Posted on by hubi777x

Hi,
we use BC20 (On Premise).
We currently store files in Azure File Share. When I upload data, I use a stream and HTTP http request methods.
Azure only allows streams up to 4MB. If the stream is larger, it must be split into chunks.

FileName := FileMgt.BLOBImportWithFilter(TempBlob, 'Choose file', FileName, 'All Files (*.*)|*.*', '*.*');
TempBlob.CreateInStream(InStream, TextEncoding::UTF8);

WriteFrom(InStream);

How can is split the InStream into multiple chunks?

Regards

RE: Spilt InStream into chunks

I finaly found a solution by my own

var
CByte: Byte;

// Copy binary data (byte by byte) from InStream into OutStream
Blob1.CreateOutStream(OutStream);
for i := 1 to ChunkSize do begin
InStream.Read(CByte);
OutStream.Write(CByte);
end;

// Copy OutStream to ChunkStream
Blob2 := Blob1;
Blob2.CreateInStream(ChunkInStream, TextEncoding::UTF8);

WriteFrom(ChunkInStream);
