How to Create a Method for Calculating the Date and Time in VB.Net
This tutorial is all about How to Create a Method for Calculating the Date and Time in VB.Net.
In this tutorial, I’m going to teach you how to calculate the date and time of the present date in VB.Net. This will help you calculate the months, days, hour, minutes, seconds and milliseconds to the present date. Then, the exact time will appear in each fields accurately.
What is Visual Basic’s purpose?
The third-generation programming language was created to aid developers in the creation of Windows applications. It has a programming environment that allows programmers to write code in.exe or executable files. They can also utilize it to create in-house front-end solutions for interacting with huge databases. Because the language allows for continuing changes, you can keep coding and revising your work as needed.
However, there are some limits to the Microsoft Visual Basic download. If you want to make applications that take a long time to process, this software isn’t for you. That implies you won’t be able to use VB to create games or large apps because the system’s graphic interface requires a lot of memory and space. Furthermore, the language is limited to Microsoft and does not support other operating systems.
What are the most important characteristics of Visual Basic?
Microsoft Visual Basic for Applications Download, unlike other programming languages, allows for speedier app creation. It has string processing capabilities and is compatible with C++, MFC, and F#. Multi-targeting and the Windows Presentation Framework are also supported by the system, allowing developers to create a variety of Windows apps, desktop tools, metro-style programs, and hardware drivers.
So, let’s begin:
First, open the Visual Basic, create a new Windows Form Application and make the Form just like this.
After doing that, go to the solution explorer and click the view code.
In the code view, create a method for the calculation of the months, day and time.
[vbnet]
Private Sub CalculatingMethods()
‘INITIALIZE THE INSTANCE METHODS OF THE DATETTIME TYPE.
‘DEMONSTRATING THE DateTime.AddMonth, DateTime.AddDays , DateTime.AddHours
‘ , DateTime.AddMinutes , DateTime.AddSeconds AND DateTime.AddMilliseconds
Try
Dim date_Now As DateTime = DateAndTime.Now
lblOriginalDate.Text = date_Now
txtAns_Month.Text = date_Now.AddMonths(CInt(txtadd_Months.Text)).ToString
txtAns_Days.Text = date_Now.AddDays(CDbl(txtadd_Days.Text)).ToString
txtAns_Hours.Text = date_Now.AddHours(CDbl(txtAdd_Hours.Text)).ToString
txtAns_Minutes.Text = date_Now.AddMinutes(CDbl(txtAdd_Minutes.Text)).ToString
TxtAnsSecond. Text = date_Now. AddMinutes (CDbl (txtAdd_Second.Text)).ToString
txtAns_Milliseconds.Text = date_Now.AddMilliseconds(CDbl(txtAdd_Milliseconds.Text)).ToString
Catch ex As Exception
MsgBox(Me.Text, ex.Message)
End Try
End Sub
[/vbnet]
After creating a method, you have to set the initial value of the TextBox and the method that you have created to fire it on the first load.
[vbnet]
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
‘SET THE INITIAL VALUE IN THE TEXTBOX
For Each txt As Control In Me.Controls
If txt.GetType Is GetType(TextBox) Then
txt.Text = 7
End If
Next
‘SET THE METHOD TO CALCULATE IN THE FIRST LOAD
CalculatingMethods()
End Sub
[/vbnet]
And now, you have to set the methods that you have created in the click events handler of a “Calculate” Button.
[vbnet>
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
‘CALL THE METHODS TO CALCULATE EVERYTIME THE BUTTON IS CLICKED
Calculation_Methods()
End Sub
[/vbnet]
