c++builder如何访问注册表

[wld2003]

各位老大，c++builder如何访问注册表

[gdyt007]

首先#include <Registry.hpp>
列舉一下
ReadString
WriteString
GetDateInfo
CreatKey
DeleteKey

[gdyt007]

給你一個例子：
TRegistry *my=new TRegistry;
my->RootKey=HKEY_LOCAL_MACHINE;
my->OpenKey("HARDWARE\\DEVICEMAP\\SERIALCOMM",true);
COMlist->Sorted=false;
my->GetValueNames(COMlist->Items);
COMlist->Items->BeginUpdate();
for(int i=0;i<COMlist->Items->Count;i++)
COMlist->Items->Strings[i]=my->ReadString(COMlist->Items->Strings[i]);
COMlist->Items->EndUpdate();
COMlist->Sorted=true;

#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";

读：
String View;
TRegistry* Reg = new TRegistry;
Reg->RootKey = HKEY_CURRENT_USER; // 主键
if (Reg->KeyExists("Software\\Windows"))
{// 打开键
Reg->OpenKey("Software\\Windows", false);
View= Reg->ReadString("ViewSet");
Reg->CloseKey(); // 关闭键
}
