Thank you Tobias and sorry Benoit. Here is a small programme:-
Public hConn As New Connection Public hResult As Result Public Sub _new() With hConn .Type = "MySQL" .Host = "localhost" .Login = "root" .Port = "3306" .Name = "xxx" .Password = "yyy" .Open() End With hResult = hConn.Find("maildata", "DeletedFlag IS NOT TRUE AND Type = 'Received' ORDER BY Date DESC") hResult.MoveFirst End Public Sub btnNext_Click() Dim bTemp As Blob TextBox1.Text = hResult!Date TextBox2.Text = hResult!Address TextBox3.Text = hResult!Subject bTemp = hResult!MsgBlob Print bTemp.Length CheckAttachments(bTemp) hResult.MoveNext End Private Function CheckAttachments(sBody As Blob) File.Save("~/aaa", hResult!MsgBlob) End This gives a segmenation error, in this case when bTemp.Length = 1246339 Other records with small values of bTemp don't cause a problem.
