If you try to insert the HHCtrl.ocx ActiveX control into a Microsoft Access form, you may receive the following error message:
The operation on the OLE object failed.
The OLE Server may not be registered.
To register the OLE Server, reinstall it.
The HHCtrl.ocx ActiveX control is an HTML Help control designed to insert features such as Help navigation and secondary window functionality into an HTML file. The control does not function in an Access form.
Use the TreeView control, which is similar in appearance to the HHCtrl.oxc ActiveX control. The TreeView control is designed to display data that is hierarchical in nature, such as organization trees, the entries in an index, or the files and folders on a disk, and it is supported in Access 2000.
For more information about how to use the TreeView control, open the MSDN Library - Microsoft Office 2000 Developer. In the Active Subset list, select Microsoft Office 2000 Developer Documentation.Click the Index tab, type TreeView controls, described as the keywords to find, and then click Display.
