Visual Basicコードでコマンドプロンプトコマンドを実行する方法

Visual Basic、より具体的にはVisual Studio 2010で何かをコーディングしようとしています。ボタンをクリックするだけで、プログラムでコマンドを実行できます。それは可能ですか？

はい。 Process.Start コンソールアプリケーションを含む実行可能ファイルを起動します。

アプリケーションから出力を読み取る必要がある場合は、起動したアプリケーションから何かを出力するために、その StandardOutput ストリームから読み取る必要がある場合があります。

次に例を示します。

Process.Start("CMD", "/C Pause")


/C  Carries out the command specified by string and then terminates
/K  Carries out the command specified by string but remains

そしてここに拡張機能があります：（CMDコマンドを使用したコメント行に注意してください。）

または、本当に簡単な方法でそれを行うことができます。

Dim OpenCMD 
OpenCMD = CreateObject("wscript.Shell")
OpenCMD.run("Command Goes Here")

CreateProcessを使用する必要があります[ http://msdn.Microsoft.com/en-us/library/windows/desktop/ms682425（v = vs.85）.aspx ]

例：

LPTSTR szCmdline [] = _tcsdup（TEXT（ "\" C：\ Program Files\MyApp\"-L -S"））; CreateProcess（NULL、szCmdline、/.../）;
