Example

This method can be used in stand-alone mode, but it make more sense to use it with some other kind of Datalogic.API’s features: in the example below we will show how to use the SoftTrigger method together with Events, Buttons, going through the DecodeRequest type.

public partial class Form1 : Form

{

private DecodeEvent dcdEvent;

private DecodeHandle hDcd;

public Form1()

{

InitializeComponent();

InitDecodeEngine();

}

public void InitDecodeEngine()

{

// Make a new decoder handler.

hDcd = new DecodeHandle(DecodeDeviceCap.Exists | DecodeDeviceCap.Barcode);

// Make a new decoder request in PostRecurring mode

DecodeRequest reqType = (DecodeRequest)1 | DecodeRequest.PostRecurring;

// Make the new Event Object.

dcdEvent = new DecodeEvent(hDcd, reqType, this);

// adding the scanning event to the event queue.

dcdEvent.Scanned += new DecodeScanned(dcdEvent_Scanned);

// adding the timeout event to the event queue.

dcdEvent.TimeOut += new DecodeTimeOut(dcdEvent_Timeout);

}

private void bScan_Click(object sender, EventArgs e)

{

// Start Scanning.

hDcd.SoftTrigger(DecodeInputType.Barcode, 5000);

}
