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
