We are developing an application that will run on [url removed, login to view] 4.1. We need help on exactly how to create a simple eVB/VB.Net "hello world" app that will run on this device.
This device is a Winnia I640 which has a built in barcode scanner. We need to programmatically cause that barcode scanner to scan. There is already software on it by the manufacture that will allow us to cause the scanner to scan by pressing a physical button. The problem is that we do not know how to do this. Below is instructions from the manufacture.
On the registry setting, we have
"BUTTON1"="[url removed, login to view]"
"BUTTON2"="[url removed, login to view]"
"BUTTON3"="[url removed, login to view]"
"BUTTON4"="[url removed, login to view]"
"BUTTON5"="[url removed, login to view]"
If you want to write a program to trigger the barcode scanner directly, please write a COM1 "read" application. In this application, if you want to use a button, say BUTTON4 to trigger, please set the registry of "BUTTON4" to be "None". Then the keyboard driver will not activate the [url removed, login to view] application, but return the code you pressed VK_F3. So after you received VK_F3, you can use DTR_CONTROL_ENABLE to enable the DTR of COM1, then you triggered the barcode. After scanned, the barcode scanner will stop automatically, or you can use DTR_CONTROL_DISABLE to disable the barcode.
1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Installation package that will install the software (in ready-to-run condition) on the platform(s) specified in this bid request. 3) Complete ownership and distribution copyrights to all work purchased.
