这是一个java程序代码,它运行记事本程序并粘贴存储在此程序中的特定文本....

我想知道您是否可以向我解释String vbs值,File file以及("cscript //NoLogo " + file.getPath())中的Process p。 如果你是慷慨的,那么请解释整个代码。

我是Java的初学者,不完全如此,但如果你想从0到10判断我会是1.5 / 10

import java.io.File;
import java.io.FileWriter;
import javax.swing.JTextField;

 public class PasteToNotepad {

   public static void main(String[] args) throws Exception {
     String text = "Some text for testing.";
     JTextField textField = new JTextField(text);
     textField.setSelectionStart(0);
     textField.setSelectionEnd(text.length() - 1);
     textField.copy();

     String vbs = ""
             + "Set WshShell = WScript.CreateObject(\"WScript.Shell\")\n"
             + "WshShell.Run \"notepad\", 9\n"
             + "WScript.Sleep 500\n"
             + "WshShell.SendKeys \"^V\"";

     File file = File.createTempFile("PrintDialog", ".vbs");
     file.deleteOnExit();
     FileWriter fw = new java.io.FileWriter(file);
     fw.write(vbs);
     fw.close();
     Process p = Runtime.getRuntime().exec("cscript //NoLogo " + file.getPath());
     p.waitFor();
   }
 }

你基本上做的是:

  1. 创建包含脚本(String vbs = ...
  2. 的字符串
  3. 将其写入文件(File file = File...fw.close()
  4. 通过调用cscript(Process p = Runtime.getRuntime().exec(...)
  5. 在单独的进程中执行此脚本

    关于cscript //NoLogo,这几乎与Java无关,这是一个Windows命令:

    C:\Documents and Settings\bsharet>cscript
    Microsoft (R) Windows Script Host Version 5.7

    Usage: CScript scriptname.extension [option...] [arguments...]
    
    Options:
     //B         Batch mode: Suppresses script errors and prompts from displaying
     //D         Enable Active Debugging
     //E:engine  Use engine for executing script
     //H:CScript Changes the default script host to CScript.exe
     //H:WScript Changes the default script host to WScript.exe (default)
     //I         Interactive mode (default, opposite of //B)
     //Job:xxxx  Execute a WSF job
     //Logo      Display logo (default)
     //Nologo    Prevent logo display: No banner will be shown at execution time
     //S         Save current command line options for this user
     //T:nn      Time out in seconds:  Maximum time a script is permitted to run
     //X         Execute script in debugger
     //U         Use Unicode for redirected I/O from the console

虽然这个问题主要不是cscript //NoLogo,但无论其标题如何,它仍然适用于该短语,所以让我们回答过多细节也是。

我不确定为什么他们称之为"徽标",但它正是您可能从内置帮助@MByD显示的内容。但是为了过度完整......

C:\prompt>cscript spam.js

C:\prompt>cscript //NoLogo spam.js

C:\prompt>

因此,如果您需要管道输出并且不想要所有Microsoft样板文件,\\Nologo - ify it。

C:\prompt>cscript spam.js > out.txt

C:\prompt>more out.txt

C:\prompt>cscript spam.js //NoLogo > out.txt

C:\prompt>more out.txt

C:\prompt>

spam.js中有var spam = "spam";。)

而且,哇,这是一种将文本输入记事本的可怕方式。我猜它更多的是教授如何写一个文件和exec来自Java的命令,或许?
