PREFACE

The library is an important module for any educational institute. Library may contain thousands of books, and its management is a very tough job. The care should be taken for proper distribution of the resources. It should be managed in a manner so that its resources are used efficiently and conveniently. For this rules and rights should be provided to each user.

Manual management of such a large system is a very tideous job and errors may occur sometimes. This may affect the integrity and consistency of the system resulting in an improper resource distribution.

Here we have provided a full-fledged library management system, which will change the conventional manual management with a computerized library management system. We have tried our best to provide efficient and convenient transectory operations for librarian and users.

We are very much thankful to all those who directly or indirectly helped us in completing this project.

SOFTWARE STUDY

Software used for the development of the project are:

Microsoft Visual Basic 6.0 Microsoft Access 7.0

About Visual Basic 6.0

Visual Basic developed from the old Quick Basic language that was available under the DOS operating system. Quick Basic is the same language as BASIC; it is just Microsoft's product name for its version of BASIC. Visual Basic started out as the Brainchild of Alan Cooper. Cooper developed Visual Basic and then sold the product to Microsoft. Microsoft took the undeveloped product, code-named it "Thunder," the proceeded to create a programming language that would soon become one of the premier development environments in the windows environment.

Features Of Visual Basic

Visual Basic is a superset of the Visual Basic for Applications (VBA) programming language, which is included with most of the office products.

Includes a GUI development environment for development Windows applications.

Provides the ability to develop and test applications using an interpretive run function.

Allows for the creation of p-code and native code EXE files. P-code is a tokenized form of your source code that will be broken down at runtime into machine code. P-code can be stored more efficiently and executed faster than your source code, which is why Visual Basic will create this intermediary form.

Object-based development is possible using class modules. Rapid application development (RAD). Allows for the creation of COM components such as ActiveX

controls, DLLs, and EXEs. Has many internet development possibilities, including the

following:

1. ActiveX documents.2. DHTML applications that help you test browser

application.3. IIS applications that help you build server-based

application.4. Web browser control.5. FTP / HTTP support through a custom control.6. Winsock control.

4

Has an excellent integrated Help facility and Books Online? Including good debugging facilities. It has many wizards that help automate repetitive tasks.

Can be extended easily through the use of Windows API calls, hundreds of third party controls and DLLs, and integration with other Windows applications through Com and DCOM.

Uses many database access methods to get at different types of data.

Visual Basic Advantages

Visual Basic has many advantages over other development languages. Here's a list of some of these advantages:

Has A shorter learning curve and development time than C/C++, Delphi and even Power Builder.

Removes the complexities of the Windows API form the programmer.

Allows for rapid application development. Excellent for business applications. Used by most of the office suite tools as their macro

language, with the rest to follow. Other companies as well are starting to support VBA in their products, such as AutoCAD, Corel Draw, SAP, and many others.

Allow you to create ActiveX controls. Allows you to reuse third-party controls and component, as

well as your own. Supplies wizards to help you learn the language as well as

to enhance your productivity with the more difficult features of the language.

Object oriented in nature. It's not a complete OOP language, but it's getting closer.

Can integrate with the Internet on both the server side and the client side.

Can create ActiveX Automation servers. Integrates with Microsoft Transaction server. Can run servers either on the same machine or remotely on

another computer. This allows for true distributed processing.

Visual Basic has a large community of developers. (More than 3 million worldwide according to Microsoft). This means continued support for new developers.

MS Access 7.0

Microsoft Access is a powerful RDBMS tool. Microsoft Office Access, previously known as Microsoft Access, is a relational database management system from Microsoft that combines the relational Microsoft Jet Database Engine with a graphical user interface and software-development tools. It is a member of the Microsoft Office suite of applications, included in the Professional and higher editions or sold separately. In mid-May 2010, the current version Microsoft Access 2010 was released by Microsoft in Office 2010; Microsoft Office Access 2007 was the prior version. With its extensive features, it is easier to manage large volume of database. As the project requires large database MS ACCESS 7.0 is the perfect option as a back-end tool. Features of Ms Access 7.0

Users can create tables, queries, forms and reports, and connect them together with macros. Advanced users can use VBA to write rich solutions with advanced data manipulation and user control.The original concept of Access was for end users to be able to "access" data from any source. Other uses include: the import and export of data to many formats including Excel, Outlook, ASCII, dBase, Paradox, FoxPro, SQL Server, Oracle, ODBC, etc. It also has the ability to link to data in its existing location and use it for viewing, querying, editing, and reporting. This allows the existing data to change and the Access platform to always use the latest data. It can perform heterogeneous joins between data sets stored across different platforms. Access is often used by people downloading data from enterprise level databases for manipulation, analysis, and reporting locally.There is also the Jet Database format (MDB or ACCDB in Access 2007) which can contain the application and data in one file. This makes it very convenient to distribute the entire application to another user, who can run it in disconnected environments.One of the benefits of Access from a programmer's perspective is its relative compatibility with SQL (structured query language) — queries can be viewed graphically or edited as SQL statements, and SQL statements can be used directly in Macros and VBA Modules to manipulate Access tables. Users can mix and use both VBA and "Macros" for programming forms and logic and offers object-orientedpossibilities. VBA can also be included in queries.

