My PAINT sub looks like that:

Code:

Private Sub frmMain_Paint(ByVal sender As Object, ByVal e As System.Windows.Forms.PaintEventArgs) Handles MyBase.Paint
        Try

            If mActive Then

            If Not game Is Nothing Then
                game.PlayFrame()
            End If

            Me.Invalidate()
            End If

        Catch ex As DirectXException
            Console.WriteLine("DX frmMain_Paint(): " + ex.ErrorString)
        Catch ex As Exception
            Console.WriteLine("frmMain_Paint(): " + ex.Message)
        End Try
    End Sub

My PlayFrame() looks like that:

Code:

Public Sub PlayFrame()

        gfx.Render()

        If mGameOver Then
            Close()
        End If

        Application.DoEvents()

    End Sub

my Render() looks like that

Code:

Public Sub Render()
        Try
            If Not mDevice Is Nothing Then

                If Not ValidateDevice() Then
                    Exit Sub
                End If

                mDevice.Clear(ClearFlags.Target Or ClearFlags.ZBuffer, Color.CornflowerBlue, 1.0F, 0)
                mDevice.BeginScene()

                mDevice.EndScene()

                If Not mDevice Is Nothing Then
                    mDevice.Present()
                End If
                End If

            End If
        Catch ex As Direct3DXException
            Console.WriteLine("DX Graphics.Render(): " + ex.ToString())
        Catch ex As Exception
            Console.WriteLine("Graphics.Render(): " + ex.ToString())
        End Try
    End Sub

my ValidateDavice() looks like that:

Code:

Public Function ValidateDevice() As Boolean
        Dim deviceState As Int32
        Do
        If Not mDevice.CheckCooperativeLevel(deviceState) Then

            If deviceState = ResultCode.DeviceLost Then
                Console.WriteLine("Graphics.ValidateDevice(): Device LOST ")
                Return False
            End If

            If deviceState = ResultCode.DeviceNotReset Then
                Try
                    mDevice.Reset(mPresentParams)
                Catch ex As InvalidCallException
                    Console.WriteLine("Graphics.ValidateDevice(): mDevice.Reset(mPresentParams) InvalidCallException ")
                    Return False
                Catch ex As DeviceLostException
                    Console.WriteLine("Graphics.ValidateDevice(): mDevice.Reset(mPresentParams) DeviceLostException ")
                    Return False
                Catch ex As DriverInternalErrorException
                    Console.WriteLine("Graphics.ValidateDevice(): mDevice.Reset(mPresentParams) DriverInternalErrorException ")
                    Return False
                Catch ex As OutOfVideoMemoryException
                    Console.WriteLine("Graphics.ValidateDevice(): mDevice.Reset(mPresentParams) OutOfVideoMemoryException")
                    Return False
                Catch ex As OutOfMemoryException
                    Console.WriteLine("Graphics.ValidateDevice(): mDevice.Reset(mPresentParams) OutOfMemoryException ")
                    Return False
                Finally
                    mfrm.Close()
                End Try
            End If
        End If

        Return True
    End Function

What is wrong? When app is running and I press Alt+Tab, then return to app, i see error

Set the device = nothing when the application regains focus. Once you destroy the device, then you need to reinitialize it (and all of the textures too).

Thanks a lot Aragorn7, but it doesnt seems to me the fully right way.
Finally I did it

And forms code looks like that:

Code:

        Me.SetStyle(ControlStyles.AllPaintingInWmPaint Or ControlStyles.Opaque, True)

    End Sub

    Private Sub frmMain_Paint(ByVal sender As Object, ByVal e As System.Windows.Forms.PaintEventArgs) Handles MyBase.Paint
        Try

            If mActive Then

            If Not game Is Nothing Then
                game.PlayFrame()
            End If

            Me.Invalidate()
            End If

        Catch ex As DirectXException
            Console.WriteLine("DX frmMain_Paint(): " + ex.ErrorString)
        Catch ex As Exception
            Console.WriteLine("frmMain_Paint(): " + ex.Message)
        End Try
    End Sub

    Private Sub frmMain_Closing(ByVal sender As Object, ByVal e As System.ComponentModel.CancelEventArgs) Handles MyBase.Closing
        mActive = False
        game.Dispose()
    End Sub

And my Game Class code:

Code:

Public Class ThisGame
    Implements IDisposable

    Public mGameOver As Boolean = False
    Public mFrm As System.Windows.Forms.Form

    Public Sub New(ByVal frm As System.Windows.Forms.Form)
        ******************
        * Init LIB vars
        gfx = New Graphics(frm)  gfx is a public variable of Vars module 
                                          (everywhere can access it)
        mFrm = frm

    End Sub

    Public Sub PlayFrame()

        Try
            gfx.Render()

            If mGameOver Then
                Close()
            End If


            Application.DoEvents()
        Catch ex As DeviceLostException
            Debug.WriteLine("ThisGame.PlayFrame(): Try to validate")
            gfx.ValidateDevice()
        End Try

    End Sub

    Public Sub Close()
        mFrm.Close()
    End Sub

    Public Sub Dispose() Implements System.IDisposable.Dispose
        gfx.Dispose()
        Application.Exit()
        System.Environment.Exit(System.Environment.ExitCode) FORCE an exit if it didnt exit
    End Sub
End Class

Now it works as I wanted. I can tab between applications, return to game
and continue to play.

The only problem this game do nothing for now

(just set and reset device

)
