Help Technique in Web applications

Introduction

“Help” is the most important part of our web applications, as mostly we don’t notice it, but sometimes it plays a very big role for saving our time and work.

Suppose a button has only an image, many times we are not able to understand what it means but when we place the mouse pointer over it, it shows the usage of that as a tooltip, which is a part of web help technique.

Many times, when we read a topic that contains special words, definition then don’t we have to search on the net about it, we just click and a small window opens with the description - this is also a part of “help” for web applications.

So here I'm going to explain some techniques about “How to add help to web applications”.

Displaying ToolTips

ToolTip is a very basic and very important part of the web, as I discussed in the introduction.

"Suppose a button has only an image, many times we are not able to understand what it means but when we place the mouse pointer over it, it shows the usage of that as a tooltip".

About

Tooltip shows at runtime, almost all "server" controls having this (tooltip) property inbuilt.

One important thing about tooltip is that Internet Explorer dosn’t accept the "tooltip" property of ASP.NET controls; it takes this property as "title".

In HTML controls, you have to use the "title" property instead of "tooltip" for controls to show the help.

Server control_

Code

<asp:ImageButton runat="server" ID="imgbutton" 

ToolTip="This is an eye,Click here to enter in web" ImageUrl="~/Lilac_by_KinkyPink.jpg"/>

Output

tooltip.JPG

Html control_

Code

<input type="image" title="This is an amazing eye" runat="server" 

src="Lilac_by_KinkyPink.jpg" style="height: 46px; width: 64px"/>

Output

The output will look the same as server control.

Displaying Help in a Popup Window

Sometimes while discussing a long term, we use some keywords that include long definitions and it is difficult to understand for a newbie. For this purpose, a popup window can be used for help purposes, it can be an HTML page or an .aspx page-depending on your requirement.

Code

<a href="#" onclick="window.open('procedure.htm','popup','left = 900 height=200,
    width=200,scrollbars=yes'); 
return(false);"> Procedure </a>are the most important topic of SQL.

Explanation

We have used # in href to give the current page reference and we used an onclick to open a new window "procedure.htm" which we have already created.

"Left = 900" is the pop window position and further are some properties.

Here procedure keyword is a link and the rest are simple chars.

Output

When you click on the "Procedure" keyword, it will open a new window containing the text entered in that page "procedure.htm" by you.

Try it.

HTML Help

If you have HTMLHELP.chm created in your system, then a simple link can be used to pop it up any time.

Download "HTML Help Workshop" for this type of help facility.

You can download it from the following link for free:

Installed.

Now follow these steps to create an HTML help workshop for a project, website, etc.

Just use these buttons to make your help project.

When you have done all the editing for creating help project, click on this "Compile HTML file" button and then give the path of that .hhp file.
