Could you please write here sample test case and definition of your table ? I could't reproduce the bug.

Description: I make use of ByteFX.Data Class Library to connect mysql in .NET application. The table contains 2 mediumblob columns. The same method to select some columns from the table. Query 1 without mediumblob column while Query 2 contains mediumblob column. Query 1 succeed but query 2 failed: Index and count must refer to a location within the buffer.\r\nParameter name: bytes SealPicture and SealData are mediumblob columns. Without this 2 column in the select statement, this method works. The code I wrote: string sql = "SELECT SealID, SealPicture,SealData,SealType,SealName,SealColor FROM SealInfo WHERE SealID=@SealID"; MySqlParameter sealIDParam = new MySqlParameter("@SealID", MySqlDbType.VarChar, 50); sealIDParam.Value = sealId; try { reader = MySqlHelper.ExecuteReader(CONNECTION_STRING, sql, sealIDParam); if (reader.Read()) { ...... } How to repeat: 1. Create a table with mediumblob colum 2. Insert some data 3. Use ByteFX.Data Class Library to read it like what I did in the above description Suggested fix: As soon as possible, we will release the product very soon.
