waiting form get disappeared while executing long process

[skavinkar]

I am trying to display waiting message which is actually a form while long process is running in some different file. Issue i am facing is the form get disappeared once the process gets started but its still active and running the process

My code:

Dim objWait As New frmWaitupdate
    Dim strReply As String
 
    Dim ischange As Boolean
    Dim obj1 As New MyBO.UpdateSchemaBO()
    ischange = obj1.CheckSchemaChanges(Application.ProductVersion.ToString())
 
    If ischange = True Then
 
        lblMsg.Text = "Schema changes found please wait  Please wait."
 
        obj1.AddVersionTable(Application.ProductVersion.ToString())
        Me.Visible = True
 
        strReply = obj1.UpdateSchema(Me)
        If strReply <> "" Then
            MessageBox.Show(strReply, "abc")
        Else
            MessageBox.Show("Schema updated successfully", "abc")
        End If
 

        'objWait.Hide()
    ElseIf ischange = False Then
 
        MessageBox.Show("No schema changes found", "abc")
 

        End If
 
    End If

As the process goes in UpdateSchema() which takes around 30-45 sec to finish the form gets disappear.Is there any way to keep the form intact on screen until my process gets complete??

skavinkar, any task that's going to take that long will probably make your app unresponsive until it's finished. I would recommend that you place your long running function in another thread so the UI remains responsive. A fairly easy solution would be to place a background worker on your form. The background worker is nice because it allows you to show progress/status on the UI thread while keeping the main routine on another thread.
