Search a Record Using Visual Basic 6 and MS Access

In this code I would like to show you how to search a record using Microsoft Visual Basic 6 as my programming language and Microsoft Access as my database. I wrote this code as one of the programming project of my client before. You will find the code is very easy to understand and use in your programming projects using Visual Basic 6.

Thank you very much and Happy Productive Programming. If you have some questions please send me an email at jakerpomperada@yahoo.com and jakerpomperada@gmail.com. People here in the Philippines who wish to contact me can reach me at my mobile number 09173084360.

Employees Commission System in Visual Basic 6

Here is a code that I wrote for a client in United Kingdom I called this program Employees Commission System written entirely in Microsoft Visual Basic 6 and Microsoft Access as my back end database. This program will save,navigate and compute the commission of the employees in a company.

Thank you very much and Happy Productive Programming.

Prime Numbers in Visual Basic 6


One of the most fascinating inventions made by man is the computer. We use computers in our day to day activities such as in business, education, research, military applications, communications as well as entertainment. This computer becomes useful when there is software that runs on it. As we all know software is a collection of programs that makes our computer useful and interesting to work with.  There two classifications of software that we use in our computer system they are application software and system software. The first type of software is application software this type of software was designed to solve common problems that we encounter just like a word processing program like Microsoft Word we use this program to create and print our documents, computer games for instance is a good example of application software it was designed not only to entertain us but also it develops our thinking skills in making decisions and analysis of the situation. 

On the other hand system software was created to maintain the overall operation of our computer system examples of this is operating system that manages all the software and hardware components installed in our computer. Another example is your antivirus software which protects your computer against computer viruses that will damage our files and disable the normal operation of our computer in general.

In this article I will discuss about the program that I considered as application software by its nature I called this program Find the Prime Numbers.  Let me explain in the first place what is a prime number is  an number that is bigger than one and does not have a positive divisor other that one and itself.  We have learned the prime numbers during our elementary and high school days. Examples of prime numbers is  2,3,5,7,11,13,17,19, 23 and 29 for instance. In this program I will be using Visual Basic 6 as my programming language to illustrate of program Find Prime Number. I choose Visual Basic 6 because it is very easy to use and its ability to create sophisticated user interface compared to other programming language that you are the one who will write the statements for its design and layout stage. Having this advantage of Visual Basic 6 we can cut down big amount of our development time and we can focus on solving the problem on hand.

For our program the first thing that will do is to create the form and put a series of objects two command buttons, a list box where the list of prime number will be listed. The first command button is Find the Prime Number when the user click that button it will ask the user using a dialog box to enter the starting value of the number after the user give the initial values our program will ask the user to enter the last range or the maximum number which the generation of prime numbers will be stop.  When the user press the enter key the program will list the values of prime numbers from the given parameters earlier by our user.  Below is the command button cmdPrime for checking if the starting number and the end number by the user and then it will perform a series of computation to find the list of prime numbers. The result will be displayed in the list box adjacent to our command buttons.

Private Sub cmdPrime_Click()
    lstResults.Clear
    lblResults = "Results:"
    lngStart = InputBox("Enter the beginning number:", "Start Number")
    lngEnd = InputBox("Enter the ending number:", "End Number")
   
    lngStart = lngStart + 1
    Do Until lngStart = lngEnd
        If PrimeStatus(lngStart) = True Then
            lstResults.AddItem Str(lngStart)
            lngCount = lngCount + 1
        Else
         End If
        lngStart = lngStart + 1
    Loop
    lblResults = lblResults & " " & Str(lngCount)
    lngCount = 0
   
End Sub

This is the function that we have created to perform the computation and analysis of values of prime numbers in our program.

Function PrimeStatus(TestVal As Long) As Boolean
   Dim Lim As Integer
   PrimeStatus = True
   Lim = Sqr(TestVal)
   For I = 2 To Lim
      If TestVal Mod I = 0 Then
         PrimeStatus = False
         Exit For
      End If
        Next I
End Function
This is the general declaration of our variables it means we can use this variables anywhere in our program.
Public lngStart As Long
Public lngEnd As Long
Public lngCount As Long

Quit command button when the user click this button our program will be terminated and will return to our operating system.
Private Sub cmdExit_Click()
    End
End Sub

I just hope that you have learned something new about programming with this article Find the Prime Numbers using Visual Basic 6. If you have some comments, suggestions about this article feel free to email me I will be grad to answer your questions.

Thank you very much and Happy Productive Programming.
