I'm having this InvalidOperationException
An error occurred creating the form. See Exception.InnerException for details. The error is: Object reference not set to an instance of an object.
pointing at this line of code:
Private Sub BeginningBalancesToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles BeginningBalancesToolStripMenuItem.Click
inventory.MdiParent = Me <--error here
inventory.Show()
End Sub
EDIT:
Im only using drag and drop for creating controls from the toolbox. The thing here is, everything works fine until I relocated AND decided to return panel_001 to its previous location by pressing ctrl-z in the inventory.vb during design time to revert the change I made. The program runs fine without error prior to that specific panel relocation. I never edited any codes in the designer.vb and in the inventory class. I strongly believe that a piece of code wasn't properly restored at the ctrl-z action in the inventory.Designer.vb. Is this a visual studio bug?
EDIT: I tried creating a new winform and attempted to start fresh by foolishly copying & pasting all the controls and the forms' class and was no good. I assume the problem does not lie under the striked-out line above.
