I'm developing av project in VB.NET

I'm using a SDK from a supplier which trough a event-drive-model which allows me to interact with the program..(long story..)
Whenever im using a msgbox function the msgbox always comes on the bottom or "under" the main app. as a separate window.
So the user have to click in the taskbar to move on or use alt-tab so he can address the message.
(see what i mean)?

Is'nt there a msgbox API around that i can use and connect to my app somehow?
get the handle of the msgbox and "bring it to top"?

(badly explained on a hot friday in norway but hope U get the picture)

Is your MainApplication form is set to   "TopMost = True"...  this may be the reason.
Because.. MsgBox()  is bydefault Topmost...

yes you can find a window and bring that window to top by playing with APIs

Declare Function FindWindow Lib "user32" Alias "FindWindowA" (ByVal lpClassName As String, ByVal lpWindowName As String) As Long
    Declare Function BringWindowToTop Lib "user32" Alias "BringWindowToTop" (ByVal hwnd As Long) As Boolean

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button13.Click
        Dim h As Long
        h = FindWindow(Nothing, "YOUR MESSAGE BOX CAPTION") ' this will bring your messagebox on top
    End Sub

Are you talking about a System Model dialog box?

My MainApp does not have a Form.
Let me try to explain a bit better.

It is the same way as if I Create a new exe project where i include a referce to Excel (with events)
When I start my VB.NET app all it does is start excel.

And  I can use the Excel-Events (in my .net app) to f.ex validate a cell input, but if i want to give the user a feedback that the input is not valid the msgbox comes in a "own window".
Clearer now?

Can I use this code when the msgbox is already there? I mean... the the code will halt until the msgbox buttin is pushed.

Ive made a small ex. using EXCEL and VB-.NET
Create a new standard exe project using sub main as the startup..

Public Class Class1
    Private WithEvents XLAPP As Excel.Application
    Private bolRunning As Boolean = True

    Public Sub New()
        XLAPP = New Excel.Application
        XLAPP.Visible = True
        While bolRunning = True
        End While

    End Sub

    Private Sub XLAPP_SheetActivate(ByVal Sh As Object) Handles XLAPP.SheetActivate

    End Sub

    Public Shared Sub Main()
        Dim XLClass As Class1 = New Class1
    End Sub

    Private Sub XLAPP_NewWorkbook(ByVal Wb As Excel.Workbook) Handles XLAPP.NewWorkbook
        MsgBox("Im activated") 'This is the one I want to 'hook up' in excel not as a "alone window" from the exe project
    End Sub
End Class


My original problem was is another library that are .NET (not COM) (if that is a differnce)

I don't think that this is possible, without a lot of Windows magic, that I wouldn't be able to help you with.
