Open Table Window

Created:12/10/2000
Description:

This sample shows how to open a the table window for the selected layer or standalone table in the table of contents. It provides the same functionality as the Open Attribute Table command on the layer context menu or the open command on the standalone table context menu.

A UIButtonControl is used so the command will only be enabled when a layer or standalonetable is selected in the table of contents.


How to use:
  1. Add a new UIButtonControl to any toolbar.
  2. Right-click on the command and select view source, then paste the code below here.
  3. Make sure the names of the controls match, the sample assumes the command is called UIButtonControl1.
  4. Completely close VBA so that events on the UIButtonControl fire correctly.
  5. Select a layer or standalone table in the table of contents and click the command.
  6. The table window for the selected layer or standalone table appears.
