Forms acting unexpectedly - vb.net

Question

I'll try to explain this best I can.
I have windows form application that contaions numerous forms. The first form
to open is a non modal form that acts as command form to issue various formats to
the underlying reservation program. A second form also opens which is basically my
Main form for the application. This form contains multiple check boxes to run methods
that make changes to the reservation program. This form is also modeless. Each box that
is checked runs concurrently and performs methods to delete, change and add to the
res program below. Various boxes may be checked at any given time. Below is code to
handle the checkboxes:
Private Sub frmOWTMain_KeyUp(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles Me.KeyUp
If e.KeyCode = Keys.Enter Then
Me.Hide() 'here i want to hide the OWTMain form
Call ckforPNR()
If Me.cbPricing.Checked Then
Call doPricing()
Me.cbPricing.Checked = false
End If
If Me.cbUdids.Checked Then
frmUdids.Show()
Me.cbUdids.Checked = False
End If
If Me.cbMod.Checked Then
Call doModUdids()
End If
If Me.cbFare.Checked Then
Call doFareSavings()
Me.cbFare.Checked = False
End If
End If
Me.show() 'This is the problem. This runs during method calls. All I'm
'looking to do is re display the OWTMain form.
End Sub
At this point I would want to re display the OWTMain form above. This is
where I am having an issue. As you can see, a number of methods are called
which involve showing other forms to the user. I do NOT want any of these
forms to be modal because I want the original first opened form to still be
able to issue commands to the res program toview information needed by the other forms.
Here is an example of some of the method calls:
Private Sub doPricing()
Dim myPrice As New Pricing 'a call to another class that handles pricing
If myPrice.getTQT = False Then
frmAddPricing.ShowDialog() 'showing new forms
Else
frmCurPricing.ShowDialog()
End If
End Sub
Private Sub doFareSavings()
Dim myPrice As New Pricing
If myPrice.checkForFS = False Then
frmFS.ShowDialog() 'showing new forms
End If
If myPrice.checkForFS = True Then
frmFSVerify.ShowDialog()
End If
End Sub
When I call any of these methods the form OWTMain shows prematurely while other
forms from the called method are still running. I expected the code at the top to run
in order of the calls but that is not the case. I just want to re display the OWTMain
form after all the code is run. I have not been able to figure this out without
creating a ton of code to minipulate the opening and closing of the windows.
Any help with this would be greatly appreciated. Thank you.

Answer 1

This will check if all sub forms are closed and then re-show the main form.
remove the exitsing me.show()
Public Sub ReShowMainForm()
' add all sub forms to this check
if frmFS.Visible = false andalso
frmUdids.Visible = false andalso
frmFSVerify.Visble = false then
Me.Show
End If
End Sub
change xyzForm.Show to xyzForm.Show(me) to make the main form available as parent to the sub forms.
Handle the FormClosed event in each sub form and add the following code
DirectCast( me.parent, frmOWTMain).ReShowMainForm()
