1、获取IMSI号、手机版本等
CTelephony：GetSubscriberId()
CTelephony：GetPhoneId()
CTelephony：Version()
TSize CEikConsoleScreen::ScreenSize
方法1：
_LIT(KFontName,"Courier");
TFontSpec fontSpec;
fontSpec.iTypeface.iName=KFontName;
fontSpec.iFontStyle.SetStrokeWeight(EStrokeWeightBold);
fontSpec.iHeight=100;
CFont * iFont;
CCoeEnv::Static()->ScreenDevice()->GetNearestFontInTwips(iFont,fontSpec);
CColumnListBoxData * data =
( static_cast<CColumnListBoxItemDrawer*>
(iListBox->ItemDrawer()))->ColumnData();
data->SetColumnFontL(1,iFont);
方法2：
data->SetColumnFontL(1,LatinPlain12());
方法3：
const CFont * iFont1;
const CFont * iFont2;
iFont1 = AknLayoutUtils::FontFromId(EAknLogicalFontPrimaryFont);//大字体
iFont2 = AknLayoutUtils::FontFromId(EAknLogicalFontPrimarySmallFont);//小字体
data->SetColumnFontL(1,iFont2);
注意以上方法都必须在ActiveL()后面（也就是必须List创建好了）再使用.

在*.pkg文件中，'-'前面是PC上的文件目录，请确认PC上对应目录下存在这些文件。
'-'后面是手机上的目录，采用相对路径，如“resource/apps/*.mbm”
注意：程序中若加载*.mbm文件中图片，需要使用“resource//apps//*.mbm”，注意'//'。
6、经常出现的SetRect(aRect);或ActivateL();出现错误
需要注意控件是否成功构造。
通常是由于构造函数中的代码次序问题。控件的构造应该在 ActiveL前完成。
Capabilities for the certificate

打包：makesis *.pkg *.sis

移植第三方代码的时候注意能力选项，如获取手机IMSI号需要ReadDeviceData能力。
修改rss文件后保存了需要重新编译项目，否则可能出现增量编译导致程序运行时加载字符串等资源出错。
直接将类对象作为另外某个类的成员变量，而不是将该类对象指针作为类的成员变量，那么如果该类的构造函数是Protected/Private的，则新的对象无法成功构造！
13、RArray<Templete>定义时Templete的大小不能超过640
报告User 129错误， 127错误也是由RArray引起。
TMemoryInfoV1Buf info;
UserHal::MemoryInfo(info);
TInt freeMemory = info().iFreeRamInBytes;
void CTestDlgDialog::PrepareLC(TInt aResourceId)
{
CEikDialog::PrepareLC( aResourceId );
// Pick up the Editor control from the dialog
CEikEdwin* control = static_cast<CEikEdwin*>(ControlOrNull(EMyQuery));
// Set the input mode
control->SetAknEditorInputMode(EAknEditorNumericInputMode);
// Restrict the other input modes
control->SetAknEditorAllowedInputModes(EAknEditorNumericInputMode);
}
const TInt KSnapSoundId = 2;
CAknKeySoundSystem* iCameraSound;
iCameraSound = static_cast<CAknAppUi*>(CEikonEnv::Static()->AppUi())->KeySounds();
if (iCameraSound)
{
TRAPD(error, iCameraSound->AddAppSoundInfoListL(R_CAMERA_SNAP_SOUND));
if ((error != KErrAlreadyExists) && (error != KErrNone))
{
User::LeaveIfError(error);
}
}
iCameraSound->PlaySound(KSnapSoundId);
//以下在rss文件中定义
#define KcameraSoundFile "Z://system//sounds//digital//Camera1a_2_8kHz.wav"
#define KSnapSoundId 2
RESOURCE AVKON_SOUND_INFO_LIST r_camera_snap_sound
{
list =

AVKON_SOUND_INFO
{
sid = KSnapSoundId;
priority = 45;
preference = EAknAudioPrefCamera; // defined in avkon.hrh
file = KCameraSoundFile;
}
};
}
#include <rconnmon.h>
void CWlanTest:: ListNetworksAndSignalL(CDesCArraySeg& aNetworks)

_LIT(KNetInfo, "Network: %S/tSignal: %d");
TBuf<32> netName;
TBuf<100> line;
RConnectionMonitor monitor;
TPckgBuf<TConnMonNetworkNames> pkgNetworks;
// establish connection with the monitor server
monitor.ConnectL();
// prepare leave clean-up
CleanupClosePushL(monitor);
TRequestStatus status;
// get the list of available networks
monitor.GetPckgAttribute(EBearerIdWLAN, 0, KNetworkNames, pkgNetworks, status);
// suspend thread until the info is retrieved
// production code should use active objects
User::WaitForRequest( status ) ;
// leave if the asynchronous method returned an error
User::LeaveIfError(status.Int());

