Users to automate tasks and create custom solutions to make their work more efficient. One key aspect of VBA is its use of objects, properties, and methods. In this blog post, we will specifically focus on the Property Set statement in VBA and how it can be used to enhance your code.
VBA Set Statement in VBA
Purpose of Property Set Statement
The Property Set statement allows you to assign an object reference to a variable. This means that you can use the variable to refer to the object and access its properties and methods. It is commonly used when working with objects in VBA, especially when dealing with collections of objects. Without the Property Set statement, you would have to refer to the object directly, which can make your code more cumbersome and less flexible.
Syntax of Property Set Statement
The syntax for the Property Set statement is as follows:
Set variable = object
Where ‘variable’ is the name of the variable you want to use to refer to the object, and ‘object’ is the name of the object you want to assign to the variable. The ‘Set’ keyword is crucial and is used to indicate that you are assigning an object reference to the variable.
Examples of VBA Property Set Statement
Now that we understand the purpose and syntax of the Property Set statement, let’s look at some practical examples of how it can be used in VBA.
Example 1 – Setting Range Object
One common use of the Property Set statement is when working with ranges in Excel. For instance, let’s say we want to loop through a certain range and change the format of each cell. Instead of typing out the range every time, we can use the Property Set statement to assign the range to a variable and then use that variable in our code.
Dim rng As Range
Set rng = ActiveSheet.Range("A1:C10")
For Each cell in rng
cell.Font.Bold = True
Next cell
In this example, we have assigned the range A1:C10 on the active sheet to the variable ‘rng’ using Property Set statement. This allows us to easily reference the cells in that range in our ‘For Each’ loop.
Example 2 – Using Property Set with Collections
Another handy use of the Property Set statement is when working with collections of objects. Let’s say we have a collection of worksheets in our Excel workbook and we want to loop through each one and change the font color of a specific range. We can use the Property Set statement to assign each worksheet in the collection to a variable and then use that variable in our code.
Dim ws As Worksheet
Dim wsCol As Worksheets
Set wsCol = ThisWorkbook.Worksheets
For Each ws in wsCol
Set rng = ws.Range("A1:C10")
rng.Font.Color = RGB(255,0,0)
Next ws
In this example, we have used the Property Set statement to assign each worksheet in the ‘Worksheets’ collection to the variable ‘ws’. This allows us to easily access and manipulate each worksheet in our loop.
Example 3 – Setting Outlook Object
The Property Set statement is not limited to just Excel. It can be used in other Microsoft applications, such as Outlook. Let’s say we want to create a new email and set the recipient, subject, and body text using VBA. We can use the Property Set statement to assign the Outlook application and the email objects to variables and then use those variables in our code.
Dim olApp As Outlook.Application Dim olMail As Outlook.MailItem Set olApp = New Outlook.Application Set olMail = olApp.CreateItem(olMailItem) olMail.To = "example@email.com" olMail.Subject = "This is a test email" olMail.Body = "Hello, this is a test email using VBA!" olMail.Send
In this example, we have used the Property Set statement to assign the Outlook application and the email object to the variables ‘olApp’ and ‘olMail’ respectively. This allows us to easily manipulate the email before sending it.
Example 4 – Setting Access Form Object
The Property Set statement can also be used in Access to refer to objects on a form. Let’s say we have a form with multiple text boxes and we want to loop through them and clear their values. We can use the Property Set statement to assign each text box object to a variable and then use that variable in our loop.
Dim frm As Form
Dim txtBox As TextBox
Set frm = Forms!frmExample
For Each txtBox In frm.Controls
If TypeName(txtBox) = "TextBox" Then
txtBox.Value = Null
End If
Next txtBox
In this example, we have used the Property Set statement to assign each text box object in the ‘Controls’ collection of our form to the variable ‘txtBox’. This allows us to easily loop through the text boxes and manipulate them.
Example 5 – Assigning Object to Object Variable
Lastly, the Property Set statement can be used to assign one object to another object variable. This is useful when you want to manipulate an object but also want to store its original state to use later.
Dim ws As Worksheet
Dim wsCopy As Worksheet
Set ws = ThisWorkbook.Worksheets("Sheet1")
Set wsCopy = ws
'Some code to manipulate ws
ws.Range("A1").Value = "Example"
MsgBox wsCopy.Range("A1").Value 'This will also display "Example"
In this example, we have used the Property Set statement to assign the ‘ws’ object to the ‘wsCopy’ object. This means that any changes made to ‘ws’ will also be reflected in ‘wsCopy’.
Important Notes & Remarks
There are a few things to keep in mind when using the Property Set statement in VBA:
- The variable you are assigning the object to must be declared as an object type. For instance, ‘Dim ws as Worksheet’.
- The object being assigned must be of a compatible type with the variable. For example, you cannot assign a range object to a worksheet variable.
- If you assign an object variable to another object variable, both variables will refer to the same object. Any changes made to one variable will also affect the other.
In Conclusion
The Property Set statement is a powerful tool in VBA that allows you to assign an object reference to a variable. This makes your code more flexible and allows for easier manipulation of objects. We have looked at some practical examples of how it can be used with different objects in various Microsoft applications.
Remember to keep in mind the important notes and remarks when using the Property Set statement in your code. Give it a try in your next VBA project and see how it can enhance your code.
