I''ve been looking for the solution to this question for a while now, but I can''t find a reference to it in my C++ book or anywhere on the internet. I need to get a list of the files in a directory, and then randomly choose one. But how do you get a directory listing in C++? I can''t find any way to do it. Help please. Thanks

I don''t have a compiler at hand, so this may not compile. This will get a list of files in a directory, as far as picking a random one there is more than one way to do that. I would copy the results to a list, and just pick a random one.


WIN32_FIND_DATA fdFind;
HANDLE hFind;
bool bContinue;

hFind = ::FindFirstFile("c:\\somedir\\*.*", &fdFind);

bContinue = (hFind != INVALID_HANDLE_VALUE);

while(bContinue)
{
    //This will just output the file names to the output window.
    ::OutputDebugString(fdFind.cFileName);
    ::OutputDebugString("\n");

    bContinue = (bool)::FindNextFile(hFind, &fdFind);
}

if(hFind != INVALID_HANDLE_VALUE)
    ::FindClose(hFind);

Thanks cybrgeek... that code works perfectly. Just a small adjustment needed to work with my logging functions to check the output.

I''m sure I can work with this to do what I need now.
