MySQLConnection.BeginOpen throws NotSupportedException

Hello all,

The following code throws a NotSupportedException:

Code: Select all
    .
    .
    Private connection as MySqlConnection
    .
    .

    Private Sub Connect()
        connection = New MySqlConnection

        connection.UserId = "userid"
        connection.Password = "password"
        connection.Host = "192.168.1.1"
        connection.Database = "localdb"

        Dim delegate_endConnect As New AsyncCallback(AddressOf EndConnect)
        Dim state_object As New Object

        Try
                Dim ar As IAsyncResult = connection.BeginOpen(delegate_endConnect, state_object)
        Catch ex as Exception
                ' Display exception
        End Try
    End Sub

    Private Sub EndConnect(ByVal ar As IAsyncResult)
        connection.EndOpen(ar)

        If ar.IsCompleted = True Then     
            ' Connected
            ' Perform actions...
        Else
            ' Not connected, displaying error message
        End If
    End Sub


Received exception:

Code: Select all
NotSupportedException

frmConnecting::Connect+0x50
frmConnecting::frmConnecting_Load+0x16
Form::OnLoad+0x15
Form::_SetVisibleNotify+0x1d
Control::set_Visible+0x1f
Application::Run+0x7
frmConnecting::Main+0xd


If I use the connection.Open() function I can connect without any problems. What might be my problem?

(Note: I'm using version 3.50.10.1 of CoreLab.MySql)

Your code works fine here. Could you send a test project to reproduce the problem?

It may be the handheld device that needs an update. I'll come back later and report with version number and some new test results.

We reproduced the bug in Compact Framework and now working on it.

Alexey,

I saw there's a new version of the library available.
I read the change log but it doesn't seem this issue was addressed.
Is this correct? (Please prove me wrong ;))

Kind regards,
Dirck
