Hi Vesselin,
Is the extension specified in
ExgRegisterData (appCreatorID, exgRegExtensionID, "PRC");
case sensitive? (I've seen only lower case used and I've never tried
upper case.)
As an intermediate test point, does the receiver application ever get
sysAppLaunchCmdExgAskUser? (By the way, to receive multiple files I
think you'll eventually have to handle sysAppLaunchCmdExgAskUser and set
ExgAskParamType's result to exgAskOk so the transmitter won't time out
during the receiver's dialog ... at least that is what I ended up
doing.)
I hope that helps,
Greg
