How to make webpage with javascript load faster in html?

Web page load time is directly related to your web traffic. Your visitors will leave your site if your page is loading slowly and Google also takes the page loading time seriously to rank a website. So you should do your best to speed up your page loading.

One of the main problems for webpage slow loading is the javascript, especially the external javascript that is not from your own web server and you cannot control it. The reason why the web page gets slower when it comes with javascript is that when the web broswers come to read or download the contents of the javascript, it stops further reading until finishing reading the contents of the javascript. If the web server where you use the javascript to connect to gets hacked and responds very slowly, the webbrowsers will take longer time to read and as a result, your web page will be shown incompletely or just blank page, which depends on the design of your web page. There are several ways that you can better this situation. Now let's have a look at them one after another in the following:

1. Insert javascript just before the tag, < /body> as follows:


--------------------------------------------------------------------------------
< html>
< body>

< h1>designed by www.edusoftmax.com< /h1>

< p>designed by www.edusoftmax.com< /p>

< SCRIPT LANGUAGE="JavaScript" SRC="http://www.edusoftmax.com/">< /SCRIPT>
< /body>
< /html>
--------------------------------------------------------------------------------

2. Use defer = "defer" attribute as follows:


--------------------------------------------------------------------------------
< script type="text/javascript" src="http://www.edusoftmax.com/" defer="defer">
< /script>
--------------------------------------------------------------------------------

Note:

The "defer" attribute delays the downloading of the contents of the javascript until the whole html contents downloaded completely. You should also note that "defer" attribute works both inline and external javascript.

3. Add javascript in an html file and use iframe to display it. Let's look at it in the following:


--------------------------------------------------------------------------------

< html>
< body>

< h1>designed by www.edusoftmax.com< /h1>

< p>designed by www.edusoftmax.com< /p>

< IFRAME src="http://www.edusoftmax.com/reference.html" name="inside_frame" width="500" height="300" SCROLLING=NO SCROLLING=NO frameborder="0">
< /IFRAME>

< /body>
< /html>
--------------------------------------------------------------------------------

Note:
You add the javascript in the first example above


--------------------------------------------------------------------------------
< SCRIPT LANGUAGE="JavaScript" SRC="http://www.edusoftmax.com/">< /SCRIPT>
--------------------------------------------------------------------------------

into the file, "reference.html"
4. Use onload in < body> tag. Let's look at it in the following:


--------------------------------------------------------------------------------
< html>
< head>
< script type="text/javascript">
function myJavascript(){
var t=setTimeout("delayfunction()",3000);
}

function delayfunction(){
var urlsrc=document.createElement('script');
urlsrc.src="http://www.edusoftmax.com/";
document.getElementsByTagName('head')[0].appendChild(urlsrc);
}
< /script>
< /head>
< body onload="myJavascript()">
< /body>
< /html>
--------------------------------------------------------------------------------

Other tips on making web page loading fast
1. Use fast web hosting server.

2. Reduce image size by using software or specifying image dimensions. If possible, use fewer images.

3. Reduce using flash file.

4. Use CSS.

5. Avoid using nested tables.

6. Using fewer javascripts.

7. Avoid using redirects.

Final note:

After using the above techniques and your page still shows blank or partially displayed, it is very important for you to add a text "Page is loading" at the top so that the visitors may wait for a while.

website hosting tips, secrets, guide

This site provides users with the information about website hosting, website hosting tips, choose website hosting provider guide, how to choose free website hosting company secrets, web traffic interception, web traffic filter, web traffic redirect, and more.

Choosing a better website hosting company is very important for your online business. For most webmasters, they usually neglect some important factors which is directly related to their web traffic, that is, their online business. In the following, we will reveal some secrets for selecting a better website hosting provider -- our many years of experiences!

1. Read reviews.

Reading web hosting provider reviews is the first thing you should do. From there, you can find lots of information about the web hosting company of your candidates.

2. Check out the features of the web hosting provider.

The important features to check out are webspace, bandwidth, number of subdomain, email service, programming languages, and database. Please note that for some web hosting companies, they do not have free email services for free hosting package.

