Introduction

Have you ever faced a challenge while trying to manage the visibility of a text box in Microsoft Word based on a user’s selection in a drop-down menu? Specifically, if you're working with legacy Drop-Down Forms and you're trying to use VBA (Visual Basic for Applications) to make your document interactive, you may encounter some issues. This guide addresses these problems, offering you clear solutions to effectively show or hide a content control text box based on user-selected values.

Understanding the Problem

The core issue emerges when you're attempting to programmatically control whether a text box is visible or hidden based on the selection from a legacy drop-down form. The following error often pops up during this process:

This error typically arises when attempting to access a property or method that is either non-existent or being misused in your VBA code.

The Code Snippet

Here’s the VBA code some users typically start with:

While trying to implement this, issues can arise primarily regarding the method for accessing content controls and their properties.

Solution: Error Breakdown and Fixes

There are two common sources of errors found in the above code:

1. Accessing Content Controls

Problem: You cannot access a specific content control using a straightforward reference. VBA requires you to reference content controls either by their tag name or title. This creates a collection which can lead to complications if multiple content controls match the criteria.

Solution: Utilize the method SelectContentControlsByTag or SelectContentControlsByTitle to accurately retrieve your content control:

This line of code effectively targets the content control with the tag "Text1" and hides the text by modifying its font properties.

2. The Hidden Property Mistake

Problem: The content control objects do not have a Hidden property. Instead, you can manipulate the visibility by changing the font properties to hidden.

Solution: To hide the content control, as mentioned above, focus on the text range rather than the control itself. This is done using the Range property as shown in the previous code example.

Final Code Example

Here’s a corrected and complete version of your code for hiding/showing a text box based on the user-selected value:

Conclusion

Incorporating user interactions into your Word documents can significantly enhance their functionality and user experience. By understanding how to properly access and manage content controls within VBA, you can overcome common errors and create an interactive environment for your document users.
