  • Can regular expressions be used to match nested patterns?

    - by Richard Dorman
    Is it possible to write a regular expression that matches a nested pattern that occurs an unknown number of times. For example, can a regular expression match an opening and closing brace when there are an unknown number of open closing braces nested within the outer braces. For example: public MyMethod() { if (test) { // More { } } // More { } } // End Should match: { if (test) { // More { } } // More { } }

  • Single console in eclipse for both Server and Client

    - by rits
    I am building a client server application using Java Sockets (in Windows XP). For that I need different consoles for both Client and Server(for Input and Output operations). But in eclipse both share a single console. Is there any plugin or some sort of cheat through which I can do this. After googling I got this, http://dev.eclipse.org/newslists/news.eclipse.newcomer/msg17138.html But, this seems to be only for write operations, not read operations. Also, I tried the following to launch application manually, but even this is not working........ package mypack; import java.io.BufferedOutputStream; import java.io.File; import java.io.FileOutputStream; import java.io.IOException; import java.io.OutputStream; import java.io.PrintStream; public class MySystem { public static void changeStream(String mainFile) throws IOException{ File temp = new File(".") ; String parentPath = temp.getCanonicalPath() ; System.out.println(parentPath); //creation of batch file starts here try{ File f = new File(parentPath + "\\a.bat") ; System.out.println("Created : " + f.createNewFile()); //f.deleteOnExit() ; FileOutputStream fos = new FileOutputStream(f) ; String str = "java " + mainFile ; String batchCommand="@echo off\n"+str+"\npause\nexit"; char arr[] = batchCommand.toCharArray() ; System.out.println(str) ; for(int i = 0 ; i < arr.length ; i++){ fos.write(arr[i]) ; } fos.close() ; } catch(Exception e){ } //creation of batch file ends here //execution of batch file starts here try{ Runtime r = Runtime.getRuntime() ; System.out.println(parentPath + "\\a.bat") ; Process p = r.exec(new String[]{"cmd","/k","start a.bat"},null,new File(parentPath)) ; OutputStream os = (OutputStream)p.getOutputStream() ; System.setOut( new PrintStream(os) ) ; System.out.println("Hello"); } catch(Exception e){ e.printStackTrace(); } //execution of batch file ends here } public static void main(String[] args) throws IOException { MySystem.changeStream("MySystem") ; } }

  • Writing a Virtual Printer in .NET

    - by David Osborn
    I'm looking to create a virtual printer that passes data to my .NET application. I want to then create an installer that installs both the printer and the .NET application. It would we really nice to be able to write it all in C#, but I have a feeling that this will require a printer driver to be written is unmanaged code. Does anyone know of a fairly clean tutorial or example of how to do this?

  • Generate SQL script to insert XML from files, using Powershell

    - by Jeff Meatball Yang
    I have a bunch of (50+) XML files in a directory that I would like to insert into a SQL server 2008 table. How can I create a SQL script from the command prompt or Powershell that will let me insert the files into a simple table with the following schema: XMLDataFiles ( xmlFileName varchar(255) , content xml ) All I need is for something to generate a script with a bunch of insert statements. Right now, I'm contemplating writing a silly little .NET console app to write the SQL script. Thanks.

  • jQuery test if element1 is child of element2

    - by Jake
    Does anyone know a good way to test if one element, stored in a var, is the child of another, also stored in a var? I don't need element1.isChildOf('selector'), that's easy. I need element1.isChildOf(element2) element2.find(element1).size() > 0 Does not seem to work. I don't want to have to write a plugin the uses .each to test each child if I can avoid it.

    - by Bob
    What is the preffered method for creating a byte array from an input stream? Here is my current solution with .NET 3.5. Is it still a better idea to read and write chunks of the stream? Stream s; byte[] b; using (BinaryReader br = new BinaryReader(s)) { b = br.ReadBytes(s.Length); }

  • create a text table with php using fixed width font

    - by Hintswen
    I want to write a PHP script to output some data as a plain-text table using spaces to get the data into columns (just like the Linux top command). I can't use a HTML table as the script output will be saved to disk and viewed in a plain-text editor. Is there anything available that can do this automatically (format the data into columns)?

  • Are vb.net eventArgs maintained at a "system" level?

    - by GregH
    I have a custom developed control I am using that somebody else wrote. For some reason, when the control was written, they did not write an event handler for the "mouseDown" event so when I mouseDown on the control, no event is fired. What I am basically trying to do is capture which mouse button (left or right) is pressed when the control is clicked on. Is there any sort of system level objects that maintain system state (including which mouse buttons are currently being pressed regardless of the control being clicked upon?)
