'unsigned short [260]' to 'char *' (Using Windows Mobile RAPI)

Hi, I am currently working on an app that talks to a PocketPC using RAPI. I am at VERY begginer level in C++ and am still working through types and pointers.

The code below connects to a Pocket PC and tries to retrieve a directory listing. My issue is with the "wfd.cFileName" which reports as bing a 'unsigned short [260]', I need it as a string/char to populate a list in a window.
-----------------------------------------------------------------------------------------------
HANDLE hFind;
CE_FIND_DATA wfd;
HRESULT hRapiResult;
wcscpy( wszDirectory , L"\\*");
hRapiResult = CeRapiInit();

if (FAILED(hRapiResult)) //Do something if connection failed

hFind = CeFindFirstFile( wszDirectory, &wfd);
if (INVALID_HANDLE_VALUE == hFind) // Do somthing as Directory does not exist    

do {

      if(wfd.dwFileAttributes & FILE_ATTRIBUTE_DIRECTORY)
            wfd.cFileName <-(This is what I need as a string)
      else          
      {
            wfd.cFileName <-(This is what I need as a string)
      }
} while ( CeFindNextFile( hFind, &wfd));
CeFindClose( hFind);
CeRapiUninit();
-----------------------------------------------------------------------------------------------
Thanks,

Pete.

cFileName  is WCHAR array .... use WideCharToMultiByte to convert from WCHAR to regular string

Could you give an example using the above code? Again as I mentioned my C++ skills are very basic.

Thanks.

try
char filename [256];
WideCharToMultiByte( CP_ACP, 0, (LPCWSTR) wfd.cFileName , -1, filename, 200, NULL, NULL );
