分享急！请教TList如何释放内存
因为函数返回值太多，所以用指针存放了起来，但是并没有传给TreView或者TListView结果无法删除指针了,而是传到clist中了(TList *clist=new TList)。
后来我看帮助说TList的Clear可以释放内存就写了上去，可是好像不起作用啊:(
多谢大家，今晚一定要帮帮我，我昨天晚上就已经通宵了:(

“函数返回值太多”与“TListView”有什么关系？

BCB TList Help:
typedef struct AList
{
int I;
char C;
} TAList;
typedef TAList* PAList;
void __fastcall TForm1::Button1Click(TObject *Sender)
{
PAList AStruct;
TList *MyList = new TList;
// do something
// Clean up ?must free memory for the items as well as the list
for (int i = 0; i < MyList->Count; i++)
{
AStruct = (PAList) MyList->Items[i];
delete AStruct;
}
delete MyList;
}
typedef struct AList

你是不是应该先释放List中每个Item所指向内存，然后再调用clear

Delete clist;
clist = NULL;
clist = NULL;

函数返回值太多,可以用结构啊。
“用指针存放起来”？？不懂ing .
