VBScript language supports following types of operators − Here, 4 and 5 are called operands and + is called the operator. Example 7.Let’s take an expression 4 + 5 is equal to 9. then expression 1 is true, otherwise the expression 2 is true. The program employ the If.Then.Else technique to check whether the entry is correct.ĮlseIf userNumber y, expression 1, expression 2) function evaluates the values of x and y, if x>y. After a number of trial, the user should get the right answer. Thr program will provide a hint whether the number is This is a guess a number game where the user key in a number and see check whether the answer is correct.
Let's say the commission structure is laid out as in the table below: This example calculate the commission based on sales volume attained. You can check out our animated passwords cracker program Example 7.2 Password = UsrTxt.Text = username And pwTxt.Text = password ThenĮlseIf UsrTxt.Text username Or pwTxt.Text password Then We have written the code so that both username and password must be correct to enable sign in if either one of them incorrect sign in will fail. For pwTxt, set the PasswordChr(password characters) property to * so that the password will appear as * instead of the actual character. Start VB6 and insert two textboxes on the form, rename them UsrTxt and pwTxt, the first textbox is to accept username input and the second one for If the username and password are correct, sign in is successful else sign in failed. This program simulates a sign in process. What action to take, whether to execute a program or terminate the program and Very powerful tools, they let the VB program compare data values and then decide To control the VB program flow, we can use various conditional operators.īasically, they resemble mathematical operators. For example, we can write a program that can ask theĬomputer to perform certain task until a certain condition is met. Problems intelligently so that it can provide useful output or feedback
Important part of programming because it can help to solve practical
In this chapter, you will learn how to create VBĬode that can make a decision when it process input from the user, andĬontrol the program flow in the process. In previous lessons, we have learned how to create Visual Basic code thatĬan accept input from the user and display the output without controlling
