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?
Databases Visual Basic / Working with Database
In this section I'll talk about how to use the database features of VB, but I'll also talk about when those features are overkill and when simpler methods of data storage can be substituted for the VB database methods.
Database Controls Visual Basic / Working with Database
Database controls are ideal if you want to get in, get the job done, and then get out. Microsoft has done an excellent job of making it easy for a beginner to utilize existing databases in their applications. In this section we'll discuss the controls available to the database programmer.
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.
Creating database applications in VB-Part I Visual Basic / Working with Database
Visual basic allows us to manage databases created with different database program such as MS Access, Dbase, Paradox and etc. In this lesson, we are not dealing with how to create database files but we will see how we can access database files in the VB environment.
Graphics Commands Visual Basic / Multimedia
In VB there are a limited number of graphics features, but mixed with the judicious use of the Windows API a programmer can create some pretty fair graphics applications. When VB falls short, there is also no shortage of third party OCXs which can step in and add to the capabilites of VB.
Introduction to VB IDE Visual Basic / Getting Started
Like any other Windows application, VB consists of multiple windows which appear at startup. The windows that are displayed when you start VB are collectively known as the Visual Basic Integrated Development Environment (IDE).
Introduction to Procedures Visual Basic / General Development
A procedure is a set-aside assignment the compiler must take care of to complement a program. A program developer writes the procedure and a user would only see the result. There are two categories of procedures you will use in your programs: those that have already been created thus made available to you, and those you will create yourself.In v basic, like most other languages, there are two types of procedures: functions and sub routines.
Staying in Control War Against Bugs Visual Basic / Error Handling
Program bugs are highly ecological because program code is a renewable resource. If you fix a bug, another will grow in its place. And if you cut down that bug, yet another will emerge; only this one will be a mutation with long, poisonous tentacles and revenge in its heart, and it will sit there deep in your program, cackling and making elaborate plans for the most terrible time to strike.
