Check Directory exists 2

[shetlandbob]

I'm try to detect if a directory exists, using

  if ( fopen ( "C:\\MyDir", "r" ) )
  {
    directoryFound = true
  }
  else 
  {
    directoryFound = false
  }

this code cant find my directory but if I use:

  if ( fopen ( "C:\\MyDir\\myfile.txt", "r" ) )
  {
    directoryFound = true
  }
  else 
  {
    directoryFound = false
  }

it finds it??? any ideas whats wrong with the first code?

fopen doesn't serve to open directories, it is only for files.

Use this function to test whether the directory exists:

BOOL existsFolder(const CString & folderName)
{
	WIN32_FIND_DATA data;
	HANDLE hFile = FindFirstFile(folderName, &data);

	if ( hFile == INVALID_HANDLE_VALUE ) // directory doesn't exist
		return FALSE;
	else 
	{
		// is it folder or file?
		FindClose(hFile);
		if (data.dwFileAttributes & FILE_ATTRIBUTE_DIRECTORY)
			return TRUE;
		return FALSE;
	}
}

Standa K.

you can also check out the simplest shell API extension function PathFileExists.

like this

#include <windows.h>
#include <shlwapi.h>
#pragma comment (lib, "shlwapi")

int main(int argc, char *argv[])
{
BOOL b = PathFileExists("C:\\Program Files");
return 0;
}

HTH,

Sweet Ionel! I was still using the StandaK way, which is tried and true. There are so many api calls and this one makes things much easier.

Thanks again

Thank you. You should check all the function from shlwapi.dll (look for PathFileExists in MSDN then click locate)

I am sure you will find many other useful functions like PathAddBackslash, PathStripToRoot etc.

See you,

Also you may use GetFileAttrigutes("path") == -1 then file does not exist
