Symbian下ini檔案操作

 

Symbian下ini檔案的操作

程式中的一些配置資訊，可以利用ini檔案儲存體。同時儲存到安裝程式的私人路徑下面。

 

_LIT(KtxDicFileName,"settings.ini" );

 

const TInt KRegistrar= 2;

const TInt KUsername= 3;

const TInt KPassword= 4;

一些資料通過流方式的讀取 // String
TBuf<100> iText;
aStream >> iText;
 
// Integer
TInt iVolume;
iVolume = aStream.ReadInt32L();
 
// Boolean
TBool iBinary;
iBinary = aStream.ReadInt16L();
 
// Ip address
TInetAddr iIpAddress;
iIpAddress.SetAddress(aStream.ReadUint32L());
 
// Time
TTime iTime;
TInt64 time;
aStream >> time;
iTime = TTime(time);
