FileVersionInfo^ myFileVersionInfo =
FileVersionInfo::GetVersionInfo( Environment::SystemDirectory + "\\Notepad.exe" );

textBox1->Text = String::Concat( "File has patch installed: ", myFileVersionInfo->IsPatched );
}
C#
private void GetIsPatched()
{
// Get the file version for the notepad.
FileVersionInfo myFileVersionInfo =
FileVersionInfo.GetVersionInfo(Environment.SystemDirectory + "\\Notepad.exe");
// Print whether the file has a patch installed.
textBox1.Text = "File has patch installed: " + myFileVersionInfo.IsPatched;
}
Private Sub GetIsPatched()
' Get the file version for the notepad.
Dim myFileVersionInfo As FileVersionInfo = _
FileVersionInfo.GetVersionInfo(Environment.SystemDirectory + "\Notepad.exe")
' Print whether the file has a patch installed.
textBox1.Text = "File has patch installed: " & myFileVersionInfo.IsPatched
End Sub
