C++ File properties
-
Does anyone know how to access a file's properties in C++? For example, I need to get the time stamp off of some files in my program. (Any other properties would be helpful for me in the future as well.) Danny
Try
GetFileAttributesEx().

no, you don't need to include any other header. They are all already in the standard platform win32 sdk. ... she said you are the perfect stranger she said baby let's keep it like this... Tunnel of Love, Dire Straits.

When using, for example, GetFileTime, MSDN says I need to get a handle to the file by opening it with GENERIC_READ only. I tried both fstream.open() and fopen() ways of opening the file, both with read only selected. It doesn't seem to work (The call to GetFileTime always fails). How am I to get GetFileTime() to work?

You need to open the file with the
CreateFileWin32 function and it will return a handle to use with the other functions. Don't intermix the different stream, FILE*, etc. families of file function calls together. -
