关于C++builder编程修改注册表的问题

作者:NO1 来源:赛迪网社区 添加时间:2006-5-26 10:34:09

RootKey是注册表的根键值,比如运行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;  //改变缺省Rootkeyif(!MyRegistry->OpenKey("Software\\Microsoft\\Windows\\Current\Version\\Run",true))  //打开主键   //这样双引号里面的东西就变成了CurrentKey   {     Application->MessageBox("注册表内容无效", "读取注册表出错",MB_ICONERROR);     MyRegistry->CloseKey();     delete MyRegistry;     return;    }  MyRegistry->WriteString("myrun","c:\\sthvcd\\sthvcd.exe");  MyRegistry->CloseKey();  delete MyRegistry;
