Saving and loading structures in a file

There is no automatic way to do it. You will need to create two functions. One that writes your structure to the stream and one that reads a structure from the stream.
If it is not clear enough, post your complete structure and I'll write an example.

Hi Erel,

These are my structures, as you can see I have nested some inside the bigger one called "caja" , this one is the one to be saved and loaded on the file.

Type Crossover(TipoHP As Byte,SlopeHP As Byte,FrecHP As Int,TipoLP As Byte,SlopeLP As Byte,FrecLP As Int)

Type GEQ (Bypass As Byte,Level(30) As Byte)

Type PEQ (Level(8) As Byte,BW(8) As Byte,Frec(8) As Int)

Type Limiter (Thres As Byte,Att As Byte, Rel As Byte,Bypass As Boolean)

Type Caja (MuxInA As Byte,MuxInB As Byte,LevelNoise As Byte,LevelInA As Byte,LevelInB As Byte,GEQA As GEQ,GEQB As GEQ,DelayA As Int,DelayB As Int,CrossA As Crossover,CrossB As Crossover,PEQA As PEQ,PEQB As PEQ,LevelOutA As Byte,LevelOutB As Byte,PhaseA As Byte,PhaseB As Byte,LimA As Limiter,LimB As Limiter,Earth As Byte, ID As Byte,IP As String)
'--------------------------------------------------------------------------
Dim Box As Caja

Thanks and regards

See the updated RandomAccessFile library: http://www.b4x.com/forum/additional...sfile-v1-10-read-write-objects.html#post48195
It should be very easy to save and load the types.

Thanks a lot for the update Erel. Just what I needed.:icon_clap:
