推荐答案

在一个无符号整数字中.每个复选框应对应一个位.我希望您知道如何进行按位算术(二进制OR，AND，(``|''，``&'')，``<<''，``>>''等). ).

In one unsigned integer word. Each check box should correspond to one individual bit. I hope you know how to do bitwise arithmetic (binary OR, AND, (''|'', ''&''), ''<<'', ''>>'', etc.).

您正在将数据保存到列表中.

我想列表中的数据有点像这样，

You are saving the data into list.

And the data in list is somewhat like this i guess,

1 + 0 + 0 + 1 + and so on..

现在让我们考虑chkbox1 = 1，chkbox2 = 1，chkbox3 = 0，chkbox4 = 0，chkbox5 = 1，所以数据就像

Now let''s consider that chkbox1 = 1, chkbox2 = 1, chkbox3 = 0, chkbox4 = 0, chkbox5 = 1, so the data is like,

1 + 1 + 0 + 0 + 1

现在，您必须按如下所示拆分列表

Now here you have to split the list as shown below

String Data1 = ""
Data1 = Split(List1.List(i), "+")

这里的"+"是您的分隔符

现在检查Data1是否为1然后chkbox1.checked = true否则为false.

希望对您有帮助

Here ''+'' is your separator

Now check if Data1 is 1 Then chkbox1.checked = true else false.

Hope This will help you
