File Isn't Deleting - windows

Question

I have a code that finds files that are less than 20 seconds old. It's finding them, but I can't get them deleted. I am using remove(). I've tried using remove with wildcards but no luck. It has to be something with the syntax. Any help is appreciated. Thank you.
using namespace std;
typedef vector<WIN32_FIND_DATA> tFoundFilesVector;
std::wstring LastWriteTime;
int getFileList(const char * filespec, tFoundFilesVector &foundFiles)
{
WIN32_FIND_DATA findData;
HANDLE h;
int validResult=true;
int numFoundFiles = 0;
h = FindFirstFile((LPCSTR)filespec, &findData);
if (h == INVALID_HANDLE_VALUE)
return 0;
while (validResult)
{
numFoundFiles++;
foundFiles.push_back(findData);
validResult = FindNextFile(h, &findData);
}
return numFoundFiles;
}
void showFileAge(tFoundFilesVector &fileList)
{
unsigned _int64 fileTime, curTime, age;
tFoundFilesVector::iterator iter;
FILETIME ftNow;
CoFileTimeNow(&ftNow);
curTime = ((_int64) ftNow.dwHighDateTime << 32) + ftNow.dwLowDateTime;
for (iter=fileList.begin(); iter<fileList.end(); iter++)
{
fileTime = ((_int64)iter->ftLastWriteTime.dwHighDateTime << 32) + iter- >ftLastWriteTime.dwLowDateTime;
age = curTime - fileTime;
if (age <= (_int64)200000000UL)
{
wcout << " Delete: '" <<endl;
wcout << "FILE: '" << iter->cFileName << "', AGE: " << (_int64)age/10000000UL << " seconds" << endl;
remove("C:\\mapper\\iter->cFileName");
}
else
{
//wcout << " Quit: '" <<endl;
//return;
}
}
}
int main()
{
string fileSpec = "*.*";
tFoundFilesVector foundFiles;
tFoundFilesVector::iterator iter;
int foundCount = 0;
getFileList("c:\\Mapper\\*.txt", foundFiles);
getFileList("c:\\Mapper\\*.jpg", foundFiles);
foundCount = foundFiles.size();
if (foundCount)
{
wcout << "Found "<<foundCount<<" matching files.\n";
showFileAge(foundFiles);
}
system("pause");
return 0;
}

You need to concatenate the strings "C:\mapper\" with whatever is in iter->cFileName. The most simple way of doing that would be to use the std::string class.
The result would look something like this:
remove(string("c:\\mapper\\").append(string(iter->cFileName)).c_str());
This assumes you do not use unicode encoding of your strings, otherwise you need to use std::wstring. To use these classes you will also need to include
#include <string>
in the top of your file.