Private Sub ReadMe()'HOW TO USE THIS CLASS AND MODULES

'1. Each form that is subclassing menus must have the 2 lines of code entered into the events shown below. The imagelist'name is optional and must be provided if icons are to be displayed. Any loaded form's imagelist can be used.

' MDI forms: If you are using MDI forms, if a child or parent is being subclassed,' you must subclass each child and the parent. Additionally, the MDI children use the' imagelist on the MDI form and MDI children do not reference the imagelist when' the SetMenus command is called. All subclassed forms call the ReleaseMenus on form unload.

' a. Form_Load: the last statement in this event should be: SetMenus [form handle (.hWnd)] , [ImageList Name for Icons]

52

' -- for MDI children: SetMenus [form handle (.hWnd)] << uses the parent MDI form's imagelist' b. Form_Unload: the 1st statement in this event should be: ReleaseMenus [form handle (.hWnd)]

'Example: SetMenus Me.hWnd, ImageList1

'2. DO NOT place breaks in the code when menus are subclassed or stop the code when menus are subclassed.'Doing so will crash VB. If you need to debug your code, set the public constant bAmDebugging=True within the'modModules module. This will prevent menus from being subclassed and will also prevent menus from displaying icons.'Be sure to set that constant = False when you want to see the icons.

'3. Do not put END statements in any of the forms that are subclassing menus. The End statement may fire before'the menus are released which will cause a critical error. The class and modules are written to release themselves'via the ReleaseMenus command.

'4. Assigning icons/bitmaps to your submenu items.

' a. Suggestion: Small icons (16x16) are best as far as clarity goes' b. Suggeston: If bitmaps are used, use smaller bitmaps (16x16) vs larger bitmaps (32x32)' c. Add the following flag immediately in front of the menu's caption: {IMG:#}' d. The # is the listimage icon index (1 thru n)' e. If you want to supply a manually trapped accelerator key add that to the end of the menu caption. See para 6. ' Example: menu caption is E&xit and image number 2 will be assigned to it and Alt+F4 will be the' manually trapped accelerator key

' {IMG:2}E&xit Alt+F4

'5. Optional transparency flag. By default, icons are NOT made to be transparent since they probably are anyway.'However, bitmaps by default ARE made to be transparentt. When transparency is invoked, the top left pixel'decides which color is made transparent throughout the image. Should you want to force an icon/bitmap to'be transparent or not be transparent, add the following code after the icon index in the caption header flag: ' |N to prevent transparency or |Y to force transparency

' Example: I have a bitmap in the imagelist which has a colored background that I do NOT want made transparent.

53

' Being a bitmap, by default, it will be made transparent. So I need to add then |N option to the menu caption:

' {IMG:3|N}CD &Player Alt+P

'6. Accelerator keys. The menu builder allows you to select many accelerator keys and will automatically trap them for you.'With this class & modules you can add other accelerator keys not provided by the menu builder (i.e., Alt+F4) and you'can use the same accelerator key on more than one menu -- not allowed via the menu builder.

' a. If you add an accelerator key manually (not via menu builder), you will need to trap those keys in the form's Key_Down' event by testing for KeyCode and Shift values

' b. In the examples above, manually adding an accelerator key is as simple as placing it at the end of the caption.

' c. The modules will align the accelerator keys neatly before they are displayed on the menu.

'7. To change the caption or image of a menu after the program is running, simply change it in VB via the Caption property.'The module will recognize the change and change the caption and/or assign the new icon. If you want to remove the icon'from the menu caption, do not include the {IMG:#} header or make the icon index = zero. Note. The menu caption when'referenced in VB will have the {IMG:#} header in the caption, but is stripped off when displaying the menu.

' Example: Change {IMG:5}Color Option is On to read Off whle using the same icon' Changet to: {IMG:5}Color Option is Off << that's it!

'8. Checkmarks and enabled/disabled menu items. The modules will draw a sunken box for menu items that are'checked and include the icon inside the sunken box, if one is assigned; otherwise a checkmark is placed inside' the sunken box. Disabled menu items are made to imitate regular disabled items to include the icon and caption.