line.Format(KNetInfo, &netName, pkgNetworks().iNetwork[i].iSignalStrength);
aNetworks.AppendL(line);
}
// close server session
CleanupStack::PopAndDestroy(&monitor);
}
Note:
- Link against: ConnMon.lib
- S60 3rd Edition-specific capability needed: NetworkServices
参考CVideoPlayerUtility的使用，可以播放流内容，详情参考SDK
问题一：更换S60第三版的应用程序图标
在mmp文件中添加
START BITMAP Test_aif.mbm
TARGETPATH /resource/apps
HEADER
SOURCEPATH ../data
source c24 icon_lst.bmp
source c24 icon_lst_mask.bmp
source c24 icon_cxt.bmp
source c24 icon_cxt_mask.bmp
END
修改rss文件中LOCALISABLE_APP_INFO
icon_file = "//resource//apps//Test_aif.mbm";
在pkg 文件中增加
"C:/Symbian/9.1/S60_3rd_MR/Epoc32/data/z/resource/apps/Test_aif.mbm"-"!:/resource/apps/Test_aif.mbm"
问题二：模拟器无法启动
可能由于部分注册应用造成，尝试删除些*_reg.*
问题三：图片读取转化及base64解码问题
Base64使用TImCodecB64 类
图片注意DataNewL的数据必须作为成员变量，而不是局部变量，保证在转化之前数据未丢失
问题四：屏蔽HTTP接入点
步骤一：列举接入点
http://www.newlc.com/A-few-notes-about-the-CommDb.html
CCommsDatabase* CommDb = CCommsDatabase::NewL(EDatabaseTypeIAP);
CleanupStack::PushL(CommDb);
CApSelect* ApSelect = CApSelect::NewLC(*CommDb, KEApIspTypeAll ,EApBearerTypeAll ,KEApSortUidAscending);
if (ApSelect->MoveToFirst())
{
do{
TUint uid = ApSelect->Uid();
//put here your IAP stuff
}while(ApSelect->MoveNext());
}
CleanupStack::PopAndDestroy(ApSelect);
CleanupStack::PopAndDestroy(CommDb);
步骤二：
//头文件
RHTTPSession iSession;
RHTTPTransaction iTransaction;
RConnection iConnection;
RSocketServ iSocketServ;
//构造中
User::LeaveIfError(iSocketServ.Connect());
User::LeaveIfError(iConnection.Open(iSocketServ));
iPref.SetDialogPreference(ECommDbDialogPrefDoNotPrompt);
iPref.SetIapId(IAPId);
iPref.SetBearerSet(KCommDbBearerPSD);
iPref.SetDirection(ECommDbConnectionDirectionOutgoing);
TInt ret;
if( ( ret = iConnection.Start(iPref)) != KErrNone)
{
//成功了
}
//打开会话成功
TRAPD(err, iSession.OpenL());
步骤三：将http绑定到指定SocketServ，在http Post中
http://www.forum.nokia.com/document/Forum_Nokia_Technical_Library/contents/FNTL/Using_the_HTTP_Client_API_with_RConnection.htm
User::LeaveIfError(iSocketServ.Connect());
User::LeaveIfError(iConnection.Open(iSocketServ));
iHttpSession.OpenL();
// Initiate connection
iConnection.Start(iStatus);
//...
RHTTPConnectionInfo connInfo = iHttpSession.ConnectionInfo();
RStringPool pool = iHttpSession.StringPool();
// Attach to socket server
connInfo.SetPropertyL(pool.StringF(HTTP::EHttpSocketServ, RHTTPSession::GetTable()), THTTPHdrVal(iSocketServ.Handle()));
// Attach to connection
TInt connPtr = REINTERPRET_CAST(TInt, &iConnection);
connInfo.SetPropertyL(pool.StringF(HTTP::EHttpSocketConnection, RHTTPSession::GetTable()), THTTPHdrVal(connPtr));
// Open transaction...
iHttpTrans = iHttpSession.OpenTransactionL(iUri, *this, pool.StringF(HTTP::EGET, RHTTPSession::GetTable()));
RHTTPHeaders hdr = iHttpTrans.Request().GetHeaderCollection();
问题五：如何在Container中List控件和图片控件切换
void CMyContainer::Draw(TRect aRect)
{
CWindowGc& gc = SystemGc();
gc.SetPenStyle( CGraphicsContext::ENullPen );
gc.SetBrushColor( KRgbGray );
gc.SetBrushStyle( CGraphicsContext::ESolidBrush );
gc.DrawRect( aRect );
if(iImage)
{
gc.Clear();
gc.BitBit(TPoint(0,0), iImage);
}
}
CCoeControl* CMyContainer::ComponentControl(TInt aIndex) const
{
switch(TInt nIndex)
{
case 0:
if(iImage)
iListBox->MakeVisue(EFalse);
else
iListBox->MakeVisue(ETrue);
}
}
void CMyContainer::ShowImage()
{
iImage = ***;
DrawNow();
}
问题六：关于手机上的Log日志
现在在手机上，用PC套件怎么只能看到手机的Data目录，C:/Logs/MyLogDir/Log.txt看不到
1）退出时读文件内容重写一个新文件到Data目录
2) 安装文件工具FExplorer，http://www.newlc.com/article.php3?id_article=70
3） 使用自定义log http://developer.uiq.com/forum/threa...=1120&tstart=0
问题七：中文字符处理问题
Java String 16 中文 ->> 客户端8bit接受 --> 转化为16bit Tbuf, OKOK!
客户端16bit Tbuf --> 转化为8bit发送 --> Java String接受为乱码？？？？？
解决: 使用utf.h中的C**Convert函数转化，而不是使用Copy函数
问题八：对话框被覆盖
使用CAknInformationNote的R_AKN_INFORMATION_NOTE_WAIT 标志
问题九：制作mask图片
直接将文件存为黑白图片即可
问题十：如何保证让http接收完成后再进行后续操作
1）使用观察器
2）使用等待框
