Cannot access a disposed object that was just created.

Question

Here is my code:
Imports System.Data.SqlClient
Imports System.Diagnostics
Imports System.IO
Imports System.Threading
Imports System.Text
Imports System.Windows.Forms
Module MigrationControl
Dim FormBulkLoadFailed As MessagePlatform
If runCommand(comSQL, cmdLoad, True) = -99 Then
'Informing user the Bulk Load failed.
FormBulkLoadFailed = New MessagePlatform(11)
FormBulkLoadFailed.ShowDialog()
End
End If
The FormBulkLoadFailed.ShowDialog() does nothing and the runtime properties says:
Cannot access a disposed object.
Object name: 'MessagePlatform'
How can something that was just created already be disposed?
Thank you,
Charlie

Answer 1

Does the MessagePlayform accept constructor accept an integer parameter?  You are passing an 11 to the form.  You probably have two constructors in the form.  The default with zero parameters and the one you are using with one parameter. 
I suspect the constructor is closing the form before it is displayed.  Test for nothing like in the changes below
Dim FormBulkLoadFailed As MessagePlatform
If runCommand(comSQL, cmdLoad, True) = -99 Then
'Informing user the Bulk Load failed.
FormBulkLoadFailed = New MessagePlatform(11)
if not FormBulkLoadFailed is nothing then
FormBulkLoadFailed.ShowDialog()
End
End If
