Changing the UserAgent of the WebBrowser control -Winforms C#

http://stackoverflow.com/questions/937573/changing-the-useragent-of-the-webbrowser-control-winforms-c

public class ExtendedWebBrowser : WebBrowser
{
bool renavigating = false;

public string UserAgent { get; set; }

public ExtendedWebBrowser()
{
DocumentCompleted += SetupBrowser;

//this will cause SetupBrowser to run (we need a document object)
Navigate("about:blank");
}

void SetupBrowser(object sender, WebBrowserDocumentCompletedEventArgs e)
{
DocumentCompleted -= SetupBrowser;
SHDocVw.WebBrowser xBrowser = (SHDocVw.WebBrowser)ActiveXInstance;

}

void BeforeNavigate(object pDisp, ref object url, ref object flags, ref object targetFrameName,
ref object postData, ref object headers, ref bool cancel)

if (!renavigating)

Note: To use the method above you’ll need to add a COM reference to “Microsoft Internet Controls”.

C#调用其他的应用程序

System.Diagnostics.Process.Start("notepad.exe","c:\\readme.txt");

//最小化方式启动
Info.WindowStyle = System.Diagnostics.ProcessWindowStyle.Minimized;

c# 窗体最小化到托盘

转：http://www.cnblogs.com/qfb620/archive/2009/10/22/1587971.html

c# winform最小化到托盘,也就是最小化到右下角，其实很简单，winform中有专门的控件。

下面是完整的代码，没太多需要解释的。

先在winform中添加notifyIcon控件，然后激活相应事件，添加代码。因为屏蔽了关闭窗体事件,可以设定一个全局变量bool变量来分辨是哪里引起的close事件。

注意添加Form的SizeChanged事件和NotifyIcon控件的DoubleClick事件

//全家变量bool closeTag = true;
//最小化
private void form1_Resize(object sender, EventArgs e)
{
if (this.WindowState == FormWindowState.Minimized)
{
NormalToMinimized();
}
}
//close时最小化
private void form1_FormClosing(object sender, FormClosingEventArgs e)
{
e.Cancel = true;
NormalToMinimized();
}
//单击显示窗体
private void notifyIcon_MouseClick(object sender, MouseEventArgs e)
{
if (e.Button == MouseButtons.Left)
{
this.MinimizedToNormal();
}
}
private void MinimizedToNormal()
{
this.Visible = true;
this.WindowState = FormWindowState.Normal;
notifyIcon.Visible = false;
}
private void NormalToMinimized()
{
this.WindowState = FormWindowState.Minimized;
this.Visible = false;
this.notifyIcon.Visible = true;
}
private void frmMain_FormClosing(object sender, FormClosingEventHandler e)
{
if (closeTag)
{
e.Cancel = true;
NormalToMinimized();
}
}
//托盘右键关闭事件
private void 退出XToolStripMenuItem_Click(object sender, EventArgs e)
{
closeTag = false;
Application.Exit();
}

怎样保证一个窗体始终是处在最顶层的

[C#]
public bool TopMost {get; set;}

属性值
如果为 true，则将窗体显示为最顶层窗体；否则，为 false。默认为 false。

TopMost只是设置窗口为本程序的最顶层窗口。

而不是系统的，要设置系统的，可以用API：setwindowspos：

[DllImport("user32.dll")]
private static extern int SetWindowPos (int hwnd, int hWndInsertAfter, int x, int y, int cx, int cy, int wFlags);
//int x:窗口新的x坐标。如hwnd是一个子窗口，则x用父窗口的客户区坐标表示
//int y:窗口新的y坐标。如hwnd是一个子窗口，则y用父窗口的客户区坐标表示
//int cx:指定新的窗口宽度
//int cy:指定新的窗口高度
private const int HWND_TOPMOST = -1;
private const int SWP_SHOWWINDOW = 0x40;

SetWindowPos(this.Handle, HWND_TOPMOST, 0, 0, 500, 500, 0x40);

Form in corner of screen

Location = new Point(Screen.PrimaryScreen.WorkingArea.Right - Width,
Screen.PrimaryScreen.WorkingArea.Bottom - Height);

