I am trying to combine two different VI in labview, and am not sure where to start. I am at a beginner level, and I tried copy and pasting the block diagram from one VI into the block diagram of another. I don't know where to go from there; the controls for the second diagram don't show up after copy pasting it, and I couldn't put the whole thing into a subvi since it has more than 28 connectors. I don't think copy pasting it will work, but I was wondering if anyone knew where to start.
How about using SubVIs?
"After you create a VI, you can use it on the Block Diagram of another VI."

I'd like to merge at least 2 PDF files into one while preserving all the form elements in the original PDFs. The form elements include text fields, radio buttons, check boxes, drop down menus and others. Please have a look at this sample PDF file with forms:
http://foersom.com/net/HowTo/data/OoPdfFormExample.pdf
Now try to merge it with any other arbitrary PDF file.
Can you do it?
EDIT: As for the implementation, I'd ideally prefer a command line solution on a linux plattform using open source tools such as 'ghostscript', or any other tool that you think is appropriate to solve this task.
Of course, everybody is welcome to supply any working solution to this problem, including a coded solution that involves writing a script which makes some API calls to a pdf-processing library. However, I'd suggest to take the path of least resistance first (CMD Solution).
Best Regards
EDIT #2: Well there are indeed several CMD tools that merge PDFs. However, these tools don't seem to, AFAIK, to preserve the forms in the original PDFs! These tools appear to simply just concatenate the printouts of all those PDFs into a single Printout, which is then presented as a single PDF.
Furthermore, If you printout a PDF file with forms into a file, you lose all the forms in it. This clearly not what I'm looking for.
I have found success using pdftk, which is an open-source software that runs on linux and can be called from your terminal.
To concatenate multiple pdfs into one (and preserve form-fillable elements), you can use the following command:
pdftk input1.pdf input2.pdf cat output output-file.pdf
I am using AutoCAD 2014 LT.
I have bought a library on AutoCAD which lets me insert blocks as slide very easily, through a CUI menu (ACADLT/Partial Customization/CustomLibrary/Menus).
I would like to add a slide file (which a already have).
From what I've been able to find online, I have to modify the macro, but the macro itself is really short:
$!=CustomLib-1.image_sub $!=* //Where sub changes depending on which submenu is selected
I understand the $ means its DIESEL language, but I do not understand the !, or what the image command means. I tried to go edit the CustomLib-1.CUI file in WordPad, but it clearly says I should modify it in AutoCAD through the CUI. I also have a CUIX file but I can't seem to open it, either in WordPad or AutoCAD.
I know I'm not missing much, but the last step is where I've been stuck for the past few days.
I'm still getting used to Matlab, and not sure if this is possible using Matlab or not, but it's just something that popped into my head that I thought could be interesting.
Is there any way to edit the contents of a text file in Matlab?
Moreover, is there any way to edit specific parts of the text file without altering the rest?
To elaborate, let's say I had a text file that was several lines long. For instance:
This is a hypothetical text file.
The cat chased a mouse.
The mouse ran into a hole.
The cat tried to paw at the mouse.
The mouse waited in the hole until the cat got bored.
The mouse came back out when the cat left.
Is there any way to use Matlab to exclusively edit, say, line 6 and change it from "The mouse waited in the hole until the cat got bored" to "The mouse fell asleep and the cat got bored", without having to change the rest of the file?
I know of several methods to read and display contents of text files using Matlab, but I'm not sure if there's any way to actually edit the text files in Matlab.
Thanks!
As far as I know, you will always have to read the file line by line (for instance into a cell-array) and edit it as you need. After that, you write a new file or overwrite the old one.
Of course, you can encapsulate this procedure and then call you own function like
manipulateFile(lineNumber, newLineText)
Some commands that may come in handy are fopen, fscanf, textread, fprintf, and fclose.
I was wondering if there's a way to allow a buffer to edit multiple files at once.
Recently, I got vim working with eclim. But now I was wondering if I could edit multiple files at once in one buffer. For example, say I have an interface and a class file where I need to update a method signature is there a way I can load both of them into the same buffer and edit them simultaneously. Narrow region for multiple file regions. It would also be awesome to remember my settings but that could be a future iteration.
I saw this solution but it seems inconvenient to create a separate file to handle this interaction.
You can open all files as split windows (so you see all of them together), and :windo, :bufdo, :argdo allow you to perform mass-operations (like a :substitute) on all of them at once. There's usually no need for such artificial concatenation schemes, and as the linked article shows, it has its downsides over keeping the files separate.
I want to log the running of my program, specifically the running time of each part. At this moment I print to the screen using disp. Is there a way so that some of the things I print would also be printed into a text file?
You can use the DIARY command, that captures everything from the command window.
There are other solutions to this problem where you write to one or more logfiles opened when your program is running. This provides a permanent record without polluting your work space or diary. It also works well if you compile your MATLAB application.
Jan Simon has a nice solution at MATLAB Central which uses a persistant file id so the log to file mechanism can be used again and again throughout an application with many functions without passing the file id about.
Others at MATLAB Central (here and here) have developed class based solutions with more features.
Also, fprintf.
