Error: Stream read error TFileStream *FStream = new TFileStream("C:\somefile.xyz", fmOpenRead || fmShareDenyWrite); String SndText = IdEncoderMIME1->Encode(FStream, FStream->Size); delete FStream; Where is the problem?

When I decode the base64 string to a TFileStream I get corrupted files! Seeing your code you mean: I did base64 encode the contents of a file. And no I try to decode it to a stream.

It is longer yes. But what do contain the first 130677 bytes ? The original file contents ? What is in the result file ? Dit you look in it ? Hans.
