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.
regards, Daleel

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;

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')
