4. Usage
You can assign values such as integers, strings, variables, and arguments. Here are some examples of how to use the "Assign" activity:
(1) Assigning a Numeric Value
This example demonstrates replacing a numeric value using the "Assign" activity. First, create a variable named Test_Value (Int32 type) in the Variables panel with a default value of 10. For instructions on creating variables, refer to "Creating Variables."
To display the current value of the variable Test_Value in the "Output," drag and drop the "Core > Log Message" activity from the toolbox into the Designer panel.
Enter the variable Test_Value in the "Message" property.
Drag and drop the "Original > Assignment" activity onto the designer panel.
Input the variable Test_Value into the "Target" property and enter 10000 into the "Value" property.
To verify the value of the variable Test_Value, place the "Log Message" activity again, input the variable Test_Value into the "Message" property.
Click "Home > Start" or press the "F5" key to execute and check the "Output." You will see that the value of Test_Value has been replaced from 10 to 10000 due to the use of the "Assignment" activity.
(2) Assigning a Calculation Expression As an example, we will input a string calculation expression. First, create the variable Test_String (of type String) with a default value of "Before" in the variable panel. Please refer to "How to create variables" for instructions on how to do this.
Place the "Log Message" activity and input the variable Test_String into the "Message" property.
Drag and drop the "Original > Assignment" activity onto the designer panel.
Input the variable Test_String into the "Target" property and enter Test_String + "After" into the "Value" property.
To verify the value of the variable Test_String, place the "Log Message" activity again and input the variable Test_String into the "Message" property.
Click "Home > Start" or press the "F5" key to execute and check the "Output." You will see that the value of Test_String has been replaced from "Before" to "BeforeAfter" due to the use of the "Assignment" activity.
In this case, we assigned a calculation expression with a String type variable, but it can also be used as a counter. For example, by preparing a variable Counter (of type Int32) and entering Counter into the "Target" property and Counter + 1 into the "Value" property, it can be used as a repeating counter.
You can specify not only variables but also arguments in the "Target" property, and in the "Value" property, you can add multiple variables together.
