RussianВопрос
Мне действительно нужна помощь в реализации Motorola MC9090-G в наше программное приложение. Это мой первый раз, чтобы работать над этим проектом, поэтому я не знаю, с чего начать. Любая помощь действительно будет оценена.
Я уже загрузил EMDK для сканера штрих-кода (.NET V2.4). То, что я пытаюсь сделать сейчас, это просто подключить MC9090-G к моему простую тестовое приложение, которое в нем есть текстовое поле. Сканируйте штрих-код, отобразите отсканированного штрих-кода в текстовом поле и именно! Я просто спрашиваю, это кто-то может дать мне шаг за шагом процесс о том, как я мог это сделать? Большая часть помощи, которую я получаю из Интернета, развернут приложение в сканере, который я не хочу делать сейчас. Я верю, что это будет отличным шагом для меня! Так что спасибо заранее! :))
Решение
Вы смотрели на пример приложения Motorola? Я нашел выборки приложений, включенных в EMDK, очень поучительно при изучении этого сам. У них есть несколько основных образцов, которые позволяют довольно очевидны несколько строк кода, которые необходимы для доступа к оборудованию сканера штрих-кода.
Другие советы
Добро пожаловать в самый расстраивающий сканер, с которым я когда-либо играл.
(Дайте мне тупой сканер, который действует как клавиатура HID в любой день!)
Я написал небольшое приложение, которое включает в себя текстовое поле, список списков и кнопку или два.
В основном, клин сканера разместит отсканированные данные в то, что когда-либо сосредоточено.
Одна из проблем, которые я имел знать, когда данные сканера были оснащены данными. Итак, я добавил таймер.
Следующая проблема, и тот, который я нашел нет простое решение, чтобы выдвинуть данные с сканера и в настоящий Компьютер, ли Linux на основе Windows.
Центр мобильного устройства Windows и активная синхронизация требует слишком большого количества взаимодействия оператора.
Лучше всего я придумал, это открыть окно Hyper Terminal. Но это все клюд.
Итак, куда мне не повезло, используя синий зуб. Мой код формы ниже. Надеюсь, поможет. Это модификация одной из их образцов. Я использую EMDK 2.8
