Check out
Forward Pass. Freeware development tool with a desktop utility for scripting
& creation of CAB files for deployment. Supports JavaScript or emBedded Visual Basic(eVB) code.
Also Microsoft's
eMbedded Visual Tools 3.0 - 2002 Edition. This is a complete package much like M$ Visual Studio and is also free.
I like ForwardPass, but that's probably because I don't have any eVB knowledge.
