RCW DispId changed


hi all.

i'm using third party activex component. i've received new version of it (actualy version number same, api has changed). after generating rcw new component noticed, dispid methods has changed , new methods has been introduced. old rcw not work new activex version, because of dispid changes.

my qustion is: how can application work both activex versions? (a) have load different rcw based on witch version installed on user mashine, or (b) maybe can customize rcw work both version (e.g. creating dublicate methods different distids), or there any other posibility?

i have no experience com, maybe reasoning incorrect.

 

thanks help.

juozas.

that's major, major crime activex developer.  must go vendor , demand version that's either backwards compatible or uses different guids.  if don't, you'll stuck unsolvable versioning problem.