3. Check out the page loading speed and the uptime of the web hosting provider.

Before registration, you can go to their website to check out the page loading time several times, at the different time period. After registration, you can use your ftp software to check out if the uploading is fast. This is the very important factor for quality web hosting.

4. Check out their custom services.

You can call them at 1 - 2 a.m. because they should have 24 hours customer service or email them and see how long you can get response from them.

5. Check out web hosting reliability and protect your valuable traffic.

If you are doing the online business, it is very important for you to make web hosting reliability check. There are two main things that you need to check out. One is the web traffic interception and the other is the web traffic filter.

1) Traffic interception

For traffic interception, most of the webmasters never notice it. Some of the webmasters are very happy that they find a free web hosting with no banner insertion, unlimited bandwidth or lots of bandwidth, and lots of web space, but they never think of how much web traffic they lose if they choose a "unreliable" hosting provider. The following is what we found how your web traffic will be lost:

a. "Disable" your page for showing and make "Page not found" and then when visitors go to your page, they will be redirected to an advertisement page. The interesting thing is that at the time of the page redirection, your page can still be found on the web server and can also be downloaded.

b. Insert code at the end of your page or use other methods to redirect your traffic directly to their ad page, even before your page shown. For example, when your visitor click the link from a search engine after he makes a search with a keyword, he will see their ad page right away instead of your page. As a result, the search keyword does not match with the contents of the page shown or the contents supposed to be in the search engine database.

c. Replace the contents of your page with their ad contents.

Because of the above, over time (several months), your web traffic will be dropped greatly because the search engines lowered your website ranking after they repeatedly found "Page not found" and search query does not match with the web contents.

It is not easy for you to find out something happened like the above, but there are two techniques that you can use to give you some clues of a possible unreliable web hosting provider as follows:

a. You can enter a non-existing file to see if it will land on an ad page. You need to try it several times and at the different time period because they do it randomly. For some web hosting providers, you need to wait for some times after you see the 404 page from that hosting provider because they will redirect again to an ad page after serveral seconds.

b. After your page displayed over the internet, use View Source to open the source code of your page to see if any additional code from your web hosting provider is added to your page code.

If the above is confirmed, stop using their service as soon as possible before the big loss of your valuable traffic. This applies to both free and paid website hosting.

2) Traffic filter

For web traffic filter, some web hosting providers will filter the web traffic, that is, they will block the whole ips from the centain countries because of a few virus attacks from there. We think that blocking ips including good ones is not a good way to prevent virus attacks. It only drives their customers away.

If you think that this site is helpful, please recommend your friends to visit our site.

How to use treeview and child node in vb?

The TreeView control has a lot of options, but here is the basics of TreeView to get you started. The following is the syntax for adding a node:

TreeView1.Nodes.Add Relative, Relationship, Key, Text, Image, SelectedImage

You should be clear that all of the above parameters are optional, but you should know where the new item goes by using Relative and Relationship. Relative defines a relation, or an existing node, to the new node you are creating, while Relationship defines how the new node is related to this existing node. The following is a little reference of relationships for you:

tvwChild: new node is a child (one level down) of the specified node
tvwFirst: new node is first, at the same level of the specified node
tvwLast: new node is last, at the same level of the specified node
tvwNext: new node is after (at the same level) the specified node
tvwPrevious: node is before (at the same level) the specified node

You should also note that a TreeView gets its images from an ImageList, that is, if you want to add images, you need to add a ImageList control. The following is a little reference for ImagList:

1. In design mode, draw ImageList icon onto your Form.
2. Right-click on the ImageList and select Properties.
3. Choose the Images property page.
4. Click the Insert Picture button.
5. After selecting a picture file, add a unique key into the Key field.
6. Use the above syntax to add images.

The following is the code, example, steps for creating a TreeView in vb:

--------------------------------------------------------------------------------
1. In Component, add Microsoft Windows Common Controls 6.0
2. Go to design mode.
3. After seeing TreeView on Toolbox, drag the TreeView onto your form.
4. Once you have the TreeView, you can populate it in programming.
Add the following code in form_load.

