Hello all,

I am working with a uEye IDS camera. Which can be used with ActiveX and .NET. I want to make use of the .NET libraries available in the DLL file. However i am unable to do so. My code:

clc
clear all
close all
asm= NET.addAssembly('C:\Programme\IDS\uEye\Develop\DotNet\uEyeDotNet.dll');
list=asm.Classes;
cam = uEye.Camera;
cam.Init;
cam.Memory.Allocate;
cam.Acquisition.Capture;

next step would be to display the image set, but, there is no property available there. like, available syntax example from the manufacturer:

uEye.Camera cam = new uEye.Camera();
cam.Memory.Allocate(out s32MemId);
cam.Acquisition.Capture(s32Wait);
cam.DisplayImage.Set(s32MemId, s32DisplayHandle, s32Mode)

I know it isn't the way we program in Matlab. The syntax is something like VB or something no idea.

I can not display anything. I am only able to run my code which has output.

Experts, please help.

I've written a little function that will load the assembly if required - the .NET assembly should be located inside the same folder as this function (I actually have this as part of an object, so have adapted it a little for this purpose):

%  Check if required .NET assemblies have been loaded; load if required
function LoadAssembly(varargin)
%  Get list of loaded assemblies
asm = System.AppDomain.CurrentDomain.GetAssemblies;
  
for narg=1:nargin
  if ~any(arrayfun(@(n) strncmpi(char(asm.Get(n-1).FullName), ...
      varargin{narg}, length(varargin{narg})), 1:asm.Length))
    str = which('LoadAssembly');
    ind = strfind(str, filesep);
    str = str(1:ind(end));
    NET.addAssembly(fullfile(str, [varargin{narg} '.dll']));
  end
end
    
end % function LoadAssembly
