vb loop concept

A For...Next loop condition can be terminated by an Exit For statement. Consider the following statement block.

Dim x As IntegerFor x = 1 To 10Print xIf x = 5 ThenPrint "The program exited at x=5"End IfNext
The preceding code increments the value of x by 1 until it reaches the condition x = 5. The Exit For statement is executed and it terminates the For...Next loop. The Following statement block containing Do...While loop is terminated using Exit Do statement.
Dim x As IntegerDo While x < 10Print xx = x + 1If x = 5 ThenPrint "The program is exited at x=5"Exit DoEnd IfLoop

vb loop concept

Do While... Loop Statement
The Do While...Loop is used to execute statements until a certain condition is met. The following Do Loop counts from 1 to 100.
Dim number As Integernumber = 1Do While number <= 100number = number + 1Loop
A variable number is initialized to 1 and then the Do While Loop starts. First, the condition is tested; if condition is True, then the statements are executed. When it gets to the Loop it goes back to the Do and tests condition again. If condition is False on the first pass, the statements are never executed.
While... Wend Statement
A While...Wend statement behaves like the Do While...Loop statement. The following While...Wend counts from 1 to 100
Dim number As Integernumber = 1While number <=100number = number + 1Wend
Do...Loop While Statement
The Do...Loop While statement first executes the statements and then test the condition after each execution. The following program block illustrates the structure:
Dim number As Longnumber = 0Do number = number + 1Loop While number < 201
The programs executes the statements between Do and Loop While structure in any case. Then it determines whether the counter is less than 501. If so, the program again executes the statements between Do and Loop While else exits the Loop.
Do Until...Loop Statement
Unlike the Do While...Loop and While...Wend repetition structures, the Do Until... Loop structure tests a condition for falsity. Statements in the body of a Do Until...Loop are executed repeatedly as long as the loop-continuation test evaluates to False.
An example for Do Until...Loop statement. The coding is typed inside the click event of the command button
Dim number As Longnumber=0Do Until number > 1000number = number + 1Print numberLoop
Numbers between 1 to 1000 will be displayed on the form as soon as you click on the command button.
The For...Next Loop
The For...Next Loop is another way to make loops in Visual Basic. For...Next repetition structure handles all the details of counter-controlled repetition. The following loop counts the numbers from 1 to 100:
Dim x As IntegerFor x = 1 To 50Print xNext
In order to count the numbers from 1 yo 50 in steps of 2, the following loop can be used
For x = 1 To 50 Step 2Print xNext
The following loop counts numbers as 1, 3, 5, 7..etcThe above coding will display numbers vertically on the form. In order to display numbers horizontally the following method can be used.
For x = 1 To 50Print x & Space$ (2);Next
To increase the space between the numbers increase the value inside the brackets after the & Space$.
Following example is a For...Next repetition structure which is with the If condition used.
Dim number As IntegerFor number = 1 To 10If number = 4 ThenPrint "This is number 4"ElsePrint numberEnd IfNext
In the output instead of number 4 you will get the "This is number 4".

Guide to SSI (server side includes)

Don't worry, SSI doesn't require a rocket-science degree to understand and use. It is, however, a highly useful feature that lets you do incredibly time saving tasks such as include the contents of an external file across multiple pages on your site, or access and display server specific information such as the current server time, visitor's IP address, etc. In this tutorial I'll introduce new comers to the wonderful world of SSI! SSI is short for Server Side Includes, by the way.
Does my server support SSI?
The first thing that needs to be settled is whether your server supports SSI and have it enabled. SSI is a Linux/Apache specific feature, so if you're on a Windows server for example, you'll need to look for the Windows equivalent of SSI (sorry, not a Window's guy). To test if your server supports SSI then, you can run a simple test, by inserting the below code inside a webpage, and saving the page with a .shtml extension (the most common extension configured to parse SSI by default):

jQuery TreeView Menu

Description: jQuery TreeView Menu brings together all the most practical features requested in a Tree Menu into one awesome menu script. The markup for the menu is simply a HTML list before the script transforms it into a TreeView Menu that supports the following:
Three different ways to specify the initial state of the tree nodes:
1) All collapsed by default
2) All collapsed except ones with CSS class "open", or
3) All expanded except ones with CSS class "closed".
Ability to specify that only one tree branch is open at any time, collapsing any previous open branches.
Two types of persistence supported:
1) "Cookie" based, persisting last tree state before user navigates away from page.
2) "Location" based, expanding the branch or node with an "href" value that matches that of the current page (location.href). This lets you expand a particular branch that corresponds to the current page.
Supports optional animation with variable speed.
Controls can be added that collapses, expands, or toggles all nodes within a tree.
Supports optional asynchronous loading of the tree, so inner branches are loaded on demand based on JSON data returned from the server.
