如果条件如何制作？

Question

我想知道是否可以创建一个If条件，以检查变量“ a”是否包含字符串“ pass”，然后显示错误消息？

dim a as string
a = textbox1.text
if a = "pass" then
label1.text = "Error: you can't use the word PASS in your password"
end if

Answer 1

dim a as string
a = textbox1.text
if InStr("fkvnfdpassknfd", "pass") > 0 then
label1.text = "Error: you can't use the word PASS in your password"
end if