Private Sub Form_Load()

TreeView1.Nodes.Add , , "root", "Root"
TreeView1.Nodes.Add "root", tvwChild, "child1", "Child1"
TreeView1.Nodes.Add "root", tvwChild, "child2", "Child2"
TreeView1.Nodes.Add "child1", tvwChild, "child_child1", "Child of Child1"
TreeView1.Nodes.Add "child2", tvwChild, "child_child2", "Child of Child2"

'add the following if you want Child1 of Child1 and Child1 of Child2 visible
TreeView1.Nodes("child_child1").EnsureVisible
TreeView1.Nodes("child_child2").EnsureVisible

End Sub

5. Add the following code in NodeClick if you want to perform
a specific task when you click it.

Private Sub TreeView1_NodeClick(ByVal Node As MSComctlLib.Node)
If Node.Text = "Child of Child1" Then
MsgBox "Child of Child1"
ElseIf Node.Text = "Child of Child2" Then
MsgBox "Child of Child2"
End If
End Sub

public class test  {
public static void main (String args[])
{

  FileOutputStream out; // declare a file output object
  //FileInputStream in;
  DataInputStream in; // = new DataInputStream(fstream);
  PrintStream p; // declare a print stream object

  try
  {
    // Create a new file output stream
    out = new FileOutputStream("c:\\test.txt");

    // Connect print stream to the output stream
    p = new PrintStream( out );

    p.println ("linda,smith");

    p.close();

    // file append
    FileWriter myWriter = new FileWriter("c:\\test.txt", true);
    myWriter.write("\n" + "String to be appended." );
    myWriter.close();


    FileInputStream fstream = new FileInputStream("c:\\test.txt");
    in = new DataInputStream(fstream);

    String line = null;
    int wordCount = 0;

    while ((line = in.readLine()) != null)
    {
      //use StringTokenizer to read comma delimited file or string
      StringTokenizer st = new StringTokenizer(line, ","); 
      while (st.hasMoreTokens())
      {
        System.out.println("The first character of word " + (++wordCount) + 
        " is: " + st.nextToken().substring(0,1));
      }
    }

    in.close();

    }
    catch (Exception e)
    {
      System.err.println ("Error writing to file");
    }

  }
}
--------------------------------------------------------------------------------

For reading file character by character, you can use the following code:

--------------------------------------------------------------------------------
import java.io.*;

public class ReadFileChar {

public static void main(String[] args) throws IOException
{
   BufferedReader in = null;
   int ich;        
   char ch;        
   int char_count=0; 

   // read character from test file
   in = new BufferedReader( new FileReader( "c:\\test.txt" ));

   while ( (ich=in.read()) != -1)
   {
      // extract character
      ch = (char) ich;
      char_count++;
      System.out.println( "count = " + char_count + " int = " + ich +
      " char = " + ch );
   }

   in.close();
}
}

vb: how to read and write array?

The following is the way to read and write array in visual basic programming:


Private Sub Command6_Click()

Dim LinesArr() As String
ReDim LinesArr(50)
Dim tmp As Integer
Dim LinesRead As Integer
LinesRead = 0

Open App.Path & "\sorteddate.txt" For Input As #1
Do While Not EOF(1)
If LinesRead = UBound(LinesArr) Then
ReDim Preserve LinesArr(UBound(LinesArr) + 50)
End If
'read a line
Line Input #1, LinesArr(LinesRead)
LinesRead = LinesRead + 1

DoEvents
Loop
'redim to actual size
ReDim Preserve LinesArr(LinesRead - 1)
Close #1

For tmp = 0 To UBound(LinesArr)
MsgBox LinesArr(tmp)
Next tmp
End Sub

Use of static array as follows:

Dim tmp As Integer

tmp1 = "001121"
tmp2 = "001122"
tmp3 = "001123"

Dim mArray, mDay
mArray = Array(tmp1, tmp2, tmp3)

' Return values assume lower bound set to 1
' (using Option Base statement).

'mDay = mWeek(2) ' mDay contains "Tue".
'mDay = mWeek(4) ' mDay contains "Thu".

For tmp = 0 To UBound(mArray)
MsgBox mArray(tmp)
Next tmp
