问题描述

MFC中pDl->OnSend(nErrorCode)

使用此语句：pDl->OnSend(nErrorCode)，出现如下错误：
Run-Time Check Failure #0 - 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.
请问是什么原因，该怎么解决？

解决方案

你的强制类型转换的目标类型和原始类型不匹配。检查你的代码。
