请高手们此招了，崩溃信息：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.




[解决办法]
ESP错误?
检查一下你的代码,调用方式是否正确.stdcall cdecll?

恭喜楼主自己解决问题！散个分吧。
