I would like to ask, how to get a file exists, not using FileExists

hardnature

Ask you prawn:
 How to find out if a file exists or not with FileExists, is there any other function?

mystonelh

// Give you a custom function to get whether the specified file exists
bool FileExist (LPCTSTR szFindPath)
{
int count = 0;
int i = 0;
WIN32_FIND_DATA fd;
HANDLE hFind;
if (strlen ((char *) szFindPath) <= 0)
return false;
char path [257];
    char * pPath;
    pPath = path;
    count = strlen (szFindPath);
if (count <= 0)
return false;
    

// Get the path string from front to back
for (i = 0; i <count; i ++)
{
        if (* (szFindPath + i) == '\\')
break;
* (pPath + i) = * (szFindPath + i);
}

   * (pPath + i) = '\\';
   * (pPath + i + 1) = '\0';
    hFind = FindFirstFile (szFindPath,&fd);

if (hFind! = INVALID_HANDLE_VALUE)
{
FindClose (hFind);
}

return hFind! = INVALID_HANDLE_VALUE;
}

(access (filename, F_OK)) == 0)

Find by example, compare with the desired file name
CFileFind ff;
strPltfind = "*. *";
BOOL res = ff.FindFile (strPltfind);
while (res)
{
res = ff.FindNextFile ();
filename = ff.GetFilePath ();
// ----- Open and store file data ---------------------
// You can store filename
         if (! filename.Compare ("/ * file name to find * /"))
         {
         ..................
         }
}
for reference only:_)

CString strTmp = "full file path";
CFileFind FileFind;
BOOL br = FileFind .FindFile (strTmp);
if (br)
{
  //presence
}
else
{
  //does not exist
}

That's so troublesome, just use pathfileexists ("c:\\a.txt"); to judge

#include <io.h>

...
if (_access ("c:\\path.ext", 0)! = -1)
    // File exists
