I am going to have a beer now. Thanks to whoever brought up the whole order id question.... I needed to start working on this and his question forced my day to focus on and understand the order process...

Subject: twsapi: Re: VB Sample Project: How To Place An Order [Code]
Put a Text1 textbox on your form.
Put a Command1 command button on your form
Add a Simple BAS Module
Stick this in the Form: (and the rest in the Module)
Private Sub Command1_Click()
'here I have just plugged in literal values for the example
'of course you could pull these in as variables or control
properties
'such as a combo box text or what not...
Call PlaceNewOrder("BUY", 1, "ES", "FUT", "200209",
0, "", "GLOBEX", "", "MKT", 0, 0)
End Sub
Private Sub Form_Load()
'connection call
Tws1.Connect "", 7496
'initialize your module variables
Call InitVarsNewOrderMod
Text1 = "PLACE ORDER DEMO:" & vbCrLf & vbCrLf & _
"When you click Command1, a market order will fire
off for 1 Contract of September " & _
"ES. Keep clicking it and it will keep buying one at
market. Each time you click, " & _
"This box will fill with the order information stored in your array"
End Sub
'and use this for when you log out and relog in
'you can conditionally test next valid id in the module
Private Sub Tws1_nextValidId(ByVal id As Long)
'call a module level Sub that captures the IB id on log in
Call CaptureID(id)
End Sub
'now create a private sub that will handle the order routines
'the array captures the order info and stores it for you
'good idea IMHO to internally track this info and not rely
'on IB soley
Private Sub PlaceNewOrder(ByVal action As String, ByVal quantity As Long, _
ByVal symbol As String, ByVal secType As String, ByVal expiry As String, _
ByVal strike As Double, ByVal right As String, ByVal exchange As String, _
ByVal curency As String, ByVal orderType As String, ByVal lmtPrice As Double, _
ByVal auxPrice As Double)

'not the conspicuous absence of id in the arguements
