problem with fwrite

[CPallini]

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)?

thanks for your help, that's the worse thing I've ever met >.<

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

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

I've found my problem :D... 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.
