I want to add a Run Script Phase to my Build Phases to call a swift executable that takes a plist file from my project and uses it to generate a swift file with some boilerplate code.
I figured out how to specify the input file for the Run Script Phase like this:
$(SRCROOT)/MyProject/MyData.plist
But for output files, Xcode gives me this $(DERIVED_FILE_DIR)/newOutputFile default value which, if I echo it via echo "$SCRIPT_OUTPUT_FILE_0", prints some strange path to the ....MyProject.build/DerivedSources folder. What is that? What do I do with this and how can I generate my output swift file and place it inside my project?
I don't really find much information about this $(DERIVED_FILE_DIR) (at least nothing that I understand, I've never worked with these things before).
Thanks!
Presumably the derived file directory is just a safe place to write output results to. It isn't in the project directory, but it is unique to the project.
However, you do want to write directly into the project directory (I presume), so just go ahead and do so, using the environmental variable PROJECT_DIR.
Is it possible include arbitrary files (in this case a .csv) from a TwinCAT project direct to the Boot directory of a PLC?
By using PATH_BOOTPATH in the file open/read FBs it is possible to load files from this directory in a convenient manner regardless of whether using a CE or Windows deployment, However deployment of files to this location seems to be the sticking point.
I know that a copy of the project code is included within the CurrentConfig<Project>.tpzip file, but this file is not easily accessible from code, or updateable.
I've found the 'Additional Files' section within the system configuration, but it makes little sense.
Adding a file from inside the project as a 'Relative' path doesn't seem to do anything
Adding a file from inside the project as an external path includes the file (via symbolic links?) in the 'CurrentConfig.tszip' file, which has the same issues as the .tpzip
Adding an external file as an external path again includes the file inside of the .tszip.
I'm willing to accept that this might not be possible, but it just feels odd that the PATH_BOOTPRJ and PATH_BOOTPATH roots are there and not accessing useful paths.
Deployment
To quote Beckhoff:
Deployment is used to set up commands that are to be executed during the installation and startup of an application.
The event types are essentially at what stage of the deployment process the command is performed, where the command can either be copying a file or execution of a script/program.
Haven't performed extensive testing but between absolute/relative pathing and execution this should solve nearly all issues with deployment configuration.

I have a DLL file and I want to execute it on Windows. I obtained this DLL file from a challenge site which alleges the DLL should be executed independently.
To run the functions in a DLL, first find out what those functions are using any PE (Portable Executable) analysis program (e.g. Dependency Walker).
Then use RUNDLL32.EXE with this syntax:
RUNDLL32.EXE <dllname>,<entrypoint> <optional arguments>
dllname is the path and name of your dll file, entrypoint is the function name, and optional arguments are the function arguments
You can execute a function defined in a DLL file by using the rundll command. You can explore the functions available by using Dependency Walker.
While many people have pointed out that you can't execute dlls directly and should use rundll32.exe to execute exported functions instead, here is a screenshot of an actual dll file running just like an executable:
While you cannot run dll files directly, I suspect it is possible to run them from another process using a WinAPI function CreateProcess:
https://msdn.microsoft.com/en-us/library/windows/desktop/ms682425(v=vs.85).aspx
DLLs are shared libraries which are used by other windows programs while EXEs are the files which are actually executed and are linked to DLL files so that they can use DLLs. Both are of same format, PE(portable executable or format of machine code in windows in simple words).
In other words EXEs contain the entry point(main) and the DLLs contain the library functions.. You cannot execute a file which just contains library functions you can just use them via other programs.
But still there are programs like rundll32.exe which provides that entry point and some minimal framework required by DLL functions to be called.
The point that I want to make is, you can never execute a DLL file you can just use it's code by providing an entry point through an EXE or some other program.
You can't "execute" a DLL. You can execute functions within the DLL, as explained in the other answers. Although .EXE files and .DLL files are essentially identical in terms of format, the distinguishing feature of an .EXE is that it contains a designated "entry point" to go and do the thing the EXE was created to do. DLLs actually have something similar, but the purpose of the "dll main" is just to perform initialization and not fulfill the primary purpose of the DLL; that is for the (presumably) various other functions it contains.
You can execute any of the functions exported by a DLL, assuming you know which one you want to execute; an EXE may contain a whole lot of functions, but one and only one is specially designated to be executed simply by "running" it.
To Run a .dll file..First find out what are functions it is exporting..Dll files will excecute
the functions specified in the Export Category..To know what function it is Exporting refer "filealyzer"
Application..It will show you the export function under "PE EXPORT" Category..Notedown the
function name--
Then open the command prompt,Type Rundll32 dllname,functionname
(dllname--name of your dll)
(Functionname-- name of the function you found under the PE Export)
Note:Makesure that your command prompt location is your dll file location
It should be mentioned that since it is entirely possible to run DLL's just as any other executable, it has long been considered a security issue. As such, there have been a number of security improvements and registry hacks (sorry no longer have ref-links) that prevents running DLL's from regular user space without extra privileges.
As a good example. I recall making these hacks, but since I no longer remember what exactly I did. I can no longer run any DLLs from normal user shell environment, even though starting various Win apps from GUI works just fine.
That said, one should definitely read "Dynamic-Link Library Security" and "Best Practices to Prevent DLL Hijacking".
.DLL files are not executable in the sense that .EXE/.COM/.BAT files are executable, so I'm not sure what you mean.
You can use the Dependency Walker application that comes with the Windows SDK to interrogate a .DLL and see what functions are exported by the file.
The following series of steps might be helpful:
Open Windows Explorer
In the top-left corner, click "Organize"
select "Folder and Search Options"
Switch to the "View" tab
Scroll down and uncheck "Hide file extensions for known file types"
Click OK
Now find the dll file
Right-click on it and select "Rename"
Change the extension(what comes after the last .) and change it to .exe
A little background
I'm working on a project that requires me to use an old (from 2006) large system of MatLab scripts. The script exists in an archive folder on a cluster but I need it to run fully from my cluster folder. I've got it mostly running from my personal folder but not entirely. It runs perfectly but there is a Python script that is called somewhere that doesn't exist in my personal directory.
What I want to do
Since the MatLab code I'm running includes many different script files, which themselves call even more script files, poring through them to find information about the Python script would be very very time consuming.
Therefore, I would like to be able to tell MatLab to not go to specific folders when calling a script, but instead, return an error. For example, if a scripted is called in the directory /notmyfolder, I want it to return an error.
Is this possible?
I am currently coding with Eclipse PDT, and I need to synchronise the files on my workstation with the files on the FTP server.
I've installed RSE, but I can only download and edit files as far as I can see it. What I want to happen is when I hit save, the file is saved locally, and the file to be updated on the FTP site.
Any ideas of how I can achieve this?
Create an ant builder on your project. See this article about how to do that. The important things you should know after you read the article:
You can use Ant FTP task to
transfer the files.
You can define properties given by
the Eclipse platform to get project
root, list of changed files, change
type (add, modify, delete) and so on.
Use them wisely. You will need
project_loc, resource_loc and so on.
See picture at end to see how to get
other available variables that can be
passed to the script.
Tune your Ant script, since if it run
for each file update, then it can be
slow. If it is slow anyway, then you can create a builder plugin for eclipse, which is not so complicated. I created some before.
Be prepared, that ant script can get
not only one file as changed, but a
list.
