Symbian:change a ringtone programatically in profile-优快云博客

博客围绕Series60平台配置文件编辑展开，提到在Series60 1.0版本可行，但N6600或S60 Platform 2.0不行。还指出在6630手机的特定目录找到配置文件，部分解析了文件格式，不过对校验和构建及错误情况存疑。

Include <profileApi.h> and link with ProfileEngine.lib
Code:

_LIT(KProfileDatabase,"c://system//Apps//profileApp//dbProfile.db");
_LIT(KGeneral,"PRS0");
_LIT(KRingtone,"c://system//data//profiles//ring.mid")

CPermanentFileStore* fstore = CPermanentFileStore::OpenLC(CEikonEnv::Static()->FsSession(),KProfileDatabase,EFileRead|EFileWrite);

RDbStoreDatabase database;
database.OpenL(fstore,fstore->Root());
RDbTable table;
table.Open(database, KGeneral);
table.FirstL();
table.UpdateL();
TDbColType colType = table.ColType(5);

if ((!table.IsColNull(5)) && (colType == EDbColLongText))
{
RDbColWriteStream writeStream;
writeStream.OpenL(table, 5);
writeStream.WriteL(KRingtone());
writeStream.Close();
table.PutL();
}
table.Close();
database.Close();
store->CommitL();
CleanupStack::PopAndDestroy(store);

this will only work with Series60 platform 1.0 it doesn't work with N6600 or S60 Platform 2.0 Phones

I'm trying to edit the profiles in a series 60 >1.0 too, and I found them in seperate files (for every profile) in the C:/System/Data/Profiles directory of my 6630. I decoded the format partly (see below), I have no idea how the checksum should be constructed though, and what happens if it's not correct. Who can help me?
