Config the GuestOS's resolution in the VMware

To automatically fit the host os's resolution at full screen mode: the vxm file to add the entries: svga.maxWidth = "1280" svga.maxHeight = "800"

Sorting maps in Java based on it’s values

public class MapValueSort {

/** inner class to do soring of the map **/
private static class ValueComparer implements Comparator {
private Map  _data = null;
public ValueComparer (Map data){
super();
_data = data;
}

    public int compare(Object o1, Object o2) {
     String e1 = (String) _data.get(o1);
        String e2 = (String) _data.get(o2);
        return e1.compareTo(e2);
    }
}

public static void main(String[] args){

Map unsortedData = new HashMap();
unsortedData.put("2", "DEF");
unsortedData.put("1", "ABC");
unsortedData.put("4", "ZXY");
unsortedData.put("3", "BCD");

SortedMap sortedData = new TreeMap(new MapValueSort.ValueComparer(unsortedData));

printMap(unsortedData);

sortedData.putAll(unsortedData);
System.out.println();
printMap(sortedData);
}

private static void printMap(Map data) {
for (Iterator iter = data.keySet().iterator(); iter.hasNext();) {
String key = (String) iter.next();
System.out.println("Value/key:"+data.get(key)+"/"+key);
}
}

}

This should output something of the lines of:

Value/key:BCD/3
Value/key:DEF/2
Value/key:ZXY/4
Value/key:ABC/1

Value/key:ABC/1
Value/key:BCD/3
Value/key:DEF/2
Value/key:ZXY/4

Where the bottom last four lines obviously is sorted on the map’s values and not it’s keys.

jQuery Floating Layer Plugin

It can fix one layer(div) at the fixed position on the page.

C# 中的Map: Dictionary 的使用

We can use the statement, DicObj[keyObj] = valObject, to set/get the value corresponding to the key.

using System;
using System.Collections.Generic;

public class Example
{
public static void Main()
{
  // Create a new dictionary of strings, with string keys.
  //
  Dictionary<string, string> openWith =
      new Dictionary<string, string>();

  // Add some elements to the dictionary. There are no 
  // duplicate keys, but some of the values are duplicates.
  openWith.Add("txt", "notepad.exe");
  openWith.Add("bmp", "paint.exe");
  openWith.Add("dib", "paint.exe");
  openWith.Add("rtf", "wordpad.exe");

  // The Add method throws an exception if the new key is 
  // already in the dictionary.
  try
  {
      openWith.Add("txt", "winword.exe");
  }
  catch (ArgumentException)
  {
      Console.WriteLine("An element with Key = \"txt\" already exists.");
  }

  // The Item property is another name for the indexer, so you 
  // can omit its name when accessing elements. 
  Console.WriteLine("For key = \"rtf\", value = {0}.",
      openWith["rtf"]);

  // The indexer can be used to change the value associated
  // with a key.
  openWith["rtf"] = "winword.exe";
  Console.WriteLine("For key = \"rtf\", value = {0}.",
      openWith["rtf"]);

  // If a key does not exist, setting the indexer for that key
  // adds a new key/value pair.
  openWith["doc"] = "winword.exe";

  // The indexer throws an exception if the requested key is
  // not in the dictionary.
  try
  {
      Console.WriteLine("For key = \"tif\", value = {0}.",
          openWith["tif"]);
  }
  catch (KeyNotFoundException)
  {
      Console.WriteLine("Key = \"tif\" is not found.");
  }

  // When a program often has to try keys that turn out not to
  // be in the dictionary, TryGetValue can be a more efficient 
  // way to retrieve values.
  string value = "";
  if (openWith.TryGetValue("tif", out value))
  {
      Console.WriteLine("For key = \"tif\", value = {0}.", value);
  }
  else
  {
      Console.WriteLine("Key = \"tif\" is not found.");
  }

  // ContainsKey can be used to test keys before inserting 
  // them.
  if (!openWith.ContainsKey("ht"))
  {
      openWith.Add("ht", "hypertrm.exe");
      Console.WriteLine("Value added for key = \"ht\": {0}",
          openWith["ht"]);
  }

  // When you use foreach to enumerate dictionary elements,
  // the elements are retrieved as KeyValuePair objects.
  Console.WriteLine();
  foreach( KeyValuePair<string, string> kvp in openWith )
  {
      Console.WriteLine("Key = {0}, Value = {1}",
          kvp.Key, kvp.Value);
  }

  // To get the values alone, use the Values property.
  Dictionary<string, string>.ValueCollection valueColl =
      openWith.Values;

  // The elements of the ValueCollection are strongly typed
  // with the type that was specified for dictionary values.
  Console.WriteLine();
  foreach( string s in valueColl )
  {
      Console.WriteLine("Value = {0}", s);
  }

  // To get the keys alone, use the Keys property.
  Dictionary<string, string>.KeyCollection keyColl =
      openWith.Keys;

  // The elements of the KeyCollection are strongly typed
  // with the type that was specified for dictionary keys.
  Console.WriteLine();
  foreach( string s in keyColl )
  {
      Console.WriteLine("Key = {0}", s);
  }

  // Use the Remove method to remove a key/value pair.
  Console.WriteLine("\nRemove(\"doc\")");
  openWith.Remove("doc");

  if (!openWith.ContainsKey("doc"))
  {
      Console.WriteLine("Key \"doc\" is not found.");
  }
}
}

/* This code example produces the following output:

An element with Key = "txt" already exists.
For key = "rtf", value = wordpad.exe.
For key = "rtf", value = winword.exe.
Key = "tif" is not found.
Key = "tif" is not found.
Value added for key = "ht": hypertrm.exe

Key = txt, Value = notepad.exe
Key = bmp, Value = paint.exe
Key = dib, Value = paint.exe
Key = rtf, Value = winword.exe
Key = doc, Value = winword.exe
Key = ht, Value = hypertrm.exe

Value = notepad.exe
Value = paint.exe
Value = paint.exe

Value = winword.exe
Value = hypertrm.exe

Barcode Image Generation Library

It's the best solution without font supporting and free. Using the ashx, we can take various methods to generate / draw the barcode bitmap. In this library, barcode is drawed as thin line. In the other library, Code39, barcode is drawed as a little fat hence it's blurred while we print it out.
