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‘;

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;
}
}

public partial class Form1 : Form
{
public OpenFileDialog fdlg = new OpenFileDialog();//打开文件对话框
public string filename;
public Form1()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
ofdlg.Filter = "pdf文件(*.pdf)|*.pdf";//选择pdf文件
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;
case "XLS":
cr.ExportOptions.ExportFormatType=ExportFormatType.Excel;
dOpt.DiskFileName=strPath;
break;
default;
break;
}
cr.ExportOptions.DestinationOptions=dOpt;
cr.Export();
}
10 B/S下水晶报表的打印
priavte void PrintCRV(CrystalReport cr)
{
stringstrPrinterName=@"printName";
PageMargins margins=cr.PrintOptions.PageMargins;
margins.bottomMargin = 250;
margins.leftMargin = 350;
margins.rightMargin = 350;
margins.topMargin = 450;
cr.PrintOptions.ApplyPageMargins(margins);
cr.PrintOptions.printerName=strPrinterName;
cr.PrintToPrinter(1,false,0,0)//参数设置为0，表示打印所用页
}
96.全屏幕截取
[DllImport("gdi32.dll")]
private static extern int BitBlt(IntPtr hdcDest,int nXDest,int nYDest,int nWidth,int nHeight,IntPtr hdcSrc,int nXSrc,int nYSrc,UInt32 dwRop);
//this.Hide();//如果你不想截取的图象中有此应用程序
//Thread.Sleep(1000);
Rectangle rect = new Rectangle();
rect = Screen.GetWorkingArea(this);//获得当前屏幕的大小
Graphics g = this.CreateGraphics();
//创建一个以当前屏幕为模板的图象
Image myimage = new Bitmap(rect.Width, rect.Height, g);
//第二种得到全屏坐标的方法
// Image myimage = new Bitmap(Screen.PrimaryScreen.Bounds.Width,Screen.PrimaryScreen.Bounds.Height,g);
//创建以屏幕大小为标准的位图
Graphics gg = Graphics.FromImage(myimage);
IntPtr dc = g.GetHdc();//得到屏幕的DC
IntPtr dcdc = gg.GetHdc();//得到Bitmap的DC
BitBlt(dcdc, 0, 0, rect.Width, rect.Height, dc, 0, 0, 13369376);
//调用此API函数，实现屏幕捕获
g.ReleaseHdc(dc);//释放掉屏幕的DC
gg.ReleaseHdc(dcdc);//释放掉Bitmap的DC
myimage.Save(Application.StartupPath + @"\bob.jpg", ImageFormat.Jpeg);//以JPG文件格式来保存
this.Show();
97.区域截幕
public static Bitmap GetPartScreen(Point P1,Point P2,bool Full)
{
IntPtr hscrdc,hmemdc;
IntPtr hbitmap,holdbitmap;
int nx,ny,nx2,ny2;
nx=ny=nx2=ny2=0;
int nwidth, nheight;
int xscrn, yscrn;
hscrdc = CreateDC("DISPLAY", null, null, 0);//创建DC句柄
hmemdc = CreateCompatibleDC(hscrdc);//创建一个内存DC
xscrn = GetDeviceCaps(hscrdc, GetDeviceCapsIndex.HORZRES);//获取屏幕宽度
yscrn = GetDeviceCaps(hscrdc, GetDeviceCapsIndex.VERTRES);//获取屏幕高度
if(Full)//如果是截取整个屏幕
{
nx = 0;
ny = 0;
nx2 = xscrn;
ny2 = yscrn;
}
else
{
nx = P1.X;
ny = P1.Y;
nx2 =P2.X;
ny2 =P2.Y;
//检查数值合法性
if(nx<0)nx = 0;
if(ny<0)ny = 0;
if(nx2>xscrn)nx2 = xscrn;
if(ny2>yscrn)ny2 = yscrn;
}
nwidth = nx2 - nx;//截取范围的宽度
nheight = ny2 - ny;//截取范围的高度
hbitmap = CreateCompatibleBitmap(hscrdc, nwidth, nheight);//从内存DC复制到hbitmap句柄
holdbitmap = SelectObject(hmemdc, hbitmap);
BitBlt(hmemdc, 0, 0, nwidth, nheight,hscrdc, nx, ny,(UInt32)0xcc0020);
hbitmap = SelectObject(hmemdc, holdbitmap);
DeleteDC(hscrdc);//删除用过的对象
DeleteDC(hmemdc);//删除用过的对象
return Bitmap.FromHbitmap(hbitmap);//用Bitmap.FromHbitmap从hbitmap返回Bitmap
}
98.计算文件MD5值
string path = %%1;
FileStream fs = new FileStream(path,FileMode.Open,FileAccess.Read);
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
bool b=false;
string path = (%%2.LastIndexOf("\") == %%2.Length - 1) ? %%2 : %%2 + "\";
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
{
FileStream fs = new FileStream(f,FileMode.Open,FileAccess.Read);
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 %%3=sb.ToString();
}
