Externalise TInt64

[76Richard76]

My app needs to store some Date/Time values to a file. If I use RFileWriteStream to do :-

TInt64 MyTInt64 = 0;
writer << MyTInt64;

I get a compilation error :-

Severity Description Resource In Folder Location Creation Time Id
2 expression syntax error (point of instantiation: 'scWriteMainFileL()') (instantiating: 'operator <<<int>(RWriteStream &, const int &)') (instantiating: 'DoExternalizeL<int>(const int &, RWriteStream &, Externalize::Member)') sc21 line 290 04 April 2007 11:04:02 947

The line number is not related to the source file line, and it took a lot of guesswork to find out that it is only writing a TInt64 that gives a problem, not a TBuf or TInt.

The Carbide help system says :-

"Implementation for standard types and classes
The Store framework provides the necessary implementation for the operators to externalise and internalise the following:

The basic types: TInt8, TInt16, TInt32, TInt64, TUint8, TUint16, TUint32, TReal32 and TReal64.
The graphics API classes: TPoint, TSize and TRect.
The UID Manipulation API class: TUid.
The Dynamic Buffers API classes: CBufFlat and CBufSeg."

So I think that my code SHOULD work. Please tell me if I am wrong...


How should I progress this problem? My C++ knowledge is poor, I am still in the 'struggle stage', some help would be appreciated.

Sorry about that, I WAS wrong, I had put a TInt into my struct that I was trying to write away, and of course that doesn't work with operator <<.

Apologies
