Display Date time in Different DateTime Format in Vb6 or VB.net

If you want to display date and time or get system Date Time with various format or specific format then there are various type of method available in VB or VB.Net or C# code. In this post SKOTechLearn explain how to Display Date Time in Different DateTime Format in Vb6 or Vb.Net programming.

First, you have to know that, In programming you can use Date Time Formatting with two way:
  1. Predefined Format method
  2. User-defined Format method

 (1) Predefined Format Method:
Following details and code will describe, how these method will work to show predefined DateTime Format. Let's follow the following Table:

Predefined Format Method Uses
Now VB6.0, VB.Net
Date
Time VB6.0
Format (Now, "Short date") VB6.0, VB.Net
Format (Now, "Long Date")
Format (Now, "General date")
Format (Now, "Short Time")
Format (Now, "Long Time")
Today VB.Net
TimeOfDay
DateTime.Now.ToString() C#, VB.Net
DateTime.Today.ToString()
DateTime.Now.TimeOfDay.ToString()
DateTime.Now.ToShortDateString()
DateTime.Now.ToLongDateString()
DateTime.Now.ToLocalTime().ToString()
DateTime.Now.ToShortTimeString()
DateTime.Now.ToLongTimeString()

So, let's see the examples which can be use to format predefined type in VB6, VB.Net and C# code:

VB6.0:
 Private Sub MyButton1_Click()
   MyTxtBox1.Text = Now
   MyTxtBox2.Text = Date
   MyTxtBox3.Text = Time

   MyTxtBox4.Text = Format ( Now,  "Short date" )
   MyTxtBox5.Text = Format ( Now,  "Long Date" )
   MyTxtBox6.Text = Format ( Now,  "General date" )
   MyTxtBox7.Text = Format ( Now,  "Short Time" )
   MyTxtBox8.Text = Format ( Now,  "Long Time" )
 End Sub
After Executing application, you will find that the following output will be Shown:
Pedefined dateTime Format in Vb6.0

VB.Net :
 Sub MyDateBtnClick(sender As Object, As EventArgs)
  MyText1.Text = Now.ToString
  MyText2.Text = Today.ToString
  MyText3.Text = TimeOfDay.ToString
  MyText4.Text = Format ( Now, "Short date" )
  MyText5.Text = Format ( Now, "Long Date" )
  MyText6.Text = Format ( Now, "General date" )
  MyText7.Text = Format ( Now, "Short Time" )
  MyText8.Text = Format ( Now, "Long Time" )
 End Sub
This will show the following output:

PreDefined DateTime Format in C#

C# :
void MyDateBtnClick(object sender, EventArgs e)
  {
     MyCTxt1.Text = DateTime.Now.ToString();
     MyCTxt2.Text = DateTime.Today.ToString();
     MyCTxt3.Text = DateTime.Now.TimeOfDay.ToString();
     MyCTxt4.Text = DateTime.Now.ToShortDateString();
     MyCTxt5.Text = DateTime.Now.ToLongDateString();
     MyCTxt6.Text = DateTime.Now.ToLocalTime().ToString(); 
     MyCTxt7.Text = DateTime.Now.ToShortTimeString();
     MyCTxt8.Text = DateTime.Now.ToLongTimeString();
                    
   } 
After compiling this code, you will find the following output, when you click on Button.

So these are the predefined method in VB6, VB.Net and C#. Now Let's Find Custom method or User-Defined Method for Display Date and Time.

 (2)  User-defined Format method :
The following table describe the method of User-defined DateTime Format in VB6.0, VB.Net and C# code.
User Defined Format Method Use
Format ( now, “Your Formatted String” )  
VB6.0, VB.Net
Now.Today.ToString ( “Your Formated String” ) 
VB.Net
DateTime.Now.ToString ( “Your Formated String” )  
C#, VB.Net
DateAndTime.Now.ToString ( “Your Formated String” ) 
VB.Net

Why user defined format method is required? The answer is, in some case or sometime we required specific date time output on their application. So, the user defined format method is used.

Now, follow the following method for User Defined format process.

VB6.0 :
Private Sub UsrDtBtn_Click()
  UsrTxtBox1.Text = Format ( Now,  "dd" )
  UsrTxtBox2.Text = Format ( Now,  "dddd" )
  UsrTxtBox3.Text = Format ( Now,  "MM" )
  UsrTxtBox4.Text = Format ( Now, "MMMM" )
  UsrTxtBox5.Text = Format ( Now,  "yyyy" )
  UsrTxtBox6.Text = Format ( Now,  "dd/MM/yyyy" )
  UsrTxtBox7.Text = Format ( Now,  "dd-MM-yyyy" )
  UsrTxtBox8.Text = Format ( Now,  "MM/dd/yyyy hh:mm:ss AMPM" )
  UsrTxtBox9.Text = Format ( Now,  "hh:mm:ss AMPM" )
  UsrTxtBox10.Text = Format ( Now,  "hh:mm:ss" )
 End Sub
When you run VB Form, The following image output will be show.
User-Defined DateTime Format in VB6.0

VB.Net :
Sub UsrDTBtnClick(sender As Object, e As EventArgs)
    UsrTxt1.Text = Now.ToString ( "dd/MM/yyyy" )
    UsrTxt2.Text = Now.ToString ( "MM/dd/yyyy hh:mm:ss tt" )
    UsrTxt3.Text = DateAndTime.Now.ToString ( "dddd" )
    UsrTxt4.Text = DateAndTime.Now.ToString ( "MMMM" )
    UsrTxt5.Text = DateTime.Now.ToString ( "hh:mm:ss tt" )
    UsrTxt6.Text = DateTime.Now.ToString ( "dddd; dd-MMMM-yyyy" )
    UsrTxt7.Text = Format ( Now,  "dd-MM-yyyy" )
    UsrTxt8.Text = Format ( Now,  "MMMM, yyyy" )
        
 End Sub
Ok, Let's see the output:
User-Defined DateTime Format in VB.Net

C# :
void UserDtBtnClick(object sender, EventArgs e)
        {
            DateTime UsrDt;
            UsrDt = DateTime.Now;
            MyText1.Text = UsrDt.ToString ( "dd/MM/yyyy" );
            MyText2.Text = UsrDt.ToString ( "MM/dd/yyyy hh:mm:ss tt" );
            MyText3.Text = UsrDt.ToString ( "dddd" );
            MyText4.Text = UsrDt.ToString ( "MMMM" );
            MyText5.Text = UsrDt.ToString ( "hh:mm:ss tt" );
            MyText6.Text = UsrDt.ToString ( "dddd; dd-MMMM-yyyy" );
            MyText7.Text = UsrDt.ToString ( "MMMM, dd-yyyy" );
            MyText8.Text = UsrDt.ToString ( "dd-MMMM-yy" );
                    
        } 
After that we get following output:
User-Defined DateTime Format in CSharp

Now, these are the process to use to Display Date Time in Different DateTime Format in VB6.0 or VB.Net and C# with SKOTechLearn Tips.
