[英]C# Batch file output problems
I have been working on a manager application for a Minecraft server, when I run my program, the console shows and disappears, if I run it manually, it runs without and problems. 我一直在为Minecraft服务器开发管理器应用程序,当我运行程序时,控制台会显示并消失,如果我手动运行它,则它会运行而不会出现问题。 Batch file code:
批处理文件代码:
java -Xmx1024M -jar craftbukkit-1.7.2-R0.3.jar -o false
My full code (MessageBoxes are in Polish, becouse im from Poland, but later i will add support for other languages): 我的完整代码(MessageBoxes是波兰语,因为来自波兰的im,但稍后我将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();
}
}
}
My problem is that program crashes becouse InvaildOperationException was unhandled (listBox1.Items.Add(message) in addConsoleMessage). 我的问题是,由于未处理InvaildOperationException(addConsoleMessage中的listBox1.Items.Add(message)),程序崩溃了。 External error information: Invalid operation between threads: the control 'listBox1' is accessed from a thread other than the thread it was created.
外部错误信息:线程之间的无效操作:控件'listBox1'是从创建线程之外的线程访问的。
You cannot update UI form background thread. 您无法更新UI表单背景线程。 Try this
尝试这个
WPF WPF
private void server_outputDataReceived(object sender, DataReceivedEventArgs e)
{
Dispatcher.CurrentDispatcher.Invoke(DispatcherPriority.Normal, () =>
{
addConsoleMessage(e.Data.ToString(), true);
});
}
Update 更新资料
In WinForms the Invoke/BeginInvoke
methods are directly on the control objects as you can see from the docs of System.Windows.Forms.Control . 在WinForms中,
Invoke/BeginInvoke
方法直接位于控件对象上,如您从System.Windows.Forms.Control的文档中所见。 So you'd have listBox1.BeginInvoke(...) for example. 因此,您将拥有例如listBox1.BeginInvoke(...)。
