Let the process invoke the permission problem go to hell.

Recently you need to invoke a C + + component on the server side because the component will modify a target file, so in. NET uses the process object anyway to report a read-only error.

Search for data everywhere, most people say it involves invoking component modification files. NET is not allowed to do so. I almost blacked out. But I remember using the Wscript.Shell object when I used to write an ASP. So I started experimenting with ASP, without any errors, a rapture.

Then I found a useful message to convert Wscript.Shell to a DLL and call the method directly using. Net. Methods are as follows:

• Convert COM components to. NET components

Microsoft has provided us with the Type Library Importer (importer), through which we can use COM components. After the conversion, there will be a DLL file that needs to be placed in the bin directory of the Web directory in order for the component to be used.

Although this is more than one DLL, but this DLL does not need to register can be used directly, very convenient, which is asp.net and ASP, one of the differences. Haha, some BT administrators have nothing to remove the "harmful" components, now he has no way to ^_^

Wscript.Shell object is%windir%\system32\wshom.ocx, let's get it copy out, open the Visual Studio 2005 command prompt, use the type Library Importer conversion: Tlbimp.exe Wshom.ocx/ Out:WSHomx.dll

Then put the WSHomx.dll under the bin of the Web directory. Then write the code slightly different from the previous code.

The problem was finally solved and found to be more convenient than using ASP.

All the code is as follows:

Program code

public void Receive ()
{
String request = Requesthelper.requestgetvalue ("FileName");
WshShell CMD = new WshShell ();
String result = Cmd.exec (Voicetestpath + "" + Voiceoutputpath + request + ". WAV 2"). Stdout.readall ();
Httphelper.responsewrite (Result);
//The method of calling the process is invalid
//if (!string. IsNullOrEmpty (Request))
//{
//Httphelper.responsewrite (Executebyprocess (Voicetestpath, Voiceoutput Path + request + ". WAV 2");
//}
}

Else
p.WaitForExit (milliseconds);//This is waiting for the process End, wait time for the specified millisecond
output = P.standardoutput.readtoend ();//Read the output of the process
}
}

{
}
finally
{
if (P!= null)
P.close ();

return output;
}
