The Magical magic of System.Diagnostics.Process.Start

We often encounter a link or button to open a specified URL in WinForm or WPF, or to open a designated hard disk partition and folder in your computer.
Even "control Panel" related things, then how to 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)
Like what:
C # Code:
System.Diagnostics.Process ie = new System.Diagnostics.Process ();
Ie. Startinfo.filename = "IEXPLORE. EXE ";
Ie. Startinfo.arguments = @ "http://www.baidu.com";
Ie. Start ();
Simple Invocation Method:
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:
To open the panel for Add or Remove Programs:
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 of 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);

net System.Diagnostics.Process.Start usage resolves a new instance of Word
Posted on 2011-06-02 15:15 codenote Read (645) Comments (0) Edit Collection
Original address

System.Diagnostics.Process.Start ();
This method is used to create a new process for example, you want to add a hyperlink to a program's menu to Baidu know so 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 this
If you have an open Web page then you will be redirected from that page to a new window with http://zhidao.baidu.com open.
Of course, you can also use it to open a local program, such as click a button to open the Registry Editor, it should be
System.Diagnostics.Process.Start (@ "C:\WINDOWS\regedit.exe"); problems encountered in System.Diagnostics.Process class applications 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 to the database
In 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!");

A few 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. Turn off the other word in the run
After the process, and then the implementation is sure that there is no problem.
After some research, finally found that there is no instance of Word 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, "Inference 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 is a Word instance 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 are no instances of Word running, or
{
WordProcess.StartInfo.FileName = FileName;
WordProcess.StartInfo.UseShellExecute = true;
}

Wordprocess.start ();
Wordprocess.waitforexit (); The current process waits until the Word instance exits.
Wordprocess.close ();
