Hi

I am using ::MoveFile(sFrom, sTo) to move and re-name a file, which works ok but my problem is when the file is moved its Date Created is changed to the time it's moved. How can I move the file and keep the orginal creation date

Hi Dj_Fx8,

i'm not sure about a change in creation date (will check this), but maybe you are better of with the duo of
  CopyFile(org,new)
and
  DeleteFile(org)

Try SHFileOperation with FO_MOVE operation. This function is called by Windows Explorer. Explorer Move function doesn't change creation date.

Dj_Fx8,
yepp, CopyFile() modifies the date the same way MoveFile did, sorry.
AlexFM's comment sounds good (will try it now too :) )

Ok whats wrong with this, for every file it says Cannot move file: Cannot read from the source file or disk. but the files are there ok ???

      SHFILEOPSTRUCT  lpFileOp;
      lpFileOp.hwnd = pParent;
      lpFileOp.wFunc = FO_MOVE;
      lpFileOp.pFrom = sFrom;
      lpFileOp.pTo = sTo;
      lpFileOp.fFlags = FOF_RENAMEONCOLLISION | FOF_SILENT;
      lpFileOp.fAnyOperationsAborted = FALSE;
      lpFileOp.hNameMappings = NULL;
      lpFileOp.lpszProgressTitle = NULL;

      if (!SHFileOperation(&lpFileOp))
            return TRUE;

lpFileOp.pFrom = sFrom;

pFrom
Address of a buffer to specify one or more source file names. Although this member is declared as a null-terminated string, it is used as a buffer to hold multiple file names. Each file name must be terminated by a single NULL character. An additional NULL character must be appended to the end of the final name to indicate the end of pFrom.

So what your saying is I have to add NULL on to the end of sFrom, as sTo can also contain a list of files do I need to add a NULL to it as well. One other small point, how do I add NULL onto the end of a string?

Dj_Fx8,
adding a NULL char to the end of a string means you put the binary 0 (not the char '0') into the proper char array positon.
easiest thing would be to initialize any string with 0 after defining it.

char sT0[256];
memset(sTo, 0x00, 256);
after this you can fill your char array with the need file strings.

Well thats it working fine now, thanks guys for your help, I'll split the points, just as a closing comment I notice using  SHFileOperation  is considerably slower than ::MoveFile
