Saving Your Work

Use these MATLAB functions to save and restore the state of a COM control object.

Function	Description
load	Load and initialize a COM control object from a file
save	Write and serialize a COM control object to a file

Save the current state of a COM control to a file using the save function. The following example creates an mwsamp2 control and saves its original state to the file mwsample:

• f = figure('position', [100 200 200 200]);
  h = actxcontrol('mwsamp.mwsampctrl.2', [0 0 200 200], f);
  h.save('mwsample')
  

Now, alter the figure by changing its label and the radius of the circle:

• h.Label = 'Circle';
  h.Radius = 50;
  h.Redraw;
  

Using the load function, you can restore the control to its original state:

• h.load('mwsample');
  h.get
  ans = 
       Label: 'Label'
      Radius: 20
  

Note    The COM save and load functions are only supported for controls at this time.
