We can use various conditional operators to control the VB program flow. Basically, they resemble mathematical operators only. Conditional operators are very powerful tools and they let the VB program compare data values and then decide what action to take, whether to execute a program or terminate the program and etc. These operators are shown in following table:

In addition to conditional operators, there are a few logical operators which offer added power to the VB program and these are shown in Table below:

To effectively control the VB program flow, we shall use If...Then...Else statement together with the logical operators and conditional operators and the general format for the if...then...else statement is as follows:
