CB5.0中定义一个结构体:
struct SwitcherPorts
{
char UserName[50];
char PassWord[50];
char OtherSettings[100];
};
lstrcpy(SwitcherPorts->UserName,"test11");
SwitcherPorts->UserName始终为空?

SwitcherPorts Tmp;
lstrcpy(Tmp.UserName,"test11");
或者
SwitcherPorts *Tmp = new SwitcherPorts;
lstrcpy(Tmp->UserName,"test11");

只定义了类型，没有申明变量，如何赋值

小笨苯的答案基本正确，zhu_jy的解释合情合理。
SwitcherPorts Tmp;
// 完全正确
lstrcpy(Tmp.UserName,"test11");
或者
SwitcherPorts *Tmp = new SwitcherPorts;
if (Tmp != NULL) // BCB中new失败可能会抛出异常（默认），也可能返回NULL，VC中默认返回NULL
lstrcpy(Tmp->UserName,"test11");
