ActiveX Control Support in Office 2000

The following considerations apply when using ActiveX® controls with Office 2000 applications. You may encounter some of the behavior described in the following list when working with the System Monitor control in Office 2000 containers:

• Microsoft® Excel charts cannot contain ActiveX controls. Controls can be placed on top of chart objects that are embedded in a worksheet, but such controls will not be active when the chart is activated.
• There is no automatic downloading of ActiveX controls embedded in Office 2000 documents when browsing using Internet Explorer.
• In Microsoft Excel, restarting the computer with the control active (selecting Shut Down) will result in the message "Cannot quit Microsoft Excel."
• ActiveX controls may behave unpredictably when seen in multiple views of the same Microsoft Word document (for example, when using New Window or the Split pane).
• ActiveX controls in an Excel worksheet cannot be activated if Excel is in-place active within a container—that is, if an Excel worksheet is embedded in another container (such as a Word document), the controls in the worksheet are displayed correctly and can be selected in Design Mode in this case; however, the controls are not in-place active.
• Office 2000 documents do not support multithreaded controls. When the System Monitor control is configured to collect data automatically, it causes a separate thread to run, causing problems with Office 2000 applications. Therefore, Microsoft recommends configuring manual updating when hosting the control in Office 2000 applications.
