[Microsoft Visual Basic 2013 Express]執行Cmd指令

開發環境：Microsoft Visual Basic 2013 Express

原理　　：用Cmd來做到從外部執行指令並取得傳回值

Public Function Cmd(ByVal Command As String) As String
      Dim process As New System.Diagnostics.Process()
      process.StartInfo.FileName = "cmd.exe"
      process.StartInfo.UseShellExecute = False
      process.StartInfo.RedirectStandardInput = True
      process.StartInfo.RedirectStandardOutput = True
      process.StartInfo.RedirectStandardError = True
      process.StartInfo.CreateNoWindow = True
      process.Start()
      process.StandardInput.WriteLine(Command)
      process.StandardInput.WriteLine("exit")
      Dim Result As String = process.StandardOutput.ReadToEnd()
      process.Close()
      Return Result
End Function

現在，我要用程式找IP:

Dim result As String

result = Cmd(“ipconfig")

Debug.Print(result)

這樣會印出所有Cmd上面的內容。

[Microsoft Visual Basic 2010 Express]背景音樂

開發環境：Microsoft Visual Basic 2010 Express

原理　　：利用Windows Media Player的dll檔（wmp.dll），讓在VB2010可以使Windows

                    Media Player的功能。

Imports WMPLib

Public Class Form1

    Public wmp As New WindowsMediaPlayer

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

        wmp.URL = System.Windows.Forms.Application.StartupPath & "\Angel Beats!PV6使用曲 ロック風アレンジ Reloaded.mp3"

    End Sub

    Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click

        wmp.close()

    End Sub

End Class

windows media player 控件的常用屬性及方法

屬性/方法 說明
URL:String; 指定媒體位置，本機或網絡地址
uiMode:String; 播放器界面模式，可為Full, Mini, None, Invisible
playState:integer; 播放狀態，1=停止，2=暫停，3=播放，6=正在緩衝，9=正在連接，10= 準備就緒
enableContextMenu:Boolean; 啟用/禁用右鍵菜單
fullScreen:boolean; 是否全屏顯示
[Ctlcontrols] wmp.controls 播放器基本控製
Ctlcontrols.play; 播放
Ctlcontrols.pause; 暫停
Ctlcontrols.stop; 停止
Ctlcontrols.currentPosition:double; 當前進度
Ctlcontrols.currentPositionString:string; 當前進度，字符串格式。如“00:23”
Ctlcontrols.fastForward; 快進
Ctlcontrols.fastReverse; 快退
Ctlcontrols.next; 下一曲
Ctlcontrols.previous; 上一曲
[settings] wmp.settings 播放器基本設置
settings.volume:integer; 音量，0-100
settings.autoStart:Boolean; 是否自動播放
settings.mute:Boolean; 是否靜音
settings.playCount:integer; 播放次數
[currentMedia] wmp.currentMedia 當前媒體屬性
currentMedia.duration:double; 媒體總長度
currentMedia.durationString:string; 媒體總長度，字符串格式。如“03:24”
currentMedia.getItemInfo(const string);取當前媒體信息"Title"=媒體標題，"Author"=藝術家，"Copyright"=版權信息，"Description"= 媒體內容描述，"Duration"=持續時間（秒），"FileSize"=文件大小，"FileType"=文件類型，"sourceURL"=原始 地址
currentMedia.setItemInfo(const string); 通過屬性名設置媒體信息
currentMedia.name:string; 同 currentMedia.getItemInfo("Title")
[currentPlaylist] wmp.currentPlaylist //當前播放列表屬性
currentPlaylist.count:integer; 當前播放列表所包含媒體數
currentPlaylist.Item[integer]; 獲取或設置指定項目媒體信息，其子屬性同wmp.currentMedia再使用currentMedia.duration

特別要注意 Player 需要Ctlcontrols.play()

才能取值

特別注意的是player可能檔案載入或是串流載入

可能未準備好而造成取得的值是0

我的解決方式是透過timer在一定時間(interval=3000)後再取值
