Question

I’m trying to get FindFileFirst() windows API call to work and it’s totally failing on every attempt. I’ve tried ., C:\*.*, .txt, C:\.txt and yet it doesn’t even iterate down directory names. Not sure what to try anymore. I’m getting ERROR_FILE_NOT_FOUND 2 (0x2) back when I call GetLastError(). Thanks for any help you can give.

HANDLE hFind;
LPWIN32_FIND_DATA FindFileData;

hFind = FindFirstFile("*.*", &FindFileData);

if(hFind == INVALID_HANDLE_VALUE)
{
    printf("\nFindFirstFile failed (%u)\n",GetLastError());
    return;
}

do
{
    if(FindFileData->dwFileAttributes & FILE_ATTRIBUTE_DIRECTORY)
    {
        if(FindFileData->cFileName[0] != '.')
            continue;
        else
            searchDir(makePath(path, FindFileData->cFileName));
    }

    printf("Found %s %s\n",
        FindFileData->dwFileAttributes,FindFileData->cFileName);
    FindClose(hFind);
}
while(FindNextFile(hFind, &FindFileData));

FindClose(hFind);

LPWIN32_FIND_DATA FindFileData;

You are using FindFileData pointer without allocating memory to it.

use this way.. (“remove LP”)

WIN32_FIND_DATA FindFileData; // this will use stack memory

then refer to members like FindFileData.dwFileAttributes instead of FindFileData->dwFileAttributes
