System. Diagnostics. Process. Start, systemdiagnostics

We often encounter a problem of clicking a link or button in Winform or WPF to open a specified website or opening a specified hard disk partition and folder on the computer,
How can we do something even related to "Control Panel?
The answer is to use System. Diagnostics. Process. Start (). It is used to call external commands.
Let's take a look at its call method:
Process. Start ()
Process. Start (ProcessStartInfo)
Process. Start (String)
Process. Start (String, String)
Process. Start (String, String, SecureString, String)
Process. Start (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 ();
Simple call method:
System. Diagnostics. Process. Start ("http://www.baidu.com ");
Of course, you can also use other browsers, such as aoyou rather than IE:
String mathonPath = @ "C:/Program Files/Maxthon // Maxthon.exe ";
System. Diagnostics. Process p = new System. Diagnostics. Process (); // set the program name
P. StartInfo. FileName = mathonPath;
P. StartInfo. Arguments = @ "c :/";
P. Start ();
If you want to use the resource manager to open C:/, you can do this:
System. Diagnostics. Process. Start ("assumer.exe", @ "c :/");
Someone may ask, "Can I open the" add or delete programs "Panel or control panel related content ?" The answer is yes!
How to do it? The answer is to call rundll32.exe, for example:
Open the "add or delete programs" panel:
System. Diagnostics. Process. Start ("rundll32.exe", @ "shell32.dll, Control_RunDLL appwiz. cpl, 1 ");
The following "shell32.dll, Control_RunDLL appwiz. cpl, and 1" are the parameters required to call the command.
This is similar to using 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 );

In net, the usage of System. Diagnostics. Process. Start solves the problem of a new word instance.

System. Diagnostics. Process. Start ();
This method is used to create a new process. For example, if you want to add a hyperlink to the menu of a program to Baidu, you can use this method.
System. Diagnostics. Process. Start ("iexplore.exe", "http://zhidao.baidu.com"); the first parameter can be omitted, but if
You have opened the web page will jump from that web page to the http://zhidao.baidu.com did not open, then open a new window
Of course, you can also use it to open a local program. For example, if you 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 applications in. NET
A self-developed client program needs to create a Word document from the Image field of the database, then call the Word program to open it, the user edits and saves it, And then stores it in the database.
. The System. Diagnostics. Process class is used to call the Word to open the document. 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! ");
 
It has been easy to use for a few days, but an error occurred while executing wordProcess. WaitForExit () today. The message is "no process associated with this object ".
The relevant documentation in MSDN is not explained in detail, but it is included in the documents of the WaitForExit () method.
Suddenly, is it possible that the Word process has been opened, so it is not associated with the current process, so this accident occurs. Turn off other running Word
After the process, the execution is OK.
After some research, I finally found the method that can meet the requirements in the previous article when there is no Word instance running. The Code is as follows:
 
 
String tempPath = System. Environment. GetEnvironmentVariable ("TEMP ");
String fileName = Path. Combine (tempPath, "reasoning 01.doc ");
String winwordPath = "";

// Determine whether a Word instance is running in the system.
Process [] wordProcesses = Process. GetProcessesByName ("winword ");
Foreach (Process process in wordProcesses)
{
Debug. WriteLine (process. MainWindowTitle );
WinwordPath = process. MainModule. FileName; // obtain the fully qualified name of Winword.exe if any.
Break;
}

Process wordProcess = new Process ();

If (winwordPath. Length> 0) // if a Word instance is running, use the/w parameter to forcibly start the new instance and pass the file name as a parameter.
{WordProcess. StartInfo. FileName = winwordPath;
WordProcess. StartInfo. UseShellExecute = false;
WordProcess. StartInfo. Arguments = fileName + "/w ";
}
Else // if no Word instance is running
{
WordProcess. StartInfo. FileName = fileName;
WordProcess. StartInfo. UseShellExecute = true;
}

WordProcess. Start ();
WordProcess. WaitForExit (); // the current process is waiting until the Word instance exits.
WordProcess. Close ();
