Greetings!

So, I have this foreach loop which is moving a bunch of files over to another directory. I would like to use the ProgressBar to let the user know how long the process still needs to go through. I don-t want to do a Timer count, but a file count progress. I have never used ProgressBar and I have seen and compiled the progress.d example, but I don-t know how to transfer the code to use count instead of time. So, the foreach looks like this:

Code:

      char[][] allfiles = std.file.listdir(fromDir,"*");
      foreach(char[] f; allfiles)
      {
        char[] ffile = toDir[0 .. 1] ~ f[1 .. $];
        char[] fdir = std.path.getDirName(f);
        char[] tdir = std.path.getDirName(ffile);
        CreateDirectory(tdir);
        try
        {
          info.text = "moving " ~ f;
          std.file.rename(f,ffile);
        }
        catch (FileException e)
        {
          error.text = "Error moving file: " ~ e.toString();
        }
      }

So, what I would like to happen is that for every file that I move, it moves the progressbar. I have tried a few things, but I can not seem to find it.

Any help would be greatly appreciated.

thanks,

jose

Set the ProgressBar's maximum property to something like the total bytes of all the files or the number of files, and increase the value by the number of bytes processed or the number of files done so far.

Thanks. I just didn-t understand the whole thing... Here is the code which works:
Code:

      char[][] allfiles = std.file.listdir(fromDir,"*");
      pBar.minimum = 0;
      pBar.maximum = allfiles.length - 1;
      pBar.step = 1;
      foreach(char[] f; allfiles)
      {
        char[] ffile = toDir[0 .. 1] ~ f[1 .. $];
        char[] fdir = std.path.getDirName(f);
        char[] tdir = std.path.getDirName(ffile);
        CreateDirectory(tdir);
        try
        {
          info.text = "moving " ~ f;
          std.file.rename(f,ffile);
        }
        catch (FileException e)
        {
          error.text = "Error moving file: " ~ e.toString();
        }
        pBar.performStep();
      }
      pBar.value = 0;



Thanks.
