Windows下如何获取除以零 这种错误?
还有就是如果设置一个进程的最大占用时间

[Y___Y]

使用异常处理

[jacknes009]

使用异常处理
int a=10;
int b=0;
int c;
try
{
c=a/b;
}
catch(EDivByZero &e)
{
ShowMessage(e.Message);//错误处理
}

//在主窗体中建一个函数。

void __fastcall Tfor_Plus::AppLevelExceptionHandle(TObject *Sender,Exception *E);

在每个窗体的OnCreate事件中写入
Application->OnException = for_Plus->AppLevelExceptionHandle;

1.除零异常
int a=10;
int b=0;
int c;
try
{
c=a/b;
}
catch(EDivByZero &e)
{
ShowMessage(e.Message);//错误处理
}

2.根据实际情况Sleep();

[cczlp]

1. 应该改正代码错误, 而不要隐藏错误
2. 设置优先级比正常的低

[hansyswin]

[sakaer]

楼上的所有的楼上的方法都是正确的

[Friecin]

try
{
int a=1, b=0,c;
c=a/b;
}
catch(EDivByZero &e)
{
ShowMessage(e.Message);//错误处理
}

赞成cczlp的观点，不要隐藏错误。
