//using System.IO;
           FolderDialog aa = new FolderDialog();
            aa.DisplayDialog();
            if (aa.Path != "")
            {

                }
            }

70.获取磁盘所有分区后再把光驱盘符去除(用"\0"代替),把结果放在数组allfenqu[] 中,数组中每个元素代表一个分区盘符,不包括 :\\ 这样的路径,allfenqu[]数组开始时存放的是所有盘符。
当我用这样的代码测试结果是正确的,光驱盘符会被去掉:
//using System.IO;
stringroot; //root代表盘符路径
for(i=0;i<20;i++) //0-20代表最大的盘符数
{
root.Format("%c:\",allfenqu[i]);
if(GetDriveType(root)==5)
allfenqu[i]='\0';
}

但我用这样的代码时结果却无法去掉光驱盘符,allfenqu[]中还是会包含光驱盘符:
stringroot;
for(i=0;i<20;i++)
{
root=allfenqu[i]+":\";
if(GetDriveType(root)==5)
allfenqu[i]='\0';
}

71.激活一个程序或程序关联的文件
//using System.Diagnostics;
Process LandFileDivisison;
                    LandFileDivisison = new System.Diagnostics.Process();
                    LandFileDivisison.StartInfo.FileName = %%1;
                    LandFileDivisison.Start();

72.HTTP下载

        private void StartDownload()
        {
            //Start.Enabled = false;
            string URL = %%1;
            int n = URL.LastIndexOf("/");
            string URLAddress = URL.Substring(0, n);
            string fileName = URL.Substring(n + 1, URL.Length - n - 1);
            string Dir = %%2;
            string Path = Dir.ToString() + "\" + fileName;
            try
            {
                WebRequest myre = WebRequest.Create(URLAddress);
            }
            catch (WebException exp)
            {
                MessageBox.Show(exp.Message, "Error");
            }
            try
            {
                //statusBar.Text = "开始下载文件...";
                client.DownloadFile(URLAddress, fileName);
                Stream str = client.OpenRead(URLAddress);
                StreamReader reader = new StreamReader(str);
                byte[] mbyte = new byte[100000];
                int allmybyte = (int)mbyte.Length;
                int startmbyte = 0;
                //statusBar.Text = "正在接收数据...";
                while (allmybyte > 0)
                {
                    int m = str.Read(mbyte, startmbyte, allmybyte);
                    if (m == 0)
                        break;
                    startmbyte += m;
                    allmybyte -= m;
                }
                FileStream fstr = new FileStream(Path, FileMode.OpenOrCreate, FileAccess.Write);
                fstr.Write(mbyte, 0, startmbyte);
                str.Close();
                fstr.Close();
                //statusBar.Text = "下载完毕!";
                MessageBox.Show("下载完毕");
            }
            catch (WebException exp)
            {

82.把JButton或JTree组件写到一个流中

83.注册全局热键
注册全局热键要用到Windows的API方法RegisterHotKey和UnregisterHotKey。
一、声明注册热键方法 [DllImport("user32.dll")]
private static extern int RegisterHotKey(IntPtr hwnd, int id, int fsModifiers, int vk);
[DllImport("user32.dll")]
private static extern int UnregisterHotKey(IntPtr hwnd, int id);
int Space = 32; //热键ID
private const int WM_HOTKEY = 0x312; //窗口消息-热键
private const int WM_CREATE = 0x1; //窗口消息-创建
private const int WM_DESTROY = 0x2; //窗口消息-销毁
private const int MOD_ALT = 0x1; //ALT
private const int MOD_CONTROL = 0x2; //CTRL
private const int MOD_SHIFT = 0x4; //SHIFT
private const int VK_SPACE = 0x20; //SPACE
二、注册热键方法 /// <summary>
/// 注册热键
/// </summary>
/// <param name="hwnd">窗口句柄</param>
/// <param name="hotKey_id">热键ID</param>
/// <param name="fsModifiers">组合键</param>
/// <param name="vk">热键</param>
private void RegKey(IntPtr hwnd, int hotKey_id, int fsModifiers, int vk)
{
bool result;
if (RegisterHotKey(hwnd,hotKey_id,fsModifiers,vk) == 0)
{
result = false;
}
else
{
result = true;
}
if (!result)
{
MessageBox.Show("注册热键失败!");
}
}

