Problems encountered in system. Diagnostics. process applications in. Net (continued)

After some research, I finally found out whether the previous article can be implemented even if the word instance is running. Article The required method in, Code 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 In Wordprocesses)
{< br> 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 ();
