  • File Uploads with Turbogears 2

    - by William Chambers
    I've been trying to work out the 'best practices' way to manage file uploads with Turbogears 2 and have thus far not really found any examples. I've figured out a way to actually upload the file, but I'm not sure how reliable it us. Also, what would be a good way to get the uploaded files name? file = request.POST['file'] permanent_file = open(os.path.join(asset_dirname, file.filename.lstrip(os.sep)), 'w') shutil.copyfileobj(file.file, permanent_file) file.file.close() this_file = self.request.params["file"].filename permanent_file.close() So assuming I'm understanding correctly, would something like this avoid the core 'naming' problem? id = UUID. file = request.POST['file'] permanent_file = open(os.path.join(asset_dirname, id.lstrip(os.sep)), 'w') shutil.copyfileobj(file.file, permanent_file) file.file.close() this_file = file.filename permanent_file.close()

  • 'Programming by Coincidence' Excercise: Java File Writer

    - by Tapas
    I just read the article Programming by Coincidence. At the end of the page there are excercises. A few code fragments that are cases of "programming by coincidence". But I cant figure out the error in this piece: This code comes from a general-purpose Java tracing suite. The function writes a string to a log file. It passes its unit test, but fails when one of the Web developers uses it. What coincidence does it rely on? public static void debug(String s) throws IOException { FileWriter fw = new FileWriter("debug.log", true); fw.write(s); fw.flush(); fw.close(); } What is wrong about this?

  • File Encoding handling in Eclipse 3.5

    - by Cédric Girard
    Hi, I use Eclipse 3.5 on Windows, with PDT and Subclipse plugins, with both legacy projects using ISO-8859-1 encoding (latin-1), and newers ones wich use UTF-8. I configured my workspace to use UTF-8, and I configured old projects to use latin-1. But every time I open an old project, it use UTF-8. With a workspace using latin-1 by default, I have the same problem with utf-8 projects edited as iso-8859-1. My encoding choice is written in the file .settings/org.eclipse.core.resources.prefs but seems to be never read. The only solution for now is to have a latin1 workspace, and an utf8 one. Any better idea? Regards, Cédric

  • Caching web page data, Database or File

    - by Mahdi
    I am creating an RSS reader application that requests the RSS from my server. I mean, the RSS is first downloaded to my server, then application downloads it from my server. I want to create RSS cache for this. And for example, each RSS would be refreshed every 1 minute. So, If 10 users request RSS of example.com in 1 minute, my server will download it only for the first time, and in other 9 requests, RSS will be loaded from cache. My question is, Should I use a Database (MSSQL) for this purpose? or I should use files? I have no limit in Database size nor in file size... EDIT: I'm using ASP.NET for the server.

  • Packing a file into an ELF executable

    - by Pierre Bourdon
    Hello, I'm currently looking for a way to add data to an already compiled ELF executable, i.e. embedding a file into the executable without recompiling it. I could easily do that by using cat myexe mydata > myexe_with_mydata, but I couldn't access the data from the executable because I don't know the size of the original executable. Does anyone have an idea of how I could implement this ? I thought of adding a section to the executable or using a special marker (0xBADBEEFC0FFEE for example) to detect the beginning of the data in the executable, but I do not know if there is a more beautiful way to do it. Thanks in advance.

  • Invoke Java via Batch File with Filepath Arguments

    - by EricIdyll
    Hi there, I'm having an issue getting files loaded into an app called GCS, by dragging them onto the executable. GCS can be invoked on Windows with a bat file, which goes like this: @echo off start javaw -Xmx256M -jar "GURPS Character Sheet.app/Contents/Resources/Java/GCS.jar" %* If I hard code a filepath in place of the batch argument wildcard (with quotes), it works. If I run the debugger with a filepath argument it works. If I echo %, it gives me the correct filename with quotes around it. If I add quotes around % it still breaks. I have a disconnect here between DOS and Java, and I'm at a loss. Does anyone recognize this problem? Thanks in advance.

  • Add bytes to binary file using only PHP?

