Matlab m file into ocx file.

Can I convert my m file into an .ocx file ? I have converted my m file into a .dll file using the deploytool option. Whether can I do the former ? And I need to register that .ocx file in my Windows Activex Control List ? Please tell me how?

Do you have the Builder NE? If so, you can create a COM DLL out of your MATLAB code.

Hello Friedrich,

Yes I have. But still I want to use my m file as an OCX file. I did used builder NE and got a COM DLL out of that. Rather but I want an OCX file for my application. How could I do this.

Hi,

you wont be able to create an OCX file out of your MATLAB code.

I guess you want OCX to embed a MATLAB figure or your MATLAB GUI in some other application right? What other application is that?

I want to convert my m file and fig as an OCX file and embed it with Visual C++ application. If I cannot create an OCX file from my m file then what other way in which I can do this?

Luck for you that I am working on this :)

I would say make a basic C++ DLL and use the Windows API (SetParent) in order to force the figure on the C++ Control (e.g. a Panel). Its important that the control has its own Window Handle.

You can get the Window Handle of a figure in MATLAB like this:

function hWnd = hwnd()

plot(1:10);

warning('off','MATLAB:HandleGraphics:ObsoletedProperty:JavaFrame');

jFrame = get(gcf,'JavaFrame');

warning('on','MATLAB:HandleGraphics:ObsoletedProperty:JavaFrame');

while isempty(jFrame.fHG1Client.getWindow)

pause(.05)

end

hWnd = jFrame.fHG1Client.getWindow.getHWnd;

This works on Windows only.

I tested this approach in C# (Builder NE), Java (Builder JA), and Excel (Builder EX) and it worked fine.

You maybe need MoveWindow in addition, to resize the figure when the Panel resizes.

Thankyou Mr.Friedrich. I think this would help me more. Thanks a lot :)

@Friedrich: Instead of disabling the warning temporarily, you can use:

jFrame = get(handle(gcf), 'JavaFrame');

nice, thanks :)
