Shawn,

I always use the patch functionality from Wise InstallMaster to create updates from our .exe. With this a 200k Patch is created from a 9 meg .exe.
The only thing that you need to have is an archive of the version(s) used by clients. With this it is possible to upgrade several build to the newest build with 1 update, but that will increase your update size (rule of a thumb, size of update is (Number of builds included + 1)*100k )

>Updating code on a client's site has always been an issue with our VFP product. We do so many modifications and fixes that we are constanly needing to update the clients... and this never seems easy.

>One problem is that if I change a .VCX then I have to recompile the application and send out the whole 25+ megs. The size alone can be a bear (having to move that large an EXE across the wire), and beyond that having to compile the whole thing as an EXE is sometimes complicated by that causing problems elsewhere.
