我想使用函数来调整#include <iostream>
#include <pthread.h>
#include <sys/socket.h>
#include <sys/types.h>
#include <netinet/in.h>
#include <netdb.h>
#include <cstring>
#include <cstdlib>
#include <cstddef>

的{{1}}。这是简化的代码：
height但我收到错误：
运行时错误'424'：需要对象
在这一行：
ComboBox我该如何解决？感谢？
答案 0 :(得分：0)
您使用的括号不应该导致参数评估 - 它会传递Me.Data_Subject_Categories的值，而不是对象。
使用
Call Adjust_Box(Me.Data_Subject_Categories)
或
Adjust_Box Me.Data_Subject_Categories
