    Filenextfile

    Programming in visual c++. I got a editbox and a button on a form.
    when i press the button, the editbox gets filled with files and directorys.


    here is my code
    Code:
    HANDLE hFind;
    WIN32_FIND_DATA data;
    hFind = FindFirstFile("*.*", &data);
    if (hFind != INVALID_HANDLE_VALUE) {
     do 
     {
      
      
    GetDlgItem( testing )->SetWindowText( data.cFileName );
      
     }while(FindNextFile(hFind, &data));
      
    }

    1. You start with
    strcat(data,"\n");
    but what is data initialised to? Is it a large char array filled with \0, or just an uninitialised pointer?

    2. Consider various combinations of \n and \r to create a newline

    3. Consider calling SetWindowText() at the end (just once), when you've finished scanning the directory.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
    I support http://www.ukip.org/ as the first necessary step to a free Europe.
