23.3rd你要想调试控制台，就在epoc.ini里面加上textshell
24.//得到IAP ID_LIT(KIapIdSettingName, "IAP//id");
// start a test connectionRSocketServ socketServ;User::LeaveIfError(socketServ.Connect());CleanupClosePushL(socketServ);
RConnection connection;User::LeaveIfError(connection.Open(socketServ));CleanupClosePushL(connection);
User::LeaveIfError(connection.Start());
// get the IAP IDTUint32 iapId;User::LeaveIfError(connection.GetIntSetting(KIapIdSettingName, iapId));
CleanupStack::PopAndDestroy(2); // connection, socketServ
25.// Get the application UI from CEikonEnvCYourApplicationAppUi* appui = (static_cast<CYourApplicationAppUi*>(iEikonEnv->AppUi()));// Get the view you wantCSomeView* view = (CSomeView*)appui->View(TUid::Uid(ESomeViewId));
26.设置全屏SetExtentToWholeScreen();//and in the void HandleResourceChange( TInt aType );if (ETrue) { SetExtentToWholeScreen(); } else { if (aType == KEikDynamicLayoutVariantSwitch) { TRect mainPaneRect; AknLayoutUtils::LayoutMetricsRect( AknLayoutUtils::EMainPane, mainPaneRect ); SetRect(mainPaneRect); } }
27.CBA//#include <avkon.rsg>SwitchCbaL(TInt aResourceId) { if (aResourceId == 0) aResourceId = R_AVKON_SOFTKEYS_OPTIONS_EXIT; CEikButtonGroupContainer* cba = Cba(); cba->SetCommandSetL(aResourceId); cba->DrawNow(); }
HandleCommandL(TInt aCommand) { switch ( aCommand ) { case EVRexCmdAppReturn: { DoReturnL(); break; } case EVRexCmdAppRecord: { DoRecordL(); break; } .... } }//in rssRESOURCE CBA r_vrex_pause_stop { buttons = { CBA_BUTTON { id=EVRexCmdAppPause; txt = qtn_vrex_pause; }, CBA_BUTTON { id=EVRexCmdAppStop; txt = qtn_vrex_stop; } } ; }RESOURCE CBA r_vrex_continue_return { buttons = { CBA_BUTTON { id=EVRexCmdAppContinue; txt = qtn_vrex_continue; }, CBA_BUTTON { id=EVRexCmdAppReturn; txt = qtn_vrex_return; } } ; }...
28.//文件系统的简单使用BaflUtils::PathExists()BaflUtils::FileExists()
29.//手机屏幕大小TPixelsTwipsAndRotation pixTwipsRot; CCoeEnv::Static()->ScreenDevice()->GetDefaultScreenSizeAndRotation(pixTwipsRot); TSize screensize = pixTwipsRot.iPixelSize;
30.指定大小内存清空Mem::FillZ（）;
31.当要进行的操作是最急需处理的，即使UI事件也不能中断它，可以将本线程设为最高优先级：RThread().SetPriority( EPriorityAbsoluteHigh );......RThread().SetPriority( EPriorityLess );
32.将8位字符填充到16位字符中TInt16* aBuffer;TInt8* p;//add contentsaBuffe全为将p第j个8位字符填充到为空值的aBuffer中第i个16位字符中
33.线程中自己创建清除栈创建了还不行，需要至少一个TRAP或TRAPD TInt Fun( TAny* aPtr ){ CTrapCleanup* cleanup = CTrapCleanup::New(); //判断是不是为空，不为空进入下一步 TRAPD( err, DoThread( aPtr ) ); delete cleanup; return 0;}
34.位图操作（读写位图，改变位图）TBitmapUtil 直接操作数据区：比如：你要自己处理像素数据，处理图像。使用数据区，是不是只能读和修改，不能增加数据。Symbian中操作图片时，一般大于4K的图片，需要锁住图片内存 TBitmapUtil bmpUtil( iOffScrnBmp );bmpUtil.Begin( TPoint( 0, 0 ) );pData = (TUint8*)iOffScrnBmp->DataAddress();bmpUtil.End();
