delete (COM) (External Interfaces Reference)

Delete COM control or server

Syntax

```
h.delete
delete(h)
```

Description

h.delete releases all interfaces derived from the specified COM server or control, and then deletes the server or control itself. This is different from releasing an interface, which releases and invalidates only that interface.

delete(h) is an alternate syntax for the same operation.

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('position',[300 300 500 500]);
cal = actxcontrol('mscal.calendar', [0 0 500 500], f);

TFont = cal.TitleFont
TFont =
   Interface.Standard_OLE_Types.Font

TFont.Name = 'Viva BoldExtraExtended';
TFont.Bold = 0;

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

```
TFont.release;
```

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

GFont = cal.GridFont
GFont =
   Interface.Standard_OLE_Types.Font

GFont.Size = 16;

When you're done, delete the cal object and the figure window. Deleting the cal object also releases all interfaces to the object (e.g., GFont):

```
cal.delete;
delete(f);
clear f;
```

Note that, although the object and interfaces themselves have been destroyed, the variables assigned to them still reside in the MATLAB workspace until you remove them with clear:

whos
  Name        Size                   Bytes  Class

  GFont       1x1                        0  handle
  TFone       1x1                        0  handle
  cal         1x1                        0  handle

Grand total is 3 elements using 0 bytes