'9. Separator bars. You can add text to the separator bars. While in the menu builder, include the hyphen/dash to'designate the menu item as a separator and then add the text immediately after. {IMG:#} headers will not be'recognized on separators, nor will accelerator keys be spaced with other accelerator keys. Separator bars,'regardless if they have text or not, are not clickable.

54

' a. By default, text on separator bars are one font point lower than the system menu font and a font type of Tahoma.

' b. The color of the text on the separator will be the same color as the color used to highlight a menu item with the mouse.

' c. If the bAmDebugging flag is set to True, then the separator bars will not be disabled. Nor will they look disabled.

'10. These modules do not interfere with any menu events (i.e., click events, popup position, etc, etc, etc are not affected)

'11. These modules to not draw parent level menus. In other words, menus that have submenus are not drawn by the'modules -- but their submenus are. The class and modules were written to use Windows default menu style but add'the capability of icons to submenus. Therefore, foreground colors, fonts and background colors are not supported'as this would not mirror the parent level menu items.

'12. The basic premis. Provide a somewhat small class and modules that can be added to any project to support'icons and make the subclassing easy. Other projects available on the web will draw entire menus but come at'a price -- large number of classes and modules added to each project or forcing DLLs on other users.

'13. Sidebars. These are bitmaps or text along the left edge of a menu panel.'You can add a picture or text by following these format rules. The images on'a sidebar will be shrunk to fit if necessary, otherwise centered into the sidebar.'When images are shrunk, they are done proportionally, therefore, there may be'space around the image within the sidebar. If the formatted string is incorrect,'no sidebar will be shown.

'That menu item MUST be visible, otherwise no sidebar will be drawn

'On any submenu of a menu, add the following formatted string'Don't use spaces. Spaces below done for readability

' a. For images in controls like image controls, pictureboxes, etc:

' {SIDEBAR:control | BCOLOR:color }' Example: {SIDEBAR:image1|BCOLOR:background}

' b. For images passed as handles. You must provide much more information' {SIDEBAR:handle | BCOLOR:color }' (SIDEBAR:120928|BCOLOR:background}

' The values for the tags in the above strings are as follows:' If image is passed as a control, then the following is mandatory

55

' control: This is the control name with a picture property' and must exist on the same form that is subclassing menus' This also applies to MDI parents and children' color: optional. Default is NONE. The color is used to fill in the space' between the image and the sidebar when the image doesn't completely' fill up the sidebar. Values for Color can be...' 1. The numerical value of a color (i.e., BCOLOR:65535)' 2. NONE. This will not fill in the space between image and sidebar' 3. BACKGROUND. This will fill the space with the images top left pixel color' If image is passed as a handle vs a form control, then this is mandatory:' handle: the numerical picture.handle should be a bitmap! Icons will draw at 16x16

' c. For Text: don't use spaces except in the caption if needed. Spaces below done for readability' {SIDEBAR:TEXT | CAPTION:caption | FONT:fontname | FCOLOR:color | BCOLOR:color | FSIZE:font_size}' Optional flags can be added by preceding them with a pipe |' BOLD, ITALIC, UNDERLINE, GRADIENT' Example: {SIDEBAR:TEXT|CAPTION:La Volpe|FONT:Algerian|FCOLOR:16777215|BCOLOR:255|FSIZE:12|GRADIENT}

' The values for the tags in the above string are as follows:

' caption: mandatory. The text you want displayed on the sidebar. The text font size will be' be 11 by default but reduced to fit the sidebar if needed' fontname: Optional. The font to use. This font should be scalable. In other words,' if the font size can be set as an odd number then don't use it.' The default font will be Tahoma' forecolor color: optional. Numerical value for the color of the text. Default is black' backcolor color: optional. Numerical value for the back color of the sidebar. Default is menu color' font_size: optional. Whole number of a font size. Default is 11' BOLD: optional. If supplied, font is bolded. Default is no bolding' ITALIC: optional. If supplied, font is italicized. Default is no italics' UNDERLINE: optional. If supplied, font is underlined. Default is no underlining' GRADIENT: optional. If supplied, it is the word GRADIENT and will color the sidebar' in the backcolor, from black to backcolor, bottom to top.

'Suggestions? I will entertain any suggestions (always have). However, I do not plan on making this class draw'entire menus. I thought of the possibility of having icons & bitmaps on menus that are not loaded into an'imagelist. However, I don't immediately see why that would be necessary. If you have a need for that'capability, let me know -- I have already ran test code to make that happen.End Sub
