I am not quite sure what you are asking here. If you
and new functions, and you want to use those new functions then you will need to
update the app. if you don't want to use the new functions then you don't
need to update the app.

Subject: RE: [DUG] Web ServicesIt wont be so much the existing functions that will change, its more that there will be new ones added.My question is, if/when a new function is added, how does the calling exe know that its ok to call it? From what I have seen, when you add a reference to a webservice, it creates a new PAS file that has all the functions etc in it, and therefor this is compiled into the exe, so if I add new functions one would assume that a new calling exe needs to be updated....which is what I want to avoid.Jeremy

Subject: RE: [DUG] Web Services
The point of web services is that they are language and platform agonistic. Therefore you can call a d.n web service from D7 etc. The restriction is that the web service must only require parameters and results that D7 can support. it is possible to make a .net web service that only .net can call (thanks ms) but it is as easy to make one that anything can accept. You might also want to look at using REST, http://blog.marcocantu.com/blog/soaprest.html.I believe it is considered bad form to change the spec of existing functions much as it is in dlls. You should version them instead. Adding a new function won't affect existing apps though.Regards

Subject: [DUG] Web ServicesHi All.We are looking at improving some stuff at work, and web services will be something I feel will help greatly.What A interested in knowing is, am I correct in understanding that Delphi 7 can talk to a D2005 .Net webservice?If the above understanding is correct, if I make a change to the web service, then I need to also change the exe calling the webservice? i.e. if I add new functon t the webservice, then the caling exe needs to know abou it etc. etc.is this correct?Thanks, jeremy
