Configuring Scanners Through the Mobile Devices SDK

101

Psion Mobile Devices Developers Guide

The following .NET code sample illustrates how to get and set scanner variables using the setting key/name

methods, and also illustrates how to create a list of all scanner setting index and key/name pairs.

// Create an instance of a ScannerServicesDriver object

PsionTeklogix.Barcode.ScannerServices.ScannerServicesDriver myScanner =

new PsionTeklogix.Barcode.ScannerServices.ScannerServicesDriver();

private void btnGetInfo_Click(object sender, EventArgs e)

{

// Get Click Data and Click Time values

// Note double backslashes due to escape sequence

tbClickData.Text = myScanner.GetProperty("Scs\\Click Data").ToString();

tbClickTime.Text = myScanner.GetProperty("Scs\\Click Time").ToString();

// Cycle through all scanner settings and list the index numbers

// and setting names in a combo box

for (int i = 0; i < myScanner.TotalSettingsCount; i++)

cbScanSetting.Items.Add(i.ToString() + ": "

+ myScanner.GetSettingName(i));

}

private void btnSetInfo_Click(object sender, EventArgs e)

{

// Set Click Data and Click Time values

myScanner.SetProperty("Scs\\Click Data", tbClickData.Text);

myScanner.SetProperty("Scs\\Click Time", int.Parse(tbClickTime.Text));

}
