The Magical magic of System.Diagnostics.Process.Start

Category:  C#+winform 2009-04-05 21:09 459 people Read reviews (0)   Favorites   Reports   We often encounter a link or button in WINFORM or WPF to open a specified URL, Or if you need to open a specific hard disk partition and folder in your computer, or even something related to the control Panel, how do you do it? The answer is to use System.Diagnostics.Process.Start (). Its role is to invoke external commands. Let's take a look at its invocation method: Process.Start ()   Process.Start (ProcessStartInfo)   Process.Start (String) Process.Start (string , string)   Process.Start (String, String, SecureString, String) Process.Start (String, String, String, SecureString, String) For example: C # Code:  System.Diagnostics.Process   ie   =   new   System.Diagnostics.Process ();      ie. startinfo.filename   =   "IEXPLORE. EXE ";      ie. startinfo.arguments   =   @ "http://www.baidu.com";   IE. Start ();    Concise call mode: System.Diagnostics.Process.Start ("http://www.baidu.com"); Of course, you can also use other browsers, such as proud tour instead of IE:             string mathonpath = @ "c:/program   Files/maxthon//maxthon.exe";             System.Diagnostics.Process p = new System.Diagnostics.Process ();            //Set Program name             p.startinfo.filename = Mathonpath;             p.startinfo.arguments = @ "c:/";             P.start (); If you want to open c:/with the Explorer, you can do this: System.Diagnostics.Process.Start ("Explorer.exe", @ "c:/"); More people might ask, "I'm going to open the Add or Remove Programs Panel or the control Panel, OK?" "The answer is YES!" How to do? The answer is to call rundll32.exe, for example: Open the "Add or Remove Programs" Panel: System.Diagnostics.Process.Start ("rundll32.exe", @ "Shell32.dll,control_ RunDLL appwiz.cpl,,1 "); The following "shell32.dll,Control_RunDLL appwiz.cpl,,1" is the parameter required to invoke the command. Here's a description, which is similar to the use in Delphi: ShellExecute (Handle, ' open ', ' rundll32.exe ', ' shell32.dll,control_rundll   Sysdm.cpl ', nil,sW_show);  winexec (' rundll32.exe   shell32.dll,control_rundll   sysdm.cpl ', SW_SHOW); About the purpose of rundll32.exe  --------------------------------------------------------------------------------command columns: rundll32.exe user.exe,restartwindows  function: System restart command column: rundll32.exe user.exe,exitwindows function: Shutdown system command column: Rundll32.exe shell32.dll,control_rundll  function: Display control Panel   Command column: rundll32.exe shell32.dll,control_rundll access.cpl,,1  function : Display control Panel-secondary Options-Keyboard Options window   Command column: rundll32.exe shell32.dll,control_rundll access.cpl,,2  function: Display "Control Panel-accessibility-sound" Options windows   Command columns: rundll32.exe shell32.dll,control_rundll access.cpl,,3  Features: Display the Control Panel-Accessibility-Display Options window   command columns: rundll32.exe shell32.dll,Control_RunDLL access.cpl,,4  Features: Display control Panel-secondary Options-Mouse Options window   Command column: rundll32.exe shell32.dll,Control_RunDLL access.cpl,,5  Features: Display control Panel-secondary Options-Legacy Options window   Command column: Rundll32.exe Shell32.dll,control_ RunDLL sysdm.cpl @1  Function: Executes the Control Panel-Add New Hardware wizard.   Command column: Rundll32.exe SHELL32.DLL,SHHELPSHORTCUTs_rundll addprinter  function: Execute the "Control Panel-Add new Printer" wizard.   Command column: rundll32.exe shell32.dll,control_rundll appwiz.cpl,,1  function: Displays the Control Panel-Add/Remove Programs-install/uninstall panel.   Command column: rundll32.exe shell32.dll,control_rundll appwiz.cpl,,2  function: Displays the Control Panel-Add/Remove Programs-install Windows panel.   Command column: rundll32.exe shell32.dll,control_rundll appwiz.cpl,,3  function: Displays the Control Panel-Add/Remove Programs-Startup disk panel.   Command column: Rundll32.exe syncui.dll,briefcase_create  feature: Create a new "My Briefcase" on the desktop.   Command column: rundll32.exe diskcopy.dll,diskcopyrundll  function: Display copy floppy window   command column: Rundll32.exe apwiz.cpl,newlinkhere %1  function: Displays the dialog box for "Create Shortcut", where the location of the shortcut is determined by the%1 parameter.   Command column: rundll32.exe shell32.dll,control_rundll timedate.cpl,,0  function: Displays the date and Time Options window.   Command column: rundll32.exe shell32.dll,control_rundll timedate.cpl,,1  function: Displays the Time Zone Options window.   Command column: rundll32.exe rnaui.dll,rnadial [Name of a dial-up connection]  feature: Displays the Dial-up window for a dial-up connection.

