我们单位购买了一个opc服务器开发工具包，安装后按照文档编写案例程序，总是不能执行，出现如下错误： Module File:i386\chkesp.c Line:42 The value of ESP was not properly saved across a function call.This is usually a result of calling a function declared with one calling convention with a function pointer declared with a different calling convention. 可是源代码没有任何的错误，不知道该如何解决这个问题，还请大家多多帮忙。
