Problems w/ Forms

[RecumbentRider]

Skill level: advanced newbie

I'm having trouble understanding how to show/hide/dispose/bringtofront forms. Here's what I'm trying to do-
FrmMain_Load
User is looking at frmMain
User makes a selection from comboBox1
comboBox1_SelectedIndexChanged calls sub New() in Module1
(*1) sub New puts frmDialog on top of frmMain
frmDialog has 3 btns (btnNew, btnCopy btnCancel)
User clicks btnNew
frmDialog/btnNew_SelectedIndexChanged code sets strResponse to "New"
(*2) frmDialog disappears
Back to sub New()
[code]
(*3) sub New/ Case(strResponse), Case "New" puts frmDialog on top of frmMain AGAIN
[strResponse not needed after this]
User clicks btnCopy this time
frmDialog/btnCopy_SelectedIndexChanged code sets strResponse to "Copy"
(*4) frmDialog disappears, frmMain is there
Back to sub New/ Case(strResponse), Case "Copy"
[strResponse not needed after this]
[code copies a file]
(*5) end sub New (Exit??)
(*6) Return to frmMain to make another selection using comboBox1

Can you tell me what commands to use for *1 - *6? to do what I want to do?
I've tried many combinations.
so far...
frmDialog.ShowDialog() seems to work at *1
Me.Close at *2
frmDialog.ShowDialog() at *3
Me.Close at *4
If I do this at *5, *6

frmMain.Visible = false
frmMain.ShowDialog()

it looks like it works but it runs frmMain_Load again which does a bunch of stuff I don't want to do.
So *5 and *6 are the problem (I think)

Can you help??
Thanx [e-mail]

For *1, you want want to use .ShowDialog() on your dialog form. That forces the user to deal with that particular form before doing anything else. It will also block code, so your new sub won't continue until the form is dealt with.
That should actually handle *1 and *2, start with that?
Actually it looks like that is good for all of them, and you have that part.
Why are you calling Me.Close? That will close the window that that code is executed on?
