Use One DLL in preference to Another? (* !RESOLVED! *)

Hi All,

Does anybody know of a way in VB to use one DLL in preference to another?

I.E. There is a version of MyExample.DLL on the PC, registered etc and sitting in "C:\WINNT\System32".

Now I Install my application and put another version of the MyExample.DLL in the same dirtectory as the EXE, but I don't register it...

Is there anyway to get my EXE to use the "local" version of the DLL, rather than the one in "C:\WINNT\System32"?

I know this is possible in other languages, just not sure about vb?

I believe it's possible with VB.NET and the MS .NET Framework, but with VB 6, I don't think it's possible, except if you application unregisters one DLL, and then registers the one you want to use...:(
Although don't quote me on that...

I would like to know how its done, could you please post how its done, thank you :p

How do you know I have cocktail umbrellas in my drinks!:eek: hehe

Ok, the solution is...

Install your exe and all of its dlls into the same DIR. DO NOT REGISTER THE DLL's.

Create an empty file in the same directory with the same name as your exe, including the extension, and add ".Local" to the end of its name.. e.g. "MyApp.Exe.Local"

Now windows 2000 will check for a .local file when starting an EXE, if one is found it uses local DLL's in preference to registered ones.

Aaargh.... and i thought he had a solution for wint9x/NT. :mad:

Sorry nihar, it may work on those platforms, its just this is the only one mentioned in the article, and the one I'm currently using...

Of course if this is part of COM+ then it will only work on 2000 and XP..
