原来C++Builder6在XP下获取串口的方法:

void
TTools::GetSystemPortList(TStringList * pList)
{
TRegistry *regkey=
new
TRegistry();
pList->Clear();
regkey->RootKey=HKEY_LOCAL_MACHINE;
TStringList *KeyNames;
KeyNames=
new
TStringList();
regkey->OpenKey(
"HARDWARE\\DEVICEMAP\\SERIALCOMM"
,
false
);
regkey->GetValueNames(KeyNames);
for
(
int
i=0;i<=(KeyNames->Count-1);i++)
{
AnsiString a = regkey->ReadString(KeyNames->Strings[i]);
pList->Add(a);
}
regkey->CloseKey();
delete
KeyNames;
delete
regkey;
}

这种方法,编译好的程序,在Win10下无效,需要管理员权限执行才行.
在Win10直接用API读注册表获取,代码如下:
