If-else statements are a fundamental programming construct that allow you to control the flow of your code based on certain conditions. In Crystal Reports, you can use else if statements to perform different actions depending on the value of a field or expression.
This article will provide a brief overview of else if statements in Crystal Reports, and show you how to use them to create powerful and flexible reports. We’ll cover the following topics:
By the end of this article, you’ll have a solid understanding of how to use else if statements in Crystal Reports, and you’ll be able to use them to create reports that meet your specific needs.
If Then
// code to execute if condition1 is true
Else If Then
// code to execute if condition2 is true
Else
// code to execute if neither condition1 nor condition2 is true
End If
If Sales > 10000 Then
Commission = Sales * .1
Else If Sales > 5000 Then
Commission = Sales * .05
Else
Commission = 0
End If
Else If Crystal Reports is a conditional logic statement that allows you to control the flow of your report based on certain criteria. You can use Else If Crystal Reports to:
Else If Crystal Reports is a powerful tool that can be used to create more dynamic and interactive reports.
Else If Crystal Reports works by evaluating a series of conditions. If the first condition is true, then the associated action is performed. If the first condition is false, then the next condition is evaluated, and so on.
The syntax of an Else If Crystal Reports statement is as follows:
If Then
Else If Then
Else
End If
For example, the following Else If Crystal Reports statement would display the text “Male” if the value of the `Gender` field is “M”, and the text “Female” if the value of the `Gender` field is “F”:
If Gender = “M” Then
Text = “Male”
Else If Gender = “F” Then
Text = “Female”
Else
Text = “”
End If
There are several benefits to using Else If Crystal Reports, including:
The basic syntax of an Else If Crystal Reports statement is as follows:
If Then
Else If Then
Else
End If
The ` ` is a Boolean expression that evaluates to either true or false. If the condition is true, then the associated ` ` is performed. If the condition is false, then the next condition is evaluated, and so on.
The ` ` can be any valid Crystal Reports expression. This includes things like displaying text, performing calculations, and applying formatting.
You can use multiple Else If statements to create more complex conditional logic. For example, the following Else If Crystal Reports statement would display the text “Male” if the value of the `Gender` field is “M”, the text “Female” if the value of the `Gender` field is “F”, and the text “Unknown” if the value of the `Gender` field is not “M” or “F”:
If Gender = “M” Then
Text = “Male”
Else If Gender = “F” Then
Text = “Female”
Else
Text = “Unknown”
End If
To use multiple Else If statements, simply add additional `Else If` statements after the first `Else If` statement. Each `Else If` statement must have a different condition.
The following Else If Crystal Reports statement would display the text “Male” if the value of the `Gender` field is “M”, the text “Female” if the value of the `Gender` field is “F”, and the text “Unknown” if the value of the `Gender` field is not “M” or “F”:
If Gender = “M” Then
Text = “Male”
Else If Gender = “F” Then
Text = “Female”
Else
Text = “Unknown”
End If
You can also use Else If statements with Case statements to create even more complex conditional logic. A Case statement allows you to specify multiple values for a condition, and
Else If Crystal Reports is a conditional statement that allows you to specify different actions based on the value of a condition. For example, you could use Else If Crystal Reports to display a different message depending on whether a user is logged in or not.
To use Else If Crystal Reports, you first need to create a condition. This can be done using the If statement. The If statement has the following syntax:
If Then
Else If Then
Else
End If
In this example, the condition is ` ` and the action is ` `. The Else If statement will only execute the action if the condition is true. If the condition is false, the Else If statement will skip to the Else statement and execute the action there.
Once you have created a condition, you can use the Else If statement to specify different actions based on the value of the condition. For example, you could use the following Else If statement to display a different message depending on whether a user is logged in or not:
If User.IsLoggedIn Then
MsgBox “You are logged in.”
Else
MsgBox “You are not logged in.”
End If
In this example, the condition is `User.IsLoggedIn` and the actions are `MsgBox “You are logged in.”` and `MsgBox “You are not logged in.”`. If the user is logged in, the first action will be executed. If the user is not logged in, the second action will be executed.
Here are three examples of Else If Crystal Reports:
This example shows how to use Else If Crystal Reports to display a different message depending on whether a user is logged in or not.
If User.IsLoggedIn Then
MsgBox “You are logged in.”
Else
MsgBox “You are not logged in.”
End If
This example shows how to use Else If Crystal Reports to determine the shipping cost for an order. The shipping cost is determined by the weight of the order and the shipping method.
Dim ShippingCost As Double
If Order.Weight If…Then…Else.
3. In the If…Then…Else dialog box, enter the condition that you want to check.
4. Click the Then button and enter the block of code that you want to execute if the condition is true.
5. Click the Else If button and enter another condition that you want to check.
6. Click the Then button and enter the block of code that you want to execute if the second condition is true.
7. Repeat steps 5 and 6 for each additional condition that you want to check.
8. Click the Else button and enter the block of code that you want to execute if none of the other conditions are met.
9. Click OK.
