Bug? Bug in RandomAccessFile ?

[Deleted member 103]

Hi,

This code works in B4a without problems.

        Starter.raf.Initialize(File.DirDocuments, "file.txt", False)
        Dim lst As List = Starter.raf.ReadB4XObject(Starter.raf.CurrentPosition)
        Starter.raf.Close

In B4i I have to rebuild "raf" the object every time, otherwise it crashes.

        Dim raf As RandomAccessFile
        raf.Initialize(File.DirDocuments, "file.txt", False)
        Dim lst As List = raf.ReadB4XObject(raf.CurrentPosition)
        raf.Close

Which error do you get?

It is more correct to dim a variable before you initialize it again. There is no reason to use a global variable in this case.

So I have no problem, I've only wondered because in B4a, without re-dimensioning the variable, it does not make any problems.
Question, after "raf.Initialize" the current position "raf.CurrentPosition" should not be zero?

It is zero.

It is zero.

Unfortunately only with B4a.
For B4i, the variable is not zero if the variable "raf" has been defined as a global variable.

You should call Dim again before you initialize it.

You should call Dim again before you initialize it.

Is OK.

It is fixed for the next update of iRandomAccessFile.