    - by hurmans
    I am trying to add random bytes to binary (.exe) files to increase it size using php. So far I got this: function junk($bs) { // string length: 256 chars $tmp = 'aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa'; for($i=0;$i<=$bs;$i++) { $tmp = $tmp . $tmp; } return $tmp; } $fp = fopen('test.exe', 'ab'); fwrite($fp, junk(1)); fclose($fp); This works fine and the resulting exe is functional but if I want to do junk(100) to add more size to the file I get the php error "Fatal error: Allowed memory size..." In which other way could I achieve this without getting an error? Would it be ok to loop the fwrite xxx times?

  • Prevent batch file in CMD from closing without using Pause

    - by Bondye
    Currently I want to run a batch file that fires a command and show me that log. After that I need to be able to commit and view the status so this prompt may not disappear after a key press. I've searched the net and the only answer people have is pause which close the prompt after a keypress. Does anyone have the solution for me? Currently I made a shortcut to cmd.exe and made the target my folder, but I want to execute some commands also. Thanks in advance.

  • Add HTML Id's to tags in .aspx file

    - by slandau
    So I'm writing an app that lets the user select a folder, it gets all the .aspx files in that folder, and lets the users check off which ones they want to add HTML ID's to. Then they click start, and this runs private void btnStart_Click(object sender, EventArgs e) { for (int i = 0; i < listFiles.CheckedItems.Count; i++) { } } It loops through all the selected file names. How do I open each of these .aspx files in the background, and go through them and add the id="thisItemId" attribute to each tag that's like a , , , , , etc....

  • File listing application on Windows : what language ?

    - by Studer
    I need to create a simple application/script able to list the hierarchy of a folder containing subfolders and files (mostly PDF), so that a user can browse easily these files and maybe have a quick preview of them. The files are all on an internal file server, so the dynamic aspects should all be client-sided. My goal (and what my boss want) is to provide some sort of an HTML page listing, to have something like this. The only problem I have now is that I cannot install anything on computers, so I cannot use PHP, Python, ... This application will only runs on Windows in Internet Explorer. What are the different possibilities I have ? I don't know if I can do this but I was thinking of using HTML + Flex. Thanks for helping.

  • Foreach File in a Folder in Flash?

    - by msandbot
    Hey, I have an image slideshow program working right now and it takes in a folder of a hard coded in number of images. I would like to change this so that it can take in a folder and will display all of them no matter the number. Is there a way to do this in flash? I'm thinking something like the foreach loop in perl or other scripting language. It is possible to store then number of images in a text file but I also don't know how to read that in flash either. I'm working in actionscript 3. Any help would be greatly appreciated. Thanks -Mike

  • Batch file writing to log then ending process

    - by Andrew Service
    I have a batch file that calls a process and in that process I have: IF %ERRORLEVEL% NEQ 0 EXIT /B %ERRORLEVEL% Now I wanted to upgrade this a bit and give some meaningful message to an output log when if the process fails, also I do not want the main batch to continue processing because the next processes are dependent on data from previous calls; I wonder if this would be correct but not sure: CALL Process 1 IF %ERRORLEVEL% NEQ 0 GOTO ErrorInfirstProcess /B %ERRORLEVEL% :ErrorInfirstProcess ECHO Process 1 Failed on %Date% at %Time%. >>C:\Log.txt" CALL Process 2 IF %ERRORLEVEL% NEQ 0 GOTO ErrorInSecondProcess /B %ERRORLEVEL% :ErrorInSecondProcess ECHO Process 2 Failed on %Date% at %Time%. >>C:\Log.txt" I also want to know if I still need the /B or do I need to put an EXIT command after the echo? Thanks A

  • Python .app doesn't read .txt file like it should

    - by Bambo
    This question relates to this one: Python app which reads and writes into its current working directory as a .app/exe i got the path to the .txt file fine however now when i try to open it and read the contents it seems that it doesn't extract the data properly. Here's my code - http://pastie.org/4876896 These are the errors i'm getting: 30/09/2012 10:28:49.103 [0x0-0x4e04e].org.pythonmac.unspecified.main: for index, item in enumerate( lines ): # iterate through lines 30/09/2012 10:28:49.103 [0x0-0x4e04e].org.pythonmac.unspecified.main: TypeError: 'NoneType' object is not iterable I kind of understand what the errors mean however i'm not sure why they are being flagged up because if i run my script with it not in a .app form it doesn't get these errors and extracts the data fine.

