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

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();

}

}

}

Changing the User Agent in IE (.NET WebBrowser Control) Via C#

I’ve read a lot about this topic over the last couple hours, and all information I found seemed to be going about it the wrong way. Many people suggest changing the registry, but from what I tried it seemed to only allow you to change certain parts of the user agent, instead of the whole string. If you’re interested in this, you’ll want to change:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings\5.0\User Agent

Changing part of the User Agent wasn’t the goal though. The next idea I came across was that the WebBrowser.Navigate method took a headers string option that let you inject your own user agent into it. This would be useful if I was using the Navigate method instead of allowing users to click links and submit forms on pages. Luckily I ran into a COM method that lets you intercept all navigations, by form submits, link clicks, or anything else. Using this method, we can cancel the current navigation before it happens, edit the headers, and start the navigation again. I have extended the WebBrowser class so it allows simply setting of the UserAgent property to allow this.

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;

       xBrowser.BeforeNavigate2 += BeforeNavigate;

       DocumentCompleted += PageLoaded;

   }



   void PageLoaded(object sender, WebBrowserDocumentCompletedEventArgs e)

   {



   }



   void BeforeNavigate(object pDisp, ref object url, ref object flags, ref object targetFrameName,

       ref object postData, ref object headers, ref bool cancel)

   {

       if (!string.IsNullOrEmpty(UserAgent))

       {

           if (!renavigating)

           {

               headers += string.Format("User-Agent: {0}\r\n", UserAgent);

               renavigating = true;

               cancel = true;

               Navigate((string)url, (string)targetFrameName, (byte[])postData, (string)headers);

           }

           else

           {

               renavigating = false;

           }

       }

   }

}

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

I also stumbled across a PInvoke method that had a simpler solution. The following code shows how to change the user agent for the WebBrowser control to GoogleBot’s user agent.

[DllImport("urlmon.dll", CharSet = CharSet.Ansi)]

private static extern int UrlMkSetSessionOption(int dwOption, string pBuffer, int dwBufferLength, int dwReserved);



const int URLMON_OPTION_USERAGENT = 0x10000001;



public void ChangeUserAgent()

{

   string ua = "Googlebot/2.1 (+http://www.google.com/bot.html)";

   UrlMkSetSessionOption(URLMON_OPTION_USERAGENT, ua, ua.Length, 0);

}

After calling that method, you can just use your WebBrowser as normal. All pages it navigates to will use the user agent you specified. For more information, you can check out the documentation on UrlMkSetSessionOption . The only problem with this method is that the WebBrowser control seems to cache this user agent string, so it will not change the user agent without restarting the process.
