• Please check the posted code (for instance use < to escape the symbol < when required).
• Why are you calling directly the timer function inside OnInitDialog (instead of starting the timer? You may actually do it, but usually you haven't...)?
• Since you're calling directly (form OnInitDialog) your timer function (OnBnClickedTimer) it doesn't make sense the OnStopTimer call in the latter.

try
{
   fstream file;
   vector<lpwin32_find_dataw> files;
   LPCTSTR namepointer;
   HANDLE handle;
   string line = "";
   int i = 0;
   int size;
   char directory [] = "C:\\Folder";
   char *stringpointer = directory ;
	
   files.assign(1, LPWIN32_FIND_DATAW());
   handle = FindFirstFile(namepointer, files[i]);
		
   while (handle != INVALID_HANDLE_VALUE)
   {
      FindNextFile(handle, files[i]);
      files.assign(1, LPWIN32_FIND_DATAW());
      i++;
   }	
   size = files.size();

   cout << files.size() << endl;
   for (int k = 0; k < size; k++)
   {
      cout << "Reading File:" << files[k]->cFileName << endl;
   }
   getchar();
   return 0;
}
catch (exception ex)
{
   cout << "An error has occurred." << endl;
   cout << ex.what() << endl;
}</lpwin32_find_dataw>

Why do you have a vector of WIN32_FIND_DATA structures? One is sufficient.

namepointer = stringpointer;

FindFirstFile and FindNextFile seemed to return only as single file, so I assumed LPWIN32_FIND_DATAW represented a single file.

vector<string> files;
WIN32_FIND_DATA findData;
BOOL bFound = TRUE;
 
HANDLE handle = FindFirstFile("C:\\*.*", &findData);		   
if (handle != INVALID_HANDLE_VALUE)
{
    while (bFound)
    {
        files.push_back(findData.cFileName);
        bFound = FindNextFile(handle, &findData);      
    }	   
}
 
for (int k = 0; k < files.size(); k++)   
    cout << "Reading File:" << files[k].c_str() << endl;

Thanks, though this code stil throws 2 errors.
