  • String replace for personalize code generator

    - by Xurxof
    I must do a automatic codes generator with user-configurable string with predefined keys and can not find a good way to do it. For example, a string OT-{CustomCode}-{Date}-{##} could generate codes OT-C0001-20100420-01 OT-C0001-20100420-02 I thought of using RegExpr.Replace(), but I would have problems if the code of a customer was {##} Any help is welcome! (and sorry for my english)

  • pass string or data of local file between viewcontrollers

    - by Jonathan
    In my last question i asked how to best send a string from one view controller to another, both which were on a navigation stack: http://stackoverflow.com/questions/2898860/pass-string-from-tableviewcontroller-to-viewcontroller-in-navigation-stack However I just realised I can either pass the path to the file in the app's document's folder as the first (the table view) has already accessed the data in the file should I pass viewcontroller the data to the pushed VC?

  • In String.replace("\c","") what ASCII value is ""?

    - by Tom
    Hi, im just writing my own replace method for any weird characters and i used the ASCI value 0, null to replace unwanted characters, i was hoping for them to be 'deleted', but this doesnt work. A gap just appears in the string. What exactly does String.Replace() do when removing a character for ""? Does it shift them all down and then 'delete' the final character or something?

  • Why string.Replace("X","Y") works only when assigned to new string?

    - by Petr
    Hi, I guess it has to do something with string being a reference type but I dont get why simply string.Replace("X","Y") does not work? Why I need to do `string A=stringB.Replace("X","Y") I thought it is just a method to be done on specified instance? Thanks for explanation EDIT: Thank you so far. I extend my question Why "b+="FFF"works but the b.replace is not?

  • Convert list of dicts to string

    - by John
    I'm very new to Python, so forgive me if this is easier than it seems to me. I'm being presented with a list of dicts as follows: [{'directMember': 'true', 'memberType': 'User', 'memberId': '[email protected]'}, {'directMember': 'true', 'memberType': 'User', 'memberId': '[email protected]'}, {'directMember': 'true', 'memberType': 'User', 'memberId': '[email protected]'}] I would like to generate a simple string of memberIds, such as [email protected], [email protected], [email protected] but every method of converting a list to a string that I have tried fails because dicts are involved. Any advice?

  • java: how to compress data into a String and uncompress data from the String

    - by Guillaume
    I want to put some compressed data into a remote repository. To put data on this repository I can only use a method that take the name of the resource and its content as a String. (like data.txt + "hello world"). The repository is moking a filesystem but is not, so I can not use File directly. I want to be able to do the following: client send to server a file 'data.txt' server compress 'data.txt' into data.zip server send to repository content of data.zip repository store data.zip client download from repository data.zip and his able to open it with its favorite zip tool I have tried a lots of compressing example found on the web but each time a send the data to the repository, my resulting zip file is corrupted. Here is a sample class, using the zip*stream and that emulate the repository showcasing my problem. The created zip file is working, but after its 'serialization' it's get corrupted. (the sample class use jakarta commons.io ) Many thanks for your help. package zip; import java.io.File; import java.io.FileInputStream; import java.io.FileOutputStream; import java.io.IOException; import java.io.InputStream; import java.util.zip.ZipEntry; import java.util.zip.ZipInputStream; import java.util.zip.ZipOutputStream; import org.apache.commons.io.FileUtils; /** * Date: May 19, 2010 - 6:13:07 PM * * @author Guillaume AME. */ public class ZipMe { public static void addOrUpdate(File zipFile, File ... files) throws IOException { File tempFile = File.createTempFile(zipFile.getName(), null); // delete it, otherwise you cannot rename your existing zip to it. tempFile.delete(); boolean renameOk = zipFile.renameTo(tempFile); if (!renameOk) { throw new RuntimeException("could not rename the file " + zipFile.getAbsolutePath() + " to " + tempFile.getAbsolutePath()); } byte[] buf = new byte[1024]; ZipInputStream zin = new ZipInputStream(new FileInputStream(tempFile)); ZipOutputStream out = new ZipOutputStream(new FileOutputStream(zipFile)); ZipEntry entry = zin.getNextEntry(); while (entry != null) { String name = entry.getName(); boolean notInFiles = true; for (File f : files) { if (f.getName().equals(name)) { notInFiles = false; break; } } if (notInFiles) { // Add ZIP entry to output stream. out.putNextEntry(new ZipEntry(name)); // Transfer bytes from the ZIP file to the output file int len; while ((len = zin.read(buf)) > 0) { out.write(buf, 0, len); } } entry = zin.getNextEntry(); } // Close the streams zin.close(); // Compress the files if (files != null) { for (File file : files) { InputStream in = new FileInputStream(file); // Add ZIP entry to output stream. out.putNextEntry(new ZipEntry(file.getName())); // Transfer bytes from the file to the ZIP file int len; while ((len = in.read(buf)) > 0) { out.write(buf, 0, len); } // Complete the entry out.closeEntry(); in.close(); } // Complete the ZIP file } tempFile.delete(); out.close(); } public static void main(String[] args) throws IOException { final String zipArchivePath = "c:/temp/archive.zip"; final String tempFilePath = "c:/temp/data.txt"; final String resultZipFile = "c:/temp/resultingArchive.zip"; File zipArchive = new File(zipArchivePath); FileUtils.touch(zipArchive); File tempFile = new File(tempFilePath); FileUtils.writeStringToFile(tempFile, "hello world"); addOrUpdate(zipArchive, tempFile); //archive.zip exists and contains a compressed data.txt that can be read using winrar //now simulate writing of the zip into a in memory cache String archiveText = FileUtils.readFileToString(zipArchive); FileUtils.writeStringToFile(new File(resultZipFile), archiveText); //resultingArchive.zip exists, contains a compressed data.txt, but it can not //be read using winrar: CRC failed in data.txt.
