that's pretty clear, no ?
you're passing parameters to a function which requires none !
|
|

|

i don't know what's the problem is -_-!
when i drag the .c file into the VC6, the build the default project,then compile ,nothing happen
but when i build a WIN32 or MFC application , the error occur...
|
|
|
|
|
When you build the single .c file, VC6 treats the code as valid C.
The WIN32/MFC app is probably treating the code as C++, which in this case is invalid.

There are two possible solutions available to you:
1)
void (*syslog)(int, int, ip_header*, void*); 2)
static void my_nids_syslog()

error LNK2019: unresolved external symbol _LoadIFilter@12 referenced in function "bool __cdecl CreateIFilter(char *)" (?CreateIFilter@@YA_NPAD@Z)
Here is the code that I wrote:
#include <stdio.h>
#include <windows.h>
#include <locale.h>
#include <filter.h>
#include <filterr.h>
#include <ntquery.h>
bool CreateIFilter(const WCHAR *wcsPath)
{
IFilter *pIFilter = NULL;
HRESULT hr = LoadIFilter(wcsPath, NULL, (void**)&pIFilter);
if (SUCCEEDED(hr))
return true;
else
return false;
}
void DumpProps(char *filename) {
// Translate filename to Unicode.
WCHAR wcFilename[1024];
setlocale( LC_ALL, "" );
int i = mbstowcs(wcFilename, filename, strlen(filename));
setlocale( LC_ALL, "C" );
wcFilename[i] = 0;
if(CreateIFilter(wcFilename))
printf("Ok");
else
printf("False");
}
|
|
|
|
|
definition of the function is missing, easy way is to go to the documentation page of [LoadIFilter^] and check the Requirements section it specifies which library to link, "Import Library: Use ntquery.lib."
