關(guān)于C++builder編程修改注冊(cè)表的問題

字號(hào):

RootKey是注冊(cè)表的根鍵值,比如運(yùn)行regedit后看到的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?nèi)笔ootkey
     if(!MyRegistry->OpenKey("Software\\Microsoft\\Windows\\Current\Version\\Run",true)) //打開主鍵
        //這樣雙引號(hào)里面的東西就變成了CurrentKey
        {
          Application->MessageBox("注冊(cè)表內(nèi)容無效", "讀取注冊(cè)表出錯(cuò)",MB_ICONERROR);
          MyRegistry->CloseKey();
          delete MyRegistry;
          return;
         }
       MyRegistry->WriteString("myrun","c:\\sthvcd\\sthvcd.exe");
       MyRegistry->CloseKey();
       delete MyRegistry;
