No, you can only use it in Visual Studio .NET (which is Visual Studio 6.7 as to my *knowledge* but ppl usually refer to it as 7, when they're not calling it .NET) we'll leave the VS6.0 and VS.NET differences for a different topic...
basicaly, VB just turned more object-oriented and supports calls like this
Code:
Dim XValue as Integer = 5; while VB6 has to do it like this V
Dim XValue as Integer
XValue = 5
they both support this kind of calls....
Dim Value# (as integer), but VB.NET can still use Dim Value# = 5
that's just a VB example ofcourse, there's many many more (well, not really

but thats just my oppinion)
anywayz, it won't work in VS6.0 either, because i have visual studio 6, and the only things that its good for (regarding softice) is its c++ 6.0 debugger......
oh yeah, and why didn't SoftICE recognize my MASM disassembler when i do have it installed ???
