How to serialize multidimensional CArray objects?

I have developped an application that uses multidimensional CArray objects. I need to save these arrays and I haven't found the way to do it. The CArrays contain mainly double numbers.
Tle arrays are initialized so;

typedef CArray <double,int> OneInPattern;
CArray <OneInPattern,OneInPattern&> InPattern;

Any cue?

Thanks

CArray is actually derived from CObject so you can take advantage of Serialize function and << and >> operators

Your declaration is bogus.

You've declared a CArray that uses an index of integers to store doubles, which is natural enough. You've typedef'ed that to be called OneInPattern.  You can do things like this:

   OneInPattern array;
   array[3] = 3.1415929;

You've then declared a CArray that uses an index of references to CArrays and stores other CArrays. That's entirely bogus.

Don't you really mean to code:

   typedef CArray <double,int> OneInPattern;
   CArray <OneInPattern&, int> InPattern;

?  That way, you can do things like this:

   // set [3][5] to 2.17.
   InPattern[3].SetAt(5, 2.17);

I have a full class developed for my own project called CDouble2dArray. With it you can simply create multidimensional double-arrays. If you change to int, word ... you can easily create new multidimensional arrays like CInt2dArray. I can also serialize this multidimensional arrays. If you want the complete .cpp-file send me an email at MKuelsh@aol.com.

Hope this helps
