我一直在为一个Minecraft服务器的经理应用程序工作,当我运行我的程序时,控制台显示并消失,如果我手动运行它,它运行没有和问题。我的代码:
Process process = new Process
{
StartInfo =
{
FileName = textBox2.Text,
//Arguments = textBox3.Text,
UseShellExecute = false,
RedirectStandardOutput = true,
CreateNoWindow = false,
}
};
process.OutputDataReceived += new DataReceivedEventHandler(server_outputDataReceived);
server = process;
process.Start();
批处理文件代码(idk是什么语言的批处理文件,所以我使用默认语言 - 选择语言):
java -Xmx1024M -jar craftbukkit-1.7.2-R0.3.jar -o false
顺便说一句。你能在不创建文件的情况下启动进程(例如,启动进程“java -jar示例”,不创建文件)?
@Edit 回答第三个问题:Answer to the third question
我的完整代码(MessageBoxes是波兰语,因为我来自波兰,但后来我会添加对其他语言的支持):
using System;
using System.IO;
using System.Windows.Forms;
using System.Diagnostics;
namespace WindowsFormsApplication1
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
public Process server;
private Boolean runServer()
{
if (!File.Exists(textBox2.Text))
{
MessageBox.Show("Brak określonej ścieżki dostępu! (" + textBox2.Text + ")", "Błąd", MessageBoxButtons.OK, MessageBoxIcon.Error);
return false;
}
Process process = new Process
{
StartInfo =
{
FileName = textBox2.Text,
//Arguments = textBox3.Text,
UseShellExecute = false,
RedirectStandardOutput = true,
CreateNoWindow = false,
}
};
process.OutputDataReceived += new DataReceivedEventHandler(server_outputDataReceived);
process.ErrorDataReceived += new DataReceivedEventHandler(server_outputDataReceived);
server = process;
if (process.Start())
return true;
else
{
MessageBox.Show("Nie można włączyć serwera!", "Błąd", MessageBoxButtons.OK, MessageBoxIcon.Error);
return false;
}
}
private String ReadFile(String filename, int line)
{
StreamReader reader = new StreamReader(filename);
for (int i = 0; i < line; i++)
{
reader.ReadLine();
}
return reader.ReadLine();
}
private void ReloadOPs()
{
if (!File.Exists(textBox1.Text))
{
MessageBox.Show("Sciezka dostępu do pliku z listą graczy posiadających OP nie istnieje! (" + textBox1.Text + ")", "Błąd", MessageBoxButtons.OK, MessageBoxIcon.Exclamation);
tabControl1.SelectedTab = tabPageOptions;
textBox1.SelectAll();
return;
}
String line = ReadFile(textBox1.Text, 0);
comboBox1.Items.Clear();
for (int i = 1; i < File.ReadAllLines(textBox1.Text).Length; i++)
{
if (!String.IsNullOrWhiteSpace(ReadFile(textBox1.Text, i)))
{
comboBox1.Items.Add(line);
line = ReadFile(textBox1.Text, i);
}
}
MessageBox.Show("Lista graczy z OP, została odświeżona.");
}
// OPs combobox (OPs)
private void comboBox1_SelectedIndexChanged(object sender, EventArgs e)
{
groupBox1.Text = comboBox1.SelectedItem.ToString();
groupBox1.Visible = true;
}
private void Form1_Load(object sender, EventArgs e)
{
textBox1.Text = Application.StartupPath.ToString() + @"\ops.txt";
ReloadOPs();
}
// Reload OPs button (OPs)
private void button1_Click(object sender, EventArgs e)
{
ReloadOPs();
}
// Save button (Options)
private void button4_Click(object sender, EventArgs e)
{
}
private void server_outputDataReceived(object sender, DataReceivedEventArgs e)
{
addConsoleMessage(e.Data.ToString(), true);
}
// Run server button (Menu)
private void button5_Click(object sender, EventArgs e)
{
if (!runServer())
return;
server.BeginOutputReadLine();
button6.Enabled = true;
}
// Stop server button (Menu)
private void button6_Click(object sender, EventArgs e)
{
if(!server.HasExited)
server.Kill();
button6.Enabled = false;
}
private void addConsoleMessage(String message, Boolean refresh)
{
listBox1.Items.Add(message);
if (refresh)
listBox1.Refresh();
}
}
}
现在可以使用,但是在第二条消息后批处理文件返回(?)之后,程序崩溃,因为InvaildOperationException未处理。
答案 0 :(得分:0)
确定。让我们澄清一些观点。我假设您有一个名为filename.bat
的批处理文件,其中包含以下内容:
java -Xmx1024M -jar craftbukkit-1.7.2-R0.3.jar -o false
并使用&#34;手动运行&#34;您的意思是打开命令行窗口并输入:filename
。好?但是,您没有说明如何在不手动运行批处理文件时运行批处理文件!如果从文件浏览器中双击它,则缺少批处理文件以将当前目录更改为批处理文件所在的目录:
cd "%~P0"
java -Xmx1024M -jar craftbukkit-1.7.2-R0.3.jar -o false
PS - 您的批处理文件不应命名为start.bat
,因为start
是内部cmd.exe命令的名称!
