使用串行通信控制轨迹栏 [英] Control trackbar using serial communication

问题描述

我创建了一个应用程序，我需要在VB.Net中使用水平轨迹栏控制来控制数模转换器（DAC）。

我使用了复选框（外观：按钮）来控制继电器打开和关闭它们，我从程序发送Ascii值来做它。

轨道栏是否可以做同样的事情？我很困惑，因为不像复选框控件可以给出两个离散值我需要连续值的轨迹栏。

我是VB.Net的新手所以任何帮助将不胜感激。



我尝试了什么：



我尝试将ascii值发送到轨道栏控件但是它不起作用。

I have created an application where I need to control a Digital to Analogue Converter (DAC) using horizontal trackbar control in VB.Net.
I have used checkbox (appearance: button) to control relays to switch them on and off and I'm sending Ascii values from program to do it.
Is it possible to do the same for trackbar? I am confused because unlike checkbox control which can be given two discrete values I'll need continuous values for trackbar.
I am new to VB.Net so any help will be appreciated.

What I have tried:

I have tried sending ascii values to the trackbar control but it doesn't work.

推荐答案

你是什么意思'将ascii值发送到轨迹栏控件'...？您可以设置跟踪栏的值，最小值和最大值 - 这可能有助于 Windows Control：跟踪栏 [ ^ ]通知您通常使用轨迹栏设置/获取范围[min，max]

How do you mean 'send ascii values to the trackbar control' ... ? you can set the Value, Minimum and Maximum for a trackbar - this may help Windows Control: The Track Bar[^] notice you're usually using a trackbar to set/get an 'integer' value between a range [min, max]
