Backwards compatibility of VB6 with VB5?

Visual Studio324
I've some concerns regarding backwards compatibility issues with VB6.



I have this situation where an application developed in VB6 is to be

deployed on a system running an application developed in VB5.



The installation package for the vb6 application replaces common

microsoft component files like COMDLG32.OCX on the system it is

installed on. Would the VB5 application be affected by this

installation?



I've been trying to do a detailed comparison between the components

(COMDLG32.OCX, COMCTL32.OCX, etc) used in VB5 and VB6, but i havent

been able find any good resources documenting this. Pls recommend some

gd links if u have any?



Thanks!

Possibly if it replaces all instances. The likelihood increases w/ more

of the other add-ons in use, however, I think, though.

Other than a general search for MSDN for knowledge base, I know of

nothing particularly related. MS hasn't ever been particularly

concerned about retaining backward compatibility, but most systems have

many other small programs and utilities that rely on the VB rtl so there

would have been many complaints if things were too egregiously broken.



Probably best you can do imo is to do a trial install that you can

rollback and test before an official rollout...

Well, I thought I had a fairly good vocabulary but I've got to admit that

one had me scurrying to dictionary.com ;-)
