c++builder如何访问注册表

[wld2003]

各位老大，c++builder如何访问注册表

[牧牛人软件]

#include <registry.hpp>

读：


AnsiString Sno, Year;
int ret;

MainForm->RegistryStat=0;
const String RegKey = "\\SoftWare\\WGHSoftware\\School";
TRegistry *MyRegistry = new TRegistry();
MyRegistry->RootKey = HKEY_LOCAL_MACHINE;
try {
if(MyRegistry->OpenKey(RegKey, false)) {
RegCode=MyRegistry->ReadString("SN");
Unit=MyRegistry->ReadString("UnitName");
SysName=MyRegistry->ReadString("SystemName");
SysCaption=MyRegistry->ReadString("SystemCaption");
MyRegistry->CloseKey();
}
}

catch(ERegistryException &E) {
ShowMessage(E.Message);
delete MyRegistry;
return;
}



写：


const String RegKey = "\\SoftWare\\WGHSoftware\\School";
TRegistry *MyRegistry = new TRegistry();
MyRegistry->RootKey = HKEY_LOCAL_MACHINE;
try {
if(MyRegistry->OpenKey(RegKey, true)) {
MyRegistry->WriteString("UnitName",UnitEdit->Text);
MyRegistry->WriteString("SN",RegCodeEdit->Text);
MyRegistry->WriteString("SystemName",SysNameEdit->Text);
MyRegistry->CloseKey();
}
}
catch(ERegistryException &E) {
ShowMessage(E.Message);
delete MyRegistry;
return;
}
delete MyRegistry;
ShowMessage("注册成功!");
Label1->Caption="已注册";

#include <Registry.hpp>
TRegistry* Reg= new TRegistry;
try
{
Reg->RootKey=HKEY_CURRENT_USER;
if(Reg->OpenKey("\\Software\\MySoft",FALSE)==FALSE)
{
Reg->CreateKey("\\Software\\MySoft");
Reg->OpenKey("\\Software\\MySoft",true);
Reg->WriteInteger("MyKey",123);
}
}
__finally
{
Reg->CloseKey();
delete Reg;
}
