Run task in Visual Basic?
I am writing a small app in VB and I would like to know how I would set it up so that开发者_如何转开发 when a user pressed a button, a sechduled task is ran. Keep in mind that this task is already created, I just need it to run.
Any ideas?
Thanks
Use the System.Diagnostics.Process class. You can create a process and run it with Process.Start() method.
EDIT: Following code sample starts the helloworld.exe. This is just to give an idea about the Process class. You can find this example in Process.Start Method
using System;
using System.Diagnostics;
using System.ComponentModel;
namespace MyProcessSample
{
class MyProcess
{
public static void Main()
{
Process myProcess = new Process();
try
{
myProcess.StartInfo.UseShellExecute = false;
// You can start any process, HelloWorld is a do-nothing example.
myProcess.StartInfo.FileName = "C:\\HelloWorld.exe";
myProcess.StartInfo.CreateNoWindow = true;
myProcess.Start();
// This code assumes the process you are starting will terminate itself.
// Given that is is started without a window so you cannot terminate it
// on the desktop, it must terminate itself or you can do it programmatically
// from this application using the Kill method.
}
catch (Exception e)
{
Console.WriteLine(e.Message);
}
}
}
}
How about using the recently added System.Threading.Tasks library?
