编译错误 byref 参数类型不匹配

Question

我在传递ByRef 变量方面已经有经验了。我知道我必须在调用过程和被调用过程中声明它们（当然是同一类型）。我这样做了，但仍然出现编译错误。

这是失败的调用：

transition = reply_manager(CommentfirstJSON, a_b_c_d) 

标记了变量a_b_c_d。它是一个字符串，被调用的函数需要一个字符串。那我做错了什么？

Answer 1

问题是你认为你已经将它声明为String

Dim a_b_c_d, abcd As String

与 VB.Net 不同，它们都将被声明为 String，在 VBA 中只有第二个，即 abcd 将被声明为 String。第一个，即a_b_c_d 将被声明为Variant

你必须明确声明两者。

Dim a_b_c_d As String, abcd As String