/// <summary>
/// 注销热键
/// </summary>
/// <param name="hwnd">窗口句柄</param>
/// <param name="hotKey_id">热键ID</param>
private void UnRegKey(IntPtr hwnd, int hotKey_id)
{
UnregisterHotKey(hwnd,hotKey_id);
}
三、重写WndProc方法,实现注册 protected override void WndProc(ref Message m)
{
base.WndProc(ref m);
switch(m.Msg)
{
case WM_HOTKEY: //窗口消息-热键
switch(m.WParam.ToInt32())
{
case 32: //热键ID
MessageBox.Show("Hot Key : Ctrl + Alt + Shift + Space");
break;
   default:
   break;
}
break;
case WM_CREATE: //窗口消息-创建
RegKey(Handle,Space,MOD_ALT | MOD_CONTROL | MOD_SHIFT,VK_SPACE); //注册热键
break;
case WM_DESTROY: //窗口消息-销毁
UnRegKey(Handle,Space); //销毁热键
break;
default:
break;
}
}

            if (ofdlg.ShowDialog() == DialogResult.OK)
            {
                filename = string.Format("{0}", ofdlg.FileName);
            }          
        }
      //传送打开文件对话框中得到的filename来做为外部程序的参数来做转化
        private void button2_Click(object sender, EventArgs e)
        {
            Process p = new Process();
            string path = "pdftotext.exe"; //进程启用外部程序
                            //这个exe我放在debug文件夹下面      
            p.StartInfo.FileName = path;
            p.StartInfo.Arguments = string.Format( filename + " -");//很怪异的一行
                                  //参数“-”表示可以得到输出流
            p.StartInfo.UseShellExecute = false;
            p.StartInfo.RedirectStandardInput = true;
            p.StartInfo.RedirectStandardOutput = true;
            p.StartInfo.RedirectStandardError = true;
            p.StartInfo.CreateNoWindow = true;
          
            p.Start();
            string s = p.StandardOutput.ReadToEnd();//得到pdf文档中的文本内容
            textBox1.Text = s;
            p.Close();
        }
    }
}


上面的程序运行后,如果是在Debug文件夹下的pdf文件就可以得到输出,可是如果在打开文件对话框中打开我桌面上的一个pdf如:@"d:\我的文档\test.pdf",输出就会是空,但是如果把上面那怪异的一行改为:
C# code
p.StartInfo.Arguments = string.Format( @"d:\我的文档\test.pdf" + " -");


程序就又会得到输出。
呵呵,谢谢楼上的兄台,下载的xpdf中xpdftotext.exe用到的配置文件xpdfrc需要手动配置,我如果把那些字体啊,什么的映射成绝对路径下的文件,就不会出现上面的问题,但是我把配置文件中的路径改成了相对路径,于是就出现了上面的问题了,看兄台能够很轻易的就运行成功,一定是做过很多代码的,这里还得劳烦兄台再给看一下,帮下忙,能遇到一个大神不容易,大神可不能吝啬啊,先谢过了哈

