Eu não descobri o que causa isso, mas descobri um remédio fazendo uma consulta de exclusão primeiro e depois inserindo dados.
SQLStr = "delete FROM [Patient_Data].[dbo].[tbPatientImage] where HospNum='" & Session.Item("HospNum") & "'" & _
" and IDNum='" & Session.Item("IDNum") & "' and FileType= '" & lblHeader.Text & "'"
Dim cmd As New SqlCommand(SQLStr, con)
cmd.Connection = con
con.Open()
cmd.ExecuteNonQuery()
SQLStr = " INSERT INTO [Patient_Data].[dbo].[tbPatientImage](HospNum,IDNum, DoctorID, PatImage , FileType, FileName, FileSize , TransDATE) " & _
" VALUES (@HospNum,@IDNum, @DoctorID, @Data, @FileType, 'Patient Photo' , @FileSize, GETDATE())"
cmd.CommandText = SQLStr
'cmd.CommandTimeout = 120
cmd.Parameters.AddWithValue("@HospNum", Session.Item("HospNum"))
cmd.Parameters.AddWithValue("@IDNum", Session.Item("IDNum"))
cmd.Parameters.AddWithValue("@DoctorID", Session.Item("DoctorID"))
cmd.Parameters.AddWithValue("@FileType", lblHeader.Text)
cmd.Parameters.AddWithValue("@FileSize", FileSizeOfIMG)
cmd.Parameters.Add(ImageTypeDataOfImage)
cmd.ExecuteNonQuery()
con.Close()
GetData()
lblMessage.Text = "Saved."
End Using
End Sub
