4 The iX example project
The cyclic check for USB and SD media is done inside the script module SCM_USB_SD_Check.
The Script Module
{
}
Inside the script module the following Namespace is inserted additionally to enable access to the file system. using System.IO;
Every iX script module brings a “Created” method with it, which is perfect to initialize stuff as it is worked on exactly once at the start of the iX project.
// The method is invoked when the script module object is created. void SCM_USB_SD_Check_Created(System.Object sender, System.EventArgs e)
{ m_Timer= new Timer(); m_Timer.Enabled = true; m_Timer.Interval = 1000; m_Timer.Tick += OnTimerTick;
//ms - adjust time for cyclic check here.
}
// Cycle private void OnTimerTick(System.Object sender, System.EventArgs e) if(Directory.Exists("\\Hard Disk")) else
Globals.Tags.USB_plugged_In.SetTag();
// Check if USB key is connected
// Set tag if connected
// Reset tag if disconnected Globals.Tags.USB_plugged_In.ResetTag(); if(Directory.Exists("\\Storage Card"))
Globals.Tags.SD_plugged_In.SetTag(); else
Globals.Tags.SD_plugged_In.ResetTag(); // Reset tag if disconnected
// Check if USB key is connected
// Set tag if connected