95.报表相关

2、水晶报表的两种格式
   1)pull模式,不利用DataSet,直接从数据库中取出数据
   2) push模式,使用DataSet,利用它进行数据的加载和处理等
3. 水晶报表使用的库
   1)水晶报表的引擎(CREnging.dll),作用:合并数据,装换格式
   2)水晶报表设计器(CRDesigner.dll),作用:设计标题,插入数据等
   3)水晶报表查看控件(CRWebFormViewer.DLL)
   4)需要引入的命名空间
     using CrystalDecisions.CrystalReports.Engine;
     using CrystalDecisions.Shared;
4、Pull模式下使用水晶报表
   1)创建rpt文件
   2)拖放CrystalReportViewer
   3)绑定
5、读取水晶报表文件
   private void ReadCRV(cryatalReportViewer crv)
   {
     openFileDialog dlg=new OpenFileDialog();
     dlg.Title="打开水晶报表文件";
     dlg.Filter="水晶报表文件(*.rpt)|*.rpt|所有文件|*.*";
     if(dlg.showDialog()==DialogResult.OK)
     {
       crv.ReportSource=dlg.FileName;
     }
   }
6. B/S下读取报表的文件
    private void ReadCRV(cryatalReportViewer crv,File file)
    {
      string strName=file.PostedFile.FileName;
      if(strName.Trim()!="")
      {
        crv.ReportSource=strName
        Session["fileName"]=strName;
      }
    }
    在B/S中要防止数据源的丢失
    priavte void Page_Load(object sender,System.EventArgs e)
    {
      if(Session["fileName"]!=null)
      {
        crv.ReportSource=Session["fileName"].ToString();
      }
    }
7. 假如直接从数据库中读取数据,采用PULL模式可能出现错误(登录的用户名和密码不对)
   private void ReadCRV(CrystalReportViewer crv,CrystalReport cr)
   {
      ReportDocument reportDoc=new ReportDocument();
      reportDoc.Load(Server.MapPath(cr));//要加载的rpt文件的名字
      //解决登录的问题
      TableLogOnInfo logonInfo = new TableLogOnInfo();
      foreach(Table tb in ReportDoc.Database.Tables)
      {
        logonInfo=tb.LogOnInfo;
        logonInfo.ConnectionInfo.ServerName="(loacl)";
        logonInfo.ConnectionInfo.DatabaseName="Pubs";
        logonInfo.ConnectionInfo.UserId="sa";
        logonInfo.ConnectionInfo.Password="";
        tb.ApplyLogOnInfo(logonInfo);
      }
      crv.ReportSource=reportDoc;
   }
8. 采用Push模式,直接在数据源读取
   private void BindReport(CrystalReportViewer crv)
   {
     string strProvider="Server=(local);DataBase=pubs;uid=sa;pwd=";
     CrystalReport cr=new CrystalReport();
     DataSet ds=new DataSet();
     SqlConnection conn=new SqlConnection(strProvider);
     conn.open();
     string strSql="select * from jobs";
     SqlDataAdapter dap=new SqlDataAdapter(strSql,conn);
     adp.Fill(ds,"jobs");
     cr.SetDataSource(ds);
     crv.ReportSource=cr;
   }
9. 导出水晶报表的文件
   private void ExportCrv(CrystalReport cr)
   {
      DiskFileDestionOptions dOpt=new DiskFileDestionOptions();
      cr.ExportOptions.ExportDestinationType=ExportDestinationType.DiskFile();
      cr.ExportOptions.ExportFormatType= ExportFormatType.PortableDocFormat;
      dOpt.DiskFileName="C:\output.pdf";
      cr.ExportOptions.DestinationOptions=dOpt;
      cr.Export();
    
   }
   private void ExportCrv(CrystalReport cr,string strType,string strPath)
   {
      DiskFileDestionOptions dOpt=new DiskFileDestionOptions();
      cr.ExportOptions.ExportDestinationType=ExportDestinationType.DiskFile();
      switch(strType)
      {
         case "RTF":
           cr.ExportOptions.ExportFormatType=ExportFormatType.RichText;
           dOpt.DiskFileName=strPath;
           break;
         case "PDF":
           cr.ExportOptions.ExportFormatType=ExportFormatType.PortableDocFormat;
           dOpt.DiskFileName=strPath;
           break;
         case "DOC":
           cr.ExportOptions.ExportFormatType=ExportFormatType.WordForWindows;
           dOpt.DiskFileName=strPath;
           break;

MD5CryptoServiceProvider md5 = new MD5CryptoServiceProvider();
byte [] md5byte = md5.ComputeHash(fs);
int i,j;
StringBuilder sb = new StringBuilder(16);
foreach (byte b in md5byte)
{
    i = Convert.ToInt32(b);
   j = i >> 4;
   sb.Append(Convert.ToString(j,16));
   j = ((i << 4) & 0x00ff) >> 4;
   sb.Append(Convert.ToString(j,16));
}
string %%2=sb.ToString();

99.计算获取文件夹中文件的MD5值

string parent = Path.GetDirectoryName(%%1);
Directory.CreateDirectory(path + Path.GetFileName(%%1));
DirectoryInfo dir = new DirectoryInfo((%%1.LastIndexOf("\") == %%1.Length - 1) ? %%1 : %%1 + "\");
FileSystemInfo[] fileArr = dir.GetFileSystemInfos();
Queue<FileSystemInfo> Folders = new Queue<FileSystemInfo>(dir.GetFileSystemInfos());
while (Folders.Count > 0)
{
    FileSystemInfo tmp = Folders.Dequeue();
    FileInfo f = tmp as FileInfo;
    if (b && f == null)
    {
        DirectoryInfo d = tmp as DirectoryInfo;
        Directory.CreateDirectory(d.FullName.Replace((parent.LastIndexOf("\") == parent.Length - 1) ? parent : parent + "\", path));
        foreach (FileSystemInfo fi in d.GetFileSystemInfos())
        {
            Folders.Enqueue(fi);
        }
    }
    else
