First: are you using createobject()? You should be using form.NewObject() or form.AddObject() for this, or you won't get a combobox that you can see.

As to custom IAC code at runtime. No can do.
Code can only be created at design time.
However, with VFP6 sp3 and up you can create a class for it and COMPILE at run time. You can create the IAC code this way.
e.g.,

#Define CR Chr(13)
lcCode = "Define Class myCombo1 As combobox"+CR
lcCode = lcCode + " Procedure InteractiveChange"+CR
lcCode = lcCode + "   Wait Window this.value" +CR && here's where the custom stuff goes
lcCode = lcCode + " EndProc" +CR
lcCode = lcCode + "EndDefine"+CR
lcFile = "comboclass1.prg"
StrToFile(lcCode, lcFile)
Compile (lcFile)
thisform.NewObject("cboOne", "mycombo1", "comboclass1.prg")
With thisform.cboOne
     .top = 10    && or wherever
     .left = 10   && or wherever
     .RowSourceType = 1
     .RowSource = "one,two,three"
     .visible = .T.
EndWith
