Working With Files Visual Basic / File Manipulation
Is it possible to save data accepted by a VB program into a storage device, such as a hard disk or diskette, or even CDRW? The answer is possible. Is this chapter, we will learn how to create files by writing them into a storage device and then retrieve the data by reading the contents of the files using customized VB programs.
Managing Visual Basic Data Visual Basic / Getting Started
There are many types of data we come across in our daily life. For example, we need to handle data such as names, addresses, money, date, stock quotes, statistics and etc everyday. Similarly in Visual Basic, we are also going to deal with these kinds of data. However, to be more systematic, VB divides data into different types.
Creating VB Function For MS Excel Visual Basic / Functions
You can create your own functions to supplement the built-in functions in Microsoft Excel spreadsheet which are quite limited. These functions could be very useful and powerful if you know how to program them properly. One main reason we need to create user defined functions is to enable us to customize our spreadsheet environment for individual needs.
Databases Visual Basic / Working with Database
Most Visual Basic applications must, regretfully, have dealings with a database somewhere along the line. The current propaganda figure is 95 percent. This data access thing can be a dirty business, so if you have to do it, do it once, do it right, and forget it forever. This means write such a generic and reusable thing that even a gibbering Java programmer will be able to reuse it. How about a middle-tier DLL that you can use over and over again?
SQL Visual Basic / Working with Database
To selectively display records in a recordset, the feature to use is SQL - Structured Query Language. By creating a query (a text string which tells VB what to include in a recordset or what actions to take against the data in a recordset) you can greatly simplify the code you have to write in an application that utilizes databases.
Distribution of Applications Visual Basic / Miscellaneous
There are programmers out there who program solely for themselves. They write code/applications and no one but them ever sees their applications. However, most of you are like me and we want to revel in the accolades that our friends and peers heap on us when we provide them with exactly the right program to meet a need that they have expressed!.
Dynamic Usage of Event Handlers in VB.NET Visual Basic / VB.Net
With Events and Handles clause requires form us to declare the object variable and the event handler as we write our code, so linkage is created upon compilation. On the other hand, with AddHandler and RemoveHandler, linkage is created and removed at runtime, which is more flexible.
Drag & Drop Visual Basic Visual Basic / Complete Projects
You see it in just about every Windows application, so how can you do it in your VB application? Fortunately VB provides built-in tools to make it easy for you. While the code you write to respond to a drag and drop operation can be fairly complex, the mechanics of a drag and drop operation are fairly simple and logical.
How To Program A Barcode Maker Visual Basic / Miscellaneous
This tutorial will show you how to input data into a text box and get a barcode image from it. You will also learn how to work with clipboard and checksum controls.
Printing Visual Basic / Miscellaneous
An important fact is that how well the data is presented to the user can make or break the success of the application. Learning to use the printing tools of VB is critical to your success as a programmer.
Forms Visual Basic / Getting Started
Visual Basic forms are windows. It's an important piece of data because it ties the concept of a form in with everything you already know about Windows applications.)! This section provides additional details about how VB handles forms.
Programming With Variants Visual Basic / General Development
Microsoft Visual Basic 6 further enhances the Variant data type from the previous version so that it can now hold user-defined types (UDTs). This creates yet another reason why you should become familiar with Variants and what they can do. In this tutorial I will take an in-depth look at Variants and discuss the benefits and pitfalls of programming with them.
