What does this activeX error mean, how do i fix it?

Hi, Im attempting to use a finite element analysis program (infolytica Magnet), in conjunction with MAtlab R2011a by using activeX. I dont have much experience with activeX, however, i have found some code from the software distributor (Infolytica), which should allow both programs to communicate with each other. This code should open up the FEA software, and draw a line. code:

   MN6 = actxserver ('Magnet.Application');
   MN6.Visible = 'true';
   % set MagNet constants
   Consts = invoke(MN6, 'getConstants');
   % open new document
   dev = invoke(MN6, 'newDocument');
   % draw a line on the screen
   invoke(dev, 'newConstructionSliceLine', 3, 0, 5, 2)

error which i receive:

   ??? No public field Visible exists for class COM.Magnet_Application.

   Error in ==> Matlab_server at 2
   MN6.Visible = 'true';

Im not sure why this error is coming up. Any help, would be greatly appreciated.

Try this

set(MN6,'Visible',1);

I tried to connect Matlab R2020b to MAgNet 2020.1 and it worked and I can create the line.

The same example that you wrote here is also availble in the Magnet knowledge base.

Try

    methods( MN6 )
    MN6.Visible = true;

i tried it, this is the code:

MN6 = actxserver ('Magnet.Application');
methods( MN6 )
MN6.Visible = 'true';
% set MagNet constants
Consts = invoke(MN6, 'getConstants');
% open new document
dev = invoke(MN6, 'newDocument');
% draw a line on the screen
invoke(dev, 'newConstructionSliceLine', 3, 0, 5, 2)

and the output i get... but still get an error:

Methods for class COM.Magnet_Application:

addproperty         get                 move                set                 
constructorargs     getStackCalculator  propedit            
delete              interfaces          release             
deleteproperty      invoke              save                
events              load                send                

??? No public field Visible exists for class COM.Magnet_Application.

Error in ==> Matlab_server at 3
MN6.Visible = 'true';

Nothing was done in the FEA program... Thanx so much for the effort!

I should have proposed

    properties( MN6 )

Is it case sensitive? Try

    MN6.visible = 'true'

The value should it be char not logical?

[Guillermo]

please try set(mn6, 'Visible', 1) instead mn6.Visible = true;

No, you didn't try it. You continued to do

MN6.Visible = 'true';

while per said to do this:

MN6.Visible = true;

You're setting it to a string and he said to set it to a boolean. And your list shows methods, not properties. Try to get the properties to see if visible is one of them - it most likely is.

mn6.set('visible','true')