Process.Start (); This method is used to create a new process such as you want to add a hyperlink to the menu of a program to Baidu know then you can use this method to achieve System.Diagnostics.Process.Start ("iexplore.exe", "http/ Zhidao.baidu.com "); The first argument above can be omitted, but if you have an open page before, then you will jump from that page to   http://zhidao.baidu.com  open a new window, and of course you can use it to open a local program. For example, clicking on a button opens the Registry Editor, which should be System.Diagnostics.Process.Start (@ "C:\WINDOWS\REGEDIT.EXe "); System.Diagnostics.Process class application in. NET the client program that you develop needs to create a Word document from the image field of the database, and then call the Word program open, and the user edits and saves it back into the database. Where word is called to open the document with the System.Diagnostics.Process class, the relevant code is as follows:   String temppath = System.Environment.GetEnvironmentVariable ("TEMP"); String fileName = Path.Combine (TempPath, "01.doc");   Process wordprocess = new process (); WordProcess.StartInfo.FileName = FileName; WordProcess.StartInfo.Verb = "edit"; WordProcess.StartInfo.UseShellExecute = true; Wordprocess.start (); Wordprocess.waitforexit (); Wordprocess.close ();   MessageBox.Show ("Word exited!");   days ago has been good, but today in the implementation to   Wordprocess.waitforexit (); In this sentence, an unexpected message is "there is no process associated with this object." A closer look at the relevant documentation on MSDN is not explained in much detail, but this is included in the WaitForExit () method's documentation that mentions a possible exception. It suddenly occurred to me that it was possible that the word process had been opened, so it was not associated with the current process, so it would have happened. After you turn off the other word processes that are running, it is no longer a problem to do so. After some research, finally found that there is no word instance running in the case can achieve the requirements of the previous article method, the code is as follows:        string  TempPath = System.Environment.GetEnvironmentVariable ("TEMP");     string  fileName= Path.Combine (TempPath, "reasoning 01.doc");    string  Winwordpath = "";      //Determine if a Word instance is already running in the system.     process[] wordprocesses = Process.getprocessesbyname ("Winword");     foreach  (Process process in  wordprocesses)    {        Debug.WriteLine ( Process. MainWindowTitle);         Winwordpath = process. mainmodule.filename;       //If any, get the fully qualified name of the Winword.exe.        break;     }       Process wordprocess = new  Process ();       if  (winwordpath.length > 0)    //If there are instances of Word running, Use the/w parameter to force a new instance to be started and pass the file name as a parameter.  {         wordProcess.StartInfo.FileName = winwordpath;           Wordprocess.startinfo.UseShellExecute = false;         wordProcess.StartInfo.Arguments = fileName + "/w";      }    else                              //If there is no Word instance running, or {         wordProcess.StartInfo.FileName = filename;           WordProcess.StartInfo.UseShellExecute = true;     }        Wordprocess.start ();      wordprocess.waitforexit ();        //The current process is waiting until the Word instance exits.     Wordprocess.close ();
