<DIV> It wont be so much the existing functions that will change, its
more that there will be new ones added.</DIV>
<DIV>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.</DIV>

color=#0000ff size=2>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, <A

color=#0000ff size=2>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.</FONT></SPAN></DIV><!-- Converted from text/plain format -->

<DIV><SPAN class=796310320-25052006><FONT face=Arial size=2>What A
interested in knowing is, am I correct in understanding that Delphi 7 can
talk to a D2005 .Net webservice?</FONT></SPAN></DIV>
<DIV><SPAN class=796310320-25052006><FONT face=Arial
size=2></FONT></SPAN> </DIV>
<DIV><SPAN class=796310320-25052006><FONT face=Arial size=2>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.</FONT></SPAN></DIV>
