I am creating a Flowgear workflow that needs to process a raft of XML data.
I have the xml data contained in a set of .xml files (approximately 400 files) in a folder on my local machine hard-drive and I want to read them into a workflow, run an XSLT transform and then write out the resultant XML to another folder on the same local hard-drive.
How do I get the flowgear workflow to read these files?
It depends on the use case, the File Enumerator works exceptionally well to loop (as in for-each) through each file. Sometimes, one wants to get a list of files in a particular folder and check whether a file has been found or not. For this, I would recommend a c# script to get a list of files with code:
Directory.GetFiles(#"{FilePath}", "*.{extension}", SearchOption.TopDirectoryOnly);
Further on, use the File node to read, write, or delete files from a file directory.
NB! You will need to install a DropPoint on the PC/Server to allow access to the files. For more information regarding Drop Points, please click here
You can use a File Enumerator or File Watcher to read the files up. The difference is that a File Enumerator will enumerate all files in a folder once, the File Watcher will watch a folder indefinitely and provide new files to the workflow as they are copied into the folder.
You can then use the File node to write the files back the the file system.

I have 3 xml file to be written to a folder for client. while writing the 2 files got written perfectly but 3rd file failed. what are the ways by which I can prevent the client to open any file or all the files got deleted or locked if anything failed?
If your application has delete privileges on the system, keep a record of the filenames to the files you're writing. If a file fails for whatever reason, go through the list of file names and delete the files from the directory. A simple string list with a for loop should do it.
How can I use the "Download File" component to only download new files or files that have been updated remotely?
Consider a graph like the following:
where File Download is defined as:
I have many *.csv files in ${S3_OR_DATA_DIR_LOCATION}; I'm adding one every day).
How can I make sure GoodData only downloads new files AND files that have been updated? Would making the option "Overwrite existing files" False do it? Or would that only download new files and not update existing files that have been updated?
The File Download CloudConnect component by itself does not support action as downloading only a new file(s), which appeared in the source folder as it does not have any previous state remembering mechanism implemented, but as it has input port, it is possible to implement such mechanism yourself with using of File List CloudConnect component with a little help of Reformat, some Joiner and CSV Writer CloudConnect components. This way you can determine the content of the source folder and write it there in a plain text file. The mechanism can be designed the way, that the next processing would read the state file from the previous run and determine, what a new files are and then sends a list of a new files to the File Download CloudConnect component’s input port.
The another way how to process only a new files, which is way simpler then the process described in the previous article and therefore commonly used, is based on taking advantage of folder structures in the source folder, where there would be a dedicated folder for a new files and another dedicated folder for already processed files. The CloudConnect ETL process itself would then read a new files from its dedicated source folder and the last stage of the ETL process would contain File Copy/Move CloudConnect component used for transferring of the already processed new files from its dedicated folder to folder containing all already processed files.
I need to store files in an EXE file via VB 2010 app. I mean, lets say I made a software called setmaker and one that is called setup.exe. I want setmaker to store some files that you choose in setup.exe, and then when you run setup.exe it reads the files that you stored in it and extracts it to a location specified by you.
The following post How to copy file From Resources? discusses a method for copying a file that is an Embedded resource in an EXE to a folder on disk.
Hope that helps.
I checked quite a few similar questions, but so far I am unsatisfied with the solutions.
Ever use the Minecraft Server? At initial launch, it creates all the files and folders it needs, and allows you to make changes to files like Server.properties and ops.txt by making them external of the executable jar file.
I'm working on a similar project, and I want to duplicate that behavior. Everything works great when I run it in eclipse. When I export to a jar file though, things get funky. The external files and folders are created without a hitch, but afterword, it would appear as though they cannot be read from or written to. Any ideas how Notch made his server?
--edit--
Scratch that, it doesn't even appear to reliably create the files and folders. Maybe it only creates them the very first run after creation?
--edit again--
It creates them in the root directory. When I tested it in eclipse, the root directory was limited to the folder containing the project, and therefore looked fine. The solution was to make the class aware of it's location, and include it in all file operations.
Have the main class in your executable jar file look up where it is, then have it store that information in a global String or something. Prefix your filenames with that string in your file operations, and voila! It's writing to the correct directory.
I have added some files that I need to be downloaded to the Application start up path. So I set Build Action as content now the files have been copied some where
C:\Documents and Settings\TestUser.ANNAM\Local Settings\Apps\2.0\Data\HVDRBMY5.8AA\858AT9VM.TNP\test..tion_2d7cfc137d9c2c74_0001.0013_432bd4561850d290\Data
How can access file from the application. My problem since it is a dynamic path will it be same folder count so that we can use like ..\..\Data\ Some think like this
Application.UserAppDataPath gets the path for the application data of a user.
Application.StartupPath gives you the path for the executable file that started the application, not including the executable name.
Starting with one of these, you should be able to use System.IO to manipulate the paths until you get the folder where your data files are.
