TextPopup Method

  • 项目

Use the TextPopup method to open a pop-up window.

The instance of the HTML Help ActiveX control that you reference using the TextPopup method does not need to specify a command.

This method can be used with either a compiled help (.chm) file or uncompiled HTML files.

Applies to

This method is independent of any of the HTML Help ActiveX control commands.
