What "cscript //NoLogo" stands for?
提问by Sarsur.A
This is a java program code that runs the Notepad program and pastes a specific text stored in this program itself....
这是一个java程序代码，它运行记事本程序并粘贴存储在该程序本身中的特定文本....
I was wondering if you can explain me the String vbsvalue, and also the File file, and the ("cscript //NoLogo " + file.getPath())in the Process p.
If you are as generous, then please explain me the whole code.
我在想，如果你能解释一下我的String vbs价值，也File file和("cscript //NoLogo " + file.getPath())在Process p。如果你这么大方，那么请向我解释整个代码。
I'm a beginner in Java, well not exactly but if u wanna judge from 0 to 10 i would be 1.5/10
我是 Java 的初学者，不完全是，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();
}
}

Though this question wasn'tprimarily about cscript //NoLogo, regardless of its title, it still googles well for that phrase, so let's answer that in too much detail too.
虽然这个问题主要不是关于cscript //NoLogo，不管它的标题是什么，它仍然可以很好地搜索该短语，所以让我们也详细回答一下。
I'm not sure why they call it a "logo", but it's exactly what you might think from the built-in help @MByD displayed. But in the interest of over-completeness...
我不确定为什么他们称它为“徽标”，但这正是您从显示的内置帮助 @MByD 中可能想到的。但是为了过度完整性......

So if you're piping output and don't want all that Microsoft boilerplate, \\Nologo-ify it.
因此，如果您正在管道输出并且不想要所有 Microsoft 样板文件，\\Nologo请对其进行验证。

And, wow, that is a horribly convoluted way to get text into Notepad. I'm guessing it's more about teaching how to write to a file and execa command from Java, perhaps?
而且，哇，这是一种将文本输入记事本的极其复杂的方式。我猜这可能更多是关于教授如何exec从 Java写入文件和命令？

What you basically do is:
你基本上做的是：
- Create a String that contains a script (
String vbs = ...) - Write it to a file (
File file = File...tofw.close()) - Execute this script in a separate process by invoking cscript (
Process p = Runtime.getRuntime().exec(...))
- 创建一个包含脚本的字符串 (
String vbs = ...) - 将其写入文件 (
File file = File...tofw.close()) - 通过调用 cscript (
Process p = Runtime.getRuntime().exec(...))在单独的进程中执行此脚本
