I would like to learn how to call sub-procedure in Visual Basic? What is the use of “Call” keyword and what is the main purpose of this keyword? Can you help me create a program that will call sub procedure? How can I implement this in my program? Can you show me how to do this? Can you explain the syntaxes that we need to use for this program? What are the objects that we need to include in this program? Please provide me guidance. Thank you!
Calling options to make the program more efficient
It’s easy to implement and call functions or sub-functions. This usually implemented if you have to use the functions processes in a program for multiple time. This is for the benefit of making the program smaller and lessen lots of codes. I created a program that will illustrate how to implement this.
You just need the following.
1. Form 1 = you can manipulate this for or maybe add color.
2. 3 textboxes >> with name properties of strBox1, strBox2, strSum.
3. 1 Command button.
Here are the codes.
Public Class Form1
Public Function add_values()
intSum.Text = Val(intBox1.Text) + Val(intBox2.Text)
Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click
The part that says Public Function add_values(), you have to type it manually. The user will be the one to define it. The “Call” just called and initiated the arithmetic operation – add. Notice that I placed the “Val” before the expression? We need to indicate it every because if not, it will only combine 1 and 2 that is equivalent to 12 not 3.
