问题 I store the path of my database (a folder with some xml files) in the app.config. At the startup I check, if the path exists. If it doesn't exist, I want to set the path to the default path. Code looks like this: public void CheckAndRepairSettings() { /* Check Paths */ if(GetDatabasePath() == null) SetDatabasePath(System.AppDomain.CurrentDomain.BaseDirectory + "DataBase"); } GetDatabasePath() reads the path form the app.config and SetDatabasePath() writes the path to the app.config. These

How to scan a file in a different directory in java?

由 馋奶兔 提交于 2020-01-14 14:59:10
问题 How do you scan a file with java that isn't in the directory the java file is in? For example: The java file is located at "C:\Files\JavaFiles\test.java" However, the file I want to scan is located at "C:\Data\DataPacket99\data.txt" Note: I've already tried putting another java file in the "C:\Data" directory and using the test.java file as a class, but it doesn't work. It still tries to scan from the "C:\Files\JavaFiles" Directory. 回答1: By using an absolute path instead of a relative. File

How does the Call Directory Extension in iOS get updated

由 不羁的心 提交于 2020-01-14 13:51:30
问题 I have an app that I'm developing and I want to store a few thousand phone numbers using the Call Directory Extension of CallKit. What I'm confused about is, how and when does the extension get called? It doesn't seem like it happens with every phone call. Does it happen whenever the app is started? The reason I'm asking, I don't want to keep the thousands of phone numbers in my app. I don't want the user to see these phone numbers (unless of course, they get a call from one of them). So,

问题 Is there a way to set a password for a folder programmatically? 回答1: The best solution I can think of is to do it like you do in java: An example in this link describes as follows: import java.io.*; import java.nio.channels.FileChannel; import java.nio.channels.FileLock; public class FileLockTest { public static void main(String[] args) throws Exception { RandomAccessFile file = null; FileLock fileLock = null; try { file = new RandomAccessFile("FileToBeLocked", "rw"); FileChannel fileChannel

Extract Directory Inside Zip

由 只愿长相守 提交于 2020-01-13 18:10:57
问题 I'm writing a script to extract files from a zip archive into the directory that the script is located. Here's my code: $zip = new ZipArchive; if ($zip->open('latest.zip') === TRUE) { $zip->extractTo('.'); $zip->close(); unlink('installer.php'); echo 'it works!'; } else { echo 'failed'; } This works fine, but there's one problem. The zip contains an extra layer. (zip/directory/files) which extracts like this directory/files rather then just the files. Is there a way to remove this extra layer

Safe way to remove a symbolic link to an non-existing directory (for the python binary)

由 若如初见. 提交于 2020-01-13 17:54:53
问题 I accidentally typed: sudo ln -sf /usr/local/bin/python2.5/ /usr/bin/python instead of: sudo ln -sf /usr/local/bin/python2.5 /usr/bin/python Now bash tells me that /usr/bin/python is not a directory whenever I run python. ls -l /usr/bin/python gives me expectedly /usr/bin/python --> /usr/local/bin/python2.5/ Is there any safe way to remove that symbolic link to a directory (that does not exist) and replace it with a link to the intended file? Arigato in advance if you have any ideas. I am

Python Module Importing Issues

由 天大地大妈咪最大 提交于 2020-01-13 16:55:29
问题 I run Windows 7, and I can import built-in modules, but when I save my own script and try to import it in IDLE, I get an error saying that the module doesn't exist.

However, whenever i type import module_name in IDLE, it says that the module doesn't exist. What am I doing wrong, or not doing? I've tried import
