Console tab stops?

[brew]

How would I fix the shwiconEM.exe and vmnetdhcp.exe lines' disalignment? I figure I can do it by setting my own tab stops, but how? The output looks so messy. Right now I'm using two \t's.

It ain't dynamic.  Get over it.

The best way is probably to use printf()-style formatting parameters (you can do it in C++ too, but I don't know how)

printf("%32s %d\n");

That'll print the string in a 32-character column. I forget whether it aligns the string left or right, but you can probably play around with it and get it right.

The other option is to manually do it:
int i;
printf("%s", str);
for(i = 0; i < 32 - strlen(str); i++)
  printf(" ");
printf("\n");

There's probably a better way to do that, but whatever.

You were right-- it alligns to the right, i wonder how i would get it to the left? (actually i dont think i can :/) So yeah, padding it with spaces for every char it doesn't take up is the best idea. Thanks for helping.

C# was the last language I remember you to brown-nose. If not, port it yourself.

Code Select Expand

using System;
using System.Collections.Generic;
using System.Text;

namespace StringPadding
{
    class Program
    {
        static void Main(string[] args)
        {
            Console.WriteLine("String padder");
            Console.WriteLine("A Joe[x86] Production!");
            Console.WriteLine();
            Console.WriteLine(padStringRight("Brew is an idiot.", 'x', 32));
            Console.WriteLine();
            Console.WriteLine("Press any key to exit.");
            Console.ReadKey();
        }

        private static string padStringRight(string data, char padding, int length)
        {
            if (data.Length > length)
                throw new ArgumentOutOfRangeException("length", "length parameter is shorter than data's length.");

            char[] ret = new char[length];
            Array.Copy(data.ToCharArray(), ret, data.Length);
            for (int i = data.Length; i < length; i++)
            {
                ret[i] = padding;
            }
            return new String(ret);
        }

    }
}

What? I can't port that, I don't know C# at all. I never coded in C# or anything .NET for that matter, and I intend to never code in any .NET languages in my lifetime. And if you had read my last post you would have found that I've already got it figured out-- I just used a space padder like iago said to. I first learned about a space padder long ago, back when I was making columns for a listbox control in vb. I just never thought of using it for this (i figured sprintf would have something i didn't know about that does this, apparently not)

Also, nice coding practice:

return new String(ret);

Allocating heap memory for a string? And you don't even free it in main(). So what if the program is going to end and it wouldn't matter, it's just not a good idea to do that IMO.

C# is a garbage collected language.  All classes are allocated using the new keyword, and are disposed of automatically when they are no longer referenced.

The best way is probably to use printf()-style formatting parameters (you can do it in C++ too, but I don't know how)

In C++ you use the stream operators found in the <iomanip> header.  In this case, probably something like:

using namespace std;
cout << setw(32) << left << "foo" << setw(32) << left << "bar" << endl;

You were right-- it alligns to the right, i wonder how i would get it to the left? (actually i dont think i can :/) So yeah, padding it with spaces for every char it doesn't take up is the best idea. Thanks for helping.

I'm pretty sure I was talking to iago
@K: I don't want to use any C++. I , personally, hate classes or anything OO of that sort.

To align to the left I believe you specify a negative padding number:

printf("%-32s", s);

Joe, first of all that's not the right approach, and even if it was, C# already has String.PadLeft and String.PadRight methods that work on the instances of the strings they're changing.

The proper way to do it would be to use formatting strings.  Format strings allow an alignment property to be set:

Code Select Expand


using System;
using System.Diagnostics;
using System.IO;
using System.ComponentModel;

class Program
{
    static void Main(string[] args)
    {
        Console.WriteLine();
        Console.WriteLine("            ===={ Process Viewer }====");
        Console.WriteLine();
        Console.WriteLine("  {0,24}{1,10}", "Image Name", "  ID ");
        Console.WriteLine();
        Process[] processes = Process.GetProcesses();
        int threads = 0;
        foreach (Process p in processes)
        {
            try
            {
                Console.WriteLine("  {0,24}{1,10}", Path.GetFileName(p.MainModule.FileName), p.Id);
            }
            catch (Win32Exception)
            {
                Console.WriteLine("  {0,23}*{1,10}", p.ProcessName, p.Id);
            }
            threads += p.Threads.Count;
        }

        Console.WriteLine();
        Console.WriteLine("  Total number of processes: {0}", processes.Length);
        Console.WriteLine("  Total number of threads: {0}", threads);

        Console.ReadLine();
    }
}


Note: for processes that do not expose a main module (I was receiving ACCESS_DENIED errors), I have marked them with a * at the end of the process name.

Result:


K: that (left alignment) is likely correct.  .NET's formatting was based on C, and that's how you would left-align.

[brew]

To align to the left I believe you specify a negative padding number:

printf("%-32s", s);

Oh wow, that's just what i was looking for.
Mynd, I've noticed that people call blank writelines in order to space their lines out. Is there no '\n' in C# or something? That'd be pretty sad if there weren't

[iago]

"\n" isn't a standard. Windows, for example, uses \r\n. Linux uses \n. iirc, Mac uses \r. So using println() guarantees, in a platform-independent way, that you'll get the proper newline character.

That may seem silly in C#, which is only typically run on Windows, but it's still a good habit. Plus, people might make silly mistakes like using "\n" instead of "\r\n"
