Inserting Text into a Richtext Textbox Using VBA Code

In the world of Microsoft Access, one common task that developers often encounter is the need to programmatically insert text into a richtext textbox. While this might seem straightforward, it can pose significant challenges, especially when dealing with hidden formatting codes in richtext controls. If you’ve ever found yourself struggling with this issue, read on to explore a step-by-step solution that will enable you to insert text exactly where the user's cursor is located.

The Problem

When attempting to insert text into a richtext textbox using VBA, many developers encounter issues with cursor placement. Here’s the typical challenge:

Inconsistent Insertions: The new text is inserted at an incorrect position relative to the user’s cursor, often appearing earlier than expected.

Formatting Confusion: Hidden formatting codes (like <div> or similar tags) complicate matters, causing .SelStart and .SelLength properties to mislead.

In this guide, we’ll walk through a solution that effectively addresses these problems by providing a clear process for inserting text at the correct cursor position.
