creating dll's, using in other projects... problem when recompile dll... help please!!!I have one project as activeX dll... it is a work in progress so it needs re-compile a few times a day... I have another project (also activeX dll) that has a ref to the first, as it uses some classes in the first... prob is when I re-compile the first, then go back into #2 to run it, it will not compile, telling me that it can not find a ref to the 1st! I then have to manualy uncheck the ref to the first, save #2, re-add the ref to #1, then it will work... ugh... Is this how it works, anytime I recompile I must reset the ref to the dll in the any project that accesses it? What about using the dll in VBA in Excel...(which I plan to do)... If I have some end users accessing the dll from vba code I have set up for them, then I need to add/edit the dll project and recompile... will I have to not only copy it to the end users machines, but also reset the ref to it as well??? Surely not... I must be missing something here... any help appreciated. Thanks

Also possibly consider project groups if you're still debugging both proj1 and proj2 and they're both referencing the same dll. hth Mark "spiffo" <no***@hotmail.com> wrote in message FYI, You can debug without recompiling.news:dihbv2$nh7$1@news.isdn.net... > new to vb, using 'classic' as it is now called I guess...vers 6... > > I have one project as activeX dll... it is a work in progress so it needs > re-compile a few times a day... > I have another project (also activeX dll) that has a ref to the first, as When ever possible, build in reverse dependency order... if (EXEa needs > it > uses some classes in the first... prob is when I re-compile the first, > then > go back into #2 to run it, it will not compile, telling me that it can not > find a ref to the 1st!

If I As Mark mentioned, the problem is most likely compatibility settings.

Keep in mind that you can't simply change things on a whim. If you create a method called "Frog" that takes a string, that method must be there and expect a string for the rest of the DLLs life. If you find that you need a similar method that expects 2 arguments instead of one, you can add a new method called "FrogEX" and use that one instead.... at least until you're ready to call it "done".... at which time, you can settle on which of the 2 (or more) methods you really need, break compatibility, rebuild and recompile any apps that need the DLL.
