错误:处置方法和链接错误:LNK2020 LNK2019 [英] Error: in Dispose Method and Linking Error :LNK2020 LNK2019
问题描述
我正在尝试调试VC ++程序.我猜想它是用VC ++ 8.0编码的，而我使用的是VC ++ 2005 EE.
i'm trying to debug a VC++ program. I guss it was coded in VC++ 8.0 and i am using VC++ 2005 EE.
我很确定我已经包含了所有的库文件.
I'm pretty sure that i have included all the library files.
这是代码:

我已经阅读了几篇文章，并被告知我们需要使用析构函数，因此我对代码进行了一些修改(我不知道它是对还是错)
i've read a few articles and i've been advised that we need to use a distructor so i modified the code a bit ( I dont know if it is Right or Wrong )

我已经在互联网上寻找解决方案将近3天了……请帮助！！！
I've been searching for a solution on the internet for almost 3 days now... pleassssee HELP!!!
推荐答案
您的代码之前是:
受保护的是:
Your Code was:
protected:
~Form1(){
if(components){
delete components;
this->!Form1();
}
}
!Form1();
I think you should use "!Form1();" before "}" like below code:
protected:
~Form1(){
if(components){
delete components;
this->!Form1();
}
!Form1();
}
