  • How do I create custom Controls for my VS2005 toolbox?

    - by end-user
    Ok, this question might more about design theory. I have successfully created controls that show up in my toolbox, so I'm pretty sure I have the process right. Also, my "AutoToolboxPopulate" is set to true, so things are showing up as I create them. My question is this: I'm sub-classing a native Control for specialized use. When I derive my class from an exposed concrete class, such as BulletedList, my custom Control appears in my Toolbox. However, when I drop it back to the parent, such as ListControl, my Control is not listed (actually it's grayed out when I "List All"). What am I missing?

  • Where is my software installed in Linux?

    - by user22861
    I use whereis matlab and find: /usr/local/bin/matlab , which is a very long bash file. How can I find where matlab is installed, I mean, its installed folder. EDIT: I used the following method: open matlab and use edit svds.m to open the svds.m file and the editor shows the folder:)

  • Adding Custom Pipeline code to the Pipeline Component Toolbox

    - by Geordie
    Add ... "C:\Program Files\Microsoft Visual Studio 8\SDK\v2.0\Bin\GacUtil.exe" /nologo /i "$(TargetPath)" /f  xcopy "$(TargetPath)" "C:\Program Files\Microsoft BizTalk Server 2006\Pipeline Components" /d /y to the 'Post Build event command line' for the pipeline support component project in visual studio. This will automatically put the support dll in the GAC and BizTalk’s Pipeline component directory on building the solution/project. Build the project. Right Click on title bar and select Choose items. Click on the BizTalk Pipeline Components tab and select the new component from the list. If it is not available in the list Browse to the BizTalk pipeline component folder (C:\Program Files\Microsoft BizTalk Server 2006\Pipeline Components) and select the dll.

  • Write a MAT file without using matlab headers and libraries.

    - by YuppieNetworking
    Hello all, I have some data that I would like to save to a MAT file (version 4 or 5, or any version, for that matter). The catch: I wanted to do this without using matlab libraries, since this code will not necessary run in a machine with matlab. My program uses Java and C++, so any existing library in those languages that achieves this could help me out... I did some research but did not find anything in Java/C++. However, I found that scipy on python achieves this with mio4.py or mio5.py. I thought about implementing this on java or C++, but it seems a bit out of my time schedule. So the question is: is there any libraries in Java or C/C++ that permits saving MAT files without using Matlab libraries? Thanks a lot

  • How do I change the Unit:Characters in Matlab?

    - by Jonas
    For portability, I set the units of my GUIs to 'characters'. Now I have a user who wants to use Matlab on his netbook, and the GUI window is larger than the screen (and thus cropped at the top). I think I could try and write something in the openingFcn of the GUI that measures screen size and then adjusts the GUI accordingly, but I'd rather avoid that, because I then need to deal with text that is bigger than the text boxes, etc. What I'd rather like to do is somehow adjust the unit 'character' on his Matlab installation. None of the font sizes in the preferences seem to have an effect on unit:character, though. Does anyone know whether there's a setting for that, which can be changed from within Matlab (I don't mind if it's something that is reset at every reboot, since I can just put it into the startup script)?

  • Matlab computations done over Apple Filing Protocol (AFP) depend on POSIX permissions, ignores ACLs

    - by flumignan
    I'm a system administrator and have never used Matlab, so forgive my general ignorance of the program. My users have encountered problems when executing scripted Matlab actions over AFP to a Mac OS X Server 10.6.7 where the access control list (ACL) should allow actions, but the POSIX-style permissions disallow the activity. It seems as if Matlab, run locally on the Mac workstations on datasets on the remote server, ignores the ACLs entirely. This is the only application I've ever seen behave this way. The server's filesystem is HFS+J and all other activity is performing as expected. These users cannot use CIFS because of our integration with external directory systems. In this example, the directory bxdata, the members of the group cibturner should be able to modify the files. Indeed, they can using any other method except via Matlab scripts. When the Matlab script hits these files, the POSIX permissions of 644 disallow modification. It's as if the ACLs are irrelevant.

  • What is the closest thing MATLAB has to namespaces?

    - by rlbond
    We have a lot of MATLAB code in my lab. The problem is there's really no way to organize it. Since all the functions have to be in the same folder to be called (or you have to add a bunch of folders to MATLAB's path environment variable), it seems that we're doomed have loads of files in the same folder, all in the global namespace. Is there a better way to organize our files and functions? I really wish there were some sort of module system...

  • Getting indices of most recent set of numbers in an array in Matlab?

    - by user2539781
    Let's say I have an array in Matlab: x = [1 1 1 2 2 2 3 3 3 3 2 2 3 3 3 1 1 1 1 1 2 2 2 2 3 3 3] I want the indices of the most recent set of consecutive '1's. In this case, I want the answer: answer = [16 17 18 19 20] % (which should correspond to the last sequence of 1's) I need an automated way to do this in Matlab, that will work with any size arrays, always giving me the indices for the last set of consecutive 1s. Any suggestions?

  • How to add XML elements into the toolbox in Visual Studio 2010 RC

    - by Alex Marshall
    I'm trying to edit an XML schema in Visual Studio 2010 Ultimate RC, but when I go to the toolbox (with the schema open and focused) there's absolutely nothing in the Toolbox view, even when every tutorial out there that I've read tells me that there should be. I've tried using the context menu option for resetting the Toolbox to no effect. Is there something I'm missing ? Something I need to install to get this feature of Visual Studio going ?