35.读取文件内容到内存中HBufC8* C×××Container::ReadFileLC(const TDesC& aFileName) { RFs rfs; RFile file; User::LeaveIfError(rfs.Connect()); CleanupClosePushL(rfs); User::LeaveIfError(file.Open(rfs, aFileName, EFileRead)); CleanupClosePushL(file); TInt size; User::LeaveIfError(file.Size(size)); HBufC8* buf = HBufC8::NewLC(size); TPtr8 bufPtr(buf->Des()); User::LeaveIfError(file.Read(bufPtr)); CleanupStack::Pop(); // buf CleanupStack::PopAndDestroy(2); // file, rfs CleanupStack::PushL(buf); return buf; }
36.模拟按键 RWsSession ws; ws.Connect(); TRawEvent ev1; ev1.Set(TRawEvent::EKeyDown, EStdKeyYes); ws.SimulateRawEvent(ev1); // CAPABILITY Req. SwEvent //User::After(1000000); TRawEvent ev2; ev2.Set(TRawEvent::EKeyUp, EStdKeyYes); ws.SimulateRawEvent(ev2); ws.Flush(); ws.Close();
37。桌面主程序即UID3为0x101FD64C（idle.exe)
38.检查盘符内存是否够用 TVolumeInfo volinfo; TInt err=iFs.Volume(volinfo,EDriveC);//检查c盘下面剩余空间 if ( volinfo.iFree<(iFrameCount*iFrameSize)) { //enough ｝
devicesdevices -setdefault @****bldmake bldfilesabld build armi urel再在Carbide c++中编译sis
1、程序安装完后自启动设置：PKG文件中，执行文件（app/ exe）后面加上：FR, RI，并且放在安装文件列表的最后一个，等所有资源安装后再自启动。例：****.app",FR,RI
2、三版写文件的一种方法。TFileText，逐行读取数据。RFs fs;RFile iFile;User::LeaveIfError(fs.Connect());iFile.Open(fs,KFilename,EFileRead|EFileShareAny);TFileText lineRead;lineRead.Set(iFile);lineRead.Seek(ESeekStart);TBuf<256> temp;lineRead.Read(temp);......lineRead.Read(temp);......iFile.Close;fs.Close;
/// RFs fs; fs.Connect(); RFile file; _LIT(KFilename,"c://weather.xml");// if(BaflUtils::FileExists(fs,KFilename))// {// file.Replace(fs,KFilename,EFileStreamText|EFileWrite|EFileShareAny);// }// else // {// file.Create(fs,KFilename,EFileWrite|EFileShareAny);// }// file.Write(0,iFeedText); file.Open(fs,KFilename,EFileRead|EFileShareAny); file.Read(iFeedText); file.Close(); fs.Close();3、在类的const函数中使用并改变类的普通变量的值.
void CClassU::Draw(const TRect& aRect) const{((CClassU*)this)->index = 0;//index是CClassU类的普通变量
}
4.TInt CCallElfAppUi::cInt(const TDesC& aStrInt){TBuf8<10> aNum;aNum.Copy(aStrInt);TLex8 lex8(aNum);TInt iNum;TInt ret = lex8.Val(iNum);if (ret != KErrNone){return 0;}else{return iNum;}}
5.和C++没有区别~ 按位非 ~expr<< 左移 expr1 << expr2>> 右移 expr1 >> expr2& 按位与 expr1 & expr2^ 按位异或 expr1 ^ expr2| 按位或 expr1 | expr2&= 按位与赋值 expr1 &= expr2^= 按位异或赋值 expr1 ^= expr2|= 按位或赋值 expr1 |= expr2
6.快捷使用方法template <class T>inline TBool Rng(T aMin,T aVal,T aMax) {return(aVal>=aMin && aVal<=aMax);}
7.手机桌面UID/*SDK UID Process Name2nd edition 0x100058b3 （Phone）3rd edition 0x100058b33rd edition and 3rd edition FP1 0x101fd64c （Standby Mode）3rd edition FP2 0x102750F0 （Standby Mode）5th edition 0x102750F0 */
