MATLAB Function Reference

release (COM)

Release an interface

Syntax

• release(h)
  

Arguments

h
   Handle for a COM object that represents the interface to be released.

Description

Release the interface and all resources used by the interface. Each interface handle must be released when you are finished manipulating its properties and invoking its methods. Once an interface has been released, it is no longer valid and subsequent operations on the MATLAB object that represents that interface will result in errors.

Note    Releasing the interface will not delete the control itself (see delete), since other interfaces on that object may still be active. See Releasing Interfaces in the External Interfaces/API documentation for more information.

Examples

Create a Microsoft Calender application. Then create a TitleFont interface and use it to change the appearance of the font of the calendar's title:

• f = figure('pos',[300 300 500 500]);
  cal = actxcontrol('mscal.calendar', [0 0 500 500], f);
  
  TFont = get(cal, 'TitleFont')
  TFont =
     Interface.mscal.calendar.TitleFont
  
  set(TFont, 'Name', 'Viva BoldExtraExtended');
  set(TFont, 'Bold', 0);
  

When you're finished working with the title font, release the TitleFont interface:

• release(TFont);
  

Now create a GridFont interface and use it to modify the size of the calendar's date numerals:

• GFont = get(cal, 'GridFont')
  GFont =
     Interface.mscal.calendar.GridFont
  
  set(GFont, 'Size', 16);
  

When you're done, delete the cal object and the figure window:

• delete(cal);
  delete(f);
  clear f;
