如何在程序中友好提示错误

昨天装配脑袋在交流会上讲了2005的新功能可以友好定义错误提示，我们也可以在vs2002/3中实现(所有代码参考sharpdevelop)http://www.icsharpcode.net

1.定义一个静态函数

static void ShowErrorBox(object sender, ThreadExceptionEventArgs eargs)

{

DialogResult result = new ExceptionBox(eargs.Exception).ShowDialog();

switch (result)

{

case DialogResult.Ignore:

break;

case DialogResult.Abort:

Application.Exit();

break;

case DialogResult.Yes:

break;

}

2.程序启动之前：

Application.ThreadException += new ThreadExceptionEventHandler(ShowErrorBox);

3.最后是ExceptionBox的定义

using System;

using System.Windows.Forms;

using System.Diagnostics;

using System.Resources;

using System.Reflection;

using System.Drawing;

namespace Auspe.Report.Common.Gui.Dialogs

{

public class ExceptionBox : System.Windows.Forms.Form

{

private System.Windows.Forms.TextBox exceptionTextBox;

private System.Windows.Forms.CheckBox copyErrorCheckBox;

private System.Windows.Forms.CheckBox includeSysInfoCheckBox;

private System.Windows.Forms.Label label3;

private System.Windows.Forms.Label label2;

private System.Windows.Forms.Label label;

private System.Windows.Forms.Button continueButton;

private System.Windows.Forms.Button reportButton;

Exception exceptionThrown;

public ExceptionBox(Exception e)

{

this.exceptionThrown = e;

InitializeComponent();

exceptionTextBox.Text = e.ToString();

ResourceManager resources = new ResourceManager("BitmapResources", Assembly.GetEntryAssembly());

}

string getClipboardString()

{

string str = "";

if (includeSysInfoCheckBox.Checked) {

str = ".NET Version : " + Environment.Version.ToString() + Environment.NewLine;

str += "OS Version : " + Environment.OSVersion.ToString() + Environment.NewLine;

str += "Boot Mode : " + SystemInformation.BootMode + Environment.NewLine;

str += "Working Set Memory : " + (Environment.WorkingSet / 1024) + "kb" + Environment.NewLine + Environment.NewLine;

Version v = Assembly.GetEntryAssembly().GetName().Version;

str += "SharpDevelop Version : " + v.Major + "." + v.Minor + "." + v.Revision + "." + v.Build + Environment.NewLine;

}

str += "Exception thrown: " + Environment.NewLine;

str += exceptionThrown.ToString();

return str;

}

void CopyInfoToClipboard()

{

if (copyErrorCheckBox.Checked) {

try {

Clipboard.SetDataObject(new DataObject(System.Windows.Forms.DataFormats.Text, getClipboardString()), true);

} catch (Exception) {}

}

// This method is used in the forms designer.

// Change this method on you own risk

void buttonClick(object sender, System.EventArgs e)

{

CopyInfoToClipboard();

// open IE via process.start to our bug reporting forum

Process.Start("http://yourreporturl/");

}

void continueButtonClick(object sender, System.EventArgs e)

{

// CopyInfoToClipboard();

DialogResult = System.Windows.Forms.DialogResult.Ignore;

}

void InitializeComponent()

}
