Later, using a GetChunk which is a Recordset function a number of bytes in OLE object is read but this function just result in the number of printable characters and it discards or ignore for instance, byte 0 or any other not printable character. In the second example, it is possible to see a function to read 20 bytes after a certain position. Now the problem is similar. The 20 bytes has been counted by the results are just printable characters of such 20 bytes. So, result is less than 20 character because not all 20 characters are printable. Reproduce code: --------------- $engine = new COM("DAO.DBEngine.35"); $engine->SystemDB = "c:\system.mda"; $engine->defaultuser = "admin"; $engine->defaultpassword = ""; $db = $engine->OpenDataBase("c:\bd.mdb"); $sqlstr = "SELECT DISTINCTROW tabla1.* FROM tabla1;" ; $rst = $db->OpenRecordset("RsConfig",$sqlstr); echo $rst->Fields["Campo1"]->GetChunk(1,20); //------------------------------------------------- $mstream = new COM("ADODB.Stream"); $mstream->Type = 1; // 'adTypeBinary $mstream->Open; $mstream->Write($rst->Fields["Campo1"]->Value); $mstream->position = 0; echo $mstream->Read(20); Expected result: ---------------- The actual number of bytes in a OLE object stored in a Recordset: This number of bytes of course, must include printable and not printable characters. Actual result: -------------- Just the number of printable characters. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=41388&edit=1