  • WiX Installing Server Control to Toolbox

    - by Jason
    I've got a server control in a dll deployed as part of a wix msi installation. I have gotten the installer to make the control available in the toolbox's ADD ITEMS window, but the contol isn't added to the the toolbox by default. How can I configure wix the installer to automatically add the toolbox item to, say, toolboxes to be shown for asp.net websites and web application projects under a new Category.

  • How to change Matlab program for solving equation with finite element method?

    - by DSblizzard
    I don't know is this question more related to mathematics or programming and I'm absolute newbie in Matlab. Program FEM_50 applies the finite element method to Laplace's equation -Uxx(x, y) - Uyy(x, y) = F(x, y) in Omega. How to change it to apply FEM to equation -Uxx(x, y) - Uyy(x, y) + U(x, y) = F(x, y)? At this page: http://sc.fsu.edu/~burkardt/m_src/fem_50/fem_50.html additional code files in case you need them. function fem_50 ( ) %% FEM_50 applies the finite element method to Laplace's equation. % % Discussion: % % FEM_50 is a set of MATLAB routines to apply the finite % element method to solving Laplace's equation in an arbitrary % region, using about 50 lines of MATLAB code. % % FEM_50 is partly a demonstration, to show how little it % takes to implement the finite element method (at least using % every possible MATLAB shortcut.) The user supplies datafiles % that specify the geometry of the region and its arrangement % into triangular and quadrilateral elements, and the location % and type of the boundary conditions, which can be any mixture % of Neumann and Dirichlet. % % The unknown state variable U(x,y) is assumed to satisfy % Laplace's equation: % -Uxx(x,y) - Uyy(x,y) = F(x,y) in Omega % with Dirichlet boundary conditions % U(x,y) = U_D(x,y) on Gamma_D % and Neumann boundary conditions on the outward normal derivative: % Un(x,y) = G(x,y) on Gamma_N % If Gamma designates the boundary of the region Omega, % then we presume that % Gamma = Gamma_D + Gamma_N % but the user is free to determine which boundary conditions to % apply. Note, however, that the problem will generally be singular % unless at least one Dirichlet boundary condition is specified. % % The code uses piecewise linear basis functions for triangular elements, % and piecewise isoparametric bilinear basis functions for quadrilateral % elements. % % The user is required to supply a number of data files and MATLAB % functions that specify the location of nodes, the grouping of nodes % into elements, the location and value of boundary conditions, and % the right hand side function in Laplace's equation. Note that the % fact that the geometry is completely up to the user means that % just about any two dimensional region can be handled, with arbitrary % shape, including holes and islands. % clear % % Read the nodal coordinate data file. % load coordinates.dat; % % Read the triangular element data file. % load elements3.dat; % % Read the quadrilateral element data file. % load elements4.dat; % % Read the Neumann boundary condition data file. % I THINK the purpose of the EVAL command is to create an empty NEUMANN array % if no Neumann file is found. % eval ( 'load neumann.dat;', 'neumann=[];' ); % % Read the Dirichlet boundary condition data file. % load dirichlet.dat; A = sparse ( size(coordinates,1), size(coordinates,1) ); b = sparse ( size(coordinates,1), 1 ); % % Assembly. % for j = 1 : size(elements3,1) A(elements3(j,:),elements3(j,:)) = A(elements3(j,:),elements3(j,:)) ... + stima3(coordinates(elements3(j,:),:)); end for j = 1 : size(elements4,1) A(elements4(j,:),elements4(j,:)) = A(elements4(j,:),elements4(j,:)) ... + stima4(coordinates(elements4(j,:),:)); end % % Volume Forces. % for j = 1 : size(elements3,1) b(elements3(j,:)) = b(elements3(j,:)) ... + det( [1,1,1; coordinates(elements3(j,:),:)'] ) * ... f(sum(coordinates(elements3(j,:),:))/3)/6; end for j = 1 : size(elements4,1) b(elements4(j,:)) = b(elements4(j,:)) ... + det([1,1,1; coordinates(elements4(j,1:3),:)'] ) * ... f(sum(coordinates(elements4(j,:),:))/4)/4; end % % Neumann conditions. % if ( ~isempty(neumann) ) for j = 1 : size(neumann,1) b(neumann(j,:)) = b(neumann(j,:)) + ... norm(coordinates(neumann(j,1),:) - coordinates(neumann(j,2),:)) * ... g(sum(coordinates(neumann(j,:),:))/2)/2; end end % % Determine which nodes are associated with Dirichlet conditions. % Assign the corresponding entries of U, and adjust the right hand side. % u = sparse ( size(coordinates,1), 1 ); BoundNodes = unique ( dirichlet ); u(BoundNodes) = u_d ( coordinates(BoundNodes,:) ); b = b - A * u; % % Compute the solution by solving A * U = B for the remaining unknown values of U. % FreeNodes = setdiff ( 1:size(coordinates,1), BoundNodes ); u(FreeNodes) = A(FreeNodes,FreeNodes) \ b(FreeNodes); % % Graphic representation. % show ( elements3, elements4, coordinates, full ( u ) ); return end
