Type "Binary" not supported

reijermolenaar

Hi,

When I compile an object I get the following warning:

Type "Binary" not supported

I use a variable of type Binary to read one bit from a stream like this:

InStr.READ(Bin1);

Does anybody know how I can do this without the use of a binary?

Use Char. You will read 8 bits, you can extract the bits by "div 2" and "mod 2".

Hi Kine,

Thanks, but that will be dramatic for the performance.


I will try to explain what I am doing…

I have a file (a kind of a backup file) with data in it. It also includes the values of blobfields. So when I import this file I have to transfer parts of this instream in different blob fields. (e.g. item.picture)

Now when I want to transfer 1000 bytes from that InStream to an OutStream I do the following:

InStr.READ(Bin1000);
OutStr.WRITE(Bin1000);

If I have to use a Char to do this like this it will be very slow:

FOR i := 1 TO 1000 DO BEGIN
  InStr.READ(Char1);
  OutStr.WRITE(Char1);
END;

Let me rephrase my question:

What is the fastest way to transfer a variable no. of bytes from one stream to another?

Thanks for your time!
