怎么用vb.net做心理测试 第一个窗口有一张图片 然后在选择A 就弹出一张图片 选择B 弹出
用2个单选控件
按钮下 如果 单选控件1状态是选中的 就显示窗体2 不是则显示窗体3
或者 你可以显示 图像框控件2
怎样在vb中自动检测到可用串口号的具体程序代码
vb.net的话
For
Each
sp
As
String
In
My.Computer.Ports.SerialPortNames
cbxport.Items.Add(sp)
Next
vb6.0的话要调用API查看串口相关信息存在的注册表。
HKEY_LOCAL_MACHINE\HARDWARE\DEVICEMAP\SERIALCOMM
通过读注册表的方法获得串口数量，当然也可以获得串口号了。

怎么用vb.net做一个简单的心理测试 就那种选择A出一张图 选择B弹出一张图
把图片存入资源，或把路径存放变量，在a,b的click事件中加载即可
