ACC: How to Use a Toggle Button to Hide and Display a Subform

• Microsoft Access versions 1.0, 1.1, 2.0, 7.0, 97

SUMMARY

Novice: Requires knowledge of the user interface on single-user computers.

You can hide and show a subform by using a command button or toggle button. This article shows you how to create either a macro or a sample user-defined function that uses a command button or toggle button to hide and show the Quarterly Orders subform on the Quarterly Orders form in the sample database Northwind.mdb (or Nwind.mdb in Microsoft Access versions 1.x and 2.0).

This article assumes that you are familiar with Visual Basic for Applications and with creating Microsoft Access applications using the programming tools provided with Microsoft Access. For more information about Visual Basic for Applications, please refer to your version of the "Building Applications with Microsoft Access" manual.

NOTE: Visual Basic for Applications (used in Microsoft Access 97 and Microsoft Access for Windows 95 version 7.0) is called Access Basic in earlier versions. For more information about Access Basic, please refer to the "Introduction to Programming" manual in Microsoft Access version 1.x or the "Building Applications" manual in version 2.0.

NOTE: This article explains a technique demonstrated in the sample files, FrmSampl.exe (for Microsoft Access for Windows 95 version 7.0) and FrmSmp97.exe (for Microsoft Access 97). For information about how to obtain these sample files, please see the following articles in the Microsoft Knowledge Base:
