在运行期间检查S60平台版本

CS000933

• 开发伙伴平台：

S60 3rd Edition, MR

S60 3rd Edition, FP2

• 详细描述

下列代码演示了如何在运行时检测S60平台的版本，这里提供了两个不同的方法，一个为S60第三版FP2之前版本的解决方案，一个为S60第三版FP2手机的解决方案。第一个方法检查安装在手机中的SIS文件的版本号，第二个方法是用S60第三版FP2中的Version Info API方法。

下列代码只需自签名即可执行

[edit]MMP文件

第一个方法要使用TFindFile，需要下列链接库

LIBRARY  efsrv.lib

第二个方法是用VersionInfo，需要如下链接库

LIBRARY  platformver.lib

[edit]源文件:使用TFindFile

#include <f32file.h>  // TFindFile// On return, aMajor and aMinor contain the highest version number found 
 
from
// the .sis file names
void GetS60PlatformVersionL(RFs& aFs, TUint& aMajor, TUint& aMinor)
    {
    TFindFile fileFinder = aFs;
    CDir* result;
 
    _LIT(KS60ProductIDFile, "Series60v*.sis");
    _LIT(KROMInstallDir, "z:\\system\\install\\");
 
    User::LeaveIfError(fileFinder.FindWildByDir(KS60ProductIDFile,
            KROMInstallDir, result));
    CleanupStack::PushL(result);
 
    // Sort the file names so that the newest platforms are first
    User::LeaveIfError(result->Sort(ESortByName | EDescending));
 
    // Parse the version numbers from the file name (e.g. Series60v3_1.sis)
    aMajor = (*result)[0].iName[9] - '0';
    aMinor = (*result)[0].iName[11] - '0';
    CleanupStack::PopAndDestroy(result);
    }// Connect to the file server session
RFs fsSession;
User::LeaveIfError(fsSession.Connect());
CleanupClosePushL(fsSession);
 
// Obtain the version number
TUint major;
TUint minor;
GetS60PlatformVersionL(fsSession, major, minor);
CleanupStack::PopAndDestroy();  // fsSession
 
// Display the version number
TBuf<255> buffer;
_LIT(KTxt, "Version: %d.%d");
buffer.Format(KTxt, major, minor);
CAknInformationNote* note = new (ELeave)CAknInformationNote(ETrue);
note->ExecuteLD(buffer);

[edit]源文件:使用VersionInfo

#include <versioninfo.h>  // VersionInfo// On return, aMajor and aMinor contain the version information
TInt GetS60PlatformVersionL(RFs& aFs, TUint& aMajor, TUint& aMinor)
    {
    VersionInfo::TPlatformVersion platformVersion;
    TInt ret = VersionInfo::GetVersion(platformVersion, aFs);
    if (ret == KErrNone)
        {
        aMajor = platformVersion.iMajorVersion;
        aMinor = platformVersion.iMinorVersion;
        }
    return ret;
    }// Connect to the file server session
RFs fsSession;
User::LeaveIfError(fsSession.Connect());
CleanupClosePushL(fsSession);
 
// Obtain the version number
TUint major;
TUint minor;
User::LeaveIfError(GetS60PlatformVersionL(fsSession, major, minor));
CleanupStack::PopAndDestroy();  // fsSession
 
// Display the version number
TBuf<255> buffer;
_LIT(KTxt, "Version: %d.%d");
buffer.Format(KTxt, major, minor);
CAknInformationNote* note = new (ELeave)CAknInformationNote(ETrue);
note->ExecuteLD(buffer);

注意上述方法只能用于S60第三版FP2及后继机型
