راهنما در مورد کدهای ناشناخته

[arashsoft]

سلام
کسی کاربرد کد های زیر را می داند؟

int max = 100;
var prog = Microsoft.WindowsAPICodePack.Taskbar.TaskbarManage r.Instance;
prog.SetProgressState(Microsoft.WindowsAPICodePack .Taskbar.TaskbarProgressBarState.Normal);
for(int i=0;i<max;i++) {
prog.SetProgressValue(i, max);
Thread.Sleep(100);
} prog.SetProgressState(Microsoft.WindowsAPICodePack .Taskbar.TaskbarProgressBarState.NoProgress);

دومی :

using System;
using System.Runtime.InteropServices;
public static class TaskbarProgress
{
public enum TaskbarStates
{
NoProgress = 0,
Indeterminate = 0x1,
Normal = 0x2,
Error = 0x4,
Paused = 0x8
}

TaskbarProgress.SetState(this.Handle, TaskbarProgress.TaskbarStates.Indeterminate);
or
TaskbarProgress.SetValue(this.Handle, 50, 100); TaskbarProgress.SetState(this.Handle,TaskbarProgre ss.TaskbarStates.Error);
