I would suggest making your own using a simple form and a timer...

[kayleigh]

that the only way?

[techgnome]

No... clearly there's another way... but as you pointed out... that's a lot of code.

here's a simple example:

Public Class Form1
 
    Private Declare Sub keybd_event Lib "user32" _
                      (ByVal bVk As Byte, _
                       ByVal bScan As Byte, _
                       ByVal dwFlags As Byte, _
                       ByVal dwExtraInfo As Byte)
 
    Private Const VK_RETURN As Byte = &HD
    Private Const KEYEVENTF_KEYDOWN As Byte = &H0
    Private Const KEYEVENTF_KEYUP As Byte = &H2
 
    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim t As New Threading.Thread(AddressOf closeMsgbox)
        t.Start(10) '10 second delay
        MsgBox("message")
    End Sub
 
    Private Sub closeMsgbox(ByVal delay As Object)
        Threading.Thread.Sleep(CInt(delay) * 1000)
        AppActivate(Me.Text)
        keybd_event(VK_RETURN, 0, KEYEVENTF_KEYDOWN, 0)
        keybd_event(VK_RETURN, 0, KEYEVENTF_KEYUP, 0)
    End Sub
 
End Class

It looks an interesting coding example. I might work through it solely because it works with the Win32 model; something which isn't really covered in MSDN.

I've found a very simple way to do this, using the windows API messageBox Call.

Private form2 As New Form()
<DllImport("user32.dll", CharSet := CharSet.Unicode)> _
Public Shared Function MessageBox(hWnd As IntPtr, text As [String], caption As [String], type As UInteger) As Integer
End Function
Private Sub timer1_Tick(sender As Object, e As EventArgs)
	form2.Close()
	form2 = New Form()
	MessageBox(form2.Handle, "test", "test", 0)
End Sub

This will open a new MessageBox, and close the previous one every time the timer ticks. What it does is it creates a messagebox under the hidden window form2. Closing form2 will then close the messagebox as well.

I haven't actually tried this in vb, I converted the code I wrote in c#... but it should work the same way.

A little modifications.

Usage:

msgboxautoclose("Sample message goes here", MsgBoxStyle.Information, "Title Message", 20)

Private Declare Sub keybd_event Lib "user32" (ByVal bVk As Byte,
                       ByVal bScan As Byte, _
                       ByVal dwFlags As Byte, _
                       ByVal dwExtraInfo As Byte)

    Private Const VK_RETURN As Byte = &HD
    Private Const KEYEVENTF_KEYDOWN As Byte = &H0
    Private Const KEYEVENTF_KEYUP As Byte = &H2

    Public Sub msgboxautoclose(ByVal Message As String, Optional ByVal Style As MsgBoxStyle = Nothing, Optional ByVal title As String = Nothing, Optional ByVal delay As Integer = 5)
        Dim t As New Threading.Thread(AddressOf closeMsgbox)
        t.Start(delay) '5 second default delay
        MsgBox(Message, Style, title)
    End Sub

    Private Sub closeMsgbox(ByVal delay As Object)
        Threading.Thread.Sleep(CInt(delay) * 1000)
        AppActivate(Me.Text)
        keybd_event(VK_RETURN, 0, KEYEVENTF_KEYDOWN, 0)
        keybd_event(VK_RETURN, 0, KEYEVENTF_KEYUP, 0)
    End Sub

hi paul.

awesome code,

but its possible set it only auto close for any error message box pop up .