C#连接MySQL数据库方法

转:http://kinghongchen.blog.163.com/blog/static/71647228200871114425689/

1、用MySQLDriverCS连接MySQL数据库

先下载和安装MySQLDriverCS，地址：

http://sourceforge.net/projects/mysqldrivercs

在安装文件夹下面找到MySQLDriver.dll，然后将MySQLDriver.dll添加引用到项目中

注：我下载的是版本是 MySQLDriverCS-n-EasyQueryTools-4.0.1-DotNet2.0.exe

using System;

using System.Collections.Generic;

using System.ComponentModel;

using System.Data;

using System.Data.Odbc;

using System.Drawing;

using System.Linq;

using System.Text;

using System.Windows.Forms;

using MySQLDriverCS;



namespace mysql

{

public partial class Form1 : Form

{

public Form1()

{

InitializeComponent();

}



private void Form1_Load(object sender, EventArgs e)

{



MySQLConnection conn = null;

conn = new MySQLConnection(new MySQLConnectionString("localhost", "inv", "root", "831025").AsString);

conn.Open();



MySQLCommand commn = new MySQLCommand("set names gb2312", conn);

commn.ExecuteNonQuery();



string sql = "select * from exchange ";

MySQLDataAdapter mda = new MySQLDataAdapter(sql, conn);



DataSet ds = new DataSet();

mda.Fill(ds, "table1");



this.dataGrid1.DataSource = ds.Tables["table1"];

conn.Close();



}

}

}

2、通过ODBC访问mysql数据库：

参考：http://www.microsoft.com/china/community/Column/63.mspx



1. 安装Microsoft ODBC.net：我安装的是mysql-connector-odbc-3.51.22-win32.msi

2. 安装MDAC 2.7或者更高版本：我安装的是mdac_typ.exe 2.7简体中文版

3. 安装MySQL的ODBC驱动程序：我安装的是 odbc_net.msi

4. 管理工具 -> 数据源ODBC –>配置DSN…

5. 解决方案管理中添加引用 Microsoft.Data.Odbc.dll(1.0.3300)

6. 代码中增加引用 using Microsoft.Data.Odbc;



using System;

using System.Collections.Generic;

using System.ComponentModel;

using System.Drawing;

using System.Linq; //vs2005好像没有这个命名空间，在c#2008下测试自动生成的

using System.Text;

using System.Windows.Forms;

using Microsoft.Data.Odbc;



namespace mysql

{

public partial class Form1 : Form

{

public Form1()

{

InitializeComponent();

}



private void Form1_Load(object sender, EventArgs e)

{



string MyConString = "DRIVER={MySQL ODBC 3.51 Driver};" +

"SERVER=localhost;" +

"DATABASE=inv;" +

"UID=root;" +

"PASSWORD=831025;" +

"OPTION=3";

OdbcConnection MyConnection = new OdbcConnection(MyConString);

MyConnection.Open();

Console.WriteLine("\n success, connected successfully !\n");



string query = "insert into test values( 'hello', 'lucas', 'liu')";

OdbcCommand cmd = new OdbcCommand(query, MyConnection);



//处理异常：插入重复记录有异常

try{

cmd.ExecuteNonQuery();

}

catch(Exception ex){

Console.WriteLine("record duplicate.");

}finally{

cmd.Dispose();

}



//***********************用read方法读数据到textbox**********************

string tmp1 = null;

string tmp2 = null;

string tmp3 = null;

query = "select * from test ";

OdbcCommand cmd2 = new OdbcCommand(query, MyConnection);

OdbcDataReader reader = cmd2.ExecuteReader();

while (reader.Read())

{

tmp1 = reader[0].ToString();

tmp2 = reader[1].ToString();

tmp3 = reader[2].ToString();

}

this.textBox1.Text = tmp1 + " " + tmp2 + " " + tmp3;

*/



//************************用datagridview控件显示数据表**************************

string MyConString = "DRIVER={MySQL ODBC 3.51 Driver};" +

"SERVER=localhost;" +

"DATABASE=inv;" +

"UID=root;" +

"PASSWORD=831025;" +

"OPTION=3";

OdbcConnection MyConnection = new OdbcConnection(MyConString);

OdbcDataAdapter oda = new OdbcDataAdapter("select * from customer ", MyConnection);

DataSet ds = new DataSet();

oda.Fill(ds, "employee");

this.dataGridView1.DataSource = ds.Tables["employee"];

*/



MyConnection.Close();

}

}

}
