RootKey是注冊表的根鍵值,比如運行regedit後看到的HKEY_USERS,HKEY_LOCAL_MACHINE就是RootKey,在TRegIniFile中缺省的RootKey是HKEY_USERS.
下面的例子是TRegistry的,TRegIniFile也差不多
void __fastcall TfrmMainForm::WriteToMyRegistry(int table_count)
{
//TODO: Add your source code here
TRegistry *MyRegistry=new TRegistry;
MyRegistry->RootKey=HKEY_LOCAL_MACHINE;
//改變缺省Rootkey
if(!MyRegistry->OpenKey("Software\\Microsoft\\Windows\\Current\
Version\\Run",true)) //打開主鍵
//這樣雙引號裡面的東西就變成了CurrentKey
{
Application->MessageBox("注冊表內容無效",
"讀取注冊表出錯",MB_ICONERROR);
MyRegistry->CloseKey();
delete MyRegistry;
return;
}
MyRegistry->WriteString("myrun","c:\\sthvcd\\sthvcd.exe");
MyRegistry->CloseKey();
delete MyRegistry;