  • Live Mesh has screwed up my file permissions

    - by Jason
    I got the bright idea of using Live Mesh to sync up my development directories between my laptop and desktop machines. It appears that the permission on any new files that are added through Live Mesh do not inherit permissions from the parent directory. Now I cannot overwrite the permissions on those files. I keep getting an "Access is Denied" error when attempting to do so, even if I am running Windows Explorer as administrator. I have two questions: How can I modify the file permissions to allow them to inherit again? Has anyone used Live Mesh to do this sort of thing? Or should I be using FolderShare instead?

  • How to save multiple UIImage to a file iPad

    - by aron
    I have a PDF reader that displays pages of the document. What I want to do is allow the user to draw over the PDF in a transparent view. Then I want to save the drawing (UIImage) to disk. If at all possible, I don't want to have the documents folder filled with files like documentName_page01.png, documentName_page02.png for every page that is drawn over. However, I can't figure out how to store these UIImages into a single file without it becoming unwieldy and memory intensive. Any ideas appreciated.

  • When to define SDD(System Sequence Diagram) operations System->Actor?

    - by devoured elysium
    I am having some trouble understanding how to make System Sequence Diagrams, as I don't fully grasp why in some cases one should define operations for System - Actor and in others don't. Here is an example: Let's assume the System is a Cinema Ticket Store and the Actor is a client that wants to buy a ticket. 1) The User tells the System that wants to buy some tickets, stating his client number. 2) The System confirms that the given client number is valid. 3) The User tells the System the movie that wants to see. 4) The System shows the set of available sessions and seats for that movie. 5) The System asks the user which session/seat he wants. 6) The User tells the System the chosen session/seat. This would be converted to: a) -----> tellClientNumber(clientNumber) b) <----- validClientNumber c) -----> tellMovieToSee(movie) d) <----- showsAvailableSeatsHours e) -----> tellSystemChosenSessionSeat(session, seat) I know that when we are dealing with SDD's we are still far away from coding. But I can't help trying to imagine how it how it would have been had I to convert it right away to code: I can understand 1) and 2). It's like if it was a C#/Java method with the following signature: boolean tellClientNumber(clientNumber) so I put both on the SDD. Then, we have the pair 3) 4). I can imagine that as something as: SomeDataStructureThatHoldsAvailableSessionsSeats tellSystemMovieToSee(movie) Now, the problem: From what I've come to understand, my lecturer says that we shouldn't make an operation on the SDD for 5) as we should only show operations from the Actor to the System and when the System is either presenting us data (as in c)) or validating sent data (such as in b)). I find this odd, as if I try to imagine this like a DOS app where you have to put your input sequencially, it makes sense to make an arrow even for 5). Why is this wrong? How should I try to visualize this? Thanks

  • Passing System classes as constructor parameters

    - by mcl
    This is probably crazy. I want to take the idea of Dependency Injection to extremes. I have isolated all System.IO-related behavior into a single class so that I can mock that class in my other classes and thereby relieve my larger suite of unit tests of the burden of worrying about the actual file system. But the File IO class I end up with can only be tested with integration tests, which-- of course-- introduces complexity I don't really want to deal with when all I really want to do is make sure my FileIO class calls the correct System.IO stuff. I don't need to integration test System.IO. My FileIO class is doing more than simply wrapping System.IO functions, every now and then it does contain some logic (maybe this is the problem?). So what I'd like is to be able to test my File IO class to ensure that it makes the correct system calls by mocking the System.IO classes themselves. Ideally this would be as easy as having a constructor like so: public FileIO( System.IO.Directory directory, System.IO.File file, System.IO.FileStream fileStream ) { this.Directory = directory; this.File = file; this.FileStream = fileStream; } And then calling in methods like: public GetFilesInFolder(string folderPath) { return this.Directory.GetFiles(folderPath) } But this doesn't fly since the System.IO classes in question are static classes. As far as I can tell they can neither be instantiated in this way or subclassed for the purposes of mocking.
