[RESOLVED] Delay in a function(?)

Hey! I have a function, which checks two file sizes, one from an URI and one from my computer if they are the same or not, but the problem is, that the URI file is needed to be start downloading, and it takes some miliseconds while it gives me the value, but its too late, because my conditions are running, and it gives me only the 0. How can i set a delay between the download starting, and the condition? Thank you, and sorry for my bad english!

Code:

---

    Function check() As Integer
        Dim a As Integer
        wca = New System.Net.WebClient
        Dim uri As New Uri("http://fusioncountry.tk/custom.img")
        wca.DownloadFileAsync(uri, My.Computer.FileSystem.SpecialDirectories.Temp & "\temp1download.tmp")
        If (My.Computer.FileSystem.FileExists(hely & "\SAMP\SAMP.col") Or My.Computer.FileSystem.FileExists(hely & "\SAMP\SAMP.def")) And My.Computer.FileSystem.FileExists(hely & "\SAMP\custom.img") Then
            If Int(My.Computer.FileSystem.GetFileInfo(hely & "\SAMP\custom.img").Length) = meret Then
                a = 0
            Else
                a = 2
            End If
            Return a
        ElseIf My.Computer.FileSystem.FileExists(hely & "\SAMP\custom.img") Then
            If Int(My.Computer.FileSystem.GetFileInfo(hely & "\SAMP\custom.img").Length) <> meret And My.Computer.FileSystem.FileExists(hely & "\SAMP\SAMP.col") = False And My.Computer.FileSystem.FileExists(hely & "\SAMP\SAMP.def") = False Then
                a = 1
            Else
                a = 2
            End If
            Return a
        Else
            a = 2
        End If
        Return a
    End Function

    Private Sub wca_DownloadProgressChanged(sender As Object, e As DownloadProgressChangedEventArgs) Handles wca.DownloadProgressChanged
        meret = e.TotalBytesToReceive
        Int(meret)
        wca.CancelAsync()
    End Sub

Um, maybe you should put your comparison in the ProgressChanged event handler, given that that is where you know the size of the remote file. You don't need a delay. You just need to structure your code sensibly.

Okay, but how I return that value instead of the check function?

Where are you calling that 'check' method and what are you doing with the result?
