3 Ways To Pass Variables From Userform To Module In Vba

Passing variables from a UserForm to a module in VBA can be a bit tricky, but there are several ways to achieve this. In this article, we will explore three methods to pass variables from a UserForm to a module in VBA.

Why Pass Variables from UserForm to Module?

Before we dive into the methods, let's understand why we need to pass variables from a UserForm to a module. In VBA, a UserForm is a graphical user interface that allows users to interact with your application. However, the code that powers the UserForm is usually stored in a separate module. By passing variables from the UserForm to the module, you can perform calculations, manipulate data, and execute other tasks based on user input.

Method 1: Using Public Variables

One way to pass variables from a UserForm to a module is by declaring public variables in the module. A public variable is accessible from any part of the VBA project, including UserForms.

' In a module
Public UserName As String
Public UserAge As Integer

' In the UserForm
Private Sub btnSubmit_Click()
    UserName = txtName.Value
    UserAge = txtAge.Value
    Call MyProcedure
End Sub

In this example, we declare two public variables, UserName and UserAge, in a module. In the UserForm, we assign the values from the text boxes to these public variables when the submit button is clicked. We then call a procedure, MyProcedure, which can access these public variables.

Method 2: Using Properties

Another way to pass variables from a UserForm to a module is by creating properties in the UserForm. A property is a way to expose a variable or a value to other parts of the VBA project.

' In the UserForm
Public Property Get UserName() As String
    UserName = txtName.Value
End Property

Public Property Get UserAge() As Integer
    UserAge = txtAge.Value
End Property

' In a module
Sub MyProcedure()
    Dim frm As UserForm1
    Set frm = New UserForm1
    Dim userName As String
    Dim userAge As Integer
    userName = frm.UserName
    userAge = frm.UserAge
    ' Do something with userName and userAge
End Sub

In this example, we create two properties, UserName and UserAge, in the UserForm. These properties return the values from the text boxes. In the module, we create an instance of the UserForm and access these properties to get the values.

Method 3: Using Events

The third method to pass variables from a UserForm to a module is by using events. An event is a way to notify other parts of the VBA project that something has happened.

' In the UserForm
Public Event SubmitClicked(ByVal userName As String, ByVal userAge As Integer)

Private Sub btnSubmit_Click()
    RaiseEvent SubmitClicked(txtName.Value, txtAge.Value)
End Sub

' In a module
Sub MyProcedure()
    Dim frm As UserForm1
    Set frm = New UserForm1
    AddHandler frm.SubmitClicked, HandleSubmit
    frm.Show
End Sub

Private Sub HandleSubmit(ByVal userName As String, ByVal userAge As Integer)
    ' Do something with userName and userAge
End Sub

In this example, we create an event, SubmitClicked, in the UserForm. When the submit button is clicked, we raise this event and pass the values from the text boxes. In the module, we create an instance of the UserForm, add an event handler for the SubmitClicked event, and show the UserForm. When the event is raised, the event handler is executed, and we can access the values passed to the event.

In conclusion, passing variables from a UserForm to a module in VBA can be achieved using public variables, properties, or events. Each method has its own advantages and disadvantages, and the choice of method depends on the specific requirements of your project.
